A New Defense of the Kalam

The Kalam Cosmological Argument (or KCA) is an argument for God from the beginning of the universe. After years of thinking through it and the objections, I’ve come to think it a pretty decent argument. I think both premises are likely true, and so the conclusion is true as well. Before giving a new defense of the Kalam, let’s take a look at a contemporary formulation of the argument:

(1) If the universe began to exist, it has a cause.
(2) The universe began to exist.
(3) The universe has a cause.

This argument is aptly defended by Christian philosopher and theologian William Lane Craig. He gives three arguments in support of (1), and another three in support of (2). He then gives a conceptual analysis of the cause of the universe and concludes that this cause is God (or something very close to God).

What I want to do here is give a new defense of the Kalam’s first premise.

A New Defense

The basic idea is this. Imagine a world where God exists, yet doesn’t decide to create anything. All that exists in this world is God. There are no planets, no galaxies, no humans, just God. Call this God-world.

Now we want to ask, what is the probability that a universe like ours would spring into existence uncaused in God-world? It’s intuitively obvious that this scenario is highly improbable, if not impossible. Any universe that comes into being in God-world would be caused by God. Duh. God would bring it into existence.

Taking God out of God-world doesn’t make this event any more or less likely. On this hypothetical scenario, the universe isn’t caused to exist by God. It has the property “not being caused by God” which is the same property it would have on Naturalism (or any other -ism). Thus, the probability of it coming into being uncaused is very low regardless of what else exists (or doesn’t exist).

Objection 1

Someone might say: Wrapped up in the concept of God is that He is the creator of anything that exists outside of Himself. So this scenario is impossible on Theism but not impossible on Naturalism.

An easy way around this is to alter the thought experiment to be about Clark-world instead of God-world. Clark is a super powerful being that can bring universes about. He is spaceless, timeless, immensely powerful, and personal. The same defense goes through on Clark-world.

Objection 2

Another objection might be: You’re appealing to intuitions and not everyone shares those intuitions.

First, I agree, but nothing of interest follows. Not everyone shares the intuition that other minds exist. Not everyone shares the intuition that the external world is real. Nothing follows from the fact that some intuition isn’t universal among humans. It could still be the right intuition. Second, appealing to commonly held intuitions still constitutes a defense.

Conclusive?

Does this new defense of the Kalam conclusively show that (1) is true? No. It’s unreasonable to expect such a thing. What it does is show that (1) is intuitively probable. It’s nonsensical to think there is a world where God exists alongside a finite universe uncaused by God. If anything, this scenario is incredibly unlikely. But if this is intuitively unlikely on Theism, it’s equally unlikely on every hypothesis (as argued above), and so (1) is probably true.
