The more one thinks of a person's life in the world the more one comes to understand that it is not very different from the life of a child. The child takes a fancy to a doll and then gets tired of the doll and takes a fancy to another toy. And when the child takes a fancy to the doll or the toy, he or she thinks it the most valuable thing in the world, and then there comes a time when the child tears up the doll and destroys the toy.
