One of the most distinctive evolutionary features of human beings is our unusually long, protected childhood.

Some people say that parents don't matter, and that's not true at all. The irony is that we pay attention to all these things that don't matter, and not to what does matter, such as parents having enough resources to provide an environment where their children have both security and freedom.

Preschool kids learn best when exploring, but kids in school learn best when they do things, interacting with a master. Unfortunately, our schools don't do much of either. Also, kids do need to learn how to deal with technology, and online education and otherwise using electronic devices as learning tools facilitates that.

Caring, whether for children or the dying, shouldn't be instrumental. It should be an intrinsic, moral good.

Philosophers and psychologists have long puzzled over the question of how we know as much as we do despite our limited experiences. One way is to see how children learn. Another example is consciousness. The concept is usually explored by armchair academics. Looking at kids expands our conceptions of consciousness.

There is a tension between our desire to get our kids to turn out a particular way versus letting them develop to be their own person. If there were a pill that would make my child turn out the way I wanted, I'm not sure I'd take it.

Being a grandmother is a wonderful thing, so my advice is skip the children. Go straight to the grandchildren.
