If the great invisible gods are thus supposed to die, it is not to be expected that a god who dwells in the flesh and blood of a man should escape the same fate. Now primitive peoples, as we have seen, sometimes believe that their safety and even that of the world is bound up with the life of one of these god-men or human incarnations of the divinity. Naturally, therefore, they take the utmost care of his life, out of a regard for their own. But no amount of care and precaution will prevent the man-god from growing old and feeble and at last dying. His worshippers have to lay their account with this sad necessity and to meet it as best they can. The danger is a formidable one; for if the course of nature is dependent on the man-god’s life, what catastrophes may not be expected from the gradual enfeeblement of his powers and their final extinction in death? There is only one way of averting these dangers. The man-god must be killed as soon as he shows symptoms that his powers are beginning to fail, and his soul must be transferred to a vigorous successor before it has been seriously impaired by the threatened decay. The advantages of thus putting the man-god to death instead of allowing him to die of old age and disease are, to the savage, obvious enough. For if the man-god dies what we call a natural death, it means, according to the savage, that his soul has either voluntarily departed from his body and refuses to return, or more commonly that it has been extracted or at least detained in its wanderings by a demon or sorcerer.(764) In any of these cases the soul of the man-god is lost to his worshippers; and with it their prosperity is gone and their very existence endangered. Even if they could arrange to catch the soul of the dying god as it left his lips or his nostrils and so transfer it to a successor, this would not effect their purpose; for, thus dying of disease, his soul would necessarily leave his body in the last stage of weakness and exhaustion, and as such it would continue to drag out a feeble existence in the body to which it might be transferred. Whereas by killing him his worshippers could, in the first place, make sure of catching his soul as it escaped and transferring it to a suitable successor; and, in the second place, by killing him before his natural force was abated, they would secure that the world should not fall into decay with the decay of the man-god. Every purpose, therefore, was answered, and all dangers averted by thus killing the man-god and transferring his soul, while yet at its prime, to a vigorous successor.
