An old conception of art is that it was supposed to be beautiful or represent something. What happened? Are there necessary and sufficient conditions for being art? Ken suggests that art might be a family resemblance concept, that is, lots of different art pieces resemble each other, but there is no underlying thread that connects them all. What makes an artistic process artistic? Ken introduces the guest, Alexander Nehamas, professor at Princeton. Nehamas points out that the first time that the question of what art is came up was in the 19th century in a pamphlet by Leo Tolstoy. Nehamas doubts that one can define art. Ken suggests that art is whatever is made in an artistic process and consumed as art. John counterrs that this is circular. Nehamas points out that most pieces of art in museums were not intended to be art. Nehamas thinks that to be an art object, that object must differ interestingly from others of its kind.
