Antithesis
Antithesis
(Gr. anti-against, tithenai- to set) In a general sense, the opposition or contrast of ideas or statements.
In philosophy, a proposition opposed to a given thesis expressing a fact or a positive statement. With Kant, it is the negative member of the antinomies of reason. With Hegel, it is the second phase of the dialectical process, which denies the first moment or thesis, and which contributes to the emergence of the synthesis blending the partial truths of the thesis and the antithesis, and transcending them both.
In rhetoric, the contrast involved by an antithesis is technically expressed by the position of opposite words in one or more sentences or clauses. — T.G.
