However, Kant finally comes forward with a pretended principle of the reason answering to his demand, yet only with this one, from which others afterwards follow as corollaries. It is the principle which Chr. Wolf set up and explained in his “Cosmologia,” sect. i. c. 2, § 93, and in his “Ontologia,” § 178. As now above, under the title of the Amphiboly, mere Leibnitzian philosophemes were taken for natural and necessary aberrations of the reason, and were criticised as such, so here precisely the same thing happens with the philosophemes of Wolf. Kant still presents this principle of the reason in an obscure light, through indistinctness, indefiniteness, and breaking of it up (p. 307; V. 361, and 322; V. 379). Clearly expressed, however, it is as follows: “If the conditioned is given, the totality of its conditions must also be given, [pg 091] and therefore also the unconditioned, through which alone that totality becomes complete.” We become most vividly aware of the apparent truth of this proposition if we imagine the conditions and the conditioned as the links of a suspended chain, the upper end of which, however, is not visible, so that it might extend ad infinitum; since, however, the chain does not fall, but hangs, there must be above one link which is the first, and in some way is fixed. Or, more briefly: the reason desires to have a point of attachment for the causal chain which reaches back to infinity; it would be convenient for it. But we will examine the proposition, not in figures, but in itself. Synthetic it certainly is; for, analytically, nothing more follows from the conception of the conditioned than that of the condition. It has not, however, a priori truth, nor even a posteriori, but it surreptitiously obtains its appearance of truth in a very subtle way, which I must now point out. Immediately, and a priori, we have the knowledge which the principle of sufficient reason in its four forms expresses. From this immediate knowledge all abstract expressions of the principle of sufficient reason are derived, and they are thus indirect; still more, however, is this the case with inferences or corollaries from them. I have already explained above how abstract knowledge often unites a variety of intuitive cognitions in one form or one concept in such a way that they can no longer be distinguished; therefore abstract knowledge stands to intuitive knowledge as the shadow to the real objects, the great multiplicity of which it presents through one outline comprehending them all. Now the pretended principle of the reason makes use of this shadow. In order to deduce from the principle of sufficient reason the unconditioned, which directly contradicts it, it prudently abandons the immediate concrete knowledge of the content of the principle of sufficient reason in its particular forms, and only makes use of abstract concepts which are derived from it, and have value and significance only through it, in order to smuggle [pg 092] its unconditioned somehow or other into the wide sphere of those concepts. Its procedure becomes most distinct when clothed in dialectical form; for example, thus: “If the conditioned exists, its condition must also be given, and indeed all given, thus completely, thus the totality of its conditions; consequently, if they constitute a series, the whole series, consequently also its first beginning, thus the unconditioned.” Here it is false that the conditions of a conditioned can constitute a series. Rather must the totality of the conditions of everything conditioned be contained in its nearest ground or reason from which it directly proceeds, and which is only thus a sufficient ground or reason. For example, the different determinations of the state which is the cause, all of which must be present together before the effect can take place. But the series, for example, the chain of causes, arises merely from the fact that we regard what immediately before was the condition as now a conditioned; but then at once the whole operation begins again from the beginning, and the principle of sufficient reason appears anew with its claim. But there can never be for a conditioned a properly successive series of conditions, which exist merely as such, and on account of that which is at last conditioned; it is always an alternating series of conditioneds and conditions; as each link is laid aside the chain is broken, and the claim of the principle of sufficient reason entirely satisfied, it arises anew because the condition becomes the conditioned. Thus the principle of sufficient reason always demands only the completeness of the immediate or next condition, never the completeness of a series. But just this conception of the completeness of the condition leaves it undetermined whether this completeness should be