She Stoops to Conquer

One of the elements Goldsmith most skewers in his play's satirical moments is the aristocratic emphasis on behavior as a gauge of character. Even though we today believe that one's behavior – in terms of “low” versus “high” class behavior – does not necessarily indicate who someone is, many characters in the play are often blinded to a character's behavior because of an assumption. For instance, Marlow and Hastings treat Hardcastle cruelly because they think him the landlord of an inn, and are confused by his behavior, which seems forward. The same behavior would have seemed appropriately high-class if they hadn't been fooled by Tony. Throughout the play, characters (especially Marlow) assume they understand someone's behavior when what truly guides them is their assumption of the other character's class.

Much of this play's comedy comes from the trickery played by various characters. The most important deceits come from Tony, including his lie about Hardcastle's home and his scheme of driving his mother and Constance around in circles. However, deceit also touches to the center of the play's more major themes. In a sense, the only reason anyone learns anything about their deep assumptions about class and behavior is because they are duped into seeing characters in different ways. This truth is most clear with Marlow and his shifting perspective on Kate, but it also is true for the Hardcastles and Sir Charles, who are able to see the contradictions in others because of what trickery engenders.
