Abstract

This chapter analyzes the logical structure of Edmund Gettier‐style thought experiments. The discussion can be generalized to many imaginary counterexamples that have been deployed against philosophical analyses and theories in ways more or less similar to Gettier’s. The background working hypothesis is that his thought experiments are paradigmatic, in the sense that if any thought experiments can succeed in philosophy, his do: thus to determine whether Gettier’s thought experiments succeed is in effect to determine whether there can be successful thought experiments in philosophy. Gettier presents his specific counterexamples to the target analysis through short fictional narratives, in the present tense indicative, with fictional uses of proper names, all introduced by “suppose that.” One manifestation of the influence of past experience on epistemological judgments may be cross‐cultural variation in verdicts on thought experiments, including the Gettier case.
