This volume presents ten thought-provoking essays exploring issues in the philosophy of finance that are crucial for the economy and society. They also show the mutual relations and benefits between finance and philosophy. These issues include the link between financial systems and climate change, the ontologies of finance that are essential for market design, the role and effect of AI in the financial systems, the nature and prospects of money and their digital version, methodological problems in the use of models and mathematics in the financial world, and critical discussions of some of the main theories on financial systems, like the efficient market hypothesis. As this volume covers a wide array of topics whilst still forming a coherent whole, it is of interest to philosophers of finance, philosophers of science, epistemologists, and philosophers of economics, as well as to scientists and practitioners interested in the debates over methodological, ontological, epistemological as well as ethical issues in finance.
