STEREOTYPED AT THH BOSTON STEREOTYPE FOUNDRY. PREFACE. The quarryman, who has made excavations in the rocks for architectural materials, sometimes looks over the fragments which have been thrown aside, and finds blocks that seem to him worth preserving. Thus have I been doing with the literary debris, which has been quarried and wrought on special occasions, and after wards thrown aside. With some new dressing, I have ventured to hope that a part of them are worth pre serving, and this volume is the result. A brief history of the several articles is subjoined. The first article, entitled The highest Use of Learn ing, was" my Inaugural Address when assuming the presidency of Amherst College, April, 1845. The second, on The Relations and Mutual Duties between the Philosopher and the Theologian, was de livered as an Anniversary Address before the Porter Rhetorical Society, at the Andover Theological Semi- PREFACE. nary, in 1852. It was subsequently published in the Bibliotheca Sacra, from which it has been copied, by permission. The third, on Special Divine Interpositions in Nature, was given before the Theological Seminaries of Bangor and Newton, in 1853. This, also, was published in the Bibliotheca Sacra for 1854. The Wonders of Science compared with the Wonders of Romance, is a Lecture which has been delivered before literary associations in the cities of New York, Brooklyn, New London, Norwich, Lowell, Charlestown, Salem, Newburyport, and Springfield ; also at Amherst College, and in some other places. It has never before been published. The Religious Bearings of Man's Creation was preached as a Sermon before the Convention of Con gregational Ministers, in Brattle Street Church, Boston, May, 1854. It was also delivered as an Address before the Theological Society of Dartmouth College, in August, 1854. It has likewise been preached in Am herst College, in Springfield and Conway, Massachu setts, Brooklyn and Buffalo, New York, and Milwaukie, Wisconsin. In August, 1856, it was preached in Rev. Dr. Sprague's Church, in Albany, on Lord's Day morning, at the time of the meeting of the American Association for the Advancement of Science. By the PREFACE. local committee of that association it has been pub lished in connection with a Sermon by President Hop kins, of Williams College, delivered in the afternoon of the same day. The Sermon entitled TJie Catalytic Power of the Gospel was preached before the Massachusetts Home Missionary Society, at its anniversary in Boston, in May, 1852. It was published by the Society in pam phlet form. The Attractions of Heaven and Earth has been preached as a Sermon in Amherst College, in Amherst, West, East, and North Parishes ; in Hatfield, Whately, Enfield, South Deerfield, Conway, and Richmond, Massachusetts. Its chief peculiarity is the employment of diagrams. It has never before been published. The Sermon entitled Mineralogical Illustrations of Character, has been preached only in Amherst College, at an evening lecture. Its chief peculiarity is the employment of a few mineral specimens for illustra tion. This is the first time it appears in print. The Inseparable Trio was an Election Sermon, preached January 2, 1850, in Old South Church, Boston, before His Excellency George N. Briggs, His Honor John Reed, the Honorable Council, and the Senate and Hous*e of Representatives of Massachusetts, by whom it was published in the pamphlet form. It is 1* b PREFACE. added to this volume from a growing conviction of the importance of the leading principle advanced in it. A Chapter in the Book of Providence was delivered as an Anniversary Address before the Mount Holyoke Female Seminary, at South Hadley, in 1849, and pub lished in a pamphlet form. I give it a place in this volume chiefly to exhibit the outlines of the character of one of the most energetic and benevolent females of modern times. Tlie Waste of Mind is also an Address at the anni versary of the same institution, in 1842. It was pub lished by the trustees in a pamphlet form. Excepting the two or three last of the preceding articles, it will be seen that scientific facts and prin ciples are employed to prove or illustrate religious truths. This fact embraces so large a part of the volume, that I have felt justified in placing it upon the title page. I might have added many more articles of analogous character, but fear that I have already presumed too much upon the interest of the public in such productions. Amherst College, November 20, 1856.

The cause of education, in this country at least, is almost universally popular. Yet were we to pass around the inquiry among the different classes of society, why they regard it so important, we should probably receive very different answers. One man, himself uneducated, places its chief value in the means it affords of defence against the impositions of the de signing and unprincipled. Another values it chiefly because it enables him to take advantage of the ignorance of the world in promoting his schemes of self-aggrandizement. A third looks upon the means which education affords for acquiring property, as its highest use. A fourth regards the personal reputation, respect, and influence, which learning bestows, as its chief advantage. A fifth thinks of it mainly as an instru ment of advancing civilization, and multiplying the comforts and luxuries of life. A sixth estimates most highly its influ ence in elevating the lower classes of the community above the condition of mere animals and drudges, and in making them understand that the body is not the only part of man to be cared for. A seventh places the highest use of learning in its power of disciplining and liberalizing the mind, and delivering it from vulgar fears, superstitions, and prejudices ; and in giving to men just views of their rights, relations, and destinies. An eighth thinks most of the boundless fields of (9) 10 THE HIGHEST USE OF LEARNING. enjoyment which knowledge opens to the human mind, of a far more noble and refined kind than any dependent upon animal nature. A ninth makes its most important use to con sist in its bearings upon religion, both natural and revealed. Now, in my opinion, this ninth man has the right of the matter most decidedly ; and yet I fear that his opinion is not the most common, or the most popular. But to my convic tion, the religious applications of learning are by far its most important use ; and the occasion seems to be a fit one to de fend and illustrate this opinion. It needs, I believe, both defence and illustration. For though the belief is general that religion may derive some benefit from particular branches of learning, there is still an impression lingering on many minds, that some sciences are unfriendly in their bearings upon religion, and that others have no relations to religion. Much less is it generally believed that the strongest reason why we should sustain common schools, academies, and col leges, is, that we are thus promoting the cause of true reli gion. But if this be indeed true, then, when we give our property, our influence, or ourselves, to the cause of learning, we shall do it with a heartier good will and a more entire con secration ; and we shall the more cheerfully bear up under the trials, fatigues, disappointments, and perplexities that lie in our path. I would not, indeed, undervalue the secular advantages of learning. They are so obvious and so important, that I could not do it if I would. Those whose experience reaches back fifty, or forty, or even thirty years, have evidence in their own consciousness of the economical value of learning, too strong to be overcome by any speculative argument depreci ating its importance. When we compare the present condition of the world, and our own condition, with what they were in THE HIGHEST USE OF LEARNING. 11 our early days, we cannot but be. deeply impressed with the rapid progress of society, and the multiplication of secu lar advantages, and the means of comfort and happiness, growing out of- the advancement of learning. Branches of science and literature, which, at the beginning of this centu ry, were tabooed to all who were not residents within the walls of universities and colleges, and even some branches that scarcely had an existence then, are now the theme of familiar conversation in the workshop, on the farm, in the stage coach, the rail car, the steamboat, and the packet. And so simplified are the elementary principles of many of these branches, as to be brought within the comprehension of the child at the primary school. Instead of the stinted sources of information then possessed in a few small newspapers and periodicals in some of the larger cities, and a few republica tions of small European works, the country is now flooded with newspapers of all sizes below one that will swallow up an octavo, and with periodicals and books to suit all tastes, all purses, and all fancies, from the penny pamphlet up to the seven hundred dollar volumes of Audubon. Still more striking has been the progress of the useful arts from the application of scientific principles. In Great Brit ain, at this moment, steam performs a work that would re quire the unaided labor of more than four hundred millions of men ; and a work as great probably, in proportion to the pop ulation, in our own country. Improvements in machinery and in chemical processes have doubtless within this century made a still greater deduction from the amount of labor ne cessary ; and these improvements reach every class of the community ; pointing out to them an easier path to compe tence, and affording them leisure to cultivate their intellectual and moral powers. Then, too, how striking the change in 12 THE HIGHEST USE OF LEARNING. respect to intercommunkation, both on land and water! We now hardly give a serious parting to our friend who starts upon a trip of only some five hundred or a thousand miles, so soon shall we see him again. And even when we have bid him adieu, as he starts on foreign travel, we hardly begin to reckon his absence by months, certainly not as formerly by years, ere he greets us again ; having made the tour of Europe, or perhaps stood within the Holy City, or coasted the shores of the Black Sea and the Caspian, or gone down the Red Sea to India and the Celestial Empire, and returning by the Isthmus of Panama, he has completed the circuit of the globe. And besides the problem has just been solved, of car rying on a conversation and transacting business with our friend when absent, even though hundreds, and it may be thousands, of miles intervene between us. Now, these are advantages derived from the progress of learning so obvious as to be known and read of all men ; and, therefore, we are apt to suppose them the chief advantages. Whereas the applications of literary and scientific truths to religion lie more out of sight, and can be appreciated fully only by him who is well acquainted both with learning and religion, and who looks at their relations with the eye of a philosopher. We must dwell a little, therefore, upon these relations in order to sustain the position that has been taken. I need not argue before such an audience as this the supe rior importance of religious principles to all others. This will be admitted ; for all other truths have reference to time, these to eternity : all others regard man's mortal, these his immor tal interests : all others are limited by created natures ; these centre in the uncreated God. Religious principles, therefore, are in their very nature of infinite moment. Other truths have gradations of value ; but these are invaluable, because THE HIGHEST USE OF LEARNING. 13 necessarily immortal and infinite. Every thing, therefore, in literature or science, that discovers, illustrates, or confirms the eternal principles of religion, swells into an importance proportionably great. It remains, then, only to show that the wide fields of learning afford us such illustrations over their entire surface, and the position will be made out, that the re ligious applications of literature and science are the most important of all their relations ; and that, consequently, when we consecrate our property, our influence, or our lives, to the cause of education, we consecrate them to one of the noblest of all human enterprises. Accompany me now, my friends, as we rapidly pass around the circle of literature and science, in order that we may see what are the relations between religion and the different branches of human learning. We meet, first, with the ancient classics, whose study forms so important a part of a liberal education in modern times. The religious principles which they contain are, indeed, fa tally false ; and not much more consonant with modern views is their philosophy. Nevertheless, they afford most important aid in elucidating revelation. The very absurdity of the my thology and philosophy of the classics brings out, by contrast, in bolder relief the beauties and glories of Christian doctrines and Christian philosophy ; and instead of leading the student to embrace polytheism, they prepare his mind for the recep tion of the gospel. Besides, many passages of Scripture would be unintelligible, and others unimpressive, without that knowledge of ancient opinions and manners which the clas sics disclose. And then, too, how unfit to give a correct interpretation of Scripture is he who is unacquainted with the languages in which it was originally written ! It does not prove this position false to state, what is certainly true, that 2 14 THE HIGHEST USE OF LEARNING. many men have faithfully preached the gospel, and been in strumental of the conversion of great numbers, who were ignorant of classical literature. So there have been surgeons and physicians unacquainted with anatomy, physiology, and chemistry ; and they may have performed many skilful op erations and effected many cures, and thus done much good. But other things being equal, no one would feel as safe in the hands of such practitioners as in those familiar with the struc ture of the human system, and with the laws that govern it, and with the chemical nature and action of medicines. In difficult cases such practitioners would shrink from prescrip tions and operations ; or if they rashly attempted them, would be very likely to tie the omo-hyoid muscle instead of the ca rotid artery ; or to administer nitric acid in connection with mercury ; or by some analogous blunder, to put the patient's life in jeopardy. And mistakes alike dangerous, sometimes infinitely more so, because they involve the loss of the soul, must he be liable to make, who engages in the ministerial office ignorant of the original languages in which the Scrip tures were written. And if one such fatal mistake should result from his ignorance, what a terrible drawback would it be upon a whole life of devoted usefulness ! In modern times human learning has become so prodigious ly expanded, and so many new branches have been estab lished, that it is difficult to discourse intelligibly concerning it without defining the terms which we employ. In France and Germany, the word literature embrace's the whole circle of written knowledge ; and with many English writers it has the same wide signification. But often the meaning is restricted to those branches which treat of the social, moral, and intel lectual relations of man. Polite literature, or belles-lettres, is still more limited in its meaning ; embracing poetry, ora- THE HIGHEST USE OF LEARNING. 15 tory, and perhaps history, biography, and some other miscel laneous subjects. The term science is applied to those branches whose principles are considered as well settled ; and with the exception of some parts of mathematics, the term is chiefly confined to the material world ; although mor al science, and intellectual science, are phrases frequently used. Adopting these definitions, we might arrange all human knowledge under the three heads of Literature, Science, and Art. Let us first inquire into the influence of modern litera ture upon religion. And here it must be acknowledged in the outset, that not a little of the influence of modern polite literature has been very disastrous to religion. For much of it has been pre pared by men who were intemperate, or licentious, and se cretly or openly hostile to Christianity ; at least to its peculiar doctrines. And their writings have been deeply imbued with immorality, or infidelity, or atheism. Yet the poison has been often so interwoven with those fascinations of style, or thought, characteristic of genius, as to be unnoticed by the youthful mind, delighted with smartness and brilliancy. And even when the plague spots have been pointed out, it has tended, like the prohibition of the fruit of the tree of knowledge in Eden, to excite an irresistible desire to open the proscribed volumes, even though they should prove a second box of Pan dora. Perhaps no branch of literature has been oftener and more • successfully employed as a vehicle for the propagation of in fidel opinions than history. Rightly understood, and faithfully interpreted, it gives strong light and confirmation to revelation and to morality. But sceptical ingenuity has often been able to make its voice as ambiguous as a Delphic oracle, and as 16 THE HIGHEST USE OF LEARNING. fallacious as ventriloquism. In pagan Greece and Rome, their historians, except perhaps Tacitus, were even over cred ulous on the subject of polytheistic religion. And so in mod ern times, previous to the last century, the historian was usually the supporter of revealed truth. But the talented yet anomalous Bayle, in that manual of irreligion, his Critical Dictionary, led the way in converting facts into an engine against Christianity. Voltaire and others learned the lesson, which was perfected by Gibbon and Hume. So often, how ever, have their sophistries and cavils been exposed, that it is only the unwary who are now entrapped. The great mass of historical literature also, your Rollin and Ramsay, Miiller, Schlegel, Heeren, Goldsmith, Smollet, Russell, Turner, Rob ertson, and a multitude of others, are favorable to religion ; although a Von Rotteck, in the costume of a baptized infidel, rejects biblical history as fabulous. Religion, therefore, need have no fears from her alliance with History ; and, indeed, she may hope for many a rich harvest of illustration and con firmation from future researches ; for there are other papyri to be unrolled, other hieroglyphics to be deciphered, and other Sir William Joneses and Champollions to be raised up. Another most sacrilegious perversion of polite literature consists in clothing immorality and irreligion in the vestal robe of poetry. I say sacrilegious ; for poetry is the natural hand maid of pure religion. Hence it was chosen by the Holy Ghost as the appropriate language of prophets and other in spired men. But it is the appropriate language of all strong emotions, and may, therefore, be employed for giving an attractive dress to immoral and irreligious sentiments, as well as to those which are virtuous and holy. Accordingly, so wide has been this misapplication of the poetic talent, that in almost every age its highest efforts have been consecrated to THE HIGHEST USE OF LEARNING. 17 polytheism, or war, or amorous intrigues, or intemperance, or to secure favor from the great, by flattering their vanity. In'- deed, though the Old Testament is full of poetry, and though it has ever been employed in the religious worship of Jews and Christians, yet it seems not to have been imagined till lately, that this delightful art had been perverted and degraded by being employed to sustain heathenism, and to pander to intem perance, licentiousness, and war ; nor that it could ever be ma'de thoroughly Christian, and thus exalted in character and effect. The great poets of antiquity were so fully heathen, and some of them, as Anacreon and Horace, had woven so many garlands for the intoxicating cup, that it seems to have been taken for granted that th« muse could never be made to pour forth numbers as sweet and enticing on loftier and purer themes. Even the splendid efforts of Milton and Dante did not open the eyes of Christians to the true use of poetry. In deed, the polytheistic and warlike numbers of Homer and Virgil, and the bacchanalian songs of the ancient lesser poets, were piety and purity, compared to the philosophic blasphemy of Shelley, the atheism and profligacy of Byron and Moore, and — must I add ? — the bacchanalian songs of Robert Burns. Furthermore, if it be true, as Milton affirmed, that a poet's life is itself a true poem, we shall be obliged sadly to swell the list of modern poems devoted to vice and irreligion. For when biography informs us that Addison, Prior, and Steele were intemperate, that Thomson was a voluptuary, Goldsmith dissipated, Sterne a decided sensualist, and that even Johnson could practise abstinence but not temperance, and when we know, that though Pope's constitution was too delicate to al low him to indulge in luxurious excesses, yet his writings show a bad preeminence of wantonness and indecency, we are led to exclaim with Milton, — 2* 18 THE HIGHEST USE OF LEARNING. " God of our fathers, what is man ! Nor do I name of men the common route, That, wandering loose abroad, Grow up and perish as the summer fly, — Heads without name, no more remembered, — But such as thou hast solemnly elected, With gifts and graces eminently adorned, For some great work — thy glory." And then, too, consider the moral character of modern dra matic poetry, so decidedly worse than the noble tragic poetry of antiquity. From the days of Dryden to the present, — for even Shakspeare, with all his splendid moral sentiments, was undoubtedly a libertine in principle and practice, — scarcely a dramatic poet has appeared %hose " entire unweeded vol umes," as Hannah More calls them, can be conscientiously recommended, save the Comus and Samson Agonistes of Mil ton, and a few other plays of kindred character. We have seen, too, that lyric poetry — more influential than any other upon public morals — has been prostituted to the cause of in temperance and revelry, from the time when Anacreon indit ed his ' H yt] fisXaiva nlvsi,ar\d Horace his Nunc est bibendum, down to the period when Burns exclaimed, " We'll tak' a cup o' kindness yet, For auld lang syne ; " or, still later, when the echo came from Moore, — "Friend of my life, this 'wine cup sip." But thanks be to God, that in these latter days he has cre ated some greater and some lesser Christian lights, and placed them in the poetic firmament, where they already begin to rule the day and the night. First came Milton ; a permanent THE HIGHEST USE OF LEARNING. 19 sun, not immaculate indeed, but full of glory, and destined for a long time to rule the day. Then appeared a milder lu minary ; foremost in the train of evening, and delightful to look upon, as reflected from the volumes of Cowper. And a noble train of kindred lights, most of them indeed lesser stars, have since shone in the literary heavens, bearing the names of Watts, Heber, Montgomery, Young, and others ; to which I might add several lights that have dotted the darkness of our western hemisphere. We were also startled, not long since, by the flash of a meteor shooting athwart the eastern heavens, and having marked out the Course of Time, vanishing from sight,— " As sets the morning star} which goes not down Behind the darkened west, nor hides obscured Among the tempest of the sky, but melts away Into the light of heaven." Nor ought I to omit to point to that noble luminary, which, for so long a period, has been burning with a mild and steady light above the lakes and mountains of Northern England, and which gives us some foretaste of what the literary hem isphere will be when poetic inspiration shall consent to receive a higher inspiration from the fountain of Scripture — far purer than Castalia. To bring about that golden age of poetry, should be the grand object of its cultivators ; especially of those who can claim the nascitur, non jit. Then, and not1 till then, will it be seen how noble an auxiliary to virtue and re ligion is the poetic element in man. There is another department of polite literature that has been, still 'more than poetry, monopolized by vice and irreli gion, and which, I fear, will be still harder to reclaim. To minds averse to close thinking, to those whose tastes and hab its are all artificial, and who have never acquired a relish foi 20 THE HIGHEST USE OF LEARNING. the beauties and wonders of nature, as well as to those who are the slaves of appetite, and passion, the novel and the ro mance have ever possessed irresistible attractions. And since these three classes form, to a greater or less extent, the prin cipal part of society, this is the literature that is most widely and abundantly diffused. And while the demand has created a supply, so, according to a principle of political economy, a surplus supply has increased the demand. The pen and the press have been prolific beyond all precedent ; and the quality of the article has varied according to the demands of fashion. At one time the gross and disgusting descriptions of Fielding and Smollet met the popular taste. Anon, what Hannah More calls the " non-morality " of the Great Unknown, was in excellent gout. And since that prolific fountain has been dried up, others, who, alas for the cause of virtue and reli gion are too well known, have not failed to disgorge tales of all sorts, suited to every variety of appetite, from the most delicate and refined to the most gross and grovelling. For, like the frogs of Egypt, these productions have not been con fined to the boudoirs oi the literati, nor to the centre tables and withdrawing rooms of wealth and fashion, but have found their way to the kneading troughs of the kitchen ; com ing there, it may be, in one of those, enormous products of the modern press that might be mistaken for a winding sheet, and which, I fear, has proved the winding sheet of many a noble intellect. I am aware that not a few authors, disgusted with these perversions of fictitious literature, have made many praise worthy efforts to turn its current into the channels of virtue and religion. Nor have they failed to obtain many interested readers. But I fear that in most cases it is the well-arranged story, and not its moral, which has awakened interest ; — THE HIGHEST USE OF LEARNING. 21 " First raising a combustion of desire, With some cold moral they would quench the fire." But Leviathan is not so tamed. Yet the fact that the love of novelty is so strong naturally in the heart, shows us that in some way or other it was meant to be gratified. And when we learn that the wonders of nature far transcend the won ders of romance, is it not evident, that if men can be brought to love nature, and those branches of knowledge which unlock her Elysian fields, this desire can be fully satisfied with real ities, without the aid of fiction ? I have little hope that any successful headway can be made against that morbid love of fiction which has become the almost universal passion, until you can implant in man's heart a love of unsophisticated na ture. This once done, and the fascinations of romance would become powerless under the overmastering influence of the new affection. To restore nature, therefore, to the throne of the heart, and expel the meretricious usurper, is the noble work that lies before the scholar of the nineteenth century. And when it shall be accomplished, as I doubt not it will be, and the deluge of fictitious literature that now almost buries the civilized world, shall have passed into the limbo of for- getfulness, it will be found that a mighty barrier to the prog ress of true knowledge and true religion has been taken out of the way, and that the heart which is alive to nature's beau ties is well prepared to love the God of nature, as well as the God of revelation. It is not necessary to spend time in showing that rhetoric and oratory, two other important branches of polite literature, are capable of the same perversion to unworthy purposes as the subjects already noticed. In every human heart there are chords, which, when struck by the silver bow of the rhetori cian, or the magic wand of the orator, cannot but vibrate and 22 THE HIGHEST USE OF LEARNING. give back a response. But when stormy passion, or reckless irreligion, sweeps over those chords, they return only discord ant sounds, that grate harshly upon the ear of virtue and pi ety. But when they are touched by the delicate and skilful hands of true benevolence, the tones which they return resemble the music of heaven, and they excite the spirit of heaven all around. To promote that spirit is doubtless the grand object to which the Creator intended the flowers of rhetoric and the strains of eloquence should be devoted. How immensely im portant, then, that Christian scholars should rescue these branches from the hands of the unprincipled and the wicked, and convert them to their legitimate use, as auxiliaries ©f vir tue and religion ! Some worthy men, I know, look with a jealous eye upon the use of rhetorical and oratorical skill in aid of religion. They feel as if no attempt should be made to set off and rec ommend the naked truth. But, as remarked by Dr. Camp bell, how much better for the minister of the gospel to write so as to make the critic turn Christian, than to write so as to make the Christian turn critic ! It is not in human nature to avoid receiving a powerful im pression from a skilful choice and collocation of words ; and why should not religion avail itself of this means of giving truth a keener edge ? It may, indeed, be carried to excess, as Dante seems to have done in his descriptions of the phys ical torments of perdition. But Milton, while he has given an awful distinctness and force to those same torments, has not exaggerated them ; and why may not religion use this power, as any other proper means, to impress divine truth ? In this respect, thus far, the children of this world have been wiser than the children of light. In passing from literature to science, on the great circle of THE HIGHEST USE OF LEARNING. 23 human knowledge, we meet with intellectual and moral phi losophy. But so obvious is the connection between the latter and the principles of religion, that we need not delay upon its elucidation. For every theory of morals, that is not radically defective, makes the origin of moral obligation identical with that of religious obligation. So that, in fact, moral philosophy is only one branch of natural theology. I regard politics, also, or the principles by which nations should be governed and regulated, as only a branch of ethics ; or, rather, as a special application of the principles of morality and religion ; though I greatly fear that expediency and self-interest have thus far been the basis of political action more frequently than moral or religious principle. By some writers, intellect ual philosophy, or psychology, or metaphysics, as they would rather choose to denominate the science, has been supposed, upon the whole, quite disastrous to religion. For when they consult ecclesiastical history, they find that the most fatal er rors in religion have usually been based upon some false sys tem of metaphysics, and that behind its hypothetical and unintelligible dogmas, the ablest sceptics have intrenched themselves. They regard " the modern philosophy of the human mind, for the most part, as a mere system of abstrac tions," " having almost nothing to offer of practical instruc tion ; " and although " the philosophy of the agency of sen tient and voluntary beings is a matter of rational curiosity, it is nothing more." I quote here, for the most part, the language of an able re cent author. But admitting the truth of these statements, they show one thing at least ; that unless theologians are fa- >- miliar with the systems of mental philosophy, so ably defend ed by eminent men, how can they hope to expose and refute such men when they employ metaphysical subtleties to per- 24 THE HIGHEST USE OF LEARNING. vert religious truth ? If the theologist does not display equal acuteness with the ontologist, the latter will triumph in his as saults upon religion. And if it be a false metaphysical philos ophy that has led a man to adopt a false religious creed, how important that the advocate of religion should be able to meet the errorist on his own ground, and not only to show him that he started wrong, but to put him upon the right track ! " If it be a murky or misty region," says a late writer, " carry the blazing torch of demonstrated truth into every cloudy cave and den, encompass every fastness where error lurks, and pour in the fire of a burning logic. The surest way to get protection from the open, and especially the secret ravages of a mischievous beast, is to hunt him down in his own lair." * But it is said, that all experience shows that there is no safety save in keeping religion entirely aloof from metaphys ics. What centuries of disaster followed the attempt of the ancient fathers to incorporate the metaphysics of Platonism with Christianity ! And how much longer in the dark ages did the pall of ignorance and a perverted Christianity vest upon the world, because it was held down by the Peripatetic Philosophy, resting on it like an incubus ! In our own day, too, we have seen a glacial period commence in a portion of the church, from the freezing influence of German meta physics, which threatens to be as long and as rigid as the analogous geological period. Now, were the question whether it were better for men to receive with childlike confidence the declarations of the Bi ble, without reference to ontological systems, all, probably, would reply in the affirmative. But the difficulty is, that in- * Professor Fiske's Address at East Windsor, p. 8. THE HIGHEST USE OF LEARNING. 