"Nothing," says Max Müller, "necessitates the admission of different independent beginnings for the _material_ elements" [the vocabulary] "of the Turanian, Semitic, and Aryan branches of speech." The same thing Müller affirms of "the formal elements" [the grammatical structure] "of these groups of languages." "We can perfectly understand how, either through individual influences or by the wear and tear of speech in its continuous working, the different systems of grammar of Asia and Europe may have been produced." (_Lectures on Language_, 1st series, p. 340.) The same conclusions are reached by Professor W. D. Whitney, who, while disclaiming for linguistic science the power to prove that the human race in the beginning formed one society, says, that it is "even far more demonstrable" that it can "never prove the variety of human races and origins." (_Life and Growth of Language_, p. 269.) We know that nations can learn and unlearn a language. The Irish, adopting the language of their English conquerors, is one of many examples of the same sort in history. What effects upon language took place, prior to recorded history, from the mingling of tribes and peoples, it is impossible to ascertain. The consequences to language, of mixture among different forms of speech, were like those which must have been produced upon the physical man from the mingling of diverse physical types in remote ages. Science, if it has no decided verdict to render, does not stand in conflict with the monogenist doctrine, which has generally been understood to be the teaching of the Scriptures. MYTHOLOGY. The polytheistic religions are in themselves a highly interesting part of the history of mankind. In the multiform character that belongs to them we find reflected the peculiar traits of the several peoples among whom they have arisen. The history of religion stands in a close connection with the development of the fine arts,--architecture and sculpture, painting, music, and also poetry. The earliest rhythmical utterance was in hymns to the gods. To worship, all the arts are largely indebted for their birth and growth. This, however, is only one of the ways in which religion is interwoven with the rise and progress of civilization.
