 When Lacan mentions “structure,” a word to which he has frequent recourse, he usually is thinking of his register of the Symbolic. Between the periods of his “return to Freud” and later teachings, Lacan reconsiders and alters what is conceptualized under the heading of the “like a language” (comme un langage) part of his fundamental claim that, “the unconscious is structured like a language.” However, from the 1950s until his death, his specific rendition of Freud’s discovery consistently holds to the thesis that, “the unconscious is structured.” That is to say, the unconscious, as bound up with that which is Symbolic, is an intricate, labyrinthine web of ideational representations interconnected in multiple sophisticated manners. Contrary to the crudeness of commonplace vulgar picturings of Freudian analysis as an irrationalist, neo-romantic psychology of the unruly natural depths, the unconscious is not the id, namely, an anarchic seething cauldron of unthinking animalistic instincts (i.e., something unstructured).
