of cool neglect, he persisted in filling their cup to overflowing. Not only does he criticise civilization, the society of production for profit, the fundamental form of human society, in a manner savoring of Fourier, but he also speaks of a future reorganization of society in language that Karl Marx might have used. Consequently, he receives his just deserts, when McLennan indignantly charges him with a profound antipathy against historical methods, and when Professor Giraud-Teulon of Geneva endorses the same view in 1884. For was not the same Professor Giraud-Teulon still wandering about aimlessly in the maze of McLennan's exogamy in 1874 (Origines de la famille)? And was it not Morgan who finally had to set him free?
It is not necessary to dwell in this preface on the other forms of progress which primeval history owes to Morgan. Reference to them will be found in the course of my work. During the fourteen years that have elapsed since the publication of his main work, the material contributing to the history of primeval society has been considerably enriched. Anthropologists, travelers and professional historians were joined by comparative jurists who added new matter and opened up new points of view. Here and there, some special hypothesis of Morgan has been shaken or even become obsolete. But in no instance has the new material led to a weakening of his leading propositions. The order he established in primeval history still holds good in its main outlines to this day. We may even say that this order receives recognition in the exact degree, in which the authorship of this great progress is concealed.
