We get to hear a range of Wilde's voices. There is a conversation that feels like a cross between a Socratic dialogue and The Importance of Being Earnest. There is a much more traditional essay about the use of costume in Shakespearean theatre. Wilde expresses many fascinating ideas about art and criticism of art. And the Socratic piece in particular also makes is clear that he's not dogmatically claiming he's "right" about his arguments. A good essay isn't a final answer, its scaffolding for interesting conversation.
