As we move beyond civilization onto a more mature and more complicated culture level, we may have a workable system of social priorities, but does our oncoming stream of manpower have the interest, the imagination, the competence, the sense of social responsibility and the staying power necessary to arouse in a series of generations the will and determination to carry out social policy? Are the oncoming generations able and willing to shoulder the loads of clearing out the rubbish accumulated through ten centuries of western civilization, make effective use of science, technology _and_ available human capacity and move onward and forward to new levels of social achievement? We could develop a corps of socially responsible technicians as we have developed a corps of competent scientists and technicians in the field of natural science. In each field priorities are constantly changing. Each field is called upon to meet the changes by making corresponding changes in its personnel, its education and its apprenticeships. In addition to formal schooling and apprenticeship we have a vast network for the distribution of information and the formation of public opinion. The printing press, the camera and other means of communication determine the levels of information and the willingness of the public to keep abreast of the shifting social scene. A social structure resembles every other human meeting place--it tends to accumulate dead wood. There are two answers to this problem: periodic housecleaning, without fear or favor, together with careful scrutiny of the apprentices and other newcomers in the field. Every social group has its quota of defectives and delinquents--biological and social, physical, mental, emotional. Here the critical problem is where to draw the line. Perhaps the best general answer is to measure productiveness, including those who make a net contribution, including those whose presence is desirable and excluding undesirables. Again this involves periodic housecleanings. Throughout the past two centuries mankind has been confronted by an epoch-making, many sided development--the great revolution of 1750-1970. As I write, the great revolution is modifying the structure and functioning of human society and, consequently, the forces which condition, shape and, in large measure, determine the directions and channels in which humanity lives, moves and has its being.
