12. Existence under such conditions must have been as unendurable as that of poor children who have been terrified by silly nurses into a belief in ogres and a fear of dark rooms, had there not existed real or imaginary defences against this array of horrible beings always ready to fall on unfortunate humanity in all sorts of inexplicable ways and for no other reason but their own detestable delight in doing evil. These defences could not consist in rational measures dictated by a knowledge of the laws of physical nature, since they had no notion of such laws; nor in prayers and propitiatory offerings, since one of the demons' most execrable qualities was, as we have seen, that they "knew not beneficence" and "heard not prayer and supplication." Then, if they cannot be coaxed, they must be compelled. This seems a very presumptuous assumption, but it is strictly in accordance with human instinct. It has been very truly said[AD] that "man was so conscious of being called to exercise empire over the powers of nature, that, the moment he entered into any relations with them, it was to try and subject them to his will. Only instead of studying the phenomena, in order to grasp their laws and apply them to his needs, he fancied he could, by means of peculiar practices and consecrated forms, compel the physical agents of nature to serve his wishes and purposes.... This pretension had its root in the notion which antiquity had formed of the natural phenomena. It did not see in them the consequence of unchangeable and necessary laws, always active and always to be calculated upon, but fancied them to depend on the arbitrary and varying will of the spirits and deities it had put in the place of physical agents." It follows that in a religion which peoples the universe with spirits of which the greater part are evil, magic--i.e., conjuring with words and rites, incantations, spells--must take the place of worship, and the ministers of such a religion are not priests, but conjurers and enchanters. This is exactly the state of things revealed by the great collection of texts discovered by Sir H. Rawlinson and G. Smith. They contain forms for conjuring all the different kinds of demons, even to evil dreams and nightmares, the object of most such invocations being to drive them away from the habitations of men and back to where they properly belong--the depth of the desert, the inaccessible mountain tops, and all remote, waste and uninhabited places generally, where they can range at will, and find nobody to harm.
