The central thesis of The Ontology and Function of Money: The Philosophical Fundamentals of Monetary Institutions is that, in order to evaluate monetary policy, one should have a clear idea about the characteristics and functions of money as it evolved and in its current form. Without an understanding of how money evolved as a social institution, what it is today, and what can be known about monetary phenomena, it is not possible to develop a meaningful ethics for money-to find what kind of institutional arrangements may be deemed good money for the kind of society we are in. And without such an understanding, one faces severe limitations in offering a normative position about monetary policy. This book is organized into parts on metaphysics, epistemology, ethics, and politics of money to facilitate the presentation of all the subjects discussed to an educated readership (and not necessarily just one with a background in economics).
