The present paper is intended primarily for classicists who are not specialists in Neoplatonism and will therefore tell experts in Plotinus little of which they are not already well aware. Its purpose is to explain Plotinus' views on a subject which finds itself, perhaps surprisingly, once again of some contemporary interest, and where misunderstandings and emotionally toned judgments are only too easy. It will be concerned as much with the reasons underlying Plotinus' beliefs as with those beliefs themselves, and in particular will show how his views on paranormal phenomena spring naturally from some of the most fundamental principles of his whole philosophy.
