C.S. Lewis once said: First, human beings, all over the earth, have this curious idea that they ought to behave in a certain way, and cannot really get rid of it. Secondly, that they do not in fact behave in that way. They know the Law of Nature; they break it.

The term 'Law of Nature' refers to the fact that it is part of our human nature and is therefore something we all know by virtue of just being human. Lewis believed that we know right from wrong, and still defy it.

Where do you think the notion of knowing right from wrong comes from?
Yes, behaviour that benefits a whole group plays a huge part.