25 genious and speculative men will construct their philosophical strait jackets, into which they will force the doctrines of revelation. And when the friends of piety see that Religion is panting and almost strangled by this cramping Procrustean process, how shall they liberate her ? They must have help to do it ; and denunciation and mere zeal will not bring help. They must show by a careful examination and measurement of the entire warp, and woof, and cut of this philosophical dress, that however agreeable it may be to the latest fashion, it cramps the heart and the vitals, stops the circulation of the blood, and is shrivelling up the extremities ; and then will all the friends of religion join in stripping off the murderous vestment. Do you suppose that the errors of Platonism, and the peripatetic philosophy would ever have been weeded out from Christian doctrines, except by men who had so thorough ly examined them as to be in no danger of plucking up the truth also ? Who but metaphysicians could have exorcised that famous Plastic Nature, conjured from the " vasty deep," by so powerful a necromancer as Cudworth ? Who but men > versed in the subtleties of dreamy abstractions could have coped successfully with the Scottish prince of sceptics, when he had gathered a dense fog around him, and under cover of it had assailed the first principles of all religion ? Had Kant been unskilled in the abstruse speculations of mental philoso phy, he could not so effectually have demolished the panthe ism of Spinoza ; and still more essential is such knowledge to show the fallacy of those more recent forms of the same doctrine, the natural pantheism of Schelling, and the idealism of Fichte. Another effort of the German mind is to show that the ar- . gument from design, to prove the divine existence, as ad vanced by Derham, Ray, Paley, and the Bridgewater Trea- 3 26 THE HIGHEST USE OF LEARNING. tises, is false, and that the idea of God is derived from a sort of intuition of the pure reason ; nor could the external world possibly excite the idea of God. These opinions have gained not a little credence in this country, falling in, as they do, with what is called a spiritual philosophy, or transcendental ism. Now that there is a moral order in the world, and in the mind itself, and that the understanding, perceiving this, naturally infers that a Being of infinite moral perfections must be the author of both, — because we instinctively refer every effect to a cause, — cannot be doubted. But on this view, this moral argument, as it is called, becomes only a single ex ample of the argument from design ; and by no means inval idates or supersedes other forms of the argument derived from the external world. Dr. Paley's argument was indeed defec tive, because he did not refer to mental philosophy to prove the spirituality of the Deity. But that defect is abundantly supplied by Chalmers, Crombie, and Brougham, so that now the argument which Paley labored to establish is impregna ble ; but it will require the vigorous efforts of men versed in abstruse metaphysics to bring it out of the fog and dust with which it has been enveloped. I have alluded to transcendentalism, dignified as it has been by the name of " spiritual philosophy," in distinction from the Baconian or inductive, which is called " sensuous." This is also a product of German metaphysics ; and when one sees what an absolutely unintelligible jargon is used in its enunci ation, by its ablest originators, such as Fichte, Schelling, and Hegel, he finds it difficult to conceive how it has exerted such an influence upon religion. But the fact is, there is always to some minds, especially in youth, a wonderful charm in a philosophy that is esoteric. They love to believe themselves capable of discovering a hidden meaning in facts and princi- THE HIGHEST USE OF LEARNING. 27 pies, which the uninitiated cannot discover. Hence, let some man of real talents and learning, as Swedenborg, for instance, solemnly and pertinaciously declare that he does " see what is not to be seen," and he will not want followers, who soon come to have a clear vision for double senses and spiritual meanings. Indeed, a man of talents has only to be obscure in his style and meaning, in order to be regarded by a large proportion of the world, and among them not a few recently fledged literati, as very profound. On the contrary, that beau tiful simplicity and clearness of style and thought, which are the result of long and patient investigation, and which charac terize the highest order of talent, are regarded by the same class as evidence of a superficial mind and destitution of gen ius. Accordingly, the temptation is very strong with writers and public speakers, who would be popular, to wrap them selves in the mantle of mystery and obscurity ; so that the remark of Dr. Griffin is too true, that the last attainment of the orator is simplicity ; and we may say the same, also, in respect to the philosopher. But if men of talents will mount in the air balloon of metaphysical speculation, into transcen dental regions of clouds and nebula?, and through their speak ing trumpets announce the discovery of new worlds, unknown to the Bible or to science, Christian men must ascend after them in a similar vehicle, bearing with them the torch of truth, to ascertain whether a fog bank has not been mistaken for a planet. I have thus far spoken of the value of mental science as a necessary means of detecting religious errors originating in the same science. But it has also many direct and important bearings upon religious truth. Did the time permit me to point them out, however, it would be little more than a repe tition of what has been recently said better and more fully 28 THE HIGHEST USE OF LEARNING. than I can do, by one of my colleagues.* I pass, therefore, to another important sign in the great zodiac of human knowl edge. On that circle mathematics follows naturally after metaphysics, because it furnishes us with the noblest exam ples of abstract truth in the universe. But I fancy that I hear one and another whispering, " What possible connection can there be between mathematics and religion ? " The pure abstractions of this science do not, indeed, lead the mind directly to a Deity, since they may be conceived to be necessary and eternal truths. They are not the result of an induction from facts, but of a comparison of ideas. And it is the facts of the natural world that most strik ingly discover to us the wonders of adaptation and design, and lead the mind irresistibly to infer a Supreme Being. But what is the basis on which most of this adaptation and design rests ? Chiefly, I answer, the laws of mathematics. Look up to the heavens, and you will find those laws controlling all the movements of suns and planets with infallible precision. Every movement on earth, also, which is either mechanical or chemical, is equally dependent upon mathematical laws. Vital operations, too, so far as they result from chemical and mechanical forces, must be referred to the same principles. I do not assert that life and intellect are governed by mathe matical laws ; but their operations have all the precision of mathematics, and, I doubt not, could be predicted by angelic minds, certainly by the Deity, with as much certainty as the astronomer foretells an eclipse or transit ; and really I do not see but the same principles would guide the calculation in the one case as in the other. In short, so entirely dependent are the movements of the universe upon mathematical laws, that * Professor Fiske's Address at East Windsor. THE HIGHEST USE OF LEARNING. 29 to alter or annul these laws would be to restore the reign of Chaos and old Night. Let but a single axiom or corollary of mathematics be changed, and I doubt not that wild disorder and ruin would soon take the place of the adaptation and beautiful design that now meet us at every step. Mathematics then forms the very framework of nature's harmonies, and is essential to the argument for a God. Instead of having no connection with religion, it lies at the foundation of all theism. It seems to me, also, that mathematics aids us in the con ception of some religious truths, difficult from their nature to be conceived of by finite minds. All the attributes of the Deity, being infinite, are of this description. But the contem plation of an endless series in mathematics gives us the near est approach to an idea of the infinite which we can attain. Follow the series, indeed, as far as our powers will carry us, and we are still no nearer the end than when we started. But we have got hold of the thread that would conduct us, if our Dsedalian wings did not fail us, across that interminable abyss which separates the finite from the infinite ; and when we transfer our mathematical conceptions to the Deity, we can hardly fail to meditate upon his glories with deeper amaze ment. To many minds all explanations of the biblical doctrine of the Trinity appear so absurd and contradictory as not to ad mit of belief. Let it, however, be stated to such a man, for the first time, that two lines may approach each other forever without meeting, and it will appear to him as absurd as the doctrine of the Trinity. But after you have demonstrated to him the properties of the hyperbola and its asymptote, the ap parent absurdity vanishes. And so after the theologian has stated, that by divine unity he means only a numerical unity, in other words, that there is but one Supreme Being, and 3* ' 30 THE HIGHEST USE OF LEARNING. that the three persons of the Godhead are one in this sense, and three only in those respects not inconsistent with this unity, every philosophical mind, whether it admit or not that the Scriptures teach the doctrine of the Trinity, must see that there is no absurdity or contradiction in this view of it. Hence it may happen, and indeed it has happened, that the solution of a man's difficulties on this subject may originate in a proposition of conic sections. Other peculiar truths of revelation receive striking support from the application of mathematical principles. Among these is the doctrine of special or miraculous providence. Professor Babbage, in that singular yet ingenious work, called the Ninth Bridgewater Treatise, has shown mathemat ically, that miracles may have formed a part of the original and foreordained plan of the universe, and that their occur rence may be as really the result of natural laws as ordina ry events — a doctrine which, indeed, had been previously advanced by Butler. And in this way is the famous objection of David Hume to miracles proved by mathematics to be groundless. Other religious applications of mathematics might be point ed out. But we must hasten forward to that wide space on the circle of human knowledge, occupied by the inductive sci ences. These comprehend, in fact, all those branches that relate to the material universe ; and when we have glanced at them, we shall have completed the circuit of literature and science. And here, at the outset, we remark, that from these sciences have been gathered that great mass of facts which constitute the essence of natural theology, by such men as Newintyt, Ray, Derham, Wollaston, Paley, Brown, and the authors of the Bridgewater Treatises. The a posteriori argument for THE HIGHEST USE OF LEARNING. 31 the divine existence rests upon them, and, indeed, almost all the truths pertaining to the character of the Deity and his government that nature discloses. They are arguments which all men can readily understand and appreciate ; for although a few metaphysical minds have endeavored to throw doubt over the validity of the argument from design, as I have al ready stated, yet this is in fact the only evidence that does interest and satisfy the great mass of men. When they see such wonderful effects as physical science discloses, they are led irresistibly, by a universal law of the human mind, to re fer them to some adequate cause ; and no cause can be ade quate save an infinite Deity. Natural theology has selected only the most striking of these effects. But in truth every fact of inductive science furnishes an argument for theism. So that to a man in a morally healthy state, every scientific truth becomes a religious truth, and nature is converted into one great temple, where sacred fire is always burning upon the altars, where hovers the glorious Shekinah, and where, from a full orchestra, the anthem of praise is ever ascending. In accordance with this view, we find that the most gifted minds, and indeed a large majority of all minds that have de voted themselves to inductive science, have been the friends of religion. And here we reckon the princes of the intel lectual world, such as Newton, Kepler, Galileo, Pascal, Boyle, Copernicus, Linnaeus, Black, Boerhaave, and Dalton ; and among the living such men as Herschel, Brewster, Whewell, Sedgwick, Owen, and a multitude of others. The very same argumentation that leads such original discoverers to derive the principles of science from facts in nature, carries them irresistibly backward to a First Cause ; and, indeed, the induc tive principle, as developed by Bacon, forms the true basis on which to build the whole fabric of natural religion ; and he 32 THE HIGHEST USE OF LEARNING. who fully admits the truth of natural religion, is in a state of preparation for receiving revealed truth to supply its defi ciencies. So that, upon the whole, the inductive sciences are of all others most favorable to religion, and the most intimate ly connected with it. I shall doubtless be met here by the objection, that not a few distinguished men, found in the ranks of inductive science, have been thorough sceptics. And here the names of some of the most able mathematicians of modern times, such as La Place and D'Alembert, will be adduced. We shall be re ferred to the Nebular Hypothesis of the former, and to the Encyclopaedia of the latter ; both of them intended to lay the axe at the root of all religion, and to cover nature with the pall of atheism. But such anomalies as these are explicable in consistency with the general position that inductive science is eminently favorable to religion. For in the first place, these men were atheists in spite of science, rather than through its influence. The spirit of the times, and of the country in which they lived, was dissolute and atheistic ; and the moral feelings of D'Alembert, at least, were so corrupt that nothing but atheism could keep conscience quiet. In the second place, they were distinguished in abstruse mathe matics, rather than in inductive science ; and it cannot be de nied, that when men devote themselves almost exclusively to abstractions of this nature, they are apt to look with suspicion upon the less certain, but far higher and more important evidence of moral reasoning ; or rather, they attempt to ap ply the subtleties of the higher mathematics to religion, and of course fail of arriving at correct results, because the sub jects are totally diverse, and must be understood by entirely different modes of analysis. Bonaparte, who was quick to discover character, made La Place one of his ministers, but THE HIGHEST USE OF LEARNING. 33 soon saw that he did not discharge his duties with much abil ity, because, as the emperor said, " he sought subtleties in every subject, and carried into his official employments the spirit of the method of infinitely small quantities," employed by mathematicians. But the grand difficulty with such men is, that by confining their attention so exclusively to one de partment of knowledge, and to the cultivation of one set of faculties, by a well-known law of physiology they dwarf all the other powers, and really become less capable of judging of other subjects than ordinary men, who cultivate all their faculties in due proportion. This is strikingly exhibited in the Nebular Hypothesis of La Place. He really thought that it rendered a Deity unnecessary in the formation of the uni verse. But the merest tyro in moral reasoning sees, that, even admitting the hypothesis, a designing, infinitely wise, and powerful Deity is just as necessary as without it. It only throws farther back the period when this designing and crea tive interposition was exerted ; and even the Christian philos opher feels no difficulty in adopting this hypothesis, through fear of its irreligious tendency. The fact is, that La Place, though a giant in mathematics, was only a liliput on other subjects. It ought not to be forgotten, also, that neither of the eminent infidel mathematicians whom I have named were original discoverers, like Newton, Copernicus, and Boyle. In making their discoveries, these latter men were led to take broad views of science, and to examine the original as well as final causes of events ; whereas such men as La Place and D'Alembert only carried out and illustrated the principles discovered by others. In tracing out these illustrations, they did, indeed, discover amazing acuteness ; but their views were so much confined, that they were but poor judges of the rela tions of science to religion. They were excellent mathema- 34 THE HIGHEST USE OF LEARNING. ticians, but poor philosophers. For in the noble language of Sir John Herschel, one of the brightest living ornaments of in ductive science in Europe, " the character of the true philoso pher is, to hope all things not impossible, and to believe all things not unreasonable." But the character of these men would be better described by saying, that they doubted and denied every thing that could not be proved by mathematics. They are examples of malformation and distortion in the philosophical world, instead of fair proportion and full devel opment. There is another circumstance which has deepened the im pression that the inductive sciences are, to some extent, un favorable to religion. Scarcely any important discovery has been made in these branches, that has not been regarded for a time, either by the timid and jealous friends of religion, or by its superficial enemies, to be opposed at least to revelation, if not to theism. When Copernicus demonstrated the diurnal and annual revolutions of the earth, the infidel saw clearly that the facts were in opposition to the Bible ; and the theolo gian was of the same opinion, and arrayed Scripture authority, as well as compact syllogisms, against the new astronomy. But the Christian soon learned that he had misunderstood the language of the Bible, because he had read it through the medium of a false astronomy. So too, when the Brahminical astronomy was first brought to light, and the epoch of the Tirvalore tables was thought to be nearly as early as the Mosaic date of man's creation, scepticism began to exult. But the tone changed when it was ascertained that this epoch was supposititious. More recently, French infidelity saw in the Zodiac of Denderah a refutation of the biblical chronol ogy. But when it was ascertained that the position of the signs on that Zodiac, in respect to the colures, had reference THE HIGHEST USE OF LEARNING. 35 to the commencement of the Egyptian civil year, and not to the precession of the equinoxes, this fancied discrepancy also vanished : and now, when both biblical interpretation and as tronomy are better understood, every one confesses, not only that the science is in harmony with revelation, but that it af fords some of the most splendid illustrations of religion to be found in the whole circle of learning. When, at the beginning of the present century, the great dis covery was announced, that the principal part of the solid materials of the earth had been oxidized, or in popular lan guage had been burned, both the baptized and the unbaptized infidel at once declared, that the final destruction of the earth, as described by Peter, was impossible, since it is no longer combustible ; and since the apostle had thus erred, because not acquainted with modern chemistry, the idea of his inspira tion must be given up. It was ere long found, however, that the apostle's language had been misunderstood, through the influence of the false opinion, still widely entertained, that to burn a substance is to destroy or annihilate it. But when chemistry showed that combustion only changes the form of substances, and cannot annihilate a particle, the apostle's meaning was found perfectly to correspond to such an idea : and it is now obvious, that he meant to teach simply, that whatever upon or within the earth is combustible, will be burned, and the whole mass of the globe be melted. . So that now the tables are completely turned ; and we find, not only no contradiction between his language and chemistry, but a striking proof of its inspired origin, in the fact, that though written when chemistry was not known, it should be found in perfect harmony with the researches of that science. And the same remark may be applied to the whole Scriptures in their relation to all science. The most eagle-eyed sagacity 36 THE HIGHEST USE OF LEARNING. of the nineteenth century has been unable to detect a single discrepancy between the two records. The same cannot be said of any false religion. The Shasters of Hindostan contain a false astronomy, as well as a false anatomy and physiology, and the Koran distinctly avows the Ptolemaic system of the heavenly bodies ; and so interwoven are these scientific errors with the religion of these sacred books, that when you have proved the former you have disproved the latter. But the Bible, stating only facts, and adopting no system of human philosophy, has ever stood, and ever shall stand, in sublime simplicity and undecaying strength ; while the winds and the waves of conflicting human opinions roar and dash harmlessly around, and the wrecks of a thousand false systems of philoso phy and religion are strewed along its base. But the religious applications of chemistry do not consist simply in illustrating a passage of Scripture. It abounds with the most beautiful exhibitions of the divine wisdom and be nevolence ; and notwithstanding the ingenious developments by Prout, in his Bridgewater Treatise, and by Fownes in his Prize Essay, I must believe that this field is only just entered, and that most precious gems will be found in almost every part of its wide extent. What admirable skill and benevolence does the doctrine of definite proportions and atomic constitu tion in chemical compounds present! Here we see nature incessantly performing processes, on which organic life and comfort depend, with a practical mathematics as perfect as the theory. And then, how wonderful is the isomeric consti tution, recently discovered, of those proximate principles that form the food of animals and plants ! How beautiful, too, the mode — only recently ascertained — by which this nourish ment is brought within their reach, and introduced into their systems ! See, too, what wonderful benevolence, as well as THE HIGHEST USE OF LEARNING. 37 wisdom, is displayed in the laws and operations of heat, by which its very excess in tropical regions produces, by evapo ration, the paradoxical result of cooling and rendering habi table that burning zone ; and on the other hand, the congela tion and condensation, produced by its absence in frigid regions, renders the atmosphere warmer and the climate habitable. Think, also, how, in the case of water, by an apparent excep tion to a law of nature, just as it enters into a state of con gelation, the great bodies of that liquid in our rivers and lakes are prevented from freezing up in the winter, so that the longest summer would not thaw them out. And finally, what substance in nature is so wonderfully adapted to its manifold and seemingly opposite uses as water ! " Simple though, it seem, Emblem of imbecility itself, As most regard it, yet in fact, the food Of all organic life ; the fruitful source Of power in human arts ; and in the clouds, The storm, the mountain stream, the placid lake, The ocean's roaring and the glacier's sheen, The landscape's frostwork, or its icy gems, Hence springs the beautiful and the sublime. A power, indeed, pervading nature through ; Now moving noiseless through organic tubes, To keep stagnation from the vital frame ; And now the Atlantic dashing to the skies, Or rushing down Niagara's rocky steep, Earth trembling, staggering, underneath the shock : Effects so diverse, opposite, to gain By one mild element, a problem this, No wisdom, short of infinite, could solve." No sciences have furnished so many and so appropriate facts, illustrative of natural theology, as anatomy and physi ology. They have been the great magazine whence writers on that subject have drawn their most effective weapons in 4 38 THE HIGHEST USE OF LEARNING. their war with atheism : but being so fully described in so many treatises, I need not enter into particulars. Compara tive anatomy and physiology, however, of more recent date, have not yet been so extensively employed for religious illus tration as they will be ; although Bell's Bridgewater Treatise upon the hand affords us a foretaste of what may be done. The developments of these sciences are truly marvellous. Who would have believed, for instance, fifty years ago, that such is the mathematical correlation, not only of different parts of an animal, but of parts of different animals, that from a single fragment of the bone of an unknown creature, the skilful anatomist can construct his whole skeleton, and then clothe it with muscles, blood vessels, and nerves, and point out its food, its habits, and its haunts ? Yet this has been done in many instances ; and the subsequent discovery of the whole skeleton has confirmed the accuracy of the principle employed, and the results obtained. What a striking proof of the exist ence and agency of a Being infinitely wise and powerful, to contrive and create the universe ! For, in fact, we find that the correlation of animal structures, so beautifully devel oped by Cuvier, Owen, and others, is but a specific example of the great law of harmony, that links together, by a golden chain, the great and the small, the past, the present, and the future, throughout the universe. The science of physiology, however, has often been looked upon with jealousy by the friends of religion, as leading its votaries to materialism. It would not be strange, indeed, if men, who see such astonishing effects result from exquisite material organization, and who give but little attention to the functions and laws of intellect, should come to think it possi ble that even thought may be only a result of that organiza tion. But the difficulty lies, not in the science, but in these THE HIGHEST USE OF LEARNING. 39 partial views — in that common failing of literary men, to at tempt to group every thing under a favorite science, and ex plain every thing by it. And further, when I find even pro fessedly Christian men defending materialism, and some of its ablest advocates admitting that the soul may be something " immortal, subtle, immaterial, diffused through the brain,"* (I use their very words,) I cannot believe that the views of such men, as to the nature of the soul, differ much in reality from those of the strict immaterialist, although they use different terms. Nor will the practical influence of their opinions, false as they undoubtedly are, when understood in their strict sense, be likely to be very disastrous ; although there is a grosser form of materialism, that is made the basis of a hateful system of atheism. There are two recent offsets from physiology, which have been supposed fraught with influences unfavorable to religion. I refer to phrenology and mesmerism. The first has been thought to favor materialism, and to lessen human responsi bility ; and the latter, to bring miracles into disrepute, and to direct us, for the cure of the body and the soul, to a class of dreaming pretenders, whose responses are about as much to be relied on as those of the oracle of Delphos, the god of Ekron, or the witch of Endor, and whom it is about as impious to consult. The merits of these new branches of science, this is not the proper occasion to discuss ; nor is it easy as yet to ascertain definitely what principles in them are settled. But admitting their pretensions, the first seems to -leave the question of materialism just where it found it ; since it is as easy to see how an immaterial soul should act through a hundred organs as through one. Nor does it seem to me more difficult, on natural principles, to see how the mind may * Elliotson's Physiology, p. 39. 40 THE HIGHEST USE OF LEARNING. act at a distance, through the undulations of a mesmeric me dium, than to see how light and heat are transmitted by the waves of a luminiferous ether. On the other hand, if physi ology and phrenology tend to materialism, certainly mesmer ism tends even more decidedly to immaterialism ; as the con version of several distinguished materialists will testify. It does, also, open to the Christian (admitting its statements to be true) most interesting glimpses of the mode in which the mind may act when freed from flesh and blood, and clothed with a spiritual body. Indeed, I doubt not that, in regard both to phrenology and mesmerism, the general principle will prove true, that the more ominous of evil any branch of knowledge seems to be in its incipient state, the more prolific it will ulti mately become in illustrations favorable both to morality and religion. The wide dominions of natural history, embracing zoology, botany, and mineralogy, the theologist has ever found crowded with demonstrations of the divine existence, and of God's prov idential care and government ; and every new province that has been explored by the naturalist only serves to enlarge our conceptions of the Creator's works, and to impress us more deeply with their unity and perfection. These new conquests in unknown regions have been astonishingly numer ous within the last half century ; but in the direction pointed out by the microscope they have been most marvellous. The existence of animals too minute to be seen by the naked eye has, indeed, long been known ; but it was not till the re searches of Ehrenberg that any just conceptions of their in finite number and indefinite minuteness were entertained. We now know that nine millions of some of these animalcula may live in a space not larger than a mustard seed, and that their numbers are many million times greater than that of all THE HIGHEST USE OF LEARNING. 41 other animals on the globe. Indeed, the microscope has laid open a field into the infinitesimal forms of organic and inor ganic nature quite as boundless, both in number and extent, as the telescope discloses in infinite space. Nor can we find any limits in the one direction more than the other ; and thus does the microscope, in the same manner as the telescope, prodigiously enlarge our conceptions of the perfections of the infinite Author of the universe. These researches have cast not a little light upon a certain hypothesis, that has been, in one form or another, often thrown before the world since the days of Democritus and Epicurus, usually for the purpose of sustaining a system of atheism. It supposes an inherent power in nature, capable of producing plants and animals without parentage, by an imagined vital force, essential to some forms of matter. The ancient phi losophers imputed these effects to a " fortuitous concourse of atoms." In modern times this general statement has been made more definite by Lamarck, Geoffroy St. Hilaire, Bory St. Vincent, and others, who suppose that Nature — in their vocabulary sometimes dignified by the title of Deity, but still unintelligent, and merely instrumental — gives origin only to " monads," or " rough draughts " of organic beings ; and that these, by " an inherent tendency to improvement," and " the force of external circumstances," become animals of higher and higher organization ; until at last the orang-outang aban doned his quadrupedal condition, and stood erect as man, with all his lofty powers of intellect. Before the invention of the microscope, a multitude of insects and worms were thought to have this equivocal origin, and to pass through these trans mutations — an example of which every Latin scholar will recollect in the directions of Virgil for the production of a swarm of bees out of the carcass of an animal. But as op- 4* 42 THE HIGHEST USE OF LEARNING. tical instruments have been improved, and observations have become more acute, the origin of nearly every animal visible to the naked eye has been found to be by ordinary genera- tion. The advocates of the spontaneous production of organic beings, however, still clung to the animalcula and the entozoa. But it is now clearly demonstrated that all the former class have been derived from parents; and that more abundant means are provided for their reproduction than for any of the higher tribes of animals. The same is true of the entozoa — a single individual of which is capable of producing more than sixty millions of progeny ; and it would be very strange for nature to take such extraordinary pains for their propaga tion if it might have been accomplished spontaneously. Not a single certain example, indeed, of the spontaneous produc tion of living beings can be adduced ; and if there are a few cases where parentage has not been yet discovered, the past history of the subject makes it almost certain that it needs only more perfect instruments, or more extended observa tions, to prove that the same great law of reproduction em braces all animated nature. And as to the transmutation of species, geology has shown that it has never taken place ; while physiology demonstrates that species are permanent, and can never be transmuted. The individual does, indeed, pass through different stages of development, some of which resemble the perfect forms of species inferior to it in the organic scale. But the limits of these developments are fixed for each species ; nor is there a single known instance in which an individual has been able to stop at any particular stage, and thus become another species. In view of these facts, it is not strange that most of the men best qualified to judge on such a subject — as for instance, Owen, the ablest of comparative anatomists ; Ehrenberg, the THE HIGHEST USE OF LEARNING. 