>>53 the matter in the universe is finite, yea, but the empty space in the universe is looking infinite to general relativity and string/quantum theory (especially if you take into account time, which is infinite, as the 4th dimension) and [at least most western] philosophy for that matter.
Regardless, Descartes description of god is very non-fundamentalist and if you want to draw conclusions from what he is saying you should look at the content and not the fact that he refers to the infinite as god.
