Introduction

After Plato and Aristotle, Plotinus (204/5–270 CE) stands out as the most accomplished and influential philosopher of Antiquity. He is also the only philosopher from this period, other than Plato, whose works are all extant. In his writings, collectively known by the name given to them by his student and editor, Porphyry, as Enneads (“nines” in Greek, for the six groups of nine “treatises”), he engages with the entire history of philosophy up to that time, systematizing Plato and defending that system against all comers, especially Peripatetics, Skeptics, and Stoics. For the next three hundred or so years, philosophy in Late Antiquity took Plotinus as its starting point. Proclus (412–485 CE) thought of him as the principal “exegete of the Platonic revelation.” Philosophy in Late Antiquity was essentially Platonism as constructed by Plotinus, and it is this philosophy that Christians, Muslims, and Jews appropriated and struggled to fit within their theological frameworks.

General Overviews

Although Plotinus tried to present Platonism as a system, his writings are anything but systematic. They are explicitly occasional pieces, responding to and summarizing seminar discussions held with a wide range of students. These writings do not present the elements of his philosophy in the neat divisions typically used today. Because Plotinus held that the solution to any genuine philosophical problem must ultimately adduce his three fundamental “hypostases”— the One, Intellect, and Soul—someone first encountering Plotinus should begin with a general introduction that gives prominence to the nature of these three principles and the way they operate together. Against this background, much, but, alas, by no means all, of his writings becomes intelligible. Dillon 1988 and Henry 1991 provide helpful overviews of Plotinus’s philosophy. O’Meara 1993 is a solid monograph-length introduction to the main lines of Plotinus’s thought. Rist 1967 is a seminal study. Halfwassen 2004 situates Plotinus within his predecessors and successors. Gerson 1994 is a more analytical oriented, comprehensive study. Hadot 1963 is a deeply conceived reflection on the principles of Plotinus’s philosophy. Lloyd 1990 and Wallis 1995 locate Plotinus with the larger picture of late Greek philosophy.
