Abstract

The ethical authority carried in the conventions of fairness and human well-being has been widely adopted under the idea of “moral economy,” forming an eclectic and interdisciplinary debate. Significant, though external to this debate, is a corpus of medieval thought which exhibits a fundamental interest in legitimate market protocols, and the political rights and obligations of agents in relation to the common good of the community. This article asserts the imperative status of a customary basis for understanding not just the analytic version of moral economy but the legacy contained in what might be termed the “the moral economy of Aquinas.”
