Despite my current confidence that minds are brains, I could be convinced otherwise by evidence that
is best explained by the supposition that minds are nonmaterial substances. By far the most powerful
kind of evidence would be observations showing that minds survive the loss of their bodies.
Christians, Muslims, Jews, Hindus, and proponents of most other religions firmly believe that our
mortal lives are only a small part of our existence. What would show that they are right?
