GRE写作论证论据素材大全—社会发展的三大理论

　　社会发展的三大理论
 

　　In the 19th century, three great classical theories of social and historical change were created: the sociocultural evolutionism, the social cycle theory and the Marxist historical materialism theory. Those theories had one common factor: they all agreed that the history of humanity is pursuing a certain fixed path, most likely that of the social progress. Thus, each past event is not only chronologically, but causally tied to the present and future events. Those theories postulated that by recreating the sequence of those events, sociology could discover the laws of history.
