Moreover, the authority of each of these supreme gods is not limited to a single tribe; it is recognized equally by a number of neighbouring tribes. Bunjil is adored in nearly all of Victoria, Baiame in a considerable portion of New South Wales, etc.; this is why there are so few gods for a relatively extended geographical area. So the cults of which they are the object have an international character. It even happens sometimes that mythologies intermingle, combine and make mutual borrowings. Thus the majority of the tribes who believe in Baiame also admit the existence of Daramulun; however, they accord him a slighter dignity. They make him a son or brother of Baiame, and subordinate to this latter.[962] Thus the faith in Daramulun has spread in diverse forms, into all of New South Wales. So it is far from true that religious internationalism is a peculiarity of the most recent and advanced religions. From the dawn of history, religious beliefs have manifested a tendency to overflow out of one strictly limited political society; it is as though they had a natural aptitude for crossing frontiers, and for diffusing and internationalizing themselves. Of course there have been peoples and times when this spontaneous aptitude has been held in check by opposed social necessities; but that does not keep it from being real and, as we see, very primitive. To Tylor this conception has appeared to be a part of so elevated a theology that he refuses to see in it anything but the product of a European importation: he would have it be a more or less denatured Christian idea.[963] Andrew Lang, on the contrary, considers them autochthonous;[964] but as he also admits that it is contrasted with all the other Australian beliefs and rests on completely different principles, he concludes that the religions of Australia are made up of two heterogeneous systems, superimposed one upon the other, and consequently derived from a double origin. On the one hand, there were ideas relative to totems and spirits, which had been suggested to men by the sight of certain natural phenomena. But at the same time, by a sort of intuition as to the nature of which he refuses to make himself clear,[965] the human intelligence succeeded at the first onset in conceiving a unique god, creator of the world and legislator of the moral order. Lang even estimates that this idea was purer of foreign elements at the beginning, and especially in Australia, than in the civilizations which immediately followed. With time, it was covered over and obscured little by little by the ever-growing mass of animistic and totemic superstitions. Thus it underwent a sort of progressive degeneration up to the day when, as the effect of a privileged culture, it succeeded in coming into its own and restated itself again with more force and clarity than it had in the first place.[966] But the facts allow neither the sceptical hypothesis of Tylor nor the theological interpretation of Lang.
