Famous quotes containing the word qualities:
“Adolescents swing from euphoric self-confidence and a kind of narcissistic strength in which they feel invulnerable and even immortal, to despair, self-emptiness, self-deprecation. At the same time they seem to see an emerging self that is unique and wonderful, they suffer an intense envy which tears narcissism into shreds, and makes other people’s qualities hit them like an attack of lasers.”
—Terri Apter (20th century)
“As there is a degree of depravity in mankind which requires a certain circumspection and distrust, so there are qualities in human nature which justify a certain portion of esteem and confidence.”
—James Madison (1751–1836)
“Our good qualities expose us more to hatred and persecution than all the ill we do.”
—François, Duc De La Rochefoucauld (1613–1680)
