Famous quotes containing the word require:
“Let’s call something a rigid designator if in every possible world it designates the same object, a non-rigid or accidental designator if that is not the case. Of course we don’t require that the objects exist in all possible worlds.... When we think of a property as essential to an object we usually mean that it is true of that object in any case where it would have existed. A rigid designator of a necessary existent can be called strongly rigid.”
—Saul Kripke (b. 1940)
“... the most extreme conditions require the most extreme response, and for some individuals, the call to that response is vitality itself.... The integrity and self-esteem gained from winning the battle against extremity are the richest treasures in my life.”
—Diana Nyad (b. 1949)
“Cities give not the human senses room enough. We go out daily and nightly to feed the eyes on the horizon, and require so much scope, just as we need water for our bath.”
—Ralph Waldo Emerson (1803–1882)
