Abstract

The problem of the empirical basis is one of the most prominent difficulties within the Popperian tradition. Some claim that Popper’s anti-inductivism and antipsychologism lead to the concession that science has no empirical basis. Recent commentators have focused on this problem in Popper’s methodology. However, the problem also arises in a peculiar way in the thought of two underdiscussed members of the Popperian tradition: William Bartley and Paul Feyerabend. In this article, I aim to accomplish three primary goals. First, I argue that defenses of Popper’s solution to the problem of the empirical basis fail to address the deeper issues that have been pointed out by Popper’s critics. Second, I show how, despite Bartley’s efforts, he also succumbs to a modified version of the problem of the empirical basis. However, Bartley’s later work in evolutionary epistemology provides a more sensible response to the problem. Finally, I show how the problem arises in two distinct senses within Feyerabend’s methodology. I show how Feyerabend accidentally dissolves one sense of the problem and then provide a proposal for remedying the second version of the problem.
