Armed with this hypothesis the eye is quick "to see that it brings with it the power of seeing," and to impose its own forms and schemata on the phenomena offered to its observation. The "animist" ill-acquainted with the savage's language and modes of thought; excluded from those inner "mysteries" which figure in nearly every savage religion; confounding the symbolism, the popular mythology, and also the corruptions, distortions, and abuses which are the parasites of all religion, with the religion itself, can easily come away with the impression that there is nothing but ghost-worship, priestcraft, and superstition, no conception whatever of a personal "Power that makes for Righteousness." If Protestants have almost as crude an idea of the religion of their Catholic fellow-Christians with whom they live side by side, and converse in the same language, if they are so absolutely dominated by their own form of religious thought, as to be as helpless as idiots in the presence of any other, can we expect that the ordinary British traveller, "brandishing his Bible and his bath," strong in the smug conviction of his mental, moral, and religious preeminence, will be a very sympathetic, conscientious, and reliable interpreter of the religion of the Zulu or the Andamanese? The fact is that without a preliminary hypothesis he would see nothing at all except dire confusion. But an assumption such as that of "animism," has the selective power of a magnet, drawing to itself all congruous facts and little filings of probability, until it so bristles over with evidence that a hedge-hog is easier to handle. But before discussing the relation of this assumption to existing facts and so bringing it to an _à posteriori_ test, let us examine its _à priori_ supports.
