Famous quotes containing the word necessity:
“There is no necessity to separate the monarch from the mob; all authority is equally bad.”
—Oscar Wilde (1854–1900)
“No picture of life can have any veracity that does not admit the odious facts. A man’s power is hooped in by a necessity which, by many experiments, he touches on every side until he learns its arc.”
—Ralph Waldo Emerson (1803–1882)
“Private property is held sacred in all good governments, and particularly in our own. Yet shall the fear of invading it prevent a general from marching his army over a cornfield or burning a house which protects the enemy? A thousand other instances might be cited to show that laws must sometimes be silent when necessity speaks.”
—Andrew Jackson (1767–1845)
