理性服务方向与技术路径——李约瑟难题的一种技术哲学重释

中文摘要

“李约瑟难题”作为中国科技史与文明比较研究的核心命题，既有解释多从文化思想、制度结构、经济动力与科学范式等维度展开。本文认为，这些解释虽各有洞见，却未能充分回答一个更为基础的问题：为何理性能力在不同文明中会被稳定地引向截然不同的问题领域？为此，本文提出“理性服务方向”的分析框架，指出理性并非自带固定价值方向的纯然中性能力；其具体服务对象，始终受到情感价值目标、制度激励结构与现实实践需求的共同塑造。中国传统社会并非缺乏理性，而是理性长期被系统性地引向伦理、治理与秩序等“人”的领域；近代西方则在战争竞争、商业扩张与科学社团制度化的多重合力中，持续将理性引向自然、工程与机器等“物”的领域。通过对火药与印刷术两个经典案例的中西技术命运比较，本文揭示出“技术问题的选择机制”“资源投入的分配逻辑”与“制度化的反馈链条”是理解中西技术路径分化的关键机制。该框架不仅为李约瑟难题提供了新的解释维度，亦可为当下人工智能治理中的技术方向选择提供历史镜鉴与哲学反思

Abstract

As a core proposition in the history of Chinese science and technology and in comparative civilizational research, the "Needham Question" has existing explanations developed mainly from cultural thought, institutional structure, economic dynamics, and scientific paradigms. This paper holds that these explanations, though insightful, fail to adequately answer a more fundamental question: why is rational capacity stably directed, in different civilizations, toward radically different domains of problems? To this end, the paper proposes the analytical framework of "the service direction of reason," pointing out that reason is not a purely neutral capacity carrying a fixed value direction by itself; its concrete objects of service are always jointly shaped by affective value goals, institutional incentive structures, and practical needs of reality. Traditional Chinese society did not lack rationality, but rationality was for a long time systematically directed toward the domains of "persons" — ethics, governance, and order; modern Western society, under the multiple forces of war and competition, commercial expansion, and the institutionalization of scientific societies, persistently directed rationality toward the domains of "things" — nature, engineering, and machines. Through a comparative analysis of the divergent Chinese and Western fates of two classic cases, gunpowder and printing, the paper reveals that "the selection mechanism of technological problems," "the allocation logic of resource investment," and "the institutionalized feedback chain" are the key mechanisms for understanding the divergence of Chinese and Western technological paths. This framework not only provides a new explanatory dimension for the Needham Question, but also offers historical mirror and philosophical reflection for the choice of technological directions in contemporary artificial intelligence governance.
