Fire and Knowledge

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….

There is nothing to be ashamed 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.
