It is commonplace to use the term dualist to describe Plotinus’ psychology, since he sharply distinguishes the soul from the body, and he locates cognition and consciousness exclusively in the soul. However, my analysis of Plotinus’ theory of consciousness shows that his theory of the relation between the soul and the body is sui generis. A more appropriate term to characterize his psychology is multi-layered. Plotinus’ theory shows that there is more to being a conscious, mental state than we find in ordinary introspection, and that there is more to being a conscious human being than we find in the operations of the natural world.
