XFiles Weekend: Assumptions and consequences
August 1, 2010 — Deacon Duncan(Book: Mere Christianity by C. S. Lewis, chapter 1, “The Law of Human Nature”)
Chapter 1 of Mere Christianity sets out to establish what C. S. Lewis calls “two facts” that “are the foundation of all clear thinking about ourselves and the universe we live in.” We looked at the first of these “facts” last week: the notion that there is some kind of universal Moral Law, aka the Law of (Human) Nature, that dictates the definition of Right and Wrong. According to Lewis, we all know that this Moral Law exists, and we’ve even got some kind of inherent knowledge of what its commandments are. And yet (“fact” number two), we do not do what this Law tells us we should.
We’ll get to the rest of Chapter 1 in a moment, but first let’s note in passing just how far Lewis has already gone astray, due to the preconceived ideas he’s trying to impose on his interpretation of the evidence. Because he’s thinking in terms of divine commandments, he’s already introducing the notion that his so-called Moral Law is not just a description of common patterns of behavior, but is in fact some kind of obligation that each and every individual is somehow responsible to live up to. It’s a subtle little twist, but as he gets into the second part of Chapter 1, we’ll see that this extra little assumption is really a key factor intended to drive us to Lewis’ desired conclusion.
It’s kind of slick, in a way. He directs our attention to certain real-world facts (i.e. the way people judge actions in light of consequences), and then, while our attention is focused on the observations, he slips in a subtle, biased twist that colors our interpretation of these facts. Notice, the extra twist is not part of the observed facts: we don’t observe any Universal Moral Law with any objectively declared principle binding its precepts upon all mankind. This is purely Lewis’ ideology, injecting itself into the argument when it thinks no one is looking. Pretty sneaky, eh?
