δδ. The fourth antinomy rests on what follows: On the one hand totality completes itself in freedom as a first beginning of action, or in an absolutely necessary Being, as the cause of the world, so that the process is interrupted: but there is opposed to that freedom the necessity of a process according to conditions of causes and effects, and to the necessity of a Being is opposed the consideration that everything is contingent. The absolute necessity of the conditioned world is therefore on the one hand maintained thus: “To the world belongs an absolutely necessary Being.” The opposite to this is, “There exists no absolutely necessary Being, either as part of the world or outside of the world.”[349]
One of these opposites is just as necessary as the other, and it is superfluous to carry this further here. The necessity of these contradictions is the interesting fact which Kant (Kritik der reinen Vernunft, p. 324) has brought to consciousness; in ordinary metaphysics, however, it is imagined that one of these contradictions must hold good, and the other be disproved. The most important point involved in this assertion of Kant’s is, however, unintentional on his part. For he indeed solves these antinomies (Kritik der reinen Vernunft, pp. 385, 386), but only in the particular sense of transcendental idealism, which does not doubt or deny the existence of external things (supra, p. 442), but “allows that things are perceived in space and time” (which is the case, whether it allows it or not): for transcendental idealism, however, “space and time in themselves are not things at all,” and therefore “do not exist apart from our mind;” i.e. all these determinations of a beginning in time, and so on, do not really belong to things, to the implicitude of the phenomenal world, which has independent existence outside of our subjective thought. If such determinations belonged to the world, to God, to free agents, there would be an objective contradiction; but this contradiction is not found as absolute, it pertains only to us. Or, in other words, this transcendental idealism lets the contradiction remain, only it is not Being in itself that is thus contradictory, for the contradiction has its source in our thought alone. Thus the same antinomy remains in our mind; and as it was formerly God who had to take upon Himself all contradictions, so now it is self-consciousness. But the Kantian philosophy does not go on to grapple with the fact that it is not things that are contradictory, but self-consciousness itself. Experience teaches that the ego does not melt away by reason of these contradictions, but continues to exist; we need not therefore trouble ourselves about its contradictions, for it can bear them. Nevertheless Kant shows here too much tenderness for things: it would be a pity, he thinks, if they contradicted themselves. But that mind, which is far higher, should be a contradiction—that is not a pity at all. The contradiction is therefore by no means solved by Kant; and since mind takes it upon itself, and contradiction is self-destructive, mind is in itself all derangement and disorder. The true solution would be found in the statement that the categories have no truth in themselves, and the Unconditioned of Reason just as little, but that it lies in the unity of both as concrete, and in that alone.
γ. Kant now goes on to the Idea of God; this third idea is the Being of Beings, which the other ideas presupposed. Kant says (Kritik der reinen Vernunft, pp. 441-452), that according to the definition of Wolff, God is the most real of all Beings; the object then comes to be to prove that God is not only Thought, but that He is, that He has reality, Being. This Kant calls the Ideal of Reason, to distinguish it from the Idea, which is only the sum of all possibility. The Ideal is thus the Idea as existent; just as in art we give the name of ideal to the Idea realized in a sensuous manner. Here Kant takes into consideration the proof of the existence of God, as he asks whether reality can be assigned to this Ideal.
The ontological proof proceeds from the absolute Notion, in order from it to argue up to Being. With Anselm, Descartes, and Spinoza the transition to Being is thus made; and all of them assume in so doing the unity of Being and thought. But Kant says (Kritik der reinen Vernunft, pp. 458-466): To this Ideal of Reason just as little reality can be assigned: there is no transition from the Notion to Being. “Being is not a real predicate,” like any other, “a Notion of something which might be added to the Notion of a thing. A hundred real dollars do not contain in the very least more than a hundred possible dollars,” they are the same content, i.e. the same Notion; they are also a hundred exactly. The one is the Notion, or rather the conception, the other is the object; Being is no new determination of the Notion, otherwise my Notion of a hundred real dollars would contain something different from a hundred real dollars. But “the object, as real, is not contained in my Notion alone; or to my Notion the real hundred dollars are synthetically added.” Being cannot therefore be derived from the Notion, because it is not contained therein, but must be added to it. “We must go out of the Notion in order to arrive at existence. With regard to objects of pure thought, there are no means of coming to know of their existence, because it had to be known a priori; but our consciousness of all existence belongs entirely to experience.” That is to say, Kant does not attain to the comprehension of that very synthesis of Notion and Being, or in other words, he does not comprehend existence, i.e. he does not attain to the establishment of it as Notion; existence remains for him something absolutely different from a Notion. The content is no doubt the same for him in what exists and in the Notion: but since Being is not involved in the Notion, the attempt to derive the one from the other is unavailing.
