Parenting - Is There a Delusion?

Our minds are designed to have delusions. And you could argue that some of those delusions might, in fact, be useful. i think the simplest and clear est example of this is in the realm of parenting and parenthood. When i my own daughter was born a many years ago, the day she was born, i was tor the most special day of my own life. Now clearly, when i thought about that, rationally, that has to be a delusion. But it turns out that's one of many kinds of delusions that may be irrational or non rational, but in fact, might have a profoundly salutary role for us and our species.
