Politics, Epistemology and Method: Karl Popper's Conception of Human Nature
Karl Popper's advocacy of freedom and toleration, his belief in the power of ideas, and the possibility of democratic social reform, place him in the more optimistic strand of liberal thought. Yet his awareness of the human needs for regularity and tradition bolster a largely conservative and pessimistic conception of human nature. Epistemologies have a central role in Popper's political programme and theory of history because they influence either the release or suppression of key human capacities. Elucidating Popper's conception of human nature shows the origins of Popper's understanding of dogmatism and violence and indicates the underlying rationale for critical rationalism. But it also explains why Popper prefers revolutions in thought among élites to those in politics among the masses. To the extent that Popper's conception of human nature is problematic, so the political theory and epistemology may also be misconceived.
