In the article written in September 1981 r. the author undertakes an attempt of describing and explaining the processes of change at the turn of the 1980s in Poland, - which are called 'revival movement' in the text - by the application of the one of sociological middle range theories, i.e. the collective behavior theory, social movements theory in particular. Middle range theories posses the generalizing potential, while at the same time they maintain the ability of explaining concrete social processes. The author suggest that the role of theory is to supply the tools for describing the processes of change and explaining their mechanisms. According to the author the possibilities of making predictions are limited in Polish case, however. After drawing three pairs of oppositions that allow describing the revival movement analytically (genetic-current; group-process related; immanent-contextual), the author draws eight hypothesis: (1) sequential accumulation hypothesis; (2) dissociation hypothesis; (3) tolerance threshold hypothesis; (4) diffusion hypothesis; (5) system emergence hypothesis; (6) axiological consensus hypothesis; (7) actions rationalization hypothesis; (8) society's new polarization hypothesis. These hypotheses are designed as the basis for the theory of revival movement.
