 Hayek’s mentor, Ludwig Mises, stated the argument as follows in his treatise of economics, Human Action (1949, 92): “Economics is not about things and tangible material objects; it is about men, their meanings and actions. Goods, commodities, and wealth are all the other notions of conduct are not elements of nature; they are elements of human meaning and conduct. He who wants to deal with them must not look at the external world; he must search for them in the meaning of acting man.”
