the injured soul should co-operate with the wrong-doer, or that a man should be able to change an incorporeal power into another substance. For if in bodies this were impossible, and one could not make a man’s body become that of an ass; much more were this impossible in the invisible soul; neither could one transform it into the substance of an evil spirit. So that these are the sayings of besotted old wives, and spectres to frighten children.
