Perhaps I know best why it is man alone who laughs; he alone suffers so deeply that he had to invent laughter. - Friedrich Nietzsche

O man! Attend!
What does deep midnight's voice contend?
I slept my sleep,
And now awake at dreaming's end:
The world is deep,
And deeper than day can comprehend.
Deep is its woe,
Joy — deeper than heart's agony:
Woe says: Fade! Go!
But all joy wants eternity,
Wants deep, wants deep eternity.

A politician divides mankind into two classes: tools and enemies.

Supposing that what is at any rate believed to be the 'truth' really is true, and the meaning of all culture is the reduction of the beast of prey 'man' to a tame and civilized animal, a domestic animal, then one would undoubtedly have to regard all those instincts of reaction and ressentiment through whose aid the noble races and their ideals were finally confounded and overthrown as the actual instruments of culture; which is not to say that the bearers of these instincts themselves represent culture. Rather is the reverse not merely probable — no! today it is palpable! These bearers of the oppressive instincts that thirst for reprisal, the descendants of every kind of European and non-European slavery, and especially of the entire pre-Aryan populace — they represent the regression of mankind! These 'instruments of culture' are a disgrace to man and rather an accusation and counterargument against 'culture' in general!
