It has less to do with education, than with the product of education (which is leaving an agrarian or labor based system). When you become educated, and free yourself from physical labor, you no longer need many sons. Many wives can efficiently produce many sons. If you do not need many sons, many wives are superfluous. You can see it as a noble pursuit, I see it simply as what works. Good, bad, moral, immoral, have very little to do with it, really. We humans can call almost anything "good" if it works for us. We're very adaptive and creative.
I think our instinct is to adapt to what is around us- since we are flexible creatures, and have an extremely long period of immaturity, for an animal. So we would be taught by our society to pair bond monogamously when it suited our society, and we would be taught something if else, if something else was more practical (imo).
All I was really saying was some animals have evolved a "moral" monogamy just because it works. Just as we "evolve" socially to have monogamy when it works. And when it doesn't work, we don't have it (or so it would appear) |
