Of everything,--including the upper levels, which it execrates. It not only undermines in its hideous labor the existing social order, but it undermines philosophy, science, the law, human thought, civilization, revolution, and progress, and it calls itself most simply, robbery, prostitution, murder, and assassination. It is darkness, and desires chaos, and its roof is composed of ignorance. All the other mines above it have only one object, to suppress it; and philosophy and progress strive for this with all their organs simultaneously, by the amelioration of the real, as well as the contemplation of the ideal. Destroy the cave, Ignorance, and you destroy the mole, Crime. Let us condense in a few words a portion of what we have just written. The sole social evil is darkness; humanity is identity, for all men are of the same clay, and in this nether world, at least, there is no difference in predestination; we are the same shadow before, the same flesh during, and the same ashes afterwards: but ignorance, mixed with the human paste, blackens it, and this incurable blackness enters man and becomes Evil there. CHAPTER III. BABET, GUEULEMER, CLAQUESOUS, AND MONTPARNASSE. A quartette of bandits, Babet, Gueulemer, Claquesous, and Montparnasse, governed, from 1830 to 1835, the lowest depths of Paris. Gueulemer was a Hercules out of place, and his den was the Arche-Marion sewer. He was six feet high, had lungs of marble, muscles of bronze, the respiration of a cavern, the bust of a colossus, and a bird's skull. You fancied you saw the Farnèse Hercules, attired in ticking trousers and a cotton-velvet jacket. Gueulemer built in this mould might have subdued monsters, but he had found it shorter to be one. A low forehead, wide temples, under forty years of age, but with crow's-feet, rough short hair, and a bushy beard,--you can see the man. His muscles demanded work, and his stupidity would not accept it: he was a great slothful strength, and an assassin through nonchalance. People believed him to be a Creole, and he had probably laid his hands upon Marshal Brune when massacred, as he was a porter at Avignon in 1815. From that stage he had become a bandit.
