But these are the mere opening requirements of this hope of mine of a quickened social consciousness among the more fortunate and leisurely section of the community. I believe that much profounder changes in the conditions of labour are possible than those I have suggested. I am beginning to suspect that scarcely any of our preconceptions about the way work must be done, about the hours of work and the habits of work, will stand an exhaustive scientific analysis. It is at least conceivable that we could get much of the work that has to be done to keep our community going in far more toil-saving and life-saving ways than we follow at the present time. So far scientific men have done scarcely anything to estimate under what conditions a man works best, does most work, works more happily. Suppose it turns out to be the case that a man always following one occupation throughout his lifetime, working regularly day after day for so many hours, as most wage-earners do at the present time, does not do nearly so much or nearly so well as he would do if he followed first one occupation and then another, or if he worked as hard as he possibly could for a definite period and then took holiday? I suspect very strongly, indeed I am convinced, that in certain occupations, teaching, for example, or surgery, a man begins by working clumsily and awkwardly, that his interest and skill rise rapidly, that if he is really well suited in his profession, he may presently become intensely interested and capable of enormous quantities of his very best work, and that then his interest and vigour rapidly decline. I am disposed to believe that this is true of most occupations, of coal mining or engineering, or bricklaying or cotton-spinning. The thing has never been properly thought about. Our civilisation has grown up in a haphazard kind of way, and it has been convenient to specialise workers and employ them piecemeal. But if it is true that in respect of any occupation a man has his period of maximum efficiency, then we open up a whole world of new social possibilities. What we really want from a man for our social welfare in that case is not regular continuing work, but a few strenuous years of high-pressure service. We can as a community afford to keep him longer at education and training before he begins, and we can release him with a pension while he is still full of life and the capacity for enjoying freedom. But obviously this is impossible upon any basis of weekly wages and intermittent employment; we must be handling affairs in some much more comprehensive way than that before we can take and deal with the working life of a man as one complete whole.
