Some think of fit in advance, in other cases it is just a general cultural value because, apparently, it is economically useful.
But judging people’s motivations isn’t going to get us any closer to solving the problem. Better provide them with real solutions.
And by the way, altruism is fine and dandy, but it is unreasonable to expect someone to sacrifice their own wellbeing (not comfort, mind you, but actual wellbeing) for the “good of the species.” It flies in the face of what’s evolutionarily adaptive and is about as smart as expecting priests to remain celibate. I though we were the reality-based community, here.
I don’t know about that. Apparently, people do judge motivations, in fact, teens are often counseled to make lists of their motivations for having children and then judge them. I’ve done this myself, and was surprised to find how many reasons were ego based (try it sometime). Sorry, you can’t get me on board for thinking that bringing a person into the world in order to have a Mini-me be my caretaker is ethically justified and is better than the other options out there (especially adoption). I think it’s really more often just an afterthought. It doesn’t make much sense that people would have children to help care for them when they are elderly for evolutionary reasons when they usually need care long after they are able to breed… unless you put the kids to work.
Your later point doesn’t deny that it is selfish, just natural- which is what I said. Consider ends and means in the kind of world you want to live in. We are not social Darwinists. I’m actually kind of surprised you would be so defensive about it. We eat meat too, but that doesn’t mean that it’s “good.” We need to be able to admit when we have less than ethical- less than desirable, motivations to some of the actions we deem necessary, and especially when admitting that sometimes they are not even necessary at all. We’re talking about making someone exist here.
Which leads me to the implications of truly adopting Paul Kurtz’s planetary ethics. When you truly realize that we are all connected and one family, then I believe you can authentically perceive the adoption of another person’s child as already taking in one of your own. There’s a truly impressive and noble act IMO. (Okay… simmer down now or I’m going to have to go down to Hot Topic and buy some red underwear to keep up.)
