(M14) Not so with the purificatory theory. It is obviously applicable to some of the facts, and apparently consistent with them all. Thus we have seen that sick men make a vow to walk over the fire, and that sick cattle are driven over it. In such cases clearly the intention is to cleanse the suffering man or beast from the infection of disease, and thereby to restore him or it to health; and the fire is supposed to effect this salutary end, either by burning up the powers of evil or by interposing an insurmountable barrier between them and the sufferer. For it is to be remembered that evils which civilized men regard as impersonal are often conceived by uncivilized man in the personal shape of witches and wizards, of ghosts and hobgoblins; so that measures which we should consider as simple disinfectants the savage looks upon as obstacles opportunely presented to the attacks of demons or other uncanny beings. Now of all such obstacles fire seems generally to be thought the most effective; hence in passing through or leaping over it our primitive philosopher often imagines that he is not so much annihilating his spiritual foe as merely giving him the slip; the ghostly pursuer shrinks back appalled at the flames through which his intended victim, driven to desperation by his fears, has safely passed before him. This interpretation of the ceremony is confirmed, first, by the observation that in India the ashes of the bonfire are used as a talisman against devils and demons;(32) and, second, by the employment of the ceremony for the avowed purpose of escaping from the pursuit of a troublesome ghost. For example, in China “they believe that a beheaded man wanders about a headless spectre in the World of Shades. Such spectres are frequently to be seen in walled towns, especially in the neighbourhood of places of execution. Here they often visit the people with disease and disaster, causing a considerable depreciation in the value of the houses around such scenes. Whenever an execution takes place, the people fire crackers to frighten the headless ghost away from the spot; and the mandarin who has superintended the bloody work, on entering the gate of his mansion, has himself carried in his sedan chair over a fire lighted on the pavement, lest the headless apparition should enter there along with him; for disembodied spirits are afraid of fire.”(33) For a like reason Chinese mourners after a funeral, and persons who have paid a visit of condolence to a house of death, often purify themselves by stepping over a fire of straw;(34) the purification, we cannot doubt, consists simply in shaking off the ghost who is supposed to dog their steps. Similarly at a coroner’s inquest in China the mandarin and his subordinates hold pocket handkerchiefs or towels to their mouths and noses while they are inspecting the corpse, no doubt to hinder the ghost from insinuating himself into their bodies by these apertures; and
