  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 any more 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 apologise to them. They had much better read some other book, for nothing I am going to say concerns them. And now, turning to the ordinary human beings who are left:

  I hope you will not misunderstand what I am 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 a fact; the fact that this year, or this month, or, more likely, this very day, we have failed to practise ourselves the kind of behaviour 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 what 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 behaviour 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, there 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 behaviour, 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 or 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 behaviour 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 foundation of all clear thinking about ourselves and the universe we live in.

  SOME OBJECTIONS

  If they are the foundation, I had better stop to make that foundation firm before I go on. Some of the letters I have had show that a good many people find it difficult to understand just what this Law of Human Nature, or Moral Law, or Rule of Decent Behaviour is.

  For example, some people wrote to me saying, ‘Isn’t what you call the Moral Law simply our herd instinct and hasn’t it been developed just like all our other instincts?’ Now I do not deny that we may have a herd instinct: but that is not what I mean by the Moral Law. We all know what it feels like to be prompted by instinct–by mother love, or sexual instinct, or the instinct for food. It means that you feel a strong want or desire to act in a certain way. And, of course, we sometimes do feel just that sort of desire to help another person: and no doubt that desire is due to the herd instinct. But feeling a desire to help is quite different from feeling that you ought to help whether you want to or not. Supposing you hear a cry for help from a man in danger. You will probably feel two desires–one a desire to give help (due to your herd instinct), the other a desire to keep out of danger (due to the instinct for self-preservation). But you will find inside you, in addition to these two impulses, a third thing which tells you that you ought to follow the impulse to help, and suppress the impulse to run away. Now this thing that judges between two instincts, that decides which should be encouraged, cannot itself be either of them. You might as well say that the sheet of music which tells you, at a given moment, to play one note on the piano and not another, is itself one of the notes on the keyboard. The Moral Law tells us the tune we have to play: our instincts are merely the keys.

  Another way of seeing that the Moral Law is not simply one of our instincts is this. If’ two instincts are in conflict, and there is nothing in a creature’s mind except those two instincts, obviously the stronger of’ the two must win. But at those moments when we are most conscious of the Moral Law, it usually seems to be telling us to side with the weaker of the two impulses. You probably want to be safe much more than you want to help the man who is drowning: but the Moral Law tells you to help him all the same. And surely it often tells us to try to make the right impulse stronger than it naturally is? I mean, we often feel it our duty to stimulate the herd instinct, by waking up our imaginations and arousing our pity and so on, so as to get up enough steam for doing the right thing. But clearly we are not acting from instinct when we set about making an instinct stronger than it is. The thing that says to you, ‘Your herd instinct is asleep. Wake it up,’ cannot itself be the herd instinct. The thing that tells you which note on the piano needs to be played louder cannot itself be that note.

  Here is a third way of seeing it. If the Moral Law was one of our instincts, we ought to be able to point to some one impulse inside us which was always what we call ‘ good,’ always in agreement with the rule of right behaviour. But you cannot. There is none of our impulses which the Moral Law may not sometimes tell us to suppress, and none which it may not sometimes tell us to encourage. It is a mistake to think that some of our impulses–say mother love or patriotism–are good, and others, like sex or the fighting instinct, are bad. All we mean is that the occasions on which the fighting instinct or the sexual desire need to be restrained are rather more frequent than those for restraining mother love or patriotism. But there are situations in which it is the duty of a married man to encourage his sexual impulse and of a soldier to encourage the fighting instinct. There are also occasions on which a mother’s love for her own children or a man’s love for his own country have to be suppressed or they will lead to unfairness towards other people’s children or countries. Strictly speaking, there are no such things as good and bad impulses. Think once again of a piano. It has not got two kind 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 any set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts.

  By the way, this point is of great practical consequence. The most dangerous thing you can do is to take any one impulse of your own nature and set it up as the thing you ought to follow at all costs. There is not one of them which will not make us into devils if we set it up as an absolute guide. You might think love of humanity in general was safe, but it is not. If you leave out justice you will find yourself breaking agreements and faking evidence in trials ‘for the sake of humanity,’ and become in the end a cruel and treacherous man.

  Other people wrote to me saying, ‘Isn’t what you call the Moral Law just a social convention, something that is put into us by education?’ I think there is a misunderstanding here. The people who ask that question are usually taking it for granted that if we have learned a thing from parents and teachers, then that thing must be merely a human invention. But, of course, that is not so. We all learned the multiplication table at school. A child who grew up alone on a desert island would not know it. But surely it does not follow that the multiplication table is simply a human convention, something human beings have made up for themselves and might have made different if they had liked? I fully agree that we learn the Rule of Decent Behaviour from parents and teachers, a
nd friends and books, as we learn everything else. But some of the things we learn are mere conventions which might have been different–we learn to keep to the left of the road, but it might just as well have been the rule to keep to the right–and others of them, like mathematics, are real truths. The question is to which class the Law of Human Nature belongs.

