Famous quotes containing the word necessity:
“I complacently accepted the social order in which I was brought up. I probably would have continued in my complacency if the happy necessity of self-support had not fallen to my lot; if self-support had not deepened and widened my contacts and my experience.”
—Mary Barnett Gilson (1877–?)
“Undoubtedly if we were to reform this outward life truly and thoroughly, we should find no duty of the inner omitted. It would be employment for our whole nature.... But a moral reform must take place first, and then the necessity of the other will be superseded, and we shall sail and plow by its force alone.”
—Henry David Thoreau (1817–1862)
“Every need whose true satisfaction is denied leads by necessity to faith.”
—Johann Wolfgang Von Goethe (1749–1832)
