Primary Infection

Famous quotes containing the words primary and/or infection:

“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)

“What, then, was war? No mere discord of flags
But an infection of the common sky
That sagged ominously upon the earth”
—Robert Graves (1895–1985)
