“An unexamined idea, to paraphrase Socrates, is not worth having and a society whose ideas are never explored for possible error may eventually find its foundations insecure.”

“Socrates had it wrong; it is not the unexamined but finally the uncommitted life that is not worth living.”

“Socrates told us, "the unexamined life is not worth living." I think he's calling for curiosity, more than knowledge. In every human society at all times and at all levels, the curious are at the leading edge.”

“Every revolutionary idea seems to evoke three stages of reaction. They may be summed up by the phrases: (1) It's completely impossible. (2) It's possible, but it's not worth doing. (3) I said it was a good idea all along.”

“The difference between Socrates and Jesus is that no one had ever been put to death in Socrates' name. And that is because Socrates' ideas were never made law. Law, in whatever name, protects privilege.”

“An unexamined life is not worth living, and an unexamined faith is not worth holding.”
