Famous quotes containing the word permanent:
“It takes place ... always without permanent form, though ancient and familiar as the sun and moon, and as sure to come again.”
—Henry David Thoreau (1817–1862)
“The chief element in the art of statesmanship under modern conditions is the ability to elucidate the confused and clamorous interests which converge upon the seat of government. It is an ability to penetrate from the naïve self-interest of each group to its permanent and real interest.... Statesmanship ... consists in giving the people not what they want but what they will learn to want.”
—Walter Lippmann (1889–1974)
“Cynicism makes things worse than they are in that it makes permanent the current condition, leaving us with no hope of transcending it. Idealism refuses to confront reality as it is but overlays it with sentimentality. What cynicism and idealism share in common is an acceptance of reality as it is but with a bad conscience.”
—Richard Stivers, U.S. sociologist, educator. The Culture of Cynicism: American Morality in Decline, ch. 1, Blackwell (1994)
