Freedom is the fundamental character of the will, as weight is of matter... That which is free is the will. Will without freedom is an empty word.

The sole work and deed of universal freedom is therefore death, a death too which has no inner significance or filling, for what is negated is the empty point of the absolutely free self. It is thus the coldest and meanest of all deaths, with no more significance than cutting off a head of cabbage or swallowing a mouthful of water.

It is a matter of perfect indifference where a thing originated; the only question is: Is it true in and for itself?

Genuine tragedies in the world are not conflicts between right and wrong. They are conflicts between two rights.
