“两个必然”与“两个决不会”是马恩运用唯物史观分析资本主义社会所得出的深刻论断。从内容看,“两个必然”揭示了资本主义社会发展的必然的趋势,“两个决不会”指出了这一趋势实现所需要的内在条件;从关系看,“两个必然”是资本主义社会中“两个决不会”运动的最终结果,“两个必然”中包含着“两个决不会”的思想。 “Two Necessity ” and “Two Never ” are the profound conclusions that Marx and Engels used to analyze the capitalist society with historical materialism. From the perspective of content, “two necessity ” reveals the inevitable trend of the development of capitalist society, “two will never ” pointed out the internal conditions needed to achieve this trend; from the relationship, “two The inevitable ”is the ultimate result of the“ two never-ends ”movement in capitalist society. The“ two inevitability ”contains the notion of“ two will never be. ”
