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.

From an evolutionary perspective children are, literally, designed to learn. Childhood is a special period of protected immaturity. It gives the young breathing time to master the things they will need to know in order to survive as adults.

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 brain knows the real secret of seduction, more effective than even music and martinis. Just keep whispering, 'Gee, you are really special' to that sack of water and protein that is a body, and you can get it to do practically anything.

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

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.

Adults tend to think they have much free will. Kids younger than six are less sure. They may be more realistic!
