Famous quotes containing the words potential and/or problems:
“Silence is as full of potential wisdom and wit as the unhewn marble of great sculpture. The silent bear no witness against themselves.”
—Aldous Huxley (1894–1963)
“The problems of the world, AIDS, cancer, nuclear war, pollution, are, finally, no more solvable than the problem of a tree which has borne fruit: the apples are overripe and they are falling—what can be done?... Nothing can be done, and nothing needs to be done. Something is being done—the organism is preparing to rest.”
—David Mamet (b. 1947)
