People talked about being a parent, or being a mother or a father. We don't talk about "wiving" our husbands or "friending" our friends, or "childing" our parents. We just talk about being in a relationship with those people. You don't measure whether your marriage was good based on whether or not your husband is better now than he was 10 years ago, or whether your friend is richer than when they first became your friend. The relationships between parents and children is a kind of love, rather than a kind of work.

Young children seem to be learning who to share this toy with and figure out how it works, while adolescents seem to be exploring some very deep and profound questions: how should this society work? How should relationships among people work? The exploration is: who am I, what am I doing?

You read a bunch of books and you get a bunch of how-tos, and you take a bunch of classes and you learn a bunch of techniques. You set yourself goals and benchmarks. I think people have imported that into their experience of taking care of children.

Teaching is a very effective way to get children to learn something specific - this tube squeaks, say, or a squish then a press then a pull causes the music to play. But it also makes children less likely to discover unexpected information and to draw unexpected conclusions.

We fear death so profoundly, not because it means the end of our body, but because it means the end of our consciousness - better to be a spirit in Heaven than a zombie on Earth.

The youngest children have a great capacity for empathy and altruism. There's a recent study that shows even 14-month-olds will climb across a bunch of cushions and go across a room to give you a pen if you drop one.

The largest and most powerful computers are still no match for the smallest and weakest humans.
