       5 SEXUAL MORALITY

      We must now consider Christian morality as regards sex, what Christians call the virtue of chastity. The Christian rule of chastity must not be confused with the social rule of ‘modesty’ (in one sense of that word); i.e. propriety, or decency. The social rule of propriety lays down how much of the human body should be displayed and what subjects can be referred to, and in what words, according to the customs of a given social circle. 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 unchaste). Some of the language which chaste women used in Shakespeare’s time would have been used in the nineteenth century only by a woman completely abandoned. When people break the rule of propriety current in their own time and place, if they do so in order to excite lust in themselves or others, then they are offending against chastity. But if they break it through ignorance or carelessness they are guilty only of bad manners. When, as often happens, they break it defiantly in order to shock or embarrass others, they are not necessarily being unchaste, but they are being uncharitable: for it is uncharitable to take pleasure in making other people uncomfortable. I do not think that a very strict or fussy standard of propriety is any proof of chastity or any help to it, and I therefore regard the great relaxation and simplifying of the rule which has taken place in my own lifetime as a good thing. At its present stage, however, it has this inconvenience, that people of different ages and different types do not all acknowledge the same standard, and we hardly know where we are. While this confusion lasts I think that old, or old-fashioned, people should be very careful not to assume that young or ‘emancipated’ people are corrupt whenever they are (by the old standard) improper; and, in return, that young people should not call their elders prudes or puritans because they do not easily adopt the new standard. A real desire to believe all the good you can of others and to make others as comfortable as you can will solve most of the problems.

      Chastity is the most unpopular of the Christian virtues. There is no getting away from it; the Christian rule is, ‘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.

      But I have other reasons for thinking so. The biological purpose of sex is children, just as the biological purpose of eating is to repair the body. Now if we eat whenever we feel inclined and just as much as we want, it is quite true most of us will eat too much: but not terrifically too much. One man may eat enough for two, but he does not eat enough for ten. The appetite goes a little beyond its biological purpose, but not enormously. But if a healthy young man indulged his sexual appetite whenever he felt inclined, and if each act produced a baby, then in ten years he might easily populate a small village. This appetite is in ludicrous and preposterous excess of its function.

      Or take it another way. You can get a large audience together for a strip-tease act—that is, to watch a girl undress on the stage. Now suppose you come to a country where you could fill a theatre by simply bringing a covered plate on to the stage and then slowly lifting the cover so as to let every one see, just before the lights went out, that it contained a mutton chop or a bit of bacon, would you not think that in that country something had gone wrong with the appetite for food? And would not anyone who had grown up in a different world think there was something equally queer about the state of the sex instinct among us?

      One critic said that if he found a country in which such strip-tease acts with food were popular, he would conclude that the people of that country were starving. He meant, of course, to imply that such things as the strip-tease act resulted not from sexual corruption but from sexual starvation. I agree with him that if, in some strange land, we found that similar acts with mutton chops were popular, one of the possible explanations which would occur to me would be famine. But the next step would be to test our hypothesis by finding out whether, in fact, much or little food was being consumed in that country. If the evidence showed that a good deal was being eaten, then of course we should have to abandon the hypothesis of starvation and try to think of another one. In the same way, before accepting sexual starvation as the cause of the strip-tease, we should have to look for evidence that there is in fact more sexual abstinence in our age than in those ages when things like the strip-tease were unknown. But surely there is no such evidence. Contraceptives have made sexual indulgence far less costly within marriage and far safer outside it than ever before, and public opinion is less hostile to illicit unions and even to perversion than it has been since Pagan times. Nor is the hypothesis of ‘starvation’ the only one we can imagine. Everyone knows that the sexual appetite, like our other appetites, grows by indulgence. Starving men may think much about food, but so do gluttons; the gorged, as well as the famished, like titillations.

      Here is a third point. You find very few people who want to eat things that really are not food or to do other things with food instead of eating it. In other words, perversions of the food appetite are rare. But perversions of the sex instinct are numerous, hard to cure, and frightful. I am sorry to have to go into all these details but I must. The reason why I must is that you and I, for the last twenty years, have been fed all day long on good solid lies about sex. We have been told, till one is sick of hearing it, that sexual desire is in the same state as any of our other natural desires and that if only we abandon the silly old Victorian idea of hushing it up, everything in the garden will be lovely. It is not true. The moment you look at the facts, and away from the propaganda, you see that it is not.

      They tell you sex has become a mess because it was hushed up. But for the last twenty years it has not been. It has been chattered about all day long. Yet it is still in a mess. If hushing up had been the cause of the trouble, ventilation would have set it right. But it has not. I think it is the other way round. I think the human race originally hushed it up because it had become such a mess. Modern people are always saying, ‘Sex is nothing to be ashamed of.’ They may mean two things. They may mean ‘There is nothing to be ashamed of in the fact that the human race reproduces itself in a certain way, nor in the fact that it gives pleasure.’ If they mean that, they are right. Christianity says the same. It is not the thing, nor the pleasure, that is the trouble. The old Christian teachers said that if man had never fallen, sexual pleasure, instead of being less than it is now, would actually have been greater. I know some muddle-headed Christians have talked as if Christianity thought that sex, or the body, or pleasure, were bad in themselves. But they were wrong. Christianity is almost the only one of the great religions which thoroughly approves of the body—which believes that
