There are many correspondences between Freudian metapsychology and Plotinian metaphysics. Many of Freud’s ideas seem to be rooted in classical philosophy, although acknowledgement is rarely given. Plotinus is a fruitful source for understanding how the mind works. For Freud, unconscious words become conscious images, and unconscious images become conscious words, but these processes do not happen independently of each other. They are wrapped up in a dialectical process that is better understood by reading Plotinus.
