Is it certain that there corresponds to the word communication a unique, univocalconcept, a concept that can be rigorously grasped and transmitted: a communicable concept? Following a strange figure of discourse, one first must ask whether the word or signifier "communication" communicates a determined content, an identifiable meaning, a describable value. But in order to articulate and to propose this question, I already had to anticipate the meaning of the word communication: I have had to predetermine communication as the vehicle, transport, or site of passage of a meaning, and of a meaning that is one. If communication had several meanings, and if this plurality could not be reduced, then from the outset it would not be justified to define communication itself as the transmission of a meaning, assuming that we are capable of understanding one another as concerns each of these words (transmission, meaning, etc.).
