But seriously, why is our drive to have children so powerful? Now, you may say its because children can be enjoyed for their own sake. That may be true for some, but clearly at least some human men are prone to promiscuity and want children without having to raise them. So the desire for children exists apart from wanting to raise children.
I hate to bring a Sci-fi book into this, since it makes me look like an uber-nerd (which I am ), but has anyone ever read the Dune sequels? Frank Herbert explores the idea that we may be able to somehow share the consciousness of our descendants after we are dead, continue experiencing life through them, etc. He sees this as having a biological basis, i.e. we actually perserve our consciousness and past memories in our DNA, and can once again become conscious, as long as our DNA lives on.
What do you all think?
