It is a highly important point in the Kantian philosophy that what self-consciousness esteems reality, law, and implicit Being, is brought back within itself. While a man is striving after this aim and that, according as he judges the world or history in one way or the other, what is he to take as his ultimate aim? For the will, however, there is no other aim than that derived from itself, the aim of its freedom. It is a great advance when the principle is established that freedom is the last hinge on which man turns, a highest possible pinnacle, which allows nothing further to be imposed upon it; thus man bows to no authority, and acknowledges no obligations, where his freedom is not respected. Great popularity has from one point of view been won for Kantian philosophy by the teaching that man finds in himself an absolutely firm, unwavering centre-point; but with this last principle it has come to a standstill. While the highest pinnacle of the theoretic Reason is abstract identity, because it can furnish only a canon, a rule for abstract classifications,[356] practical Reason, as law-giving, is immediately regarded as concrete; the law which it gives to itself is the moral law. But even if it is stated that it is concrete in itself, there is the further consideration that this freedom is at first only the negative of everything else; no bond, nothing external, lays me under an obligation. It is to this extent indeterminate; it is the identity of the will with itself, its at-homeness with itself. But what is the content of this law? Here we at once come back to the lack of content. For the sole form of this principle is nothing more or less than agreement with itself, universality; the formal principle of legislation in this internal solitude comes to no determination, or this is abstraction only. The universal, the non-contradiction of self, is without content, something which comes to be reality in the practical sphere just as little as in the theoretical. The universal moral law Kant therefore expresses thus (and the setting up of such a universal form was at all times the demand of the abstract understanding): “Act from maxims” (the law is also to be my particular law), “which are capable of becoming universal laws.”[357]
Thus for the determination of duty (for the question which meets us is, what is duty for the free will) Kant has contributed nothing but the form of identity, which is the law of abstract Understanding. To defend one’s fatherland, to promote the happiness of another, is a duty, not because of the content, but because it is duty; as with the Stoics, what was thought was true for the very reason that, and in so far as it was thought (Vol. II., pp. 254, 260, 263). The content as such is indeed not what holds good universally in the moral law, because it contradicts itself. For benevolence, for instance, enjoins: “Give your possessions to the poor,” but if all give away what they have, beneficence is done away with (Vol. I., pp. 417, 418). Even with abstract identity, however, we do not get a step further, for every content which is put into this form is by being so put freed from self-contradiction. But nothing would be lost if it were not put into this form at all. With regard to property, for instance, the law of my actions is this: Property ought to be respected, for the opposite of this cannot be universal law. That is correct, but it is quite a formal determination: If property is, then it is. Property is here presupposed, but this determination may also in the same way be omitted, and then there is no contradiction involved in theft: If there is no such thing as property, then it is not respected. This is the defect in the principle of Kant and Fichte, that it is really formal; chill duty is the final undigested lump left within the stomach, the revelation given to Reason.
The first postulate in practical Reason is thus free, independent will which determines itself, but this concrete is still abstract. The second and third are forms which remind us that the will is concrete in a higher sense.
b. The second point is the connection of the Notion of the will with the particular will of the individual; the concrete is here the fact that my particular will and the universal will are identical, or that I am a moral human being. The unity, that man should be moral, is postulated; but beyond the “should” and this talk of morality, no advance is made. It is not said what is moral; and no thought is given to a system of the self-realizing spirit. For really, as theoretic Reason stands opposed to the objective of the senses, so practical Reason stands opposed to the practical sensuousness, to impulses and inclinations. Perfected morality must remain a Beyond; for morality presupposes the difference of the particular and universal will. It is a struggle, the determination of the sensuous by the universal; the struggle can only take place when the sensuous will is not yet in conformity with the universal. The result is, therefore, that the aim of the moral will is to be attained in infinite progress only; on this Kant founds (Kritik der prakt. Vernunft, pp. 219-223) the postulate of the immortality of the soul, as the endless progress of the subject in his morality, because morality itself is incomplete, and must advance into infinitude. The particular will is certainly something other than the universal will; but it is not ultimate or really permanent.
