△Mac. 2. 3. 9 (8):“Faith,here’s an equivocator,that could swear in both the scales against eitherscale,who committed treason enough for God’s sake,vet could not equivocate to heaven. ” (An allusion toGarner,a Jesuit who confessed to the use of equivoca-tion at a trial of the Gunpowder plot in 1606)哼，这一定是一个说话模棱两可的家伙，能在正义的两个秤盘上两边发誓、两边骂，他打着上帝的名义犯下不少的叛逆之罪，但还是没法混进天堂。
