The final chapter is on the question of immaterial mind, the ghost in the
machine. Some time is spent on Cartesian dualism, partly because Descartes is often
misquoted and misunderstood, but all the main views are examined, without reaching a
definite conclusion. I believe we do not know, we only have beliefs about this, and our
beliefs depend on where our faith lies. The book ends by giving some of the
implications that I believe follow from this uncertainty.
