Discourse, Power and Subject ——On Post-Structurist Foucault's Theory Analysis

According to Foucault's discourse theory, the most distinct and indiscernible place that embodies the manifolds operational forms of power is the discourse which composes of the foundational part of generic cultural practice. Discourse radiates the influence of power, and it's a substitutive thing of power in whole modernistic society system. The power relation executes the power rule when it produces the discourse of truth. The use of discourse theory turns literary critics away from search of meaning, and it turns us from question of method to description of function, especially turns us to the question of how the subject is produced in social discourses and institutions and how the subject becomes the question of subject-function.
