经济人的“知识骚乱”——经济人假设知识论转向史考察

历史地看,现代经济学策动过两场理性主义运动:一是古典理性主义运动,它根源并隶属于苏格兰启蒙哲学传统;二是新古典理性主义运动,它根源并隶属于法国启蒙哲学传统。这说明,现代经济学在其发展的不同阶段曾经分别隶属于两种不相容的理性哲学传统,也就是说,现代经济学的理性经济人这一核心假设曾经经历了一次"知识论转向":从原生态经济人的有限理性和有限知识传统转向了新古典经济人的完备理性和完备知识传统。对于这次"知识论转向"所产生的深远影响及其理论后果,哈耶克形象而准确地称其为"一场知识骚乱"。揭示经济人的这个"知识转向史",特别是这场"知识骚乱"的性质,是深入解释现代经济学发展演变逻辑的关键一环。

The “Knowledge Riots" of Economic Man——Studying on the Knowledge Transformation of Assumption of Economic Man

Historically, modern economics has instigated two kinds of rationalism movements: One was the classical rationalism movement, and it was rooted in the Scottish Enlightenment philosophical traditions; The other was the neo-classical rationalism movement, and it was rooted in the French Enlightenment philosophical traditions. This shows that Assumption of Economic Man has experienced a "Knowledge Transformation":From the limited knowledge of the classical economic man to completed knowledge of neo-classical economic man. Hayek accurately regarded it as The "Knowledge Riots" of Economic Man.
