“Apparently, I must give you a lecture. I grimaced neither at your impudence nor at your sentiment, but at your diction and style. I condemn clichés, especially those that have been corrupted by fascists and communists. Such phrases as ‘great and noble cause’ and ‘fruits of their labour’ have been given an ineradicable stink by Hitler and Stalin and all their vermin brood. Besides, in this century of the overwhelming triumph of science, the appeal of the cause of human freedom is no longer that it is great and noble; it is more or less than that; it is essential. It is no greater or nobler than the cause of edible food or the cause of effective shelter. Man must have freedom or he will cease to exist as man. The despot, whether fascist or communist, is no longer restricted to such puny tools as the heel or the sword or even the machine gun; science has provided him weapons that can give him the planet; and only men who are willing to die for freedom have any chance of living for it.’”

“The period during which light was ‘sometimes a wave and sometimes a particle’ was a period of crisis – a period when something was wrong – and it ended only with the development of wave mechanics and the realization that light was a self-consistent entity different from both waves and particles. In the sciences, therefore, if perceptual switches accompany paradigm changes, we may not expect scientists to attest to these changes directly. Looking at the moon, the convert to Copernicanism does not say, ‘I used to see a planet, but now I see a satellite.’ That locution would imply a sense in which the Ptolemaic system had once been correct. Instead, a convert to the new astronomy says, ‘I once took the moon to be (or saw the moon as) a planet, but I was mistaken.’ That sort of statement does recur in the aftermath of scientific revolutions.”
