The Law of Human Nature
C.S. Lewis
Mere Christianity, pp. 17-39

Every one has heard people quarreling. Sometimes it sounds funny and sometimes it sounds merely unpleasant; but however it sounds, I believe we can learn something very important from listening to the kinds of things they say. They say things like this: "How would you like it if anyone did the same to you?" – "That's my seat, I was there first" – "Leave him alone, he isn't doing any harm" – "Why should you shove in first?" – "Give me a bit of your orange, I gave you a bit of mine" – "Come on, you promised." People say things like that every day, educated people as well as uneducated, and children as well as grown-ups.

Now what interests me about all these remarks is that the man who makes them is not merely saying that the other man's behavior does not happen to please him. He is appealing to some kind of standard of behavior which he expects the other man to know about. And the other man very seldom replies: "To hell with your standard." Nearly always he tries to make out that what he has been doing does not really go against the standard, or that if it does there is some special excuse. He pretends there is some special reason in this particular case why the person who took the seat first should not keep it, or that things were quite different when he was given the bit of orange, or that something has turned up which lets him off keeping his promise. It looks, in fact, very much as if both parties had in mind some kind of Law or Rule of fair play or decent behavior or morality or whatever you like to call it, about which they really agreed. And they have. If they had not, they might, of course, fight like animals, but they cannot quarrel in the human sense of the word. Quarreling means trying to show that the other man is in the wrong. And there would be no sense in trying to do that unless you and he had some sort of agreement as to what Right and Wrong are; just as they would be no sense in saying that a footballer had committed a foul unless there was some agreement about the rules of football.

Now this Law or Rule about Right and Wrong used to be called the Law of Nature. Nowadays, when we talk of the "laws of nature" we usually mean things like gravitation, or heredity, or the laws of chemistry. But when the older thinkers called the Law of Right and Wrong "the Law of Nature," they really meant the Law of Human nature. The idea was that, just as all bodies are governed by the law of gravitation and organisms by biological laws, so the creature called man also had his law—with this great difference, that a body could not choose whether it obeyed the law of gravitation or not but a man could choose either to obey the Law of Human Nature or to disobey it.

We may put this in another way. Each man is at every moment subjected to several sets of law but there is only one of these which he is free to disobey. As a body, he is subjected to gravitation and cannot disobey it; if you leave him on supported in mid-air, he has no more choice about falling than a stone has. As an organism, he is subjected to various biological laws which he cannot disobey any more than animal can. That is, he cannot disobey those laws which he shares with other things; but the law which is peculiar to his human nature, the law he does not share with animals or vegetables or inorganic things, is the one he can disobey if he chooses.

This law was called the Law of Nature because people thought that everyone knew it by nature and did not need to be taught it. They did not mean, of course, that you might not find an odd individual here or there who did not know it, just as you find a few people who are colorblind or who have no ear for a tune. But taking the race as a whole, they thought that the human idea of decent behavior was obvious to everyone. And I believe they were right. If they were not, then all the things we said about the war were nonsense. What was the sense saying the enemy were in the wrong unless Right is a real thing which the Nazis at bottom knew as well as we did and ought to have practiced? If they had no notion of what we mean by right, then, though we might still have had to fight them, we could no more have blamed them for that than for the color of their hair.

I know that some people say the idea of a law of nature or decent behavior known to all men is unsound, because different civilizations in different ages have had quite different moralities.

But this is not true. There have been differences between their moralities, but these have never amounted to anything like a total difference. If anyone will take the trouble to compare the moral teaching of, say, the ancient Egyptians, Babylonians, Hindus, Chinese, Greeks and Romans, what will really strike him will be how very like they are to each other and to our own. Some of the evidence for this I have put together in the appendix of another book called The Abolition of Man; but for our present purpose I need only ask the reader to think what a totally different morality would mean. Think of a country where people were admired for running away in battle, I wear a man felt proud of double-crossing all the people who had been kindest to him. You might just as well try to imagine a country where two and two made five. Men have differed as regards what people you ought to be unselfish to—whether it was only your own family, or your fellow countrymen, or everyone. But they have always agreed that you are not to put yourself first. Selfishness has never been admired. Men have differed as to whether you should have one wife or four. But they have always agreed that you must not simply have any woman you liked.

