white man ruled society, but he never achieved his goal. This revealed the contradiction of capitalism.
With the development of the capitalism, the black man also could not find their position. They had no freedom and no right to choose their life, because the society was ruled by the white people. Invisible Man was written in this situation, the hero's invisibility owned to the fast development of capitalism.

Conclusion
Ralph•Ellison is an American black writer. He has made a success in American literature. He uses his novel Invisible Manto awake all blacks rather than to depress them. Ellison's idea of tracking down black's self-identity is embodied sufficiently in the book Invisible Man. In American society, blacks are driven into a corner because of racial discrimination and oppression and the unequal treatment. Ellison's book Invisible Man is a story about a black man who is invisible to the American society. The hero tries his best to be excellent not only among the white people but also among the black people. But no matter how well he performed, he never achieves the thing he wants to get. He is an invisible man without no name and no identity. Is this hero really invisible? Certainly not. He is invisible because of the existing of racial discrimination. Under this situation, the black have no real freedom and have no dignity and no right to living in this society. They have struggled a lot in political, economic and cultural field, but achieve nothing. Another reason of the hero's invisibility is his being lost of himself. As a Negro, he can not find the right position of living in this society. His innocence and his rejection to his national culture also let him lost. The third reason of the hero's invisibility comes from the fast economic development of the capitalism. It makes the black people become associated to machine and makes them lose humanility. This are the root causes of the hero's being invisibility.
Ellison's novel Invisible Man is regarded as one of masterpieces of American literature, and its influence on American society is going on in modern time. All in all this thesis is just an initial exploration into the root causes of the invisibility of the hero in Invisible Man. Because of the limitation of the author's knowledge, the present study is by no means comprehensive or complete, so some future researchers are still needed to study it profoundly.