  There are two reasons for saying it belongs to the same class as mathematics. The first is, as I said in the first chapter, that though there are differences between the moral ideas of one time or country and those of another, the differences are not really very great–not nearly so great as most people imagine–and you can recognise the same law running through them all: whereas mere conventions, like the rule of the road or the kind of clothes people wear, may differ to any extent. The other reason is this. When you think about these differences between the morality of one people and another, do you think that the morality of one people is ever better or worse than that of another? Have any of the changes been improvements? If not, then of course there could never be any moral progress. Progress means not just changing, but changing for the better. If no set of moral ideas were truer or better than any other, there would be no sense in preferring civilised 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. We do believe that some of the people who tried to change the moral ideas of their own age were what we would call Reformers or Pioneers–people who understood morality better than their neighbours did. Very well then. 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, saying that one of them conforms to that standard more nearly than the other. But 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. Or put it this way. If your moral ideas can be truer, and those of the Nazis less true, there must be something-some Real Morality–for them to be true about. The reason why your idea of New York can be truer or less true than mine is that New York is a real place, existing quite apart from what either of us thinks. If when each of us said ‘New York’ each means merely ‘The town I am imagining in my own head,’ how could one of us have truer ideas than the other? There would be no question of truth or falsehood at all. In the same way, if the Rule of Decent Behaviour meant simply ‘whatever each nation happens to approve,’ there would be no sense in saying that any one nation had ever been more correct in its approval than any other; no sense in saying that the world could ever grow morally better or morally worse.

  I conclude then, that though the differences between people’s ideas of Decent Behaviour often make you suspect that there is no real natural Law of Behaviour at all, yet the things we are bound to think about these differences really prove just the opposite. But one word before I end. I have met people who exaggerate the differences, because they have not distinguished between differences of morality and differences of belief about facts. For example, one man said to me, ‘Three hundred years ago people in England were putting witches to death. Was that what you call the Rule of Human Nature or Right Conduct?’ But surely the reason we do not execute witches is that we do not believe there are such things. If we did–if we really thought that there were people going about who had sold themselves to the devil and received supernatural powers from him in return and were using these powers to kill their neighbours or drive them mad or bring bad weather–surely we would all agree that if anyone deserved the death penalty, then these filthy quislings did? There is no difference of moral principle here: the difference is simply about matter of fact. It may be a great advance in knowledge not to believe in witches: there is no moral advance in not executing them when you do not think they are there. You would not call a man humane for ceasing to set mousetraps if he did so because he believed there were no mice in the house.

  CHAPTER 3

  THE REALITY OF THE LAW

  I now go back to-what I said at the end of the first chapter, that there were two odd things about the human race. First, that they were haunted by the idea of a sort of behaviour they ought to practise, what you might call fair play, or decency, or morality, or the Law of Nature. Second, that they did not in fact do so. Now some of you may wonder why I called this odd. It may seem to you the most natural thing in the world. In particular, you may have thought I was rather hard on the human race. After all, you may say, 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 am 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 the 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 manner of speaking. When you say that falling stones always obey the law 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 other words, you cannot be sure that there is anything over and above 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’. But if you turn to the Law of Human Nature, the Law of Decent Behaviour, 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.

  *I do not think it is the whole story, as you will see later. I mean that, as far as argument has gone up to date, it may be.

  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 b
ack 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 behaviour 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 though they use him and pay him they regard him as human vermin. So you cannot say that what we call decent behaviour in others is simply the behaviour that happens to be useful to us. And as for decent behaviour in ourselves, I suppose it is pretty obvious that it does not mean the behaviour that pays. It means things like being content with thirty shillings when you might have got three 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 any 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. 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 he 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.’

  And that is where I do stop. Men ought to be unselfish, ought to be fair. Not that men are unselfish, not that they like being unselfish, but that they ought to be. The Moral Law, or Law of Human Nature, is not simply a fact about human behaviour 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 a 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 behaviour we call bad or unfair is not exactly the same as the behaviour we find inconvenient, and may even be the opposite. Consequently, this 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 behaviour 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 it is not a fact in the ordinary sense, in the same way as our actual behaviour 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 behaviour, and yet quite definitely real–a real law, which none of us made, but which we find pressing on us.

  WHAT LIES BEHIND THE LAW

  Let us sum up what we have reached so far. In the case of stones and trees and things of that sort, what we call the Laws of Nature may not be anything except a way of speaking. When you say that nature is governed by certain laws, this may only mean that nature does, in fact, behave in a certain way. The so-called laws may not be anything real–anything above and beyond the actual facts that we observe. But in the case of Man we saw that this will not do. The Law of Human Nature, or of Right and Wrong, must he something above and beyond the actual facts of human behaviour. In this case, besides the actual facts, you have something
