Abstract
The decline of communism in Eastern Europe in years 1989-1991 was a big surprise for Western Sovietology. The sudden disappearance of the object of research would undermine the reason of existence of the whole science. For this reason, in the first half of the 90s Western scientists tried to answer following question: why Sovietology was not able to predict the demise of communism. The purpose of my paper is not to make one more analysis of factors responsible for this failure of social sciences but reconstruction of theories which accurately predicted the demise of communism. It is possible to point out two scholars whopredicted the collapse of communism at the turn of the 70s and 80s. One of them is Randall Collins, an American sociologist who elaborated in 1978 Geopolitical Theory. The second of them is Leszek Nowak, Polish philosopher, who in 1979 elaborated theory of historical process – non-Marxian historical materialism. In the last part of my paper I compare these two theories. Despite obvious differences, these theories share striking similarities: model status, antagonistic vision of society, grand scope of applicability and belonging to the periphery rather than to mainstream of social sciences. Maybe, this last feature is one of the necessary conditions of making accurate predictions in social and historical sciences.