43 first of microscopists ; and Muller, most eminent in physi- ol°gy — should reject these hypotheses of spontaneous gen eration and transmutation. Nevertheless, the unusual interest which has been manifested by the recent work entitled Ves tiges of the Natural History of the Creation — wherein these hypotheses, as well as the nebular hypothesis, are ingeniously defended, and that, too, without denying the original interven tion of a divine Power in nature — show us that a long-drawn contest is yet before naturalists on these subjects, ere these fancies shall be forced into that extramundane receptacle of things abortive and unaccomplished, described by Milton as " a limbo large and wide," on the back side of the moon. And yet, my conviction is that this contest will not have so important a bearing on the cause of religion as some theol- ogists imagine. For, even though these hypotheses should be established, an intelligent, spiritual; infinite Deity is quite as necessary to account for existing nature as on the more com mon theory, which supposes the universe commanded from nothing at once in a perfect state. Indeed, to endow the par ticles of matter with the power to form exquisite organic com pounds, just at the moment when circumstances are best adapted to their existence, and then to become animated, nay, endowed with instincts, and with lofty intellects, — all which results the advocates of these hypotheses must impute to the laws impressed upon originally brute matter, — such effects, I say, demand infinite wisdom, power, and benevolence even more imperatively than the common theories of creation. I doubt not that in general these hypotheses have been adopted to sustain atheistic opinions, or to remove the Deity away from his works. But unbiased philosophy sees that they utterly fail to accomplish either of these objects. And I confess that I reject them more because they have no solid evidence in 44 THE HIGHEST USE OF LEARNING. their favor than because I fear that they will ultimately be of much injury to religion ; especially so long as such works as Whewell's Indications of the Creator are within the reach of the scholar. The religious bearings of geology alone remain to be no ticed. And no science, except perhaps astronomy, has excited so much alarm as this for its supposed irreligious tendencies. But so soon as theologians discovered that while the Mosaic chronology fixes the date of man's creation, it leaves the an tiquity of the globe unsettled, and, therefore, a fit subject for philosophical examination, they began to see that this science might be made to shed much light upon religion. Indeed, it already excels every other science in the importance of its religious applications ; and notwithstanding the noble begin nings by Dr. Buckland, Dr. J. Pye Smith, Dr. Chalmers, and others, the work of development is but just begun. Would that my time and the reader's patience might permit us to take a leisurely survey of this interesting field. But a glance must suffice. To say nothing of the illustrations of the meaning of re vealed truth derived from this science, — of collision between them there is certainly none, — it furnishes us, in the first place, with a new argument for the existence of a Deity. This argument rests upon three leading facts of the science independent of one another ; so that we may doubt or deny one or two of them, and yet not reject the argument. The first is, that there was a period when no animals or plants existed on the globe, and, therefore, an epoch when they were created ; which must have required a Being of infinite perfections. The second is, that there have been on the globe several nearly entire extinctions and renewals of or ganic life, each of which demands the agency of such a THE HIGHEST USE OF LEARNING. 45 Being. The third is, that man was only recently created — almost the last of the animals ; and since he is at the head of creation, nothing in nature has demanded a higher exercise of wisdom and power than his production ; and, therefore, it must have required a Deity. It is obvious that these same facts prove clearly the non- eternity of the present condition of the globe ; and even though we admit the ancient doctrine of matter's eternity, yet its most important modifications, requiring a Deity no less than its creation, must have been produced in time, and this conclusion is all that is essential to theism. And thus geol ogy, which has been supposed to favor the idea of the world's eternity, is the only science, as Dr. Chalmers has splendidly shown, that can prove its non-eternity. These same facts, and others that might be named, demon strate the occasional interference of the Deity with the settled order of nature : in other words, they show us splendid mir acles of creation. And thus is all presumption against the miracles of revelation done away ; and also all objections against special providence and special answers to prayer. This science, too, opens to us views into the arcana of past duration, as deep and illimitable as astronomy does into the arcana of space ; and there is made to pass before us a splen- flid panorama of the vast and varied plans of Jehovah ; while chemical change is disclosed to us as the great conservative and controlling principle of the universe, superior even to the laws of gravitation. The unity of the divine plans is also ex hibited to us by the records of this science, on a far wider scale than the existing economy of nature can show. And, finally, it brings before us a great number of new and pecu liar proofs of divine benevolence, that throw new glory over this attribute of the Deity ; derived, as they are, from facts 46 THE HIGHEST USE OF LEARNING. heretofore supposed to prove divine malevolence, or at least vindictive justice. We have now taken a glance at the entire and vast circle of human learning. And is not every mind forced irresisti bly to the conclusion, that every branch was originally linked by a golden chain to the throne of God, and that the noblest use to which they can be consecrated, and for which they were destined, is to illustrate his perfections and to display his glory ? If so, let me conclude my too protracted remarks by a few inferences. In the first place, what a monstrous perversion and misap prehension of learning it is, to consider it as hostile to religion. It is not difficult to explain how a Christian, who is very ignorant, and who learns that literary men are often sceptical, should distrust the influence of learning upon religion ; nor how a mere smatterer in science, himself sceptical, should flatter himself that his great learning made him so. But how strange that any talented and well-informed man, be he Chris tian or infidel, should not see that all science and a large part of literature are " But elder Scripture writ by God's own hand ! " It must be the strongest prejudice, or the most decided ha tred to religion, which can suppose that one work of the sam% infinitely perfect God should oppose another ; for, in fact, learning and religion are only different shoots from the same parent stock ; and if their fruit be of opposite qualities, it must be because man has grafted upon one or the other the apples of Sodom. To set learning against religion is as un natural as to array brother against brother on the field of combat. We see, secondly, that those engaged in directly promoting THE HIGHEST USE OF LEARNING. 47 religion, and those devoted to learning, ought to look upon each other as laboring in a common cause. If their labors are such as they should be, they will help each other ; and, therefore, they ought to rejoice in each other's success. For though a new branch of learning but half understood may sometimes put on an aspect threatening to religion, we need never fear but the final result will be a new support to religion ; and, therefore, the religious man should dismiss all fears and jealousies in respect to sound learning ; while, on the other hand, every increase of true religion has an auspicious bearing upon the cause of learning. We see, thirdly, that the preacher of the gospel may con sistently devote himself to the work of instructing the young in literature and science. For, in the first place, he need not by such a change necessarily abandon the direct preaching of the gospel occasionally. In the second place, by faithful in struction in learning,. he may greatly promote the cause of religion, and train up many, perhaps, to exert a still wider influence in its favor. Finally, how much better that such a man should use science and literature legitimately for the support of religion, than that they should be perverted by a sceptical teacher to undermine it ! In spite of these reasons, however, we are frequently told that for a minister of the gospel to become a teacher of human learning, is to abandon his high calling, and forfeit his solemn vows ; as indeed he may do, by engaging in such pursuits from merely secular motives. In the fourth place, we see that the more eminent a man is for learning, the more eminent he should be for personal piety. Why, indeed, should not the latter increase in his heart, as the former does in his intellect ? For every new accession of knowledge is but a development of some attribute or plan of I 48 THE HIGHEST USE OF LEARNING. the Deity. The entire field of human learning all rightfully belongs to religion, and should be regarded by the Christian scholar as consecrated ground. The farther he advances in it, the more does he see of the Deity ; and as he returns from communion with Nature in the very holy of holies of her temple, he ought, like Moses from the holy mount, to show a radiant glory on his countenance. In the fifth place, what importance does the subject give to the pursuits of learning, and the institutions of learning ! If knowledge is power in secular matters, it is no less so in religion. I know that a higher power is essential to the suc cess of the latter. But I know, too, that religion without learning almost infallibly degenerates into fanaticism or dead formalism ; and indeed, at this day, true religion will not flour ish except in connection with learning ; and, therefore, al most every denomination is now striving to found and sustain literary seminaries. Nor is their importance yet duly esti mated, because but few realize how indispensable is their agency in promoting the noblest of all objects, the salvation of men ; and, therefore, in our land at least, with a few ex ceptions, their foundations are too narrow, and the super structure too frail. In the sixth place, how justly are those honored, and how wide an influence do they exert, who found and endow liter ary institutions from religidbs motives ! They may be charged with unhallowed ambition, by men who think only of the secular influence of these institutions. But he who considers what is the highest use of learning, and how immense will be the influence of a well-endowed semi nary upon the cause of religion, cannot but look upon such bequests as the noblest of charities ; especially when he re members how much more enduring is that influence than THE HIGHEST USE OF LEARNING. 49 when money is given to most other benevolent objects. What names stand higher on the Christian's roll of fame than those of Harvard, and Yale, and Dartmouth, and Williams, and Brown ? And through how many coming centuries of our country's history will their example stimulate others to go and do likewise ! By liberal bequests to literary institutions while yet feeble and struggling for existence, their names have become inseparably fixed upon them, where they will remain long after the pyramids of Egypt shall be crumbled into dust. In what other way could they have exerted so de sirable, extensive, and enduring an influence upon the world? In the seventh place, what a noble yet immense work lies before Christian scholars, viz., to make all learning subser vient to its highest purpose ! Sadly have many branches been perverted, and strong is still the disposition to divert all learning from its noblest use. To arrest this downward tendency, and to bring back all lit erature and all science to the service of religion, is an object of the highest ambition, adapted to call forth the strongest efforts of every Christian scholar. And let all such take courage. For religion is the natural home of all branches of learning ; and though some of the sisterhood have been seduced into the service of sin and the world, and have for gotten their paternity, yet when reminded of their sacred origin, gladly will they return to the paternal hearth, and pile richer gifts upon the altar, where they presented their earliest offerings. In the eighth place, we learn how important it is that every literary institution should make the promotion of religion the leading object of its system of instruction. Other objects of subordinate importance it may ami ought to endeavor to accomplish ; but to make these the chief things 5 50 THE HIGHEST USE OF LEARNING. aimed at, while religion is thrust into the background, is as if a man should build an elegant mansion for the sake of im proving the landscape, and with no intention of living in it ; or as if a community should erect a church for the sake of holding town meetings and political caucuses in it, and hearing lyceum lectures, with no intention of using it as a place of worship, except perhaps occasionally. There is, indeed, a great cry about excluding sectarianism from our literary institutions, and throwing them open to per sons of all religious opinions. Now, in this country, where we have no established church, it is difficult to define a secta rian, unless it be a man who differs from us in religious sen timents. So that in fact, with the exception of a few, who have no opinions or care on this subject, we are all sectari ans ; and to exclude sectarianism from a literary institution is to exclude all religion from it. And such is usually the re sult, when it attempts so to trim its course as to suit all par ties. But really, of all kinds of intolerance, that is the worst which is furious for toleration, and that the worst kind of sectarianism which is fierce for irreligion. The only true liberal and manly course for an institution to adopt, is, openly to avow its creed, and not to disguise its desire to have all the youth adopt it who resort thither ; while at the same time it uses no other means but argument and example to convert them, nor permits their religious opinions, whatever they may be, to have any influence in awarding literary honors. In this respect the motto of the ancient Tyrian queen should be adopted by every teacher : — " Tros Tyriusve nullo discrimine mini agetur." Such a course does, indeed, make the institution sectarian , that is, it shows a preference for some particular system of THE HIGHEST USE OF LEARNING. 51 religion. But it is an honest course, and the only honest one that can be taken. For if an institution professes to regard all religious opinions with equal favor, who can avoid the sus picion that it is either a stratagem for introducing some un popular system, or that it indicates an almost universal scep ticism on the subject ? Indeed, how can a man, who has any just sense of religious obligation, consent to be placed in cir cumstances where he cannot recommend openly those reli gious views which he deems essential to salvation ? In the ninth place, we see that a professorship of natural v theology is an appropriate one in a college. The main business of such a professor is to go over the same ground as we have now glanced at, and to trace out the bearing of all literature and all science upon religion. And if this be, indeed, the most important use of learning, why should it be left unprovided for ? or depend upon the voluntary efforts of the different instructors, whose hands are already quite full ? I make these remarks, because such a professor ship is unusual in our colleges; and I have feared that the one with which I have been recently honored may seem to have been got up for the occasion, to eke out a deficiency of titles. But it is not so ; and it is proper to say, that I have in v fact, for the last ten years, attempted to perform the duties of such a professorship. Finally, to the principle which I have endeavored to prove, we owe the establishment of many modern literary and sci entific institutions, and eminently of that within whose walls we are assembled. By recurring to the history of the origin of some of the ¦> most distinguished scientific societies and literary institutions of Europe, it will appear that one of the leading objects v which their illustrious founders had in view, was to extend a 52 THE HIGHEST USE OF LEARNING. knowledge of the Christian religion, along with the arts and sciences, to remote and barbarous nations, particularly those of the south-eastern Asia. Among the institutions thus origi nating were the Royal Society of London, the French Acad- emy, the Berlin Academy, the Academia Naturae Curiosorum, the University of Halle, and the Institutions of Franke at Halle ; and among the distinguished men who have labored in this work we find the names of Boyle, Montucla, Leibnitz, Wolf, and Humboldt.* I fear, indeed, that this object has been often lost sight of by these institutions ; but their origin furnishes us at least with the testimony of most able and com petent witnesses to the truth of the position which I have now vindicated and illustrated, as to the highest use of learning. But to come nearer home : we shall see that this institution originated in a deep conviction of this same truth in the minds of those noble-hearted men, who, in faith and prayer, laid the foundations on which we are called upon to build. The very first paragraph of the constitution of what they then called a charity institution contains it ; and in the first article it is said, " In contemplating the felicitous state of society which is predicted in the Scriptures of truth, and the rapid approach of such a state, which the auspices of the present day clearly indicate, and desiring to add our feeble efforts to the various exertions of the Christian community for effecting so glorious an event, — we have associated together for the express purpose of founding an institution on the gen uine principles of charity and benevolence, for the instruction of youth in all the branches of literature and science usually taught in colleges." Here we see no other reason assigned for founding the institution but a wish to promote the cause of religion ; as if no other benefits to result from it were * Oratio in Academia Fridericiana Halensi, &c. habita ab. D. J. S. C, Schweigger, p. 4, Halle, 1834. THE HIGHEST USE OF LEARNING. 53 worth naming. Let this fact never be forgotten by those who manage and instruct in this college. God forbid that the time should ever come when any instructor here shall be ashamed, or backward, to acknowledge that the advancement of pure religion — even the Christian religion — is the grand object for which he labors and makes sacrifices.* Let us never forget, that promotion cometh neither from the east nor the west, nor from the south. But God is Judge. He setteth up one, and pulteth down another. How easy for him to blast the fairest schemes, and to prosper the weak and the trembling ! Nor let our confidence in him, or in the prosperity of this institution, be shaken, because it has been called to pass through straits, and other conflicts may still await it. We believe that these storms in its youth are in tended, by a wise Providence, only to make its roots strike deeper, and to give its trunk greater strength, and its branches wider extension in its maturity. Only let faith hold on firm ly to the principle, that God will assuredly crown with suc cess every sincere effort to bind the wreath of learning around the brow of Religion, and cheerfully and resolutely shall we consecrate ourselves to the great work of sustaining and ad vancing this institution ; and though we shall not be allowed to labor long here, or elsewhere, yet while we live, and when we die, we may confidently utter in behalf of its pupils, its guardians, and all its future interests, the prayer of a hea then, with a Christian meaning and a Christian spirit : — w Dii probos mores docilii juventse, Dii senectuti placida? quietera Romulse genti date remque prolemque Et decus omne ! " * Several pages relating to the college, its discouragements and encour agements, are here omitted. 5* THE RELATIONS AND MUTUAL DUTIES BETWEEN THE PHILOSOPHER AND THE THEOLOGIAN. The history of the manner in which philosophy has been treated by theologians, and theology by philosophers, is very instructive and suggestive. Some of the former have taken philosophy into a close and most cordial embrace, and allowed it to modify, and even form a part of the foundation of their whole system of doctrines ; and, as you looked at the stately pile, you could not be certain whether the human or the divine had most to do in its erection. Another class have been as jealous of philosophy as if its touch were infectious, and its infection death ; and it would seem as if they took special pains to make their professedly biblical system of truth look as distorted and angular as possi ble, lest they should be suspected of having used the mould ing and the dressing tool of reason to give it form and sym metry. On the other hand, the tendency among philosophers has been to rank theology below the other sciences. Some of them have maintained that the two departments are quite in dependent of each other, and that the question of agreement between them is one with which they are not concerned. Their business is to discover the truths of science, and to leave theology to take care of itself. Others admit the desirableness (54) RELATIONS OF THE PHILOSOPHER AND THEOLOGIAN. 55 of a reconciliation, but are quite jealous of any claims, on the part of revelation, to superior authority. But though thus diverse and conflicting have been the views of theologians and philosophers respecting their mutual rela tions and duties, yet the history of the connection or opposi tion between theological and philosophical systems has consti tuted no small part of the annals of the church. And from that history we learn two things : first, that there is an im portant connection, and consequently there are important duties, between the theologian and the philosopher ; and secondly, that these relations and duties have been, and still are, sadly misunderstood or neglected. No code of principles, defining those relations and duties, has yet been elaborated ; and hence these classes have often treated each other like the partisans in a border warfare ; and prejudice and illiberality have been the impelling forces, rather than Christianity or philosophy. These remarks will probably lead you, gentlemen of the society at whose request I stand here to-day, and other re spected auditors, to anticipate a discussion on the Relations between the Theologian and Philosopher. Such is my inten tion ; or, to state the subject more specifically, I propose to enucleate and examine the principles which should regulate the intercourse and feelings of these two classes of society. I employ the term philosophy in its broadest signification embracing all science, physical, intellectual, and moral. Yet for special reasons, I shall rest my eye chiefly upon, and de rive my illustration from, inductive or physical science. For in the first place, circumstances beyond my control, and con nected chiefly with health, have turned my attention main ly to this department of philosophy ; secondly, the claims and bearings of moral and intellectual philosophy, oftener, and 56 MUTUAL RELATIONS BETWEEN with a power which it would be in vain for me to aspire after, have been brought before you. And finally and especially, a deepening interest seems to be gathering around physical sci ence, both as a rich repository of arguments for, and illustra tions of, religion, and a magazine of missiles to hurl against it. In attempting to discuss such a subject, it is gratifying to find one's self addressing the members of an institution where the freest and the fullest investigation of all truth is encour aged, and where evidence, not authority, is the test by which every principle is tried ; an institution, which, while it boldly and honestly maintains its own views of religious truth, exer cises the charity of the gospel towards those who reject them, and expects to convince them only by manly argument. It is not flattery, but justice only, to say that it is eminently by the labors of the distinguished men who have presided here, fol lowing in the steps of Edwards, Hopkins, Bellamy, and Em mons, that evangelical Christianity has assumed such a shape as to render its reconciliation with philosophy possible. Mon uments evincing the truth of this position rise all around me. The Nestor of biblical philology is not, indeed, here to-day ; but his works are, and they evince how much he has done to unfold the true meaning of the Word of God, and how fear lessly, yet impartially, he sought for the truth ; never inquir ing, while engaged in his investigations, whether the results would favor this or that theological system, but whether they brought out the true mind of the Spirit. And he well knew that if that could once be surely ascertained, it would be found in entire harmony with all other. The Nestor of theology is still here ; and so are his works ; especially the last and greatest one, which gives us results of nearly half a century's careful examination of systematic theology. Those results, presented in language of such simplicity as only true greatness THE PHILOSOPHER AND THEOLOGIAN. 57 and conscious strength know how to use, and with a calmness and fairness of reasoning which only a perfect knowledge of the subject, and a thorough conviction of its truth, could em ploy, stand up before my eye, as one of the noblest monu ments which human skill and piety can raise to God's glory and man's good. I mean not that the work is perfect, nor that keen criticism, nor that the large-pupiled eye of prejudice and envy cannot find weak spots in it ; nor that I should not myself dissent from some minor points defended in it. But as an American, and a Christian, I rejoice, and bless God that the venerable author has been spared to place the top stone on this column of eternal truth, which I predict shall abide fresh and strong, when the Washington Monument and the Bunker Hill column shall become only crumbling mounds. As an American, and a Christian too, when lately on a for eign shore, it was gratifying, and I hope to some better feel ings than mere national pride, to be able to point to a certain Bibliotheca, whose pages, each trimester, open, to the scholar and the Christian, productions which combine philosophy more profound with biblical analysis more accurate than any other evangelical periodical in the English language with which I am acquainted. Let this -testimony, too, be regarded only as an act of justice, and not of flattery. This allusion to the Bibliotheca reminds us — as indeed almost every thing else does to-day — of another strong pillar of this institution, whom Providence has recently smitten down.* Nor is it this Seminary alone that feels the stroke. When such a man falls, it brings a cloud over the whole re public of letters, and creates a wide blank, especially among the cultivators of sacred literature. It will be deeply felt even on the other side of the Atlantic, where his able works * Professor B. B. Edwards. 58 MUTUAL RELATIONS BETWEEN have been long known and appreciated. This is not the place to give his life, or his eulogy, which has already been done in a most satisfactory manner. But there is one trait of his writings and his character which it is proper I should notice. Though devoting himself chiefly to classical and biblical litera ture, yet his active and scrutinizing mind was not satisfied till he had mastered the leading principles of almost all branches of learning ; and he kept his eye open to the progress of secular as well as sacred literature and philosophy. His accurate judgment appreciated full well the importance of bringing all branches of human learning into harmony ; for he well knew that there can be no real discrepancy between one kind of truth and another. Hence, when philosophy and revelation were in apparent collision, he knew that the one, or the other, or both, were not fully understood ; and therefore he wel comed every new ray of light which literature and science, history and observation, might cast upon the Bible, and the Bible might cast upon philosophy. In a word, he had those enlarged and liberal views, in regard to the relations and mutual duties of the theologian and the philosopher, which made him, in this respect, a model man. From those narrow views and prejudices — the odium theologicum — which too often result from exclusive attention to one department of knowledge, he was remarkably free. He never substituted denunciation for argument ; not because he was indifferent to the truth, but because he had so much confidence in its naked power and ultimate triumph. It is such men who are wanted in the ranks of theology, to command the respect of philoso phers and the confidence of Christians. O Andover ! how deep the wound inflicted upon thee in his removal ! " Hei mihi ! quantum Preesidium, Ausonia, et quantum tu perdis, Iule ! " THE PHILOSOPHER AND THEOLOGIAN. 59 But thanks be to God, that he was spared so long as to be able to make an abiding impress here. Nay, the cause of learning, of education, of religion throughout the land, shall long feel the influence of his labors ; and other lands shall share in the rich legacy which he has left. And now, before an audienee trained by such men, and under the influence of such principles, I feel confident that I shall be heard with candor, and, I hope, with sympathy, while I attempt to ascertain and enucleate the principles that should form the mutual creed of the theologian and the philosopher. The first means which I shall employ for determining this platform of principles consists in an appeal to reason and Scripture. We need, however, as a basis for our inquiries, to define the limits and the functions of philosophy and of theology. The first searches out and classifies the laws of nature ; the second presents the principles of religion, natural and re vealed, in a scientific or systematic form. Theology, there fore, has a right to employ whatever facts and reasonings it can find in philosophy, illustrative of religion. The principles of reasoning, too, are the same as in philosophy. But it pos sesses, in addition, an infallible standard of appeal for all subjects that are above reason. The object of philosophy is to explain the phenomena of nature, mental, moral, and mate rial ; that of theology is exclusively to defend and enforce the moral relations of the universe. Hence the two subjects are almost entirely distinct in their aim. The only point where they pursue the same track is in the department of moral philosophy, which has derived from revealed theology the only true foundation on which to build, and that is, the character of man as a fallen being. Incidentally, however, the two branches treat of the same subject ; as, for instance, 60 MUTUAL RELATIONS BETWEEN the creation, the deluge, and the destruction of the world and its organic races. Bat since revelation does not pretend to teach science, nor even to use language in its strictly scien tific sense, we ought to expect, in such cases, only that there shall be no real, although there may be an apparent, discre pancy between the two records. Thus distinct, in nature and in function, are these two great departments of human knowledge. Both do, indeed, connect with the same Infinite Source of all knowledge ; but they oc cupy separate and clearly defined provinces, and those at work in one field need not encroach upon, or despise and overlook, those in the other. Providence intended that they should be mutual helps, and mutually deferential. That the ology has a vast preeminence, does not justify an undervalua tion of philosophy, as if it were of no consequence. This course of remark leads naturally to the attempt to lay down as the first article of the mutual creed of the philosopher and the theologian, this principle : That on the question of authority, while science should receive all the credit which its various degrees of evidence deserve, theology has a higher claim to any branch of knowledge not strictly demonstrative. A mathematical demonstration no sane mind can resist ; and little less certain are the physico-mathematical sciences. But where scientific conclusions depend only upon probable evi dence, observation, and experiment, for example, there is some room for mistake and false inference. And is it not reasonable to maintain that theology has a higher claim to credence than the probabilities of any single science ? For the evidences of its truth, drawn from so many sources, and so diverse, must be considered as outweighing the evidence of any single science dependent upon experiment or observation. If, therefore, a direct collision could be made out between THE PHILOSOPHER AND THEOLOGIAN. 