本文主要研究了波普尔和哈耶克对建构论者提出的乌托邦式的理想社会进行的批判。指出其理性主义的实质是非理性主义,其历史主义是圣人主义,其自由会导致奴役,其道德的激情会造成不道德的后果。并以此说明,人类不可能一劳永逸地到达天堂式的理想社会,人类的历史就是从不完善走向相对完善的过程。 This paper mainly studies Popper and Hayek’s criticism of the utopian ideal society proposed by constructivists. It points out that the essence of rationalism is non-rationalism. Its historicism is saintism. Its freedom will lead to enslavement. The moral passion will cause unethical consequences. And to show that it is impossible for mankind to reach paradise-like ideal societies once and for all, the history of mankind is a process from imperfection to relative perfection.
