“The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error.”
― John Stuart Mill, On Liberty

“Peace is not the absence of war, it is a virtue, a state of mind, a disposition of benevolence, confidence, justice.”
― Baruch Spinoza

“A society that puts equality before freedom will get neither. A society that puts freedom before equality will get a high degree of both.”
― Milton Friedman

“I do not know how to teach philosophy without becoming a disturber of the peace.”
― Baruch Spinoza
