P927:2, 83:6.1 Monogamy is monopoly; it is good for those who attain this desirable state, but it tends to work a biologic hardship on those who are not so fortunate. But quite regardless of the effect on the individual, monogamy is decidedly best for the children.
P927:3, 83:6.2 The earliest monogamy was due to force of circumstances, poverty. Monogamy is cultural and societal, artificial and unnatural, that is, unnatural to evolutionary man. It was wholly natural to the purer Nodites and Adamites and has been of great cultural value to all advanced races.
P927:4, 83:6.3 The Chaldean tribes recognized the right of a wife to impose a premarital pledge upon her spouse not to take a second wife or concubine; both the Greeks and the Romans favored monogamous marriage. Ancestor worship has always fostered monogamy, as has the Christian error of regarding marriage as a sacrament. Even the elevation of the standard of living has consistently militated against plural wives. By the time of Michael's advent on Urantia practically all of the civilized world had attained the level of theoretical monogamy. But this passive monogamy did not mean that mankind had become habituated to the practice of real pair marriage.
P927:5, 83:6.4 While pursuing the monogamic goal of the ideal pair marriage, which is, after all, something of a monopolistic sex association, society must not overlook the unenviable situation of those unfortunate men and women who fail to find a place in this new and improved social order, even when having done their best to co-operate with, and enter into, its requirements. Failure to gain mates in the social arena of competition may be due to insurmountable difficulties or multitudinous restrictions which the current mores have imposed. Truly, monogamy is ideal for those who are in, but it must inevitably work great hardship on those who are left out in the cold of solitary existence.
P927:6, 83:6.5 Always have the unfortunate few had to suffer that the majority might advance under the developing mores of evolving civilization; but always should the favored majority look with kindness and consideration on their less fortunate fellows who must pay the price of failure to attain membership in the ranks of those ideal sex partnerships which afford the satisfaction of all biologic urges under the sanction of the highest mores of advancing social evolution.
P927:7, 83:6.6 Monogamy always has been, now is, and forever will be the idealistic goal of human sex evolution. This ideal of true pair marriage entails self-denial, and therefore does it so often fail just because one or both of the contracting parties are deficient in that acme of all human virtues, rugged self-control.
P927:8, 83:6.7 Monogamy is the yardstick which measures the advance of social civilization as distinguished from purely biologic evolution. Monogamy is not necessarily biologic or natural, but it is indispensable to the immediate maintenance and further development of social civilization. It contributes to a delicacy of sentiment, a refinement of moral character, and a spiritual growth which are utterly impossible in polygamy. A woman never can become an ideal mother when she is all the while compelled to engage in rivalry for her husband's affections.
P928:1, 83:6.8 Pair marriage favors and fosters that intimate understanding and effective co-operation which is best for parental happiness, child welfare, and social efficiency. Marriage, which began in crude coercion, is gradually evolving into a magnificent institution of self-culture, self-control, self-expression, and self-perpetuation.
