Whether we interpret news reports or the Constitution of the United States, we read as much into texts as we extract from texts.
I chuckled when Jon Stewart deconstructed Betsy McCaughey and her “death panels” on “The Daily Show.” http://www.thedailyshow.com/watch/thu-august-20-2009/exclusive—betsy-mccaughey-extended-interview-pt–1
Still, was McCaughey doing anything worse than the rest of us do?
We all read INTO authoritative texts what we wish were there. That is eisegesis. Eisegesis is not confined to Glen Beck and Sarah Palin.
We all accept from time to time the discipline of deriving our interpretations FROM a document. That is exegesis.
Inside and outside readings and interpretations are almost always available to us. Little wonder, then, that we mix and match eisegesis with exegesis.
