Principium individuationis

Definition and stakes

Portrait of Arthur Schopenhauer Arthur Schopenhauer The World as Will and Representation (1819)

For only in the case of a few is the mere knowledge which, seeing through the principium individuationis, first produces perfect goodness of disposition and universal love of humanity, and finally enables them to regard all the suffering of the world as their own; only in the case of a few, I say, is this knowledge sufficient to bring about the denial of the will.

Portrait of Arthur Schopenhauer Arthur Schopenhauer The World as Will and Representation…

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.
