82:4.2

Primitive marriage was an investment, an economic speculation; it was more a matter of business than an affair of flirtation. The ancients married for the advantage and welfare of the group; wherefore their marriages were planned and arranged by the group, their parents and elders. And that the property mores were effective in stabilizing the marriage institution is borne out by the fact that marriage was more permanent among the early tribes than it is among many modern peoples.
