Famous quotes containing the word necessity:
“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 (17671845)
“Teach thy necessity to reason thus:
There is no virtue like necessity.”
—William Shakespeare (15641616)
