Abstract

In the dissertation I explore three central issues in Plotinus' philosophical psychology: The fall of the soul, the relationships of soul and body, and the concept of the ego. ;Chapter 1 introduces the issues. Chapter 2 argues for a dual-aspect theory about the soul's fall. Chapter 3 characterizes the relationships between soul and body. Much of the chapter is devoted to distancing Plotinus' dualism from Cartesian dualism. The chapter ends with a discussion of Plotinus on perception. Chapter 4 investigates the concept of the ego, the function of the ego in union with the One, and the relationship between the ego and the other powers of the soul
