Like Schutz, Hayek was a Misesian methodologist. The view that Hayek was a Misesian methodologist is probably a minority opinion. In spite of the work of Caldwell (1988, 1992a, 1992b), the most common view may still be that of Hutchison (1984) who argued that Hayek abandoned Misesian methodology in 1937. "Hayek I" was a follower of Mises, Hutichson argues, and "Hayek II" was a follower of Popper.² Hutchison's views are based on a reading of Mises that differs from my own. In Hutchison's reading, the essential feature of Mises' methodology is strict apriorism. Hutchison's principal text is Mises (1962). If Kurrild-Klitgaard (2001) is right, however, Mises (1962) is a "radicalized" apriorism not present in the 1930s.
