Yesterday, I began reading Mere Christianity by C.S. Lewis for the CHOOSE CT High School Book Club. I am only one or two chapters along, but already I found this thought-provoking idea:
Progress means not just changing, but changing for the better. If no set of moral ideas were truer or better than any other, there would be no sense in preferring civilised morality to savage morality...In fact, of course, we all do believe that some moralities are better than others.
- snip –
The moment you say that one set of moral ideas can be better than another, you are, in fact, measuring them both by a standard, saying that one of them conforms to that standard more nearly than the other. But the standard that measures two things is something different from either. You are, in fact, comparing them both with some Real Morality, admitting that there is such a thing as a real Right, independent of what people think, and that some people’s ideas get nearer to that real Right than others.
