Why are original paintings so much more valuable than forgeries? Why do people pay
millions for abstract art? How do creations such as Duchamp's urinal get to be artwork
in the first place? I present evidence that our understanding and appreciation of art
- even contemporary art -- reflects universal aspects of human nature. I argue that
the experience of art is not special: there are deep parallels between the pleasures we get from
artwork and the pleasures we get from seemingly simpler activities such as food and sex.
