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.
C. S. LewisStrictly speaking, there are no such things as good and bad impulses. Think...of a piano. It has not got two kinds of notes on it, the 'right' notes and the 'wrong' ones. Every single note is right at one time and wrong at another. The Moral Law is not any one instinct or set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts.
C. S. LewisDeath and resurrection are what the story is about and had we but eyes to see it, this has been hinted on every page, met us, in some disguise, at every turn, and even been muttered in conversations between such minor characters (if they are minor characters) as the vegetables.
