I would say that purpose is not imposed from the outside; it is generated from the inside. We make our purpose. And there is a kind of dereliction of duty of us humans when we say that the purpose is to be imposed on the outside or found in some book written thousands of years ago. We live in a very different world than we lived in thousands of years ago. There is no question that we have many obligations to guarantee our purposes, one of which is to survive. And that we have to work out for ourselves.
