+691+. In early societies demons have not individual names. In savage societies there are malefic deities, with individual names, connected with sicknesses and other ills; but such deities are not demons. Demons do not enter into friendly social relations with men,[1178] and observation of experiences is not carried so far as to assign every ill to a separate author. In more advanced societies, as, for instance, the Babylonian,[1179] demons are divided into classes according to their various lines of activity, and to these classes names are given. If some individual demon, representing a particular ill, becomes specially important, it may receive an individual name. In general, the demonic name-giving follows the theistic, but lags behind it. Clan gods have at first some such appellation as Old One, Grandfather, or a descriptive epithet (as among some American Indian tribes), and later, Lord, Lady, Mighty One, Exalted One; in process of time they receive proper names, which must have arisen at a relatively early period, since the meaning of the names of most of the old deities was to the ancients, as it is to us, unknown. In the case of the demonic world this development has not been carried so far, for the reason stated above, namely, that these beings, unlike gods, have not become real citizens of the communities with which they are connected. +692+. In like manner the organization of demons has not kept pace with that of gods. In most regions they have remained a mob, every individual pursuing his way independently. It is only in advanced cults that they form a community with a head. In China and Persia the sharp division of supernatural forces into two classes was the outcome of great religious reformations that followed the usual savage chaos of the hordes of demons. The Jewish demonology (probably influenced by the Persian) chose for the head of its kingdom of evil an old god (the Satan) or the similar figure Azazel.[1180]
