本文着重探讨邓小平对马克思主义认识论的主要贡献：通过改革，旨在解放作为认识和实践主体的人民群众；把辩证唯物主义认识论路线具体化为推进改革开放“走一步，看一步”的方针；对党的实事求是的思想路线进一步明确“实践标准”，并把解放思想和实事求是辩证地统一起来。 This article focuses on Deng Xiaoping’s major contribution to Marxist epistemology: Through the reform, aimed at the liberation of the masses as the main body of understanding and practice; the dialectical materialist epistemology line as the “one step, one step” approach to promote the reform and opening up; The Party’s ideological line of seeking truth from facts further clarifies the “standard of practice” and dialectically unifies the emancipation of the mind and seeking truth from facts.
