Abstract: | Social movements come into existence only on the basis of certain preconditions. The concurrence of distinct factors on the levels of individual experience, collective framing and societal structure favour the emergence and stabilization of social movements. Drawing on a model that links these three levels with aspects of problematization, mobilization and stabilization, we argue that there is a growing probability for social movements to come into existence. This probability stems mainly from a set of macro-structural trends and their problematic effects that can be interpreted in terms of differentiation theory. Instead of encompassing and stable class movements as represented, for example, by the labour movement, we expect a multitude of more situationally bound movements that vary considerably in their themes, social bases and forms. It is precisely this heterogeneity of movements that is an enduring feature of contemporary Western societies. |
