 Hayek’s growing frustration with the conversation among elite economists during the 1930s and 1940s was born out his utter surprise that the institutional wisdom passed down from classical political economists to the early neoclassical economists was being lost. He saw wanted to know why. He explored the rise of formalism and an emerging shift toward macro-theory emphasizing relationships between aggregate variables unconnected to the choices of individuals. To Hayek, these shifts were technical in part, but the technicality was masking (and partly driven by) a deeper philosophical shift from seeing the human condition as complex as a relatively simple machine that a good mechanic could tinker with and perfect. The whole idea of studying the human condition as a complex spontaneous order came to seem unscientific. Thus, in “The Use of Knowledge in Society”, Hayek says the maximizing and equilibrium thinking of mathematical economics “habitually disregards” essential parts of the phenomena to be explained, and in so doing “misleads some of our leading thinkers” (1944, 91).
