The purpose of this article is to illuminate how James Fenimore Cooper reveals his prejudices on gender and race in The Last of the Mohicans. His prejudices on gender and race are embedded in patriarchal and racial discourses in which Cooper textualizes his views on the gender and racial ideologies of contemporary society and politics. Like other contemporary writers, who were concerned in Indian race, Cooper dramatized it in his fictions. In The Last of Mohicans, he deals with the subjects of women and Indian race with ambiguous and dual attitudes. Thus, many critics condemn his ambivalence and double attitudes revealed in his characterization in The Last of the Mohicans. In The Last of Mohicans, Cooper creates two main woman characters, Alice and Cora, as beautiful and charming, Alice is a white woman; on the other hand, Cora is a black-and-white woman. Both women are repressed in various ways because The Last of the Mohicans is the man-centered world in which society is governed by manly virtues and woman-centered social structure is rejected. His prejudices on women are revealed mainly in male characters` attitude such as Hawkeye, Duncan, and Magua. Women are maltreated and repressed by sexism and misogyny in the work. Especially Cora suffers from double discrimination, sexual and racial, because she is an offspring of a white man and a black woman. Cooper`s racial prejudice is also expressed in various ways in the novel. He dichotomizes Indians into two groups: bad and evil. He presents Uncas as a good Indian, but Magua as a bad Indian. As some critics points out, he has ambivalent attitudes toward Indian race. Hawkeye, outwardly, seems to be sympathetic about Indians, but, inwardly, he discloses a secret racial prejudice. He always emphasizes the purity of his white blood, devaluating and despising Indians` values. Besides Hawkeye, most characters, who have racial prejudices towards Indians, are sexists and racists. Cooper`s gender and racial prejudices are debunked even in the narrator`s patriarchal discourses. Upon close examination, Cooper can be seen to project his sexism and racism consciously and unconsciously through his characterization and patriarchal discourses.
