Syn. -- Fanaticism. -- Superstition, Fanaticism. Superstition springs from religious feeling misdirected or unenlightened. Fanaticism arises from this same feeling in a state of high-wrought and self-confident excitement. The former leads in some cases to excessive rigor in religious opinions or practice; in others, to unfounded belief in extraordinary events or in charms, omens, and prognostics, hence producing weak fears, or excessive scrupulosity as to outward observances. The latter gives rise to an utter disregard of reason under the false assumption of enjoying a guidance directly inspired. Fanaticism has a secondary sense as applied to politics, etc., which corresponds to the primary. [ 1913 Webster ]
