Necessity [is] the mother of invention.
GEORGE FARQUHAR, The Twin Rivals
Necessity first mothered invention. Now invention has little ones of her own, and they look just like grandma.
E.B. WHITE, The New Yorker, Jun. 19, 1937
Necessity knows no rules.
Necessity never made a good bargain.
BENJAMIN FRANKLIN, Poor Richard's Almanac
Necessity is the plea for every infringement of human freedom. It is the argument of tyrants; it is the creed of slaves.
WILLIAM PITT, speech, Nov. 18, 1783
Necessity makes an honest man a knave.
DANIEL DEFOE, Serious Reflections of Robinson Crusoe
Necessity hath no law. Feigned necessities, imaginary necessities ... are the greatest cozenage that men can put upon the Providence of God, and make pretences to break known rules by.
OLIVER CROMWELL, speech to Parliament, Sept. 12, 1654
