"The mouth is beautiful. Everything starts with the mouth, from the first scream to the first sucking, from the first love kiss to the last farewell kiss. It is possible to view it only as an obscure hole or a devouring machine. It becomes more difficult when, from the labial to the short syllabe, it shapes itself as an instrument for language or music. Then, new questions are raised, especially regarding its relation to the cerebral systems." Claude Olievenstein
