The sewer is the conscience of the city. Everything there converges and confronts everything else. In that livid spot there are shades, but there are no longer any secrets. Each thing bears its true form, or at least, its definitive form. The mass of filth has this in its favor, that it is not a liar. Ingenuousness has taken refuge there. The mask of Basil is to be found there, but one beholds its cardboard and its strings and the inside as well as the outside, and it is accentuated by honest mud. Scapin’s false nose is its next-door neighbor. All the uncleannesses of civilization, once past their use, fall into this trench of truth, where the immense social sliding ends. They are there engulfed, but they display themselves there. This mixture is a confession. There, no more false appearances, no plastering over is possible, filth removes its shirt, absolute denudation puts to the rout all illusions and mirages, there is nothing more except what really exists, presenting the sinister form of that which is coming to an end. There, the bottom of a bottle indicates drunkenness, a basket-handle tells a tale of domesticity; there the core of an apple which has entertained literary opinions becomes an apple-core once more; the effigy on the big sou becomes frankly covered with verdigris, Caiphas’ spittle meets Falstaff’s puking, the louis d’or which comes from the gaming-house jostles the nail whence hangs the rope’s end of the suicide. A livid foetus rolls along, enveloped in the spangles which danced at the Opera last Shrove-Tuesday, a cap which has pronounced judgment on men wallows beside a mass of rottenness which was formerly Margoton’s petticoat; it is more than fraternization, it is equivalent to addressing each other as “thou.” All which was formerly rouged, is washed free. The last veil is torn away. A sewer is a cynic. It tells everything.