61 such a science and religion, and we were compelled to choose between the two, theology must carry the day. I make this supposition, not because such an alternative ever has occurred, or ever will occur, but merely to show what are the relative claims to deference of theology and probable science. Not unfrequently, where only an apparent discrepancy has manifested itself between revelation and some yet imperfect science, the self-confident sceptic considers the fate of Christianity as decided. But that is only a flippant phi losophy which will not rank revealed truth above any single science founded upon probable evidence. Not only does the- ^ ology stand above all other sciences in the importance and dignity of its principles, but in the authority with which it speaks ; for it rests mainly on inspired testimony. On the other hand, however, not a few divines demand for theology, not only superior authority, but will allow none at all to science, in matters of religion. " We have," say they, " an inspired record, and its declara tions are not to be set aside, or modified in the least, by any pretended discoveries or theories of blind and perverted hu man reason. God has spoken, who cannot lie, and his Word is to be received implicitly, whatever may become of the sup posed facts or conclusions of weak and ignorant man." Such reasoning overlooks one important principle. AU will agree that when we know certainly what God has revealed, we are to receive it without modification. But he has re vealed himself through human language, and given us no in spired interpreters. We are to ascertain the meaning of Scripture essentially as we do that of any other writings. Accordingly we do not hesitate to resort to philosophy and history, as guides in our exegesis. Nor do we refuse the light that comes to us from the deciphered hjeroglyphics of 62 MUTUAL RELATIONS BETWEEN Egypt, and the disinterred relics of Nineveh. Why, then, should not the testimony of science be employed to elucidate the meaning of Scripture, especially when it opens archives a thousand times more ancient, and no less distinct, than those of Egypt and Nineveh ? No reasonable philosopher asks that science should be allowed to set aside or modify any thing which God hath spoken, but only that it should be employed to ascertain what he has spoken ; for without the aid of sci ence men have sometimes been unable to understand aright the language of Scripture — as in the rising and the setting of the sun, and the immobility of the earth, described in the Bible. Before astronomy had ascertained the earth's true diurnal and annual motions, the scriptural statements were not, and could not be, understood aright. And the same may be true in respect to phenomena dependent upon other sciences. A second principle of this creed — if it be not too obvious, and too generally acknowledged, to require a formal statement — takes the ground, that as a means of moral reformation and regulation of human affairs philosophy has little power, and is not to be brought into comparison with theology. Both reason and experience have given so many striking illustra tions of this truth that it seems strange any should wish to repeat the experiment. But it is done every few years ; nay, at all times we find men zealous in advocating some new phil osophic scheme for reforming and perfecting human society, whose essential element is something different from, the meth od pointed out in the Bible. The new system may have some principle in common with Christianity ; but the author of it relies rather on the differences which he has superadded than on the agreement. Yet what multitudes of such schemes, after an ephemeral excitement, become the byword of the world, THE PHILOSOPHER AND THEOLOGIAN. 63 and pass silently into that oblivious receptacle of things, "Abor tive, monstrous, or unkindly mixed," described by Milton ! " All these, upwhirled aloft, Flew o'er the back side of the world, far off, Into a limbo large and wide, since called The Paradise of Fools : — to few unknown Long after." — A third important principle, which reason teaches as appro priate for this mutual creed, is, that entire harmony will be the final result of all researches in philosophy and religion. It is strange how any other view of the matter can be enter tained by men who profess to believe that the God of nature is the God of revelation. For what are nature and revela tion but different developments of one great system, emanat ing from the same infinite Mind ? Yet not a few theologians look upon science as a dangerous ally of revelation, and main tain that we are not to seek for harmony between them. " The Bible," say they, " was given for our infallible guide, and it is of little consequence whether its teachings coincide with those of philosophy. The history of the church shows us that the two have always been in collision, and it is a dangerous enterprise for the religious man to labor for their reconcil iation. Let him follow the teachings of revelation implicitly, nor suffer any of its statements to be modified by the 'pre tended facts or theoretical deductions of science." Does this seem to any to be a caricature ? Take, then, the words of a distinguished American divine. " We are not a little alarmed," says he, " at the tendency of the age to re duce the great facts narrated in the Bible to the standard of natural science." " Human, science is a changing and rest less thing. It is well that it is so." , 64 MUTUAL RELATIONS BETWEEN On the other hand, not a few scientific men, although pro- fessing respect for the Bible, and faith in it, yet feel as if its statements should have no weight, even upon any matter of fact which comes under the cognizance of philosophy. Sci ence, it is thought, has its own appropriate evidences, which must be admitted, whatever else goes against it. The Bible was not given to teach science, and therefore it was never intended to be authoritative in such matters. Now, if these two classes of men were to lay it down as a settled principle that all science and all religion are certain ultimately to harmonize throughout, it would remove this mutual jealousy and distrust ; nor would the parties be dis posed to stand aloof from each other, and to treat one another as enemies. If they are ultimately to be entirely one, then they are essentially so now, and all discrepancy is apparent only. Therefore should the philosopher and the theologian feel as if they were brothers, whose business it is, in mutual good will, to elucidate and bring into harmony different por tions of the same eternal truth. Another article of this mutual creed should be, that scien tific men may have the freest and the fullest liberty of inves tigation. They have not always had it. " We remember," says Melville, " how, in darker days, ecclesiastics set them selves against philosophers, who were investigating the mo tions of the heavenly bodies, apprehensive that the new the ories were at variance with the Bible, and therefore resolved to denounce them as heresies, and stop their spread by per secution." Open persecution is unpopular now ; but I fear that a remnant of the same feelings still lingers in some minds. They will not say directly to the scientific man, " Abstain from your researches, for they seem to threaten injury to religion," but their fears of some disastrous influence make THE PHILOSOPHER AND THEOLOGIAN. 65 them jealous of the man, and fearful that his scientific con clusions may lead himself and others astray ; and hence they withdraw their confidence from him, and thus take the most effectual way to alienate and make a sensitive mind sceptical. But how narrow are such views ! and how idle the fear of collision between science and revelation ! How much more noble and truly Christian are the sentiments of Dr. Pye Smith ! " Only let the investigation be sufficient, and the induction honest ; let observation take its farthest flight ; let experiment penetrate into all the recesses of nature ; let the veil of ages be lifted up from all that has hitherto been unknown, if such a course were possible — religion need not fear ; Christianity is , secure, and true science will always pay homage to the divine Creator and Sovereign, of whom, and through whom, and to whom, are all things, and unto whom be glory forever.'''' The difference in the character of the language of science and that frequently employed in religion suggests a fifth article of the supposed platform. Different principles of interpreta tion, to some extent, are demanded in the two departments. True science employs terms that are precise, definite, literal, with scarcely more than one meaning, and adapted only to cultivated- minds. Religion, especially the Bible, makes use of language that is indefinite, loose, and multiform in signifi cation, often highly figurative, and adapted, not only to the popular mind, but to men in an early and rude state of soci ety. Science, for instance, could not, as the Bible can and does, represent the work of creation in one chapter as occu pying six days, and in the next chapter as completed in one day. It could not, like the Bible, speak of the sun's rising and setting, and of the earth's immobility. Meteorology could not describe the concave above our heads as a solid expanse, having windows or openings for the rain to pass from the 6* 66 MUTUAL RELATIONS BETWEEN clouds beyond. Nor could physiology represent the bones to be the seat of pain, or psychology refer intellectual operations to the region of the kidneys. Neither could systematic the ology in one place represent God as having repented that he had made man, and in another exhibit him as without vari ableness or shadow of turning. But all this can the Bible do in perfect consistency with its infallible inspiration, because it was the language of common life ; and common sense can interpret it, so that every suspicion of self-contradiction shall vanish. Indeed, had its language been strictly scientific, it might have formed a good text book in philosophy, but it would have been a poor guide to salvation. Yet the attempt to force the language of the Bible into the strait jacket of science has been prolific of mistakes and errors. Another principle, which maintains that the Bible has an ticipated some scientific discoveries, should be settled and form a part of this mutual creed. In my view it should be settled in the negative. For if we admit that one modern discovery can be found in the fSible, how can we vindicate that book in those numerous cases where it speaks of natural phenomena in accordance with the monstrously absurd no tions which prevailed among those to whom it was originally addressed ? If it describes the science of the nineteenth cen tury in one instance, why not in all ? But admit that it was foreign to the object of revelation to teach science, and we can see why its descriptions of natural things accord with optical, but not physical, truth ; and, then, there is no diffi culty in enucleating the true meaning of the sacred writers. Interpreted by such a principle, we should not conclude that Job meant to reveal the Copernican system because he speaks of the earth as hanging upon nothing ; especially as in an other place he refers to the pillars on which the earth rests. THE PHILOSOPHER AND THEOLOGIAN. 67 But both phrases are quite natural and proper for one of the most allegorical books of the Bible when regarded as vivid poetical images. The grand distinction between the Bible and all other professed revelations is, not that it has anticipated scientific discoveries, but that there is nothing in its statements which those discoveries contradict or invalidate. Often has the sceptic announced such discrepancies; but, in the end, the Bible has always been shown consistent with itself and with science. Now, this is true of no other professedly in spired books. The Koran and the Vedas are often in direct "" collision with astronomy, geology, anatomy, and physiology ; and when you have proved them false in science you have destroyed their authority in religion. Proudly above them all stands the Bible ; and so long as it can maintain this position - we may be sure of its divine original ; for any mere human production, embracing so many authors, and reaching through so many thousands of years in its history, could not have avoided collision with scientific truth. Once more : theologians and philosophers should mutually require that those who undertake to pronounce judgment upon points of connection between science and religion should be well acquainted with both sides of the question. I do not say equally well acquainted ; for so limited are the human faculties that he who is eminent in one department of knowl edge can hardly be expected to be equally familiar with an other. But a respectable knowledge of any subject is essen tial to decide upon its relations to other subjects. And it ought to be a settled principle, that an opinion upon any point of science or religion is entitled to no respect if it can be shown that the man does not understand the subject upon which he writes. For eminence in one department of knowl edge gives a man no claims to credence in another which he 68 MUTUAL RELATIONS BETWEEN has never studied. A man, for instance, may be most dis tinguished in science, so that his word is law ; and yet, never having given his attention to theology, he is utterly unfit to judge of the bearings of scientific facts or theories upon re ligion. We listen with great respect to the opinions of an eminent divine upon those theological principles to which he has devoted so much thought and study. But if he undertakes to dogmatize upon matters of science, when his very language shows him quite ignorant of its principles, and swayed by prejudice, what claim can his opinions have to our reception or respect ? The distinguished Scotch divine, who uses the following lan guage respecting geology and geologists, no doubt supposed himself doing an important service to religion by his denunci ations. " Geology," says he, " as sometimes conducted, is a monument of human presumption, which would be truly ri diculous were it not offensive by its impiety." " Thus puny mortals, [geologists,] with a spark of intellect and a moment for observation, during which they take a hasty glance of a few superficial appearances, dream themselves authorized to give the lie to Him who made and fashioned them, and every thing which they see." The same may be said of another eminent divine, who applies similar remarks to the whole of physical science. " The third fact," says he, " here revealed, [in Genesis,] is, that this world was created in six days. Here, again, the Scriptures are at issue with science. Mod ern geologists tell us that this is not possible ; and all we need reply to the bold assertion is, with men this is impossible, but with God all things are possible.'1'' " Natural science is con fessedly progressive, and, therefore, comparatively crude. Geology is in its infancy." — Spring. Now, whatever effect such language may have upon persons THE PHILOSOPHER AND THEOLOGIAN. 69 who have given no attention to science, what but a bad influ ence can it have upon the naturalist, who sees, on the very pages from which I have quoted, the most decisive evidence that the writers do not understand the subject ? not from want of ability, but because other studies have engaged their at tention. Suppose that, in reading a commentary on Job, the writer had inadvertently disclosed the fact, that he knew noth ing of the Hebrew grammar, nor even of the Hebrew alpha bet. From that moment his criticisms, however much of talent they might discover, would be regarded with indiffer ence, if not with pity or contempt, by the Christian and the scholar. It would be easy to quote examples of an analogous char acter from the philosophers. I might refer to the extraordi nary and even ridiculous exegetical principles adopted by the phjjsico-theologists of the last century to prove their favorite dogma, that the principles of physical science are all to be found in the Bible, as given by Catcott in his work on the Deluge, and by Hutchinson in his twelve volumes entitled " Moses's Principia." But more appropriately may I refer to a writer of our own times, eminent enough in science to be selected to write one of the Bridgewater Treatises. In his interpretation of the phrase " windows of heaven," in Gene sis, Mr. Kirby makes it mean " cracks and volcanic vents in the earth, through which water and air rushed inwardly and outwardly with such violence as to tear the crust to pieces." I quote another example from a naturalist and philosopher still more eminent, not because it has the dreamy character of that just given, but because I know how the following pas sage has struck some of the most distinguished and liberal Hebrew and biblical scholars in our land. While they sat gladly at the feet of this author in all matters of physical 70 MUTUAL RELATIONS BETWEEN science, they regretted that the same discrimination and long study had not been given to the science of biblical interpreta tion before an exegesis of Genesis had been thrown out so confidently, which is contrary to the obvious sense and to the almost universal opinion of biblical writers. I speak not here of the truth or falsehood of the theory of this distinguished man, whose writings exhibit so much of the true spirit of re ligion, and who takes so noble a stand against the flippant scepticism of sciolists, but refer simply to this particular exe gesis of Genesis. " The advocates of identity of origin for all the several races of men, as springing from only one primitive pair," says Professor Agassiz, " have no argument to urge in sup port of that position, but simply a vulgar prejudice, based on some few obscure passages of the Bible, which may after all be capable of a different interpretation." " To suppose ,that all men originated from Adam and Eve, is to give to the Mo saic record a meaning that it was never intended to have." It is very probable that some may be ready to apply to me personally the exhortation, Physician, heal thyself. For some do regard me as having violated the rule which I am urging upon others, by advancing interpretations of Scripture which no sound biblical scholar can admit. On two points espe cially has this charge been made. I have advocated that ex egesis of Genesis which permits the intercalation of a long and indefinite period between the beginning and the first dem iurgic day ; and, also, that exegesis of Peter, which makes him teach that this earth and its atmosphere, after being burned up and renovated, will become the new heavens and the new earth. Now, were these interpretations original with myself, and now first proposed in opposition to the whole array of biblical THE PHILOSOPHER AND THEOLOGIAN. 71 critics, I might well confess myself guilty, and conclude that my zeal to sustain a favorite theory had blinded my judgment. But in fact, these views, both of Genesis and of Peter, have been advocated by the early fathers of the church, and by a large number of the ablest modern interpreters and divines. As to the meaning of Peter, Dr. Griffin says, that the view above referred to " has been the more common opinion of the Christian fathers, of the divines of the reformation, and of the critics and annotators who have since flourished." I must disclaim, therefore, both the honor and the odium of these views, and say, that if I am wrong in their advocacy, it is be cause I have been led astray by such men as Augustine, The- odoret, Justin Martyr, Origen, Luther, the elder Rogenmiiller, Tholuck, Dathe, Pye Smith, Patrick, Chalmers, Knapp, and Griffin. Finally, it ought to be a position admitted by the philoso pher and the theologian, that the facts and principles of sci ence, brought before an unsophisticated mind, are favorable to piety. A contrary impression prevails extensively ; just because not a few scientific men, in spite of science, and not through its influence, have been sceptics. Their hearts were wrong when they began the study ; and then, according to a general law of human nature, the purest truth became only a means of increasing their perversity. .But had their hearts been right at first, that same truth would have nourished and strengthened their faith and love. Why should it not be so ? For what is true science but an exhibition of God's plans and operations ? And will any one maintain that a survey of what God has planned and is executing should have an unfavora ble moral effect upon an unperverted and unprejudiced mind ? If it does, it must be through the influence of extraneous causes, such as pride, prejudice, bad education, or bad hab- 72 MUTUAL RELATIONS BETWEEN its, for which science is not accountable. O, no ! the temple of Nature is a holy place for a holy heart. Pure fire is al ways burning upon its altar, and its harmonies are ever hymn ing the praises of its great Architect, inviting all who enter to join the chorus. It needs a perverse and hardened heart to resist the good influences that emanate from its shrines. A consideration of the mutual interest of ihe theologian and ihe philosopher constitutes a second means for determin ing ihe principles by which their feelings and intercourse should be regulated. It hardly needs a formal argument to show, that it is for the interest of both to bring revelation and science into entire harmony. The established and intelligent Christian will not, indeed, be greatly disturbed because an alleged scientific dis covery is said to come into collision with the Bible. But there are others, predisposed to believe revelation, who will gladly seize upon such examples to fortify themselves in scepticism. Religion, therefore, suffers by merely apparent incongruity between science and revelation. Nor can it be a matter of indifference to philosophers, to be looked upon as throwing doubt upon man's highest hopes and interests, by those who defend these interests, and who have taken a most important part in time past in advancing science. Suspicion and alien ated feeling between Jhese classes operate most disastrously upon both ; and, therefore, mutual interest demands their unit ed efforts to remove apparent discrepancies. A second consideration of importance, in this connection, is, that science is the great storehouse of facts on which is based the whole system of natural religion. And when we recol lect that natural religion does not stop with the mere demon stration of the being and attributes of the Deity, but estab lishes his natural and moral government over the world, THE PHILOSOPHER AND THEOLOGIAN. 73 and man's correspondent obligations, — also his common, spe cial and miraculous providence, and the doctrine of his pur poses or decrees, — we see how important is this use of science. At this day, indeed, how can the theologian dispense with its facts in their religious applications ? Let the works of Ray, Derham, Wollaston, Paley, Crombie, Brown, Chalmers, and the other authors of the Bridgewater Treatises, testify to their importance. For though the divine may stand firm upon the evidence of history, prophecy, and internal character to sus tain the Bible, yet if he can show that its truths are in agree ment with nature, and are even sustained and illustrated by it, his appeal, in this thinking and reasoning age, will come home with much more convincing power. He cannot dis- • pense with the facts of science and yet be a workman that needeth not to be ashamed. On the other hand, the philosopher should not forget that the religious applications of science are its most important use. When he thinks what knowledge has done in elevating and civilizing society, and in multiplying the comforts and luxuries of life, he is apt to forget its religious bearings. But these, in fact, transcend in importance its worldly influences, as much as eternity transcends time. And most sadly does he degrade science who overlooks its religious applications. These form the ground of its truest dignity, and they alone link it to the permanently grand and the eternal. But philosophy may also be employed in defending and illustrating revealed truth. Of this we have a splendid exam ple in the " Analogy " of Bishop Butler, whose grand princi ple has been applied successfully by Barnes to nearly all the peculiar doctrines of revelation. Of all efforts to meet scep tical objections to evangelical Christianity, this is the most thorough and complete ; and were this work more carefully 7 74 MUTUAL RELATIONS BETWEEN studied, along with such authors as Chalmers, Harris, Whewell, Sedgwick, Isaac Taylor, and McCosh, who extend and illus trate analogous principles, the flippant and superficial sci olism of the day, that would metamorphose the Deity into natural law, would find little favor. Nor are these religious applications of philosophy confined to the older and more mathematical sciences. Nay, those more recent, and dependent mainly upon experiment and ob servation, when rightly understood, are remarkably prolific of religious illustrations. Chemistry and physiology, for exam ple, throw much light upon the doctrine of the resurrection of the body, and vindicate it against objections otherwise un answerable. The former science, also, points us to the true meaning of those scriptures that describe the destruction of the world by fire ; showing us that it is change of form in the matter of the globe, but not its annihilation. Meteorology teaches us how to understand the language of Scripture re specting the firmament above us. And geology, especially, lends confirmation to the biblical history, of man's creation as a comparatively recent event ; it shows us how we should understand the scriptural cosmogony, points out a new argu ment for the divine existence, and lends such decisive cor roboration to the revealed doctrines of special and miraculous providence, and divine benevolence, that these truths could not consistently be excluded from the creed of philosophy, though the testimony of the Bible were lost. Surely, then, the interests of theology demand that the reli gious applications of science should not be overlooked ; and, on the other hand, science should count it the highest honor to be able to throw even a ray of light upon God's written word. I venture here to suggest another use to which science may THE PHILOSOPHER AND THEOLOGIAN. 75 be applied by the theologian. It is well known that sharp discussions not unfrequently occur respecting the meaning of the language of the ablest divines after their decease ; and they are charged with teaching contradictory principles. It is well known, also, how great complaint is often made, by controversial writers, of the misunderstanding of their views by their opponents. But how seldom do discussions of this sort occur respecting the meaning of eminent mathematicians, natural philosophers, and naturalists ! Nor does this result from entire unity of views, and the certainty of every princi ple discussed in these sciences. But it springs mainly from the definiteness and precision of the language which is em ployed. Take botany or chemistry, for example : how can men be in doubt about the meaning of a sentence, when al most every word in it has a settled and usually a single sense ? I do not suppose that equal precision could be introduced into theology, because it treats of natures more subtile than those of physical science. But I suggest whether divines, in the definition of their terms, might not advantageously consult the directness, singleness, and precision of physical science more, and the wariness, subtilty, and equivocal senses of met aphysics less. I fancy that in the style of Dr. Chalmers, which, although sometimes too stately, is always clear, we have an example of this improved phraseology. I doubt whether posterity will hesitate much as to the meaning of his writings ; and perhaps the unsanctified ambition of the earlier periods of his ministry, which led him to devote so much time to mathematics, chemistry, and natural history, will be thus overruled to the benefit of theology. Every true philosopher, no less than the religious man, should be desirous that his pursuits may accomplish the most possible for the good of society ; fipr benevolence is a duty of 76 MUTUAL RELATIONS BETWEEN natural as we'll as revealed religion. Now, the cultivation of science alone, in a community where atheism or infidelity predominates, is most likely to prove a great curse. Knowl edge pufleth up ; and hence mere scientific acquisitions tend to foster pride, selfishness, and inordinate ambition, and -to exalt the brilliant iew at the expense of the degraded many. 4 The result will be, that the most furious passions of our nature will exhibit their deadliest malignity in a community where science is cultivated, but spurns the aid of religion. What a terrible illustration of this truth has been exhibited during the last century in the centre of European civilization ! Never did France show more of brilliant scientific skill than during the savage days of her first revolution ; and her whole subsequent history teaches us how dangerous it is to commit the power which science bestows into irreligious hands. The meteoric explosion which was the result, not only rent that unhappy country to atoms, but sent its iron fragments into every European land ; and the death groan that followed has hardly yet died upon our ears. It was a dear-bought yet im pressive lesson of the danger of committing scientific power into the hands of irreligion ; and it should lead the philos opher to feel the necessity of spiritual influence to control the energies of science. Truly, as Coleridge remarks, " all the products of the mere understanding partake of death ; " and as Lord Bacon still more appropriately observes, " in knowl edge, without love, there is ever something of malignity." But there is another important fact on this subject. The general diffusion of scientific knowledge through a community can never take place without the aid of Christianity. There may be an aristocracy of learning, as in the case just quoted, but religion alone will provide for general education. Left to the influence of any other principle, the favored and enlight- THE PHILOSOPHER AND THEOLOGIAN. 