The vast and powerful machinery developed to meet the needs of Scientific Management in industry, government, and education may make it possible to initiate and control the operation of the natural laws of change. Side by side with the direct control of character, belief, and action, large-scale experiments in eugenics may proceed. Such experiments would not demand the clumsy expedient of the Act of Parliament. The triple control will provide adequate means for eliminating the intractable factors in the situation. Perhaps the constitution of the United States of America provides the most promising machinery at present for large-scale sociological experiment. These States, moreover, are fortunate in the character of their population. But whether by education or by eugenic control man himself will change. Physically, by a process of atrophy (at which Dr Schiller will not, I trust, demur), he may consist chiefly in a head from which will depend a mass of atrophied limbs. He will presumably be more or less permanently mounted upon a compact automobile, travelling by road or by air. No doubt a submarine attachment will be available to facilitate his morning bath.[9] But it is not with his appearance that we are here concerned. What is the future of his mind? [9] But on all questions relating to our mechanical future I must refer the reader to Professor A. M. Low, to whose works _The Future_ and _Wireless Possibilities_ I myself am chiefly indebted in this respect. There are interesting possibilities in the sphere of sense alone. Some of our present senses, such as taste or smell, may disappear altogether. More and more we seem to depend upon purely visual cues. On the other hand, vision and hearing may be considerably augmented. Even though they be supplemented by microphones and microscopes, we always strive to see and hear a little more than the best of instruments allows. If, after all, the biological vitalists are right, so long as we are interested in the constitution of matter there is a motive for further variation. But, as Professor Low points out, our æsthetic susceptibilities will have to be modified on the way. When we first begin to perceive the fauna in the cheese and the microbes on our walls, and when, like the birds, we go into the country to listen to the worms, we shall have to revise our values. Our poets, too, will find new themes to sing. Memory, even more than sense, suggests many possibilities of development. By hypnotism, or by the natural working of the unconscious mind, it is said that we can recall even the earliest events of life. Soon, perhaps, this power will be under conscious control, and the autobiographers will have their millennium too. But, quite apart from this, new methods of education and a little Scientific Management would enable us, even now, to do much more with our memories through the powers we already possess.
