Famous quotes containing the word source:
“Because relationships are a primary source of self-esteem for girls and women, daughters need to know they will not lose our love if they speak up for what they want to tell us how they feel about things. . . . Teaching girls to make specific requests, rather than being indirect and agreeable, will help them avoid the pitfalls of having to be manipulative and calculating to get what they want.”
—Jeanne Elium (20th century)
“As a means of contrast with the sublime, the grotesque is, in our view, the richest source that nature can offer.”
—Victor Hugo (1802–1885)
“As soon as man began considering himself the source of the highest meaning in the world and the measure of everything, the world began to lose its human dimension, and man began to lose control of it.”
—Václav Havel (b. 1936)
