The critical opinions of a writer should always be taken with a large grain of salt. For the most part, they are manifestations of his debate with himself as to what he should do next and what he should avoid.
W. H. AudenDrama is based on the Mistake. I think someone is my friend when he really is my enemy, that I am free to marry a woman when in fact she is my mother, that this person is a chambermaid when it is a young nobleman in disguise, that this well-dressed young man is rich when he is really a penniless adventurer, or that if I do this such and such a result will follow when in fact it results in something very different. All good drama has two movements, first the making of the mistake, then the discovery that it was a mistake.
