Jacques Lacan did not trust language. The French psychoanalyst’s suspicion of words was serious: In his late theories, he rejected them altogether as form of expression. “Where words fail, something else is appealed to” – he used mathemes instead:

Why was language so dubious and equivocal to Lacan? What made him understand it as “a gift as dangerous to humanity as the horse was to the Trojans”, as Zizek describes?
Some of Lacan’s assumptions:
No way out of the trap? Au contraire! As much as language is operating on us, a superior universe to which we are subdued, it is precisely and only through language that we can act back upon it.
A possible escape: The “language-destroying twisting of language” that poetry can be. Dada poets have proven it. The creation of a new (“non sense”) language was the moment of literary creation, in which – through the celebration of “the infinite plenitude of nonsensical” – existing rules of what art has to be, were challenged and the social order transformed.
