It is important to remember that we have come to regard marriage as defined primarily by parenthood. Now social parent hood in native ideas, behaviour, custom and law is not affected by these various forms of relaxation just described. The children are reckoned as belonging to the legal husband, and in this as in many other ways—economic, legal and religious—these tempo rary relaxations do not seriously disturb the marriage relationship. It must be realised with regard to fatherhood that even where the main principles of physiological procreation are known, savages do not attribute an undue importance to actual physiological paternity (see KINSHIP). It is almost always the husband of the woman who is considered the legal father of her children, whether he be their physiological father or not..
It is not correct to regard the institutions of temporary and limited partnership described above, such as the pirrauru of C. Australia or the protracted exchange of partners among the Eskimo, as concubinage.
hand, in certain communities, of which Ancient Greece is a not able example, i.e., "hetairism," prostitution in a higher and more refined form, allowed some women to devote themselves Ito cul tural pursuits and to associate with men more freely than was possible to those legally married.
On the whole it is rather a subsidiary institution than either a relaxation or a form of sexual preparation. Unlike the other forms of sexual licence, prostitution is neither directly correlated with marriage nor does it affect its integrity so seriously as do the forms of matrimonial relaxation which involve both husband and wife.
In the vast majority of human societies the individual family, based on monogamous marriage and consisting of mother, father and children, forms a self-contained group, not necessarily how ever cut off from society. Within the household there is a typical scheme of division in functions, again almost universal. By virtue of natural endowment the wife has not only to give birth to and nourish the children, but she is also destined to give them most of the early tender cares: to keep them warm and clean, to lull them to sleep and soothe their infantile troubles. Even in this the hus band often helps to a considerable degree, prompted by natural inclination as well as by custom. This latter often imposes upon him duties and ritual manifestations such as taboos during the pregnancy of his wife and at childbirth, and performances at the time of confinement, of which the couvade (q.v.) is the most striking example. All such obligations emphasize the father's responsibility and his devotion to the child. Later on in the educa tion of offspring both parents have to take part, performing their respective duties, which vary with the society and with the sex of the children.
