Last May, Stephen Hawking gave a talk at Google's Zeitgeist Conference in which he declared philosophy to be dead. In his book The Grand Design, Hawking went even further. "How can we understand the world in which we find ourselves? How does the universe behave? What is the nature of reality? Where did all this come from? Traditionally these were questions for philosophy, but philosophy is dead," Hawking wrote. "Philosophy has not kept up with modern developments in science, particularly physics."
