Antithesis
Antithesis is a figure of speech involving a seeming contradiction of ideas, words, clauses, or sentences within a balanced grammatical structure. Parallelism of expression serves to emphasize opposition of ideas. The familiar phrase ÃÂÃÂMan proposes, God disposesÃÂÃÂ is an example of antithesis, as is John Dryden's description in ÃÂÃÂThe Hind and the PantherÃÂÃÂ: ÃÂÃÂToo black for heaven, and yet too white for hell.ÃÂÃÂIn grammatical usage antithesis is often expressed by means of an antonym, such as high - low, to shout - to whisper, lightness - heaviness, etc.
