16 DANGEROUS THOUGHTS To-day scientific knowledge offers us the possibility of a new plan of social living more akin to the Utopia of a William Morris or an Edward Carpenter. Mobile power, aviation, and electrical communications make it possible to distribute population at a high level of productive capacity without the disabilities of cul- tural isolation. A high potential of leisure and creature comforts no longer demands the beehive pattern of social living. Co- operative organization in the age of hydroelectric power, of light metals, of artificial fertilizers, and of applied genetics offer us new instruments of manufacture, new means of transport, and new means of communications, l>oth to restore the serenity of small community life and to promote a lively sympathy with folk in other lands. Broadcasting has now brought the cultural benefits of travel to the bedside, and scientific horticulture offers us a programme of bio-esthetic planning which may prove more congenial to basic human needs than the spectacle of a sixpenny store building. The straphanging multitudes of our great cities need circuses as well as bread. It is no longer Utopian to ask what sort of circus human nature demands. The Thifd Reich has given its own answer. The answer is Jew-baiting, war, and neopagan weddings. The revolt against the beehive city of competitive industrialism has already become a retreat into barbarism. The rretreat will continue unless science can foster a lively recognition of the positive achievements of civilization by reinstating faith in a future of constructive effort. It will not be arrested by old-school- tie Socialists fresh from the exploits of the Oxford Union or by a radical intelligentsia whose social culture is a judicious blending of flexions and genuflexions. Seventy years ago it was still possible to discuss whether poverty is morally tolerable or materially inevitable. It was still possible to discuss whether war is spiritually edifying or socially escapable. All this is changed. Poverty in the sense in which it was then defined, the sense in which the word is intelligible to the social biologist, is not materially inevitable. The only obstacle to removing it is lack of social initiative. War is not a moral
