Book 3: Christian Behaviour Chapter 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 old 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 that 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 came 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 striptease 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 pop...
