关于社会历史发展的动力问题,是唯物史观研究的重要问题,但是,对于社会生活中的精神因素和历史“合力”思想的重视不够。对于恩格斯“历史合力”思想有待于进一步地深入研究,这在社会发展进入知识经济的时代尤为重要。在精神因素的作用问题上,我们也曾有过失误。因此,重视社会发展中精神因素的作用问题,具有理论和现实意义。 The motive force for the development of social history is an important issue in the study of historical materialism. However, the emphasis on the spiritual elements in social life and the historical “synergy” is not enough. For Engels “history together force” needs to be further in-depth study, which is particularly important in the era of social development into the knowledge economy. We have also made mistakes in the role of mental factors. Therefore, paying attention to the role of spiritual factors in social development has theoretical and practical significance.
