Drawing on recent scholarship and delving systematically into Iamblichean texts, these ten papers establish Iamblichus as the great innovator of Neoplatonic philosophy who broadened its appeal for future generations of philosophers.

Plotinus on Number studies the fundamental role which number plays in the architecture of the universe in Neoplatonic philosophy. This book draws attention to Platinus' concept as a necesscary and fundamental link between the Platonic and the late Neoplatonic theories of number.

For the first time, the reader can have a synoptic view of the reception of Pythagoras and Pythagoreanism in the Middle Ages and the Renaissance, East and West, in a multicultural perspective. All the major themes of Pythagoreanism are addressed, from mathematics, number philosophy and metaphysics to ethics and religious thought.

Either as insider or as sensitive observer, Plutarch provides us with exceptional evidence to reconstruct the spiritual and intellectual atmosphere of the first centuries CE. This collection of articles sheds important light on the religious and philosophical discourse of Late Antiquity.

Was Plato a Platonist? While ancient disciples of Plato would have answered this question in the affirmative, modern scholars have generally denied that Plato’s own philosophy was in substantial agreement with that of the Platonists of succeeding centuries. In From Plato to Platonism, Lloyd P. Gerson argues that the ancients were correct in their assessment. He arrives at this conclusion in an especially ingenious manner, challenging fundamental assumptions about how Plato’s teachings have come to be understood. Through deft readings of the philosophical principles found in Plato's dialogues and in the Platonic tradition beginning with Aristotle, he shows that Platonism, broadly conceived, is the polar opposite of naturalism and that the history of philosophy from Plato until the seventeenth century was the history of various efforts to find the most consistent and complete version of "anti-naturalism."Gerson contends that the philosophical position of Plato—Plato’s own Platonism, so to speak—was produced out of a matrix he calls "Ur-Platonism." According to Gerson, Ur-Platonism is the conjunction of five "antis" that in total arrive at anti-naturalism: anti-nominalism, anti-mechanism, anti-materialism, anti-relativism, and anti-skepticism. Plato’s Platonism is an attempt to construct the most consistent and defensible positive system uniting the five "antis." It is also the system that all later Platonists throughout Antiquity attributed to Plato when countering attacks from critics including Peripatetics, Stoics, and Sceptics. In conclusion, Gerson shows that Late Antique philosophers such as Proclus were right in regarding Plotinus as "the great exegete of the Platonic revelation."

Iamblichus was once considered one of the great philosophers. The Emperor Julian followed Iamblichus's teachings to guide the restoration of traditional pagan cults in his campaign against Christianity. Although Julian was unsuccessful, Iamblichus's ideas persisted well into the Middle Ages and beyond. His vision of a hierarchical cosmos united by divine ritual became the dominant worldview for the entire medieval world. Even Ralph Waldo Emerson wrote that he expected a reading of Iamblichus to cause a "revival in the churches." But modern scholars have dismissed him, seeing theurgy as ritual magic or "manipulation of the gods." Shaw, however, shows that theurgy was a subtle and intellectually sophisticated attempt to apply Platonic and Pythagorean teachings to the full expression of human existence in the material world.

This is a major reinterpretation of ancient philosophy that recovers the long Greek and Roman tradition of philosophy as a complete way of life--and not simply an intellectual discipline. Distinguished philosopher John Cooper traces how, for many ancient thinkers, philosophy was not just to be studied or even used to solve particular practical problems. Rather, philosophy--not just ethics but even logic and physical theory--was literally to be lived. Yet there was great disagreement about how to live philosophically: philosophy was not one but many, mutually opposed, ways of life. Examining this tradition from its establishment by Socrates in the fifth century BCE through Plotinus in the third century CE and the eclipse of pagan philosophy by Christianity, Pursuits of Wisdom examines six central philosophies of living--Socratic, Aristotelian, Stoic, Epicurean, Skeptic, and the Platonist life of late antiquity. The book describes the shared assumptions that allowed these thinkers to conceive of their philosophies as ways of life, as well as the distinctive ideas that led them to widely different conclusions about the best human life. Clearing up many common misperceptions and simplifications, Cooper explains in detail the Socratic devotion to philosophical discussion about human nature, human life, and human good; the Aristotelian focus on the true place of humans within the total system of the natural world; the Stoic commitment to dutifully accepting Zeus's plans; the Epicurean pursuit of pleasure through tranquil activities that exercise perception, thought, and feeling; the Skeptical eschewal of all critical reasoning in forming their beliefs; and, finally, the late Platonist emphasis on spiritual concerns and the eternal realm of Being. Pursuits of Wisdom is essential reading for anyone interested in understanding what the great philosophers of antiquity thought was the true purpose of philosophy--and of life.

Many philosophers in the ancient world shared a unitary vision of philosophy – meaning 'love of wisdom' – not just as a theoretical discipline, but as a way of life. Specifically, for the late Neoplatonic thinkers, philosophy began with self-knowledge, which led to a person's inner conversion or transformation into a lover, a human being erotically striving toward the totality of the real. This metamorphosis amounted to a complete existential conversion. It was initiated by learned guides who cultivated higher and higher levels of virtue in their students, leading, in the end, to their vision of the Good, or the One. In this book, James M. Ambury closely analyses two central texts in this tradition: the commentaries by Proclus (412–485 AD) and Olympiodorus (495–560 AD) on the Platonic Alcibiades I. Ambury's powerful study illuminates the way philosophy was conceived during a crucial period of its history, in the lecture halls of late antiquity.
