XFiles Weekend: Toxic faith
September 19, 2010 — Deacon Duncan(Book: Mere Christianity by C. S. Lewis, chapter 4, “What Lies Behind the Law”)
We come now to Chapter 4 of Mere Christianity, and I’m going to steal a little of Lewis’ thunder by giving away the plot. As we’ve seen in the first three chapters, Lewis wants to claim that there exists some sort of “real” Moral Law which he can then attribute to an invisible, magical Being, or Lawgiver. Trouble is, if we take any sort of rational and objective look at the actual evidence, we find that it’s fundamentally inconsistent with his claims. Instead of admitting that the facts don’t fit, however, Lewis argues that this glaring discrepancy is proof that multiple realities exist, and that his so-called Moral Law must come from the other one.
In making this argument, Lewis has implicitly thrown reason and science out the window, but in Chapter 4 he goes on to make this more explicit. Appealing to the age-old expedient of declaring that this new “truth” lies beyond the reach of science, he declares that we must reject and ignore any sort of reasonable, scientific evaluation of the “evidence” he tries to use to back up his claims. The problem with abandoning science and reason, though, is that it becomes very difficult to make a coherent argument without them, as Lewis is about to demonstrate.
