antithesis

noun

Etymology: Borrowed from Latin antithesis, itself a borrowing from Ancient Greek ἀντίθεσις (antíthesis). By surface analysis, anti- + thesis.

1. A proposition that is the diametric opposite of some other proposition.

   “For if every condition of everything conditioned (according to its existence) is sensuous, and therefore belongs to the series, that series is again conditioned (as shown in the antithesis of the fourth antinomy).”

   “Unless one final Schlafly paradox gets in the way. Before she died, the First Lady of the Conservative Movement endorsed Trump. That makes sense: Schlafly was a paleoconservative who was worried about immigration. But Trump has turned out to be the most unchivalrous candidate in living memory, the very antithesis of Schlafly’s ideal Christian standard.”

2. A device by which two contrasting ideas are juxtaposed in parallel form; a figure of speech arranged in this manner

   “Antithesis, opposing things to things, Oft from the contrast strength and beauty brings.”

3. The second stage of a dialectical process in which the thesis is negated.
