(Book: Mere Christianity by C. S. Lewis, chapter 2, “Some Objections”)
In Chapter 1, C. S. Lewis introduced two ideas that (he claims) “are the foundation of all clear thinking about ourselves and the universe we live in.” These two ideas are (a) that there is a universal Moral Law defining right and wrong, which we somehow inherently know, and (b) that we do not obey this law. Unfortunately, these two ideas are not themselves the product of clear thinking, and indeed are a rather biased and superstitious failure to understand human morals realistically. There is no singular universal Moral Law by which we all make moral judgments; rather, we judge right and wrong based on how we feel about the outcome. This fundamental disconnect between theory and reality has already bubbled to the surface in a number of inconsistencies between what Lewis claims and what we find through even a trivial examination of the real-world facts.
In Chapter 2, Lewis acknowledges some of these difficulties and attempts to either refute or discredit them. As we shall see, though, his attempts to reduce his troubles only adds to them. As the good fairy told Pinocchio, once you tell a lie, it grows and grows until it’s as plain as the nose on your face—even when you sincerely believe the lie because you first deceived yourself.
