Mere Christianity - C. S. Lewis [40]
If they mean that, I think they are wrong. I think it is everything to be ashamed of. There is nothing to be ashamed of in enjoying your food: there would be everything to be ashamed of if half the world made food the main interest of their lives and spent their time looking at pictures of food and dribbling and smacking their lips. I do not say you and I are individually responsible for the present situation. Our ancestors have handed over to us organisms which are warped in this respect: and we grow up surrounded by propaganda in favour of unchastity. There are people who want to keep our sex instinct inflamed in order to make money out of us. Because, of course, a man with an obsession is a man who has very little sales-resistance. God knows our situation; He will not judge us as if we had no difficulties to overcome. What matters is the sincerity and perseverance of our will to overcome them.
Before we can be cured we must want to be cured. Those who really wish for help will get it; but for many modern people even the wish is difficult. It is easy to think that we want something when we do not really want it. A famous Christian long ago told us that when he was a young man he prayed constantly for chastity; but years later he realised that while his lips had been saying, ‘Oh Lord, make me chaste,’ his heart had been secretly adding, ‘But please don’t do it just yet.’ This may happen in prayers for other virtues too; but there are three reasons why it is now specially difficult for us to desire—let alone to achieve—complete chastity.
In the first place our warped natures, the devils who tempt us, and all the contemporary propaganda for lust, combine to make us feel that the desires we are resisting are so ‘natural’, so ‘healthy’, and so reasonable, that it is almost perverse and abnormal to resist them. Poster after poster, film after film, novel after novel, associate the idea of sexual indulgence with the ideas of health, normality, youth, frankness, and good humour. Now this association is a lie. Like all powerful lies, it is based on a truth—the truth, acknowledged above, that sex in itself (apart from the excesses and obsessions that have grown round it) is ‘normal’ and ‘healthy’, and all the rest of it. The lie consists in the suggestion that any sexual act to which you are tempted at the moment is also healthy and normal. Now this, on any conceivable view, and quite apart from Christianity, must be nonsense.
