Chapter XXIV: Section THREE: Recent German Philosophy (1)

In the philosophy of Kant, Fichte, and Schelling, the revolution to which in Germany mind has in these latter days advanced, was formally thought out and expressed; the sequence of these philosophies shows the course which thought has taken. In this great epoch of the world’s history, whose inmost essence is laid hold of in the philosophy of history, two nations only have played a part, the German and the French, and this in spite of their absolute opposition, or rather because they are so opposite. The other nations have taken no real inward part in the same, although politically they have indeed so done, both through their governments and their people. In Germany this principle has burst forth as thought, spirit, Notion; in France, in the form of actuality. In Germany, what there is of actuality comes to us as a force of external circumstances, and as a reaction against the same. The task of modern German philosophy is, however, summed up in taking as its object the unity of thought and Being, which is the fundamental idea of philosophy generally, and comprehending it, that is, in laying hold of the inmost significance of necessity, the Notion (_supra_, p. 360). The philosophy of Kant sets forth, in the first place, the formal aspect of the task, but it has the abstract absoluteness of reason in self-consciousness as its sole result, and, in one respect, it carried with it a certain character of shallowness and want of vigour, in which an attitude of criticism and negativity is retained, and which, as far as any positive element is concerned, adheres to the facts of consciousness and to mere conjecture, while it renounces thought and returns to feeling. On the other hand, however, there sprang from this the philosophy of Fichte, which speculatively grasps the essence of self-consciousness as concrete egoism, but which does not reach beyond this subjective form pertaining to the absolute. From it again comes the philosophy of Schelling, which subsequently rejects Fichte’s teaching and sets forth the Idea of the Absolute, the truth in and for itself.

A. JACOBI.

In connection with Kant we must here begin by speaking of Jacobi, whose philosophy is contemporaneous with that of Kant; in both of these the advance beyond the preceding period is very evident. The result in the two cases is much the same, although both the starting point and the method of progression are somewhat different. In Jacobi’s case the stimulus was given mainly by French philosophy, with which he was very conversant, and also by German metaphysics, while Kant began rather from the English side, that is, from the scepticism of Hume. Jacobi, in that negative attitude which he preserved as well as Kant, kept before him the objective aspect of the method of knowledge, and specially considered it, for he declared knowledge to be in its content incapable of recognizing the Absolute: the truth must be concrete, present, but not finite. Kant does not consider the content, but took the view of knowledge being subjective; and for this reason he declared it to be incapable of recognizing absolute existence. To Kant knowledge is thus a knowledge of phenomena only, not because the categories are merely limited and finite, but because they are subjective. To Jacobi, on the other hand, the chief point is that the categories are not merely subjective, but that they themselves are conditioned. This is an essential difference between the two points of view, even if they both arrive at the same result.

Friedrich Heinrich Jacobi, born at Düsseldorf in 1743, held office first in the Duchy of Berg, and then in Bavaria. He studied in Geneva and Paris, associating in the former place with Bonnet and in the latter with Diderot. Jacobi was a man of the highest character and culture. He was long occupied with State affairs, and in Düsseldorf he held a public office which was connected with the administration of the finance department in the State. At the time of the French Revolution he was obliged to retire. As a Bavarian official he went to Munich, there became President of the Academy of Sciences in 1804, which office he, however, resigned in 1812; for in the Napoleonic period Protestants were decried as demagogues. He lived at Munich till the end of his life, and died at the same place on the 10th of March, 1819.[315]

In the year 1785, Jacobi published Letters on Spinoza, which were written in 1783, on the occasion of the dispute with Mendelssohn above-mentioned (p. 406); for in none of his writings did Jacobi develop his philosophy systematically, he set it forth in letters only. When Mendelssohn wished to write a life of Lessing, Jacobi sent to ask him if he knew that “Lessing was a Spinozist” (Jacobi’s Werke, Vol. IV. Sec. 1, pp. 39, 40). Mendelssohn was displeased at this, and it was the occasion of the correspondence. In the course of the dispute it was made evident that those who held themselves to be professed philosophers and possessed of a monopoly of Lessing’s friendship, such as Nicolai, Mendelssohn, &c., knew nothing about Spinozism; not only was there manifested in them the superficial character of their philosophic insight, but ignorance as well; with Mendelssohn, for instance, this was shown respecting even the outward history of the Spinozistic philosophy, and much more regarding the inward (Jacobi’s Werke, Vol. IV. Sec. 1, p. 91). That Jacobi asserted Lessing to be a Spinozist, and gave a high place to the French—this serious statement came to these good men as a thunderbolt from the blue. They—the self-satisfied, self-possessed, superior persons—were quite surprised that he also made pretensions to knowledge, and of such a “dead dog” as Spinoza (_ibidem_, p. 68). Explanations followed upon this, in which Jacobi further developed his philosophic views.

