Mere Christianity

by C.S. Lewis

When you have reached your own room, be kind to those who have chosen different doors and to those who are still in the hall. If they are wrong they need your prayers all the more; and if they are your enemies, then you are under orders to pray for them. That is one of the rules common to the whole house.

Quarrelling 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;

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.

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.

The Moral Law tells us the tune we have to play: our instincts are merely the keys.

There is not one of them which will not make us into devils if we set it up as an absolute guide.

“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?

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.

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.

Suppose someone asked me, when I see a man in blue uniform going down the street leaving little paper packets at each house, why I suppose 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 letters 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.

Consequently atheism turns out to be too simple. If the whole universe has no meaning, we should never have found out that it has no meaning: just as, if there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be a word without meaning.

Reality, in fact, is usually something you could not have guessed. That is one of the reasons I believe Christianity. It is a religion you could not have guessed.

You can do a kind action when you are not feeling kind and when it gives you no pleasure, simply because kindness is right; but no one ever did a cruel action simply because cruelty is wrong—only because cruelty was pleasant or useful to him. In other words badness cannot succeed even in being bad in the same way in which goodness is good. Goodness is, so to speak, itself: badness is only spoiled goodness.

And do you now begin to see why Christianity has always said that the devil is a fallen angel? That is not a mere story for the children. It is a real recognition of the fact that evil is a parasite, not an original thing. The powers which enable evil to carry on are powers given it by goodness. All the things which enable a bad man to be effectively bad are in themselves good things—resolution, cleverness, good looks, existence itself.

“I’m not going to go and make you tidy the schoolroom every night. You’ve got to learn to keep it tidy on your own.” Then she goes up one night and finds the Teddy bear and the ink and the French Grammar all lying in the grate. That is against her will. She would prefer the children to be tidy. But on the other hand, it is her will which has left the children free to be untidy. The same thing arises in any regiment, or trade union, or school. You make a thing voluntary and then half the people do not do it. That is not what you willed, but your will has made it possible.

When we have understood about free will, we shall see how silly it is to ask, as somebody once asked me: “Why did God make a creature of such rotten stuff that it went wrong?” The better stuff a creature is made of—the cleverer and stronger and freer it is—then the better it will be if it goes right, but also the worse it will be if it goes wrong. A cow cannot be very good or very bad; a dog can be both better and worse; a child better and worse still; an ordinary man, still more so; a man of genius, still more so; a superhuman spirit best—or worst—of all.

God cannot give us a happiness and peace apart from Himself, because it is not there. There is no such thing.

A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic—on a level with the man who says he is a poached egg—or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God: or else a madman or something worse.

Ninety-nine per cent. of the things you believe are believed on authority.

mistake. Perfect behaviour may be as unattainable as perfect gear-changing when we drive; but it is a necessary ideal prescribed for all men by the very nature of the human machine just as perfect gear-changing is an ideal prescribed for all drivers by the very nature of cars.

You can get the idea plain if you think of us as a fleet of ships sailing in formation. The voyage will be a success only, in the first place, if the ships do not collide and get in one another’s way; and, secondly, if each ship is seaworthy and has her engines in good order.

Morality, then, seems to be concerned with three things. Firstly, with fair play and harmony between individuals. Secondly, with what might be called tidying up or harmonising the things inside each individual. Thirdly, with the general purpose of human life as a whole: what man was made for: what course the whole fleet ought to be on: what tune the conductor of the band wants it to play.

says that a thing cannot be wrong unless it hurts some other human being. He quite understands that he must not damage the other ships in the convoy, but he honestly thinks that what he does to his own ship is simply his own business. But does it not make a great difference whether his ship is his own property or not? Does it not make a great difference whether I am, so to speak, the landlord of my own mind and body, or only a tenant, responsible to the real landlord? If somebody else made me, for his own purposes, then I shall have a lot of duties which I should not have if I simply belonged to myself.

He told us to be not only “as harmless as doves,” but also “as wise as serpents.” He wants a child’s heart, but a grown-up’s head. He wants us to be simple, single-minded, affectionate, and teachable, as good children are; but He also wants every bit of intelligence we have to be alert at its job, and in first-class fighting trim.

But the truth is that right actions done for the wrong reason do not help to build the internal quality or character called a “virtue,” and it is this quality or character that really matters.

The point is not that God will refuse you admission to His eternal world if you have not got certain qualities of character: the point is that if people have not got at least the beginnings of those qualities inside them, then no possible external conditions could make a “Heaven” for them—that is, could make them happy with the deep, strong, unshakable kind of happiness God intends for us.

Really great moral teachers never do introduce new moralities: it is quacks and cranks who do that. As Dr. Johnson said, “People need to be reminded more often than they need to be instructed.” The real job of every moral teacher is to keep on bringing us back, time after time, to the old simple principles which we are all so anxious not to see; like bringing a horse back and back to the fence it has refused to jump or bringing a child back and back to the bit in its lesson that it wants to shirk.

When it tells you to feed the hungry it does not give you lessons in cookery. When it tells you to read the Scriptures it does not give you lessons in Hebrew and Greek, or even in English grammar. It was never intended to replace or supersede the ordinary human arts and sciences: it is rather a director which will set them all to the right jobs, and a source of energy which will give them all new life, if only they will put themselves at its disposal.

