ギリシャ語のhypokrisis, stage performance, playから、hypo-, under, -kris, to separate, sift, commentから、語源はcrisis, criterionと同じ。古代ギリシャの舞台パフォーマンスの一形態、すなわち、スピーチの後に意見、コメント、推敲を加えることから、派生してperformance, playとなった。現在の偽善、hypocrisyの語源はこれか、またはhypo-, below, lacking, -kris, comment, opinion, すなわち、意見や見解をあえて述べない、本音を隠す、偽善、hypocrisyの派生語であろう。
Hypocrisy is the art of affecting qualities for the purpose of pretending to an undeserved virtue. Because individuals and institutions and societies most often live down to the suspicions about them, hypocrisy and its accompanying equivocations underpin the conduct of life. Imagine how frightful truth unvarnished would be. [Benjamin F. Martin, "France in 1938," 2005]
