Famous quotes containing the word advantages:
“When the manipulations of childhood are a little larceny, they may grow and change with the child into qualities useful and admire in the grown-up world. When they are the futile struggle for love and concern and protection, they may become the warped and ruthless machinations of adults who seek in the advantages of power what they could never win as children.”
—Leontine Young (20th century)
“There is no one thoroughly despicable. We cannot descend much lower than an idiot; and an idiot has some advantages over a wise man.”
—William Hazlitt (1778–1830)
“For, the advantages which fashion values, are plants which thrive in very confined localities, in a few streets, namely. Out of this precinct, they go for nothing; are of no use in the farm, in the forest, in the market, in war, in the nuptial society, in the literary or scientific circle, at sea, in friendship, in the heaven of thought or virtue.”
—Ralph Waldo Emerson (1803–1882)
