Utopia is a mixture of childish rationalism and secularized angelism.

We understand God by everything in ourselves that is fragmentary, incomplete, and inopportune.

The fact that life has no meaning is a reason to live - moreover, the only one.

Afflicted with existence, each man endures like an animal the consequences which proceed from it. Thus, in a world where everything is detestable, hatred becomes huger than the world and, having transcended its object, cancels itself out.

Those who believe in their truth -- the only ones whose imprint is retained by the memory of men -- leave the earth behind them strewn with corpses. Religions number in their ledgers more murders than the bloodiest tyrannies account for, and those whom humanity has called divine far surpass the most conscientious murderers in their thirst for slaughter.

We have convictions only if we have studied nothing thoroughly.

If a man has not, by the time he is thirty, yielded to the fascination of every form of extremism—I don't know whether he is to be admired or scorned, regarded as a saint or a corpse.
