Primary Contact

Famous quotes containing the words primary and/or contact:

“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)

“Whatever my own practice may be, I have no doubt that it is a part of the destiny of the human race, in its gradual improvement, to leave off eating animals, as surely as savage tribes have left off eating each other when they came in contact with the more civilized.”
—Henry David Thoreau (1817–1862)
