Now if Kant, as he here pretends, and also apparently did in earlier cases, had merely inferred the thing in itself, and that with the great inconsistency of an inference absolutely forbidden by himself, what a remarkable accident would it then be that here, where for the first time he approaches the thing in itself more closely and explains it, he should recognise in it at once the will, the free will showing itself in the world only in temporal manifestations! I therefore really assume, though it cannot be proved, that whenever Kant spoke of the thing in itself, in the obscure depths of his mind he already always indistinctly thought of the will. This receives support from a passage in the preface to the second edition of the “Critique of Pure Reason,” pp. xxvii. and xxviii., in Rosenkranz's edition, p. 677 of the Supplement.
For the rest, it is just this predetermined solution of the sham third conflict that affords Kant the opportunity of expressing very beautifully the deepest thoughts of his whole philosophy. This is the case in the whole of the [pg 122] “Sixth Section of the Antinomy of Pure Reason;” but, above all, in the exposition of the opposition between the empirical and the intelligible character, p. 534-550; V. 562-578, which I number among the most admirable things that have ever been said by man. (As a supplemental explanation of this passage, compare a parallel passage in the Critique of Practical Reason, p. 169-179 of the fourth edition, or p. 224-231 of Rosenkranz's edition.) It is yet all the more to be regretted that this is here not in its right place, partly because it is not found in the way which the exposition states, and therefore could be otherwise deduced than it is, partly because it does not fulfil the end for which it is there—the solution of the sham antinomy. The intelligible character, the thing in itself, is inferred from the phenomenon by the inconsistent use of the category of causality beyond the sphere of all phenomena, which has already been sufficiently condemned. In this case the will of man (which Kant entitles reason, most improperly, and with an unpardonable breach of all use of language) is set up as the thing in itself, with an appeal to an unconditioned ought, the categorical imperative, which is postulated without more ado.
Now, instead of all this, the plain open procedure would have been to start directly from the will, and prove it to be the in-itself of our own phenomenal being, recognised without any mediation; and then to give that exposition of the empirical and the intelligible character to explain how all actions, although necessitated by motives, yet, both by their author and by the disinterested judge, are necessarily and absolutely ascribed to the former himself and alone, as depending solely upon him, to whom therefore guilt and merit are attributed in respect of them. This alone was the straight path to the knowledge of that which is not phenomenon, and therefore will not be found by the help of the laws of the phenomenon, but is that which reveals itself through the phenomenon, becomes knowable, objectifies [pg 123] itself—the will to live. It would then have had to be exhibited merely by analogy as the inner nature of every phenomenon. Then, however, it certainly could not have been said that in lifeless or even animal nature no faculty can be thought except as sensuously conditioned (p. 546; V. 574), which in Kant's language is simply saying that the explanation, according to the law of causality, exhausts the inner nature of these phenomena, and thus in their case, very inconsistently, the thing in itself disappears. Through the false position and the roundabout deduction according with it which the exposition of the thing in itself has received from Kant, the whole conception of it has also become falsified. For the will or the thing in itself, found through the investigation of an unconditioned cause, appears here related to the phenomenon as cause to effect. But this relation exists only within the phenomenal world, therefore presupposes it, and cannot connect the phenomenal world itself with what lies outside it, and is toto genere different from it.
Further, the intended end, the solution of the third antinomy by the decision that both sides, each in a different sense, are right, is not reached at all. For neither the thesis nor the antithesis have anything to do with the thing in itself, but entirely with the phenomenon, the objective world, the world as idea. This it is, and absolutely nothing else, of which the thesis tries to show, by means of the sophistry we have laid bare, that it contains unconditioned causes, and it is also this of which the antithesis rightly denies that it contains such causes. Therefore the whole exposition of the transcendental freedom of the will, so far as it is a thing in itself, which is given here in justification of the thesis, excellent as it is in itself, is yet here entirely a μεταβασις εις αλλο γενος. For the transcendental freedom of the will which is expounded is by no means the unconditioned causality of a cause, which the thesis asserts, because it is of the essence of a cause that it must be a phenomenon, and not something [pg 124] which lies beyond all phenomena and is toto genere different.
If what is spoken of is cause and effect, the relation of the will to the manifestation (or of the intelligible character to the empirical) must never be introduced, as happens here: for it is entirely different from causal relation. However, here also, in this solution of the antinomy, it is said with truth that the empirical character of man, like that of every other cause in nature, is unalterably determined, and therefore that his actions necessarily take place in accordance with the external influences; therefore also, in spite of all transcendental freedom (i.e., independence of the will in itself of the laws of the connection of its manifestation), no man has the power of himself to begin a series of actions, which, however, was asserted by the thesis. Thus also freedom has no causality; for only the will is free, and it lies outside nature or the phenomenon, which is just its objectification, but does not stand in a causal relation to it, for this relation is only found within the sphere of the phenomenon, thus presupposes it, and cannot embrace the phenomenon itself and connect it with what is expressly not a phenomenon. The world itself can only be explained through the will (for it is the will itself, so far as it manifests itself), and not through causality. But in the world causality is the sole principle of explanation, and everything happens simply according to the laws of nature. Thus the right lies entirely on the side of the antithesis, which sticks to the question in hand, and uses that principle of explanation which is valid with regard to it; therefore it needs no apology. The thesis, on the other hand, is supposed to be got out of the matter by an apology, which first passes over to something quite different from the question at issue, and then assumes a principle of explanation which is inapplicable to it.
