"Sometimes when you have scrutinized a face long and persistently, you seem to discover a second face hidden behind the one you see. This is generally an unmistakable sign that this soul harbors an emigrant who has withdrawn from the world in order to watch over secret treasure, and the path for the investigator is indicated by the fact that one face lies beneath the other, as it were, from which he understands that he must attempt to penetrate within if he wishes to discover anything. The face, which ordinarily is the mirror of the soul, here takes on, though it be bur for an instant, an ambiguity that resists artistic production. An exceptional eye is needed to see it, and trained powers of observation to follow this infallible index of a secret grief. This eye is eager, and yet to solicitous; anxious and compelling, and yet so sympathetic; persistent and shrewd, and yet sincere and benevolent. It lulls the individual into a certain pleasant languor, in which he finds an almost voluptuous pleasure in pouring forth his grief, like the pleasure said to accompany blood-letting. The present is forgotten, the external is broken through, the past is resurrected, grief breathes easily. The sorrowing soul finds relief, and sorrow’s sympathetic knight errant rejoices that he has found the object of his search; for we seek not the present, but sorrow whose nature is to pass by. In the present it manifests itself only for a fleeting instant, like the glimpse one may have of a man turning a corner and vanishing from sight."