Of course the determination of Being is not found as positive and ready-made in the Notion; the Notion is something different from reality and objectivity. If we therefore abide by the Notion, we abide by Being as something different from the Notion, and adhere to the separation of the two; we then have conception, and not Being at all. That a hundred possible dollars are something different from a hundred actual ones is a reflection of a very popular nature, so much so that no proposition has been so well received as the assertion that no transition can be made from the Notion to Being; for though I imagine to myself a hundred dollars, I do not possess them for all that. But in a like popular fashion it might be said that one must leave off imagining, for that is mere conception: i.e. what is merely imaginary is untrue, the hundred imaginary dollars are and remain imaginary. Therefore to believe in them is a proof of an unsound understanding, and is of no manner of use; and he is a foolish fellow who indulges in such fancies and wishes. One possesses a hundred dollars, when they are real only; if a man has therefore so great a desire to possess a hundred dollars, he must put his hand to work in order to obtain them: i.e. he must not come to a standstill at the imagination of them, but pass out beyond it. This subjective side is not the ultimate or the absolute; the true is that which is not merely subjective. If I possess a hundred dollars, I have them actually, and at the same time I form a conception of them to myself. But according to Kant’s representation we come to a deadlock at the difference; dualism is ultimate, and each side has independent validity as an absolute. Against this false idea of what is to be absolute and ultimate, the healthy human understanding is directed; every ordinary consciousness rises above it, every action aims at setting aside a subjective conception and making it into something objective. There is no man so foolish as that philosophy; when a man feels hungry, he does not call up the imagination of food, but sets about satisfying his hunger. All activity is a conception which does not yet exist, but whose subjectivity is abrogated. Moreover the imaginary hundred dollars become real, and the real ones imaginary: this is a frequent experience, this is their fate; it depends on circumstances entirely outward whether a hundred dollars become my property or not. Of course the mere conception is of no good, if I obstinately hold by it: for I can imagine what I will, but that does not make it exist. The only important point is what I conceive to myself, and then whether I think or comprehend the subjective and Being; by means of this each passes into the other. Thought, the Notion, of necessity implies that the Notion does not remain subjective; this subjective is on the contrary abrogated and reveals itself as objective. Now that unity is expressly affirmed by Descartes solely in reference to the Notion of God, for it is just that which is God; he speaks of no hundred dollars, as these are not an existence which has a Notion in itself. That opposition does away with itself absolutely and entirely, i.e. the finite passes away; it holds good only in the philosophy of finitude. If, therefore, there is not a Notion of existence formed, we have in it a notionless, sensuous object of perception; and what is notionless is certainly not a Notion,—therefore sensation, handling, are not Notions. Such existence has of course no Absolute, no real essence: or such existence has no truth, it is only a vanishing moment. This useless thrashing of the empty grainless straw of the common logic is termed philosophizing: it is like Issachar the strong ass, which could not be made to move from the spot where it was (Gen. xlix. 14). People of this kind say: We are good for nothing, and because we are good for nothing, we are good for nothing, and wish to be good for nothing. But it is a very false idea of Christian humility and modesty to desire through one’s abjectness to attain to excellence; this confession of one’s own nothingness is really inward pride and great self-conceit. But for the honour of true humility we must not remain in our misery, but raise ourselves above it by laying hold of the Divine.
