海德格尔指出:“无”乃是最广泛、最深刻、最原始的问题,是形而上学的基本问题。传统形而上学只知问“有”而不知问“无”,而海氏认为只有在“无”中,存在者之可敞开状态才是可能的。中国古代的老子对有与无的关系进行了深入的探讨,老子的学说对海德格尔产生了深刻的影响,海氏关于“无”的论说是在老子学说的基础上形成的。 Heidegger pointed out: “Nothingness” is the most extensive, profound and primitive problem and the basic problem of metaphysics. In traditional metaphysics, only “yes” is known but “no” is not known. Hai believes that the openness of the being is possible only in “nothingness.” In ancient China, Lao Tzu conducted an in-depth discussion on the relationship between non-existence and non-existence. Lao-tzu’s theory had a profound impact on Heidegger. Hai’s theory of “no” was formed on the basis of Lao Tzu’s doctrine.
