The Kalam Cosmological Argument

by J.W. Wartick

One of the most frequently cited and debated arguments for the existence of God is the Kalam Cosmological Argument. I have not written on the argument before because there is simply so much good material on it out there that I don’t think I can add anything new. I have, however, run into numerous people with questions on the argument recently, and felt the need to finally get around to a post on the Kalam. Those interested in the argument are highly encouraged to read the links included at the end.

The argument

The argument itself is quite simple:

1) Everything that began to exist has a cause

2) The universe began to exist

3) Therefore, the universe has a cause

The argument is deductively valid, so the question is whether the premises are true. If true, the conclusion is certain.

Defense of Premise 1

Why should we think that whatever began to exist has a cause? First, it seems a denial of this principle would undermine science. Science is an investigation of causation. If the anti-theist wishes to deny this premise, she is committed to a fallacy similar to that which she calls the “goddidit” fallacy: dismissing explanation for an event. (Interestingly, saying “God did it” is not a dismissal of explanation: it is, itself, an explanation. It’s saying the explanation which best fits the evidence is theism.)

Suppose premise 1 were false. In that case, things could and would be coming into existence for no reason whatsoever out of nothing. We would observe a remarkably different universe than that which we do, in fact, observe. A tiger would miraculously materialize in my room and eat me.

Now, it must be noted that some appeal to quantum physics in order to say this premise is false. They hold that certain quantum events bring things into existence without reason. Such an interpretation seems misguided at best, however, for a few reasons. First, the event would seem to have an explanation, namely, that it is a quantum phenomena of type x. Second, even were one to deny that this is a form of explanation or causation, the fact remains that these quantum events don’t originate from nothing. They originate from the laws and systems present within our universe. Third, these quantum events, on an examination of quantum theory, are not uncaused; they are merely spheres of probability. Finally, an exclusion of causal chains seems to undermine quantum theory itself or at least make it difficult to correctly interpret (on this, see William Wharton’s paper “Causation with Quantum Mechanics”). Like Wharton, I think the main reason causation is sometimes excluded from interpretations of QM is because of an avoidance of “metaphysical first causes.” Obviously, if this is the motivation for avoiding causation, it is not spurred by a commitment to science, but a commitment to avoiding the metaphysical implications of science…
