"Love, friendship, respect, admiration are the emotional response of one man to the virtues of another, the spiritual payment given in exchange for the personal, selfish pleasure which one man derives from the virtues of another man’s character. Only a brute or an altruist would claim that the appreciation of another person’s virtues is an act of selflessness, that as far as one’s own selfish interest and pleasure are concerned, it makes no difference whether one deals with a genius or a fool, whether one meets a hero or a thug, whether one marries an ideal woman or a slut."
