Material necessity founded marriage, sex hunger embellished it, religion sanctioned and exalted it, the state demanded and regulated it, while in later times evolving love is beginning to justify and glorify marriage as the ancestor and creator of civilization's most useful and sublime institution, the home. And home building should be the center and essence of all educational effort.

Mating is purely an act of self-perpetuation associated with varying degrees of self-gratification; marriage, home building, is largely a matter of self-maintenance, and it implies the evolution of society. Society itself is the aggregated structure of family units. Individuals are very temporary as planetary factors—only families are continuing agencies in social evolution. The family is the channel through which the river of culture and knowledge flows from one generation to another.

The home is basically a sociologic institution. Marriage grew out of co-operation in self-maintenance and partnership in self-perpetuation, the element of self-gratification being largely incidental. Nevertheless, the home does embrace all three of the essential functions of human existence, while life propagation makes it the fundamental human institution, and sex sets it off from all other social activities.

Marriage was not founded on sex relations; they were incidental thereto. Marriage was not needed by primitive man, who indulged his sex appetite freely without encumbering himself with the responsibilities of wife, children, and home.

Woman, because of physical and emotional attachment to her offspring, is dependent on co-operation with the male, and this urges her into the sheltering protection of marriage. But no direct biologic urge led man into marriage—much less held him in. It was not love that made marriage attractive to man, but food hunger which first attracted savage man to woman and the primitive shelter shared by her children.

Marriage was not even brought about by the conscious realization of the obligations of sex relations. Primitive man comprehended no connection between sex indulgence and the subsequent birth of a child. It was once universally believed that a virgin could become pregnant. The savage early conceived the idea that babies were made in spiritland; pregnancy was believed to be the result of a woman's being entered by a spirit, an evolving ghost. Both diet and the evil eye were also believed to be capable of causing pregnancy in a virgin or unmarried
