Since the middle ages, Aristotle has been hailed as the father of economics by economists, while classical scholars hold that he did no economics at all, only ethics. This book argues that Aristotle does develop a coherent theory of value, wealth, exchange, and money, which is strongly supported by his metaphysics. But its very metaphysical foundation make the theory impossible to assimilate to Neo-Classical economics or any other kind of economic thinking, and it therefore remains an ethical theory. On Aristotelian metaphysical principles, ethics and economics are competitors over the same ground--as rival sources of reasons for decision-making in tihe public realm, and they cannot be reconciled. "This is a delightful book..."-- The Review of Metaphysics It is argued here that Aristotle does develop a coherent theory of economic value, wealth, exchange, and money, but that this theory cannot be assimilated to what we call 'economics' because its metaphysical foundation is incompatible with the Human metaphysics on which economics is built.
