Famous quotes containing the word country:
“In schools all over the world, little boys learn that their country is the greatest in the world, and the highest honor that could befall them would be to defend it heroically someday. The fact that empathy has traditionally been conditioned out of boys facilitates their obedience to leaders who order them to kill strangers.”
—Myriam Miedzian, U.S. author. Boys Will Be Boys, ch. 3 (1991)
“The naturalistic literature of this country has reached such a state that no family of characters is considered true to life which does not include at least two hypochondriacs, one sadist, and one old man who spills food down the front of his vest.”
—Robert Benchley (1889–1945)
