Famous quotes containing the words primary and/or register:
“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)
“Every new baby is a blind desperate vote for survival: people who find themselves unable to register an effective political protest against extermination do so by a biological act.”
—Lewis Mumford (1895–1990)
