How did Plotinus conceive of the relation existing between the human soul and the human body? Plato did not give the impression of being vitally concerned about this question. Although Plotinus professes to be a follower of Plato, he is much more profoundly influenced in this instance by Aristotle. Besides owing much to Aristotle, Plotinus' account of sensation, pleasure and pain, and the emotions in general clearly shows the influence of the medical theories of Galen.
Plotinus' belief in reincarnation shows the more Platonic strain in his approach to the body-soul problem.
