The class nature and people nature of Marxism are not parallel relationships in a parallel manner,but are manifested in the deepening and expansion of Marxist class nature,reflecting people nature.People nature,as a condition,is contained in the requirements of class liberation,which is the mechanism for the generation of the unity relationship between the two.The proletariat has its own unique class characteristics,revolutionary manifestations,and organizational forms,which serve as the basis for the interests of the proletariat and promote the manifestation of class nature in Marxism.At the same time,the proletarian liberation revealed by Marxism inherently embodies the human liberation direction of"eliminating all classes",thus reflecting the true people-oriented pursuit of human liberation.Marx thoroughly and completely revealed the realistic path of human liberation through his exposition of the progressive process of political liberation,economic liberation,social liberation,and labor liberation.This was the first time in the history of human concepts that the class foundation of ideology and the form of the people were historically and concretely unified.
