Famous quotes containing the word necessity:
“The objects of a financier are, then, to secure an ample revenue; to impose it with judgment and equality; to employ it economically; and, when necessity obliges him to make use of credit, to secure its foundations in that instance, and for ever, by the clearness and candour of his proceedings, the exactness of his calculations, and the solidity of his funds.”
—Edmund Burke (1729–1797)
“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–?)
“No use saying necessity is making a mistake.”
—Mason Cooley (b. 1927)
