The Importance of Being Free From Attachment

Psychologically, we are the world. And the world is us, each one of us. Our responsibility is something global, not just for one's family, for one's children; those are important, but we are responsible for the whole of mankind because we are mankind. Can one actually be free of all attachment?   What will persuade you, what will make you, what will drive you, what will influence you to change?   Thought by its very nature is fragmentary, and we, our struggle, the whole of our being, is the movement of thought.  Technological, surgical, engineering, scientific knowledge is necessary, but the knowledge that has psychologically accumulated through millennia as human beings, is that necessary at all? Can this movement of thought end?
