It is reassuring and encouraging to compare the rise of nationalism and Europeanism during the past thousand years with the rise of planetism and worldism from 1450 to 1970. The development of nationalism and Europeanism is still incomplete, but the drive in that direction has thus far survived the fragmenting forces of self-determination and political independence which have played so vital a role in human society since the beginning of the present century. Europeanization is still a dream rather than a reality. The forces of regionalism, nationalism, and separatism still dominate European life. But the ideology and techniques of Europeanization are widely recognized, accepted and put into practice. The development of worldism seems to be following a parallel course. Consequently, wisdom, foresight, and the acceptance of change as a major factor in all social relationships seem to justify our assumption that sooner or later man's survival on the planet will depend on a degree of worldist thinking, association and institutionalism that will guarantee the preservation of order and decency at the planetary level. Since conformity implies and involves a will to diversity, measures to establish and maintain order and peace would include the widest possible latitude and the utmost effort to encourage the greatest possible diversity at regional, national and local levels. Thus diversity would become a virtue in much the same sense that conformity became a virtue in bourgeois Europe toward the end of the last century and in North America during the Joseph MacCarthy period. Through the past dozen years American youth has reversed the trend, adopting a permissiveness under which the sky is the limit in language, clothing, sexual conduct and professional choice and behavior. Non-conformity is all very well as protest against super-conformity, but it fails utterly to meet the basic need of the 1970's for a mass movement away from the institutions and practices of civilization, plus a disciplined and purposive mass determination to assume attitudes, adopt practices and establish institutions leading beyond civilization to a world culture pattern which insists upon conformity up to a point necessary for survival and social advance, and beyond that point, a diversity--including recognized and organized opposition at the planetary center. At the same time there must be a degree of regional and local diversity that will provide for the utmost independence, self-confidence, self-expression and regional and local self-determination compatible with the basic principle: to each in accordance with need.