77 ened few will keep down and oppress the ignorant masses. Popular education is found only in connection with revelation. So says the history of the world ; and an analysis of human nature shows us that it must be so. Hence every philosopher who is a friend to his species will feel it his duty to promote the diffusion of Christianity as well as of science. Thus only can the greatest good be secured to the whole. The third means of ascertaining and settling the principles that should regulate the intercourse and feelings of the the ologian and philosopher is by an appeal to history and obser vation. We thus learn the results of many well-tried experiments on this subject; and these should have all the force of law, and be incorporated into the code of mutually obligatory principles. They are more certain than the a priori de ductions already considered, and I could wish that my space would allow a fuller enumeration of what has thus been taught One of the principles thus developed is the danger of exalt ing philosophy above revelation. Unhappily, we can hardly glance at a page of ecclesiastical history without finding in structive examples. Perhaps the Platonizing tendencies of the Christian fathers for many centuries are the most striking illustration in former times. It is hardly strange that those who came out of the schools of philosophy into the school of Christ should be gratified to find, and be ready to suppose they could find, a correspondence between the doctrines of their old and new masters. And how natural, in such a case, to accommodate the principles of the new leader to those of the old one ; or rather to exalt the teachings of the first above those of the last. Thus did the fathers ; and though Platonism was again and again driven out of the church, again and again 7* 78 MUTUAL RELATIONS BETWELN was it brought back — demanding from time to time a new exorcism. But though this incubus rested on the church for so many centuries, and often well nigh stopped its breath, modern divines seem to have gained little wisdom by the severe les son. Plato and Aristotle, indeed, no longer vex the church by name. But their spirit, like the exorcised demon of old, walking through dry places, and seeking rest in vain, has commissioned seven other spirits to return into the sacred enclosure, not merely to modify Christianity, but to expel it. Hence, in modern theological literature, we have profound works on the gospel, whose object is to prove the gospel a fable ; treatises on dogmatics, without any doctrines ; and lives of Christ, from which Christ is excluded. Instead of one or two leaders, as of old, we now have scores. Having the shoulders of those old giants, Plato and Aristotle, to stand upon and start from, it is only necessary to be provided with a huge pair of transcendental wings to seem very large to a wondering world, as they soar away into the mysterious ether, into which those old giants found it difficult to rise, because the clogs of common sense hung so heavily upon them. Justice requires me to add, in this connection, that the phi losophy which has thus been exalted above revelation so often and so disastrously is not that of induction, but of abstrac tion ; not that of Bacon, and Newton, and Whewell, but that of Hobbes, and Hume, and Diderot. I know that there always has been, and still is, a strong jealousy of physical science, as if it were hostile to religion ; but where is the evidence of such hostility? What philosopher of the Ba conian school has ever erected within the church a tower that overlooked and overawed Christianity itself, and made it a resort for those too proud to submit to revealed truth ? But THE PHILOSOPHER AND THEOLOGIAN. 79 how often has the deductive philosophy done this ! Divines seem prone to forget the distinction drawn with such a vig orous hand by Isaac Taylor. " The entire mass of intel lectual and theological philosophy," says he, " divides itself into two classes — the one irreconcilably opposed to the other. The first is, in its spirit and in all its doctrines, consentaneous with human feelings and interests. The second is, both as a whole and in its several parts, paradoxical. The first is the philosophy of modesty, of inquiry, of induction, and of belief. The second is the philosophy of abstraction, as opposed to induction ; and of impudence, as opposed to a respectful attention to nature and to evidence. The first takes natural and mathematical science by the hand ; observes the same methods, labors to promote the same ends, and the systems are never at variance. The second stands, ruffian-like, upon the road of knowledge, and denies progress to the human mind. The first shows an interminable and practicable, though difficult, ascent. The second leads to the brink of an abyss, into which reason and hope must together plunge. The first is grave, laborious, and productive. The second ends in a jest, of which man and the world and its Maker are the subject." A second instructive fact taught us by history and observa tion, is the strong tendency to substitute a dogmatic and denunciatory spirit for knowledge and argument. Men of superior intellect and extensive erudition are very apt to do this in respect to subjects to which they have never given special attention. Some new science or discovery has been brought forward in such an aspect as seems to the theolo gian to conflict with religion. He has never studied the sci ence, it may be, and cannot therefore hold an argument on the subject. But he feels deeply the wound inflicted on 80 MUTUAL RELATIONS BETWEEN revelation, and he cannot sit still and see that cause suffer which he loves so well. He denounces the new discovery, therefore, and gives no doubtful intimation that its advocates are sceptics, trusting to his reputation as a theologian to en force his opinion upon the public. Some, whose organ of veneration is large, swallow the ex-cathedra judgment with no wry faces. Others, more discerning, see through the ruse, and sigh over human weakness. Scientific men look upon the whole with silent contempt, nor deign to attempt an answer to dogmatism and personal abuse. Sometimes, however, a scene equally absurd is witnessed on the other side. A scientific man, desirous of extending his discoveries into the domain of religion, ventures upon inter pretations of Scripture, or statements of doctrine, that show him quite ignorant of both. The practised theologian points out the fallacy of his reasoning so clearly as to wound his pride. But, instead of generously confessing his error, he resorts to charges of bigotry, narrow-mindedness, and igno rance of science, and dogmatically maintains that science is to be followed, whatever becomes of revelation. He shows towards it and its defenders the same bitter, bigoted spirit which he censures in his opponents. Their arguments he cannot answer, because he has never studied hermeneutics or theology. And so he wraps himself up in the cloak of self- conceited wisdom, and substitutes contempt for logic. Men talk much of the odium theologicum, as if it were the quint essence of gall. But really, the odium scientiftcum is often a much more concentrated mixture. The most illiberal of all bigots are those who fancy themselves the very pinks of lib erality ; and pride never assumes such lofty airs as when it curls the lip of the self-satisfied philosopher who is destitute of Christian humility. THE PHILOSOPHER AND THEOLOGIAN. 81 The disastrous influence of mutual jealousy and hard speeches between theologians and philosophers is a third les son most impressively taught by history and observation. Although many distinguished divines have been eminent phi losophers, and science is largely indebted to the clerical pro fession, yet, in general, the two classes have kept very much apart from each other. This is particularly the case in re spect to the cultivators of physical science. In general they have an impression that theologians feel no sympathy with their pursuits, and are not only ignorant of science, but preju diced against it, as unfriendly to religion. And the fact that so few in the ministerial office do regard attention to natural science, by the ministry, as entirely appropriate, fosters this false notion. But it awakens deep prejudices in these scien tific minds against clergymen, because they cannot see why the ministers of God should not take interest enough in his material works to study them. Prejudice prevents that inti mate acquaintanceship which would be its cure. It engenders distrust, and produces severe judgments, and keeps those apart who should be cordial friends, because they are both engaged in the same great business of developing the works and ways of the Almighty. This jealousy and want of acquaintance with each other produces a reaction on the part of theologians, who, also, become censorious and distrustful of men of science. They learn that some such are sceptics, and they presume that nearly all are. Hence, when some new scientific discovery, is announced, which seems unfavorable in its bearings upon rev elation, theologians are at once suspicious that the author of it is intentionally aiming a blow at Christianity — although the greater probability is that its bearings upon religion never entered his mind. But too often, in such cases, the zealous 82 MUTUAL RELATIONS BETWEEN vindicator of the truth throws out such an insinuation in the public ear, and if the scientific man is not a meek Christian, the ungenerous suggestion may convert into an enemy of the faith one who before was only negligent of it, or indifferent towards it. But this is not the worst of it. Such a course produces a conviction on the public mind, that men of science teach one thing, and theologians another. Nor can there be a doubt that there is a strong disposition among intelligent men, who are not pious, to take sides with science, even when it seems hostile to revelation ; and thus may the severe and unfounded judgment of the theologian, in respect to science, confirm and multiply men of sceptical views. This point may be illustrated by the history of geology. Ever since Cowper, in his oft-quoted lines, charged geologists with digging and boring the strata in order to disprove the history of Moses, almost all subsequent writers have repeated the accusation ; and I doubt not that the almost universal be lief now is, that the works of geologists abound with open or covert attacks upon revelation. But the impression is entirely erroneous. In perhaps four out of five of those works, you will find able attempts to reconcile the facts of geology with Scripture ; but I have never met with a single attempt, in any language, by any respectable geologist, to adduce the facts of the science to the discredit of revelation. Many of them are, doubtless, sceptical ; but they have not done this thing, as they are charged. If it has been done at all, it is by men of no reputation as geologists. Yet probably it will require another quarter of a century to rid the public mind of this false im pression.* * How easy would it be to substantiate these statements by quotations from the most eminent geological writers of the last fifty years ; such as Jameson, THE PHILOSOPHER AND THEOLOGIAN. 83 Now all these false notions would be avoided, if men of science and theologians would cultivate a closer acquaintance. If men of science were often to come into contact with di vines, instead of finding them narrow-minded, bigoted, and unfriendly, as they now suppose, they would, in general, be gratified by their enlarged and liberal views, their ability and candor in looking at scientific truth, and their ardent love of all kinds of knowledge, and cordial efforts to promote it ; and many they would find to be successful and eminent cultivators of science. In like manner would scientific men appear in a quite different light to theologians. Instead of subtle and designing enemies of Christianity, they would find many to be its firm friends ; and nearly all entertaining for revelation the Silliman, Buckland, Coneybeare, Mantell, Sedgwick, Lyell, MacCulloch, Miller, &c. But I will refer only to a recent work by two eminent French geologists, C. D'Orbigny, and A. Gente, published in Paris in 1851, entitled " Geologie appliquie aux Arts et a 1' Agriculture." Coming from a city gen erally regarded as the centre of European scepticism, and whose learned men have been considered as unfriendly to the Bible, it is gratifying to find that these authors, after a laborious attempt to bring revelation and geol ogy into harmony, pass the following noble eulogium upon the sacred volume : — " In view of the chronological agreement between Genesis and the most authentic geological facts, we cannot but accord to this mysterious book Bomething profound and supernatural. If the mind is not convinced, it at least bows reverently before such writings, brought out in an age when we cannot suppose the first elements of the natural sciences were known, and which embraces a development of the principal events of which our globe has been the theatre. We find in Genesis something so simple, so touching, and so superior in respect to morality and philosophy, that the sceptic, as tonished moreover at the genius that could foretell facts which scientific re searches should demonstrate so many ages afterwards, is forced to acknowl edge that there is in this book the evidence of an inspiration secret and supernatural ; an inspiration which he cannot comprehend, which he cannot explain, but which strongly affects him, presses upon him, and controls him." -p. 107. 84 MUTUAL RELATIONS BETWEEN highest respect. Their chief fault is, that in their ardent and exclusive devotion to science, they are apt to neglect that higher attention to religion which its claims demand — a charge, however, which I fear lies equally against most other classes of society. They would find, in fact, almost without excep tion, that these men were ready publicly to express their re gard for religion ; and while they would contend for the full est liberty of investigation into every department of nature, they would resent the charge of intentionally aiming to injure the credit and authority of revelation. If I mistake not, a reference to the British Association for the Advancement of Science will not only confirm these sug gestions, but show that British divines "are ahead of Ameri cans on this subject. That association embraces all the most eminent scientific men in the kingdom, as well as many from the continent ; and they meet yearly to spend a week together in scientific discussions. Here we might expect, if any where among the cultivators of physical science, an exhibition of religious scepticism. But the fact is, a decidedly religious tone has always been exhibited in that meeting. Whenever a fitting opportunity presented, the addresses of the presiding officer, and of the members, have exhibited a spirit not only religious in the general sense of the term, but in its Christian sense. Said Sir R. H. Ingliss, the president, in 1847, " I will only add my firm belief, that every advance in our knowledge of the natural world will, if rightly directed by the spirit of true humility, and with a prayer for God's blessing, advance us in a knowledge of himself, and will prepare us to receive his revelation of his will with profound reverence." In echo ing similar sentiments from Dr. Abercrombie,- at the meeting in Edinburgh, in 1834, Professor Sedgwick remarked, that " the pursuits of science, instead of leading to infidelity, have THE PHILOSOPHER AND THEOLOGIAN. 85 a contrary tendency ; they tend rather to strengthen religious principle, and to confirm moral conduct." One of the most gratifying features of the meeting of this body in Edinburgh, in 1850, which I had the pleasure of at tending, was the strong religious influence which was mani fested. This resulted, in part, perhaps, from the fact that the meeting was presided over by that truly Christian philosopher, Sir David Brewster. But his noble address was warmly sec onded by others. Said Dr. Robinson, the eminent astrono mer, in complimenting Dr. Mantell's lecture on the gigantic extinct birds of New Zealand, " This lecture speaks to us of God ; yea, more, it speaks to us of Jesus Christ," — alluding to the fact that these birds were discovered by missionaries ; and that sentiment was warmly cheered by the immense audi ence, of more than one thousand persons, embracing some twenty of the nobility, a hundred members of the Royal So cieties of England and Scotland, sixty professors in the uni versities and colleges, a hundred physicians, and a hundred clergymen. Ay, a hundred clergymen ; and in the fact I dis cover the main secret of the religious tone that has charac terized these meetings. And here it is, as it seems to me, our British brethren are ahead of us in this country. For there is also an American Scientific Association, on essentially the same plan as the British. It has now been in existence twelve years, and I have attended all its annual meetings save two ; nor have I ever seen any other feeling manifested than re spect for religion. But I am sorry to say, that I have met there only a very few of my clerical brethren. If they de sire to witness in this body as decided an influence in favor of religion as is exhibited on the other side of the Atlantic, they have only to attend its meetings and take an active part in its labors. 8 86 MUTUAL RELATIONS BETWEEN A fourth lesson taught by history and observation is, that neither philosophy nor biblical interpretation have yet arrived at a perfect and unchangeable state. Mathematics is the only science that can lay claim to infal libility, and even this admits of progress ; so that new reli gious applications may arise from new researches. The other sciences range widely along the scale of probability and certainty in their conclusions. Many points in them all, and in some nearly every point, admit of further elucidation, such as may considerably modify their religious bearings. Let the history of philosophy, even in the exact sciences, and eminently in the psychological and moral, teach us how vain is the pretence that they can assume no new phase in relation to religion. How cautious, therefore, should the philosopher be, to distinguish between the settled and the changeable prin ciples of science, before he pronounces any of them in col lision with inspired truth ! On the other hand, however,. let the theologian remember, that, though the principles of the Bible be infallible and un changeable, not so is its interpretation. Passing by the wild rationalistic theory of accommodation in biblical hermeneutics, it is still true, that on many principles of their science exe- getical writers are not agreed. The result is diversity of sig nification, when they interpret the word of God. Yet to avoid misapprehension, let me avow my conviction, that, so far as the essentials of salvation are concerned, the Bible is so plain a book, that no theories of interpretation, advocated by honest Christian men, can conceal these great truths. In fact, so prominently do they stand out in the Scriptures, that it needs no rules to make them intelligible, save what com mon sense and common honesty supply ; and hence no soph istries of the interpreter can long conceal them from the THE PHILOSOPHER AND THEOLOGIAN. 87 people. But very different is the case with some of those parts of Scripture hard to be understood, and of others, which can not be understood till researches and discoveries in philology, history, and science have given us the clew. So long as these discoveries continue to be made will the meaning of some passages of Scripture be liable to modification ; and at pres ent these branches of learning are far enough from perfection. It is impossible, therefore, that the meaning of some portions of Scripture should not receive some modifications for a long time to come ; and he does the most injury to the cause of religion, who rejects every new interpretation, and considers it dangerous to disturb the settled notions of men as to the meaning even of the less important portions of Scripture. He must have a weak faith in the Bible who fears to have every passage in it subjected to the most thorough scrutiny, under the concentrated light which all literature and all sci ence can pour upon it. And he must have a very narrow view of literature and science who fancies that they have done all they can do to elucidate the sacred text. Yet how common the notion among divines, that, while " human science is a changing and a restless thing," theology — not merely its framework, but its entire covering, coloring, and appendages — has long since received its last finish ! The fifth lesson taught us by history and observation is the weakness and folly of predicting or apprehending injury to Christianity from scientific discoveries. Such fears and pre dictions are not uncommon. On the one hand, the infidel, by a hasty inference, feels confident that the new discoveries will give a deadly blow to what he regards a false system ; and he exults in the anticipated discomfiture of the Christian church. Some intelligent Christians, also, become alarmed at the threatening aspect of the new views, and tremble for 88 MUTUAL RELATIONS BETWEEN the result. But how vain are all such fears and predictions ! It is the fiftieth time in which Christianity has seemed to the sanguine sceptic and the timorous believer to be in great peril ; and yet not even an outpost has been lost in this guerilla war fare. Discoveries in astronomy, geology, chemistry, and physiology have often looked threatening for a while ; but how entirely have they melted away before brighter light and more careful study ! Moreover, every new assault upon Christianity seems to develop its inherent strength, and to weaken the power of its adversaries ; because, once discom fited, they can never rise again. It will be time for the infi del to begin to hope, when he shall see, what he has not yet seen, a single stone struck from one of the bastions of this massive fortress by his artillery. And strange that any be liever should be anxious for the future, when the history of the past shows him that every science, which for a time has been forced into the ranks of the enemy, and made to assume a hostile attitude, has, in the end, turned out to be an effi cient ally. History and observation sustain us in going further than this ; they show us that, as a general rule, the more threaten ing have been the developments of any science in its earlier periods in respect to Christianity, the more strong and abun dant have been its ultimate support and illustration of religion. The introduction of the Copernican system of astronomy seemed, to the divines of that day, utterly irreconcilable to revelation ; and they contended against it as if the life of re ligion were at stake. Nevertheless, the demonstrations of physics triumphed over councils and decrees ; but instead of proving the death of religion, what Christian does not rejoice in the rich illustrations and auxiliary support which revelation has derived from astronomy ? especially in furnishing to the THE PHILOSOPHER AND THEOLOGIAN. 89 commentator the true principle of interpreting texts of Scrip ture that relate to natural phenomena. So, too, chemistry was employed for a time by the exulting sceptic, and to the alarm of the timid believer, in disproving the future confla gration of the earth. Yet not only has this envenomed arrow fallen harmless to the ground, but the science has furnished materials enough for at least one volume as a prize essay, entitled " Chemistry as exemplifying the Wisdom and Benefi cence of God ; " and other similar volumes might easily fol low. During the early part of the present century, no science excited so much of this false alarm as geology. But already, if I do not mistake public opinion, the tables are well nigh turned, and, save here and there a disconsolate few, who have so long been chanting the death song of Christianity that they can never change their notes, the ministers of Christ now find among the religious applications of this science rich illustra tions of divine truths ; and from the disinterred relics of the deep-bedded strata there come forth a voice in defence of the peculiar doctrines of the reformation, and a new argument for the divine existence. So that, in fact, this new field of religious literature is already becoming attractive and pro lific in publications. To geology, therefore, may be applied the riddle of Samson: Out of the eater comes forth meat, and out of the strong comes forth sieeetness. Now, in view of such results, we may confidently predict that some recent and yet imperfect sciences, lying on the out skirts of physiology and psychology, although at present greatly perverted by sciolism, and made to bear unfavorably both upon morals and religion, will in the end afford a sup port to both, proportionably strong. What they need now is careful investigation by clear-headed men of the Baconian school, who are familiar both with physical and intellectual 8* 90 MUTUAL RELATIONS BETWEEN science. But so long have these subjects been in the hands of charlatans, or of men with limited and partial views, that able and respectable philosophers, especially among the cler gy, shrink from their investigation, lest the title of phrenolo gist, or mesmerist, or spiritualist should destroy their repu tation and usefulness. It ought not so to be ; and I am satis fied that not until this thorough investigation takes place will these branches of knowledge be placed upon the same sure footing on which other departments of experimental science rest. At present they seem to me like some large temple, or palace, mostly buried by rubbish, with only here and there some tower, or minaret, or column projecting above the sur face. Around these detached parts groups are gathered, en deavoring to show that each tower or column is a complete temple. But not till the vast piles of rubbish are removed will the real temple exhibit its true proportions and character. When this is done, I fancy that the structure will be found a noble one, and worthy of the infinite Architect. I have time to derive only one other lesson from history and observation on this subject. They show us how unwise it is to denounce any new discovery, or theory in science, when they are first broached, as hostile to religion ; and es pecially to take the ground that if the new views are true, the Bible must be false. There is a strong temptation to do this. Men of ardent temperament, who love the Bible, when any thing is advanced which can be construed into hostility to its statements, feel as we all do when any thing is suggested derogatory to the character of a near friend. We rush to the defence without waiting for the dictates of prudence ; and thus we may injure instead of assisting our friend. Much more liable are we to injure the Bible. There is no need of such haste. Christianity stands on too firm and broad a base THE PHILOSOPHER AND THEOLOGIAN. 91 to be overturned by one or a hundred such blows as have hitherto been aimed against it. The true policy is to wait for a time, to see whether we fully understand the new views, and whether they conflict with the letter or the spirit of revela tion. Suppose the theologian should take ground which he is compelled afterwards to abandon, and to fall in with the new discovery. With how bad a grace will he come over to the new ground after severely denouncing as infidels those who adopted it ! How likely to lose the public respect, and to make sceptics of those who were before only indifferent ! How mortifying must it have been to the theologians who, one hundred and fifty years ago, denounced astronomy, to see its discoveries at length introduced into the almanac, and testify ing of their bigotry to all classes ! Who can doubt that many a man, in despising them, was led to despise the sacred cause which they were appointed to defend ? Yet the theologians honestly believed that to admit the earth's annual and diurnal revolution would overthrow the Bible. But how much better to have waited a little before avowing their convictions ! How little heed, however, do men give to the mistakes of their predecessors ! The same eagerness and hot haste have been manifested in our own day to rush into the conflict with scientific men, as they have brought out new discoveries ap parently unfriendly in their bearing upon revelation. Divines, eager for the onset, have not waited till they could study the subject and understand it, but have rushed upon the foe, confi dent that by abstractions and denunciation, if by no other weap ons, they could crush him. Often have they found themselves in conflict with a windmill, and all they have accomplished has been to make themselves ridiculous, as with fallen crest and trailing plumes they have left the field. A little delay would have taught them that sometimes, at least, the better part of valor is discretion. 92 MUTUAL RELATIONS BETWEEN Allow me to refer to a very recent example, where the cau tion which I recommend would have been wisely adopted. Some of our zoologists have advanced views respecting the specific unity and unity of origin of the human race, that are in conflict with the common understanding of revelation ; and at once able divines took the ground that such views are irrec oncilably opposed to the whole scheme of the Bible. They may be so ; but why declare it before the subject has been more thoroughly discussed, and we are sure that we understand it ? It may turn out — and such is my own conviction — that the zoologists have too hastily decided this question, be cause they judged of it chiefly from facts in the limited field of their own science. Suppose it should appear that eminent naturalists are divided in opinion on the subject. Suppose that, when they assert that there are several species of men, they are unable to tell us what constitutes a species, and can not draw a line of distinction between species and varieties. Suppose that we should find zoologists entirely disagreed on the subject of hybridity. Suppose it should appear that the laws of distribution in the species and varieties of the lower animals, which is the grand argument for proving a diversity of origin in the case of man, should be found greatly modified in respect to him, by his cosmopolite character and ability, through superior mental endowments, to adapt himself to different circumstances. Suppose we should find examples of varieties of men, who have passed from the highest to the lowest races, save in color, through the influence of deterio rating causes long acting. Suppose it should appear that eth nology and psychology are entitled to as much weight in their testimony on this subject as zoology, and that they should pro nounce in favor of a unity of origin. Suppose it should be found that many other elements of this most difficult subject THE PHILOSOPHER AND THEOLOGIAN. 93 are yet not well enough understood to reason from, and de mand long and patient investigation. Or make the most un favorable supposition, viz., that the preponderance of evidence favors the idea of a diversity of origin. Is it quite certain that we must give up the Bible, or its more important doctrines ? Would the discrepancy appear so great as it did when the Copernican system was first announced ? Shame on us, that we feel so fearful in respect to God's Word, and those eternal truths that form the groundwork of the scheme of salvation ! Right is it that we should address ourselves manfully to every argument that bears upon revelation ; but how unwise, when it is wholly unnecessary, to take ground which we may be compelled with a bad grace to relinquish ! ., In conclusion, let me recapitulate the principles, which, as I have endeavored to show, should be the common creed, and regulate the intercourse and feelings of the theologian and philosopher. They should start with the principle that theology is entitled to higher respect, as a standard of appeal, than any branch of knowledge not strictly demonstrative. It should also be admitted that, as a means of moral refor mation and a regulator of human affairs, philosophy has little comparative power. They can agree, also, in the position, that entire harmony will be the final result of all researches in philosophy and re ligion. To the scientific man should be granted the freest and the fullest liberty of investigation. The language of science and of Scripture, as well as of popular religious literature, requires different, or at least modi fied, principles of interpretation. Revelation has not anticipated scientific discovery. 94 MUTUAL RELATIONS BETWEEN It is required that those who pronounce judgment on points of connection between science and revelation, should be well acquainted with both subjects. The facts and principles of science, to an unprejudiced, un sophisticated mind, are favorable to piety. They form a vast storehouse for the use of natural theology. They cast light upon and illustrate revelation. The harmony of science and revelation is mutually bene ficial. The cultivation of science, without the restraints of religion, often proves very disastrous. The general diffusion of science through a community is impossible without religion. The precise language of science may be useful in stating the principles of theology. History shows impressively the danger of exalting philoso phy above revelation. And the evils of substituting a denunciatory spirit for knowl edge and argument. It shows us also the evils of mutual jealousy and hard speeches between theologians and philosophers. And the folly and weakness of predicting injury to revela tion from scientific discoveries. The more threatening to religion the developments of any science at first, the more abundant will be its defence and illustration of religion ultimately. Finally, it is unwise hastily to denounce any new discovery as unfriendly to religion, and much safer to wait till its nature and bearing are well understood. Now, in conclusion, is not a code of this description needed ? I feel the imperfection of this first effort to draw it out ; but I offer it as the beginning of a necessary work. Had the THE PHILOSOPHER AND THEOLOGIAN. 