Man is shut up to relatively few answers. I think we often fail to understand that the deeper we go into study at this point, the simpler the alternatives become. In almost any profound question, the number of final possibilities is very few indeed. Here there are four: (1) Once there was absolutely nothing and now there is something, (2) Everything began with an impersonal something, (3) Everything began with a personal something, and (4) There is and always has been a dualism. —Francis Schaeffer, Genesis in Space and Time
