Famous quotes containing the word growth:
“Of all the wastes of human ignorance perhaps the most extravagant and costly to human growth has been the waste of the distinctive powers of womanhood after the child-bearing age.”
—Anna Garlin Spencer (1851–1931)
“A revolution is not the overturning of a cart, a reshuffling in the cards of state. It is a process, a swelling, a new growth in the race. If it is real, not simply a trauma, it is another ring in the tree of history, layer upon layer of invisible tissue composing the evidence of a circle.”
—Kate Millett (b. 1934)
“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)
