2F.A. Hayek’s methodological U-turn reconsidered in light of his concept of social facts

The purpose of this chapter is to disprove the thesis of the U-turn. I shall show that even right at the start of his career, Hayek had different methodological ideas from those of his mentor Mises. This argumentation is sufficient for my objective, but it is rather unsatisfactory if we want to gain a better understanding of the development of Hayek’s thought. I will defend the thesis that he derived his ideas on the philosophy of science from Mach and the logical positivists.
