Is Chance a Cause?

I was recently reading the book An Atheist Defends Religion: Why Humanity Is Better Off With Religion Than Without It, by author Bruce Sheiman. In this book, he gives a general outline from atheism as to how we came to the place of human life.

Human Life = Laws of physics X chance + randomness+ accidents+ luck X 3.5 billion yrs. The laws of physics for our present universe arose by chance (from a multitude of possible universes); the first forms of life developed by chance (arising by primordial soup combinations that resulted from the laws of physics plus accidents); the first concept of life developed purely by chance (genetic mutations and environmental randomness); and humans evolved by more improbable occurrences.

It is common for skeptics like Richard Dawkins to appeal to “chance” in the history of life scenarios. This is very problematic and here’s why: Generally speaking, two usages are commonly confused when speaking about chance: It can viewed as a mathematical probability or as a real cause. To view chance as having some sort of causal power is very problematic. Let me explain:

If I roll a dice the chances are one in six that the number six will come out on top. The odds are one in thirty-six that two dice will both come up six and one in 216 that three sixes will be thrown on three dice. These are abstract mathematical probabilities. But it is not chance that caused those three dice to turn up sixes. Instead, it was the force of throwing them, their starting position in the hand, the angle of the toss, how they deflected off objects in their way, and other results of inertia. Chance had nothing to do with it. R.C. Sproul gives us a few things to ponder:

1. Chance is not an entity
2. Nonentities have no power because they have no being
3. To say that something happens or is caused by chance is to suggest attributing instrumental power to nothing. (1)

In the end, I think it is imperative to define the word “chance” in these discussions. The theist is often accused of the “God of the gaps” fallacy. But in the end, skeptics don’t fair much better with the “chance of the gaps” fallacy. A final quote will do:

“Scientists rightly resist invoking the supernatural in scientific explanations for fear of committing a god-of-the-gaps fallacy (the fallacy of using God as a stop-gap for ignorance). Yet without some restriction on the use of chance, scientists are in danger of committing a logically equivalent fallacy-one we may call the ‘chance-of-the-gaps fallacy.’ Chance, like God, can become a stop-gap for ignorance.”

—William Dembski
