It is obvious that in making this experiment M. Clemenceau exercised a great deal of care and forethought. The articles reprinted are not presented haphazard, nor without an evident intention of producing the best effect possible. They are selected on a peculiar system from the mass of the journalist's miscellaneous output. The collection has a central idea, and this is developed in a very remarkable preface, which remains one of the author's most philosophical and most elaborate compositions. This central idea is the tragical one of the great vital conflict which pervades the world, has always pervaded it, and must ever remain unaffected by the superficial improvements of civilization. All through the universe the various living organisms are in a condition of ceaseless contest. Everywhere something conquers something else which is conquered, and life sustains itself and ensures its own permanence by spreading death around it. Life, in fact, depends on death for its sustaining energy, and the fiercer the passion of vitality the more vehemently flourishes the instinct of destruction. The imagination of the author of _La Mêlée Sociale_ broods upon the monstrous facts of natural history. If he traverses a woodland, he is conscious of a silent army of beasts and birds and insects, and even of trees and plants, which are waging ceaseless battle against others of their kind. If he begins to stir the soil of a meadow with his foot, he refrains with a shudder, since millions of corpses lie but just below the surface of the fruitful earth. He peers down into the depths of the sea, only to recognize that a prodigious and unflagging massacre of living forms is necessary to keep the ocean habitable for those who survive. Everywhere, throughout the universe, he finds carnage triumphant; and eternal warfare is the symbol of the instinct of self-preservation.
