Článek je zajímavý celý, ale úvodní pasáž se mi líbí natolik, že stojí za přímou citaci, byť přímo nesouvisí s hlavní pointou (zdůraznění moje):
Long ago our primate ancestors learned to be “political.” That is, instead of just acting independently, we learned to join into coalitions for mutual advantage, and to switch coalitions for private advantage. Our human ancestors added social norms, i.e., rules enforced by feelings of outrage in broad coalitions. (...)
In ancient politics, people learned to attract allies, to judge who else was reliable as an ally, to gossip about who was allied with who, and to help allies and hurt rivals. In particular we learned to say good things about allies and bad things about rivals, such as accusing rivals of violating key social norms, and praising allies for upholding them.
