Fourth Century

- ca. 390 - Nemesius wrote De Natura Hominis (On Human Nature); large sections were incorporated in Saint John Damascene's De Fide Orthodoxia in the eighth century. Nemesius' book De Placitis Hippocratis et Platonis (On the Doctrines of Hippocrates and Plato) contains many passages concerning Galen's anatomy and physiology, believing that different cavities of the brain were responsible for different functions.
- 397-398 – St. Augustine of Hippo published Confessions, which anticipated Freud by near-discovery of the subconscious. Augustine's most complete account of the soul is in De Quantitate Animae (The Greatness of the Soul). The work assumes a Platonic model of the soul.