simultaneous or successive; and since the latter is chosen, the demand now arises for a complete series of conditions following each other. Only through an arbitrary abstraction is a series of causes and effects regarded as a series of causes alone, which exists merely on account [pg 093] of the last effect, and is therefore demanded as its sufficient reason. From closer and more intelligent consideration, and by rising from the indefinite generality of abstraction to the particular definite reality, it appears, on the contrary, that the demand for a sufficient reason extends only to the completeness of the determinations of the immediate cause, not to the completeness of a series. The demand of the principle of sufficient reason is completely extinguished in each sufficient reason given. It arises, however, immediately anew, because this reason is again regarded as a consequent; but it never demands directly a series of reasons. If, on the other hand, instead of going to the thing itself, we confine ourselves to the abstract concepts, these distinctions vanish. Then a chain of alternating causes and effects, or of alternating logical reasons and consequents, is given out as simply a chain of causes of the last effect, or reasons of the last consequent, and the completeness of the conditions, through which alone a reason becomes sufficient, appears as the completeness of that assumed series of reasons alone, which only exist on account of the last consequent. There then appears the abstract principle of the reason very boldly with its demand for the unconditioned. But, in order to recognise the invalidity of this claim, there is no need of a critique of reason by means of antinomies and their solution, but only of a critique of reason understood in my sense, an examination of the relation of abstract knowledge to direct intuitive knowledge, by means of ascending from the indefinite generality of the former to the fixed definiteness of the latter. From such a critique, then, it here appears that the nature of the reason by no means consists in the demand for an unconditioned; for, whenever it proceeds with full deliberation, it must itself find that an unconditioned is an absurdity. The reason as a faculty of knowledge can always have to do only with objects; but every object for the subject is necessarily and irrevocably subordinated to the principle of sufficient [pg 094] reason, both a parte ante and a parte post. The validity of the principle of sufficient reason is so involved in the form of consciousness that we absolutely cannot imagine anything objective of which no why could further be demanded; thus we cannot imagine an absolute absolute, like a blind wall in front of us. That his convenience should lead this or that person to stop at some point, and assume such an absolute at pleasure, is of no avail against that incontestable certainty a priori, even if he should put on an air of great importance in doing so. In fact, the whole talk about the absolute, almost the sole theme of philosophies since Kant, is nothing but the cosmological proof incognito. This proof, in consequence of the case brought against it by Kant, deprived of all right and declared outlawed, dare no longer show itself in its true form, and therefore appears in all kinds of disguises—now in distinguished form, concealed under intellectual intuition or pure thought; now as a suspicious vagabond, half begging, half demanding what it wants in more unpretending philosophemes. If an absolute must absolutely be had, then I will give one which is far better fitted to meet all the demands which are made on such a thing than these visionary phantoms; it is matter. It has no beginning, and it is imperishable; thus it is really independent, and quod per se est et per se concipitur; from its womb all proceeds, and to it all returns; what more can be desired of an absolute? But to those with whom no critique of reason has succeeded, we should rather say—
“Are not ye like unto women, who ever
Return to the point from which they set out,
Though reason should have been talked by the hour?”
That the return to an unconditioned cause, to a first beginning, by no means lies in the nature of reason, is, moreover, practically proved by the fact that the primitive religions of our race, which even yet have the greatest number of followers upon earth, Brahmanism and [pg 095] Buddhaism, neither know nor admit such assumptions, but carry the series of phenomena conditioning each other into infinity. Upon this point, I refer to the note appended to the criticism of the first antinomy, which occurs further on; and the reader may also see Upham's “Doctrine of Buddhaism” (p. 9), and in general all genuine accounts of the religions of Asia. Judaism and reason ought not to be identified.
