In "The Great Gatsby," Daisy, when asked about her daughter, states that she is happy her child is a girl and that she wishes for her to be a beautiful fool. The novel is by F. Scott Fitzgerald.
The statement about Daisy Buchanan's daughter, Pammy, comes in a conversation between Daisy and Nick Carroway, who is a close friend and cousin. She is telling Nick about her daughter's birth and is expressing bitterness over her husband's apparent extramarital affair with a woman named Myrtle. Daisy believes that a fool is all that a girl can aspire to be in the world.
