SUPPLEMENT TO THEOLOGY AND THE SCIENCE OF aOVERNMENT. ON THE RATIONALISM OF METAPHYSICS. Being a review of a book called Kant's Oritique of Pure Reason*. In noticing this book, bringing it again, perhaps, prominently before the public, and calling attention particularly to certain passages in it ; we do so under protest. We protest against any supposition that the book in a correct sense belongs to science ; or that it has in itself any value to recommend its reconsideration by the public. On the contrary, we hold it to be a harmful, baneful book which has been and still is, directly and indirectly, potent for mischief. In examining and objecting to this book, however, it is not to it only, but to the class of books, doctrines, and opinions which belong to it and to which it belongs. We do not suppose that the ordinary student, of the man of ordinary education, is in much risk of directly con- founding himself by the serious endeavour to study and comprehend this work as a part of legitimate science. We feel sure that the perusal of a few pages by a person whose mind is in a naturally healthy condition must usually produce a degree of mental nausea suiiicient to protect the ordinary individual from direct injury ; but it by no means follows that such person is not indi- vidually interested in the book, and that he may not receive injury of the most serious description from it. * Critiqne of Pure Reason, ] Translated from the German BT IMMANUBL KaHT, j g^ j jj_ p_ MeiklejohD. Henry G. Bohn, London, 1860. 4 THE EATIONALISM OF METAPHYSICS. Let US consider, with some attention, one way out of several in which he may receive serious injury. A teacher of some department of knowledge, such as physical science, has by the evidence of superior ability, by the clearness- of his explanations, by his sincerity, in- dustry, skUl and sagacity, gained the confidence of a number of persons, it may be, of all the members of a scientific society, or, perhaps, his reputation may have ex- tended throughout the town or, even, the whole country to which he belongs, or, it may be, that he has earned a world-wide renown, and his name has become re- cognized throughout the world of education and civi- lization as of a man whose teaching is authoritative, whose credentials are such as to place his propositions almost above controversy, and such that his certified examination and approval of a doctrine is sufficient of itself to strongly recommend to the student the accept- ance of that doctrine. Let us suppose that such teacher has directed his attention especially to one department of Natural Science, to physics, for instance, or some other one department, but has investigated and acquired knowledge in other departments of Natural Science also. Having attained his reputation as a teacher of great ability, he becomes desirous to still further extend the area of his knowledge and thereby his ability to instruct : and he proceeds to commence the study of Ideal Science, to which he has hitherto paid scarcely any attention. Now comes the important question. . . Does his science securely rest upon the fundamental basis of sound science ; that is, upon the primary facts of natural and revealed theology ? If not, we say that such an one is in even greater dan- ger than the intelligent young lad eager for the acquisi- tion of knowledge whose mind is allowed to wander, un- , guided and unprotected, amongst the snares and pitfalls of unsound ideal science. When such a man brings his mind deliberately to the consideration of some system THE RATIONALISM OF METAPHYSICS. 15 ■5of metaphysics, whether it be a modification of Kant's transcendental system or some other, he will not allow 'his mind to be repelled from the study by a mere repug- Tiance or distaste in the first instance. And besides, his previously acquired knowledge and experience spares him the necessity of much of the labour which would have to be undergone by the inexperienced student, for the latter to assimilate the strange doctrines, and to become possessed of them as apart of his own knowledge. But the man is a justly renowned teacher. The false and mischievous doctrines, having mingled in the alembic of his mind with the truths and facts of Natural Science, do jQot come forth in the same nauseous state in whicli they are presented in such a work as Kant's Critique ; they now have all the advantages of the persuasive speech, trained skill, earnestness and experience of the teacher himself, and thus the noxious doctrines, disguised by ■truths to which they seem to belong, are rendered accep- table to the unguarded mind of the student. We will commence with an analytical examination of that which, assuming the work to have any pretension to scientific arrangement, must be considered the com- mencement proper of the treatise. This will be found at page 212, under the following heading : " Of JPure Reason^ the seat of the Transcendentalllluso- ry appearance" A. • OF REASON IN GENERAL. " All our knowledge begins with sense, proceeds thence to under- standing, and ends with reason,' beyond which nothing higher can be discovered in the human mind for elaborating the matter of intuition and subjecting it to the highest unity of thought. At this stage of our enquiry it is my duty to give an explanation of this, the highest faculty of cognition, and I confess I find myself here in some difK- culty. Of reason, as of the understanding, there is a merely formal, that is, logical use, in which it makes abstraction of all content of 6 THE RATrOKALISM OF METAPHTBICS". cognition ; but there is also a real use, iiiasmuch as it containB- i» itself the source of certain conceptions and principles, which it does= not borrow either from the senses or the understanding. The- former faculty hsts been long defined by logicians' as the faculty of mediate conclusion in contradistinction to> immediate eonclusions- (consequeniicB immediatcB^) But the nature of the latter, which itself genera,tes conceptions,- is not to be understood from this de-- flnition . Now, as a division- of reason into a . logical and a tran- scendental faculty presents itself h«re, it becomes necessary to seek for a higher conception of this source of cognition which shall com- prehend both conceptions. In this we may expect, according to the- analogy of the conceptions of the understanding,, that