We teach it to our children. We hear it on television and in storybooks. Now, the original title of this session was, "Everything You Know Is Wrong," and I'm going to present evidence that this particular part of our common understanding is wrong, that, in fact, our ancestors were far more violent than we are, that violence has been in decline for long stretches of time, and that today we are probably living in the most peaceful time in our species' existence.
Me õpetame seda oma lastele; me kuuleme seda televiisorist ja juturaamatutest. Selle osa algne pealkiri oli "Kõik, mida sa tead, on vale", ja ma esitan teile tõendeid, et see konkreetne osa meie ühistest arusaamadest on väär: et tegelikult olid meie eellased palju vägivaldsemad kui meie, et vägivald on pikkade perioodide vältel langenud, ja et täna elame me tõenäoliselt kõige rahulikumal ajajärgul meie liigi eksistentsi jooksul.
