any impulse, presumably including the impulse to laugh. I mean no disrespect to Mr. Beresford; but my first duty, of course, is to my own psychological inside. And goodness knows what damage might not be done to the most delicate workings of my own mental apparatus (as Mr. Arnold Bennett called it) if I were to subject it to the sudden and violent strain of not smiling at the scientific theory which is attractive because it is sexual, or of forcing my features into a frightful composure when I hear of the spiritual necessity for the liberation of impulse. I am not quite sure how far the liberation of impulse is to be carried out in practice by its exponents in theory; I do not know whether it is better to liberate the impulse to throw somebody else out of an express train in order to have the carriage to oneself all the way; or what may be the penalties for repressing the native instinct to shoot Mr. Lloyd George. But obviously the greater includes the less; and it would be very illogical if we were allowed to chuck out our fellow-traveller but not to chaff him; or if I were permitted to shoot at Mr. George but not to smile at Mr. Beresford. And though I am not so serious as he is, I assure him that in this I am quite as sincere as he-is. In that sense I do seriously regret his seriousness; I do seriously think such seriousness a very serious evil. For some healthy human impulses are really the better for the relief by words and gestures, and one of them is the universal human sense that there is something comic about the relations of the sexes. The impulse to laugh at the mention of morality as "free" or of sex science as "attractive" is one of the impulses which is already gratified by most people who have never heard of psycho-analysis
