More Heat Than Light is a history of how physics has drawn some inspiration from economics and also how economics has sought to emulate physics, especially with regard to the theory of value. It traces the development of the energy concept in Western physics and its subsequent effect upon the invention and promulgation of neoclassical economics. Any discussion of the standing of economics as a science must include the historical symbiosis between the two disciplines. Starting with the philosopher Emile Meyerson's discussion of the relationship between notions of invariance and causality in the history of science, the book surveys the history of conservation principles in the Western discussion of motion. Recourse to the metaphors of the economy are frequent in physics, and the concepts of value, motion, and body reinforced each other throughout the development of both disciplines, especially with regard to practices of mathematical formalisation. However, in economics subsequent misuse of conservation principles led to serious blunders in the mathematical formalisation of economic theory. The book attempts to provide the reader with sufficient background in the history of physics in order to appreciate its theses. The discussion is technically detailed and complex, and familiarity with calculus is required.

"Intellectual stars of his magnitude (as opposed to scientific stars) don't come along very often....in More Heat Than Light...he states a challenge that is going to haunt economists for years....Mirowski and his ideas are about to move out of the history of economics into the wider stream." David Warsh, The Boston Globe

"No previous writer has made such a sustained and determined effort to explore the undeniably important conceptual links between economics and physics; and this alone is a landmark contribution of importance to all economists, not merely to specialist historians of the discipline." Kyklos
