Instead of seeing in the odd cases of the cow’s tongue or the bleating sheep the peril of their past generalizations, they will see them only as starting points for new generalizations. They will get yet another theory out of it. And they will begin acting on the theory long before they have done thinking about it. They will start out with some new and crude conception that sculpture has made children scream or that nursery rhymes have made children sleepless; and the thing will be a clause in a programme of reform before it has begun to be a conclusion in a serious study of psychology. That is the practical problem about modern liberty which the critics will not see; of which eugenics is one example and all this amateur child-psychology is another. So long as an old morality was in black and white like a chess-board, even a man who wanted more of it made white was certain that no more of it would be made black. Now he is never certain what vices may not be released, but neither is he certain what virtues may be forbidden. Even if he did not think it wrong to run away with a married woman, he knew that his neighbours only thought it wrong because the woman was married. They did not think it wrong to run away with a red-haired woman, or a left-handed woman, or a woman subject to headaches. But when we let loose a thousand eugenical speculations, all adopted before they are verified and acted on even before they are adopted, he is just as likely as not to find himself separated from the woman for those or any other reasons. Similarly there was something to be said for restrictions, even rather puritanical and provincial restrictions, upon what children should read or see, so long as they fenced in certain fixed departments like sex or sensational tortures. But when we begin to speculate on whether other sensations may not stimulate as dangerously as sex, those other sensations may be as closely controlled as sex. When, let us say, we hear that the eye and brain are weakened by the rapid turning of wheels as well as by the most revolting torturing of men, we have come into a world in which cart-wheels and steam-engines may become as obscene as racks and thumbscrews. In short, so long as we _combine_ ceaseless and often reckless scientific speculation with rapid and often random social reform, the result must inevitably be not anarchy but ever-increasing tyranny. There must be a ceaseless and almost mechanical multiplication of things forbidden. The resolution to cure all the ills that flesh is heir to, combined with the guesswork about all possible ills that flesh and nerve and brain-cell may be heir to--these two things conducted simultaneously must inevitably spread a sort of panic of prohibition. Scientific imagination and social reform between them will quite logically and almost legitimately have made us slaves. This seems to me a very clear, a very fair and a very simple point of public criticism;
