Oscar Wilde, in The Importance of Being Earnest, uses wit as an ironic counterpoint to the absurdity of the play's action. This can be contrasted to the unconventional plot used by George Bernard Shaw in Saint Joan as a means of reinforcing his iconoclastic ideas.
Wilde uses cleverness and wit to give intelligence to his comedy. The action of Wilde's play has little if anything to do with reality or real human beings.

Wilde wants nothing more from the reader than for him or her to have a laugh or two at life and at themselves.
Shaw, on the other hand, has a much more serious idea in mind. He wants to show how Joan is a special sort o...