Kant, who by no means desires to maintain his pretended principle of reason as objectively valid, but merely as subjectively necessary, deduces it even as such only by means of a shallow sophism, p. 307; V. 364. He says that because we seek to subsume every truth known to us under a more general truth, as far as this process can be carried, this is nothing else than the pursuit of the unconditioned, which we already presuppose. But, in truth, in this endeavour we do nothing more than apply reason, and intentionally make use of it to simplify our knowledge by enabling us to survey it—reason, which is that faculty of abstract, general knowledge that distinguishes the reflective, thinking man, endowed with speech, from the brute, which is the slave of the present. For the use of reason just consists in this, that we know the particular through the universal, the case through the rule, the rule through the more general rule; thus that we seek the most general points of view. Through such survey or general view our knowledge is so facilitated and perfected that from it arises the great difference between the life of the brutes and that of men, and again between the life of educated and that of uneducated men. Now, certainly the series of grounds of knowledge, which exist only in the sphere of the abstract, thus of reason, always finds an end in what is indemonstrable, i.e., in an idea which is not further conditioned according to this form of the principle of sufficient reason, thus in the a priori or a posteriori directly perceptible ground of the first proposition of the train of reasoning. I have already shown in the essay on [pg 096] the principle of sufficient reason, § 50, that here the series of grounds of knowledge really passes over into grounds of becoming or of being. But one can only desire to make this circumstance hold good as a proof of an unconditioned according to the law of causality, or even of the mere demand for such an unconditioned, if one has not yet distinguished the forms of the principle of sufficient reason at all, but, holding to the abstract expression, has confounded them all. Kant, however, seeks to establish that confusion, through a mere play upon words, with Universalitas and Universitas, p. 322; V. 379. Thus it is fundamentally false that our search for higher grounds of knowledge, more general truths, springs from the presupposition of an object unconditioned in its being, or has anything whatever in common with this. Moreover, how should it be essential to the reason to presuppose something which it must know to be an absurdity as soon as it reflects? The source of that conception of the unconditioned is rather to be found only in the indolence of the individual who wishes by means of it to get rid of all further questions, whether his own or of others, though entirely without justification.
Now Kant himself denies objective validity to this pretended principle of reason; he gives it, however, as a necessary subjective assumption, and thus introduces an irremediable split into our knowledge, which he soon allows to appear more clearly. With this purpose he unfolds that principle of reason further, p. 322; V. 379, in accordance with the method of architectonic symmetry of which he is so fond. From the three categories of relation spring three kinds of syllogisms, each of which gives the clue for the discovery of a special unconditioned, of which again there are three: the soul, the world (as an object in itself and absolute totality), and God. Now here we must at once note a great contradiction, of which Kant, however, takes no notice, because it would be very dangerous to the symmetry. Two of these unconditioneds [pg 097] are themselves conditioned by the third, the soul and the world by God, who is the cause of their existence. Thus the two former have by no means the predicate of unconditionedness in common with the latter, though this is really the point here, but only that of inferred being according to the principles of experience, beyond the sphere of the possibility of experience.
Setting this aside, we recognise in the three unconditioneds, to which, according to Kant, reason, following its essential laws, must come, the three principal subjects round which the whole of philosophy under the influence of Christianity, from the Scholastics down to Christian Wolf, has turned. Accessible and familiar as these conceptions have become through all these philosophers, and now also through the philosophers of pure reason, this by no means shows that, without revelation, they would necessarily have proceeded from the development of all reason as a production peculiar to its very nature. In order to prove this it would be necessary to call in the aid of historical criticism, and to examine whether the ancient and non-European nations, especially the peoples of Hindostan and many of the oldest Greek philosophers, really attained to those conceptions, or whether it is only we who, by quite falsely translating the Brahma of the Hindus and the Tien of the Chinese as “God,” good-naturedly attribute such conceptions to them, just as the Greeks recognised their gods everywhere; whether it is not rather the case that theism proper is only to be found in the religion of