Psychology vs. Praxeology

Jörg Guido Hülsmann

“Mises’s exposition of economic science differed decisively from all modern authors in that it drew a sharp line between praxeology and psychology. This has remained a defining feature of the works of his disciples.

Mises did not contest that the psychological background of a person, his worldview, knowledge, conscious motivations, subconscious urges, and so on have an immediate impact on his behavior. Neither did he ignore the important psychological problems that his friend F.A. Hayek began to stress in those years, in particular, that of knowledge acquisition. Mises’s point was that there were also laws of human behavior that exist in complete independence of these psychological dispositions.”
