This book focuses on the analysis of the Evolutionary Theory of Social Institutions by the Austrian School of Economics, primarily those in the realms of economics and law, building upon the work started by C. Menger. It's an interdisciplinary work that intertwines contributions from various social sciences (History, Economics, Law, Philosophy, etc.) to provide a comprehensive and integrated view of this complex subject. The book begins by exploring the influential schools of thought on the Austrian School's authors, followed by chapters on methodology, starting with the Theory of Human Action and Exchange Relations (with input from authors like L. von Mises or I.M. Kirzner), culminating in the study of social institutions. Prologue: An Overview Introduction: Setting the Stage Part I: Origins and Birth of Evolutionary Perspectives in Social Sciences Part II: Methodology of the Austrian School Part III: The Austrian School's Analysis of Key Social Institutions
