The words themselves say least of all, if in fact they say anything; what really informs us is the inflection of the voice (and no less so if it is restrained), the breathing, the heartbeat, the muscles round the mouth and eyes, the dilation and conctraction of the pupils, the strength or the weakness in the knees, as well as the chain of mysterious reactions in the nerves and the secretions from hidden glands whose names one never knows even though one has read about them in books; all that is the essence of a conversation—the words are more or less incidental.