Mendelssohn is directly opposed to Jacobi, for Mendelssohn took his stand on cognition, placed true existence immediately in thought and conception, and maintained: “What I cannot think as true does not trouble me as doubt. A question which I do not understand, I cannot answer, it is for me as good as no question at all.”[316] He continued to argue on these same lines. His proof of the existence of God thus carries with it this necessity of thought, viz. that actuality must plainly be in thought, and a thinker must be presupposed, or the possibility of the actual is in the thinker. “What no thinking Being conceives as possible is not possible, and what is thought by no thinking creature as actual cannot be actual in fact. If we take away from anything whatsoever the conception formed by a thinking Being that that thing is possible or actual, the thing itself is done away with.” The Notion of the thing is thus to man the essence of the same. “No finite Being can think the actuality of a thing in its perfection as actual, and still less can he perceive the possibility and actuality of all present things. There must thus be a thinking Being or an understanding which in the most perfect way thinks the content of all possibilities as possible, and the content of all actualities as actual; _i.e._ there must be an infinite understanding, and this is God.”[317] Here on the one hand we see a unity of thought and Being, on the other the absolute unity as infinite understanding—the former is the self-consciousness which is apprehended as finite merely. Actuality, Being, has its possibility in thought, or its possibility is thought; it is not a process from possibility to actuality, for the possibility remains at home in the actuality.

Jacobi maintains against these demands of thought—and this in one view is the chief thought in his philosophy—that every method of their demonstration leads to fatalism, atheism, and Spinozism,[318] and presents God as derived and founded upon something else; for comprehending Him signifies demonstrating His dependence. Jacobi thus asserts that mediate knowledge consists in giving a cause of something which has in its turn a finite effect, and so on; so that a knowledge such as this can all through relate to the finite only.

Jacobi further states upon this subject, in the first place, that “Reason”—later on when he distinguished reason and understanding (of which more hereafter[319]), he altered it to understanding[320]—“can never bring to light more than the conditions of what is conditioned, natural laws and mechanism. We comprehend a thing when we can deduce it from its proximate causes,” and not from the remoter causes; the most remote and quite universal cause is always God. “Or” we know the thing if we “perceive its immediate conditions as they come in due succession. Thus, for instance, we comprehend a circle when we can clearly represent to ourselves the mechanism of its origination or its physical conditions; we know the syllogistic formulæ when we have actually come to know the laws to which the human understanding is subject in judgment and conclusion, its physical nature and its mechanism. For this reason we have no conceptions of qualities as such, but only intuitions. Even of our present existence we have a feeling only, but no conceptions. Genuine conceptions we have merely of figure, number, position, movement and the forms of thought; qualities are known and understood, if they are traced back to these and objectively annulled.” This is undoubtedly really finite knowledge, which is to give the determinate conditions of anything determinate, to demonstrate it as resulting from another cause, in such a way that each condition is again conditioned and finite. Jacobi continues: “The business of reason is really progressive union and connection, and its speculative business is union and connection in accordance with the known laws of necessity, _i.e._ of identity. Everything that reason can bring forth by means of analysis, combination, judgment, conclusion, and re-conception, consists in nothing but things of nature” (_i.e._ finite things), “and reason itself, as a limited existence, belongs to these things. But the whole of nature, the sum of all conditioned existence, cannot reveal more to the investigating understanding than what is contained in it, namely, manifold existence, changes, a succession of forms” (the conditioned), “and not an actual beginning” (of the world), “nor a real principle of any objective existence.”[321]

But Jacobi in the second place here accepts reason in a wider sense and says: “If we understand by reason the principle of knowledge generally, it is the mind from which the whole living nature of man is constituted; through it man arises; he is a form which it has adopted.” With this Jacobi’s view of the attempt to know the unconditioned is connected. “I take the whole human being, and find that his consciousness is composed of two original conceptions, the conceptions of the conditioned and the unconditioned. Both are inseparably bound up with one another, and yet in such a way that the conception of the conditioned presupposes the conception of the unconditioned, and can be given in this alone. We are just as certain of its existence as we are of our own conditioned existence, or even more so. Since our conditioned existence rests on an infinitude of mediations, there is opened up to our investigation a vast field which, for the sake of our preservation even, we are forced to work upon.” It would, however, be quite another thing to wish to know the unconditioned apart from this practical end. However Jacobi here remarks, “To try to discover the conditions of the unconditioned, to find a possibility for absolute necessity, and to construct this last in order to be able to comprehend it, is what we undertake when we endeavour to make nature an existence comprehensible to us, _i.e._ a merely natural existence, and to bring the mechanism of the principle of mechanism into the light of day. For if everything which can be said to arise and be present in a way comprehensible to us, must arise and be present in a conditioned way, we remain, so long as we continue to comprehend, in a chain of conditioned conditions. Where this chain breaks off, we cease to comprehend, and there the connection which we call nature likewise ceases. The conception of the possibility of the outward existence of nature would thus be the conception of an absolute beginning or origin of nature; it would be the conception of the unconditioned itself in so far as it is a conditioning of nature not naturally connected, _i.e._ a conditioning of nature unconnected and unconditioned for us. Now should a conception of what is thus unconditioned and unconnected, and consequently supernatural, be possible, the unconditioned must cease to be unconditioned, it must itself receive conditions; and absolute necessity must commence to be possibility in order that it may allow itself to be constructed.”[322] This is contradictory.