95 common ground on which divines and philosophers may stand, been cleared up and marked out centuries ago, how many violations of sacred charity and good manners, how many un reasonable jealousies and prejudices, how many angry contro versies might have been prevented ; and how much nearer to entire harmony might science and religion ere this have been brought ! And how many more examples would the page of history have presented of genuine, humble-hearted, Christian philosophers, and of high-minded, liberal-hearted, philosophic divines ! It is such men that are wanted in the ranks of science and the ranks of theology ; and the principles which I have point ed out at this time are well adapted to form them. Could I excite a desire in the hearts of our students in theology to take this high position, I should not have written in vain. For what is a Christian philosopher ? He is a man who loves Nature, and with untiring industry endeavors to penetrate her mysteries. With a mind too large for narrow views, too generous and frank for distorting prejudice, and too pure to be the slave of appetite and passion, he calmly surveys the phe nomena of nature, to learn from thence the great plan of the universe as it lay originally in the divine mind. Nor does he stop when he has found out the mechanical, chemical, and organic laws of nature, but rises to those higher principles by which the moral relations of man to his Maker are disclosed. Hence he receives with gratitude and joy those richer dis closures of truth which revelation brings. To its authority he bows reverently and rejoicingly, and counts it the best use he can make of science to render it tributary to revela tion, and to the cultivation of his own piety. He exhibits a generous enthusiasm in the cultivation of science ; but he has a stronger desire to have it associated with religion ; and hence 96 MUTUAL RELATIONS BETWEEN he cherishes a high respect for those whose business it is to teach it. Indeed, the noblest example of a true Christian philosopher is seen in the able and faithful minister of the gospel, who employs a thorough knowledge of science, not merely to enlighten the ignorant, but to illustrate and enforce the higher principles of religion. On the other hand, if I were to give a definition of the highest style of a philosophic divine, it would be synonymous with that of the Christian philosopher. I should represent him as one whose grand object is to glorify God in the salva tion of men, by means of the gospel of Christ, but who made the whole circle of knowledge, literary and scientific, sub servient to his great object. Thus may the philosopher and the theologian be combined in the same individual. And why should they not ? To whom is it more fitting to be an interpreter of nature, than to him who interprets God's work of revelation ? Were such an identity more often realized, there would no longer be need to draw out a code of principles for regulating the conduct and feelings of those no longer twain. It would be like laying down a set of rules for regulating the conduct of the different members of the same individual towards one another. If, then, the theologian and philosopher may be thus identi fied, it must be because the principles of theology are in har mony with those of philosophy. Theology does, indeed, de velop principles which the sounding line of philosophy cannot reach. But so far as the two systems can he compared, they coincide. And we may be sure that whatever goes by the name of science, which contradicts a fair and enlightened exhibition of revealed truth, is -only false philosophy. To develop this harmony should be an object of the Christian ministry, second only in importance to its first aim — that of THE PHILOSOPHER AND THEOLOGIAN. 97 the personal salvation of men. Indeed, so enlightened at this day is the popular mind in matters of science, that a large class of intelligent men will not listen to the claims of Chris tianity till they are satisfied it does not conflict with science. It is gratifying to find our young brethren, as they issue yearly from our theological institutions, so well qualified, by their enlarged and accurate knowledge both of science and theology, to engage successfully in this noble work. We bid them God speed in it ; and so does the voice of history. For it tells them that the issue of every assault upon religion, with weap ons drawn from science, has been to bring revelation and phi losophy into closer agreement ; and hence may we confidently anticipate ultimate and entire harmony. It is gratifying, also, to remember, amid all the conflicts of opinion on earth, that all truth originally sprang from the same pure source — the infinite mind. But as it enters this world, its rays are sepa rated, colored, and distorted, by the media through which they pass ; by human ignorance, prejudice, pride, and passion. It is the noble work committed to divines and philosophers, so to prepare and adjust the rectifying glasses of reason and revela tion, that they shall collect and rearrange these scattered rays into a pure and uncolored beam, that shall spread the light of heaven over the darkness of earth. O, as I look down the vista of years, the sweet vision rises before me. The storm of conflicting opinions has passed by, and I hear only the distant, dying thunder, while the spent lightning plays harm lessly around the horizon. The sun of truth looks forth in glory behind the retiring cloud, on whose face it has painted a bow of harmonious colors — a sign of peace to the world, as its evening comes on, and a pledge of the cloudless and immortal day that is to succeed. 9 SPECIAL DIVINE INTERPOSITIONS IN NATURE.* ' No subject of theology has in it more true moral sublimity than the government of God over this world. Yet it is emi nently a practical subject. Our views of it afford a test of our piety and a type of its character. Nay, there is one feature of this government that has been regarded as the chief dis tinction between revealed and natural religion. We refer to Special Divine Interpositions. These have been supposed to be peculiar to revelation ; while nature moves on by uniform, unchanging and unchangeable laws ; nor does the whole his tory of those laws, as given by natural science, show a single example of interference or modification on the part of the Deity. We venture to call in question the correctness of these views. If we have read nature aright, it teaches a different lesson. That lesson may be worth learning. We choose for our subject, therefore, Special Divine Interpositions in Nature, as made known by science. Let us, in the first place, endeavor to affix a definite mean ing to the phrase Special Divine Interpositions. But here, perhaps, it may be necessary to interpose a re- * This address, essentially as here given, was delivered at the anniver saries of the Newton and Bangor Theological Seminaries. (98) special divine interpositions in nature. 99 mark, to prevent misunderstanding. We assume, as the basis of much of our reasoning, those views, now almost universal among geologists, and very common among theologians, which teach that this world existed through a vast and indefinite period before man was placed upon it. Such an opinion we think perfectly reconcilable with a fair interpretation of Scrip ture, though this is not the place to go into the proof. But let no one imagine, when we take such views for granted, that we mean to cast the slightest doubt upon the inspiration and literal truth of revelation. Let us be believed rather, when we express the conviction that, if admitted, they afford a strong corroboration and illustration of some most important doctrines of revelation. We proceed now to affix a definite meaning to the phrase Special Divine Interpositions. It requires but a few years' experience in this world to satisfy any observing mind, that natural operations are carried on in a settled order ; that the same causes, in the same cir cumstances, are invariably followed by the same effects. We call this uniformity of operation the course of nature ; and the invariable connection between antecedent and consequent we call the laws of nature. If we should see a new force coming in to disturb this settled order, we should call it a miracle. It might do this by a direct counteraction of nature's laws ; and this is the common idea of a miracle. But if an unwonted force were added to those laws, the result would be a miracle ; and so would a diminution or suspension of their action ; for in either case, the effect would be out of the ordi nary course of nature, and this we take to be the essential idea in a miracle. Perhaps the best and briefest definition of a miracle is, an event that cannot be explained by the laws of nature. » It may, and usually does, contravene those laws ; 100 SPECIAL DIVINE INTERPOSITIONS IN NATURE. but it may show only that their force has been increased or diminished. This, then, is one example of special divine interposition. Is there any other ? Most writers, theologians as well as others, would probably answer in the negative. For they admit only two classes of events in the universe — the mirac ulous and the ordinary ; the supernatural and the natural. / And yet most of them maintain that God exercises over the world a special providence. It is, indeed, true, that very wide differences exist as to the meaning of this phrase. One theo logian tells us that the providence of God " over the human family is termed special," and that " over those persons who are distinguished for virtue and piety is called most special." * Another calls that providence special " which relates to the church." t Another regards providence " special when it relates to moral beings, to men and human affairs." J But whatever may be the views of this phrase among technical theologians, the leading idea attached to it among Christians generally is, that God provides and arranges the circumstances in which men are placed, so as to meet the exigencies of individuals, just as he would have them met, and so as will be best for them. In other words, he provides means exactly adapted to meet the specific wants of indi viduals. Now, it is an interesting inquiry, whether this can be accom plished by the ordinary and unmodified operation of the laws of nature. We confess ourselves unable to conceive of but two modes in which it can be done. It is not difficult to imagine how God, at the beginning, when * Storr and Flatt's Biblical Theology, p. 240. t Buck's Theological Dictionary. t Knapp's Theology, Vol. I. p. 501. , SPECIAL DIVINE INTERPOSITIONS IN NATURE. 101 he established the laws of nature, did so arrange their opera tion as to bring about such results as the exigencies of every individual would demand, and at the exact moment desired. Human intellect is, indeed, confounded, when it attempts to conceive of a foresight so vast as to embrace in a glance the history of every individual of the race, and then so to arrange the countless agencies of nature, that every item in the his tory of the numberless millions of our race should be as care fully and exactly provided for as if only one individual were concerned. But we are certain that all this is perfectly easy to infinite intelligence. To suppose the contrary, is to de stroy the idea of omniscience ; and therefore we are bound to believe what we cannot comprehend. It will help us to conceive how God might thus arrange and adapt the laws of the universe to meet particular exigen cies, if we consider how it is that most events are brought about in our experience. We are apt to regard them as de pendent upon a single second cause, or, at most, upon a few causes, just because one or two are the immediate antece dents. But how few events are there that have not been essentially modified, at least as to the time and manner of their occurrence and in intensity, by what may be called lat eral influences ! We see a given cause operating, and we are apt to feel that we know what will be its ultimate effect But we forget that every event in the universe has a connec tion with all other events ; that, in fact, the whole series of causes in the universe constitutes a plexus, or network, in which if you remove one of the fibres, you remove the whole. Every occurrence is, indeed, dependent mainly upon a leading cause ; but the result may, after all, be prevented, or greatly modified, by any other cause. So that, as Bishop Butler remarks, " any one thing whatever may, for aught 9* 102 SPECIAL DIVINE INTERPOSITIONS IN NATURE. we know to the contrary, be a necessary condition to any other." * Conceive of a vast hollow sphere, in which balls of various sizes are moving in every direction, and with all degrees of velocity. Fixing your eye upon a single ball, you see it moving towards a given point, and, if it meet with no obstruc tion, you are sure that point will be reached. It may pass through its whole course untouched. But when your eyes are opened to discern the countless multitude of other balls flying through the same sphere, you feel almost sure that it will be deflected from its course, and its motion accelerated or retarded, by a multitude of collisions ; nor can you pre dict, by any mathematics which the human mind can master, what will be the exact course of that single ball. But how easy for God to do it ! and how easy for him so to place the other balls, and to give them such momentum, as will carry the single one to a given point at a given time 1 Now, this supposition gives us a not unapt representation of the manner in which the events of the world of matter and of mind are brought about. They are almost never the re sult of a single secondary cause, acting directly and simply, but of a great multitude of causes, modifying one another, and conspiring to bring out the final development. All these agencies were originally ordained and arranged by the Deity, in the manner that seemed best to infinite wisdom, which had infinite power at command. Can it be that they were put into operation without any plan, or with only a general object in view ? Who does not see that God might, at the begin ning, have given to these countless forces such degrees of strength, and such adjustment and direction, that they would * Analogy, Part I. Chap. VII. SPECIAL DIVINE INTERPOSITIONS IN NATURE. 103 bring about just such results in the history of every individual as would be desirable ? Thus would every case of special providence be met as certainly as if he should interfere mi raculously at the moment in each man's life when special interposition would be desirable. But with such a complex system of second causes in opera tion, it is easy to see how the same object could be accom plished by such a modification of some of those causes by the Deity, at any given moment, as would produce the desired result. And this might be done out of human view, so that man would see only the ordinary operation of nature's laws, and, therefore, there would be no miracle ; for any event that can be explained by the regular operation of nature's laws, as already remarked, is not a miracle. To most men these two modes of providing for special providences — the one by a disposition of the laws of nature in the divine mind from eternity, the other by some change effected at the moment by divine interference in the complex causes of events — we say, these two modes will seem to most persons very unlike. Indeed, they cannot see how there should be any thing special in an event that was provided for in the counsels of eternity, and which transpires as the result of arrangements then made. In order to make it special, they feel as if it were necessary that the Deity should inter pose, in some way or other, at the time of its ¦ occurrence, just as the mechanic finds it necessary to modify his machine, if he wishes to accomplish some specific object not provided for by its regular operation. Now, we feel confident that such impressions result from our limited views ; or rather, from the difficulty which finite creatures experience in understanding the mode in which an Infinite Being thinks and acts. It is hard to divest ourselves 104 SPECIAL DIVINE INTERPOSITIONS IN NATURE. of the idea that, in his processes of thought and action, God is altogether such a one as ourselves. But there are certain principles, true of the divine mind and divine action, that cannot enter at all into human powers and human conduct. One is, that no new plan or motive of action can ever enter the divine mind ; and, consequently, whatever plans we find developed in God's government must have been perfectly formed in -the counsels of eternity. Another principle is, that God never acts except under the guidance of those fixed principles which we call law. Hence miracles are brought about by fixed laws as much as common events ; that is, in the same circumstances we may expect the same miracle. The law of miracles does, indeed, differ from all others ; and this constitutes a miracle. But to suppose that God ever acts without the guidance of a settled principle is to impute to him a want of wisdom and character which we should be slow to charge upon an eminent man. No less absurd is it to suppose the Deity ever to act by the impulse of after thoughts, as men do ; or that he ever does any thing which he had not, eternal ages since, resolved to do in manner and time exactly as it takes place. If these are correct positions, what possible difference can it make whether we suppose God to have arranged the agen cies of nature at the beginning so as to meet every exigency, or to interpose whenever necessary to accomplish specific purposes by some new force or law ? Why is not the one as special as the other ? If he did in eternity arrange and balance the forces of nature in a particular manner, with the express design of meeting a particular exigency, what matter how many ages intervene between the arrangement and the event ? If a miracle was needed at a particular moment of human history, and God originally so arranged SPECIAL DIVINE INTERPOSITIONS IN NATURE. 105 the universe that the law of miracles should come in just at the right moment, would the event be any the less special than if we suppose he stood by at the moment, like a finite being, and by his power arrested or counteracted the laws of nature ? And the same is true of the means by which a spe cial providence is brought about. An eternal provision made for it shows merely the perfection of the divine plans and operations, but takes nothing from its speciality. A question may arise in some minds whether such views do not make all events special, though such a statement be a solecism. For if God has arranged the agencies of his nat ural and moral government so that all events happen just as he intended, on what ground is it proper to say that one of them is more special than another ? Do they not all meet some particular exigency ? And what more can any of them do ? The fallacy of such an objection lies in the assumption that * all events are equally the objects of God's intention. If it were proper to apply such a term to God, we might say that ,/ there is such a thing as an incidental providence — that is, an event which transpires as the necessary result of a certain arrangement, but which was not the specific object of such arrangement. Perhaps our meaning may be made obvious by reference to an illustration already employed. We refer to the supposition of a vast hollow sphere, with balls flying through it in all directions, and of course often interfering with one another. Take a particular ball, and admit that God has so adjusted its direction and velocity that, in spite of collisions, it shall reach a given spot at a stated time. Suppose that thus to reach the point is the grand object God has in view in setting the ball in motion. Yet, on its way to that point, it might encounter a multitude of other 106 SPECIAL DIVINE INTERPOSITIONS IN NATURE. balls ; and each collision would constitute events as distinct and as certainly foreseen and determined upon as the final one. But they might not accomplish any specific object, and be merely incidental to such a system of moving bodies. God might, indeed, in infinite wisdom, make them subservient to other objects besides the ultimate one ; but they might be mere incidental occurrences in such a system, which even Omnipotence could not prevent without altering the system. Now, have we not here two classes of events, equally the result of divine power and wisdom ? Yet one of them is special, and accomplishes a definite object ; the other is merely incidental, and may or may not be used for a spe- / cial purpose. Just so can we see how the special prov idence of God may be distinct from common providence, although both are equally the work of God. He has so ar ranged the agencies of his government, that certain specific objects shall be accomplished infallibly. But through the operation of those agencies a multitude of other events are brought about incidentally, which, although related to special providences, are not such in themselves. Another inquiry may arise in reference to some of the preceding reasoning. We have endeavored to show that spe cial providences may be the result of an original adjustment of the agencies of the natural and moral world, or of direct interposition by the Deity out of sight in modifying those agencies. Now, the question is, Which of these methods is actually employed in the divine government ? Can we deter mine which ? If by special interposition at the moment, is not the evidence of such interposition precluded by the very supposition we have made ? For the statement is, that the interposition must be made out of our sight; while within view, the event seems to be brought about by the ordinary SPECIAL DIVINE INTERPOSITIONS IN NATURE. 107 laws of nature, since, if made within sight, it would be mirae- ulous. All we can prove, therefore, is, that God can thus interpose and modify events within sight, by altering their antecedents out of sight ; and this is all that seems necessary for the purposes of religion. Hence it is that the Scriptures never raise any such questions as this, but simply and boldly assert the agency of God in the leading events in the history of nations, communities, and individuals. From the preceding course of reasoning we think we may consider the following positions as established : — First, that there are two modes in which divine interposi tion may take place — the one by miracles, and the other by special providences. By a miraculous providence we mean such a superintend- l ence over the world as interferes, when desirable, with the regular operations of nature within the sphere of human vis ion, and brings about events either in opposition to natural laws, or by giving them a greater or less power than in their normal state. By a special providence we mean an event brought about apparently by natural laws, yet in fact the result of some special agency on the part of the Deity, either by an original arrangement of natural laws, or the subsequent modification of second causes which lie beyond man's sphere of vision. Secondly, that both these modesof interposition take place in accordance with fixed laws or rules of action ; so that there is a law of miracles and of special providence, as well as of common phenomena. Thirdly, that the difference between miracles and special providence lies in this, that the former cannot, and the latter can, be explained by the laws of nature. Fourthly, that special providences may be the result of an 108 SPECIAL DIVINE INTERPOSITIONS IN NATURE. original arrangement of the laws of the natural and moral world such as to produce special results, or of a direct mod ification of those laws at any time by divine power in some of the links of causation out of sight. And, finally, that the events are equally special, whether the result of an original ordination in the divine mind, or of direct modification of natural agencies at the time of their occurrence ; nor can we, from the nature of the case, prove in which mode, or whether by both modes, divine wisdom acts. The main question now returns upon us — whether there is any evidence of special divine interposition in nature, save those which revelation has recorded. All such interpositions must, indeed, occur in natural operations, since it is their sus pension or modification that constitutes the interposition ; but the inquiry is, Does science, or common history, apart from revelation, contain any such records ? We waive the inquiry, at the present time, as to the evi dence which uninspired civil history may contain of special interposition, both because the field is too wide for the limits of this article, and has already been to a considerable extent explored. But the records of physical science have not hith erto, to our knowledge, yielded much of this kind of fruit. Our object, at this time, is to attempt to gather at least one cluster from that field. It must be confessed that, as a general fact, physical sci ence seems barren of any evidence of special divine inter ference — presenting us, instead, with operations as uniform and unchanging as mathematical laws can make them. Nev ertheless, if we do not greatly mistake, on some portions of the vast field we can discover the imprints of special and miraculous providence. SPECIAL DIVINE INTERPOSITIONS IN NATURE. 109 We shall speak first of special providence, but only in a brief manner. From the nature of the case it might be presumed that we should need a revelation to show that God had originally arranged, or directly modified, natural agencies so as to meet exigencies in the case of individuals or communities. For, as man sees it, such providence seems to be brought about by unmodified natural operations. It is hardly sufficient to prove special providence to find that great wisdom is shown in con triving and adjusting the laws and agencies of nature so as to meet the necessities of the animate creation. We want the proof that those laws and agencies have been so arranged and modified as to meet particular exigencies, and with those exigencies specially present in the divine mind. For all the purposes of religious faith, it is sufficient to show that God can do this ; and therefore we need not expect that nature will offer many examples which clearly show it to have been done. But believers in special providence suppose that they can find proof in their own experience, or that of others, that God has thus interposed either to bless or punish them. When they perceive that various causes have conspired — causes, it may be, both remote and undesirable — to bring about a certain result, they call it a special providence. We know that we need to be slow and cautious in drawing such inferences ; but not unfrequently the evidence is so clear and decided, that not to do it would be hurtful scepticism. We will mention one or two analogous cases in nature. It is no longer a conjecture, but a settled fact, that our globe has been the seat of several distinct economies of ani mal and vegetable life ; that whole races, if not over the whole globe at once, yet over wide districts, have become extinct, and been succeeded by new families ; and the new species 10 110 SPECIAL DIVINE INTERPOSITIONS IN NATURE. have been quite different from the old, requiring new condi tions as to location, climate, and food. Now, in every in stance yet known to us, the new races have been met by conditions exactly adapted to their wants. And this has taken place although the state of the globe has been one of slow but constant flux, both from the escape of its internal heat, the vertical movements of continents, and the action of vol canoes and water. When we consider how delicate a bal ancing of these and a multitude of other agencies would be requisite to accomplish such an object, how many causes must have been adjusted and made to converge to a given point through a long series of ages, it does seem to us that this case should be regarded as something beyond a mere wise and benevolent ordination of nature's laws, and as a special adaptation foreseen and provided for by the Deity, either by an original adjustment of natural laws, or by their subsequent modification, so as to bring the case fairly within the definition of a special providence. If any think that, by thus regarding a case of this kind, we should include all examples of wise adaptation as special providences, we can only say that there certainly is a difference that should be recognized between cases of this sort, which seem to have been the special object of divine wisdom and intention, and those incidental events which result from the adjustments necessary to bring about the special events. But the records of science furnish us with another class of examples in nature, still more indicative of a special prov idence. They are cases in which complicated causes have operated through vast periods of duration anterior to man's existence, or even anterior to that of scarcely any of the more perfect animals, in order to provide for the wants and happiness of those animals, especially of man. Laws, appar- SPECIAL DIVINE INTERPOSITIONS IN NATURE. Ill ently conflicting and irregular in their action, have been so controlled, and directed, and made to conspire, as to provide for the wants of civilized life untold ages before man's exist ence. In those early times, vast forests, for instance, might have been seen growing along the shores of estuaries ; and these, dying, were buried deep in the mud, there to accumu late thick beds of vegetable matter over large areas ; and this, by a long series of changes, was at length converted into coal. This could be of no use whatever till man's existence, nor even then, till civilization had taught him how to employ this substance for his comfort, and for a great variety of useful arts. Look, for instance, at the small island of Great Britain. At this day 15,000 steam engines are driven by means of coal, with a power equal to that of 2,000,000 of men ; and thus is put into operation machinery equalling the unaided power of 300,000,000 or 400,000,000 of men. The influence thence emanating reaches the remotest portions of the globe, and tends mightily to the civilization and happiness of the race. And is all this an accidental effect of nature's laws ? Is it not rather a striking example of special prospec tive providence ? What else but divine power, intent upon a specific purpose, could have so directed the countless agen cies employed through so many ages as to bring about such marvellous results ? Or take an example on a still more gigantic scale. It is already ascertained that, by the same process of vegetable growth and decay in the hoary past, thick beds of coal have been accumulated in the rocks of the United States over an area of more than 200,000 square miles, and probably many more remain to be discovered. Yet, upon a moderate calcu lation, those already known contain more than 1100 cubic miles of coal ; one mile of which, at the rate it is now used, 112 SPECIAL DIVINE INTERPOSITIONS IN NATURE. would furnish the country with coal for a thousand years ; so that a million of years will not exhaust our supply. What an incalculable increase of the use of steam, and a consequent increase of population and general prosperity, does such a treasure of fuel open before this country ! If our numbers should become only as many to the square mile as in Great Britain, or 223, there is room enough this side of the Rocky Mountains for 500,000,000 ; and including the western slope of those mountains, for 700,000,000 ; equal almost to the present population of the globe. And yet all that has been thus far seen in this country, and all that is in prospect, is only an ac cidental, or incidental, event in his theology who admits no special providence in nature. We are not of that number, for we not only believe that God, through vast cycles of duration, directed and controlled the agencies of nature, so as to bury in the bosom of this continent the means of future civilization and prosperity, but that a strong obligation hence results for every one living here to throw all his energies into the work of making this land a glory and a blessing to the nations. Let us go once more on the wings of imagination back to that remote period of our world's history, when most of its present continents were beneath the ocean. As we hover over the waters, we see them agitated by internal forces, and now and then smoke and ashes, and it may be flames, issue from their surface. Submarine volcanoes are pouring forth their contents ; and could we look beneath the troubled waves we should probably see beds of various kinds thrown out by the volcano, spreading themselves along the bottom. Among these beds we should probably see gypsum and common salt. But what has this to do with special providence ? Let the ages roll on and we shall see. By and by that ocean's bed is slowly lifted above the waves. Those waves, during its SPECIAL DIVINE INTERPOSITIONS IN NATURE. 