social nature of man meaning in Chinese

人的社会性

Before marx , materialism examined the problem of knowledge apart from the social nature of man and apart from his historical development , and was therefore incapable of understanding the dependence of knowledge on social practice , that is , the dependence of knowledge on production and the class struggle
马克思以前的唯物论，离开人的社会性，离开人的历史发展，去观察认识问题，因此不能了解认识对社会实践的依赖关系，即认识对生产和阶级斗争的依赖关系。