Jacobi then passes on from this point to the second of his main propositions, “The unconditioned is called the supernatural. Now since everything which lies outside the connection of what is conditioned, of what is naturally mediated, also lies outside the sphere of our clear and certain knowledge, and cannot be understood through conceptions, the supernatural cannot be accepted in any other way by us than that in which it is given to us—namely as a fact. It is! This supernatural, this essence of all essence, all tongues join in proclaiming to be God.”[323] God as the universal, the true, is here taken in the sense of a spiritual generally, in the sense of power, wisdom, &c. That God is, however, is to Jacobi not absolutely true; for to knowledge pertains His objective absolute existence, but He cannot be said to be known. It is thus merely a fact of my consciousness that God exists independently apart from my consciousness; this, however, is itself maintained through my consciousness; the subjective attitude of thought is thus to Jacobi the element of most importance. The consciousness of God, which is in our consciousness, is, however, of such a nature that along with the thought of God we have immediately associated the fact that He is. The existence of the supernatural and supersensuous, to which the thought of man regarding the natural and finite passes on, is just as certain to Jacobi as he is himself. This certainty is identical with his self-consciousness; as certainly as I am, so certainly is God (Jacobi’s Werke, Vol. III. p. 35). Since he thus passes back into self-consciousness, the unconditioned is only for us in an immediate way; this immediate knowledge Jacobi calls Faith, inward revelation (Werke, Vol. II. pp. 3, 4); to this appeal can be made in man. God, the absolute, the unconditioned, cannot, according to Jacobi, be proved. For proof, comprehension, means to discover conditions for something, to derive it from conditions; but a derived absolute, God, &c., would thus not be absolute at all, would not be unconditioned, would not be God (Jacobi’s Werke, Vol. III. p. 7). This immediate knowledge of God is then the point which is maintained in the philosophy of Jacobi. The faith of Kant and of Jacobi are, however, different. To Kant it is a postulate of reason, it is the demand for the solution of the contradiction between the world and goodness; to Jacobi it is represented on its own account as immediate knowledge.

Everything which has been written upon God since Jacobi’s time, by philosophers such as Fries and by theologians, rests on this conception of immediate intellectual knowledge, and men even call this revelation, though in another sense than the revelation of theology. Revelation as immediate knowledge is in ourselves, while the Church holds revelation to be something imparted from without.[324] In the theological sense, faith is faith in something which is given to us through teaching. It is a sort of deception when faith and revelation are spoken of and represented as if faith and revelation in the theological sense were here in question; for the sense in which they are used, and which may be termed philosophic, is quite a different one, however pious an air may be assumed in using the terms. This is Jacobi’s standpoint, and whatever is by philosophers and theologians said against it, this teaching is eagerly accepted and disseminated. And nowhere is there anything to be found but reflections originating from Jacobi, whereby immediate knowledge is opposed to philosophic knowledge and to reason; and people speak of reason, philosophy, &c., as a blind man speaks of colours. It is, indeed, allowed that a man cannot make shoes unless he is a shoemaker, even although he have the measure and foot, and also the hands. But when Philosophy is concerned, immediate knowledge signifies that every man as he walks and stands is a philosopher, that he can dogmatize as he chooses, and that he is completely acquainted with Philosophy.

By reason, however, mediate knowledge merely is on the one hand understood, and on the other the intellectual perception which speaks of facts (_supra_, pp. 413-415). In this respect it is true that reason is the knowledge and revelation of absolute truth, since the understanding is the revelation of the finite (Jacobi’s Werke, Vol. II. pp. 8-14, 101). “We maintained that two different powers of perception in man have to be accepted: a power of perception through visible and tangible and consequently corporeal organs of perception, and another kind of power, viz. through an invisible organ which in no way represents itself to the outward senses, and whose existence is made known to us through feeling alone. This organ, a spiritual eye for spiritual objects, has been called by men—generally speaking—reason. He whom the pure feelings of the beautiful and good, of admiration and love, of respect and awe, do not convince that in and with these feelings he perceives something to be present which is independent of them, and which is unattainable by the outward senses or by an understanding directed upon their perceptions alone—such an one cannot be argued with” (Jacobi’s Werke, Vol. II. pp. 74, 76). But by faith Jacobi likewise understands all that has immediacy of Being for me: “Through faith we know that we have a body, we become aware of other actual things, and that indeed with the same certainty with which we are aware of ourselves. We obtain all conceptions through the qualities which we receive and accept, and there is no other way of attaining real knowledge; for reason, when it begets objects, begets phantoms of the brain. Thus we have a revelation of nature.”[325] Hence the expression faith, which had a deep significance in religion, is made use of for different contents of every kind; this in our own time is the point of view most commonly adopted.

