从“理在事先”到“理在事中”：冯友兰逻辑分析法的根基转换

From “Idea before Things” to “Idea in Things”: The Foundational Shift in Feng Youlan’s Method of Logical Analysis

摘要: 中国现代哲学的发展，始终处于古今之变与中西之争的思想张力之中。冯友兰毕生以逻辑分析法为工具，致力于为传统哲学建构形式上的系统。这一努力的结晶便是其“新理学”体系。然而，这一以“理在事先”为核心预设的体系，呈现出一种深刻的悖论：先验的理世界越是精密，就越是悬浮于现实之上。正是在这一张力之中，经由对马克思主义哲学的接触与《实践论》的阐释，冯友兰逐步看清了自己哲学体系的病根不在分析工具本身，而在它所立足的哲学根基。由此，他将逻辑分析法的根基从先验的理世界转移到“理在事中”所指向的社会历史实践。基于这一转换，冯友兰的逻辑分析法不再服务于空灵玄妙的思辨体系，而是成为在“旧邦新命”的文化实践中辨析概念、阐明哲学系统的有力工具。从“理在事先”到“理在事中”的转变，不仅是冯友兰个人思想历程的转折点，更展示了中国现代哲学如何在与马克思主义的碰撞与融合中，完成了一次深刻的方法论重构。

Abstract: The development of modern Chinese philosophy has always been shaped by the intellectual tension between the ancient and the modern, as well as between Chinese and Western thought. Feng Youlan devoted his life to constructing a formal system for traditional Chinese philosophy through the method of logical analysis. The culmination of this endeavor was his “New Neo-Confucianism” system. However, this system, premised on the core presupposition of “Idea before Things”, revealed a profound paradox: the more refined the a priori realm of Ideas became, the more it floated away from concrete reality. It was within this tension that, after his engagement with Marxist philosophy and through his interpretation of On Practice, Feng Youlan gradually came to see that the source of his philosophical malady lay not in the tool of logical analysis itself, but in the philosophical foundation on which it rested. Consequently, he shifted the foundation of his logical analysis from the transcendent realm of Ideas to the socio-historical practice implied by “Idea in Things”. Following this shift, Feng’s logical analysis no longer served an ethereal and speculative system, but instead became a powerful tool for conceptual clarification and philosophical system-building within the cultural practice of “New Mission for the Ancient Nation”. The shift from “Idea before Things” to “Idea in Things” marks not only a turning point in Feng Youlan’s personal intellectual journey but also demonstrates how modern Chinese philosophy accomplished a profound methodological reconstruction through its encounter and integration with Marxism.
