Act III offers happy resolution to the problems of identity and marriage that drive much of the humor in the previous acts. Wilde continues to mock the social customs and attitudes of the aristocratic class. He relentlessly attacks their values, views on marriage and respectability, sexual attitudes, and concern for stability in the social structure.
Wilde attacks social behavior with the continuation of speeches by his characters that are the opposite of their actions. While Cecily and Gwendolen agree to keep a dignified silence, Gwendolen actually states that they will not be the first ones to speak to the men. In the very next line she says, "Mr. Worthing, I have something very particular to ask you." Wilde seems to be saying that people speak as if they have strong opinions, but their actions do not support their words. If actions truly do speak louder than words, Wilde has made his point: Society, literally, speaks volumes, but the words are meaningless.
Wilde continues his criticism of society's valuing style over substance when Gwendolen says, "In matters of grave importance, style, not sincerity is the vital thing." Lady Bracknell discusses Algernon's marriage assets in the same light. She says, "Algernon is an extremely, I may almost say an ostentatiously, eligible young man. He has nothing, but he looks everything. What more can one desire?" Indeed, in a society where looks are everything and substance is discounted, Algernon is the perfect husband.