Jacobi here brings faith into opposition with thought. Let us compare the two, and discover whether they are separated by so great a chasm as those who thus oppose them think. On the one hand absolute existence is to faith immediate; believing consciousness feels itself penetrated by this as by its essence: that existence is its life, believing consciousness asserts itself to be in direct unity with it. Thought thinks the absolute existence; such existence is to it absolute thought, absolute understanding, pure thought; but that signifies that it is likewise immediate itself. On the other hand to faith the immediacy of absolute existence has also the significance of a Being: it _is_, and is another than ‘I.’ And the same is true of the thinker; to him it is absolute Being, actual in itself, and different from self-consciousness or thought as finite understanding, to use the common term. Now what is the reason that faith and thought do not understand one another, and each recognize itself in the other? In the first place faith has no consciousness of being a thought, inasmuch as it asserts absolute consciousness to be identical with it as self-consciousness, and has direct inward knowledge of the same. But it expresses this simple unity; in its consciousness it is only immediacy so to speak in the signification of Being, a unity of its unconscious substance. In the second place Being-for-self is contained in thought; to this faith opposes the immediacy of Being. Thought, on the contrary, has the immediate as absolute potentiality, as absolutely a thing of thought: and the immediacy belonging to this thing of thought is without the determination of Being, of life. On the heights of this abstraction the two stand opposed to each other, as the _Aufklärung_ which asserts absolute existence to be a Beyond of self-consciousness, and as the materialism which makes it so to speak present matter (_supra_, pp. 382, 383). In the one case it is in faith and thought as positive existence or thought, and in the other it is the negative of self-consciousness, which is thus either only determined as negative, as a Beyond, or likewise as existent for self-consciousness. Hence faith and thought are both of them knowledge. We call universal knowledge thought, particular knowledge we call sensuous perception; and we term the introduction of external determinations understanding. The universal element in man is thought, but to it likewise appertains religious feeling for instance; the animal does not possess it, for it has no human feeling; and in so far as this feeling is religious, it is the feeling of a thinker, and what determines this feeling is not the determination of natural desire, &c., but a universal determination. Thus God, even though He is only felt and believed in, is yet the universal taken quite abstractly—even in His personality He is the absolutely universal personality.

As thought and faith are thus one, the same is true of the antithesis between mediated and immediate knowledge. We must, it is true, keep before our eyes the fact that what is revealed in immediate knowledge is the universal. But abstract immediate knowledge is natural, sensuous knowledge; the immediate man in his natural condition, in his desires, does not know this universal. Children, the Esquimaux, &c., know nothing of God; or what the natural man knows of Him is not a real knowledge of Him. Thus the intuitive knowledge of the Egyptians told them that God was an ox or a cat, and the Indians still possess similar sorts of knowledge. On the other hand when man has come so far as to know God as merely an object of the mind, _i.e._ as spiritual, it is easy to perceive that this knowledge which is asserted to be immediate is really a result mediated through instruction, through a long continued culture. It is only by means of being elevated above nature that man arrives at a consciousness of what is higher, and at a knowledge of the universal; there indeed his knowledge is immediate, but he has only arrived at this through mediation. I think, and thus I know the universal immediately, but this very thought is just process in itself, movement and life. All life is process within itself, is mediated, and this is all the more true of spiritual life; for it is the passing from one to the other, that is, from the merely natural and sensuous to the spiritual. It thus indicates a deficiency in the most simple reflection not to know that the universal is not in immediate knowledge, but is a result of the culture, the education, and the self-revelation of the human race. If immediate knowledge is to be allowed, everyone will be responsible merely to himself: this man knows this, another that, and consequently everything is justified and approved, however contrary to right and religion. This opposition between immediacy and mediacy is thus a very barren and quite empty determination; it is a platitude of the extremest type to consider anything like this to be a true opposition; it proceeds from a most wooden understanding, which thinks that an immediacy can be something on its own account, without a mediation within itself. If Philosophy were to result in this it would be a poor affair; these determinations are merely forms, none of which has intrinsic truth. The form into which Philosophy has in Jacobi’s case finally fallen, which is that immediacy is grasped as absolute, manifests a lack of all critical faculty, of all logic. The Kantian philosophy is critical philosophy, but from it the fact has been omitted that we cannot constitute the infinite with finite categories—and immediacy is such an one. When we regard this opposition more closely all knowledge may be termed immediate, but all immediate knowledge is likewise mediated in itself. This we know within our consciousness, and we may see it in the most general phenomena. I know, for example, of America immediately, and yet this knowledge is very much mediated. If I stand in America and see its soil, I must first of all have journeyed to it, Columbus must first have discovered it, ships must have been built, &c.; all these discoveries and inventions pertain to it. That which we now know immediately is consequently a result of infinitely many mediations. Likewise when I see a right-angled triangle I know that the squares of the two sides are equal to the square of the hypotenuse: I know this immediately, and yet I have merely learned it and am convinced of it through the mediation of proof. Immediate knowledge is thus everywhere mediated, and Philosophy does nothing but bring this to consciousness—demonstrating the mediation which in point of fact is already present there, _e.g._ in religion, &c.

