Implicit in the "no man can serve two masters" argument is that the woman, not the man, is master in the home. Or at least that the man and woman's mastery is equal over those in their charge.
From the man's point of view, then,
monogamy demands that he serve two masters — his god and his wife — if not his wife alone.
Let's say it out loud then (and
@andrew please correct me if I've misunderstood):
People believe than women are by their Maker's design the masters of their husbands.
Some further thoughts then:
Egalitarianism I suppose demands at the very least that a wife and husband are each master of the other (if such a thing can exist) or that there is no real master in the home.
- If they're both master then the children serve two, again violating the dictum. This two-headed thing is not how power really works but if you lack real power then the fantasy of benignly shared power is a mollifying distraction.
- If neither is master then the state is master — an arrangement the state has every reason to encourage by teaching monogamy and weakening clans (oops, "extended" families — as if the tribe is somehow not the family's natural shape).
In a Westernized state, then, monogamy is reality — the regime — and egalitarianism is the fantasy that makes it tolerable.
No wonder people are so committed to the arrangement and prickly about polygamy. Who wants to admit they lack fundamental power?