The fourth conflict is, as has already been said, in its real meaning tautological with the third. In its solution [pg 125] Kant develops still more the untenable nature of the thesis; while for its truth, on the other hand, and its pretended consistency with the antithesis, he advances no reason, as conversely he is able to bring no reason against the antithesis. The assumption of the thesis he introduces quite apologetically, and yet calls it himself (p. 562; V. 590) an arbitrary presupposition, the object of which might well in itself be impossible, and shows merely an utterly impotent endeavour to find a corner for it somewhere where it will be safe from the prevailing might of the antithesis, only to avoid disclosing the emptiness of the whole of his once-loved assertion of the necessary antinomy in human reason.
Now follows the chapter on the transcendental ideal, which carries us back at once to the rigid Scholasticism of the Middle Ages. One imagines one is listening to Anselm of Canterbury himself. The ens realissimum, the essence of all realities, the content of all affirmative propositions, appears, and indeed claims to be a necessary thought of the reason. I for my part must confess that to my reason such a thought is impossible, and that I am not able to think anything definite in connection with the words which denote it.
Moreover, I do not doubt that Kant was compelled to write this extraordinary chapter, so unworthy of him, simply by his fondness for architectonic symmetry. The three principal objects of the Scholastic philosophy (which, as we have said, if understood in the wider sense, may be regarded as continuing down to Kant), the soul, the world, and God, are supposed to be deduced from the three possible major propositions of syllogisms, though it is plain that they have arisen, and can arise, simply and solely through the unconditioned application of the principle of sufficient reason. Now, after the soul had been forced into the categorical judgment, and the hypothetical was [pg 126] set apart for the world, there remained for the third Idea nothing but the disjunctive major. Fortunately there existed a previous work in this direction, the ens realissimum of the Scholastics, together with the ontological proof of the existence of God set up in a rudimentary form by Anselm of Canterbury and then perfected by Descartes. This was joyfully made use of by Kant, with some reminiscence also of an earlier Latin work of his youth. However, the sacrifice which Kant makes to his love of architectonic symmetry in this chapter is exceedingly great. In defiance of all truth, what one must regard as the grotesque idea of an essence of all possible realities is made an essential and necessary thought of the reason. For the deduction of this Kant makes use of the false assertion that our knowledge of particular things arises from a progressive limitation of general conceptions; thus also of a most general conception of all which contains all reality in itself. In this he stands just as much in contradiction with his own teaching as with the truth, for exactly the converse is the case. Our knowledge starts with the particular and is extended to the general, and all general conceptions arise by abstraction from real, particular things known by perception, and this can be carried on to the most general of all conceptions, which includes everything under it, but almost nothing in it. Thus Kant has here placed the procedure of our faculty of knowledge just upside down, and thus might well be accused of having given occasion to a philosophical charlatanism that has become famous in our day, which, instead of recognising that conceptions are thoughts abstracted from things, makes, on the contrary the conceptions first, and sees in things only concrete conceptions, thus bringing to market the world turned upside down as a philosophical buffoonery, which of course necessarily found great acceptance.
Even if we assume that every reason must, or at least can, attain to the conception of God, even without revelation, [pg 127] this clearly takes place only under the guidance of causality. This is so evident that it requires no proof. Therefore Chr. Wolf says (Cosmologia Generalis, prœf., p. 1): Sane in theologia naturali existentiam Numinis e principiis cosmologicis demonstramus. Contingentia universi et ordinis naturæ, una cum impossibilitate casus, sunt scala, per quam a mundo hoc adspectabili ad Deum ascenditur. And, before him, Leibnitz said, in connection with the law of causality: Sans ce grand principe on ne saurait venir à la preuve de l'existence de Dieu. On the other hand, the thought which is worked out in this chapter is so far from being essential and necessary to reason, that it is rather to be regarded as a veritable masterpiece of the monstrous productions of an age which, through strange circumstances, fell into the most singular aberrations and perversities, such as the age of the Scholastics was—an age which is unparalleled in the history of the world, and can never return again. This Scholasticism, as it advanced to its final form, certainly derived the principal proof of the existence of God from the conception of the ens realissimum, and only then used the other proofs as accessory. This, however, is mere methodology, and proves nothing as to the origin of theology in the human mind. Kant has here taken the procedure of Scholasticism for that of reason—a mistake which indeed he has made more than once. If it were true that according to the essential laws of reason the Idea of God proceeds from the disjunctive syllogism under the form of an Idea of the most real being, this Idea would also have existed in the philosophy of antiquity; but of the ens realissimum there is nowhere a trace in any of the ancient philosophers, although some of them certainly teach that there is a Creator of the world, yet only as the giver of form to the matter which exists without him, δεμιουργος, a being whom they yet infer simply and solely in accordance with the law of causality. It is true that Sextus Empiricus (adv. Math., ix. § 88) quotes an argument [pg 128] of Cleanthes, which some have held to be the ontological proof. This, however, it is not, but merely an inference from analogy; because experience teaches that upon earth one being is always better than another, and man, indeed, as the best, closes the series, but yet has many faults; therefore there must exist beings who are still better, and finally one being who is best of all (κρατιστον, αριστον), and this would be God.