The philosophy of Jacobi, inasmuch as it says: “Thought cannot proceed further than to the feeling of God,” has been accepted _utiliter_; it was more easily arrived at than in the case of Kant. Knowledge, however, is something very different from what Jacobi calls such; against finite knowledge his arguments are quite correct. Immediate knowledge is not knowledge, comprehension, for that implies that the content is determined in itself, _i.e._ is grasped as concrete. But in immediate knowledge it is the case that the only fact known of God is that He exists. For should there be determinations respecting God, they must, according to Jacobi, be grasped as a finite, and the knowledge of them would again merely be a progression from finite to finite. There thus remains only the indeterminate conception of God, an “Above me,” an indeterminate Beyond. This gives accordingly the same result as does the _Aufklärung_, viz. that the highest reality is ultimate: we find the same in French philosophy and in Kant—only here we still have the opinion that this emptiness is the highest philosophy possible. But if each standpoint has an aspect wherein it is justified, there always rests in the proposition that the human mind knows God immediately, the important consideration that we have here a recognition of the freedom of the human spirit: in it we have the source of the knowledge of God, and all externality of authority is thus abrogated in this principle. The principle is hereby gained, but only the principle of freedom of spirit; and the greatness of our time rests in the fact that freedom, the peculiar possession of mind whereby it is at home with itself in itself, is recognized, and that mind has this consciousness within itself. This however is merely abstract, for the next step is that the principle of freedom is again purified and comes to its true objectivity, so that not everything which strikes me or springs up within me must, because it is manifested in me, hold good as true. It is only through thought, which casts off the particular and accidental, that the principle receives this objectivity which is independent of mere subjectivity and in and for itself—though in such a way that the freedom of mind still remains respected. One’s own spirit must bear witness to spirit that God is Spirit; the content must be true. But this does not give authenticity to itself by its being revealed with certainty to me. This is the standpoint, and we have thus seen its deficiency and the greatness of the principle which is involved in it.

B. KANT.

The philosophy of Kant, which we have now more particularly to consider, made its appearance at the same time as the above. While Descartes asserted certainty to be the unity of thought and Being, we now have the consciousness of thought in its subjectivity, _i.e._ in the first place, as determinateness in contrast with objectivity, and then as finitude and progression in finite determinations. Abstract thought as personal conviction is that which is maintained as certain; its contents are experience, but the methods adopted by experience are once more formal thought and argument. Kant turns back to the standpoint of Socrates; we see in him the freedom of the subject as we saw it with the Stoics, but the task in respect of content is now placed on a higher level. An endless aiming at the concrete is required for thought, a filling up in accordance with the rule which completion prescribes, which signifies that the content is itself the Idea as the unity of the Notion and reality. With Jacobi thought, demonstration, does not in the first place reach beyond the finite and conditioned, and in the second place, even when God is likewise the metaphysical object, the demonstration is really the making Him conditioned and finite; in the third place the unconditioned, what is then immediately certain, only exists in faith, a subjectively fixed point of view but an unknowable one, that is to say an undetermined, indeterminable, and consequently an unfruitful one. The standpoint of the philosophy of Kant, on the contrary, is in the first place to be found in the fact that thought has through its reasoning got so far as to grasp itself not as contingent but rather as in itself the absolute ultimate. In the finite, in connection with the finite, an absolute standpoint is raised which acts as a connecting bond; it binds together the finite and leads up to the infinite. Thought grasped itself as all in all, as absolute in judgment; for it nothing external is authoritative, since all authority can receive validity only through thought. This thought, determining itself within itself and concrete, is, however, in the second place, grasped as subjective, and this aspect of subjectivity is the form which from Jacobi’s point of view is predominant; the fact that thought is concrete Jacobi has on the other hand for the most part set aside. Both standpoints remain philosophies of subjectivity; since thought is subjective, the capacity of knowing the absolute is denied to it. To Kant God cannot on the one hand be found in experience; He can neither be found in outward experience—as Lalande discovered when he swept the whole heavens and found no God—nor can He be discovered within; though no doubt mystics and enthusiasts can experience many things in themselves, and amongst these God, _i.e._ the Infinite. On the other hand Kant argues to prove the existence of God, who is to him an hypothesis necessary for the explanation of things, a postulate of practical reason. But in this connection another French astronomer made the following reply to the Emperor Napoleon: “_Je n’ai pas eu besoin de cette hypothèse._” According to this the truth underlying the Kantian philosophy is the recognition of freedom. Even Rousseau represented the absolute to be found in freedom; Kant has the same principle, but taken rather from the theoretic side. The French regard it from the side of will, which is represented in their proverb: “_Il a la tête près du bonnet._” France possesses the sense of actuality, of promptitude; because in that country conception passes more immediately into action, men have there applied themselves more practically to the affairs of actuality. But however much freedom may be in itself concrete, it was as undeveloped and in its abstraction that it was there applied to actuality; and to make abstractions hold good in actuality means to destroy actuality. The fanaticism which characterized the freedom which was put into the hands of the people was frightful. In Germany the same principle asserted the rights of consciousness on its own account, but it has been worked out in a merely theoretic way. We have commotions of every kind within us and around us, but through them all the German head quietly keeps its nightcap on and silently carries on its operations beneath it.

Immanuel Kant was born at Königsberg in 1724, and there studied theology to begin with; in the year 1755 he entered upon his work as an academic teacher; in 1770 he became professor of logic, and in 1804 he died at Königsberg on the 12th of February, having almost attained his eightieth year (Tennemann’s Grundriss der Geschichte der Philosophie by Wendt, § 380, pp. 465, 466), without ever having left his native town.

