"In so far as the me opposes to itself a not-me, it necessarily supposes limits, and supposes itself in these limits. It divides the totality of the being supposed in general between the me and the not-me; so far supposes itself necessarily as finite."[62]
143. Thus Fichte in a few words destroys the reality of the external world, converting it into a modification or development of the activity of the me. Is it necessary to stop any longer to refute such an absurd doctrine, one, too, founded on no proof? I believe not: especially since I have established on solid principles the demonstration of the existence of an external world, and have explained the origin and character of the facts of consciousness, without having recourse to such extravagant absurdities.[63]
[CHAPTER XIX.]
RELATIONS OF FICHTE'S SYSTEM TO THE DOCTRINES OF KANT.
144. I have already shown[64] how Kant's system leads to Fichte's. When a dangerous principle is established, there is never wanting an author bold enough to deduce its consequences, whatever they may be. The author of the Doctrine of Science, led astray by the doctrines of Kant, establishes the most extravagant pantheism that was ever invented. In concluding his work, he says that he leaves the reader at the point where Kant takes him; he ought rather to have said that he takes the reader at the point where Kant leaves him. The author of the Critic of Pure Reason, by converting space into a purely subjective fact, destroys the reality of extension, and opens the door to those who wish to deduce all nature from the me; and by making time a simple form of the internal sense, he causes the succession of phenomena in time to be considered as mere modifications of the me to the form of which they relate.
145. But it is far from being necessary for us to hunt after deductions; the philosopher himself, in the midst of his obscurity and enigmatical language, does not cease to lay down in the most precise manner this monstrous doctrine. Let us hear how he speaks in his transcendental Logic, where he proposes to explain the relation of the understanding to objects in general, and the possibility of knowing them a priori. "The order and regularity in phenomena, that which we call nature, is consequently our own work; we should not find it there if we had not placed it there by the nature of our mind; for this natural unity must be a necessary unity, that is to say, a certain unity a priori of the connection of the phenomena. But how could we produce a synthetic unity a priori, if there were not in the primitive sources of our mind subjective reasons of this unity a priori, and if these subjective conditions were not at the same time objectively valid, since they are the grounds of the possibility of knowing in general an object in experience?"[65] Who does not see in these words the germ of Fichte's system, which deduces from the me the not-me, that is to say, the world, and gives to nature no other validity than that which it has received from the me?
146. But Kant is still more explicit, where he is explaining the nature and attributes of the understanding. He says: "We have before defined the understanding in different ways; we have called it a spontaneity of knowledge, (in opposition to the receptivity of sensibility,) a faculty of thought, or rather, a faculty of conceptions or judgments; these definitions, rightly explained, are but one. We may now characterize it as a faculty of rules. This character is more fruitful, and comes nearer to the essence of the thing: sensibility gives us forms (of intuition) and the understanding rules. The latter is always applied to the observation of phenomena in order to find in them some rule. The rules, if objective, (if, consequently, necessarily united to the knowledge of the object,) are called laws. Although we know many laws by experience, still these laws are only particular determinations of other higher laws, the highest of which (to which all the others are subjected) proceed a priori from the understanding itself, and are not taken from experience, but, on the contrary, they give to the phenomena their validity, and therefore make experience possible. The understanding, then, is not simply a faculty of making rules for itself, and comparing phenomena; it is also the legislation for nature; that is to say, that without the understanding there would be no nature, or synthetic unity of the multiplicity of phenomena according to certain rules. For the phenomena, as such, cannot exist out of us; on the contrary, they only exist in our sensibility; but this, as the object of the knowledge in an experience, with all that it can contain, is only possible in the unity of the apperception. The unity of the apperception is the transcendental foundation of the necessary legitimacy of all the phenomena in an experience; this unity of the apperception in relation to the multiplicity of the representations (in order to determine the multiplicity by starting from only one) is the rule, and the faculty of these rules is the understanding. All phenomena, then, as possible experiences, are a priori in the understanding, and from it they derive their formal possibility, in the same manner that they are pure intuitions in the sensibility, and are only possible by it in relation to the form."
In the deduction of the pure conceptions of the understanding, Kant not only pretends that the objects of our knowledge are not things in themselves, but that it is impossible that they should be, because we could not then have conceptions a priori. He adds, that the representation of all these phenomena, consequently all objects which we know, are all in the me, and are determinations of my identical me, which expresses the necessity of a universal unity of these determinations in only one and the same apperception.
147. From these passages it clearly follows that Fichte's system, or the ideal pantheism which reduces every thing to modifications of the me, accords with the principles established in the Critic of Pure Reason, and is even expressly laid down, although it does not form its principal object in that work. For the sake of impartiality I cannot do less than refer the reader to the seventeenth chapter of the third book, where I have intimated that the German philosopher attempts to explain his expressions so as to escape idealism, which he professes to refute. But this he seems to me to do only by an inconsequence.
