本文通过对西方马克思主义学者拒斥自然辩证法这一现象进行反思,认为他们在辩证法问题上有两个基本的思维定式:一是辩证法只存在于人类社会历史之中,自在的自然世界不存在辩证法;二是辩证法不是科学意义上的认识论,历史的辩证规律是非决定论的。本文还从内在逻辑及认识论等角度对这两个定式作了分析与思考。 By reflecting on the rejection of dialectics of nature by Western Marxist scholars, this article argues that they have two basic formulas of thinking on dialectics: one is that dialectics exists only in the history of human society, and the other is that there is no dialectic in the natural world Second, dialectics is not epistemology in the scientific sense. The dialectic of history is inconclusive. This article also analyzes and thinks about these two formulas from the perspectives of internal logic and epistemology.
