Famous quotes containing the word reasons:
“One who is publicly honest about himself ends up by priding himself somewhat on this honesty: for he knows only too well why he is honest—for the same reasons another person prefers illusion and dissimulation.”
—Friedrich Nietzsche (1844–1900)
“It seems to me that we have to draw the line in sibling rivalry whenever rivalry goes out of bounds into destructive behavior of a physical or verbal kind. The principle needs to be this: Whatever the reasons for your feelings you will have to find civilized solutions.”
—Selma H. Fraiberg (20th century)
“Happy the man who has been able to know the reasons for things.”
—Virgil [Publius Vergilius Maro] (70–19 B.C.)
