The extension of Black's method by the physicist Lavoisier led to the downfall of the purely qualitative theory of phlogiston, and gave to chemistry the true methods of investigation, and its first great quantitative law-the law of conservation of matter. (J. R. Partington)

Rhetoric, it seems, is a producer of persuasion for belief, not for instruction in the matter of right and wrong ... And so the rhetorician's business is not to instruct a law court or a public meeting in matters of right and wrong, but only to make them believe. View quote

The physicist who states a law of nature with the aid of a mathematical formula is abstracting a real feature of a real material world, even if he has to speak of numbers, vectors, tensors, state-functions, or whatever to make the abstraction. View quote

The world has arisen in some way or another. How it originated is the great question, and Darwin's theory, like all other attempts to explain the origin of life, is thus far merely conjectural. I believe he has not even made the best conjecture possible in the present state of our knowledge. View quote

I shall add that only he who has decided to commit suicide can start a nuclear war in the hope of emerging a victor from it. No matter what the attacker might possess, no matter what method of unleashing nuclear war he chooses, he will not attain his aims. Retribution will inevitably ensue. View quote

Few persons can be made to believe that it is not quite an easy thing to invent a method of secret writing which shall baffle investigation. Yet it may be roundly asserted that human ingenuity cannot concoct a cipher which human ingenuity cannot resolve. View quote
