“There is no evildoer who could not be made good for something. ”

“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.”

“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.”

“I know the feelings of my heart, and I know men. I am not made like any of those I have seen; I venture to believe that I am not made like any of those who are in existence. If I am not better, at least I am different. Whether Nature has acted rightly or wrongly in destroying the mould in which she cast me, can only be decided after I have been read.”

“In truth, laws are always useful to those with possessions and harmful to those who have nothing; from which it follows that the social state is advantageous to men only when all possess something and none has too much.”

“To discover the rules of society that are best suited to nations, there would need to exist a superior intelligence, who could understand the passions of men without feeling any of them, who had no affinity with our nature but knew it to the full, whose happiness was independent of ours, but who would nevertheless make our happiness his concern, who would be content to wait in the fullness of time for a distant glory, and to labour in one age to enjoy the fruits in another. Gods would be needed to give men laws.”

“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.”
