“a man is not really convinced of a philosophic theory when he finds that something proves it. He is only really convinced when he finds that everything proves it.”

“The sensible man,' Crow had said (to Sherlock Holmes), 'don't look to confirm what he already knows -- he looks to deny it. Finding evidence that backs up your theories ain't useful, but finding evidence that your theories are wrong is priceless. Never try to prove yourself right -- always try to prove yourself wrong instead.”

“Convince and enemy, convince him that he's wrong, is to win a bloodless battle where victory is long. A simple act of faith, is reason over might, To blow up his children would only prove him right.”

“Nobody can really be convinced of something he or she doesn't need to believe in through some biological imperative.”

“The whole work of man really seems to consist in nothing but proving to himself every minute that he is a man and not a piano key.”

“You’ve given some pretty convincing arguments, but you’re still a long way from winning me over.” “I haven’t even really tried,” he said, in a rare moment of arrogance. “When I want to, I can be very persuasive.” “Yeah? Prove it.” His lips moved toward mine. “I was hoping you’d say that.”
