What actually took place was this. The division of the race into separate stems, and the corruption of the conception of God into separate divinities, pursued a parallel course, until the deities became as national as the communities over which they presided. As there ceased to be in their thought one God of the whole earth, they ceased to believe in one race of man, nor does any good seem to have more utterly perished from the peoples who sprung out of this dispersion than the belief in the universal brotherhood of man; and the conduct which should spring out of that belief, the treatment of each other as brethren. That their having lost the consciousness of such brotherhood is no proof that it never existed, has been established for us by the new science of comparative grammar in our own day in a very remarkable instance. The careful study of a single family of languages in the great race of Japhet has proved beyond question that those who came after their dispersion to speak the Sanscrit, the Persian, the Greek, the Latin, the Celtic, Slavic, and Teutonic tongues, all once dwelt as brethren beside a common hearth, in the possession of the same language. Yet, in ancient times, it never crossed the mind of the Greek that he was of the same family with the Persian, by whose multitudinous inroad he was threatened; to him the barbarian, that is the man who did not speak his tongue, was his enemy, not a brother. As little did the Saxon, when he displaced the Celt, and gave him, too, the name of barbarian,[10] as not understanding his tongue, conceive that he was of the same family. It was with no little wonder that the first French and English students of Sanscrit found in it uneffaced the proofs of its parentage with Greek and Latin. The study of the comparative grammar of various languages, when carried out as fully in other directions, may have in reserve other surprises as great as this; but the proof of unity in this case, where yet the divergence has proceeded so far, of unity in a family from which the greatest nations of the earth have sprung, and whose descendants stretch over the world, tends to make the unity of the original language of man credible on principles of science, independently either of historical tradition or of revelation, while it shows into what complete and universal oblivion a real relationship may fall.