While to Wolff thought as thought was merely positive self-identity and grasped itself as such, we saw the negative self-moving thought, the absolute Notion, appear in all its power in France; and in the _Aufklärung_ it likewise made its way to Germany in such a manner that all existence, all action, was called upon to serve a useful purpose, _i.e._ the implicit was done away with and everything had to be for another; and that for which everything had to be is man, self-consciousness, taken, however, as signifying all men generally. The consciousness of this action in abstract form is the Kantian philosophy. It is thus the self-thinking absolute Notion that passes into itself which we see making its appearance in Germany through this philosophy, in such a way that all reality falls within self-consciousness; it is the idealism which vindicates all moments of the implicit to self-consciousness, but which at first itself remains subject to a contradiction, inasmuch as it still separates this implicit from itself. In other words the Kantian philosophy no doubt leads reality back to self-consciousness, but it can supply no reality to this essence of self-consciousness, or to this pure self-consciousness, nor can it demonstrate Being in the same. It apprehends simple thought as having difference in itself, but does not yet apprehend that all reality rests on this difference; it does not know how to obtain mastery over the individuality of self-consciousness, and although it describes reason very well, it does this in an unthinking empiric way which again robs it of the truth it has. Theoretically the Kantian philosophy is the “Illumination” or _Aufklärung_ reduced to method; it states that nothing true can be known, but only the phenomenal; it leads knowledge into consciousness and self-consciousness, but from this standpoint maintains it to be a subjective and finite knowledge. Thus although it deals with the infinite Idea, expressing its formal categories and arriving at its concrete claims, it yet again denies this to be the truth, making it a simple subjective, because it has once for all accepted finite knowledge as the fixed and ultimate standpoint. This philosophy made an end of the metaphysic of the understanding as an objective dogmatism, but in fact it merely transformed it into a subjective dogmatism, _i.e._ into a consciousness in which these same finite determinations of the understanding persist, and the question of what is true in and for itself has been abandoned. Its study is made difficult by its diffuseness and prolixity, and by the peculiar terminology found in it. Nevertheless this diffuseness has one advantage, that inasmuch as the same thing is often repeated, the main points are kept before us, and these cannot easily be lost from view.

We shall endeavour to trace the lines which Kant pursued. The philosophy of Kant has in the first place a direct relation to that of Hume as stated above (p. 370). That is to say, the significance of the Kantian philosophy, generally expressed, is from the very beginning to allow that determinations such as those of universality and necessity are not to be met with in perception, and this Hume has already shown in relation to Locke. But while Hume attacks the universality and necessity of the categories generally, and Jacobi their finitude, Kant merely argues against their objectivity in so far as they are present in external things themselves, while maintaining them to be objective in the sense of holding good as universal and necessary, as they do, for instance, in mathematics and natural science.[326] The fact that we crave for universality and necessity as that which first constitutes the objective, Kant thus undoubtedly allows. But if universality and necessity do not exist in external things, the question arises “Where are they to be found?” To this Kant, as against Hume, maintains that they must be _a priori_, _i.e._ that they must rest on reason itself, and on thought as self-conscious reason; their source is the subject, “I” in my self-consciousness.[327] This, simply expressed, is the main point in the Kantian philosophy.

In the second place the philosophy of Kant is likewise called a critical philosophy because its aim, says Kant, is first of all to supply a criticism of our faculties of knowledge; for before obtaining knowledge we must inquire into the faculties of knowledge. To the healthy human understanding that is plausible, and to it this has been a great discovery. Knowledge is thereby represented as an instrument, as a method and means whereby we endeavour to possess ourselves of the truth. Thus before men can make their way to the truth itself they must know the nature and function of their instrument. They must see whether it is capable of supplying what is demanded of it—of seizing upon the object; they must know what the alterations it makes in the object are, in order that these alterations may not be mixed up with the determinations of the object itself.[328] This would appear as though men could set forth upon the search for truth with spears and staves. And a further claim is made when it is said that we must know the faculty of knowledge before we can know. For to investigate the faculties of knowledge means to know them; but how we are to know without knowing, how we are to apprehend the truth before the truth, it is impossible to say. It is the old story of the σχολαστικός who would not go into the water till he could swim. Thus since the investigation of the faculties of knowledge is itself knowing, it cannot in Kant attain to what it aims at because it is that already—it cannot come to itself because it is already with itself; the same thing happens as happened with the Jews, the Spirit passes through the midst of them and they know it not. At the same time the step taken by Kant is a great and important one—that is, the fact that he has made knowledge the subject of his consideration.

