A great deal of work is sedentary, and most manual work exercises only a few specialized muscles. When crowds assemble in Trafalgar Square to cheer to the echo an announcement that the government has decided to have them killed, they would not do so if they had all walked twenty-five miles that day. This cure for bellicosity is, however, impracticable, and if the human race is to survive – a thing which is, perhaps, undesirable – other means must be found for securing an innocent outlet for the unused physical energy that produces love of excitement. This is a matter which has been too little considered, both by moralists and by social reformers. The social reformers are of the opinion that they have more serious things to consider. The moralists, on the other hand, are immensely impressed with the seriousness of all the permitted outlets of the love of excitement; the seriousness, however, in their minds, is that of Sin. Dance halls, cinemas, this age of jazz, are all, if we may believe our ears, gateways to Hell, and we should be better employed sitting at home contemplating our sins. I find myself unable to be in entire agreement with the grave men who utter these warnings. The devil has many forms, some designed to deceive the young, some designed to deceive the old and serious. If it is the devil that tempts the young to enjoy themselves, is it not, perhaps, the same personage that persuades the old to condemn their enjoyment? And is not condemnation perhaps merely a form of excitement appropriate to old age? And is it not, perhaps, a drug which – like opium – has to be taken in continually stronger doses to produce the desired effect? Is it not to be feared that, beginning with the wickedness of the cinema, we should be led step by step to condemn the opposite political party, dagoes, wops, Asiatics, and, in short, everybody except the fellow members of our club? And it is from just such condemnations, when widespread, that wars proceed. I have never heard of a war that proceeded from dance halls.
