Lacan

“At the culmination of the historical effort of a society to refuse to recognize that it has any function other than the utilitarian one, and in the anxiety of the individual confronting the ‘concentrational’ form of the social bond that seems to arise to crown this effort, existentialism must be judged by the explanations it gives of the subjective impasses that have indeed resulted from it; a freedom that is never more authentic than when it is within the walls of a prison, a demand for commitment, expressing the impotence of a pure consciousness to master any situation; a voyeuristic-sadistic idealization of the sexual relation; a personality that realizes itself only in suicide; a consciousness of the other that can be satisfied only by Hegelian murder.”
