By reason of paucity of data it is difficult to determine the precise characters of various Celtic, Slavic, and Germanic deities whose names appear in the records. They are gods of clans and of departments of nature; none of them can properly be reckoned among the great gods.[1162] +683+. _Division into good and bad Powers._ Among many savage and half-civilized peoples we find that a distinction is recognized between good and bad ghosts and spirits--a distinction at first vague, based on passing experiences in which all the fortunes of men, favorable and unfavorable, are referred to these beings. Their morals are those of the human communities with which they are connected: they may be amiable or malignant, beneficent or revengeful, but the ethical element in their characters and deeds is not distinctly recognized and is not made the basis of the distinction between the two classes. The world is seen to be full of Powers that make for weal or for woe--a conception that contains the germ of all the later development but is at first nebulous. +684+. In a somewhat higher form of culture these two classes of Powers may be unified respectively into, or replaced by, two gods, one helpful, the other harmful. Such appears to be the scheme of the Masai, who have their black god and red god.[1163] A Californian cosmogonic myth describes a nonmoral conflict of work between the good "Creator" and the malicious Coyote.[1164] A real unification appears, however, to be rare; it supposes in fact a degree of reflection and organization that we should not expect to find among lower peoples. The story, for example, that has been told of a well-developed dualistic system of the Iroquois is based on a misconception.[1165] Dualism proper is not recognizable among the savages of America, Polynesia, Asia, or Africa.[1166] In the Old Testament prior to the sixth century B.C. the spirits, good and bad, which are not essentially different from those we find among the lower tribes, are massed under the control of Yahweh, and do his bidding without moral reflection; when he sends a lying spirit into the mouth of Ahab's prophets[1167] this spirit goes without malice merely to perform the will of the supreme god. This massing of all spirit Powers under the control of one god is a step toward unity and clearness in the conception of the government of the world. +685+. At a later stage of social growth there appears the conception of a cosmic struggle, the conflict between the natural forces that tend to disorder and those that tend to order. Philosophical reflection led to the supposition of an original chaos, a medley of natural forces not combined or organized in such a way as to minister to the needs of human life; and a similar conception of conflict may have arisen from observation of the warring elements at certain seasons of the year.
