The Archaeology of Knowledge and the Discourse on Language
150- "Contradiction is the illusion of a unity that hides itself or is hidden: it has its place only in the gap between consciousness and unconsciousness, though and the text, the ideality and the contingent body of expression. In any case, analysis must suppress contradiction as best it can. At the end of this work, only residual contradictions remains- accidents, defects, mistakes."
151- "contradiction, then, functions throughout discourse, as the principle of its historicity."
-"Discourse is the path from one contradiction to another."