the Jews, and in the two religions which have proceeded from it, whose followers just on this account comprise the adherents of all other religions on earth under the name of heathen, which, by the way, is a most absurd and crude expression, and ought to be banished at least from the writings of the learned, because it identifies and jumbles together Brahmanists, Buddhists, Egyptians, Greeks, Romans, Germans, Gauls, Iroquois, Patagonians, Caribbeans, Otaheiteans, Australians, and [pg 098] many others. Such an expression is all very well for priests, but in the learned world it must at once be shown the door: it can go to England and take up its abode at Oxford. It is a thoroughly established fact that Buddhism, the religion which numbers more followers than any other on earth, contains absolutely no theism, indeed rejects it. As regards Plato, it is my opinion that he owes to the Jews the theism with which he is periodically seized. On this account Numenius (according to Clem. Alex., Strom., i. c. 22, Euseb. præp. evang., xiii. 12, and Suidas under Numenius) called him the Moses græcisans: Τι γαρ εστι Πλατων, η Μωσης αττικιζων; and he accuses him of having stolen (αποσυλησας) his doctrine of God and the creation from the Mosaical writings. Clemens often repeats that Plato knew and made use of Moses, e.g., Strom., i. 25.—v. c. 14, § 90, &c., &c.; Pædagog., ii. 10, and iii. 11; also in the Cohortatio ad gentes, c. 6, where, after he has bitterly censured and derided the whole of the Greek philosophers in the preceding chapter because they were not Jews, he bestows on Plato nothing but praise, and breaks out into pure exultation that as Plato had learnt his geometry from the Egyptians, his astronomy from the Babylonians, magic from the Thracians, and much also from the Assyrians, so he had learnt his theism from the Jews: Οιδα σου τους διδασκαλους, καν αποκρυπτειν εθελῇς, ... δοξαν την του θεου παρ᾽ αυτων ωφελησει των Εβραιων (Tuos magistros novi, licet eos celare velis, ... illa de Deo sententia suppeditata tibi est ab Hebræis). A pathetic scene of recognition. But I see a remarkable confirmation of the matter in what follows. According to Plutarch (in Mario), and, better, according to Lactantius (i. 3, 19), Plato thanked Nature that he had been born a human being and not a brute, a man and not a woman, a Greek and not a barbarian. Now in Isaac Euchel's “Prayers of the Jews,” from the Hebrew, second edition, 1799, p. 7, there is a morning prayer in which God is thanked and praised [pg 099] that the worshipper was born a Jew and not a heathen, a free man and not a slave, a man and not a woman. Such an historical investigation would have spared Kant an unfortunate necessity in which he now becomes involved, in that he makes these three conceptions spring necessarily from the nature of reason, and yet explains that they are untenable and unverifiable by the reason, and thus makes the reason itself a sophisticator; for he says, p. 339; V. 397: “There are sophistications, not of man, but of pure reason itself, from which even the wisest cannot free himself, and although after much trouble he may be able to avoid error, yet he never can escape from the illusion which unceasingly torments and mocks him.” Therefore these Kantian “Ideas of the Reason” might be compared to the focus in which the converging reflected rays from a concave mirror meet several inches before its surface, in consequence of which, by an inevitable process of the understanding, an object presents itself to us there which is a thing without reality.
But the name “Idea” is very unfortunately chosen for these pretended necessary productions of the pure theoretical reason, and violently appropriated from Plato, who used it to denote the eternal forms which, multiplied through space and time, become partially visible in the innumerable individual fleeting things. Plato's “Ideas” are accordingly throughout perceptible, as indeed the word which he chose so definitely signifies, for it could only be adequately translated by means of perceptible or visible things; and Kant has appropriated it to denote that which lies so far from all possibility of perception that even abstract thought can only half attain to it. The word “Idea,” which Plato first introduced, has, moreover, since then, through two-and-twenty centuries, always retained the significance in which he used it; for not only all ancient philosophers, but also all the Scholastics, and indeed the Church Fathers and the theologians of the Middle Ages, used it only in that Platonic sense, the [pg 100] sense of the Latin word exemplar, as Suarez expressly mentions in his twenty-fifth Disputation, sect. 1. That Englishmen and Frenchmen were later induced by the poverty of their languages to misuse this word is bad enough, but not of importance. Kant's misuse of the word idea, by the substitution of a new significance introduced by means of the slender clue of not being object of experience, which it has in common with Plato's ideas, but also in common with every possible chimera, is thus altogether unjustifiable. Now, since the misuse of a few years is not to be considered against the authority of many centuries, I have always used the word in its old, original, Platonic significance.
