(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.
(Smiekli) Ceturto iemeslu lasām filosofa Pītera Singera grāmatas nosaukumā "The Expanding Circle". Viņš uzskata, ka evolūcija apveltīja cilvēkus ar iejūtību: spēju izturēties pret citu cilvēku interesēm līdzīgi kā pret savējām. Diemžēl parasti mēs to pielietojam tikai šaurā draugu un ģimenes lokā.
