ABSTRACT
In this chapter, I will first argue that, even from the standpoint of Hayek’s proper epistemological and political vision, there is a serious logical inconsistency in his conceptual position when he opposes the Cartesian attitude. The logic, which governs the competitive market as a spontaneous order requires the Cartesian radical doubt as its precondition. The Cartesian doubt allows the individual to emancipate itself from the links and restrictions of tradition; it constitutes the logical precondition of the ‘open society’ as Hayek or Popper understand it.
