In Native Son, Wright employs Naturalistic ideology and imagery, creating the character of Bigger Thomas, who seems to be composed of a mass of disruptive emotions rather than a rational mind joined by a soul. This concept introduces the possibility that racism is not the only message of the novel, that perhaps every person would feel as isolated and alone as Bigger does were he trapped in such a vicious cycle of violence and oppression. Bigger strives to find a place for himself, but the blindness he encounters in those around him and the bleak harshness of the Naturalistic society that Wright presents the reader with close him out as effectively as if they had shut a door in his face.
