juries) who cannot see the difference between opinion and slander. And it is the highly placed and highly paid experts who have brought in the first Eugenic Law, the Feeble-Minded Bill--thus showing that they can see no difference between a mad and a sane man. That, to begin with, is the historic atmosphere in which this thing was born. It is a peculiar atmosphere, and luckily not likely to last. Real progress bears the same relation to it that a happy girl laughing bears to an hysterical girl who cannot stop laughing. But I have described this atmosphere first because it is the only atmosphere in which such a thing as the Eugenist legislation could be proposed among men. All other ages would have called it to some kind of logical account, however academic or narrow. The lowest sophist in the Greek schools would remember enough of Socrates to force the Eugenist to tell him (at least) whether Midias was segregated because he was curable or because he was incurable. The meanest Thomist of the mediæval monasteries would have the sense to see that you cannot discuss a madman when you have not discussed a man. The most owlish Calvinist commentator in the seventeenth century would ask the Eugenist to reconcile such Bible texts as derided fools with the other Bible texts that praised them. The dullest shopkeeper in Paris in 1790 would have asked what were the Rights of Man, if they did not include the rights of the lover, the husband, and the father. It is only in our own London Particular (as Mr. Guppy said of the fog) that small figures can loom so large in the vapour, and even mingle with quite different figures, and have the appearance of a mob. But, above all, I have dwelt on the telescopic quality in these twilight avenues, because unless the reader realises how elastic and unlimited they are, he simply will not believe in the abominations we have to combat. One of those wise old fairy tales, that come from nowhere and flourish everywhere, tells how a man came to own a small magic machine like a coffee-mill, which would grind anything he wanted when he said one word and stop when he said another. After performing marvels (which I wish my conscience would let me put into this book for padding) the mill was merely asked to grind a few grains of salt at an officers' mess on board ship; for salt is the type everywhere of small luxury and exaggeration, and sailors' tales should be taken with a grain of it. The man remembered the word that started the salt mill, and then, touching the word that stopped it, suddenly remembered that he forgot. The tall ship sank, laden and sparkling to the topmasts with salt like Arctic snows; but the mad mill was still grinding at the ocean bottom, where all the men lay drowned. And that (so says this fairy tale) is why the great waters about our world have a bitter taste. For the fairy tales knew what the modern mystics don't--that one should not let loose either the supernatural or the natural. CHAPTER IV
