Second class on Plato: the Cave, Socrates’s argument with poetry early and late

Second class on Plato: the through line in Socrates being his ambivalence about poetry: in the Republic, in the Ion, for example.  His penchant for quoting Homer despite this.  Compared to Hamlet quoting Aeneas's Tale to Dido.  What threat does poetry represent to philosophy? Both seek the same ground as discourses of everything.  The idea of divine inspiration: the magnetic influence of poetry.  More on forms.  The form of mud in the Parmenides.
