If no set of moral ideas were truer or better than any other, there would be no sense in preferring civilized morality to savage morality, or Christian morality to Nazi morality. In fact, of course, we all do believe that some moralities are better than others . . . . 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 . . . 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."
