riddle to itself, thus even in inner knowledge there also exists a difference between the true being of its object and the apprehension of it in the knowing subject. Yet inner knowledge is free from two forms which belong to outer knowledge, the form of space and the form of causality, which is the means of effecting all sense-perception. On the other hand, there still remains the form of time, and that of being known and knowing in general. Accordingly in this inner knowledge the thing in itself has indeed in great measure thrown off its veil, but still does not yet appear quite naked. In consequence of the form of time which still adheres to it, every one knows his will only in its successive acts, and not as a whole, in and for itself: therefore no one knows his character a priori, but only learns it through experience and always incompletely. But yet the apprehension, in which we know the affections and acts of our own will, is far more immediate than any other. It is the point at which the thing in itself most directly enters the phenomenon and is most closely examined by the knowing subject; therefore the event thus intimately known is alone fitted to become the interpreter of all others.
For in every emergence of an act of will from the obscure depths of our inner being into the knowing consciousness a direct transition occurs of the thing in itself, which lies outside time, into the phenomenal world. Accordingly the act of will is indeed only the closest and most distinct manifestation of the thing in itself; yet it follows from this that if all other manifestations or phenomena could be known by us as directly and inwardly, we would be obliged to assert them to be that which the will is in us. Thus in this sense I teach that the inner nature of everything is will, and I call will the thing in itself. Kant's doctrine of the unknowableness of the thing in itself is hereby modified to this extent, that the thing in itself is only not absolutely and from the very foundation knowable, that yet by far the most immediate
