+390+. All important members of the human body have been regarded as to a greater or less extent sacred, their importance depending on their subservience to man's needs. The head of an enemy gives the slayer wisdom and strength; an oath sworn by the head or beard of one's father is peculiarly binding; the heart, when eaten, imparts power; a solemn oath may be sworn by the sexual organs. In no case does the sacredness of an object necessarily involve its worship; whether or not it shall receive a true cult depends on general social considerations. +391+. Though phallic cults proper cannot be shown to be universal among men, they have played a not inconsiderable part in religious history. They appear to have passed through the usual grades of development--simple at first, later more complicated. The attitude of savages and low communities generally, non-Christian and Christian, toward the phallus, suggests that in the earliest stage of the cult some sort of worship was paid the physical object itself considered as a creator of life; satisfactory data on this point, however, are lacking. It was at so early a period that it was brought into cultic connection with supernatural beings that its initial forms escape us. +392+. It seems not to exist now among the lowest peoples. There are no definite traces of it in the tribes of Oceania, Central Africa, Central Asia, and America. The silence of explorers on this point cannot indeed be taken as proof positive of its nonexistence; yet the absence of distinct mention of it in a great number of carefully prepared works leads us to infer that it does not play an important part in the religious systems therein described.[714] It seems to require, for its establishment, a fairly well-developed social and political organization. Some of the tribes named above have departmental deities, mostly of a simple sort, but apparently it has not occurred to them to isolate this particular function, which they probably regarded as a familiar part of the order of things and not needing special mention. The gift of children was in the hands of the local god, a generally recognized part of his duty as patron of the tribe, and all sexual matters naturally might be referred to him. Also, as is remarked above, in certain tribes there was no knowledge of the connection between the birth of children and the union of the sexes,[715] and such tribes would of course ascribe no creative power to the phallus. +393+. The best example of a half-civilized phallic cult is that which is now practiced in Yoruba and Dahomi, countries with definite government and institutions. The cult is attached to the worship of a deity (Elegba or Legba), who appears to be a patron of fertility; the phallus occupies a prominent place on his temples, and its worship is accompanied by the usual licentious rites.[716] These are expressions of popular appetite, and it does not appear that the cult itself is otherwise religiously significant.
