Hello Following JeanDeSponde's lacanic post I have checked up to try and see what Lacan was referring to. The word appears in his seminar of 17.3.71 (Le sĂ©minaire, Vol XVIII) on "Lituraterre" and it only seems to refer to those (westerners) ignorant of Chinese calligraphy."Produire la rature dĂ©finitive, c'est cela l'exploit de la calligraphie. . "Les non-dupes errent: The unduped wander/are mistaken. That has a funny sound, huh? It is my kind of little air. Or to put things better, a little 'erre', and it sounds the same as 'les noms du pĂȘre' (the names of the father)."
