Common Arguments, Refuted: the Cosmological Argument

Hello all,

This is the second in a series of posts deconstructing and refuting some common arguments in favor of theism, religion, faith, etc. This article will feature the so-called “cosmological argument.” The cosmological argument, also called the First Cause argument, goes way back. It was employed by both Plato (in Laws, book 10, his longest dialogue) & Aristotle, and by Thomas Aquinas. A version of this argument, the Kalam Cosmological Argument, is favored by theologian William Lane Craig.

The argument goes something like this:

  1. Whatever begins to exist has a cause.
  2. The Universe began to exist.
  3. Therefore, the Universe had a cause.

Put another way,

  1. Every finite and contingent being has a cause.
  2. A causal loop cannot exist.
  3. A causal chain cannot be of infinite length.
  4. Therefore, a First Cause (or something that is not an effect) must exist.

The current understanding of science holds that spacetime began to exist when the universe began to exist. It is meaningless to ask what came “before” the Big Bang, in the same sense that it is meaningless to ask what’s “south” of the South Pole. The concept of “before” didn’t logically exist “before” the existence of time itself, so we needn’t concern ourselves with what came “before” our universe. As Stephen Hawking famously said, “Anything that happened before the Big Bang could not affect what happened after.”

There are several reasons the cosmological argument doesn’t hold water. I think the easiest comes from the particle physicist Victor Stenger, who wrote the wonderful books God: The Failed Hypothesis and The Fallacy of Fine-Tuning: Why the Universe is Not Designed For Us. The error in reasoning can be summarized in five words 5 words: The first premise is false. According to Stenger, quantum physics tells us that something CAN come from nothing, so the entire idea that everything that begins to exist must have a cause is just plain wrong.

This premise is an example of a bare assertion, a statement unsupported by evidence. This is something for which, as skeptics, we need to watch out in general. If someone presents an assertion to you, especially as a basis for a set of premises, we need to take a moment to ask, “How do you know that?”

As with most of these arguments, this is really an argument for deism, or at best theism, not Christianity or any god or gods in particular. If you find yourself in a debate about Christianity or any particular religion or god, make sure to drive home this point: This is a (piss-poor) argument for deism—belief in a creator entity, whether still extant or not—not an argument for theism or any particular god. If someone tries to tell you that something can’t come from nothing, therefore Jesus, remind them that this is a non sequitur. It is no better than arguing “something can’t come from nothing, therefore Brahman,” or any other creator entity.

I’m reminded of the wonderful Sidney Harris cartoon, which I will not reproduce here for copyright reasons but which you can google if you’d like (try “Sidney Harris miracle math cartoon”): Two mathematicians are standing at a chalkboard with some complicated figures, and in the second of three deductive steps, it simply says, “Then a miracle occurs.” The one mathematician says to the other, “I think you should be more explicit here in Step Two.”

If someone cannot tell you how they know something, there’s a good bet that they’re bullshitting you. Sometimes the right answer is, “I don’t know, but very smart people are working on that.” For me, that sums up anything we could ever want to know about the “god question,” and it’s why I’m an agnostic atheist.

Until next time,

Dave
