A mesure que le langage devient plus fonctionnel, il est rendu impropre a la parole, et 4 nous devenir trop particulier il perd sa fonction de langage.
Lacan articulates the constitutive antinomy of parole and langage: as language becomes purely functional it loses the power of speech, while overly private speech loses its linguistic function — the tension that defines the analytic field.
