After a mild indoctrination into the Christian faith, at the age of 15 I discovered myself to be a non-believer: the idea of an invisible, omniscient, omnipotent, omnipresent God suddenly seemed simply unbelievable. Years later I decided to re-examine the question. Perhaps I had missed something. This in turn led to a fascination with God questions and religious belief, but a re-confirmation of my earlier discovery: the traditional Christian concept of God was not only unbelievable, but incoherent and morally muddled. But further reflection has yielded a qualifying conclusion: God—or rather gods, many gods—do exist but as ideas, tremendously powerful ideas that shape our reality. The crucial concern is that these be good ideas, which has not always been the case.
