Serres’ critic of Descartes is that he “desires to build a closed system, to think or to build without error or interruption,” but this is impossible because to be in the world is “to be dependent, to be an intermediary, a go-between, to be one thing among many, inhabiting a system in cascade” (49-50). How does this relate to Yates’ description of the prison escape of 1597? How is the escape and Peyton’s investigation of it “a system in cascade”?
