I just do not get how this "ideal" relates to marriage.
I don't think he was specifically, CT. I followed your conversation as it seemed to be the most promising for actual progress on the issue. I believe he was stating that naturally (in the common understanding of the word without redefinition) men and women together conceive children, and that that alone is no guarantee that said children will be perfect little adults, however, contemporary context needs to be addressed when looking at the "history" of child rearing. Anthropology tells us that, pretty much up until perhaps the last few centuries men and women had children not for the sake of raising wonderful little copies of themselves, or a notion of being cognitive of some passing on of one's genes, but rather mostly, or in most cases outside of aristocracy, men and women bore children for work. Yes, we created children so they could work the fields, help on the hunt, you get the picture. Fast forward to the last hundred years, and even then we can see this pattern in a lot, (although starting to change) of families in all parts of the world including here in western society. Having children in poorer to middle class environments was seen as a way to increase your total family output over time. In higher income brackets children were seen as a novelty, a status of sorts, a way to keep up the family pedigree. Today, children are born out of love, and in most cases (Well ideally most cases) we have them to pass on our genes, to further our legacy, to adore them, and to benefit from their lives.
In a sense, if we're being truthful, children have gone from being born into what is essentially slavery, to now being the slave-masters. We the parents, have become their slaves. Ironic isn't it?
of course the topic deserves a much larger discussion, and my one paragraph (I hope is understood) is merely a summary of my opinions on the topic, but nowhere near as comprehensive as it needs to be to be better understood, but I think you get the point I was trying to make. In some ways I agree with you on this subject that marriage, like child rearing has no definitive history or purpose. But as a society, I think that we have a duty and a responsibility to determine how WE ourselves proceed into the future on both aspects of the debate.
