Famous quotes containing the word necessity:
“No use saying necessity is making a mistake.”
—Mason Cooley (b. 1927)
“For us necessity is not as of old an image without us, with whom we can do warfare; it is a magic web woven through and through us, like that magnetic system of which modern science speaks, penetrating us with a network subtler than our subtlest nerves, yet bearing in it the central forces of the world.”
—Walter Pater (1839–1894)
“Perhaps love is a compelling necessity imposed on man by God that has something to do with suffering”
—Zora Neale Hurston (1891–1960)
