This collection of interdisciplinary essays is the first to investigate how images in the history of the natural and physical sciences have been used to shape the history of economic thought. It documents the extent to which scholars have drawn on physical and natural science to ground economic ideas and evaluate the role and importance of metaphors in the structure and content of economic thought. These range from Aristotle's discussion of the division of labor, to Marshall's evocation of population biology, to Hayek's dependence upon evolutionary concepts, and more recently to neoclassical economists' invocation of chaos theory.
