Abstract

This article is concerned with the structure of monetary denominations of economic value. Marx and Simmel analyze this structure by means of references to objects of mere catallactic validity. These objects are ontologically atypical insofar as they are particulars of the genus commodity. Understanding money through generic particulars elucidates the conceptual link between money as a unit of account and money as a means of payment. This initially perplexing idea captures a fundamental characteristic of money without committing to either a commodity theory or a claim theory of money. A modification of the notion ‘commodity’ allows for a conception of money as a generic particular that is consistent with contemporary accounts of money as abstract purchasing power residing in different forms of liabilities and claims denominated in a common quantitative scale.
