In our introductory lecture, we explore the ubiquitous nature of finance in modern life, from everyday transactions to complex market operations. Dr. Brook delves into the paradoxical relationship between society's dependence on financial systems and the widespread distrust of financial institutions, highlighting how this tension has led to extensive regulation that potentially hampers economic efficiency. Finally, he outlines upcoming topics including money, banking, stock markets, and the future of finance.

In lecture two, Dr. Brook discusses the historical evolution of money and interest, tracing their development from ancient barter systems to the use of precious metals like gold and silver as currency. We examine the concept of usury—lending with interest—and how its prohibition in Christianity and Islam contrasted with the role of Jewish moneylenders in medieval Europe. Through this lens, the lecture highlights the complex ties between religion, economics, and the emergence of modern banking practices.

In lecture three, we continue our exploration of the historical evolution of banking and monetary systems, tracing the shift from medieval Christian opposition to usury to more flexible attitudes during the Renaissance and Reformation. The lecture follows the development of modern banking practices—from goldsmiths and fractional reserve banking to the rise of central banks and fiat currency. It concludes by examining the Federal Reserve’s role in contemporary monetary policy and the ongoing debate between government control and market-based alternatives.
