Why “agathist” is a great word
AGATHIST — [Noun] A person who believes all things ultimately tend toward the good, even if the path involves hardship or evil. From the Ancient Greek ἀγαθός (agathós, "good") + the English suffix -ist (denoting an adherent of a belief). First attested in English in 1816. Unlike an optimist, who expects favorable outcomes, or a pessimist, who expects the worst, an agathist adheres to a teleological faith in goodness as the final cause. It is the quiet conviction of the seed enduring the dark press of soil, of the weaver who incorporates a dark thread to give the tapestry depth, and of the one who finds in tragedy's catharsis the shape of a greater order—a belief not in the weather of the moment, but in the deep, directional currents of the sea.
