Famous quotes containing the word growth:
“You know that the nucleus of a time is not
The poet but the poem, the growth of the mind
Of the world, the heroic effort to live expressed
As victory. The poet does not speak in ruins
Nor stand there making orotund consolations.
He shares the confusions of intelligence.”
—Wallace Stevens (1879–1955)
“Sensuality often accelerates the growth of love so much that its roots remain weak and are easily pulled up.”
—Friedrich Nietzsche (1844–1900)
“Unlimited economic growth has the marvelous quality of stilling discontent while maintaining privilege, a fact that has not gone unnoticed among liberal economists.”
—Noam Chomsky (b. 1928)