But the most remarkable thing is this. Whenever you find a man who says he does not believe in a real Right and Wrong, you will find the same man going back on this a moment later. He may break his promise to you, but if you try breaking one to him he will be complaining "It's not fair" before you can say Jack Robinson. The nation may say treaties do not matter; but then, next minute, they spoil their case by saying that the particular treaty they want to break was an unfair one. But if treaties do not matter, and if there is no such thing as Right and Wrong—in other words, if there is no Law of Nature—what is the difference between a fair treaty and an unfair one? Have they not let the cat out of the bag and shown that, whatever they say, they really know the Law of Nature just like anyone else?

It seems, then, we are forced to believe in a real Right and Wrong. People may be sometimes mistaken about them, just as people sometimes get their sums wrong; but they are not a matter of mere taste and opinion anymore than the multiplication table. Now if we are agreed about that, I go on to my next point, which is this. None of us are really keeping the Law of Nature. If there are any exceptions among you, I apologize to them. They had much better read some other work, for nothing I'm going to say concerns them. And now, turning to the ordinary human beings who are left:

I hope you will not misunderstand what I'm going to say. I am not preaching, and heaven knows I do not pretend to be better than anyone else. I am only trying to call attention to the fact; the fact that this year, or this month, or, more likely, this very day, we have failed to practice ourselves the kind of behavior we expect from other people. There may be all sorts of excuses for us. That time you were so unfair to the children was when you were very tired. That slightly shady business about the money—the one you have almost forgotten–came when you were very hard up. And when you promised to do for old So-and-so and have never done–well, you never would have promised if you had known how frightfully busy you were going to be. And as for your behavior to your wife (or husband) or sister (or brother) if I knew how irritating they could be, I would not wonder at it–and who the dickens am I, anyway? I am just the same. That is to say, I do not succeed in keeping the Law of Nature very well, and the moment anyone tells me I am not keeping it, this starts up in my mind a string of excuses as long as your arm. The question at the moment is not whether they are good excuses. The point is that they are one more proof of how deeply, whether we like it or not, we believe in the Law of Nature. If we do not believe in decent behavior, why should we be so anxious to make excuses for not having behaved decently? The truth is, we believe in decency so much–we feel the Rule of Law pressing on us so–that we cannot bear to face the fact that we are breaking it, and consequently we try to shift the responsibility. For you notice that it is only for our bad behavior that we find all these explanations. It is only our bad temper that we put down to being tired or worried or hungry; we put our good temper down to ourselves.

These, then, are the two points I wanted to make. First, that 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. These two facts are the foundations of all clear thinking about ourselves and the universe we live in.

You may say, after all, that what I call breaking the Law of Right and Wrong or of Nature only means that people are not perfect. And why on earth should I expect them to be? That would be a good answer if what I was trying to do was to fix the exact amount of blame which is due to us for not behaving as we expect others to behave. But that is not my job at all. I am not concerned at present with blame; I'm trying to find out truth. And from that point of view the very idea of something being imperfect, of its not being what it ought to be, has certain consequences.

If you take a thing like a stone or a tree, it is what it is and there seems no sense in saying it ought to have been otherwise. Of course you may say a stone is “the wrong shape” if you want to use it for a rockery, or that a tree is a bad tree because it does not give you as much shade as you expected. But all you mean is that the stone or tree does not happen to be convenient for some purpose of your own. You are not, except as a joke, blaming them for that. You really know, that, given the weather and the soil, the tree could not have been any different. What we, from our point of view, call a “bad” tree is obeying the laws of its nature just as much as a “good” one.

Now have you noticed what follows? It follows that what we usually call the laws of nature—the way weather works on a tree for example—may not really be laws in the strict sense, but only in a matter of speaking. When you say that falling stones always obey the laws of gravitation, is not this much the same as saying that the law only means “what stones always do”? You do not really think that when a stone is let go, it suddenly remembers that it is under orders to fall to the ground. You only mean that, in fact, it does fall. In others words, you cannot e sure that there is anything over and over the facts themselves, any law about what ought to happen, as distinct from what does happen. The laws of nature, as applied to stones or trees, may only mean “what Nature, in fact, does.” Bu if you turn to the Law of Human Nature, the Law of Decent Behavior, it is a different matter. That law certainly does not mean “what human beings, in fact, do”; for as I said before, many of them do not obey this law at all, and none of them obey it completely. The law of gravity tells you what stones do if you drop them; but the Law of Human Nature tells you what human beings ought to do and do not. In other words, when you are dealing with humans, something else comes in above and beyond the actual facts. You have the facts (how men do behave) and you also have something else (how they ought to behave). In the rest of the universe there need not be anything but the facts. Electrons and molecules behave in a certain way, and certain results follow, and that may be the whole story. But men behave in a certain way and that is not the whole story, for all the time you know that they ought to behave differently.

