On Immortality and the Nature of the Soul

Chapter 8 addresses the following issues: what is the soul, and how is it related to the body; if the soul is part of the body, does it perish along with the destruction of the body, or does a part of the soul survive; if part of the soul is immortal, can it acquire new knowledge after death; is the body resurrected in the world to come, or is salvation purely spiritual; if salvation is spiritual, are rewards and punishments in the world to come spiritual as well, or are they material? Jewish philosophers discussed these issues against the backdrop of Platonic, Aristotelian, and Islamic thought.
