“Humans. Violent but peace-loving. Passionate but cerebral. Humane but cruel. Impulsive but calculating. Generous but selfish. Humans. Altogether a contradictory and deeply flawed species. And yet...And yet, somehow I knew that they represented the best hope of the galaxy. Perhaps the only hope.”

“[On Schopenhauer in Black and White] Schopenhauer's views of love are flawed. Love can't be merely an illusion of the mind to aid in procreation, but the path to redemption for an otherwise violently selfish species. Past human greatness has proven that when challenged, love can overpower impulsive instinct, and in essence, the vilest aspects of our nature.”

“Faith is a marvel, and yet no human being is excluded from it; for that in which all human life is united is passion, and faith is a passion.”

“Human beings appear to be sufficiently selfish and calculating to be capable of indefinitely greater harmony and social homeostasis. This statement is not self-contradictory. True selfishness, if obedient to the other constraints of mammalian biology, is the key to a more nearly perfect social contract.”

“In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction.”

“Hope was an instinct only the reasoning human mind could kill. An animal never knew despair.”
