Hi Carly,

I think another way that Giovanni attempts to justify his love/desire for his sister is through appropriating  the lexias of different forms of discourse. For example, in the opening lines, he uses both medical and religious language to justify his relationship. More broadly, I think that Ford could be making a broader point about the limits of logic and reason and is asking us to look closer when a form of reason seems complete and unwavering–such as the Friar’s interpretation of religion.
