Abstract

This chapter analyzes stupidity as a problem for epistemology. Its proper home belongs to virtue epistemology, as a specific epistemic vice, which has to be studied along the lines of both reliabilist virtue epistemology and of responsibilist virtue epistemology. The author distinguishes between two kinds of stupidity: stupidity proper and foolishness. The former is a defect in the competence of an agent, as well as in the performance of judgment, and it is generally studied as a failure of rationality along intellectualist lines. The second is a failure to evaluate properly the nature of the epistemic goal, and is a form of epistemic indifference, which involves an insensitivity to epistemic values and norms. This chapter analyzes their varieties, and suggest that the boundaries between stupidity and foolishness are often less clear than it is suggested by the author’s taxonomy.
