Famous quotes containing the word defense:
“Though a censure lies against those who are poor and proud, yet is Pride sooner to be forgiven in a poor person than in a rich one; since in the latter it is insult and arrogance; in the former, it may be a defense against temptations to dishonesty; and, if manifested on proper occasions, may indicate a natural bravery of mind, which the frowns of fortune cannot depress.”
—Samuel Richardson (1689–1761)
“For there is no defense for a man who, in the excess of his wealth, has kicked the great altar of Justice out of sight.”
—Aeschylus (525–456 B.C.)
“I would remind you that extremism in the defense of liberty is no vice! And let me remind you also that moderation in the pursuit of justice is no virtue!”
—Barry Goldwater (b. 1909)
