upon their elder sisters, and have in their turn absorbed or spiritualized them." But there would still be room to ask whether all this development had been natural and spontaneous, whether successive imitations linking one contiguous people to another had not transformed some local and isolated phenomenon into an apparently general and international fact--much as took place with the use of tea or cotton--without our being compelled to recognize any necessary law of human development in it. But what answer is possible to the argument furnished by the discovery of the new planet--I mean to say of America? How can we resist this evidence that the whole organism of mythologies, gods, goddesses, sacrifices, temples and priesthoods, while varying enormously from race to race and from nation to nation, yet, wherever human beings are found, develops itself under the same laws, the same principles and the same methods of deduction; that, in a word, given human nature anywhere, its religious development is reared on the same identical bases and passes through the same phases? Mr. Max Müller, one of my most honoured masters, and one of those who have best deserved the gratitude of the learned world, has declared, with equal justice and penetration, in his Preface to Mr. Wyatt Gill's "Myths and Songs," that the possibility of studying the Polynesian mythology is to the historian what an opportunity of spending a time in the midst of the plesiosauri and the megatherions would be to the zoologist, or of walking in the shade of the vast arborescent ferns that lie buried under our present soil to the botanist. Polynesian mythology has in fact preserved, down to our own day, the pre-historic ages. And, similarly, the religions of Mexico and Peru (for the empire of the Incas held the same surprises and the same lessons in store for its explorers as that of Montezuma had done) has enabled history to carry to the point of demonstration its fundamental thesis of the natural development, in subjection to fixed laws, of the religious tendency in man. All those curious resemblances, amidst the differences which we shall also bring out, between the religious history of the New World and that of the Old, are not at bottom any more extraordinary than the fact that, in spite of the differences of physical type which separated the natives from their conquerors, they none the less saw with eyes, walked on feet, ate with a mouth and digested with a stomach. * * * * *
