Marx's value forms and Hayek's rules: a reinterpretation in the light of the dichotomy between physis and nomos
论证马克思和哈耶克都反对自然与约定的二分法，并提出整合两者的概念：马克思的价值形式和哈耶克的规则，它们既非纯粹自然也非纯粹人为，而是“社会自然”的。
This paper argues that both Marx and Hayek objected to the dichotomy between physis and nomos, and offered concepts which integrate, or mediate between, the two. Marx's value forms and Hayek's rules aim to grasp something neither purely natural nor purely artificial or social, but 'socially natural'. Value forms and rules are natural in the sense that they pre-exist agents and are taken by agents as given. On the other hand, forms and rules are social in that production relations or spontaneous order are reproduced as the unintended consequences of agents' using forms or following rules. Thus value forms and rules stand as links between agents and production relations or spontaneous order. Copyright 2002, Oxford University Press.
