“I do not claim to know but at least I know when I do not know. Such men as I — you may call us philosophers or stargazers as you like — are a civic treasure, not a menace, guides to a better way of life.
“Your freedom of speech is based on the assumption that every man’s opinion is of value, and that the many are better guides than the few. But how can you boast of your free speech if you suppress mine? How can you listen to the shoemaker’s or the tanner’s view when you debate justice in the assembly, but shut me up when I express mine, though my life has been devoted to the search for truth while you have tended your own private affairs?”
The Trial of Socrates by I. F. Stone, pp. 212-213
