It was best presented perhaps by the distinguished doctor who wrote the article on these matters in that composite book which Mr. Wells edited, and called "The Great State." He said the doctor should no longer be a mere plasterer of paltry maladies, but should be, in his own words, "the health adviser of the community." The same can be expressed with even more point and simplicity in the proverb that prevention is better than cure. Commenting on this, I said that it amounted to treating all people who are well as if they were ill. This the writer admitted to be true, only adding that everyone is ill. To which I rejoin that if everyone is ill the health adviser is ill too, and therefore cannot know how to cure that minimum of illness. This is the fundamental fallacy in the whole business of preventive medicine. Prevention is not better than cure. Cutting off a man's head is not better than curing his headache; it is not even better than failing to cure it. And it is the same if a man is in revolt, even a morbid revolt. Taking the heart out of him by slavery is not better than leaving the heart in him, even if you leave it a broken heart. Prevention is not only not better than cure; prevention is even worse than disease. Prevention means being an invalid for life, with the extra exasperation of being quite well. I will ask God, but certainly not man, to prevent me in all my doings. But the decisive and discussable form of this is well summed up in that phrase about the health adviser of society. I am sure that those who speak thus have something in their minds larger and more illuminating than the other two propositions we have considered. They do not mean that all citizens should decide, which would mean merely the present vague and dubious balance. They do not mean that all medical men should decide, which would mean a much more unbalanced balance. They mean that a few men might be found who had a consistent scheme and vision of a healthy nation, as Napoleon had a consistent scheme and vision of an army. It is cold anarchy to say that all men are to meddle in all men's marriages. It is cold anarchy to say that any doctor may seize and segregate anyone he likes. But it is not anarchy to say that a few great hygienists might enclose or limit the life of all citizens, as nurses do with a family of children. It is not anarchy, it is tyranny; but tyranny is a workable thing. When we ask by what process such men could be certainly chosen, we are back again on the old dilemma of despotism, which means a man, or democracy which means men, or aristocracy which means favouritism. But as a vision the thing is plausible and even rational. It is rational, and it is wrong.