On the one hand this critique of knowledge applies to the empirical knowledge of Locke, which asserts itself to be grounded on experience, and, on the other hand, it also deals with what claims to be on the whole a more metaphysical kind of philosophy—the Wolffian and German—which had also taken up the line of proceeding on the more empiric method which has been depicted. But this last has at the same time kept itself separate from the merely empiric method, inasmuch as its main efforts have been directed towards making such categories of thought as those of potentiality, actuality, God, &c., have as their foundation categories of the understanding, and then reasoning from them. The Kantian philosophy is in the first instance directed against both. Kant takes away the objective significance of the determinations of the Wolffian metaphysics, and shows how they must be ascribed to subjective thought alone. At the same time Jacobi likewise declared himself against this metaphysic, but since he started more especially from the standpoint of the French and Germans, his point of view was different: he asserts that our finite thought can set forth finite determinations alone, and thus can only consider God and Spirit in accordance with finite relationships. On the practical side there reigned at that time the so-called happiness theory, since man’s inherent Notion and the way to realize this Notion was apprehended in morality as a satisfaction of his desires. As against this Kant has very rightly shown that it involves a heteronomy and not an autonomy of reason—a determination through nature and consequently an absence of freedom. But because the rational principle of Kant was formal, and his successors could not make any further progress with reason, and yet morality had to receive a content, Fries and others must still be called Hedonists though they avoid giving themselves the name.

In the third place, as regards the relation of the categories to the material which is given through experience, there is according to Kant already inherent in the subjective determinations of thought, _e.g._ in those of cause and effect, the capacity of themselves to bind together the differences which are present in that material. Kant considers thought as in great measure a synthetic activity, and hence he represents the main question of Philosophy to be this, “How are synthetic judgments _a priori_ possible?”[329] Judgment signifies the combination of thought-determinations as subject and predicate. Synthetic judgments _a priori_ are nothing else than a connection of opposites through themselves, or the absolute Notion, _i.e._ the relations of different determinations such as those of cause and effect, given not through experience but through thought. Space and time likewise form the connecting element; they are thus _a priori_, _i.e._ in self-consciousness. Since Kant shows that thought has synthetic judgments _a priori_ which are not derived from perception, he shows that thought is so to speak concrete in itself. The idea which is present here is a great one, but, on the other hand, quite an ordinary signification is given it, for it is worked out from points of view which are inherently rude and empirical, and a scientific form is the last thing that can be claimed for it. In the presentation of it there is a lack of philosophical abstraction, and it is expressed in the most commonplace way; to say nothing more of the barbarous terminology, Kant remains restricted and confined by his psychological point of view and empirical methods.

To mention one example only of his barbarous expressions, Kant calls his philosophy (Kritik der reinen Vernunft, p. 19) a Transcendental philosophy, _i.e._ a system of principles of pure reason which demonstrate the universal and necessary elements in the self-conscious understanding, without occupying themselves with objects or inquiring what universality and necessity are; this last would be transcendent. Transcendent and transcendental have accordingly to be clearly distinguished. Transcendent mathematics signifies the mathematics in which the determination of infinitude is made use of in a pre-eminent degree: in this sphere of mathematics we say, for instance, that the circle consists of an infinitude of straight lines; the periphery is represented as straight, and since the curve is represented as straight this passes beyond the geometric category and is consequently transcendent. Kant, on the contrary, defines the transcendental philosophy as not a philosophy which by means of categories passes beyond its own sphere, but one which points out in subjective thought, in consciousness, the sources of what may become transcendent. Thought would thus be transcendent if the categories of universality, of cause and effect, were predicated of the object, for in this way men would from the subjective element ‘transcend’ into another sphere. We are not justified in so doing as regards the result nor even to begin with, since we merely contemplate thought within thought itself. Thus we do not desire to consider the categories in their objective sense, but in so far as thought is the source of such synthetic relationships; the necessary and universal thus here receive the significance of resting in our faculties of knowledge. But from this faculty of knowledge Kant still separates the implicit, the thing-in-itself, so that the universality and necessity are all the time a subjective conditionment of knowledge merely, and reason with its universality and necessity does not attain to a knowledge of the truth.[330] For it requires perception and experience, a material empirically given in order, as subjectivity, to attain to knowledge. As Kant says, these form its “constituent parts”; one part it has in itself, but the other is empirically given.[331] When reason desires to be independent, to exist in itself and to derive truth from itself, it becomes transcendent; it transcends experience because it lacks the other constituent, and then creates mere hallucinations of the brain. It is hence not constitutive in knowledge but only regulative; it is the unity and rule for the sensuous manifold. But this unity on its own account is the unconditioned, which, transcending experience, merely arrives at contradictions. In the practical sphere alone is reason constitutive. The critique of reason is consequently not the knowing of objects, but of knowledge and its principles, its range and limitations, so that it does not become transcendent.[332] This is an extremely general account of what we shall now consider in its separate details.

In dealing with this matter Kant adopts the plan of first considering theoretic reason, the knowledge which relates to outward objects. In the second place he investigates the will as self-actualization; and, in the third place, the faculty of judgment, the special consideration of the unity of the universal and individual; how far he gets in this matter we shall likewise see. But the critique of the faculty of knowledge is the matter of main importance.

