A philosophical theory of criticism (usually of literature or film) that seeks to expose deep-seated contradictions in a work by delving below its surface meaning. This method questions the ability of language to represent a fixed reality, and proposes that a text has no stable meaning because words only refer to other words, that metaphysical or ethnocentric assumptions about the meaning of words must be questioned, and words may be redefined in new contexts and new, equally valid and even contradictory meanings may be found. Such new interpretations may be based on the philosophical, political, or social implications of the words of a text, rather than solely on attempts to determine the author's intentions.
