Marx adhered to the world history position, but in the course of formulating his theory of the Asiatic mode of production he moved from universal history to a particularistic view of history; whereas the shift from the ＂Russian path＂ and ＂Russian way＂ provided by the Russian revolution to Stalin＇s doctrine of the ＂five forms＂ of social development represented a return from particularistic to universal history. In developing a Chinese view of history, three elements cannot be overlooked： the Chinese pattern of historical development and China＇s present development experience; Marx＇s theory of social forms and his thoughts on Oriental society in his later years; and the ＂Russian path＂ and ＂systemic transformation＂ launched by the October Revolution.展开更多
