In the process of leading the international communist movement,Marx and Engels faced the profound influence of social revolution and multi-social thoughts caused by the development of capitalism.They always stood at the historical height and the forefront of the times with their attention attached to and study the peasant issues,on the basis of the need to provide scientific theoretical guidance for the workers’ movement and the revolutionary allied forces.Marx and Engels insisted on the connection between theory and practice,the unity of materialism and dialectics,the combination of principle and flexibility,the principle of complementing macro and micro analysis,and the features of peasantry class,personality characteristics,revolutionary nature,political attitudes and history of peasants and other in-depth analysis being accomplished and put forward practical and feasible joint measures to form a peasant thought with great scientific connotation.This idea is still of important value for the implementation of the rural revitalization strategy by our party in the new era and the proper resolution of the “three rural issues”. 展开更多

This year marks the 200th anniversary of the birth of the great proletarian revolutionary mentor Engels,and the theoretical community has once again started a wave of research on his thought.On the basis of Hegel’s dialectic,Engels inherited and developed Marx’s dialectic,and founded the materialist dialectic,which he called“the best tool and the sharpest weapon”.However,the relationship between Engels’materialist dialectics and Marx’s dialectics has been debated for more than a hundred years in the theoretical circles both at home and abroad,and it is of great significance to correctly summarize and elaborate the domestic and international views in order to clarify the internal logic and truth of Engels’materialist dialectics. 展开更多

Study of the classic texts of Marx and Engels should employ two perspectives: Marxist philosophical history and Marxist philosophical principles. The two cannot be separated, still less contradictory. In dealing creatively with these classic works, we must firmly uphold the methodology of historical materialism, read them in accordance with the authors' original intentions and approach them creatively. We need to oppose research styles that place undue emphasis on the researcher's own interpretations and constructions. Research on Marxist philosophy should develop on the basis of respect, study and correct understanding of Marx and Engels' classic works; different readings of these texts must not be allowed to construct a pluralist Marxism. This is of great importance for consolidating the leading position of Marxism in the sphere of ideology. 展开更多