113 emergence, cover it with a soil adapted to vegetation. Man at length fixes his dwelling upon it. He discovers, among the exposed strata, the gypsum and salt which he so greatly needs, and which by ingenuity and industry he can extract. And thereby can he greatly multiply his comforts and his numbers. In like manner might we go back and trace out the origin of the various ores, the marbles, the granites, the porphyries, and other mineral treasures so important to an advanced state of the arts, and of civilization and happiness. And we should find them originating in agencies equally remote, equally cha otic and irregular, and seemingly as much removed from all connection with man's long subsequent appearance. But it does seem to us that, during the long series of preparatory agencies, we can every where see the finger of God's special providence pointing to the final result. But we turn now to inquire, in the second place, what evi dence we have, in the records of science, of God's miracu lous providence ? And we take the position that, in the nat ural history of our globe, we meet with phenomena explicable only by miraculous intervention. Not to speak of the earliest condition of the world, which hypothesis alone can describe, let us follow back its history only to the time when legitimate theory shows it to have been in a molten state. That its internal parts are still in that con dition, and that its now solid crust was once so, seem to us to be proved by fair inference from facts ; and such is the opin ion of almost all scientific men. Think of it now in that condition — a shoreless ocean of fire. It is not difficult to conceive how, by the radiation of its heat, a solid crust should form, and at length the water condense upon its surface, while volcanic force should form such inequalities as would make 10* 114 SPECIAL DIVINE INTERPOSITIONS IN NATURE. beds for the oceans, and elevations for continents. Nay, by the action of the waves and the atmosphere, soils might be accumulated upon the surface. But, in spite of all that merely natural operations could do, what a scene of utter des olation and loneliness would it present ! That wonderful power which we call life, and the still more mysterious prin ciple of mind, would be absent. How, then, were the num berless forms of organism, animal and vegetable, possessed of life and instinct, and some of them with powers of intellect, — how were these introduced ? If miraculous interposition be not necessary here, we know of no exigency in which it can be ; and we may as well dismiss the idea from our phi losophy and our theology. Just see what the problem is : nothing less than to take a world of rock, more or less com minuted by water, and to convert it into essentially such a world as the present ; to take a world utterly dead and deso late, and spread through its atmosphere, its waters, and its solid surface, ten thousand forms of life and beauty. Has nature any hidden inherent power to do all this ? Why, then, can we not lay our finger upon a single manifestation of cre ative power in nature in these latter times ? O, that power is the prerogative of the Deity alone. AVho shall have the bold ness, and even the impiety, to transfer to blind, unintelligent law, what demands infinite intelligence and infinite power, miraculously exerted ? And yet there have always been men who have done this ; not, indeed, in the bold language in which we have stated the principle. Yet some of them have confessed that their object was to sustain atheism. Others have said merely that they meant to show that every thing, even the creation of animals and plants, was accomplished through the inherent self-creat ing power of law ; but they left the origin of the laws to each SPECIAL DIVINE INTERPOSITIONS IN NATURE. 115 one's own convictions. Nay, some have attempted to recon cile this creation by law, not merely with theism, but with a belief in revelation. This is the form in which this hypothe sis ha^ clothed itself in our own day. In such a dress it has ventured forth from the philosopher's study, where it has so long been isolated, and become incorporated with the fashion able literature of the day. And it has enough of plausibility about it to make it popular with men who have only a gen eral, but not a minute acquaintance with science, and who, afraid to live without some religious system, are yet unwilling to adopt one that brings God near. This is not the place to discuss such views. We will only say, that true philosophy must reject this hypothesis ; first, because the facts adduced to sustain it, when scrutinized, are too few ; and secondly, because for every fact seemingly in its favor, a thousand tes tify against it. Accordingly, all the great living and recently deceased masters of physical science reject it. Does it ap peal to anatomy and physiology ? Cuvier, Owen, and Car penter cry out against it. Does it evoke the aid of chemistry ? Berzelius, Turner and Liebig see its shallowness. Does it call on zoology for aid ? Agassiz and Ehrenberg can refute its claims. Does it search the archives of geology for sup port ? Sedgwick, Miller, Lyell, and D'Orbigny can show how certainly they will fail there. Or, finally, does it appeal to botany ? Hooker and Lindley, Torrey, and Gray, know that it will certainly glean nothing to sustain it on that flowery field. The fact is, it is only here and there that a second- rate naturalist will sympathize at all with such dreamy views. But there is another, and perhaps a more plausible mode of evading the general argument for the miraculous introduc tion of organic life upon our globe. When we descend into the rocks a certain distance, say six or eight miles, we reach 116 SPECIAL DIVINE INTERPOSITIONS IN NATURE. those that contain no remains of animals or plants, and show the metamorphic action of heat, by which they have been partially or wholly melted. Now, most geologists consider this horizon as the starting place of life on our globe, and that the rocks below it were formed before the existence of animals or plants. But some — and they eminent geologists — main tain that these lower rocks did once contain organic remains, which have been obliterated by the influence of the intense heat, and that, therefore, we cannot tell when life first ap peared on the globe. For aught we know, these metamor- phisms may have been going on forever. A few years ago it might have been difficult to prove di rectly that this hypothesis is false, though the history of the rocks afforded many presumptions against it. But the re searches of the last few years among the oldest of the fossi- liferous rocks have furnished its full refutation. For it has been ascertained, that both in Great Britain and in this coun try, stratified rocks, several miles in thickness, exist below those containing fossils, and yet retain so much of a mechan ical character, and are so partially metamorphosed, that if ever animals and plants existed in them, they would not have been obliterated. The metamorphic action has not been suf ficient to melt down the pebbles and fragments originally de posited, and therefore not great enough to destroy the harder parts of organic beings, had they been present. Here, then, we have an indisputable horizon of life, below which there is no reason to suppose it ever to have existed. But even if we admit that the apparent is not the real ho rizon of life in the rocks, there is another scientific fact that proves it did once begin, however far back we may suppose the metamorphic cycles to have extended. In other words, we can prove that there was a time when life did not exist on SPECIAL DIVINE INTERPOSITIONS IN NATURE. 117 this globe, and consequently a time when it was first intro duced. And this is the argument : — If any body, such as the earth, having a certain tempera ture, be surrounded by a medium, or by other bodies, with a lower temperature, it is certain, from the laws of heat, that the warmer body will continue to give off its heat to the colder ones, till at length they will be brought to the same tempera ture, unless the higher temperature of the central body is maintained by the perpetual generation of heat within itself. Now, we know that at present the earth is placed in exactly this condition ; for it can be proved that the temperature of the space surrounding it is at least fifty-eight degrees below zero. Consequently heat must be continually given off into the planetary spaces ; and unless there be some internal source of heat, the earth must he growing colder. When did this cooling process commence ? Those who believe an indefinite series of organic beings to have existed on the globe, will not surely fix a beginning, because that would be yielding the main point in their hypothesis. Yet it is certain that, if the earth has been cooling for an indefinite period, the time must have been when its surface was too hot for animals and plants to live upon it ; nay, when it was in a melted state. There must have been a time, therefore, when the first animals and plants were commanded into existence by the miraculous fiat of Jehovah. For the idea that the earth possesses within itself a power for the indefinite renewal of its heat as it es capes, finds no support in philosophy. We can conceive how heat might be produced while combustible substances were burning, but we know of no possible way by which an indefi nite supply could be evolved. We are unable to conceive how any philosophic mind can escape the force of such reasoning as this, which natural the- 118 SPECIAL DIVINE INTERPOSITIONS IN NATURE. ology brings forward to prove a period in the history of this world when it was destitute of organic races. But this is not the only argument which science can offer to prove mi- raculous*interposition in nature. A second proof, quite inde pendent of the first, is found in the fact that the earth has been the seat of several nearly independent systems of life, since animals and plants were first introduced. A certain group, wisely adapted to one another, and to the state of the air, the waters, and the surface, as well as to the food and the temperature, have flourished for a long period ; and, as some of these circumstances have changed, they have either grad ually died out, or have been simultaneously destroyed by some catastrophe ; so that few if any species have survived. Af terwards new races have been introduced, exactly fitted to the altered condition of things. These also, after flourishing long, have disappeared, and another and another system has suc ceeded, until we can distinctly trace five economies previous to the existing races. Many writers say that the number of systems has been much greater ; and, were we to limit our views to portions of the earth, it is undoubtedly true. But we can show that all the races, animal and vegetable, have been changed at least five times, over the whole globe ; and five such changes are as good for the argument as five hun dred. For though we can see how, by natural operations, organic beings can be destroyed, yet what but infinite wisdom and power can re people the lifeless waste ? This question we have considered under our first argument, and hope we have shown that nothing but miraculous power could have done it. But there are some peculiarities that attended the introduc tion of successive races, which deserve notice. From the nature of the case, the world must have been preparing, by SPECIAL DIVINE- INTERPOSITIONS IN NATURE. 119 the reduction of its temperature and increased productiveness of its soil, for a greater variety of organic beings, and for those of more delicate and perfect organization. And we find that, at the successive epochs of creation, there was a corre spondent increase of the higher races, " a gradual ascent to wards a higher type of being," * in connection with " a grad ual improvement in the style and character of the dwelling place of organized beings." f This is called the doctrine of progression ; and it obviously points to a beginning, not only of organic races, but of the present system of inorganic na ture, and requires miraculous divine interposition. It is well known, however, that at least one distinguished geologist takes opposite views of this subject, and maintains " that the existing causes of change in the animate and inan imate world may be similar, not only in kind, but in degree, to those which have prevailed during many successive modi fications of the earth's crust." This is called the doctrine of uniformity, or non-progression. It is not intended by its able advocate to teach the world's eternity, although it has that aspect ; nor does it conflict with the idea of miraculous inter vention in the creation of animals and plants ; for it admits that " the succession of living beings has been continued, not by the transmutation of species, but by the introduction into the earth, from time to time, of new plants and animals ; and that each assemblage of new species must have been admi rably fitted for the new states of the globe as they arose, or they would not have increased, and multiplied, and endured for indefinite periods. J Even the doctrine of non-progression, then, is consistent with miraculous interpositions in nature. Much more does * Sedgwick. t Hugh Miller. J Lyell's Manual of Elementary Geology, p. 501. 120 SPECIAL DIVINE INTERPOSITIONS IN NATURE. the doctrine of progression demand it. And we confess our selves campelled to subscribe to the latter doctrine. So far as inorganic nature is concerned, we have already assigned a. reason for this opinion. Perhaps the evidence from organic nature is not as strong, because we cannot say certainly how many of the more perfect animals will yet be discovered in the older rocks. But so far as we do know, the progression has been very decided. More than 24,000 species of animals have been dug out of the rocks, 700 of which are mamma lia or quadrupeds. But 695 of these occur within 2000 or 3000 feet of the surface, while in all the 54,000 feet below, only five species have been found. Birds, the next less per fect class of animals, are scarcely more abundant in these lower rocks. Reptiles are more numerous, and extend to a greater depth, while the fishes, the least perfect of all, are still more abundant, and are found nearly at the bottom of the series. And the same increase of numbers would be found were we to descend still lower on the scale of animals. All this accords with the doctrine of progression, and so do the facts respecting plants. Now, making the largest allowance for future discoveries, it seems hardly possible that it will ever appear, that as large a proportion of the higher orders of ani mals and plants existed in the earlier periods of our globe as at present. But we hasten to offer one more proof of God's miracu- ¦J lous interposition furnished by the records of science. It is the creation of man. All observation teaches us that he was one of the last of the animals that was placed upon the earth. In vain do' we search through the six miles of solid rocks that lie piled upon one another, commencing with the lowest, for any trace of man. And it is not till we come into the upper most formation, — we mean the alluvial, — nay, not till we get SPECIAL DIVINE INTERPOSITIONS IN NATURE. 121 almost to the top of that, merely in the loose soil that is spread over the surfade, that we find his bones. And yet these, formed of the same materials as the bones of other animals, would have been as certainly preserved as theirs in the lower rocks had he existed there. The conclusion is irre sistible, and it is acquiesced in by all experienced geologists, that man did not exist as a contemporary of the animals found in the rocks. At least five vast periods of time, with their numerous yet distinct groups of organic beings, passed over this globe before the appearance of man. This is not a dreamy, hypothetical conclusion, but a simple matter of fact, which has been scrutinized with great care, and by some un friendly to revelation, who would gladly have found it other wise. But no fossil man or works of man have been discov ered below alluvium, (in which we include drift;) nor would any really scientific man risk his reputation by maintaining the existence of the human species earlier than the alluvial period. What an astonishing exhibition does this scientific fact bring before us ! Suppose we could explain by chemical and or ganic laws how the inferior animals were gradually developed from one another in the successive periods of our world's his tory. Yet here we have the phenomenon of a being intro duced at once, superior somewhat in organic structure to the other animals, but raised immeasurably above them all by his lofty intellectual and moral powers — a being destined to take the supreme control of all inferior natures, and, so far as need be, to subject them all to his will ; and, in fact, to convert the elements into servants to do his pleasure. The anatomist can, indeed, describe his organization ; the physiologist can point out the functions of his organs ; and the zoologist can assign him his rank at the head of animate creation ; but how is the 11 122 SPECIAL DIVINE INTERPOSITIONS IN NATURE. psychologist baffled when he attempts to unravel the wonders of his spiritual powers ! and the theologian, when he looks into the depths of his moral and immortal nature ! And did it demand no miracle to bring such a being upon the stage, and fit him exactly to his condition ? What greater miracle does even revelation disclose ? Admit, if you choose, that all other events on the globe — even the creation of all other organic beings — might have been accomplished by ordinary laws ; yet, so long as the great fact of man's creation stands out so conspicuously on our world's history, we need nothing more to establish, beyond cavil, the reality of divine interpo sition in nature. God has impressed his own signet so deeply upon this last act of creation, that scepticism dare not directly attempt to deface it. And this grandest miracle of nature is also the greatest of revelation. It stands up a lofty and im movable rock, amid the ocean of existence, to arrest and beat back the waves of unbelief, and to reflect the glories of divine power and wisdom. We might add other arguments corroborative of the same principle. But if the three which we have adduced, inde pendent and cumulative as they are, do not satisfy, we despair of producing conviction. We may be laboring under some hallucination on this subject ; but we cannot see why the evi dence of special divine interpositions in nature is not as clear and decided as in revelation. The only difference seems to be, that in the one case we depend on the testimony of living witnesses ; in the other, upon the conclusions of science. But if such interpositions have been made in nature, it is easy to see how important are the bearings of the fact both upon the ology and upon piety. See, for example, how the miracles of nature take away all presumption against the miracles of revelation. We all know SPECIAL DIVINE INTERPOSITIONS IN NATURE. 123 that this has been a favorite point of attack both in ancient and especially in modern times. The grand argument has been, that miracles, being contrary to all experience and all analogy, cannot be proved by human testimony. We remem ber the metaphysical network woven by Hume on this sub ject, which he fancied too strong for any Christian champion to break through ; and we know, too, how many professed Christians at this day assume in their theology that miracles are only ingenious myths. Little did these men imagine what a record on this subject lay concealed within the stony leaves of the earth's crust, or that the hammer of the miner and the geologist would bring facts to light that would sweep away at once all their ingenious quibbles. So long as Christians could meet them only with abstract reasoning they felt strong. But now we lay open the solid rocks, and show them there miracles of creation as wonderful as the miracles of revela tion, and of them, the creation of man, perhaps the most remarkable of all, is the same in both records. We show them that interference with- nature's usual course has been a rule of God's government from the remotest times ; and the conclusion is. irresistible, that what God has done during the earlier economies of our world he will be likely to repeat during the human era, should his purposes require it. Not less effectually does this subject remove all improb ability from the doctrine of special providence in the case of individuals and communities. Nay, the facts which we have presented form an a fortiori argument for the exercise of such a providence. For if we find proof registered on the rocks, that God has taken care to adapt the state of the world wisely and benevolently to the nature and wants of the lower animals that have peopled its changing surface, and prospec tively and specially for the comfort and happiness of man as 124 SPECIAL DIVINE INTERPOSITIONS IN NATURE. a race, we may with still stronger confidence presume that he will see to it that the exigencies of individuals of that superior race will be taken care of. Henceforth, then, when we wit ness the exhumation, from the quarries, of the strange beings that once occupied the earth, let us not regard them as mere objects of an idle curiosity, but as so many arguments to show us that God will take care of our individual interests ; and when we wander through the deep-seated coal mine, or any other excavation where human industry is extracting mineral treasures to advance civilization and happiness, let our faith gather thence an argument for implicit trust in that prov idence which, in the depths of past ages, buried up these de posits for the special use of civilized man. How delightful for the Christian thus to find food to nourish his faith, where most men see only rugged rocks, and think only of accumu lating wealth ! So, too, this subject takes away all presumption against the doctrine of special divine influence on the human mind ; for if God would work miracles to accomplish his purposes in the natural world, much more ought we to expect that he would exert those influences upon the human mind which are not inconsistent with free agency, and are essential to prepare it for a higher state of existence. This he can do without a miracle ; and it is an exigency which the whole history of his providence leads us to expect will be met in this manner. See, too, what a new and interesting argument may be de rived from this subject for the divine existence. The usual argument, that from design, requires us to prove, or assume, a beginning to the matter of the universe ; and here the athe ist, hiding himself in the fogs of the doctrine of chance, and an eternal series of things, can make a quite formidable show of argument. But admitting miracles in the modifications of SPECIAL DIVINE INTERPOSITIONS IN NATURE. 125 matter, we need not carry our thoughts back beyond those modifications, and may leave the question of the origin of matter untouched, without any injury to theism. We thus get rid of a multitude of dreamy abstractions which have so long enveloped the argument for the divine existence with a mist. We force the atheist out of the obscurities of the de ductive, into the clear light of the inductive, philosophy. We bring the subject down from the airy region of metaphysics, and place it on the firm ground of common sense. This subject, also, may be made to subserve another pur pose, no less important. It aims a deadly blow at all those subtle systems of religion founded on the supposed unending uniformity of nature's laws, and their inherent power to ac complish all the changes of the organic and inorganic worlds. Some of these systems, as we have remarked in another con nection, admit that there might be a Deity to ordain these laws originally ; but that is a question of no great importance, since it is the laws themselves, and not divine intervention, that have taken the world in the state of nebulous vapor, con densed it into a sphere, brought in at first a few species of animals and plants of the simplest organization, in the state of monads, and from them gradually developed all the higher forms of life by the force of external circumstances and an internal tendency to improvement, until, at length, as the last act of the drama, man, in the form of the negro race, was evolved from the semi-quadrupedal orang, and, still pressing onward, has assumed the loftier character of the Caucasian. Now, either the entire history of our globe, which has been dug out of its stony archives, is false, or this hypothesis is untrue. The history is based on facts, gathered from a thou sand fields, widely scattered, yet all teaching the same lesson ; the hypothesis is speculation merely, springing from a few 11* 126 SPECIAL DIVINE INTERPOSITIONS IN NATURE. supposed facts, half buried in fog and twilight. Which shall we adopt ? Philosophy cries out, responsive to the voice of nature, It is God, and not mere law; an infinitely wise and powerful God, the God who doeth wonders, whose miraculous interpositions are recorded in the volume of nature, as well as in the volume of revelation. Finally, this subject identifies the God of nature with the God of revelation. We greatly mistake the general senti ments of" mankind, if they do not feel that the Deity recog nized by science, is a quite different being from the Jehovah of the Scriptures. The first is regarded, indeed, as infinitely perfect, but as distant and uninterested in human affairs, binding the iron chain of law around all created things. But the God of revelation is an infinite Father, who is ever near his children, watching their every step, with an ear ever open and quick to hear their cry for help, and with a heart of boundless love to sympathize with them in all their trials. It is these different aspects in which the Deity is presented, that makes the religious man jealous of those views of theology which science offers ; and it is because he does not wish to feel that God is so near, and so observant of his actions and thoughts, that often the scientific man is disgusted with the God of revelation. But this subject shows us the same God in both dispensations. He who so often interposed mirac ulously for his ancient chosen people, and providentially, at least, for the followers of Christ in every age, — that same God, as modern science informs us, has shown the same watchful care over the material creation in all ages, and specially interposed, whenever necessary, for the welfare and happiness of all sentient beings. And herein does the pious heart recognize in the God whose glory is seen in the heavens, and who has filled this lower world with beauty, the same SPECIAL DIVINE INTERPOSITIONS IN NATURE. 127 infinite Father, whose wisdom and mercy shine so gloriously in the plan of redemption. If these views becorrect, do they not give to the works of creation a double charm to the Christian heart ? And do they not suggest the inquiry, whether those who preach the gospel might not make much more use than they do of natural reli gion ? If we mistake not, there is a prevalent jealo'usy of facts and principles derived from nature ; just because those facts have been sometimes perverted to throw discredit upon revelation. But we have long been satisfied that, from the fields of natural science, efficient support may be derived to some of the peculiar, and to the carnal mind the most offen sive, doctrines of revelation. We have brought forward, in this article, only a single cluster of the fruit from that field. But other and richer clusters, we doubt not, would reward the search of abler minds. See what such men as Chalmers and Harris have done ; and let all, who now preach or who mean to preach the gospel, follow in their steps, and we doubt not that Christians, instead of being fearful that science and rev elation are in conflict, would find that they sustain and illus trate each other, and that the heart of piety might be warmed at the shrine of nature, as well as at the cross ; for, in an im portant sense, the cross may be found in nature, and nature in the cross. But, after all, the tendency of the age is to substitute that which is artificial for that which is natural. Hence it is, that the Christian passes with indifference the works of God, while his soul rouses and his eye brightens when it turns to the works of man. O, what a magnificent temple it is which Jehovah has made our dwelling place ! It is a vast whisper ing gallery, echoing and reechoing with his name and his praise. How much do they lose who always have its vast 128 SPECIAL DIVINE INTERPOSITIONS IN NATURE. dome above them, and its lofty columns around them, and yet hear none of those whispers or echoes, nor feel any of the inspiration of the place, but whose supreme attention is de voted to " the gewgaws and trinkets, the puppet shows and histrionic feats, which fashion, and ambition, and sensuality have surreptitiously introduced there ! " How insensible lo every noble impulse has his heart become who has neither eye nor ear for the charms of Nature ! For she is the kind mother of us all. In her arms were we cradled, on her bosom were we nursed, and her voice falls on every well- attuned ear like the music of heaven. It is indeed the mu sic of heaven ; for Nature's harmonies are but a transcript of the divine perfections, and her voice is, therefore, the voice of God. We fear, however, that such sentiments do not accord with the experience of most Christians. They look upon the sys tem of nature as a field well adapted to regale the fancy, gratify the taste, and delightfully exercise the understanding, but not to warm the heart and feed the spiritual taste of piety. Creation is, indeed, a splendid temple, but it is cold and life less. No sacred fire burns upon the altar ; no crucified Redeemer is there to fix the attention and absorb the affec tions ; no Spirit of grace speaks gently to the soul. The religion of sentimentalism may flourish by communion with nature ; but the piety that saves the soul and blesses the world must seek for its nourishment at the foot of the cross. True, it is at the cross we must learn how to be saved, and how to save others. But because we cleave with supreme affection to the God of redemption, must we abjure the God of nature ? If it. feed our devotion to muse on the character of that God who devised and executed the marvellous plan of redemption by a long series of miracles in human history, SPECIAL DIVINE INTERPOSITIONS IN NATURE. 129 « shall it afford no nourishment to our new-born nature to find that the Author of this vast universe has interposed, in a no less special and wonderful manner, to fit up this world that it might become a proper theatre for the display of redeeming love ? Is there not something wrong in our hearts, if we do not recognize the same wonder-working, beneficent God in the natural as in the moral world ? Creation and redemption are but parts of one great system, and we may not disjoin what God has united ; neither may we depreciate one part of the scheme in order to exalt the other. We will try to unite them in our experience, as well as in our judgment. Then shall we see the same great truths imprinted upon nature which shine forth in 'redemption. Then shall all our com munion with nature serve only to strengthen our love of the cross, while the more powerfully we are constrained by the love of Christ, the more delightfully and profitably shall we wander among the works of God. O, how meagre is his en joyment of creation's beauties who looks at them with only the eye of the cold, calculating philosopher, or the mere en thusiasm of the poet, but not with a Christian's heart ! It is only such a heart that can vivify the scenes of the natural world with the presence of God. Nature has charms, in deed, for the mere man of taste, and of philosophy. But it is not till we bring in the religious element, that the affection becomes such as God would have it, a pure and a sanctifying emotion. It is no wonder that such a love as this should be a deep fountain of happiness in every condition of life. It does not, like almost all earthly affections, become weaker with ad vancing life, when the pressure of cares, disappointments, and the infirmities of old age come upon us. The man may be come weary of the world, and be deserted by it. Feeble 130 SPECIAL DIVINE INTERPOSITIONS IN NATURE. health may infuse wormwood into the common pleasures of life ; treachery and ingratitude may convert professed friends into enemies, and pierce his heart with many a pang ; and old age, with its failing senses and failing powers, may deaden his sensibilities to almost every thing else ; but if in early life a religious love of nature has taken possession of his soul, he will ever find it a sweet solace in the hour of desertion and bereavement; and, even amid the frosts of old age, the sacred flame, less bright only than his immortal hopes, shall spread a sweet light along his dark passage to the grave. Such a view of nature as this was taken by the writers of the Bible. The labored distinctions which we make between common and miraculous events were unknown to them. In every event they saw and joyfully recognized God's hand ; and hence it so often happens that the sentence which begins with praise to the God of nature ends with ascriptions of glory to the Redeemer. Nor is this all ; for these same views of this subject are taken in heaven. For the redeemed from among men, as they stand upon the sea of glass, and sing the song of Moses and the Lamb, exclaim, " Great and marvellous are thy works, Lord God Almighty.'" Yet these ransomed ones are ever ready to join in what seems the common chorus of heaven : " Blessing, and honor, and glory, and power be unto Him that sitteth upon the throne, and unto the Lamb forever and ever.'''' In heaven, therefore, at least, will the God whom science describes be identified with the God of redemption. Would that it were so on earth ! It will be, when educated men, especially ministers of the gospel, shall have fully de veloped the harmonies between nature and revelation. Here, then, is an object, second only to that of the personal salva tion of men, inviting the labors of those who go forth, after SPECIAL DIVINE INTERPOSITIONS IN NATURE. 