Nietzsche's break with Schopenhauer rests on precisely this point; it is a matter of knowing whether the will is unitary or multiple.

Things never pass where you think, nor along the paths you think

belief is necessarily something false that diverts and suffocates effective production

The self is only a threshold, a door, a becoming between two multiplicities

What interests us in operations of striation and smoothing are precisely the passages or combinations: how the forces at work within space continually striate it, and how in the course of its striation it develops other forces and emits new smooth spaces.

Philosophy is not in a state of external reflection on other domains, but in a state of active and internal alliance with them, and it is neither more abstract nor more difficult.

The plane of consistency is the abolition of all metaphor; all that consists is Real.
