That which does not kill us makes us stronger.

Hope in reality is the worst of all evils because it prolongs the torments of man.

Watch them clamber, these swift monkeys! They clamber over one another and thus drag one another into the mud and the depth. They all want to get to the throne: that is their madness — as if happiness sat on the throne. Often, mud sits on the throne — and often the throne also on mud. Mad they all appear to me, clambering monkeys and overardent. Foul smells their idol, the cold monster: foul, they smell to me altogether, these idolators.

The anarchist and the Christian have a common origin.

Christianity has taken the part of all the weak, the low, the botched; it has made an ideal out of antagonism to all the self preservative instincts of sound life; it has corrupted even the faculties of those natures that are intellectually most vigorous, by representing the highest intellectual values as sinful, as misleading, as full of temptation.
