“What enables us alone, of all the animals, to cooperate in such a way? [W]e can cooperate flexibly with countless numbers of strangers, because we alone, of all the animals on the planet, can create and believe fictions, fictional stories. And as long as everybody believes in the same fiction, everybody obeys and follows the same rules, the same norms, the same values.”

— Yuval Noah Harari, What explains the rise of humans? (TEDGlobalLondon, 2015)
