I wrote recently about several objections to the Kalam Cosmological Argument, but I wasn’t able to cover even the most common objections in one post. Here, I’ll examine a few more objections to the argument, as well as offer critiques and more links to read.
Matter can be neither created nor destroyed
A common objection to the Kalam Cosmological Argument (hereafter KCA or Kalam) is against its principles of causation. The atheist points out the principle of the conservation of energy: that energy can be neither created nor destroyed, but only change forms (it can equally be said that “matter can be neither created nor destroyed…”). Applying this to the Kalam, they argue that because the KCA asserts the universe began and was caused, it cannot be true–matter cannot come into existence.
There are several problems with this objection. First, it assumes a causal principle: that only material causes exist. For it is true that the conservation of energy applies to material causation, but it may not apply to immaterial causation. “Ah,” the atheist may counter, saying, “but why think that there is immaterial causation anyway?” Why? Because that’s exactly what the KCA is made to demonstrate: that the universe was caused by an immaterial entity. The first premise (Everything that begins has a cause) would indeed have to surrender to the conservation of energy… but only if it is assumed that the cause is material. The Kalam is presenting an immaterial cause, creating the universe ex nihilo–out of nothing. For more on this objection, see William Lane Craig’s answer to the question “Must everything have a material cause?”
Second, using the conservation of energy to argue against the beginning of the universe reveals confusion about cosmology to begin with. Scientists can extrapolate back to the beginning of the big bang–which is the moment when both space and time came into existence, along with all of the material world (Craig and Copan, cited below, 222ff). So we know scientifically that there was a moment when there was no matter at all. It was created, not out of other matter, but out of nothing. Here is the key to note: it is once the universe came into existence that the laws of nature came into effect–before the universe, there was nothing.
Third, if it is true that matter has never been created or destroyed, matter and energy would be eternal. But if that is the case, then due to another law of thermodynamics–entropy–the entire universe would have evened out all the energy by now. There would be no stars burning, no people breathing, etc. Thus, it is easy to see scientifically that the universe is not eternal.
Infinite Past is No Problem
The late atheistic philosopher J.L. Mackie objected to the Kalam from a different perspective. He felt that there was a problem with the way William Lane Craig tried to establish a finite past. He argues that “[The Kalam] assumes that, even if past time were infinite, there would still have been a starting-point of time, but one infinitely remote, so that an actual infinity would have had to be traversed to reach the present from there. But to take the hypothesis of infinity seriously would be to suppose that there was no starting-point…” (Mackie, 93, cited below).
William Lane Craig and Paul Copan point out that, “On the contrary, the beginningless character of the series of past events only serves to underscore the difficulty of its formation by successive addition. The fact that there is no beginning at all, not even an infinitely distant one, makes the problem worse, not better” (Craig and Copan, 214, cited below). It’s not that defenders of the Kalam argue that if the past is infinite, one could not count to the present–rather, it’s that if the past is literally infinite, there is no beginning, and one could never reach the present moment by successive addition.
If one finds this line of reasoning unconvincing, however, one must also deal with the empirical problem with an infinite past: entropy. If the universe has existed forever, then all the energy in the universe should have evened out by now. We would simply not observe the universe we do. Thus, both philosophically and scientifically, we can discount the idea of an infinite past.
The Multiverse, Redux
I addressed the multiverse in my previous post on the topic, but it should be noted how much of a difficulty there is for those wishing to use the multiverse to discredit the Kalam. Jeffrey Zweerink points out that according to Arvind Borde, Alexander Vilenkin, and Alan Guth, “any cosmos that expands on average (like an inflationary multiverse) must have a beginning in the finite past” (Zweerink, 32, cited below). The multiverse does not help those trying to avoid a beginning for the universe, it merely pushes the problem up one level.
Again, after subjecting the Kalam Cosmological Argument to multiple objections, it emerges unscathed. It establishes its conclusion: the universe has a cause. What does this mean? That’s a question we should all consider of utmost importance.
