Why do we like the things we like?

The Yale psychologist Paul Bloom is interested in big fundamental questions of an aesthetic or moral kind, such as: Why do we like certain things, but dislike others? Why do we consider that one thing is right, whereas another is wrong? In this entertaining 16-minute video, Bloom provides us with fascinating and often amusing cases of human likes and dislikes.

In the great debate of nature v. nurture, I'm pleased to discover that Paul Bloom is an opponent—like Steven Pinker—of the infamous "blank slate" theory [display]. He says: "A growing body of evidence suggests that humans do have a rudimentary moral sense from the very start of life."
