That struck a nerve, in class. Several students said they do not intend to have children, though none admitted to not enjoying life.
I'm trying to recall my own feelings about the prospect of parenting when I was a 20-year old undergraduate. I think I had every intention then of doing it eventually, someday, but certainly not anytime soon. And that's how it happened: late marriage, later family, and yet all too soon now the nest will be empty again. I can't imagine what those years would have been like without our girls, and don't want to. I share Russell's attitude about the complexity, the delights, and the deep gratification of "parental feeling":
There is, first and foremost, sheer animal affection, and delight in watching what is charming in the ways of the young. Next, there is the sense of inescapable responsibility, providing a purpose for daily activities which skepticism does not easily question. Then there is an egoistic element, which is very dangerous: the hope that one's children may succeed where one has failed, that they may carry on one's work when death or senility puts an end to one's own efforts, and, in any case, that they will supply a biological escape from death, making one's own life part of the whole stream, and not a mere stagnant puddle without any overflow into the future. All this I experienced, and for some years it filled my life with happiness and peace. AutobiographyI was trying to talk in class about that dangerous "egoistic element," about the value of that feeling of being tangibly invested in our children's future, hoping to make a constructive contribution to their flourishing and caring about it in more personal terms than I imagine the childless do... but at the same time resisting the selfish impulse to (as Emerson put it) "make another you. One's enough."
In other words, the kids are alright. "Cannot we let people be themselves and enjoy life in their own way?" So, maybe two, maybe one, maybe none: there are enough of us, we can afford a few happily childless adults. I'm just glad I'm not one of them.
