Why does the world exist? Why is there something rather than nothing? It is a non-trivial fact that people have been fascinated by such questions for thousands of years. Some theists believe that they have the answer: God. Randal Rauser, in the post that I began examining in my most recent post, says this:

And so for the person who wonders “But why should anything exist at all?” the answer comes: “Because the omnipotent, necessarily existent God brought it into being.”

Is this a satisfactory answer? If God does exist, is he the ultimate explanation for why there is something rather than nothing? At first glance, it seems obvious that this cannot be the answer. The theist’s answer presupposes the existence of something, God, and thus can hardly be taken as an explanation for why there exists anything whatsoever. If we are curious about the whys and wherefores of the universe, don’t we have to ask our why questions about every existing being? Doesn’t even the theist have to ask why there is a God (rather than no God)?

Rauser thinks that this reaction and the accompanying demand for an explanation for the existence of God involves a significant misunderstanding about the nature of God. God, says Rauser, is the terminus of explanation, he is the prime mover, the uncaused cause. God exists necessarily and so there is no question of explaining his existence; God just is. Here is Rauser explaining that some things just exist and need no explanation for their existence:

we should note that not all our intuitions about things are weighted toward asking “why”. In other cases our first intuition (at least the first intuition of philosophers who have thought long and hard about the relevant issues) is to reject the very appropriateness of the why question. The reason? Because it seems that some things just are.

Examples? Here’s a simple one. Think about the number “5″. What is this thing that was the object of the previous sentence? What were you thinking about when you thought about the number 5? The realist proposes that you are thinking of an abstract object or, to use a more traditional term, a universal. That is, 5 is a non-physical, atemporal object that can be multiply exemplified in concrete things (such as the conventional inscription “5″ on the chalk board). But it is itself distinct from all those concrete exemplifications.

Whether Rauser is correct about numbers is a topic for a different discussion. The point here is that he thinks that God exists necessarily in a way analogous to the existence of numbers. Just as numbers could not but exist, so too, God cannot but exist. But how does Rauser know this? How could we know that the creator of our universe, the inspiration for the Bible, the father of Jesus, is Himself uncaused? That he exists necessarily? That he just is? Rauser’s answer is that it is part of the very definition of ‘God’:

You see, theologians define God as existing a se, that is existing of and in himself and not drawing his life from anything else. Put another way, they have always understood him to have the property of independence or necessity, and thus to be the unmoved mover or first cause.

God exists necessarily. And, importantly, Rauser says that there is no need to argue for this conclusion and no question of providing evidence for it because God is a necessarily existence causal agent by definition.

In my previous post I tried to cast some suspicion on the concept of aseity and I also argued that the fact that a being exists a se does not imply that there is not a fuller explanation of its existence. Now I want to consider a different issue: Is it true that it is part of the concept of God that he exists a se?

I think that it is possible that there is a such a conception of God according to which it is just part of the concept that he exists of his own nature. However, I don’t think that this is the concept that most theists use. And, despite that fact that I am sure that he would vehemently protest, I am skeptical of the claim that this is the conception of God that Randal Rauser uses. Here is why:

If it is part of the concept of God that he exists of his own nature, then, if there is nothing that exists of its own nature, then nothing answers to the concept ‘God’ and hence God does not exist. Assume, then, that tomorrow scientists announce the discover of an omnipotent, omninbenevolent, omniscient, creator who sent his only begotten son to die for the forgiveness of since but that he does not exist of his own nature. I highly doubt that, in such an unlikely eventuality, Rauser would announce that he was wrong and that atheism has been vindicated.

Of course scientists are never going to announce such a discovery, but the point stands. By committing himself to the claim that God exists a se by definition, Rauser is committing himself to rejecting theism if it turns out that there is no being that exists a se. If Rauser is right about the meaning of ‘God’, then even if there exists a creator of the universe who inspired the Bible and sent his son Jesus to be crucified for the forgiveness of sins, if this creator does not exist a se, then he is not God (and, by the way, people who believe in such a being are, if Rauser is correct, atheists since they don’t believe in God). But, again, a world in which such a being exists is not a world in which atheism is true. Since I don’t think that Rauser would say that a world in which such a creator exists is a world without God, I find it hard to take seriously Rasuer’s claim that God is, by definition, a being that exists of his own nature.

Theists often want to build a lot of content into their conception of God. Rauser thinks that by building aseity into the concept of God, the theist is relieved of the responsibility of explaining God’s existence. But I think that this is a bit of a lazy way out of a really interesting problem: the problem of why there is something rather than nothing. Maybe there is a self-existent being and maybe there is not, maybe a self existent being created the universe, maybe the creator of the universe was himself created  by some other being (maybe even a self-existent one), maybe a self-existent being sent his only son to die on Earth, or maybe a created being did, or maybe nobody did. Maybe the concept of self-existence makes sense and maybe it does not. But we don’t get to go around saying that we know that there is a self-existent being, that we know why there exists something rather than nothing, just because we have a concept with the very notion of existence built into it.
