Famous quotes containing the word necessity:

—Tennessee Williams (1914–1983)

But this distinction I have not used, nor indeed have ever heard before, nor could I think any man could make stoical and Christian two kinds of necessity, though they may be two kinds of doctrine”
—Thomas Hobbes (1579–1688)
“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.”
