“In any case, frequent punishments are a sign of weakness or slackness in the government. There is no man so bad that he cannot be made good for something. No man should be put to death, even as an example, if he can be left to live without danger to society.”

“I have never thought, for my part, that man's freedom consists in his being able to do whatever he wills, but that he should not, by any human power, be forced to do what is against his will.”

“Every man having been born free and master of himself, no one else may under any pretext whatever subject him without his consent. To assert that the son of a slave is born a slave is to assert that he is not born a man.”

“All wickedness comes from weakness. The child is wicked only because he is weak. Make him strong; he will be good. He who could do everything would never do harm.”

“It is reason which breeds pride and reflection which fortifies it; reason which turns man inward into himself; reason which separates him from everything which troubles or affects him. It is philosophy which isolates a man, and prompts him to say in secret at the sight of another suffering: 'Perish if you will; I am safe.' No longer can anything but dangers to society in general disturb the tranquil sleep of the philosopher or drag him from his bed. A fellow-man may with impunity be murdered under his window, for the philosopher has only to put his hands over his ears and argue a little with himself to prevent nature, which rebels inside him, from making him identify himself with the victim of the murder. The savage man entirely lacks this admirable talent, and for want of wisdom and reason he always responds recklessly to the first promptings of human feeling.”

“God (Nature, in my view) makes all things good; man meddles with them and they become evil. He fores one soil to yield the products of another, one tree to bear another's fruit. He confuses and confounds time, place, and natural conditions. He mutilates his dog, his horse, and his slave. He destroys and defaces all things; he loves all that is deformed and monstrous; he will have nothing as nature made it, not even himself, who must learn his paces like a saddle-horse, and be shaped to his master's taste like the trees in his garden.”

“If we assume man has been corrupted by an artificial civilization, what is the natural state? the state of nature from which he has been removed? imagine, wandering up and down the forest without industry, without speech, and without home.”
