166 THE WORLD AS WILL. bk. ii.
seeing all the prevalent fundamental views endangered, he sought safety in the old and already exploded absurdities.
We know that multiplicity in general is necessarily conditioned by space and time, and is only thinkable in them. In this respect they are called the principium individuationis. But we have found that space and time are forms of the principle of sufficient reason. In this principle all our knowledge a priori is expressed, but, as we showed above, this a priori knowledge, as such, only applies to the knowableness of things, not to the things themselves, i.e., it is only our form of knowledge, it is not a property of the thing-in-itself. The thing-in-itself is, as such, free from all forms of knowledge, even the most universal, that of being an object for the subject. In other words, the thing-in-itself is something altogether different from the idea. If, now, this thing-in-itself is the will, as I believe I have fully and convincingly proved it to be, then, regarded as such and apart from its manifestation, it lies outside time and space, and therefore knows no multiplicity, and is consequently one. Yet, as I have said, it is not one in the sense in which an individual or a concept is one, but as something to which the condition of the possibility of multiplicity, the principium individuationis, is foreign. The multiplicity of things in space and time, which collectively constitute the objectification of will, does not affect the will itself, which remains indivisible notwithstanding it. It is not the case that, in some way or other, a smaller part of will is in the stone and a larger part in the man, for the relation of part and whole belongs exclusively to space, and has no longer any meaning when we go beyond this form of intuition or perception. The more and the less have application only to the phenomenon of will, that is, its visibility, its objectification. Of this there is a higher grade in the plant than in the stone; in the animal a higher grade than in the plant: indeed, the passage of will into visibility, its
