Abstract

Fanaticism involves a robust and epistemically peculiar form of commitment: the fanatic is willing to sacrifice himself and others for the sake of his goal, and the fanatic is unable or unwilling to adjust his commitment in light of critical reflection. But is this always morally bad? While Cassam (Extremism: a philosophical analysis, Routledge, New York, 2022b) and Katsafanas (Philos Imprint 19:1–20, 2019; Philosophy of devotion: the longing for invulnerable ideals, Oxford University Press, Oxford, 2023a) have offered accounts of fanaticism that treat it as vicious, Battaly (Synthese 201:1–27, 2023) and others have argued that fanaticism is morally neutral: whether it is bad or good depends on several factors, including the context in which it occurs and the ends toward which it is directed. I argue that these debates are marred by a failure to distinguish devotion and fanaticism. Devotion captures what is good in fanaticism; fanaticism is a morally vicious form of devotion. Fanaticism is a form of devotion that springs from a morally problematic psychological profile.
