§ 32.

It follows from our observations so far that, in spite of all the inner agreement between Kant and Plato, and of the identity of the aim that was in the mind of each, or of the world-view that inspired and led them to philosophize, Idea and thing-in-itself are not for us absolutely one and the same. On the contrary, for us the Idea is only the immediate, and therefore adequate, objectivity of the thing-in-itself, which itself, however, is the will—the will in so far as it is not yet objectified, has not yet become representation. For, precisely according to Kant, the thing-in-itself is supposed to be free from all the forms that adhere to knowledge as such. It is merely an error of Kant (as is shown in the Appendix) that he did not reckon among these forms, before all others, that of being-object-for-a-subject; for this very form is the first and most universal of all phenomenon, i.e., of all representation. He should therefore have expressly denied being-object to his thing-in-itself, for this would have protected him from that great inconsistency which was soon discovered. On the other hand, the Platonic Idea is necessarily object, something known, a representation, and precisely, but only, in this respect is it different from the thing-in-itself. It has laid aside merely the subordinate forms of the phenomenon, all of which we include under the principle of sufficient reason; or rather it has not yet entered into them. But it has retained the first and most universal form, namely that of the representation in general, that of being object for a subject. It is the forms subordinate to this (the general expression of which is the principle of sufficient reason) which multiply the Idea in particular and fleeting individuals, whose number in respect of the Idea is a matter of complete indifference. Therefore the principle of sufficient reason is again the form into which the Idea enters, since the Idea comes into the knowledge of the subject as individual. The particular thing, appearing in accordance with the principle of sufficient reason, is therefore only an indirect objectification of the thing-in-itself (which is the will). Between it and the thing-in-itself the Idea still stands as the only direct objectivity of the will, since it has not assumed any other form peculiar to knowledge as such, except that of the representation in general, i.e., that of being object for a subject. Therefore, it alone is the most adequate objectivity possible of the will or of the thing-in-itself; indeed it is even the whole thing-in-itself, only under the form of the representation. Here lies the ground of the great agreement between Plato and Kant, although in strict accuracy that of which they both speak is not the same. The particular things, however, are not an entirely adequate objectivity of the will, but this is obscured in them by those forms, whose common expression is the principle of sufficient reason, but which are the condition of knowledge such as is possible to the individual as such. If it is permitted to infer from an impossible presupposition, we should in fact no longer know particular things, or events, or change, or plurality, but apprehend only Ideas, only the grades of objectification of that one will, of the true thing-in-itself, in pure unclouded knowledge. Consequently, our world would be a nunc stans,87 if we were not, as subject of knowledge, at the same time individuals, in other words, if our perception did not come about through the medium of a body, from whose affections it starts. This body itself is only concrete willing, objectivity of will; hence it is an object among objects, and as such comes into the knowing consciousness in the only way it can, namely in the forms of the principle of sufficient reason. Consequently, it presupposes and thus introduces time and all the other forms expressed by that principle. Time is merely the spread-out and piecemeal view that an individual being has of the Ideas. These are outside time, and consequently eternal. Therefore Plato says that time is the moving image of eternity: αἰῶνoς εἰϰὼν ϰινητὴ ὁ χρóνoς. [Timaeus, 37 D.]88
