Antimetabolic

In rhetoric, a syntactic figure is referred to as an antimetabole (from Greek ἀντί antí , German 'against, different' , and μεταβολή metabol deutsch , German 'to implement, overturn' ) , where words are used in two sentences in opposite order. It is similar to chiasmus , which does not, however, take up the same terms or sentences, but contrasts similar patterns. Often the antimetabolic is accompanied by an antithesis :

• We don't live to work; we work to live.
• It is not people's consciousness that determines their being, but, conversely, their social being that determines their consciousness. ( Karl Marx )
