To predict the behavior of ordinary people in advance, you only have to assume that they will always try to escape a disagreeable situation with the smallest possible expenditure of intelligence.
Insanity in individuals is something rare - but in groups, parties, nations and epochs, it is the rule.
But thus do I counsel you, my friends: distrust all in whom the impulse to punish is powerful!
Friedrich Nietzsche, Also Sprach Zarathustra, Chapter 29
No price is too high to pay for the privilege of owning yourself.
To forget one's purpose is the commonest form of stupidity.
You need chaos in your soul to give birth to a dancing star.
There is always some madness in love. But there is also always some reason in madness.
Friedrich Nietzsche, "On Reading and Writing"
What is done out of love always takes place beyond good and evil.
Friedrich Nietzsche, Beyond Good and Evil, Aphorism 153
The greatest danger that always hovered over humanity and still hovers over it is the eruption of madness - which means the eruption of arbitrariness in feeling, seeing and hearing, the enjoyment of the mind's lack of discipline, the joy in human unreason. Not truth and certainty are the opposite of the world of the madman, but the universality and the universal binding force of a faith; in sum, the non-arbitrary character of judgements... Thus the virtuous intellects are needed - oh, let me use the most unambiguous word - what is needed is virtuous stupidity, stolid metronomes for the slow spirit, to make sure that the faithful of the great shared faith stay together and continue their dance... We others are the exception and the danger - and we need eternally to be opposed. - Well, there actually are things to be said in favor of the exception, provided that it never wants to become the rule.
Friedrich Nietzsche, The Gay Science, s. 76
Nietzsche's influence remains substantial within and beyond philosophy, notably in existentialism, nihilism and postmodernism. His style and radical questioning of the value and objectivity of truth have resulted in much commentary and interpretation, mostly in the continental tradition. His key ideas include the death of God, perspectivism, the Übermensch, amor fati, the eternal recurrence, and the will to power. Central to his philosophy is the idea of "life-affirmation", which involves an honest questioning of all doctrines that drain life's expansive energies, however socially prevalent those views might be.[
