A History of Ideas [53min]

What's the big idea? Well, it turns out there are three of them...the soul, Europe and the experiment. Those are the three big ideas that Peter Watson uses to focus his history of ideas. In this hour of "To the Best of Our Knowledge," we'll talk about the history of ideas...from fire to Freud...including a language history of the world, shocking movies that changed history, and reinventions of the novel.
