The intuition deniers

‘Intuition deniers’ are those who—like Timothy Williamson, Max Deutsch, Herman Cappelen and a few others—reject the claim that philosophers centrally rely on intuitions as evidence. This ‘Centrality’ hypothesis, as Cappelen (2012, Philosophy without intuitions. Oxford University Press, Oxford) terms it, is standardly endorsed both by traditionalists and by experimental philosophers. Yet the intuition deniers claim that Centrality is false—and they generally also suggest that this undermines the significance of experimental philosophy. Three primary types of anti-Centrality argument have cross-cut the literature thus far. These arguments, I’ll claim, have differing potential consequences on metaphilosophical debate. The first sort of argument centers on worries about the term ‘intuition’—for instance, worries about whether it has clear application, or whether anything actually falls under it. Call this the Argument from Unclear Application. The second argument type involves the claim that evidence in philosophy consists not of facts (or propositions or what have you) about intuitions, but of facts about e.g. knowledge and causation. Call this the Argument from Antipsychologism. The third type involves an attempt to demonstrate that philosophers support their claims not via bald appeal to intuition, but via argumentation. Call this the Argument from Argumentation. Although these three arguments have merit, none of them undermines the importance of experimental philosophy. Nonetheless, they do have significant consequences for the methodological debates that dominate meta-philosophy, and for experimental philosophy in particular.
