This book explores the deep meaning-the nature or essence-of the economy and its fundamental components. As a monograph on the philosophy of the economy and economics, it deduces the metaphysical nature of these two, going step by step from more general to more specific realities to finally arrive at the adequate features of the economic sciences and their methods. It builds on a largely Aristotelian approach, but also draws extensively from modern scholarship in the area. Usefully and pertinently, the book covers both general aspects of the economy and particular historically specific features. Among the important topics covered in the book are the meanings of the economy, the nature and role of economic agents, the nature of the macroeconomy, the nature and role of money, and so on. The book concludes with chapters on the nature of economics itself and its methodologies.