The fact to which Kant clings most strongly (Kritik der reinen Vernunft, p. 467) is this, that Being cannot be extracted from the Notion. The result of this is the proposition that to have the thought of the Infinite is certainly Reason; but that from the Idea of Reason is separated determination in general, and especially the determination which is known as Being. The Ideas of Reason cannot be proved from experience, or obtain from it their verification: if they are defined by means of categories, contradictions arise. If the Idea in general is to be defined as existent only, it is nothing more or less than the Notion; and the Being of the existent is still distinguished from it. This result, however, so highly important with reference to knowledge of the understanding, Kant does not, with reference to Reason, carry further than to say that Reason has on its own account nothing but formal unity for the methodical systematization of the knowledge of the understanding. Abstract thinking is adhered to; it is said that the understanding can only bring about order in things; but order is nothing in and for itself, it is only subjective. There therefore remains nothing for Reason except the form of its pure identity with itself, and this extends no further than to the arranging of the manifold laws and relations of the understanding, the classes, kinds and species which the understanding discovers.[350] I, as Reason or conception, and the things external to me, are both absolutely different from one another; and that, according to Kant, is the ultimate standpoint. The animal does not stop at this standpoint, but practically brings about unity. This is the critique of theoretical Reason which Kant gives, and in which he states the a priori and determinate character of Reason in itself, without bringing it to the determinateness of individuality.[351]
Mention should still be made of the positive philosophy or metaphysics, which Kant sets a priori above objective existence, the content of the object of experience, nature; we have here his natural philosophy, which is a demonstration of the universal conceptions of Nature. But this is on the one hand very scanty and restricted in content, containing as it does sundry general qualities and conceptions of matter and motion, and with regard to the scientific side or the a priori, as Kant calls it, it is likewise altogether unsatisfactory. For Kant assumes all such conceptions as that matter has motion and also a power of attraction and repulsion,[352] instead of demonstrating their necessity. The “Principles of Natural Philosophy” have nevertheless been of great service, inasmuch as at the commencement of a philosophy of nature, attention was called to the fact that physical science employs thought-determinations without further investigation; and these determinations constitute the real foundations of its objects. Density, for instance, is looked on by physical science as a variable quantity, as a mere quantum in space: instead of this Kant asserted it to be a certain degree of occupation of space, i.e. energy, intensity of action. He demands accordingly (Metaphysische Anfangsgründe der Naturwissenschaft, pp. 65-68) a construction of matter from powers and activities, not from atoms; and Schelling still holds to this without getting further. Kant’s work is an attempt to think, i.e. to demonstrate the determinations of thought, whose product consists of such conceptions as matter; he has attempted to determine the fundamental Notions and principles of this science, and has given the first impulse to a so-called dynamic theory of Nature.
“Religion within pure Reason” is also a demonstration of dogmas as aspects of Reason, just as in Nature. Thus in the positive dogmas of religion, which the Aufklärung (the clearing-up)—or the Ausklärung (the clearing-out)—made short work of, Kant called to remembrance Ideas of Reason, asking what rational and, first of all, what moral meaning lies in that which men call dogmas of religion, e.g. original sin.[353] He is much more reasonable than the Ausklärung, which thinks it beneath its dignity to speak of such matters. These are the principal points in respect to the theoretical part of Kant’s philosophy.
2. The second subject of review in Kant’s philosophy is the practical sphere, the nature and principle of the will; this subject is dealt with in the Critique of Practical Reason, in which Kant accepted Rousseau’s conclusion that the will is absolutely free. Kant’s idea of theoretic Reason is that when Reason relates itself to an object, this object must be given to it; but when the object is given by Reason to itself, it has no truth; and Reason in knowledge of this kind does not arrive at independence. As practical, on the contrary, Reason is independent in itself; as a moral Being man is free, raised above all natural law and above all phenomena. As the theoretic Reason had in itself categories, a priori distinctions, so practical Reason has in turn the moral law in general, the further determinations of which are constituted by the notions of duty and right, lawful and unlawful; and here Reason disdains all the given material which was necessary to it on the theoretic side. The will determines itself within itself; all that is right and moral rests on freedom; in this man has his absolute self-consciousness.[354] On this side self-consciousness finds essential reality in itself, as theoretical Reason found it in an “other”; and in the first place, indeed, the ego in its individuality is immediate reality, universality, objectivity; in the second place subjectivity strives after reality, but not after sensuous reality such as we had before, for here Reason holds itself to be the real. Here we have the Notion which is sensible of its own deficiency; this theoretic Reason could not be, as in it the Notion had to remain the Notion. Thus we have the standpoint of absoluteness revealed, since there is an infinite disclosed within the human breast. The satisfying part in Kant’s philosophy is that the truth is at least set within the heart; and hence I acknowledge that, and that alone, which is in conformity with my determined nature.
a. Kant divides will into lower and higher faculties of desire; this expression is not inapt. The lower faculties of desire are impulses, inclinations, etc.; the higher faculty is the will as such, which has not external, individual aims, but universal. To the question what the principle of will that should determine man in his actions is, all sorts of answers have been given; for instance, self-love, benevolence, happiness, etc. Such material principles of action, Kant now says, are all reducible to impulses, to happiness; but the rational in itself is purely formal, and consists in the maxim that what is to hold good as law, must be capable of being thought of as a law of universal application, without destroying itself. All morality of action now rests upon the conviction that the act is done with consciousness of the law, for the sake of the law and out of respect for the law and for itself, without any regard to what makes for happiness. As a moral Being man has the moral law in himself, the principle of which is freedom and autonomy of the will; for the will is absolute spontaneity. Determinations which are taken from the inclinations are heterogeneous principles as regards the will; or the will is heteronomy if it takes such determinations as its end and aim; for in that case it takes its determinations from something else than itself. But the essence of the will is to determine itself from itself; for practical Reason gives itself laws. But the empirical will is heteronomous, for it is determined by desires; and they belong to our nature, not to the realm of freedom.[355]
