Lewis continues his train of thought from “Men Without Chests”, criticizing the project of subjectivizing value. Lewis thinks the stakes are as grave as they can be: “the destruction of the society which accepts it”. But immediately, Lewis notes, such grave consequences do not make it false. And besides, there are “theoretical difficulties” as well. Those who advocate the subjectification of value, in this case the pseudonymous Gaius and Titius, presume some greater end even as they undercut traditional values. “In actual fact Gaius and Titius will be found to hold, with complete uncritical dogmatism, the whole system of values which happened to be in vogue among moderately educated young men of the professional classes during the period between the two wars. Their scepticism about values is on the surface: it is for use on other people’s values; about the values current in their own set they are not nearly sceptical enough.” But if Gaius and Titius have some ultimate ground for value in mind, which cannot be so debunked, what might that be? Lewis considers whether “instinct” can ground human value, but notes that instinct is itself contradictory and cannot warrant the leap from is to ought. One will be inexorably forced back to some objective law that presents itself to our conscience as self-evident and obligatory. “This thing which I have called for convenience the Tao, and which others may call Natural Law or Traditional Morality or the First Principles of Practical Reason or the First Platitudes, is not one among a series of possible systems of value. It is the sole source of all value judgements.” ~ Afterall
