Why is there anything, rather than nothing at all? This question often serves as a debating tactic used by theists to attack naturalism. Many people apparently regard the question—couched in such stark, general terms—as too profound for natural science to answer. It is unanswerable by science, I argue, not because it’s profound or because science is superficial but because the question, as it stands, is ill-posed and hence has no answer in the first place. In any form in which it (...) is well-posed, it has an answer that naturalism can in principle provide. The question therefore gives the foes of naturalism none of the ammunition that many on both sides of the debate think it does. (shrink)
