+164+. About the motives of early man in the adoption of these customs of excision we have, of course, no direct information; but some later usages favor the explanation suggested above. The operations performed on females are obviously dictated by considerations of convenience or propriety in coition. Various means are adopted of increasing the pleasure of sexual intercourse (in Indonesia and elsewhere).[314] These procedures are purely animal, nonmoral, and without ulterior design; there is no thought of progeny or, in general, of preparation for marriage--the frame of mind is appropriate to the lowest grade of life. +165+. In the course of time, however, all such customs tend to become sanctified and to take on new meanings. When the importance of circumcision was generally felt, it was natural that it should be performed at puberty and at initiation.[315] It would thus come to be regarded as an introduction to the tribal life--not as preparation, but as a custom established by unwritten law. Its origination would be put far back in the past and sometimes ascribed to supernatural personages--the Central Australians refer it to the mythical ancestors, the later Jews to the command of the national deity issued to the legendary or mythical ancestor Abram.[316] Under certain circumstances it might become a tribal mark; the Hebrews thus distinguished themselves from their neighbors the Philistines, and "uncircumcised" was a term of reproach.[317] +166+. Apart from its use in initiation the cultic rôle of circumcision has been small. It does not appear as an element in the worship of any deity, neither in that of such gods as Osiris, Tammuz, Adonis, Attis, nor in that of any other. It is not represented in ancient records as a devotion of one's self or an assimilation of one's self or of a child to the tribal or national god. Its performance is generally a religious duty, as is true of every established custom, but this fact throws no light on its origin. The prepuce is sometimes treated as an amulet or in general as a magically powerful or sacred thing; but many other parts of the body (hair, finger nails, etc.) are so treated. +167+. In the higher religions circumcision is generally viewed as an act of physical purification or as a symbol of moral purification. The former view, perhaps, prevailed in Egypt, though on this point the records appear to be silent.[318] The latter view is that of the Old Testament prophets and the New Testament.[319] It has now ceased to have any effective religious significance, and is retained in some communities merely as a national social tradition or as an ancient divine ordinance.
