Who said “Madness is something rare in individuals — but in groups, parties, peoples, epochs it is…”?

“In the past, men created witches; now they create mental patients.”

“The world has always gone through periods of madness so as to advance a bit on the road to reason.”

“One who shows signs of mental aberration is, inevitably, perhaps, but cruelly, shut off from familiar, thoughtless intercourse, partly excommunicated; his isolation is unwittingly proclaimed to him on every countenance by curiosity, indifference, aversion, or pity, and in so far as he is human enough to need free and equal communication and feel the lack of it, he suffers pain and loss of a kind and degree which others can only faintly imagine, and for the most part ignore.”

“And what is an authentic madman? It is a man who preferred to become mad, in the socially accepted sense of the word, rather than forfeit a certain superior idea of human honor. So society has strangled in its asylums all those it wanted to get rid of or protect itself from, because they refused to become its accomplices in certain great nastinesses. For a madman is also a man whom society did not want to hear and whom it wanted to prevent from uttering certain intolerable truths.”

“In a completely sane world, madness is the only freedom!”

“Morality is herd instinct in the individual.”

“There is more wisdom in your body than in your deepest philosophy.”

“Of all that is written, I love only what a man has written with his own blood.”

“What is good? All that heightens the feeling of power, the will to power, power itself in man.”

“The true man wants two things: danger and play. For that reason he wants woman, as the most dangerous toy.”

“The surest way to corrupt a youth is to instruct him to hold in higher esteem those who think alike than those who think differently.”
