The Aristotelian Theory of Economic Justice Revisited
重新审视亚里士多德在《尼各马可伦理学》和《政治学》中的经济正义理论，指出商品的使用价值不可通约而交换价值可通约，并借助休谟的惯例概念来理解亚里士多德理论中的“惯例”含义。
Aristotle develops his theoryof economic justice in Nicomachean Ethics and Politics. The theoryis interesting because his discussion of economic justice is connected to his larger concern about the relationship between the commensurable and incommensurable. Commodities are mutually incommensurable from the viewpoint of their use value but commensurable from that of exchange value. Theyare reduced to be mutuallycommensurable on the basis of "need (chreia)". The medium of this quantitative comparison is money, which is introduced by "convention (hypothesis)". There have been various interpretations concerning the meaning of "need", but little discussion about the meaning of "convention". I propose in this paper that Hume's analysis of convention in The Treatise of Human Nature could be profitably made use of for understanding the Aristotelian idea of convention.
