恩格斯晚年的一个重要贡献,是反复强调、精辟概括和深入阐述了“马克思主义不是教条”这一科学命题。恩格斯在不同情况下,提出了四种不同的命题形态:“马克思主义不是教条,而是对历史过程的阐明”;“马克思主义不是教条,而是发展着的理论”“;马克思主义不是教条,而是研究的方法”“;马克思主义不是教条,而是行动的指南”。这些角度不同的表述分别包含着特定的内容,把这些内容揭示出来,有助于我们更加全面科学地理解和把握“马克思主义不是教条”这一科学论断。 Engels made an important contribution to his later years by repeatedly emphasizing and elaborating on the scientific proposition that “Marxism is not dogma.” Under different circumstances, Engels proposed four different forms of propositions: “Marxism is not a dogma, but an explanation of the historical process.” “Marxism is not a doctrine, but a theory of development.” Marxism is not a dogma, but a research method. “Marxism is not a dogma, but a guide to action.” These different perspectives contain specific contents respectively. By disclosing these contents, it is helpful for us to understand and grasp more comprehensively and scientifically the scientific thesis that “Marxism is not dogma.”
