Approached The Edge

Discourse theory is an important part of Foucault's academic thought, which is constructed on the basis of his criticizing structuralism linguistics and literature theory. "Discourse" is defined as a kind of practical activity by Foucault, and in the course of its production and circulation, outside repelling principle, inside purifying principle, subject controlling principle play an important role all the time, from which the fact that power is the most ultimate factor of controlling discourse can be concluded. In other words, grasping power means grasping discourse. Moreover, the literature text obtains its meaning in discourse, and discourse is a whole set of inherent unifying which has relevance to specific themes and subjects and provides assumption, rule and expectation for specific text's thinking and expression. So the paper studies the discourse relations in literature text and discourse background that the text is produced by means of analyzing case in order to find self-identities crisis of different subjects who participate in discourse formation, thus seek and grasp the correlations between subjects controlling discourse power and those losing discourse power or submitting to discourse power. At the same time, we can find the existence state of "the other" who lies on the fringe and then go in quest of the way to go out of the fringe.The main body is divided into four parts: Part one focuses on Foucault's discourse theory and explores the power mechanism in discourse controlling principles. Part two analyzes the complicated relations between individuals controlling discourse power and those losing discourse power in literature texts. Part three traces back to the discourse tradition that the specific text is produced and explores the existence state of "the other". Part four tries hard to probe the way to go out of the fringe in order to arouse human beings concerning individuals' existing situation.
