Remarks on Ángel Pinillos’ Treatment of Global Skepticism in Why We Doubt

Ángel Pinillos’ Why We Doubt offers an error theory for at least some versions of global skepticism: skeptical doubts are based on a faulty heuristic. Once this heuristic is replaced by a more apt principle inspired by Bayesian approaches to epistemology, the skeptical doubts are shown not to be motivated. I argue contra Pinillos that skeptical doubts may remain even if we grant the main line of Pinillos’ argument. Skeptical doubts might be generated by disagreement even when we accept Pinillos’ Bayesian inspired principle.
