thought which the study of evolution fosters, we are enabled distinctly to observe this tendency.  As this is the most wonderful of all the phases of that stupendous revolution in nature which was inaugurated in the Creation of Man, it deserves especial attention here; and we shall find it leading us quite directly to our conclusion.  From the Origin of Man, when thoroughly comprehended in its general outlines, we shall at length be able to catch some glimpses of his Destiny.

Universal Warfare of Primeval Men.

In speaking of the higher altruistic feelings as being antagonistic to the continuance of warfare, I did not mean to imply that warfare can ever be directly put down by our horror of cruelty or our moral disapproval of strife.  The actual process is much more indirect and complex than this.  In respect of belligerency the earliest men were doubtless no better than brutes.  They were simply the most crafty and formidable among brutes.  To get food was the prime necessity of life, and as long as food was obtainable only by hunting and fishing, or otherwise seizing upon edible objects already in existence, chronic and universal quarrel was inevitable.  The conditions of the struggle for existence were not yet visibly changed from what they had been from the outset in the animal world.  That struggle meant everlasting slaughter, and the fiercest races of fighters would be just the ones to survive and perpetuate their kind.  Those most successful primitive men, from whom civilized peoples are descended, must have excelled in treachery and cruelty, as in quickness of wit and strength of will.  That moral sense which makes it seem wicked to steal and murder was scarcely more developed in them than in tigers or wolves.  But to all this there was one exception.  The family supplied motives for peaceful cooeperation.[12] Within the family limits fidelity and forbearance had their uses, for events could not have been long in showing that the most coherent families would prevail over their less coherent rivals.  Observation of the most savage races agrees with the comparative study of the institutions of civilized peoples, in proving that the only bond of political union recognized among primitive men, or conceivable by them, was the physical fact of blood-relationship.  Illustrations of this are found in plenty far within the historic period.  The very township, which under one name or another has formed the unit of political society among all civilized peoples, was originally the stockaded dwelling-place of a clan which traced its blood to a common ancestor.  In such a condition of things the nearest approach ever made to peace was a state of armed truce; and while the simple rules of morality were recognized, they were only regarded as binding within the limits of the clan.  There was no recognition of the wickedness of robbery and murder in general.