1. In the first place, as to the theoretic philosophy, Kant in the Critique of Pure Reason sets to work in a psychological manner, _i.e._ historically, inasmuch as he describes the main stages in theoretic consciousness. The first faculty is sensuousness generally, the second understanding, the third reason. All this he simply narrates; he accepts it quite empirically, without developing it from the Notion or proceeding by necessity.

a. The _a priori_ fact of sensuous existence, the forms of sensuous existence, constitute the beginning of this transcendentalism. Kant calls the judgment of the same the transcendental æsthetic. Nowadays æsthetic signifies the knowledge of the beautiful. But here the doctrine of intuition or perception is taken from the point of view of its universality, _i.e._ from what in it pertains to the subject as such. Perception, says Kant, is the knowledge of an object given to us through the senses; sensuousness, however, is the capacity of being affected by conceptions as external. Now, according to Kant, in perception there are to be found all manner of contents, and in dealing with this he first of all distinguishes feeling as external, such as redness, colour, hardness, &c., and then as internal, such as justice, wrath, love, fear, pleasurable and religious feelings, &c. He says content such as this forms the one constituent and pertains to feeling; all this is subjective and merely subjective. In this sensuous element there is, however, a universal sensuous element likewise contained, which as such does not belong to feeling in so far as it is immediately determined; in such a content this ‘other’ consists in the categories of space and time, which of themselves are void and empty. The filling in is performed by the content, by colour, softness, hardness, &c., as regards space; while as regards time, the same content, so soon as it is something transient, or again some other content, and in particular inward feelings are what causes the determination. Space and time are consequently pure, _i.e._ abstract perceptions in which we place outside of us the content of individual sensations, either in time as succeeding one another, or in space as separate from one another. Here we thus meet with the division between subjectivity and objectivity, for if we isolate the ‘alongside of’ and ‘after’ we have space and time. It is the act of _a priori_ sensuousness to project the content; the forms of intuition or perception constitute this pure perception.[333] Now everything indeed is termed perception, even thought and consciousness; God, who certainly pertains to thought alone, is said to be comprehended by perception or intuition, the so-called immediate consciousness.

Kant further remarks in this regard, (1) “Space is no empirical Notion which has been derived from outward experiences.” But the Notion is never really anything empiric: it is in barbarous forms like this that Kant, however, always expresses himself: “For in order that I may relate my sensations to something outside of me, I must presuppose space.” Of time Kant speaks in similar terms: “In order that something outside of me may be represented in separate space or time, the conception of space and time must come first, or it cannot be derived from experience, for experience first becomes possible through this antecedent conception.” That is to say, time and space which may appear as objective, since their particular filling in certainly belongs to subjective feeling, are not empirical; for consciousness has time and space first of all in itself. (2) “Space is a necessary conception which lies at the basis of all external perceptions. Space and time are conceptions _a priori_, because we cannot represent things without space and time. Time is a necessary basis for all phenomena.” As _a priori_, space and time are universal and necessary, that is to say we find this to be the case; but it does not follow that they must be previously present as conceptions. They are fundamental indeed, but they are likewise an external universal. Kant however places the matter somewhat in this fashion: there are things-in-themselves outside, but devoid of time and space; consciousness now comes, and it has time and space beforehand present in it as the possibility of experience, just as in order to eat it has mouth and teeth, &c., as conditions necessary for eating. The things which are eaten have not the mouth and teeth, and as eating is brought to bear on things, so space and time are also brought to bear on them; just as things are placed in the mouth and between the teeth, so is it with space and time. (3) “Space and time are not general Notions of the relations of things, but pure intuitive perceptions. For we can only represent to ourselves one space; there are not different component parts of space.” The same is the case with time. The abstract conception tree, for example, is in its actuality a number of individual and separate trees, but spaces are not such particulars, nor are they parts; for one immediate continuity remains, and hence a simple unity. Ordinary perception has always something individual before it; space or time are always however one only, and therefore _a priori_. It might however be replied to Kant: The nature of space and time undoubtedly involves their being an abstract universal; but there is in like manner only one blue. (4) “Each Notion or conception certainly comprises an infinite number of conceptions under itself, but not within itself; nevertheless this last is the case in space and time, and they are therefore intuitive perceptions and not Notions or conceptions.”[334] Space and time, then, are certainly not thought-determinations, if no thoughts are there present, but a Notion, so soon as we have a Notion of them.

From the transcendental point of view it is likewise maintained that this conception of space and time contains synthetic propositions _a priori_, connected with the consciousness of its necessity. Examples of these synthetic propositions are sought in statements such as that of space having three dimensions, or in the definition of a straight line, that it is the shortest distance between two points, and likewise in the statement that 5 + 7 = 12.[335] All these propositions are however very analytic. Kant nevertheless in the first place holds that such propositions do not take their rise from experience, or, as we might better express it, are not an individual contingent perception; this is very true, the perception is universal and necessary. In the second place he states that we acquire them from pure sensuous perception, and not through the understanding or Notion. But Kant does not grasp the two together, and yet this comprehension of them is involved in such propositions being immediately certain even in ordinary perception. When Kant then expresses himself (Kritik der reinen Vernunft, p. 49) to the effect that we have many sensations which constitute “the real matter,” with which we externally and inwardly “occupy our minds,” and that the mind has in itself in space and time “formal conditions of the mode in which we place them” (those manifold feelings) “in our mind,” the question of how mind arrives at having just these special forms now forces itself upon us. But what the nature of time and space is, it does not occur to the Kantian philosophy to inquire. To it what space and time are in themselves does not signify ‘What is their Notion,’ but ‘Are they external things or something in the mind?’
