This groundbreaking volume investigates the most fundamental question of all: Why is there something rather than nothing? The question is explored from diverse and radical perspectives: religious, naturalistic, platonistic and skeptical. Does science answer the question? Or does theology? Does everything need an explanation? Or can there be brute, inexplicable facts? Could there have been nothing whatsoever? Or is there any being that could not have failed to exist? Is the question meaningful after all? The volume advances cutting-edge debates in metaphysics, philosophy of cosmology and philosophy of religion, and will intrigue and challenge readers interested in any of these subjects.
