But in the fourteenth book of this work we have proved that, according to the Platonists' own theory, souls, even when purged from all pollution of the body, are yet possessed by a monstrous desire to return again into their bodies. But where desire can exist, certainly pain also can exist; for desire frustrated, either by missing what it aims at or losing what it had attained, is turned into pain. And therefore, if the soul, which is either the only or the chief sufferer, has yet a kind of immortality of its own, it is inconsequent to say that because the bodies of the damned shall suffer pain, therefore they shall die. In fine, if the body causes the soul to suffer, why can the body not cause death as well as suffering, unless because it does not follow that what causes pain causes death as well? And why then is it incredible that these fires can cause pain but not death to those bodies we speak of, just as the bodies themselves cause pain, but not therefore death, to the souls? Pain is therefore no necessary presumption of death.