Now this is really so peculiar that one is tempted to try to explain it away. For instance, we might try to make out that when you say a man ought not to act as he does, you only mean the same as when you say that a stone is the wrong shape; namely, that what he is doing happens to be inconvenient to you. But that is simply untrue. A man occupying the corner seat in the train because he got there first, and a man who slipped into it while my back was turned and removed my bag, are both equally inconvenient. But I blame the second man and do not blame the first. I am not angry—except perhaps for a moment before I come to my senses—with a man who trips me up by accident; I am angry with a man who tries to trip me up even if he does not succeed. Yet the first has hurt me and the second has not. Sometimes the behavior which I call bad is not inconvenient to me at all, but the very opposite. In war, each side may find a traitor on the other side very useful. But thought they use him and pay him they regard him as human vermin. So you cannot say that what we call decent behavior in others is simply the behavior that happens to be useful to us. And as for decent behavior in ourselves, I suppose it is pretty obvious that it does not mean the behavior that pays. It means things like being content with 30 shillings when you might have got 3 pounds, doing school work honestly when it would be easy to cheat, leaving a girl alone when you would like to make love to her, staying in dangerous places when you could go somewhere safer, keeping promises you would rather not keep, and telling the truth even when it makes you look a fool.

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 everyone 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. 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 may 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,” for trying to benefit society, in other words being unselfish (for “society” after all only means “other people”), is one of the things decent behavior consists in; all you are really saying is that decent behavior is decent behavior. You would have said just as much if you have stopped at the statement, “Men ought to be unselfish.” Not that they are unselfish, but that they ought to be. The Moral Law, or Law of Human Nature, is not simply a fact about human behavior in the same way as the Law of Gravitation is, or may be, simply a fact about how heavy objects behave. On the other hand, it is not mere fancy, for we cannot get rid of the idea, and most of the things we say and think about men would be reduced to nonsense if we did. And it is not simply a statement about how we should like men to behave for our own convenience; for the behavior we call bad or unfair is not exactly the same as the behavior we find inconvenient, and may even be the opposite. Consequently, the Rule of Right and Wrong, or Law of Human Nature, or whatever you call it, must somehow or other be a real thing—a thing that is really there, not made up by ourselves. And yet it is not a fact in the ordinary sense, in the same way as our actual behavior is a fact. It begins to look as if we shall have to admit that there is more than one kind of reality; that, in this particular case, there is something above and beyond the ordinary facts of men’s behavior, and yet quite definitely real—a real law, which none of us made, but which we find pressing on us.

So what does this tell us about the universe we live in? Ever since men were able to think, they have been wondering what this universe really is and how it came to be there. And, very roughly, two views have been held. First, there is what is called the materialist view. People who take that view think that matter and space just happen to exist, and always have existed, nobody knows why; and that the matter, behaving in certain fixed ways, had just happened, by a sort of fluke, to produce creature like ourselves who are able to think. By one chance in a thousand something hit our sun and made it produce the planets; and by another thousandth chance the chemicals necessary for life, and the right temperature, occurred on one of these planets, and so some of the matter on this earth came alive; and then, by a very long series of chances, the living creatures developed into things like us. The other view is the religious view. According to it, what is behind the universe is more like a mind than it is like anything else we know. That is to say, it is conscious, and has purposes, and prefers one thing to another. And on this view it made the universe, partly for purposes we do not know, but partly, at any rate, in order to produce creatures like itself—I mean, like itself to the extent of having minds. Please do not think that one of these views was held a long time ago and that the other has gradually taken its place. Wherever there have been thinking men both views turn up. And note this too. You cannot find out which view is the right one by science in the ordinary sense. Science works by experiments. It watches how things behave. Every scientific statement I n the long run, however complicated it looks, really means something like, “I pointed the telescope to such and such a part of the sky at 2:20 A.M. on January 15th and saw so-and-so,” or, “I put some of this stuff in a pot and heated it to such-and-such a temperature and it did so-and-so.” Do not think I am saying anything against science: I am only saying what its job is. And the more scientific a man is, the more (I believe) he would agree with me that this is the job of science—and a very useful and necessary job it is too. But why anything comes to be there at all, and whether there is anything behind the things science observes—something of a different kind—this is not a scientific question. If there is “Something Behind,” then either it will have to remain altogether unknown to men or else make itself known in some different way. The statement that there is any such thing, and the statement that there is no such thing, are neither of them statements that science can make. And real scientists do not usually make them. It is usually the journalists and popular novelists who have picked up a few odds and ends of half-baked science from textbooks who go in for them. After all, it is really a matter of common sense. Supposing science ever became complete so that it knew every single thing in the whole universe. Is it not plain that the question, “Why is there a universe?” “Why does it go on as it does?” “Has it any meaning?” would remain just as they were?

