against the utterance of any impure word that might produce an ill-omened condition of mind in the congregation. Of this development of the idea of spiritual from that of ritualistic purity, the language of certain of the higher races affords the same indication as we find in the Basuto phrase: the Latin “purus” and the Greek καθαρός and φοῖβος themselves have an original material or physical significance; the blood that is shed and the unburied corpse emit a “miasma,” a defiling atmosphere charged with dangerous spirits, and the same word μίασμα comes to denote a spiritual corruption of the soul: touching a corpse is called “sin” in the Zend-Avesta;[115.1] and it is significant that the same word which is used to express the material idea of impurity in the Old Testament in the earlier books of the Law is employed in the later and more advanced ethical vocabulary of the Bible for a real sin against God as understood in the modern sense. {116} Again, we have other evidence besides the linguistic that the earliest conception of sin which we can call spiritual was still half-materialistic, and was still closely allied to that of bodily impurity. In the theory of earlier ritual, the sin can be washed away like a physical taint, the atonement takes the form of certain lustrations, and repentance is not considered necessary as a moral condition of release. And to the same middle stage of development belongs the process known as the transference of sin, whereby the sin can be extracted as if it were a substance from the person of the sinner and transferred into another man or animal or even an inanimate object. Think of sin as an inner vapour or exhalation and the idea of quasi-mechanical transference is intelligible.[116.1] It no doubt belongs to a comparatively early {117} period of savage religion. Among the Atkans, for instance,[117.1] we hear of such a release as this: the sin, which in this case was a gross violation of a natural law of the sex-instinct, was made to enter into certain weeds which were worn about the person, and then, under a clear sun were carefully thrown away, the sun himself being called to witness the act of transference. In the ancient Peruvian Church, the shaking off of evils was a great public festival: bands of warriors marched forth crying out, “Go forth, all evils,” and then bathed in the river, while the people shook out their clothes from the doors.[117.2] A similar record speaks of the Inca praying to the river-god to bear away his sins, which he had confessed in the sight of the sun. And during the Peruvian purification a similar rule prevailed to that which was noticed above, that all abusive language and strife was to be avoided. Or again, the {118} belief that the sin is an evil spirit that can be induced to find another living-lodgment, suggests the scapegoat, a familiar figure in Leviticus and in Greek ritual, the animal who bears away with it into the wilderness the sins of the people, or is put to
