Ellison, as an artist in his fiction, not as a polemicist and propagandist, seeks the individual self and the dignity of human spirits challenging various powers which make human existence invisible. Ellison was one of the first black writers who made black culture "visible" by introducing much black folklore and tradition into their novels. Besides, the universality of Invisible Man is due to Ellison`s faithfulness to one of the black traditions-the Blues tradition. According to Ellison, the blues is an art from through which American Negroes have survived and kept their courage. He intended to give form and order to the racial conditions of America. Blues provides a model for structure as well as a method for conveying attitudes toward experiences. Like the blues, the novel ends as it begin; like the blues, each episode is a variation on one basic pattern. Negroes have conquered and transcended the agony of life by squeezing tragicomic lyricism from painful experiences through the blues. In singing the blues, they do not admit that they are losers, but claim their humanity and renew themselves by giving order and form to the dehumanizing circumstances. In Invisible Man, narrator discover that every institution is bent on processing and programming the individual in certain ways. Through assimilation and rebellion, he begin to realize his invisibility. In the end, he refuses to be manipulated by others and be mere role player. By confronting the world and life with tragicomic attitude, he transcended and transformed American Negroes` painful experiences into an art form in which everyone can find his own experience. Thus the blues can be considered as ritual to celebrate man`s ability to overcome chaos, so it is not so much personal song as song of communion which has public function. Blues was the aesthetic mainspring of Ellison`s writing.
