Theory Quotes

“I can have little patience with those who oppose ... the theory of evolution or what are called "mechanistic" explanations of the phenomena of life because of certain moral consequences which at first seem to follow from these theories, and still less with those who regard it as irrelevant or impious to ask certain questions at all. By refusing to face the facts , the conservative only weakens his own position.”

“Human rights are an aspect of natural law, a consequence of the way the universe works, as solid and as real as photons or the concept of pi. The idea of self- ownership is the equivalent of Pythagoras' theorem, of evolution by natural selection, of general relativity, and of quantum theory. Before humankind discovered any of these, it suffered, to varying degrees, in misery and ignorance.”

“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 confusion between temperament and character has had serious consequences for ethical theory. Preferences with regard to differences in temperament are mere matters of subjective taste. But differences in character are ethically of the most fundamental importance.”

“We have seen that in certain respects operant reinforcement resembles the natural selection of evolutionary theory. Just as genetic characteristics which arise as mutations are selected or discarded by their consequences, so novel forms of behavior are selected or discarded through reinforcement.”

If it breaks a law of physics, it knows it's doing so and follows up the consequences. If it invents a society of aliens, it does so with some respect for and knowledge of the social sciences and what you might call social probabilities. And some of it is literarily self-aware enough to treat its metaphors as metaphors.”

“Natural Selection is not Evolution. Yet, ever since the two words have been in common use, the theory of Natural Selection has been employed as a convenient abbreviation for the theory of Evolution by means of Natural Selection, put forward by Darwin and Wallace. This has had the unfortunate consequence that the theory of Natural Selection itself has scarcely ever, if ever, received separate consideration.”

“[How to think about a problem:] The first step is to make the problem specific . . . ; The second step is to form theories freely of how to rid yourself of that burden . . . ; The third step is to develop in foresight the consequences of your proposals . . . ; The fourth and final step in thinking is to compare the consequences of your proposals to see which is best in the light of your scheme of life as a whole . . . ; Whether you choose a vacation or a spouse, a party or a candidate, a cause to contribute to or a creed to live by - think!”
