My problem is right away; Book I. Lewis posits a law that he calls variously the Law of Human Nature, or Moral Law, or Rule of Decent Behavior. The idea is that there is a Law that all people feel. It tells us what is right, and what is wrong. This is why we know that, for example, we should not steal, and that we should keep our promises. He says this law is a fact, just as the law of gravity is a fact. But, while the law of gravity cannot be disregarded, the Moral Law can.
So far, I was impressed with how he explained what he had in mind. With one exception, I thought he was making very good points, and doing so logically and convincingly. He had good arguments against some things that I would have thrown at him. I was looking forward to hearing him do away with what I consider this Moral Law's true nature. I was getting upset that he seemed to be ignoring it entirely. But finally, in chapter 3, he says it:
So far, so good. Now I wanted to hear him explain why this was not the actual explanation for the Moral Law. He continues the same paragraph:Some people say that though decent conduct does not mean what pays each particular person at a particular moment, still, it means what pays the human race as a whole; and that consequently there is no mystery about it. Human beings, after all, have some sense; they see that you cannot have real safety or happiness except in a society where every one plays fair, and it is because they see this that they try to behave decently. Now, of course, it is perfectly true that safety and happiness can only come from individuals, classes, and nations being honest and fair and kind to each other. It is one of the most important truths in the world.
The key is in the first sentences of each quote:But as an explanation of why we feel as we do about Right and Wrong it just misses the point. If we ask: "Why ought I to be unselfish?" and you reply "Because it is good for society," we may then ask, "Why should I care what's good for society except when it happens to pay me personally?" and then you will have to say, "Because you ought to be unselfish" - which simply brings us back to where we started. You are saying what is true, but you are not getting any further. If a man asked what was the point of playing football, it would not be much good saying "in order to score goals," for trying to score goals is the game itself, not the reason for the game, and you would really only be saying that football was football - which is true, but not worth saying. In the same way, if a man asks what is the point of behaving decently, it is no good replying, "in order to benefit society," for trying to benefit society, in other words being unselfish (for "society" after all only means "other people"), is one of the things decent behaviour consists in; all you are really saying is that decent behaviour is decent behaviour. You would have said just as much if you had stopped at the statement, "Men ought to be unselfish."
...it means what pays the human race as a whole...
Many people do not "feel as we do about Right and Wrong," and do not care about the human race as a whole.But as an explanation of why we feel as we do about Right and Wrong...
The thing is, he's been trying to establish that there's this Law that all people feel, despite the fact that we don't always follow it. He wrote this in the 1940's, so the Nazis were big on his mind. He says that even they felt this Moral Law, but chose to ignore it, for whatever reasons. But I see no reason to believe that. I believe the Nazis - as well as many, many, many other societies and individuals - felt and feel otherwise. I do not say that nobody feels that cheating is bad, and keeping your word is good. I feel that way, and I know that many of you do, too. But that is not proof that everybody else does.
Many individuals do what benefits them individually, without any regard for the principles of Lewis' Moral Law. The question is, why would they lie about it when caught? Some lie about it because they want to be trusted in the future. After all, it's much easier to cheat people who trust you. Some lie to keep out of jail. Still others see that it would be difficult to live safely and happily if society was in anarchy, and they lie so everybody else stays on the straight and narrow. (And yes, some do believe they did something wrong. But they tried the easy/quick way this time. And some of them lie about it because they don't want to be embarrassed.)
There are effecient ways to run the world besides the one where everybody benefits by everyone playing fair. As long as I (or a select group of friends) benefit, what do I care about the rest? When people who think like that get together, all Hell breaks loose. The Nazis are a good example. I can get what I want if I kill anyone who tells me I can't have it. In the early days of my country, the US government killed most of the Native Americans, and stole the land from those left alive. They got what they wanted NOT by following any Moral Law, but by eliminating those they would have had to share with. History is filled with groups that have lived by this law. I do not suspect many of them had any trouble sleeping at night.
Lewis never addresses this possibility. He says everyone feels this Moral Law.
