"Polygamy is the ultimate expression of inequality because it means that
many males never get the chance to have a wife and child. And sexual envy has been,
throughout history, among animals as well as humans, a prime driver of violence."
Wish people'd quit misusing the word. That's polygany. Polygamy is actually quite fair.
"...that every human being, regardless of class, colour, culture or creed, is in the image and likeness of God himself."
Well, God and the angels. Verse says "...in our image." Not 'in my image.' And despite this, we still say the natural human form, nude, which would be that of God can be obscene. Go figure.
"And there is a deep connection between monotheism and monogamy, just as
there is, in the opposite direction, between idolatry and adultery. Monotheism and
monogamy are about the all-embracing relationship between I and Thou, myself and one
other, be it a human, or the divine, Other."
Is a deep connection between monogamy and violence too:
"Extramarital Sex
I also examined the influence of extramarital sex taboos upon crime and violence. The data clearly indicates that punitive-repressive attitudes toward extramarital sex are also linked with physical violence, personal crime, and the practice of slavery. Societies which value monogamy emphasize military glory and worship aggressive gods.
These cross-cultural data support the view of psychologists and sociologists who feel that sexual and psychological needs not being fulfilled within a marriage should be met outside of it, without destroying the primacy of the marriage relationship."
