If Marcia is merely condemning “decency” for the sake of stirring up chaos, then Orcutt is doing the same thing when he argues in favor of decency—clearly, given his ongoing affair with Dawn, he isn’t genuinely concerned about decency and moral goodness. Critically, Marcia here references humankind’s expulsion from the idyllic Garden of Eden following Adam and Eve’s choice to disobey God and eat from the tree of knowledge, as conveyed in Genesis. As
American Pastoral’s subheadings (Part 1 is “Paradise Remembered,” Part 2 is “The Fall” and Part 3 is “Paradise Lost”) suggest, the Swede’s story is a contemporary reimagining of the Fall of Man, with Merry’s crime expelling the Swede from his own paradise as he is forced to confront the ugly, brutal reality of the world. The issues that Lou and Marcia fight over here reflect some of the broader concerns of the novel—whether it is foolish to live in denial about life’s ugly truths, whether the pursuit of knowledge and truth is always the most noble path one can take, and so on.
