Guest: Jim Holt.

Author Jim Holt is not satisfied with the regular responses to the question "Why are we here?" There are many more possible answers, says Holt, than the old God versus the Big Bang debate would suggest. This hour on Focus, we'll listen back to a conversation with Holt about his new book Why Does the World Exist? He'll talk about his correspondence with philosophers, physicists, and a Buddhist monk in his quest for big answers.
