Centered on sex, the taboo topic for a long time, Sexual Personae by Camille Paglia tries to prove the continuality and integrity of western culture through emphasizing dualism of nature and civilization, male and female, earth worship and sky worship, heresy and Jew——Christianity, Dionysian and Apollonian spirits. Although the analysis is novel and special, the physiological characteristics of determinism of Naturalism makes Sexual Personae fall into reductionism. There is the risk of absolutism of theoretical frame by Camille Paglia for the dual separate of male and female, nature and arts in the name of sex. Sexual Personae is caught in relativity as well for the neglect of other scholars’ research and the random and incoherence of selecting text analysis subject.
