在德国哲学的发展史上,费尔巴哈的最大功绩就在于他恢复了唯物主义的权威,结束了自康德以来的哲学革命,从而为1848年资产阶级革命做了思想准备。他在批判地改造了黑格尔思维与存在同一学说的基础上,提出了自己的认识论的基本命题:人是思维与存在统一的基础和主体。本文分析了费尔巴哈认识论的合理性及人本主义局限性。 In the history of German philosophy, Feuerbach’s greatest achievement is that he restored the authority of materialism, ended the philosophical revolution since Kant, and thus made ideological preparations for the bourgeois revolution in 1848. Based on the critical transformation of Hegel’s thinking and the existence of the same doctrine, he proposed his own basic proposition of epistemology: Man is the basis and subject of the unity of thinking and existence. This article analyzes Feuerbach’s epistemological rationality and humanistic limitations.
