(Laughter) The fourth explanation is captured in the title of a book called "The Expanding Circle," by the philosopher Peter Singer, who argues that evolution bequeathed humans with a sense of empathy, an ability to treat other peoples' interests as comparable to one's own. Unfortunately, by default we apply it only to a very narrow circle of friends and family.
(Naer) Neljas seletus seisneb ühe raamatu pealkirjas nimega "Laienev Ring", mille autor on filosoof Peter Singer, kes väidab, et evolutsioon on kinkinud inimestele empaatiavõime: võime kohelda teiste inimeste huvisid enda huvidega sarnaselt. Kahjuks, tavaliselt kasutame me empaatiat ainult sõprade ja pere kitsas ringis.