Now the position would be quite hopeless but for this. There is one thing, and only one, in the whole universe which we know more about than we could learn from external observation. That one thing is Man. We do not merely observe men, we are men. In this case we have, so to speak, inside information we are in the know. And because of that, we know that men find themselves under a moral law, which they did not make, and cannot quite forget even when they try, and which they know they ought to obey. Notice the following point. Anyone studying Man from the outside as we study electricity or cabbages, not knowing our language and consequently not able to get any inside knowledge from us, but merely observing what we did, would never get the slightest evidence that we had this moral law. How could he? For his observations would only show what we did, and the moral law is about what we ought to do. In the same way, if there were anything above or behind the observed facts in the case of stones or the weather, we, by studying them from outside, could never hope to discover it.

The position of the question, then, is like this. We want to know whether the universe simply happens to be what it is for no reason or whether there is a power behind it that makes it what it is. Since that power, if it exists, would be not one of the observed facts but a reality which makes them, no mere observation of the facts can find it. There is only one case in which we can know whether there is anything more, namely our own case, and in that one case we find there is. Or put it the other way round. If there was a controlling power outside the universe, it could not show itself to us as one of the facts inside the universe—not more than the architect of a house could actually be a wall or staircase or fireplace in that house. The only way in which we could expect it to show itself would be inside ourselves as an influence or a command trying to get us to behave in a certain way. And that is just what we do find inside ourselves. Surely this ought to arouse our suspicions? In the only case where you can expect to get an answer, the answer turns out to be Yes; and in the other cases, where you do not get an answer, you see why you do not. Supposed someone asked me, when I see a man in a blue uniform going down the street leaving little paper packets at each house, why I supposed that they contain letters? I should reply, “Because whenever he leaves a similar little packet for me I find it does contain a letter.” And if he then objected, “But you’ve never seen all these letter which you think the other people are getting,” I should say, “Of course not, and I shouldn’t expect to, because they’re not addressed to me. I’m explaining the packets I’m not allowed to open by the ones I am allowed to open.” It is the same about this question. The only packet I am allowed to open is Man. When I do, especially when I open that particular man called Myself, I find that I do not exist on my own, that I am under a law; that somebody or something wants me to behave in a certain way. I do not, of course, think that if I could get inside a stone or a tree I should find exactly the same thing, just as I do not think all the other people in the street get the same letters as I do. I should expect, for instance, to find that the stone had to obey the law of gravity—that whereas the sender of the letters merely tells me to obey the law of my human nature, He compels the stone to obey the laws of its stony nature. But I should expect to find that there was, so to speak, a sender of letters in both cases, a Power behind the facts, a Director, a Guide.

Do not think I am going faster than I really am. I am not yet within a hundred miles of the God of Christian theology. All I have got to is a Something which is directing the universe, and which appears in me as a law urging me to do right and make me feel responsible and uncomfortable when I do wrong. I think we have to assume it is more like a mind than it is like anything else we know—because after all the only other thing we know is matter and you can hardly imagine a bit of matter giving instructions. But, of course, it need not be very like a mind, still less like a person.

I expect now you have felt a certain annoyance or that I played a trick on you—that I have carefully wrapped up to look like philosophy what turns out to be one more “religious jaw.” You may have felt you were ready to listen to me as long as you thought I had anything new to say; but if it turns out to be only religion, well, the world has tried that and you cannot put the clock back. If anyone if feeling that way I should like to say three things to him.

First, as to putting the clock back. Would you think I was joking if I said that you can put a clock back, and that if the clock is wrong it is often a very sensible thing to do? But I would rather get away from that whole idea of clocks. We all want progress. But progress means getting nearer to the place where you want to be. And if you have taken a wrong turning, then to go forward does not get you any nearer. If you are on the wrong road, progress means doing an about-turn and walking back to the right road; and in that case the man who turns back soonest is the most progressive man. We have all seen this when doing arithmetic. When I have started a sum the wrong way, the sooner I admit this and go back and start over again, the faster I shall get on. There is nothing progressive about being pigheaded and refusing to admit a mistake. And I think if you look at the present state of the world, it is pretty plan that humanity has been making some big mistake. We are on the wrong road. And if that is so, we must go back. Going back is the quickest way on.

