M. Keith Booker cites the episode in his 2006 book "Drawn to Television", while discussing "The Simpsons" treatment of religion. Booker cites a scene from the episode where Milhouse asks Bart what religions have to gain by lying about concepts such as the existence of a soul – and then the scene cuts to Reverend Lovejoy counting his money; Booker believes that this implies that religions create mythologies so that they can gain money from followers. He juxtaposes this with Bart's realization later in the episode that "life suddenly feels empty and incomplete" without a soul, which suggests "either that the soul is real or it is at least a useful fiction". Mark I. Pinsky and Samuel F. Parvin discuss the episode in their book "The Gospel According to the Simpsons: Leader's Guide for Group Study", and use examples from it to stimulate discussion among youth about the nature of the soul. Pinsky and Parvin note Bart's statement to Milhouse from the beginning of the episode: "Soul — come on, Milhouse, there's no such thing as a soul. It's just something they made up to scare kids, like the Boogie Man or Michael Jackson", and then suggest questions to ask students, including whether they know individuals that agree with Bart, and their views on the existence of a soul.
