Exoter

Exoter is a rarely used English noun referring to a person who adheres to exoteric doctrine or to the outer, publicly accessible teachings of a philosophy, religion, or organization. In this sense, an exoter is contrasted with an esoter, someone associated with inner, hidden, or secret teachings.

Etymology and scope: The term derives from exoteric, which comes from Greek exōterikos (external, outward). As a noun, exoter is primarily found in historical or occult contexts, where it denotes a person aligned with outward-facing or public doctrine rather than with inner mysteries.

Usage and context: In occult, esoteric, and comparative religious literature, exoter is used to describe members of an outer circle who engage with publicly taught principles, rituals, or ethics. The distinction often appears alongside terms like esoteric and esotericism, which refer to inner knowledge, hidden rites, or advanced initiatory teachings. The exact meaning can vary by tradition, with some groups emphasizing a clear outer/inner division and others using more fluid categorizations.

Modern usage: The noun exoter is uncommon in contemporary scholarship and writing. More often, authors refer to exoteric teachings or describe individuals as adherents of an exoteric tradition, using the related adjective exoteric rather than the standalone noun.
