Syn: Fanaticism.

Usage: 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]
