A well-dressed, intelligent, manipulative woman who is faintly connected to all three protagonists. She went to school with Lady Chiltern, was briefly engaged to Lord Goring, and has a fateful mutual friend with Sir Robert. Her dandyism superficially resembles Lord Goring’s in its preoccupation with fashion, wit, and pleasure, but there is a fundamental difference between them. Lord Goring seeks to separate conventional values from private values, their appearance from their reality, in order to honor that reality. Mrs. Cheveley seeks to conflate appearance with reality in order to discredit and trivialize moral reality, the empathetic moral core beneath the ornament of politeness. She implies that no such thing exists. This attitude, which initially seems like a sort of sophistication, is finally exposed as blindness.
