A fool notices that bringing children into the world facing disaster is not a wise choice, then convinces himself that it couldn't be wrong because it feels so good.

You don't have to be foolish like that.

The idea of a "biological imperative" that constitutes a reason why you should reproduce is nonsense. There is a biological tendency to reproduce, which exists for well-known evolutionary reasons, but a tendency to do something is not a reason to do it. I have a tendency to mislay things and forget where I put them, but that is no reason why I ought to forget.

Anything that makes you focus most of your attention on the well-being of one specific other person — which is almost guaranteed to call for more money than you can gain honestly — is a road to cheating or abusing people. It is wiser not to set foot on that path!
