“The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence.”

“The intangible, as you can guess, creates some decidedly strange and perceived dichotomies for scientific interpretations. Ask a scientist what the definition of electricity is and he might rattle off, “It is the physical phenomena arising from the reaction of electrons and protons…” Note the word “…phenomena…” in the above statement - it is the key word. It is used as a reference in the philosophical usage rather than as a scientific justification.”

“It is not the reverence for words, but for their meaning that determines our deepness of comprehension of a given assertion about Nature.”

“All rational knowledge is either material, and concerns some objects, or formal, and is occupied only with the form of understanding and reason itself and with the universal rules of thinking, without regard to distinctions among objects. formal philosophy is called logic. Material philosophy, however, which has to do with definite object objects and the laws to which they are subject, is divided into two parts. This is because these laws are either laws of nature or laws of freedom. The science of the former is called physics, and that of the latter ethics. The former is also called theory of nature and the latter theory of morals.”

“But women do not say 'We', except at some congress of feminists or similar formal demonstration; men say 'women', and women use the same word in referring to themselves.”

“The peculiarity of the evidence of mathematical truths is, that all the argument is on one side. There are no objections, and no answers to objections. But on every subject on which difference of opinion is possible, the truth depends on a balance to be struck between two sets of confliting reasons. Even in natural philosophy, there is always some other explanation possible of the same facts; some geocentric theory instead of heliocentric, some phlogiston instead of oxygen; and it has to be shown why that other theory cannot be the true on: and until this is shown, and until we know how it is shown, we do not understand the grounds of our opinion. But when we turn to subjects infinitely more complicated, to morals, religion, politics, social relations, and the business of life, three-fourths of the arguments for every disputed opinion consist in dispelling the appearances which favour some opinion different from it.”