131 long years of preparation, from our theological seminaries, burning with the desire to do what they can for the good of man and the glory of God. The field is open and inviting, and the ripening grain abundant. May those who take the sickle have a large share in so noble a work, and late in life return, bringing their sheaves with them. THE WONDERS OF SCIENCE COMPARED WITH THE WONDERS OF ROMANCE. Ladies and Gentlemen : The whole number of works, original and reprinted, that were published in the United States during the year ending with June, 1834, was 623. Of these, 126, or about one fifth, were novels and tales. In Great Britain, 1112 works were published in the year 1833 ; of which 71, or about one fifteenth, were novels and tales. In France, during the same year, 7011 works were issued; of which 355, or about one twentieth, were novels and tales. I have not been able to obtain a complete correspondent statement for any year subsequent to 1834. The following numbers, however, from the American Publishers' Circular for April, 1856, show a great increase of works of fiction. " In all departments, except that of fiction," says Mr. Norton, " there were published in this country, in the year 1855, about 800 different works ; adding for the new and old novels that owed birth or resuscitation to this year, the new issues will reach, in round numbers, to two thousand." This makes the works of fiction three fifths of the whole. These numbers afford some criterion of the taste of the reading part of the community in the countries specified. And what I wish particularly to be noticed at this time is, the much greater demand in this country for works of fiction (132) THE WONDERS OF SCIENCE AND ROMANCE. 133 than in Great Britain or France. Were I to include poetry in the list, however, it would swell the works of imagination in France to one ninth of the whole, and in Great Britain to one seventh ; while the poems published in this country during the same time were not numerous enough to alter the propor tion above stated. But it is to novels and tales that I wish to confine my attention. For very few of the injurious effects supposed to result from romances can be charged upon poe try, especially if it be not read in connection with romances. I think I may safely draw the inference, from the facts stated, that our countrymen show a very strong predilection for a light and fictitious literature. And I might add other evidence, were it needful. It would be shown in the register of every circulating library, as it is in almost every public original exhibition in the college and the academy. Young men, in such a case, will select those subjects in which they feel the most interest ; and how much more common is it, on such occasions, to hear discussed the character and merits of writers who address chiefly the fancy, than those who develop the substantial principles of accurate science and philosophy 1 It is seen, also, in the character of a large part of our peri odicals, which their editors scarcely dare send forth to the public, if not set off with one or two original tales. Except ing a few business newspapers in our larger towns, most of our hebdomadals also must be adapted in the same way to the public taste ; and the amorous story often stands in singular jux taposition with the solemn realities of practical religion in the adjoining column. But the taste of all classes must be suited.* * Yet it would he hut an act of justice to readers that the motto for such newspapers should be, in the words of Burns, — " Perhaps it may turn out a song, Perhaps turn out a sermon." 12 134 THE WONDERS OF SCIENCE COMPARED And last, though not least, our religious literature must be clothed in the drapery of fiction, or it will be passed by as old-fashioned and uninteresting ; while the latest religious romance will be seen occupying a conspicuous place upon the centre table. Nor will the devoted Christian — devoted, at least, to this kind of reading — suffer sleep to close his eyes, till it has been read through, and the enchanting story, if not the religion of the book, is deeply lodged in his memory. But it is not my object at this time to go into a detailed exposure of the evils of novel reading. Suffice it to say, that when the father learns that his son, who is in a course of public education, has become devoted to this kind of literature, he abandons the hope that he will ever rise higher as a scholar than to become a writer of tales for some newspaper or peri odical, or possibly the author of a play, that shall at least once appear upon the boards of Thespis. Or if his son be destined for business, instead of learning, the father expects that remissness and effeminacy will take the place of manly enterprise and success. The mother, too, who finds her daughter, in spite of all her warnings and rebukes, given up to secret midnight communings with the latest romance, almost abandons the hope of ever interesting her in those domestic pursuits that have always been the glory of New England women, or even in the higher and purer branches of literature. Indeed, she will be thankful if her daughter, in the ebullition of some glowing fancy scene, does not evapo rate into ether, and pass into that place described by Milton, — " All these, upwhirled aloft, Flew o'er the back side of the world, far off, Into a limbo, large and wide, since called The Paradise of Fools : — to few unknown Long after." — WITH THE WONDERS OF ROMANCE. 135 But I forbear : for I repeat that I have no intention of mak ing a direct attack upon the passion for romance that has taken so deep a hold upon the community ; and I beg pardon if any should be led, from my remarks, to fear a transmigration into the limbo of Milton. I wish to look at the fact, that so gen eral a taste for romance exists, with the eye of a philosopher ; and to inquire what that strong, deep-rooted principle of hu man nature is, that lies at the foundation of this taste. And although I doubt not that some are attached to romances be cause their baser passions there find fuel to inflame them, yet I prefer to believe, in general, that this taste has a nobler origin, and results from that strong love for whatever is new and wonderful, which is found in every human bosom, — es pecially in the morning of life. That desire was given us for wise purposes. Whenever it is suffered to waste itself upon fiction, it is perverted ; and what was intended for our happi ness becomes our bane. God has filled this beautiful world with enough of thrilling realities to feed and gratify this pas sion to the utmost, through the whole course of our pilgrim age. Passing by all other sources whence it may receive gratification, I request the attention of this audience — es pecially the youthful part of it — to some of the wonders developed by modern science. My object is to convince my hearers, that here is a far wider and nobler field, and a pro fusion of more delicious fruit, and sparkling gems, than fiction can offer. My hope is, that I may thus divert the attention of some who have begun to sip of the Circrean cup of ro mance, to the pure Castalian fountains of science, where the sparkling nectar of truth rises up to meet them. But in exhibiting the wonders of science, where shall I begin ? The field is immense : it is the universe ; and it is all filled up with wonders ; and the more critically these 136 THE WONDERS OF SCIENCE COMPARED are examined, the more do they multiply and enlarge. It must be, therefore, only a glance that we can now take. I feel like the man whohas undertaken to exhibit in one short hour the mazes and the beauties of an extensive series of gardens and parks, where the labor of centuries has been expended in collecting, arranging, and ornamenting the fruits and the flowers of every clime, and in forming every variety of alley, terrace, and arbor, of cascade, lake, and fountain. The conductor, as he hurries his visitors through one enchant ing and mazy spot after another, can only pluck here and there a flower, or point to the clustering fruit, or to some charming landscape. This is all I can hope to do, as we move at railroad speed through the wide fields of science. I begin with the science of mind, which, although abound ing in unprofitable speculation, still presents us with many important and wonderful truths. There is reason to believe, for instance, that no idea which ever existed in the mind can be lost. It may seem to ourselves to be gone, since we have no power to recall it ; as is the case with the vast ma jority of our thoughts. But numerous facts show that it needs only some change in our physical or intellectual con dition to restore the long-lost impression. .A servant girl, for instance, twenty-four years old, who could neither read nor write, in the paroxysms of a fever, commenced repeating fluently and pompously passages of Latin, Greek, and He brew ; and it afterwards appeared, that in her early days a learned clergyman, with whom she lived, had been in the daily habit of walking through a passage in his house that opened into the kitchen, and repeating aloud the very passages which she uttered during her fever. How many interesting infer ences crowd upon the mind in view of such facts ! What an amazing power do they prove to exist in the soul ! And what WITH THE WONDERS OF ROMANCE. 137 astonishing developments will be made in this world or an other, when the vast magazine of thoughts within us shall be unsealed ! And who can avoid the inquiry, what kind of thoughts he is daily pouring into this storehouse ! The capacity of the human mind for knowledge is another of its wonderful powers. By every accession of knowledge is that capacity enlarged ; nor have the limits of that expan sion ever been reached, or imagined. Indeed, the nature of the mind leads us to the conclusion that there are no limits. And it has already been shown that whatever knowledge the mind acquires it can never lose. What a magnificent con ception, to attempt to follow the mind along the path of its immortal existence, and to see it forever drinking in the stream of knowledge, whereby it constantly accumulates strength, and has- the sphere of its capacity enlarged, yet remaining eter nally infinitely inferior to the Deity ! Yet who can conceive of the vast amount of knowledge it will ultimately attain, or its more than angelic intellectual might ? No less wonderful is man's capacity for happiness. Here too we find no limits but infinity. The happy emotions of to day only qualify the soul for stronger emotions to-morrow, provided all the strings of the delicate instrument are in tune. Nor is the increase in an arithmetical, but in a geometrical ratio. Who shall set limits to the expanding series ? or who will doubt but God can fill to overflowing the most enlarged capacity through eternal ages ? Alike unlimited is man's capacity for misery. In this world his sufferings sometimes rise to a fearful height. Nor can we discover in the nature of mind any reason why an increase of knowledge should not add a proportionate intensity to suf fering. Who can tell what fountains of misery may be broken up, or when, in the round of eternal ages, the angry billows 12* 138 THE WONDERS OF SCIENCE COMPARED shall cease to roll over the soul that has broken loose from the great law of rectitude and happiness ? O, it is not strange that an inspired writer should declare, that man is not only wonderfully but fearfully made. His unlimited capacity for misery is surely a most fearful trait in his intellectual consti tution. Not less fearful is the supremacy that is given to Conscience in his moral nature, especially when we recollect with what unbending severity she applies her scorpion lash upon the soul that has fallen under her displeasure. Yet no less promptly does her approving voice cheer the soul that is struggling along the strait and narrow path of duty, and brings down into the heart the spirit of heaven. In short, to the mas tery of conscience every one must sooner or later submit. Rightly has it been called God's vicegerent in the soul ; and though it be a part of ourselves, we can as easily annihilate the soul as to escape from its dominion. And when we think how terrible are its inflictions sometimes upon the guilty, and recollect our unlimited capacity for misery, we cannot but in quire with solicitude whether its commission does not extend to another world ; and though an affirmative answer may shock the ear of guilt, it will make the heart of virtue beat high with delightful anticipations. Even this slight reference to some of the powers of the hu man soul show that it is a maze of wonders. What is there in the boldest flights of imagination to compare with it ? Here then the ingenuous mind can find enough to feed its strongest love of the new and the wonderful, without the aid of ro mance. Another department, no less interesting, is mathematics. And in the entire certainty of its conclusions it possesses an advantage over every other branch of knowledge. I know WITH THE WONDERS OF ROMANCE. 139 that it is not uncommon to speak of mathematics as a dry study ; but it is dry only for the reason that the grapes were sour to the fox — because he could not reach them. The truth is, that to those who have the resolution and persever ance to master its noble truths, it becomes one of the most fascinating of all pursuits. This is particularly true of the higher and more difficult parts of the subject — those sublime heights where your own fellow-citizen, the prince of Amer ican mathematicians,* soared so high, and gathered so many laurels, which he wreathed around the very cycles of the heavens. It is said that he who has the strength of wing to carry him fairly into the ethereal regions of the differential calculus, often becomes more fascinated than men in any other pursuit. So many new and unthought-of truths flash upon his mind, as he follows the golden thread of demonstra tion, that he seems to breathe an atmosphere almost freed from the grossness of earth. In such pursuits we can easily believe the English mathematician sincere when he exclaimed, Crede mihi, extingui dulce erit mathematicarum artium stu dio — "Believe me, it will be sweet to die in the study of mathematics." But though mathematics be full of curious and fascinating truths, yet such is the nature of the subject that I shall scarce ly be able to clothe even one fair example in a popular dress. Let me attempt one or two founded upon the doctrine of infinitesimals. To one who has not thought on the subject this. proposition seems not a little paradoxical, viz., that a man may approach nearer and nearer to a fixed object eternally, and yet not be able to reach it ; yet by slackening his pace in a certain ratio, the result would be that he could never reach * Dr. Nathaniel Bowditch, formerly a resident of Salem, where this lec ture was first given. 140 THE WONDERS OF SCIENCE COMPARED the object, although he might make an infinitely near approach to it. Another proposition may be new to some, and worthy of being named. It is this : two lines may approach nearer and nearer forever without meeting, — the asymptote to the hyperbole, for example. This, too, is very easily conceived, though likely to produce scepticism when first announced. A third proposition asserts that one infinitesimal may be infinitely smaller than another. Here the mathematician starts with something infinitely small, — for that is the meaning of an infinitesimal, — and he asserts that another thing may be infinitely smaller. And this he demonstrates. How stupid must that intellect be which is not roused and interested by such paradoxes ! The science of moving forces, or mechanics, abounds with principles and demonstrations that are novel and striking to the beginner. But for the reasons mentioned in speaking of mathematics, they cannot be now exhibited. Perhaps the fol lowing proposition may at least be amusing, although it can hardly be regarded as true, except theoretically. Any force, however small, can put in motion a body however large, and by a sufficient number of repetitions, give it a velocity infi nitely great. When, for instance, a man stamps with his foot, he moves the earth ; and could he prevent the reaction of gravity, and were to continue to stamp long enough, he would not only put the earth in motion, but give it a velocity greater than it now has in its orbit. But the nov cttoj, the place to stand on, which Archimedes demanded, can never be ob tained ; and therefore this experiment can never be tried. The mechanical properties of fluids, and especially of the atmosphere, are some of them of a remarkable character. Light and yielding as we regard the air, what but experiment WITH THE WONDERS OF ROMANCE. 141 would satisfy us that a musket ball, that has a velocity suf ficient to range seventeen miles in a vacuum, actually falls short of half a mile ; and that so rapidly does the resistance increase with the velocity, that it would become at length so great that a ball would be stopped as if fired against a* stone wall ! Another property of fluids that leads to some singular re sults is their power of pressing in all directions alike. Hence it becomes true that, any quantity of a fluid, however small, will balance any quantity, however large. Hence the hydro static bellows ; by standing on which and blowing forcibly into a tube, a man may raise himself from the floor — or still more certainly by pouring into that tube a single pint of wa ter. Hence, too, by inserting a tube, not more than the tenth of an inch in diameter, in the strongest vessel filled with wa ter, and then making the tube sufficiently strong and pouring water into it, the vessel may be burst ; that is, the weight of a single quart of water is sufficient to burst asunder an iron- bound vessel. Or by fitting a strong piston to a large cylinder, the powerful machine called the hydrostatic press is formed, by which trees are torn up by the roots, porous bodies aston ishingly compressed, and enormous weights elevated. This same principle (of equal pressure in all directions) prevents us from being conscious of the great weight of the atmosphere. Indeed, we are not aware that any pressure is upon us ; and unless we move very rapidly, or against a strong wind, we scarcely realize that the air offers any resistance. Hence a man unacquainted with pneumatics can hardly be made to believe that every square inch of surface upon his body does in fact sustain a weight of fifteen pounds, and that the whole weight of the atmosphere that lies upon him is not less than fourteen and a half tons ; while the whole sur- 142 THE WONDERS OF SCIENCE COMPARED face of the earth sustains a pressure of twelve trillions of pounds, or six thousand billions of tons. The extent to which matter may be divided, both mechan ically and chemically, may be regarded as one of the wonders of modern science. Little, indeed, is said at this day respect ing the infinite divisibility of matter ; which, if theoretically possible, is now generally regarded by philosophers as in re ality untrue. With Sir Isaac Newton, they now mostly con sider it " probable that God in the beginning formed matter in solid, massy, hard, impenetrable, movable particles, of such sizes and figures, and with such other properties, and in such proportion to space, as most conduced to the end for which he formed them." These ultimate particles are called atoms ; and although none of them have ever been rendered cognizable by the senses, yet it can be shown that they must be inconceivably small. Gold may be spread over silver wire so thin that fourteen million films of it would make a pile only one inch thick ; while fourteen million films of common writing paper would form a pile three quarters of a mile thick. Gold may be beaten so thin that one twenty millionth part of a grain is visible to the naked eye, and one fourteen hundred millionth part through a microscope. Yet in each of these fragments there may be, for aught we know, millions of atoms. A cer tain species of fungus, (bovista giganteum,) has been known to attain the size of a gourd in one night ; and it is calculated that the cellules, of which it is composed, must amount to 47,000,000,000. If it grew in twelve hours, this would give 4,000,000,000 per hour, or more than 66,000,000 each min ute. Animalcules have been discovered so small that 1,000,- 000 would not exceed a grain of sand, and 500,000,000 could sport in a drop of water. Yet each of these must have blood- WITH THE WONDERS OF ROMANCE. 143 vessels, nerves, muscles, circulating fluids, &c, like larger animals. What, then, must be the almost infinite littleness of a particle of these fluids ! Yet chemical solution carries this division of matter probably still farther. Thus it has been demonstrated that an atom of lead must weigh less than the one three hundred and ten thousand millionth part of a grain, and an atom of sulphur less than the one two trillionth part of a grain. The bulk of the atom of lead must be less than the eight hundred and eighty-eight trillionth part of a cubic inch. But it seems almost useless to make such statements ; for who can form any correct idea of things so inconceivably minute ? * If, however, we regard light as a material substance, results still more astonishing follow. It can be shown that, in such a case, the particles of light cannot weigh more than one million millionth part of a grain ; for if larger, they would destroy the organs of vision.f On the same principle, it has been calculated that the particles of light that flow from a candle in a second are more than six billion times as many as the grains of sand in the whole earth, if each cubic inch contains one million.^ The opinion that light is material, however, has given place to what is called the undulatory theory. This supposes the universe to be filled with a very subtle elastic fluid, called the luminiferous ether, and that the vibrations of this ether communicate the impression of light to the eye just as the vibrations of the air convey to the ear the idea of sound. But, upon this hypothesis, the inferences are no less wonderful than upon the supposition that light is material. It is a demonstrated fact, for instance, that light moves at the rate of nearly 200,000 miles (192,500) per * Prout's Bridgewater Treatise, p. 36. f Turner's Sacred History, Vol. I. p. 24. % Ferguson's Lectures, Vol. I. p. 228. 144 THE WONDERS OF SCIENCE COMPARED second ; and who can conceive of vibrations spreading on all sides of a luminous body with such a velocity ? Take, for an example, one of the fixed stars. Astronomers have demon strated that the distance of the nearest star cannot be less than twenty billions of miles, while stars of smaller mag nitude must be situated at a distance immensely greater. Now, it has been shown by Dr. Wollaston that the light of Sirius is only one twelve thousand millionth part (11,839,- 530,000) as great as the light of the sun ; and the light of the star Vega, of much smaller magnitude, is 180 millions of times less than that of the sun. Yet, if the eyes of the ten thousand millions of animals on the globe were all turned towards this star at the same instant, each one would have a distinct image of it formed upon the retina. And if the mil lions of millions of other worlds, scattered through space, are peopled as thickly as our own, and every eye there were directed to that star at the same time, each eye would see it as distinctly as if no other one were gazing upon it. What an astonishing power, then, is light ! Who does not feel him self lost in attempting to comprehend its nature ! But, still further, philosophers suppose they have demon strated that the different colors in nature are produced by a difference in the number of vibrations in the luminiferous ether, and that, in a single second of time, the eye is affected by these movements as follows : — In red, . . 477,000,000,000 of times ; In orange, . 506,000,000,000 of times ; In yellow, . 535,000,000,000 of times ; In green, . 577,000,000,000 of times ; In blue, . . 622,000,000,000 of times ; In indigo, . 658,000,000,000 of times ; In violet, . 699,000,000,000 of times. WITH THE WONDERS OF ROMANCE. 145 Is it strange that man looks upon light with an awe ap proaching devotion, and that Milton should exclaim, — " Hail, holy light ! offspring of Heaven, first born, Or of the eternal, coeternal beam " ? I will only add, in this connection, a statement of La Place respecting attraction : " I have ascertained," says he, " that between the heavenly bodies all attractions are transmitted with a velocity which, if it be not infinite, surpasses several thousand times the velocity of light." His annotator esti mates it as eight million of times greater than that of light. Were there time for the details, the science of optics would furnish many other illustrations appropriate to my object — such as the diffraction of light, the splendid colors of their films, and the phenomena of polarization and double refrac tion. But I must hurry forward. Nor can we be long de tained even upon the sublime developments of astronomy. Since the most common and striking of these have been so often and familiarly described in public lectures, and even in the primary school manual, I shall confine my remarks to some principles that are less generally known, or to recent discoveries. I have always regarded it as one of the greatest achieve ments of astronomers that they have been able to weigh the bodies of the solar system, so as to state how many pounds avoirdupois they contain, and to ascertain their relative weight compared with that of water. It is certain, for instance, that the mass of Jupiter is more than 322, and less than 323, times the mass of this globe — so accurately has this work been accomplished. The mass of the sun is 359,551 times greater than that of the earth and moon, and 700 times greater than the united masses of all the planets. The 13 146 THE WONDERS OF SCIENCE COMPARE!) weight of the most important bodies of the solar system, com pared with water, is as follows : — Sun, . . . 1.40 Mars, . . 0.71 Moon, . . 3.37 Jupiter, . . 1.42 Mercury, . 15.24 Saturn, . . 0.56 Venus, . . 5.15 Uranus, . 1.53 Earth, . . 5.48 From this statement we learn that Saturn is composed of matter only half as heavy as water; while Mercury is consid erably heavier than quicksilver, and a third heavier than lead. Our own globe, also, taken as a whole, is twice as heavy as common rock, and half as heavy as lead — a fact which shows the great density of its internal parts. The disturbances that take place among the heavenly bodies in consequence of their mutual attraction constitute a branch of knowledge the most profound, it is said, in the vPbole circle of human science — requiring all the aid of the most difficult and subtle mathematical analysis. In this field such men as Newton and La Grange, La Place and Bowditch, have won their noblest honors ; and I may add, it is only such minds that can disentangle the mazes of this labyrinth. The problem to be solved was this : given the directions and velocities of about thirty mutually-attracting bodies, to find their places after any number of ages. And to give some idea of the complexity of the problem, it may be stated that one of these bodies, the moon, is subject to no less than sixty perturbations in her longitude. And to show how successful astronomers have been in estimating these, it may be stated that the lunar tables actually contain twenty-eight corrections, or equations, to be applied to her mean place to obtain her true place ; and the result never varies from the truth more WITH THE WONDERS OF ROMANCE. 147 than five seconds of a degree. But the most interesting re sult to which these investigations have led is the great truth, that, in spite of these perturbations, the permanence of the solar system is secured ; nay, that these very disturbances are the means of preserving it from ruin. Formerly, astron omers thought they saw in the motions of the heavenly bod ies a tendency to ruin. The moon, for instance, has been for thousands of years coming nearer and nearer the earth in every revolution ; and the eccentricity of the earth's orbit has been diminishing, as has also the obliquity of the ecliptic to the equator. * But it is now shown that all these irregularities are periodical ; and that after having proceeded in one direc tion for a time, — it may be for hundreds, or thousands, or even millions of years, — they will reach a limit which they cannot pass, and oscillate in the opposite direction ; and the limits of oscillation are too narrow seriously to affect the sta bility of the system or the comfort of its inhabitants. This demonstration, first wrought out by La Grange and La Place, and afterwards corrected by Bowditch, is one of the proudest achievements of modern science, and proves that our system, in itself considered, is eternal. But a question has long been agitated whether all space is not occupied with very thin and subtle matter, which must offer a resistance to the motions of the heavenly bodies, and bring the system to ruin at last. And modern astronomical discoveries seem nearly to have settled this question in the affirmative. The universal diffusion of light, heat, and elec tricity, especially if the undulatory theory of light be true, render such an opinion probable. But the observations that have been made upon what is called Encke's comet, which revolves round the sun in three and a half years, make it almost certain that this medium does exist. That comet, 148 THE WONDERS OF SCIENCE COMPARED being nothing but a mass of thin vapor, is retarded much more than the planets, which are solid, and has actually ad vanced in its orbit, since its discovery, ten days more than can be explained by the laws of gravity, exclusive of a resisting medium. Some thirty thousand years will elapse before it will fall into the sun, and many millions of years before the same cause would precipitate the planets to the centre ; but it is an interesting conclusion that, ultimately and inevitably, if such a cause exist, ruin must ensue. Modern discoveries respecting the nature of comets in gen eral open a wide field for the play of the imagination. It seems now to be proved that nearly all of them (say, perhaps, 800) are nothing but thin vapor ; for the fixed stars are visi ble directly through their centres. They must, of course, be far less dense than the thinnest cloud. And yet these bodies move round the sun in obedience to the same laws as the planets, though liable to greater irregularities. The trains which accompany them, and which are sometimes, as in the comet of 1811, more than 130 millions of miles long, are evidently produced by the action of the sun, but in what way it seems difficult to conceive. In all ages, great anxiety has been manifested lest a collision should take place between the earth and one of these bodies. But the knowledge we now have of their nature teaches us that, even should one of them be encountered in the earth's annual circuit, it is not probable that matter so tenuous could pass through the atmosphere, and that the only effect of such an occurrence would be some slight meteorological change, or perhaps, as one of our coun trymen suggests, who has distinguished himself by attention to this and kindred subjects, another splendid meteoric shower might signalize the event.* * Olmsted's Astronomy, p. 242. WITH THE WONDERS OF ROMANCE. 149 The comet called Biela's, from its discoverer, which re volves around the sun in»about seven years, in one of its recent returns, divided into two parts, which moved on together, with no apparent mutual influence. This fact proves, if proof were wanting, the extreme tenuity of the matter. The parts move along together just like two wreaths of smoke or. vapor, and have occupied the same relative position for at least one revolution, except that they are receding from each other. So successful have Lord Rosse and others been in resolv ing nebula?, of late, that some astronomers are confident that all of them will be found, at length, to consist of stars. But such masses as the Magellanic Clouds of the southern hemi sphere, and especially the facts respecting spiral nebula?, make it more probable that some of them consist rather of diffused patches of self-luminous vapor, analogous to comets. On the hypothesis that they are made up of fixed stars, it is quite impossible to account for their spiral form. But if the mat ter has been in motion in a resisting medium, it would have assumed a spiral form, and be disseminated all along its course towards the centre of attraction. The curious facts that are established by modern astrono mers respecting double stars prove that the great law of grav itation extends to other systems beyond the solar. More than one quarter of the stars, according to Struve, are double ; and, in several instances, it is proved that these stars revolve about each other in elliptic orbits, in periods between 43 and 1200 years. Taking these facts in connection with the periodical disappearance and reappearance of some stars, with th