c. The third point is the highest concrete, the Notion of the freedom of all men, or the natural world has to be in harmony with the Notion of freedom. That is the postulate of the existence of God, whom Reason, however, does not recognize. Will has the whole world, the whole of the sensuous, in opposition to it, and yet Reason insists on the unity of Nature or the moral law, as the Idea of the Good, which is the ultimate end of the world. Since, however, it is formal, and therefore has no content on its own account, it stands opposed to the impulses and inclinations of a subjective and an external independent Nature. Kant reconciles the contradiction of the two (Kritik der prakt. Vernunft, pp. 198-200) in the thought of the highest Good, in which Nature is conformed to rational will, and happiness to virtue;—a harmony which does not enter into the question at all, although practical reality consists therein. For happiness is only one’s own sensuous consciousness, or the actuality of a particular individual, not universal reality in itself. The unification spoken of itself therefore remains only a Beyond, a thought, which is not actually in existence, but only ought to be. Kant (Kritik der prakt. Vernunft, pp. 205-209) thus agrees entirely with the talk which alleges that in this world it often fares ill with the good, and well with the wicked, and so on; and he postulates further the existence of God as the Being, the causality, through whom this harmony comes to pass, on behalf both of the sanctity of the moral law, and of the rational end to be attained in Nature, but only in infinite progress; which postulate, like that of the immortality of the soul, allows the contradiction to remain as it is all the time, and expresses only in the abstract that the reconciliation ought to come about. The postulate itself is always there, because the Good is a Beyond with respect to Nature; the law of necessity and the law of liberty are different from one another, and placed in this dualism. Nature would remain Nature no longer, if it were to become conformed to the Notion of the Good; and thus there remains an utter opposition between the two sides, because they cannot unite. It is likewise necessary to establish the unity of the two; but this is never actual, for their separation is exactly what is presupposed. Kant employs popular language thus: evil ought to be overcome, but yet must not have been overcome. God is to him, therefore, only a faith, an opinion, which is only subjectively, and not absolutely true.[358] This result is also of a very popular character.
These postulates express nothing but the synthesis, devoid of thought, of the different moments which contradict each other on every hand; they are therefore a “nest”[359] of contradictions. For instance, the immortality of the soul is postulated on account of imperfect morality, i.e. because it is infected with sensuousness. But the sensuous is implied in moral self-consciousness; the end, perfection, is what really destroys morality as such. Similarly the other aim, the harmony of the sensuous and the rational, to an equal extent abrogates morality; for that consists in this very opposition of Reason to the sensuous. The actuality of the God who produces harmony is of such a character that it does not enter into consciousness at all; it is accepted by consciousness for the sake of harmony, just as children make some kind of scarecrow, and then agree with each other to pretend to be afraid of it. The ground on which God is accepted—that by the conception of a holy law-giver the moral law may acquire additional reverence—contradicts the fact that morality really consists in reverence for the law simply for its own sake.[360] In Practical Reason self-consciousness esteems itself to be implicit Being, as contrasted with theoretic Reason, which assigns implicitude to objective existence, but the one, we see, attains just as little as the other to unity and actuality in itself. It is hard for man to believe that Reason actually exists: but there is nothing real except Reason; it is the absolute power. The vanity of man aspires to have an ideal before him, in order to be able to find fault with everything alike. We possess all wisdom, it is within us, but is not forthcoming. That is the ultimate standpoint; it is a high standpoint, no doubt, but in it the truth is never reached. The absolute Good remains “what ought to be,” or without objectivity; and there it has to remain.
3. There is still left for us to consider the third side in Kant’s philosophy, the Critique of the Faculty of Judgment, in which the demand for the concrete comes in, the demand that the Idea of unity spoken of before should be established not as a Beyond, but as present; and this side is of special importance. Kant says that the understanding no doubt regulates in the theoretic sphere and produces categories; but these remain mere general determinations, beyond which lies the particular (the other element which belongs to every item of knowledge). The two are distinguished from one another for the understanding; for its distinctions remain in universality. In the practical sphere Reason is certainly the implicit, but its free independence, its law-giving freedom in higher form, is opposed to Nature in its freedom or to Nature’s own laws. “In the theoretic sphere Reason can draw conclusions from given laws through syllogisms, only by means of the understanding, and these conclusions never get beyond Nature; it is only in the practical sphere that Reason itself gives laws. Understanding and” (practical) “Reason have two different regulative systems on one and the same ground of experience, without the one being detrimental to the other. For if the Notion of Nature has but little influence on the giving of laws by the Notion of Freedom, just as little does the latter interfere with the legislation of Nature. The possibility of the existence side by side of the two regulative systems and of the powers belonging to them was proved in the Critique of pure Reason.” (!?) “Now if a unity is not constituted by these two different spheres, which certainly do not put a limit on each other in their regulative action, but do so incessantly in their operations in the sensuous world” (i.e. where they encounter each other), “the reason is this, that the Notion of Nature represents its objects in perception, not as things in themselves, but as mere phenomena, while the Notion of Freedom, on the other hand, represents in its object a thing in