More on the upcoming Carroll vs. Craig dialogue (previously, one, two, three). I have some leftover business from my previous post on the contingency argument for the existence of God. It concerns the question why is there something something rather than nothing?, a question I’ve discussed on a few previous occasions.
The question “why is there something something rather than nothing?” is not an argument, obviously. It’s a question. It’s relationship to the cosmological argument for the existence for God is as an entree, a taster. It’s supposed to get you thinking about existence.
Imagine two parties. At one is everything that actually exists (or has existed) – the “actual” party. At the other, everything that could exist – the “possible” party. Horses are at both parties, unicorns only the possible party. Why? Because of something at the actual party, in this case the evolutionary ancestors of the horse. When something moves from possible to actual, it’s because of an invitation from the actual party. Those in the possible party can’t crash the actual party. They don’t exist, and so don’t have any causal powers, so can’t make anything actually happen.
So this actual party – did everyone get their invitation off someone else? Is there an infinite regress of inviters? It can’t form a loop – I invite you and you invite me – because that’s just crashing the party. Could there be a party where everyone must be invited by someone who’s already there? Why is anyone at the party? Why does anything exist?
Not the Question
Aside: The question is not: “something came from nothing. How could that happen?”, to which the answer is supposedly: because God can make something out of nothing. That confuses the contingency argument with the Kalam argument. The question is “Why is there something rather than nothing?”. The answer is: God is a necessary being, so it is not possible for there to be nothing. God must exist.
Carroll discusses the question “why is there something rather than nothing?” in this blog post. Amongst other things, he discusses the claim that “nothingness is uniquely natural”, so that we need some special reason why something exists. He argues that we have no basis for such a conclusion, as our intuitions for naturalness and simplicity are based on our experience in this world, and so don’t automatically apply to the universe itself.
However, most versions of the cosmological argument don’t explicitly appeal to the naturalness of nothing. Carroll, following Grunbaum, discusses Swinburne. In Grunbaum’s paper “Why is There a World AT ALL, Rather Than Just Nothing?”, he quotes Swinburne: “It remains to me, as to so many who have thought about the matter, a source of extreme puzzlement that there should exist anything at all” (pg. 336). I think, however, they’ve missed the point of what Swinburne is saying. (I say this with some trepidation. Grunbaum is a professional philosopher, and something of a legend. Fools rush in …) (more…)
