Popper's methodological individualism and the social sciences. Popper's philosophy of social sciences poses a dilemma that arises out of the two theses of methodological individualism and situational logic. In order to find a way out of this dilemma, one must raise the question concerning the epistemological and methodological status of the `laws' of the human sciences. There are indeed `rules' from which human actions depart mostly to a negligible extent, but they remain valid or stay in effect without exception only (...) as far as they are not re-evoked or re-emerge in the consciousness of the agents. The element of truth of methodological individualism lies in the person's capacity to revoke, in principle, the validity of the rules concerning oneself. Situational logic and methodological individualism can thus be reconciled. (shrink)
