This volume investigates the philosophical foundations of John Maynard Keynes' economic theory, specifically focusing on his conceptualization of probability, uncertainty, and social convention. The editors, Jochen Runde and Sohei Mizuhara, compile a collection of essays from prominent scholars to examine how these philosophical underpinnings inform Keynes' broader economic framework. By analyzing the evolution of his thought from his early work to his later contributions, the text argues that understanding Keynes requires a rigorous engagement with his views on epistemology and decision-making under conditions of ignorance.

Experts recognize this collection as a significant contribution to the secondary literature on Keynesian philosophy, often citing it for its depth in clarifying complex epistemological arguments. Readers frequently note the academic density of the prose, making it a resource primarily suited for graduate students and professional economists.
