Philosophy and Children

I just found this on the NY Times website. It is an article discussing the possibilities of children being able to think abstractly and do philosophy. It is philosophy done through children's books. I thought it was interesting that one of the books being discussed philosophically was The Giving Tree.

Spontaneous Spirit ?

This spirit of given that is further with every gift one gets and then gives, does it matter where it came from? Should we concern are ourselves with the origin of the first gift which began this now ongoing exchange? If this spirit is more of spontaneous eruption inside of the individual is there significance in when it happens? So can there maybe be more value placed on gift that is given at random than one which is brought on by occasions, such as kind of potlatch or a birthday? The question of value is important in trying to determine how one should reciprocate.
