This is a quote from the book "The Virtue Of Selfishness" by Ayn Rand
...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 n
o 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. In spiritual issues, a trader is a man who does not seek
to be loved for his weaknesses or flaws, only for his virtues, and who does not grant his love to the weaknesses or the flaws of others, only to their virtues.
