Famous quotes containing the word expression:
“There exists in a great part of the Northern people a gloomy diffidence in the moral character of the government. On the broaching of this question, as general expression of despondency, of disbelief that any good will accrue from a remonstrance on an act of fraud and robbery, appeared in those men to whom we naturally turn for aid and counsel. Will the American government steal? Will it lie? Will it kill?—We ask triumphantly.”
—Ralph Waldo Emerson (1803–1882)
“Feminism is hated because women are hated. Anti-feminism is a direct expression of misogyny; it is the political defense of women hating.”
—Andrea Dworkin (b. 1946)
“Politics are usually the executive expression of human immaturity.”
—Vera Brittain (1896–1970)
