ABSTRACT
William Bartley’s pancritical rationalism is the subject of inquiry in this chapter, which reviews Bartley’s non-justificational epistemology and its origin in Popper’s philosophy of science. Then, Bartley’s problem with Popper’s critical rationalism is explained. Against this background, Chapter 3 focuses on Bartley’s pancritical rationalism as a theory of rationality, not merely a moral attitude of openness to criticism. The chapter reaches the conclusion that pancritical rationalism cannot tell us how the rationalist uses logic to refute his claim of rationality. It argues that the philosophy of critical rationalism is to be reinvented to address the question of how reason works to drive human action.
