“It's been suggested that if the super-naturalists really had the powers they claim, they'd win the lottery every week. I prefer to point out that they could also win a Nobel Prize for discovering fundamental physical forces hitherto unknown to science. Either way, why are they wasting their talents doing party turns on television?By all means let's be open-minded, but not so open-minded that our brains drop out.”

“Be open minded, but not so open minded that your brains fall out.”

“It pays to keep an open mind, but not so open your brains fall out.”

“Two girls called me closed minded. I tell them that they are so open-minded their brains leaked out.”

“The really clever thing, in affairs of this sort, is not to win a woman already desired by everyone, but to discover such a prize while she is still unknown.”

“If you're too open-minded; your brains will fall out.”

“Impossible doesn't mean very difficult, very difficult is winning the Nobel Prize, impossible is eating the sun.”

“If you all claim to be open-minded individuals, why do you find it hard to comprehend and live with different views of others?”

“I rapidly discovered that Aristotle had known almost no mechanics at all. … How could his characteristic talents have deserted him so systematically when he turned to the study of motion and mechanics? Equally, if his talents had so deserted him, why had his writings in physics been taken so seriously for so many centuries after his death? … I was sitting at my desk with the text of Aristotle's Physics open in front of me… Suddenly the fragments in my head sorted themselves out in a new way, and fell into place together. My jaw dropped, for all at once Aristotle seemed a very good physicist indeed, but of a sort I'd never dreamed possible. Now I could understand why he had said what he'd said, and what his authority had been. Statements that had previously seemed egregious mistakes, now seemed at worst near misses within a powerful and generally successful tradition. That sort of experience -- the pieces suddenly sorting themselves out and coming together in a new way -- is the first general characteristic of revolutionary change that I shall be singling out after further consideration of examples. Though scientific revolutions leave much piecemeal mopping up to do, the central change cannot be experienced piecemenal, one step at a time. Instead, it involves some relatively sudden and unstructured transformation in which some part of the flux of experience sorts itself out differently and displays patterns that were not visible before.”

“In her book, Philosophy in a New Key, Susanne Langer remarks that certain ideas burst upon the intellectual landscape with a tremendous force. They resolve so many fundamental problems at once that they seem also to promise that they will resolve all fundamental problems, clarify all obscure issues. Everyone snaps them up as the open sesame of some new positive science, the conceptual center-point around which a comprehensive system of analysis can be built. The sudden vogue of such a grande ideé, crowding out almost everything else for a while, is due, she says, “to the fact that all sensitive and active minds turn at once to exploiting it. We try it in every connection, for every purpose, experiment with possible stretches of its strict meaning, with generalizations and derivatives.””
