“What good would it be to possess the whole universe if one were its only survivor?”

“The sword wears out its sheath, as it is sometimes said. That is my story. My passions have made me live, and my passions have killed me. What passions, it may be asked. Trifles, the most childish things in the world. Yet they affected me as much as if the possessions of Helen, or the throne of the Universe, had been at stake.”

“If one divided all of human science into two parts - the one common to all men, the other particular to the learned - the latter would be quite small in comparison with the former. But we are hardly aware of what is generally attained, because it is attained without thought and even before the age of reason; because, moreover, learning is noticed only by its differences, and as in algebraic equations, common quantities count for nothing.”

“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.”

“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.”

“My illusions about the world caused me to think that in order to benefit by my reading I ought to possess all the knowledge the book presupposed. I was very far indeed from imagining that often the author did not possess it himself, but had extracted it from other books, as and when he needed it. This foolish conviction forced me to stop every moment, and to rush incessantly from one book to another; sometimes before coming to the tenth page of the one I was trying to read I should, by this extravagant method, have had to run through whole libraries. Nevertheless I stuck to it so persistently that I wasted infinite time, and my head became so confused that I could hardly see or take in anything.”

“The word ‘slavery’ and ‘right’ are contradictory, they cancel each other out. Whether as between one man and another, or between one man and a whole people, it would always be absurd to say: "I hereby make a covenant with you which is wholly at your expense and wholly to my advantage; I will respect it so long as I please and you shall respect it as long as I wish.”
