I have a far deeper question to pose. After I give my answer to this one of course. Hopefully there is enough logic in it for Satanboy.
A: I have thrown this topic around in my mind for some years now. Not the why have kids, more the why have kids and add to overpopulation etc... I was close to coming to the same opinion as you, although I have a very maternally driven wife so that possibly helped to balance my reasoning a little as I tend to be a pessimist when it comes to the fate of the world at the hands of humans. My final answer however, is that I know I will create kids that will contribute to this world positively. Not only genetically but also through their upbringing. I feel it is my duty not to simply procreate to further the human race, as its quite obvious that we are doing just fine on the numbers side. But to ensure that the Gene pool is not watered down by the poor, illiterate, uneducated, unfit, etc... Basically those that live in circumstances that will keep their kids back and perpetuate the weakness.
The issue is that; if everyone that has the intelligence to realize that having kids adds to the population problem, stops procreating, then we are shooting ourselves in the evolutionary foot. As it is, there are too many people that are unfit to have kids, popping them out at a furious rate. If we do not do something to contribute to the philosophical balance in the situation, then we are logically being irrisponsible to both the planet and our species. The more people out there that are intelligent enough to contribute to the collective voice of curbing population the better.
Also knowing that I will impart intelligence, reasoning and imagination etc... on my kids, there is always the possiblity that one of my kids contributes to the solving of some major global problem in the future. Perhaps not mine specifically but its a numbers game really, if all the people with the right parenting skills and genetics stop procreating, then we all but eliminate the chance that we might one day solve global warming, overpopulation, needless wars, famine etc... If we all procreate we increase our chances to not only save ourselves but the planet, from ourselves.
I have decided against posting my other question. Perhaps at a later date as a forum thread when I have the details fleshed out fully.
The problem with most peoples answers here is that everyone is giving retrospective answers. Dont say, I now have them and its the best thing ever, although I respect that view completely. From the direction that this threads question was asked, he is not asking for the why you would choose to have kids again, after the fact. He is asking what drove you to decide to have them in the first place. Hoping for logical answers as apposed to the usual emotional ones. Again the emotional reasons are perfectly fine, my wife is emotionally driven and I am logically driven so we balance each other nicely. Allowing me to view things from both sides. I think satanboy is just logically driven and is looking for a logical basis for having kids as apposed to the obvious and very valid reason, that it just feels right to want one.
