Robert A. Heinlein on Science

"Never worry about theory as long as the machinery does what it's supposed to do."

"In the first place there isn’t a distinguished anthropologist in the world but what you’ll find one equally distinguished who will call him a diamond-studded liar. They can’t agree on the simplest elements of their alleged science."

"I think that science fiction, even the corniest of it, even the most outlandish of it, no matter how badly it's written, has a distinct therapeutic value because all of it has as its primary postulate that the world does change. I cannot overemphasize the importance of that idea."

"There is no subject inappropriate for scientific research. Johann, we’ve let you fellows have a monopoly of such matters for too long. The most serious questions in the world have been left to faith or speculation. It is time for scientists to cope with them, or admit that science is no more than pebble counting."

"In this complex world, science, the scientific method, and the consequences of the scientific method are central to everything the human race is doing and to wherever we are going. If we blow ourselves up we will do it by misapplication of science; if we manage to keep from blowing ourselves up, it will be through intelligent application of science."

"There are but two ways of forming an opinion in science. One is the scientific method; the other, the scholastic. One can judge from experiment, or one can blindly accept authority. To the scientific mind, experimental proof is all important and theory is merely a convenience in description, to be junked when it no longer fits. To the academic mind, authority is everything and facts are junked when they do not fit theory laid down by authority."
