“Discovery, they believe, is inevitable. So they just try to do it first. That's the game in science.”

“Science is the search for the truth--it is not a game in which one tries to beat his opponent, to do harm to others. We need to have the spirit of science in international affairs, to make the conduct of international affairs the effort to find the right solution, the just solution of international problems, and not an effort by each nation to get the better of other nations, to do harm to them when it is possible. I believe in morality, in justice, in humanitarianism.”

“The most exciting phrase to hear in science, the one that heralds the most discoveries, is not "Eureka!" (I found it!) but 'That's funny...”

“All scholarship, like all science, is an ongoing, open-ended discussion in which all conclusions are tentative forever, the principal value and charm of the game being the discovery of the totally unexpected.”

“As the popularity of science-fiction increases, so inevitably does the volume of clownish imprecation against it.”

“It is the presence of doubt and the discovery of truth to answer that doubt that is the key to the whole process. Doubt is the key to spirituality, just as doubt is the key to science.”
