We are here debating the Kalam Cosmological Argument from a deistic rather than theistic perspective. Carlo Alvaro is taking the affirmative; Richard Carrier the negative. See our initial entry for all the details, including an index to all entries yet published.

Dr. Carrier contends that my argument has two problems:

  1. The premises are false because they are “contrary to established science.” 
  2. The argument does not prove “anything describable as a god.”

It is not possible to prove the truth of the premises with 100% certainty. The best I can do is to demonstrate that they are more likely true than false. Therefore, I was surprised when Dr. Carrier declared that my premises are 100% false. But why does he claim that they are false? Because he thinks that they are contrary to science. Again, I was surprised to hear this because science has zero evidence that any object (whether material or immaterial) can come, or ever came, into existence without a material or an efficient cause. 

I. Premise 1

Premise 1 is consistent with science. Every object that begins to exist that humans always have experienced, and scientists routinely study, come into existence by something else. Every amoeba, every chair, every stone, every baby, and every quark came into existence by something else. Thus, when Dr. Carrier says that science has not established the truth of premise 1, he must mean something different. 

Dr. Carrier means something like this: Because scientists have not yet discovered any object that comes into being by nothing, then we cannot rule out such a possibility. But then it does not follow from this that the the first premise of the Kalam is false. At best, it shows some doubt that it is 100% true. 

Consider the evolution of life. Is it logically possible that a god created everything and made it look like evolution occurred? Sure. But just because creationism is logically possible, it does not follow that evolution is false. Therefore, Dr. Carrier is entitled to raising doubt to the truth of premise 1 but not entitled to the conclusion that it is 100% false for the reason that science has not yet ruled out the possibility that objects can spontaneously come into being by nothing. 

The way Dr. Carrier presents his argument is fallacious. He writes that my premise 1,

…is not logically necessarily true, and therefore must necessarily be only contingently true.

But then, from these premises he jumps to an unsupported conclusion. He writes, 

But if it is only contingently true, it is logically possible for there to be states of affairs not subject to it. It is therefore logically impossible that ‘all’ things that begin to exist must come into existence by something else. Premise 1 is therefore logically impossible and therefore false.

If premise 1 is, as he asserts, merely “contingently true”, it does not follow at all that it is “impossible” that at least one object comes into existence by something else. For those who studied categorical logic, A-form and E-form are contraries, i.e., they cannot both be true, but they may both be false. For example, if some judges are lawyers, then the universal affirmative A (All J are L) is false and so is the universal negative E (No J are L). In other words, the falsity of “All things that begin to exist came into being by something else” does not logically entail the truth of  “No thing that begins to exist came into existence by something else.” Consequently, his conclusion, 

Premise 1 is therefore logically impossible and therefore false.

does not follow at all. 

Second, we must be careful with the word “possibility.” In logic, we distinguish between “strict” and “broad” logical possibility. For example, it is logically possible that I throw a baseball to the moon (there is no inherent logical contradiction), but it is not physically possible. Therefore, strict logical possibility does not logically entail metaphysical possibility. Thus, the strict logical possibility that an object comes into existence by nothing does not prove that such an event is metaphysically possible. As I tried to demonstrate, the first premise of the Kalam is a metaphysically necessary truth.

II. Premise 2

Now premise 2. Dr. Carrier claims that the big bang theory does not prove that time, space, and energy came into being a finite time ago. But this is exactly what the theory says. In fact, physicists always correct us when we say things like, “Before the big bang…” because spacetime did not exist without (not prior to) the universe. So, you can cook up some creative model, such as a multiverse or a time-mirror or a quantum gobbledygook, but those aren’t arguments but mere speculations.

Dr. Carrier writes, “the state of affairs of there being nothing that is as yet caused to exist…” The definition of nothing is “not anything.” If I said to you “Nothing beats a glass of Italian wine” and you replied to me, “Then, I want some nothing!” you would commit what logicians call the existential fallacy. In short, “nothing” is not a state but rather the absence of time, space, matter, energy, potentiality, and so on. And from nothing, nothing comes.

Concerning Dr. Carrier’s second contention, “None of this gets to anything describable as a god.” The Kalam is not meant to say anything about a god. In fact, nowhere in the syllogism does the word “god” occur.

Regarding an alleged, “unstated ‘Premise 4”, there is no unstated premise 4. The Kalam has only 2 premises. My belief that a god exists is based on an analysis of the conclusion (which I will address that in my next entry because I am running out of space).

The last point is the notion of actual infinity. Dr. Carrier writes “Even your fingernail consists of an actual infinity of geometric points.” And how does he know this? In set theory, an actually infinite set contains a discrete number of members. Conversely, no physical object can contain, or can be divided into, an actually infinite number of parts. 

Regarding the stairs example, I never claimed that the present is “the end of all time.” The point is that the present time exists. But if the universe were past-eternal, then it would be impossible for the present to be instantiated because it is impossible to traverse an actually infinite number of events. 

III. Conclusion

As a concluding remark, I want to emphasize that, unlike a theist, I did not start from the belief in God and then tried to find an argument that proves God’s existence. Rather, I started from no belief whatsoever and found that the Kalam is a powerful argument that points in the direction of a god. Thus, I will be glad if Dr. Carrier, or anyone else, could show me that the Kalam is unsound because I have nothing to lose. Regrettably, however, Dr. Carrier’s first reply was a sincere but unsuccessful attempt. Thus, I remain convinced the Kalam is more likely sound than not and, therefore, that a god brought the universe into existence.
