Kids' Questions and Adults' Questions
Yesterday, Mark at Minute Particulars commented on the sorts of questions materialists and atheists ask, e.g. "Does God exist?" or "Is there such a thing as a soul?". Mark proposes that such questions are usually sorted out by people as children, but that -- for some reason -- atheists and materialists never did so. He goes on to (rightly) point out that assertions like "God does not exist" are ultimately non-sensical and irrational, because to assert them implies that there is no necessary existant, which is rationally impossible.
He makes some other thought-provoking comments, but rather than trying to summarize them, let me recommend that you simply go read the post. As always, Mark has solid stuff to say.
