+656+. This specialization of functions is possibly in part an elevation of the old scheme of spirits according to which every object in the world was conceived of as inhabited or controlled by some spiritlike being. It is not probable that the departmental gods are always developed directly out of spirits--they appear sometimes to belong rather in the clan system, are anthropomorphic, human, lending themselves more readily than spirits do to human intercourse.[1103] It is true that the lower cults of animals and spirits persist alongside of the higher religious forms, and the various groups often appear to blend with one another, as is generally the case in transitions from one system of thought to another. +657+. Deities with this sort of specialized functions appear in all parts of the world and at various periods of culture. The particular sort of specialization differs according to climatic conditions and social organization--that is, it depends in any community on the nature of the phenomena that touch the life of the community closely. But the general principle remains the same--it is the effort to penetrate more deeply into the nature of the supernatural Powers, and to enter into more intimate and helpful relations with them; it is the beginning of a more practical study of theology proper. +658+. A somewhat low and vague form of specialization of function is found in Melanesia, where certain beings appear as patrons of work.[1104] These are said by Codrington to be ghosts, yet to be prayed to just as if they were gods; and in fact, being men with indefinitely great powers, they can hardly be distinguished from such deities as Daramulun and Unkulunkulu, except in the fact that their function is specific. In Australia the published reports do not describe departmental gods proper, with the possible exception of an undefined being in the North. A more developed scheme exists in Polynesia. In New Zealand there were deities of food-planting and of forests.[1105] The highest point of Polynesian civilization seems to have been reached in the Hawaiian Islands, where, besides several great gods, there were deities of the sky, the sea, winds, and lightning, of agriculture, and of various occupations and professions, such as fishing, and even robbing.[1106]
