Phrase - "A freedom that is never more authentic than when it is within the walls of a prison"

"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 voyeristic-sadistic idealization of the sexual relation; a personality that realizes itself on in suicide; a consciousness of the other than can be satisfied only by Hegelian murder" (page 6). 

This paragraph is Lacan's attempt to explain what has arisen in human beings due to the realization of our determination of our own lives, of existentialism. He explains that throughout history, the concept of the other has been passed down from generation to generation, and the idea of society has not grown past this kind of oxymoronic state. The duality emphasized here not only links back to Freud's concept of the double but to Plato's musings on the representations of reality which tend to distort it. Lacan goes on to say that our experiences are "prejudice" to the "dialectic of knowledge," and that we should not let our ego think that reality is too real.
