Famous quotes containing the words route and/or description:
“In the mountains the shortest route is from peak to peak, but for that you must have long legs. Aphorisms should be peaks: and those to whom they are spoken should be big and tall of stature.”
—Friedrich Nietzsche (18441900)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