itself, no doubt, but not in perception. Consequently neither of them can attain to a theoretic knowledge of its object (and even of the thinking subject) as a thing-in-itself, which last would be the supersensuous, an unlimited and inaccessible realm for our whole faculty of knowledge. Now truly there is fixed a gulf over which the eye cannot reach, between the realm of the Notion of Nature, as the sensuous, and the realm of the Notion of Freedom, as the supersensuous, so that it is not possible to pass from the one to the other, since it is just as if there were two different worlds, the first of which could have no influence on the second. Nevertheless the latter is conceived as having an influence on the former, or, in other words, freedom is conceived as having for its mission the realization in the sensuous world of the end indicated by the laws of freedom. Consequently Nature must be so conceived that, while in form it realizes its own laws, there may yet be a possibility of ends being realized in it according to the laws of freedom. Therefore there must surely be some ground for the unity of the supersensuous which lies at the foundation of Nature with that which the Notion of Freedom practically contains, the Notion of which ground of unity, although it attains neither theoretically nor practically to a knowledge of the same, and consequently has no peculiar province, yet makes possible the transition from the mode of thought in accordance with the principles of the one, to the mode of thought in accordance with the principles of the other. Between Understanding and Reason there now comes the Faculty of Judgment, as between the powers of knowledge and desire there come pleasure and its opposite; in this faculty must therefore lie the transition from the province of the Notions of Nature to the province of the Notion of Freedom.”[361]
Adaptation to ends has its place here, i.e. a particular reality, which is determined only through the universal, the end. The understanding is the ground of this unity of the manifold; the sensuous is therefore here determined by means of the supersensuous. This idea of a universal which implicitly contains the particular is according to Kant the precise object of the faculty of judgment, which he divides as follows:—“If the universal (the rule, principle, law) is given, the faculty of judgment which subsumes the particular under that universal, is determinative,”—the immediate faculty of judgment. But here there is also a particular which is not determined by species. “If, however, only the particular is given, for which the faculty of judgment has to find the universal, it is reflective.” The reflective judgment has as its principle the unity of particularity and the abstract universal of the understanding, the idea of a legal necessity which is at the same time free, or of a freedom which is directly one with its content. “This principle can be no other but the fact that since universal laws of Nature have their foundation in our understanding, which prescribes them to nature, although only according to their general conception, the particular, empirical laws, in so far as they are undetermined by universal laws, must be viewed as containing that unity which they would contain if they had been given by some intelligence—other, it may be, than our own—with express reference to our cognitive faculties, in order to render possible a system of experience according to particular natural laws. It is not as if such an intelligence must be assumed (for it is only the reflective faculty of judgment to which this idea serves as principle): this faculty gives a law only to itself, not to Nature in addition. Now the conception of an object (if it at the same time contains the ground of the reality of this object), the end, and the harmony of a thing with that quality of things which is only possible in conformity with ends, are termed the adaptation to purpose of the form; therefore the principle of the faculty of judgment in respect to the form of the things of Nature under empirical laws in general is the adaptability to purpose of Nature in its multiplicity. That is to say, Nature is represented by this Notion as if an intelligence contained the ground of the unity in multiplicity of Nature’s empirical laws.”[362]
Aristotle already regarded Nature as in itself showing this adaptation to end, and as having in itself νοῦς, intelligence, the Universal, so that in undivided unity one element is moment of another (v. Vol. II. pp. 156-162). Purpose is the Notion, and immanent; not external form and abstraction as distinguished from a fundamental material, but penetrating, so that all that is particular is determined by this universal itself. According to Kant this is Understanding: no doubt the laws of the Understanding, which it implicitly has in knowledge, leave the objective still undetermined, but because this manifold itself must have a connection in itself, which is yet contingent for human intelligence, “the faculty of judgment must assume as a principle for its own use that what is contingent for us contains a unity, which for us indeed is not knowable, but yet thinkable, in the connection of the manifold with an implicitly possible experience.”[363] This principle hereby at once falls back again into the subjectivity of a thought, and is only a maxim of our reflection, by which nothing is to be expressed regarding the objective nature of the object,[364] because Being-in-itself is once for all fixed outside of self-consciousness, and the Understanding is conceived only in the form of the self-conscious, not in its becoming another.
Now this principle of the reflective faculty of judgment is in itself a two-fold adaptation to end, the formal and the material; the faculty of judgment is thus either æsthetic or teleological: of these the former has to do with subjective, the latter with objective, logical adaptation to end. There are thus two objects of the faculty of judgment—the beautiful in works of art and the natural products of organic life—which make known to us the unity of the Notion of Nature and the Notion of Freedom.[365] The consideration of these works involves the fact, that we see a unity of the Understanding and the particular. But as this consideration is only a subjective manner of representing such products, and does not contain the truth of the same, such things are regarded only according to this unity, and they are not in themselves of this nature; what they are in themselves lies beyond.
