Adults often assume that most learning is the result of teaching and that exploratory, spontaneous learning is unusual. But actually, spontaneous learning is more fundamental.

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.

I'm afraid the parenting advice to come out of developmental psychology is very boring: pay attention to your kids and love them.

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 best scientific way to discover if one factor influences another is to do a controlled experiment.

Instead of just saying, "I love my baby and I pick him up because he's adorable and it's so nice to cuddle with him," we practice attachment parenting. We let our children play outside and have age-appropriate freedoms and are labeled free-range parents.

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.
