We lived like that “Happy Family“ you sometimes see in traveling zoos: a lion caged with a lamb. It is a startling exhibit but the lamb has to be rep… - Robert A. Heinlein

“People tend to fall into three psychological types, all differently motivated. There is the type, motivated by economic factors, money...And there is the type motivated by ‘face,’ or pride. This type is a spender, fighter, boaster, lover, sportsman, gambler; he has a will to power and an itch for glory. And there is the professional type, which claims to follow a code of ethics rather than simply seeking money or glory—priests and ministers, teachers, scientists, medical men, some artists and writers. The idea is that such a man believes that he is devoting his life to some purpose more important than his individual self. You follow me?”

But there seems to have been an actual decline in rational thinking. The United States had become a place where entertainers and professional athletes were mistaken for people of importance. They were idolized and treated as leaders; their opinions were sought on everything and they took themselves just as seriously — after all, if an athlete is paid a million or more a year, he knows he is important … so his opinions of foreign affairs and domestic policies must be important, too, even though he proves himself to be both ignorant and subliterate every time he opens his mouth. (Most of his fans were just as ignorant and unlettered; the disease was spreading.)

Everything is theoretically impossible, until it is done. One could write a history of science in reverse by assembling the solemn pronouncements of highest authority about what could not be done and could never happen.
