The connection between static and dynamic forces in society became, once again, a topic for debate at the sociological congress held in Amsterdam in 1955. The reason for this renewed interest is not far to seek. Dynamic phenomena of great intensity force themselves on the observer of the contemporary scene. Within the Soviet sphere of influence, the structure of society is undergoing radical changes. At the same time, the Orient and all those areas said, not without reason, to be “developing,” are in the throes of modernization. And finally, even in countries ruled by liberalism and marked by stable institutions, the inner structure of such fundamental social concepts as “individual,” “family,” “stratification,” “organization” and “government” is rapidly being transformed. On the other hand, there are many countries in which society appears to be gravitating towards a static condition, characterized by Veblen more than fifty years ago, as a “new feudalism.” When all areas beyond the present-day borders of capitalism will have been industrialized, capitalism will no longer be able to rely on new resources elsewhere, and its economic expansion, which was once thought to be demanded by the very nature of the system, will have come to an end. Capitalism will then have to revert to simply reproducing itself. This prospect is reflected in our present-day culture. Thus, Olivier Messiaen, a composer of the group known as “La Jeune France,” said only recently, that the historical development of music had reached a ceiling beyond which no further development could be imagined; whether he was right or not, is not the point. What should be of most interest in a discussion of the conflict between static and dynamic forces, is the question which of these will prove to be the stronger; whether the trend of development prevailing since the Middle Ages will continue, or whether it will terminate in a state of paralysis of the kind that Himmler prophesied when he said that the Third Reich would last for ten or twenty thousand years, until the “end of modern times.” But before we can speculate about the outcome of the conflict between the static and dynamic, we must reflect on the ideas connected with them; otherwise it would be like trying to settle the course of world history by idly tossing a coin.
