A minimum of unconsciousness is necessary if one wants to stay inside history. To act is one thing; to know one is acting is another. When lucidity invests the action, insinuates itself into it, action is undone, and with it, prejudice, whose function consists, precisely, in subordinating, in enslaving consciousness to action. The man who unmasks his fictions renounces his own resources and, in a sense, himself. Consequently, he will accept other fictions which will deny him, since they will not have cropped up from his own depths. No man concerned with his equilibrium may exceed a certain degree of lucidity and analysis.
