The more one thinks of man's life in the world the more one comes to the understanding that it is not very different from the life of a child. The child takes a fancy to a doll and then it gets tired of that doll and wants another toy. But at the moment when it takes a fancy to the doll or the toy it thinks it the most valuable thing in the world; and then there comes a time when it throws away the doll and destroys the toy. And so it is with man; his scope is perhaps a little different, but his action is the same.
