Stephen Hawking, in his recent book entitled The Grand Design, states that philosophy is dead. Without going into the reasons behind his thinking, I'd like to know the response of current philosophers to Hawking's statement. He has laid down a gauntlet of sorts, a challenge to philosophers to make their work relevant to the recent advances and discoveries made by cosmologists, astrophysicists, and others on the cutting edge of scientific discovery and investigation. Are present-day philosophers up to Hawking's challenge?
Scientists who write obituaries for philosophy forget that science depends on philosophical assumptions. When some lab results or observations of the visible universe confirm or disconfirm a prediction in physics, Hawking and colleagues draw conclusions about the whole universe. But does any set of observations justify conclusions about unobserved cases? Is "elegance" an objective feature of a theory, and does it make a theory having it more likely to be true? And so on. Philosophers grapple with these questions; scientists just presume answers to them. Unless we ignore such questions, philosophizing is inescapable.
