We need all of us, whatever our background, to constantly examine the stories inside which and with which we live. We all live in stories, so called grand narratives. Nation is a story. Family is a story. Religion is a story. Community is a story. We all live within and with these narratives. And it seems to me that a definition of any living vibrant society is that you constantly question those stories. That you constantly argue about the stories. In fact the arguing never stops. The argument itself is freedom. It's not that you come to a conclusion about it. And through that argument you change your mind sometimes. And that's how societies grow. When you can't retell for yourself the stories of your life then you live in a prison. Somebody else controls the story.
—Salman Rushdie
Model-dependent realism (Hawking)
According to the idea of model-dependent realism...our brains interpret the input from our sensory organs by making a model of the outside world. We form mental concepts of our home, trees, other people, the electricity that flows from wall sockets, atoms, molecules, and other universes. These mental concepts are the only reality we can know. There is no model-independent test of reality. It follows that a well-constructed model creates a reality of its own.
Stephen Hawking
