3. REMODELLING OF THE CONCEPTIONS OF EXPERIENCE.—Metaphysics, according to Herbart, is the science of that which is conceivable in experience. Our view thus far has been a twofold one. On the one side we hold fast to the opinion that the single basis of philosophy is experience, and on the other side, scepticism has shaken the credibility of experience. The point now is to transform this scepticism into a definite knowledge of metaphysical problems. Conceptions from experience crowd upon us, which cannot be thoughts, _i. e._ they may indeed be thought by the ordinary understanding, but this thinking is obscure and confused, and does not separate nor compare opposing characteristics. But an acute process of thought, a logical analysis, will find in the conceptions of experience (_e. g._ space, time, becoming, motion, &c.) contradictions and characteristics, which are totally inconsistent with each other. What now is to be done? We may not reject these conceptions, for they are given, and beyond the given we cannot step; we cannot retain them, for they are inconceivable and cannot logically be established. The only way of escape which remains to us is to remodel them. _To remodel the conceptions of experience_, to eliminate their contradictions, is the proper act of speculation. Scepticism has brought to light the more definite problems which involve a contradiction, and whose solution it therefore belongs to metaphysics to attempt; the most important of these are the problems of inherence, change, and the Ego.
The relation between Herbart and Hegel is very clear at this point. Both are agreed respecting the contradictory nature of the determinations of thought, and the conceptions of experience. But from this point they separate. It is the nature of these conceptions as of every thing, says Hegel, to be an inner contradiction; becoming, for instance, is essentially the unity of being, and not being, &c. This is impossible, says Herbart, on the other side, so long as the principle of contradiction is valid; if the conceptions of experience contain inner contradictions, this is not the fault of the objective world, but of the representing subject who must rectify his false apprehension by remodelling these conceptions, and eliminating the contradiction. Herbart thus charges the philosophy of Hegel with empiricism, because it receives from experience these contradictory conceptions unchanged, and not only regards these as established, but even goes so far as to metamorphose logic on their account, and this simply because they are given in experience, though their contradictory nature is clearly seen. Hegel and Herbart stand related to each other as Heraclitus and Parmenides (_cf._ § § VI. and VII.)
