In reality, however, sexual freedom is an entirely different mat ter from the liberty of parenthood, and between the two there enter some interesting institutions and legal rules.
And this brings us to the important point. Physiological pater nity, the begetting of a child, is not, as a rule, sufficient and may even be irrelevant in determining social fatherhood. In fact native peoples have naturally but an imperfect idea of the mechan ism of procreation. Some (Central Australians, certain Mela nesians, a few African tribes) attribute the child to the agency of spiritual beings; others again (Ba-Ila, Rossel Islanders, some Australian tribes) over-emphasize the man's share. But in all cases, where the subject has been competently investigated, we find that the mechanism of procreation is conceived in a manner in which some biological knowledge is arbitrarily mixed up with animistic beliefs. This doctrine stands in a definite relation to the kinship ideas and legal principles of a community. Invariably
also the bond of kinship, believed to be established by the act of procreation, bodily or spiritual, is of an individual nature and fatherhood has at times to be reaffirmed by a special legal cere mony, also individual.
Wherever there is an attempt to cause or prevent conception by religious and magical rites, these refer always to an individual mother and child. The mother becomes usually subject to tabus during gestation which she keeps individually and of which her husband of ten takes a share. The welfare of the child concerns its own mother and father even before it is born. At birth again various social, magical and moral rules separate the mother from her husband and isolate her with her child. The few female relatives who of ten assist her are her nearest individual kins women. There is no transformation of an individual birth into a group birth—by legal fiction or ritual—but on the contrary there is a social imposition of individual burdens, responsibilities and sentiments upon the real mother. The father, though very much in the shadow, participates through customs of the couvade (q.v.) type, vigils and tabus in his wife's confinement, and this he also does individually.
