[B]y reinterpreting Freudianism in terms of language,....

“ [B]y reinterpreting Freudianism in terms of language, a pre-eminently social activity, Lacan permits us to explore the relations between the unconscious and human society. One way of describing his work is to say that he makes us recognize that the unconscious is not some kind of seething, tumultuous, private region ‘inside’ us, but an effect of our relations with one another. The unconscious is, so to speak, ‘outside’ rather than ‘within’ us — or rather it exists ‘between’ us, as our relationships do. ”
