Why We Cooperate Quotes

“For parents who think that their child must have skipped the naturally cooperative stage, let me quickly note that we are talking here about a behavior measured in relation to other primates. All viable organisms must have a selfish streak; they must be concerned about their own survival and well-being or they will not be leaving many offspring. Human cooperativeness and helpfulness are, as it were, laid on top of this self-interested foundation.”
― Michael Tomasello, Why We Cooperate
