"A technique succeeds in mathematical physics, not by a clever trick, or a happy accident, but because it expresses some aspect of a physical truth."

"The basic notion underlying USENET is the flame."

"Everything has got a moral if you can only find it."

"Truth never comes into the world but like a bastard, to the ignominy of him that brought her birth."

"The least deviation from truth will be multiplied later."

"Fine art and pizza delivery, what we do falls neatly in between!"

"I like less the story that a frog if put in cold water will not bestir itself if that water is heated up slowly and gradually and will in the end let itself be boiled alive, too comfortable with continuity to realize that continuous change at some point may become intolerable and demand a change in behavior."

"The road to truth is long, and lined the entire way with annoying bastards"

"I can be expected to look for truth but not to find it."

"When I give food to the poor, they call me a saint. When I ask why the poor have no food, they call me a communist."

"I never write Metropolis for seven cents because I can get the same price for city. I never write policeman because I can get the same money for cop."

"Scientists are the easiest to fool. They think in straight, predictable, directable, and therefore misdirectable, lines. The only world they know is the one where everything has a logical explanation and things are what they appear to be. Children and conjurors--they terrify me. Scientists are no problem; against them I feel quite confident."

"The folly of mistaking a paradox for a discovery, a metaphor for a proof, a torrent of verbiage for a spring of capital truths, and oneself for an oracle, is inborn in us."

"I never could tell a lie that anybody would doubt, nor a truth that anybody would believe."

"A lie can travel halfway round the world while the truth is putting on its shoes."

"Science would be ruined if (like sports) it were to put competition above everything else, and if it were to clarify the rules of competition by withdrawing entirely into narrowly defined specialties. The rare scholars who are nomads-by-choice are essential to the intellectual welfare of the settled disciplines."

"Books must follow sciences, and not sciences books."

"The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work."
