对话辩证法与马克思主义辩证法是从朴素到科学、从直观到深入的一种演变过程。一种是早期辩证法思想的萌芽,一种是辩证法思考发展的高级形态。虽然两者产生于不同的历史语境,但在对形而上学的批判和动态矛盾观上仍有相通之处。此外,对话辩证法作为辩证法思想的萌芽,了解其蕴含着的辩证法原始内涵,也可以帮助更好地理解马克思主义辩证法。故本文以选取《会饮篇》作为思考文本来论述对话辩证法的逻辑核心,通过系统比较两种辩证法在认识论方法、本体论基础、实践导向等方面的异同,揭示了西方古典哲学与现代马克思主义哲学在辩证思维上的联系与区别。The transition from dialogic dialectics to Marxist dialectics represents an evolution from nascent to scientific, and from intuitive to profound methodologies. While the former embodies the early germination of dialectical thought, the latter manifests as an advanced form of dialectical reasoning. Although originating from different historical contexts, they share similarities in their critique of metaphysics and the perspective of dynamic contradiction. Moreover, as the rudiment of dialectical thought, understanding the primordial dialectical essence embedded in dialogic dialectics can enhance our comprehension of Marxist dialectics. This paper selects “Symposium” as the text for contemplation to elaborate on the logical core of dialogical dialectics. By systematically comparing the similarities and differences between the two dialectics in terms of epistemological methods, ontological foundations, and practical orientations, it reveals the connections and distinctions between Western classical philosophy and modern Marxist philosophy in dialectical thinking.
