“There are three people one can never reason with: a drunk, a crazy person, and a fool.”

“Crazy people are not crazy if one accepts their reasoning.”

“If one person tells you you're a horse , they are crazy. If three people tell you you're a horse, There's conspiracy afoot. If ten people tell you you're a horse,it's time to buy a saddle”

“The indispensability of reason does not imply that individual people are always rational or are unswayed by passion and illusion. It only means that people are capable of reason, and that a community of people who choose to perfect this faculty and to exercise it openly and fairly can collectively reason their way to sounder conclusions in the long run. As Lincoln observed, you can fool all of the people some of the time, and you can fool some of the people all of the time, but you can't fool all of the people all of the time.”

“You can fool a lot of the people some of the time, and a few of the people most of the time, but the only person you can fool all of the time is yourself.”

“People are all crazy... but the craziest are the ones who never allow themselves to be crazy.”