Then, secondly, this has not yet turned exactly into a “religious jaw.” We have not yet got as far as the God of any actual religion, still less the god of that particular religion called Christianity. We have only got as far as a Somebody or Something behind the Moral Law. We are not taking anything from the Bible or the Churches, we are trying to see what we can find out about this Somebody on our own steam. And I want to make it quite clear that what we find out on our own steam is something that gives us a shock. We have two bits of evidence about the Somebody. One is the universe He has made. If we used that as our only clue, then I think we should have to conclude that He was a great artist (for the universe is a very beautiful place), but also that He is quite merciless and no friend to man (for the universe is a very dangerous and terrifying place). The other bit of evidence is that Mora Law which He has put into our minds. And this is a better bit of evidence than the other, because it is inside information. You find out more about God from the Moral Law than from the universe in general just as you find out more about a man by listening to his conversation than by looking at a house he has built. Now, from this second bit of evidence we conclude that the Being behind the universe is intensely interested in right conduct—in fair play, unselfishness, courage, good faith, honesty and truthfulness. In that sense we should agree with the account given by Christianity and some other religions, that God is “good.” But do not let us go too fast here. The Moral law does not give us any grounds for thinking that God is “good” in the sense of being indulgent about the Moral Law. It is as hard as nails. It tells you to do the straight thing and it does not seem to care how painful, or dangerous, or difficult it is to do. If God is like the Moral Law, then he is not soft. It is no use, at this stage, saying that what you mean by a “good” God is a God who can forgive. You are going too quickly. Only a Person can forgive. And we have not yet got as far as a personal God—only as far as a power, behind the Moral Law, and more like a mind than it is like anything else. But it may still be very unlike a Person. If it is pure impersonal mind, there may be no sense in asking it to make allowances for you or let you off, just as there is no sense in asking the multiplication table to let you off when you do your sums wrong. You are bound to get the wrong answer. And it is no use either saying that if there is a God of that sort—an impersonal absolute goodness—then you do not like Him and are not going to bother about Him. For the trouble is that one part of you is on His side and really agrees with His disapproval of human greed and trickery and exploitation. You may want Him to make an exception in your own case, to let you off this one time; but you know at bottom that unless the power behind the world really and unalterably detests that sort of behavior, then he cannot be good. On the other hand, we know that if there does exist an absolute goodness it must hate most of what we do. That is the terrible fix we are in. if the universe is not governed by an absolute goodness, then all our efforts are in the long run hopeless. But if it is, then we are making ourselves enemies to that goodness every day, and are not in the least likely to do any better tomorrow, and so our case is hopeless again. We cannot do without it, and we cannot do with it. God is the only comfort, He is also the supreme terror: the thing we most need and the thing we most want to hide from. He is our only possible ally, and we have made ourselves His enemies. Some people talk as if meeting the gaze of absolute goodness would be fun. They need to think again. They are still only playing with religion. Goodness is either the great safety or the great danger—according to the way you react to it. And we have reacted the wrong way.

Now to my third point. When I chose to get to my real subject in this roundabout way, I was not trying to play any kind of trick on you. I had a different reason. My season was that Christianity simply does not make sense until you have faced the sort of facts I have been describing. Christianity tells people to repent and promises them forgiveness. It therefore has nothing (as far as I know) to say to people who do not know they have done anything to repent of and who do not feel that they need any forgiveness. It is after you have realized that there is a real Moral Law, and a Power behind the law, and that you have broken that law and put yourself wrong with that Power—it is after all this, and not a moment sooner, that Christianity begins to talk. When you know you are sick, you will listen to the doctor. When you have realized that our position is nearly desperate you will begin to understand what the Christians are talking about. They offer an explanation of how we got into our present state of both hating goodness and loving it. They offer an explanation of how God can be this impersonal mind at the back of the Moral Law and yet also a Person. They tell you how the demands of this law, which you and I cannot meet, have been met on our behalf, how God Himself becomes a man to save man from the disapproval of God. It is an old story and if you want to go into it you will no doubt consult people who have more authority to talk about it than I have. All I am doing is to ask people to face the facts—to understand the questions which Christianity claims to answer. And they are very terrifying facts. I wish it was possible to say something more agreeable. But I must say what I think true. Of course, I quite agree that the Christian religion is, in the long run, a thin of unspeakable comfort. But it does not begin in comfort; it begins in the dismay I have been describing, and it is no use at all trying to go on to that comfort without first going through that dismay. If you look for truth, you may find comfort in the end: If you look for comfort you will not get either comfort or truth—only soft soap and wishful thinking to begin with and, in the end, despair. Most of us have got over the prewar wishful thinking about international politics. It is time we did the same about religion.
