What metaphors are used in Shakespeare: The Invention of the Human by Harold Bloom?

In the section titled, Measure for Measure, we learn that the play begins with the Duke on holiday, and his deputy Angelo taking over Vienna. Soon, Angelo has Claudio charged with unlawful fornication with Juliet and he is sentenced to death. The critic Marc Shell argues that by Shakespeare making fun of Angelo's strict enforcement of the law on fornication, this is a metaphor for Shakespeare's using the play to attack the notion of law and order altogether.