Most of us are not really approaching the subject in order to find out what Christianity says: we are approaching it in the hope of finding support from Christianity for the views of our own party.

really want it: and we are not going to want it until we become fully Christian. I may repeat “Do as you would be done by” till I am black in the face, but I cannot really carry it out till I love my neighbour as myself: and I cannot learn to love my neighbour as myself till I learn to love God: and I cannot learn to love God except by learning to obey Him.

Thus, while the rule of chastity is the same for all Christians at all times, the rule of propriety changes. A girl in the Pacific islands wearing hardly any clothes and a Victorian lady completely covered in clothes might both be equally “modest,” proper, or decent, according to the standards of their own societies: and both, for all we could tell by their dress, might be equally chaste (or equally uhchaste).

“Either marriage, with complete faithfulness to your partner, or else total abstinence.” Now this is so difficult and so contrary to our instincts, that obviously either Christianity is wrong or our sexual instinct, as it now is, has gone wrong. One or the other. Of course, being a Christian, I think it is the instinct which has gone wrong.

the gorged, as well as the famished, like titillations.

man with an obsession is a man who has very little sales-resistance.

In the second place, many people are deterred from seriously attempting Christian chastity because they think (before trying) that it is impossible. But when a thing has to be attempted, one must never think about possibility or impossibility. Faced with an optional question in an examination paper, one considers whether one can do it or not: faced with a compulsory question, one must do the best one can. You may get some marks for a very imperfect answer: you will certainly get none for leaving the question alone.

We may, indeed, be sure that perfect chastity—like perfect charity—will not be attained by any merely human efforts. You must ask for God’s help. Even when you have done so, it may seem to you for a long time that no help, or less help than you need, is being given. Never mind. After each failure, ask forgiveness, pick yourself up, and try again. Very often what God first helps us towards is not the virtue itself but just this power of always trying again. For however important chastity (or courage, or truthfulness, or any other virtue) may be, this process trains us in habits of the soul which are more important still. It cures our illusions about ourselves and teaches us to depend on God.

What they all disagree with is the modern view that it is a simple readjustment of partners, to be made whenever people feel they are no longer in love with one another, or when either of them falls in love with someone else.

If people do not believe in permanent marriage, it is perhaps better that they should live together unmarried than that they should make vows they do not mean to keep. It is true that by living together without marriage they will be guilty (in Christian eyes) of fornication. But one fault is not mended by adding another: unchastity is not improved by adding perjury.

those who are in love have a natural inclination to bind themselves by promises. Love songs all over the world are full of vows of eternal constancy. The Christian law is not forcing upon the passion of love something which is foreign to that passion’s own nature: it is demanding that lovers should take seriously something which their passion of itself impels them to do.

Love in this second sense—love as distinct from “being in love”—is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by (in Christian marriages) the grace which both partners ask, and receive, from God. They can have this love for each other even at those moments when they do not like each other; as you love yourself even when you do not like yourself. They can retain this love even when each would easily, if they allowed themselves, be “in love” with someone else. “Being in love” first moved them to promise fidelity: this quieter love enables them to keep the promise. It is on this love that the engine of marriage is run: being in love was the explosion that started it.

A great many people seem to think that if you are a Christian yourself you should try to make divorce difficult for every one. I do not think that. At least I know I should be very angry if the Mohammedans tried to prevent the rest of us from drinking wine. My own view is that the Churches should frankly recognise that the majority of the British people are not Christians and, therefore, cannot be expected to live Christian lives. There ought to be two distinct kinds of marriage: one governed by the State with rules enforced on all citizens, the other governed by the Church with rules enforced by her on her own members. The distinction ought to be quite sharp, so that a man knows which couples are married in a Christian sense and which are not.

Do I think well of myself, think myself a nice chap? Well, I am afraid I sometimes do (and those are, no doubt, my worst moments) but that is not why I love myself. In fact it is the other way round: my self-love makes me think myself nice, but thinking myself nice is not why I love myself. So loving my enemies does not apparently mean thinking them nice either. That is an enormous relief. For a good many people imagine that forgiving your enemies means making out that they are really not such bad fellows after all, when it is quite plain that they are. Go a step further. In my most clear-sighted moments not only do I not think myself a nice man, but I know that I am a very nasty one. I can look at some of the things I have done with horror and loathing. So apparently I am allowed to loathe and hate some of the things my enemies do.

There are two Greek words: the ordinary word to kill and the word to murder. And when Christ quotes that commandment He uses the murder one in all three accounts, Matthew, Mark, and Luke.

Pride leads to every other vice: it is the complete anti-God state of mind.

We say that people are proud of being rich, or clever, or good-looking, but they are not. They are proud of being richer, or cleverer, or better-looking than others.

Nearly all those evils in the world which people put down to greed or selfishness are really far more the result of Pride.

As long as you are proud you cannot know God. A proud man is always looking down on things and people: and, of course, as long as you are looking down, you cannot see something that is above you.

If anyone would like to acquire humility, I can, I think, tell him the first step. The first step is to realise that one is proud. And a biggish step, too. At least, nothing whatever can be done before it. If you think you are not conceited, it means you are very conceited indeed.

Do not waste time bothering whether you “love” your neighbour; act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him.

The worldly man treats certain people kindly because he “likes” them: the Christian, trying to treat every one kindly, finds himself liking more and more people as he goes on—including people he could not even have imagined himself liking at the beginning.
