Famous quotes containing the word growth:
“The wind of change is blowing through the continent. Whether we like it or not, this growth of national consciousness is a political fact.”
—Harold MacMillan (1894–1986)
“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)
“The risk for a woman who considers her helpless children her “job” is that the children’s growth toward self-sufficiency may be experienced as a refutation of the mother’s indispensability, and she may unconsciously sabotage their growth as a result.”
—Letty Cottin Pogrebin (20th century)
