"No authority could have been strong enough to persuade the Grecian army [of Alexander] that their gods and their hero-ancestors were the same as those of [the Indian] King Porus, or to convince the English soldier that the same blood was running in his veins, as in the veins of the dark Bengalese. And yet there is not an English jury now-a-days, which, after examining the hoary documents of language, would reject the claim of a common descent and a legitimate relationship between Hindu, Greek, and Teuton. Many words still live in India and in England that witnessed the first separation of the northern and southern Arians, and these are witnesses not to be shaken by any cross-examination. The terms for God, for house, for father, mother, son, daughter, for dog and cow, for heart and tears, for axe and tree, identical in all the Indo-European idioms, are like the watch- words of an army. We challenge the seeming stranger, and whether he answer with the lips of a Greek, a German, or an Indian, we recognize him as one of ourselves. Though the historian may shake his head, though the physiologist may doubt, and the poet scorn the idea, all must yield before the facts furnished by language. There was a time when the ancestors of the Celts, the Germans, the Slaves [sic], the Greeks and Italians, the Persians and Hindus, were living together beneath the same roof, separate from the ancestors of the Semitic and Turanian races."
