Famous quotes containing the words primary and/or decay:
“A fact is a proposition of which the verification by an appeal to the primary sources of our knowledge or to experience is direct and simple. A theory, on the other hand, if true, has all the characteristics of a fact except that its verification is possible only by indirect, remote, and difficult means.”
—Chauncey Wright (1830–1875)
“It has taken me nearly twenty years of studied self-restraint, aided by the natural decay of my faculties, to make myself dull enough to be accepted as a serious person by the British public; and I am not sure that I am not still regarded as a suspicious character in some quarters.”
—George Bernard Shaw (1856–1950)