the logical con- ception will give us the key to the transcendental,- and that the table- of the functions of the former will present us with the clue to the- conceptions of reason. " In the former part of our transcendental logicy we defined the- understanding to be the faculty of rules ; reason maybe- distinguished from understanding as the faeulty of principles, " The term principle is ainbiguous, and commou-ly signifies merely a cognition that may be employed as a principle ; albhough it is not. in itself, and as regards its proper origin, entitled to the distinction.. Every general proposition, even if derived from experience by the process Of induction, may serve as the major in a syllogism ; but it is not for that reason a principle. Mathematical axioms (for exampler there can be only one straight line between two points,) are general d priori cognitions, and are therefore rightly denominated principles, relatively to the cases which can be subsumed under them. But I cannot, for this reason, say that I cognize this property of a straight line from principles. I cognize it only in pure intuition. " Cognition from principles, then, is that cognition, in which I cog- nize the particular in the general by means of conceptions . Thus every syllogism is a form of the deduction of a cognition from a prin- ciple. For the major always gives a conception through which every thing that is subsumed under the condition thereof, is cognized according to a principle. Now, as every general cognition may serve as the major in a syllogism, and the understanding presents us with such general d priori propositions, they may be termed principles, in respect of their possible use. " But if we consider these principles of the pure understanding in T?Hi: NATIONALISM OF METAPHTSIOS. 7 Telation to their origin, we shall find them to be anything rather than ■cognitions from conceptions.' For they would not even be possible d, priori, if we could not rely on the assistance of pure intuition (in ■mathematics), or on that of the conditions of -a possible experience- That everything that happens has a cause, cannot be concluded from ■the general conception of that which happens ; on the contrary, the principle of causality instructs us as to the mode of obtaining from that which happens a determinate empirical conception. " Synthetical cognitions from conceptions the understanding cannot supply, and they alone are entitled to be called principles. At the ■same time, all general propositions may be termed comparative prin- .ciples. " It has been a long-cherished wish that, (who knows liow late) may ■one day be happily accomplished — that the principles of the endless variety of civil laws should be investigated and exposed ; for in this way alone can we find the secret of simplifying legislation. But in this case, laws are nothing more than limitations of our freedom upon conditions under which it ^bsists in perfect harmony with itself; they consequently have for their object that which is completely otir •own work, and of which we ourselves may be the cause by means of these conceptions. But how objects, as things in themselves — how the nature of things is subordinated to principles and is to be deter- xnined according to conceptions, is a question which it seems well nigh impossible to answer. Be this, however, as it may — ^for on this point our investigation is yet to be made — it is at least manifest from ■what we have said, that cognition from principles is something very •different from cognition by means of the understanding, which may indeed precede other cognitions in the form of a principle, but in itself —so far as it is synthetical — is neither based upon mere thought, nOr XJontams a general proposition drawn from conceptions alone. " The understanding may be a faculty for the production of unity .of phenomena by virtue of rules ; the reason is a faculty for the pro- duction of unity of rules (of the understanding) under principles. Reason, therefore, never applies directly to experience, or to any sen- suous object ; its object is, on the contrary, the understanding, to the manifold cognition of which it gives a unity d priori by means of conceptions — a unity which may be called rational unity, und which is of a nature very different from that of the unity produced by the •undsrstanding. 8 THE RATIONALIBM OP METAPHTSICSi " The above is the general conception of the faculty of reason, in so far as it has been possible to make it comprehensible in the absence' of examples. These will be given in the sequel." The very first part of the first sentence- " all our know- fedge begiiiK with sense "' appears' to' be in violer't contra- diction to the general teaching of the work, which sometimes assumes and' sometimes purports to demon- strate that knowledge is quite independent of sense,, and. that sense itself belongs only to one class- of effects ©r consequents, to which intuitions, conceptions, and cognitions, stand in the relation of causes or antece- dents. In the second part of this first sentence, '' proceeds thence to understanding; and ends with reason,"" beyond which nothing can' be discovered in' the human mind for elaborating the matter of intuition; understanding as a mental process or faculty is made to precede reason-. Now, this appears to be evidently erroneous in the sense which Kant indirectly attaches to those expressions-. Reason is described' as the mental process or a part of the process by which the matter of intuition is elaborated, but knowledge (all knowledge is necessarily compound,) whether it be in the form of a statement, proposition or conclusion,, cannot be understood unless its, elements be first arranged by the intellectual faculty of the inind. We neither affirm nor admit 1;hat there are any two such distinct processes as reason and understanding, as supposed by Kant ; but we say that the meaning of the term understanding, whether it be considered aprocess; a " faculty or anything else, imphes that it is subsequent to that process of the intellectual faculty by which the ele- ments of the knowledge are arranged, for it is not an in- coherent and disorderly collection of ideas, but the clear and distinct statement which is said to be understood as a cognition by the mind. When (compound) knowledge IS under stood;hjth.& mind, the whofe process of elaborafr- in
