No! “It is never safe,” said Luther, “to do anything against the truth!” Truth alone is safe; and his soul only is safe who loves and honors truth more than human approbation—more than ease, comfort, or life. It is not safe to pretend to believe what we do not. And in this instance, half of the infidelity of the age and country has come from the teaching that everything in the Bible is the word of God. Sincere men have been disgusted when told they must believe things contrary to their common sense and reason. Another question, which is now being investigated, is the age of mankind—the antiquity of the human race. The Bible gives the list of generations from Adam to Abraham; and the length of each, and other data, given in Scripture, make six thousand years for the life of man on this earth. Greek history only goes back some twenty-three hundred years; the Egyptian monuments go back fifteen hundred or two thousand years earlier—to 2000 B.C., or 3000 B.C. The “Vedas,” in India, may have been written 1500 B.C.; the “Kings,” in China, before that. But recently we have been carried back to a yet earlier period,—to a time when man existed on the earth, before any written monument or sculptured stone which now exists. _Two_ different sources have been discovered within a few years,—one of them by philology, the other by geology. It has been found that the languages spoken by Europeans, in their airy sounds, are more permanent monuments than granite or enduring brass. Stamped on these light, imponderable words are marks of a gray antiquity going back to times before Herodotus, before Moses and the book of Genesis, before the Vedas in India, before the Zendavesta in Persia. It has been proved, first, that nearly all the languages of Europe belong to one linguistic family, and therefore that those who speak them were originally of one race. These different languages—seven sister languages, daughters of a language now wholly gone—are the Sanscrit or ancient Hindoo, the Zend or ancient Persian, the Greek, the Latin, the Keltic, the German, and the Slavic languages. By a comparison of these, it has been found that originally there lived, east of the Caspian, a race of shepherds and hunters, calling themselves _Aryan_; that one branch descended into India at least five thousand years ago, and drove out the aboriginal inhabitants, a second branch went into Persia, a third into Italy, a fourth into Greece, a fifth vast immigration filled Northern Europe with the Kelts, a sixth with Scandinavians and Germans, and a seventh with the Slaves. But long ago as this immigration was,—before all history,—it found aboriginal inhabitants everywhere, whose descendants remain. The Lapps and Finns in Northern, Europe, the Basques in Spain, and Magyars in Hungary, are probably descended from this earlier European race. It is difficult to suppose mankind only six thousand years old, when we find such great movements taking place four or five thousand years ago.
