“Human experience, which is constantly contradicting theory, is the great test of truth. A system, built upon the discoveries of a great many minds, is always of more strength, than what is produced by the mere workings of any one mind, which, of itself, can do very little. There is not so poor a book in the world that would not be a prodigious effort were it wrought out entirely by a single mind, without the aid of prior investigators.”

“Think of all the nonsense you had to learn in psychology courses. None of which was testable. None of which was measurable. We had behaviorism, Freudian psychology, all of these theories that you learn in psychology. Totally untestable. Now, we can test it, because physics allows us to calculate energy flows in the brain.”

“The NSF study projected a shortfall of 675,000 scientists and engineers without considering the future demand for such individuals in the marketplace. It simply observed a decline in the number of 22-year-olds and projected that this demographic trend would result in a huge shortfall. This could be termed the supply-side theory of labor market analysis. But making labor market projections without considering the demand side of the equation doesn't pass the laugh test with experts in the field.”

“But when men have realized that time has upset many fighting faiths, they may come to believe...that the best test of truth is the power of the thought to get itself accepted in the competition of the market... That at any rate is the theory of our constitution.”

“One of the greatest sources of problems in our society arises from people having loads of wrong theories in their heads - often theories that are critical of others - that they won't test by speaking to the relevant people about them. Instead, they talk behind people's backs, which leads to pervasive misinformation.”

“The material which a scientist actually has at his disposal, his laws, his experimental results, his mathematical techniques, his epistemological prejudices, his attitude towards the absurd consequences of the theories which he accepts, is indeterminate in many ways, ambiguous, and never fully separated from the historical background . This material is always contaminated by principles which he does not know and which, if known, would be extremely hard to test.”

“The test of science is not whether you are reasonable—there would not be much of physics if that was the case—the test is whether it works. And the great point about Newton’s theory of gravitation was that it worked, that you could actually say something about the motion of the moon without knowing very much about the constitution of the Earth.”

“Every genuine test of a theory is an attempt to falsify it, or to refute it.”

“I was never a prisoner of any theory. What guided me were reason and reality. The acid test I applied to every theory or scheme was: Would it work? The acid test is in performance, not promises. It is not from weakness that one commands respect. As long as the leaders take care of their people, they will obey the leaders.”

“No theory of government was ever given a fairer test or a more prolonged experiment in a democratic country than democratic socialism received in Britain. Yet it was a miserable failure in every respect... To cure the British disease with socialism was like trying to cure leukemia with leeches.”

“Our assumption is that God has not revealed all there is to know in the spiritual area any more than he has in these other areas. We, therefore, need to experiment in this area and, like scientists who work in other areas, develop and test theories in order to gain greater understanding”
