СКАЧАТЬ in the passages quoted, the assumption of Kant here criticised will be found expressed with admirable clearness in the “Critique of Judgment,” § 36, just at the beginning; also in the “Metaphysical Principles of Natural Science,” in the note to the first explanation of “Phenomenology.” But with a naïveté which Kant ventured upon least of all with reference to this doubtful point, it is to be found most distinctly laid down in the book of a Kantian, Kiesewetter's “Grundriss einer algemeinen Logik,” third edition, part i., p. 434 of the exposition, and part ii., § 52 and 53 of the exposition; similarly in Tieftrunk's “Denklehre in rein Deutschem Gewande” (1825). It there appears so clearly how those disciples who do not themselves think become a magnifying mirror of the errors of every thinker. Once having determined his doctrine of the categories, Kant was always cautious when expounding it, but his disciples on the contrary were quite bold, and thus exposed its falseness.

      According to what has been said, the object of the categories is for Kant, not indeed the thing in itself, but yet most closely akin to it. It is the object in itself; it is an object that requires no subject; it is a particular thing, and yet not in space and time, because not perceptible; it is an object of thought, and yet not an abstract conception. Accordingly Kant really makes a triple division: (1.) the idea; (2.) the object of the idea; (3.) the thing in itself. The first belongs to the sensibility, which in its case, as in that of sensation, includes the pure forms of perception, space and time. The second belongs to the understanding, which thinks it through its twelve categories. The third lies beyond the possibility of all knowledge. (In support of this, cf. Critique of Pure Reason, first edition, p. 108 and 109.) The distinction of the idea from the object of the idea is however unfounded; this had already been proved by Berkeley, and it appears from my whole exposition in the first book, especially chap. i. of the supplements; nay, even from Kant's own completely idealistic point of view in the first edition. But if we should not wish to count the object of the idea as belonging to the idea and identify it with the idea, it would be necessary to attribute it to the thing in itself: this ultimately depends on the sense which is attached to the word object. This, however, always remains certain, that, when we think clearly, nothing more can be found than idea and thing in itself. The illicit introduction of that hybrid, the object of the idea, is the source of Kant's errors; yet when it is taken away, the doctrine of the categories as conceptions a priori also falls to the ground; for they bring nothing to the perception, and are not supposed to hold good of the thing in itself, but by means of them we only think those “objects of the ideas,” and thereby change ideas into experience. For every empirical perception is already experience; but every perception which proceeds from sensation is empirical: this sensation is related by the understanding, by means of its sole function (knowledge a priori of the law of causality), to its cause, which just on this account presents itself in space and time (forms of pure perception) as object of experience, material object, enduring in space through all time, yet as such always remains idea, as do space and time themselves. If we desire to go beyond this idea, then we arrive at the question as to the thing in itself, the answer to which is the theme of my whole work, as of all metaphysics in general. Kant's error here explained is connected with his mistake, which we condemned before, that he gives no theory of the origin of empirical perception, but, without saying more, treats it as given, identifying it with the mere sensation, to which he only adds the forms of intuition or perception, space and time, comprehending both under the name sensibility. But from these materials no objective idea arises: this absolutely demands the relation of the idea to its cause, thus the application of the law of causality, and thus understanding; for without this the sensation still remains always subjective, and does not take the form of an object in space, even if space is given with it. But according to Kant, the understanding must not be assigned to perception; it is supposed merely to think, so as to remain within the transcendental logic. With this again is connected another mistake of Kant's: that he left it to me to adduce the only valid proof of the a priori nature of the law of causality which he rightly recognised, the proof from the possibility of objective empirical perception itself, and instead of it gives a palpably false one, as I have already shown in my essay on the principle of sufficient reason, § 23. From the above it is clear that Kant's “object of the idea” (2) is made up of what he has stolen partly from the idea (1), and partly from the thing in itself (3). If, in reality, experience were only brought about by the understanding applying its twelve different functions in order to think through as many conceptions a priori, the objects which were previously merely perceived, then every real thing would necessarily as such have a number of determinations, which, as given a priori, absolutely could not be thought away, just like space and time, but would belong quite essentially to the existence of the thing, and yet could not be deduced from the properties of space and time. But only one such determination is to be found – that of causality. Upon this rests materiality, for the essence of matter consists in action, and it is through and through causality (cf. Bk. II. ch. iv.) But it is materiality alone that distinguishes the real thing from the picture of the imagination, which is then only idea. For matter, as permanent, gives to the thing permanence through all time, in respect of its matter, while the forms change in conformity with causality. Everything else in the thing consists either of determinations of space or of time, or of its empirical properties, which are all referable to its activity, and are thus fuller determinations of causality. But causality enters already as a condition into the empirical perception, and this is accordingly a thing of the understanding, which makes even perception possible, and yet apart from the law of causality contributes nothing to experience and its possibility. What fills the old ontologies is, with the exception of what is given here, nothing more than relations of things to each other, or to our reflection, and a farrago of nonsense.

      The language in which the doctrine of the categories is expressed affords an evidence of its baselessness. What a difference in this respect between the Transcendental Æsthetic and the Transcendental Analytic! In the former, what clearness, definiteness, certainty, firm conviction which is freely expressed and infallibly communicates itself! All is full of light, no dark lurking-places are left: Kant knows what he wants and knows that he is right. In the latter, on the other hand, all is obscure, confused, indefinite, wavering, uncertain, the language anxious, full of excuses and appeals to what is coming, or indeed of suppression. Moreover, the whole second and third sections of the Deduction of the Pure Conceptions of the Understanding are completely changed in the second edition, because they did not satisfy Kant himself, and they have become quite different from the first edition, though not clearer. We actually see Kant in conflict with the truth in order to carry out his hypothesis which he has once fixed upon. In the Transcendental Æsthetic all his propositions are really proved from undeniable facts of consciousness, in the Transcendental Analytic, on the contrary, we find, if we consider it closely, mere assertions that thus it is and must be. Here, then, as everywhere, the language bears the stamp of the thought from which it has proceeded, for style is the physiognomy of the mind. We have still to remark, that whenever Kant wishes to give an example for the purpose of fuller explanation, he almost always takes for this end the category of causality, and then what he has said turns out correct; for the law of causality is indeed the real form of the understanding, but it is also its only form, and the remaining eleven categories are merely blind windows. The deduction of the categories is simpler and less involved in the first edition than in the second. He labours to explain how, according to the perception given by sensibility, the understanding produces experience by means of thinking the categories. In doing so, the words recognition, reproduction, association, apprehension, transcendental unity of apperception, are repeated to weariness, and yet no distinctness is attained. It is well worth noticing, however, that in this explanation he does not once touch upon what must nevertheless first occur to every one – the relation of the sensation to its external cause. If he did not intend this relation to hold good, he ought to have expressly denied it; but neither does he do this. Thus in this way he evades the point, and all the Kantians have in like manner evaded it. The secret motive of this is, that he reserves the causal nexus, under the name “ground of the phenomenon,” for his false deduction of the thing in itself; and also that perception would become intellectual through the relation to the cause, which he dare not admit. Besides this, he seems to have been afraid that if the causal nexus were allowed to hold good between sensation СКАЧАТЬ
