ATARAXY

ATARAXY, Ataraxia, a term much used by the Stoics, to denote that calmness and tranquillity of mind, and that firmness of judgment which sets us free from any agitations or emotions arising from self-opinion, and the knowledge we imagine ourselves possessed of. See STOICS. In this Ataraxia, they supposed the sovereign good to consist.
See GOOD. The word is purely Greek, compounded of ἀ-, a privative prefix, and τάραξις, disorder; hence, Ataraxia implies a state of being untroubled.
