Erica Jong`s Fear of Flying has garnered widespread compliment and criticism at the same time since its publication in 1973 due to its explicit depiction of female sexuality. In this paper, I maintain that while Jong as a feminist courageously challenges a commonly held sexual script with her female protagonist, Isadora Wing, who is sexually licentious indeed, her identity is nonetheless torn between a sexually liberated feminist and a lover whose passionate pursuit for committed love could be misconstrued as backlash against feminism. In the novel, Jong attempts to create a new way of ``becoming a woman`` in a Deleuzian sense: in this case, a woman who loves a man with passion and preserves her own identity, which has been difficult to attain in this patriarchal world where love costs identity for women. I claim that Jong`s adoption of comic elements including irony and self-caricature as narrative strategies makes a smart contribution to paving her own unique way against feminist and anti-feminist hostility, and her seemingly irrelevant exploration into Jewish identity rather effectively strengthens the novel`s theme of ``becoming a woman.``
