Famous quotes containing the word necessity:
“It is the hour when stink and sweat
Subside to let the flesh forget
Affinity for brick and lathe,
The cold necessity to bathe
And certain things one would forget.”
—Allen Tate (1899–1979)
“Mr. Speaker, at a time when the nation is again confronted with necessity for calling its young men into service in the interests of National Security, I cannot see the wisdom of denying our young women the opportunity to serve their country.”
—Lyndon Baines Johnson (1908–1973)
“Old-fashioned determinism was what we may call hard determinism. It did not shrink from such words as fatality, bondage of the will, necessitation, and the like. Nowadays, we have a soft determinism which abhors harsh words, and, repudiating fatality, necessity, and even predetermination, says that its real name is freedom; for freedom is only necessity understood, and bondage to the highest is identical with true freedom.”
—William James (1842–1910)
