Iamblichus (245-325), successor to Plotinus and Porphyry, brought a new religiosity to Neoplatonism. His theory of the soul is at the heart of his philosophical system. For Iamblichus, the human soul is so far inferior to the divine that its salvation depends not on philosophy alone (as it did for Plotinus) but on the aid of the gods and other divinities. This edition of the fragments of Iamblichus' major work on the soul, De Anima, is accompanied by the first English translation of the work and a commentary which explains the philosophical background and Iamblichus' doctrine of the soul. Included too are excerpts from the Pseudo-Simplicius and Priscianus (also translated with commentary) that shed further light on Iamblichus' treatise.

Brill’s Companion to the Reception of Plato in Antiquity offers a comprehensive account of the ways in which ancient readers responded to Plato, as philosopher, as author, and more generally as a central figure in the intellectual heritage of Classical Greece, from his death in the fourth century BCE until the Platonist and Aristotelian commentators in the sixth century CE. The volume is divided into three sections: ‘Early Developments in Reception’ (four chapters); ‘Early Imperial Reception’ (nine chapters); and ‘Early Christianity and Late Antique Platonism’ (eighteen chapters). Sectional introductions cover matters of importance that could not easily be covered in dedicated chapters. The book demonstrates the great variety of approaches to and interpretations of Plato among even his most dedicated ancient readers, offering some salutary lessons for his modern readers too.

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.

The Neoplatonists have a perfectionist view of freedom: an entity is free to the extent that it succeeds in making itself good. Free entities are wholly in control of themselves—they are self-determining, self-constituting, and self-knowing. Neoplatonist philosophers argue that such freedom is only possible for non-bodily things. The human soul is free insofar as it rises above bodily things and engages in intellection, but when it turns its desires to bodily things, it is drawn under the sway of fate and becomes enslaved. Ursula Coope discusses this notion of freedom and its relation to questions about responsibility. She explains the important role of notions of self-reflexivity in Neoplatonist accounts of both freedom and responsibility. In Part I, Coope sets out the puzzles Neoplatonist philosophers face about freedom and responsibility and explains how these puzzles arise from earlier discussions. Part II explores the metaphysical underpinnings of the Neoplatonist notion of freedom (concentrating especially on the views of Plotinus and Proclus). In what sense, if any, is the ultimate first principle of everything (the One) free? If everything else is under this ultimate first principle, how can anything other than the One be free? What is the connection between freedom and nonbodiliness? Finally, Coope considers in Part III questions about responsibility, arising from this perfectionist view of freedom. Why are human beings responsible for their behaviour, in a way that other animals are not? If we are enslaved when we act viciously, how can we be to blame for our vicious actions and choices?

Does the soul have parts? What kind of parts? And how do all the parts make together a whole? Many ancient, medieval and early modern philosophers discussed these questions, thus providing a mereological analysis of the soul. The eleven chapters reconstruct and critically examine radically different theories. They make clear that the question of how a single soul can have an internal complexity was a crucial issue for many classical thinkers.

Neoplatonic Demons and Angels is a collection of eleven studies which examine, in chronological order, the place reserved for angels and demons not only by the main Neoplatonic philosophers (Plotinus, Porphyry, Iamblichus, and Proclus), but also in Gnosticism, the Chaldaean Oracles, Christian Neoplatonism, especially by Pseudo-Dionysius the Areopagite. This volume originates from a panel held at the 2014 ISNS meeting in Lisbon, but is supplemented by a number of invited papers.

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.

Attributed to Iamblichus (4th cent. AD), The Theology of Arithmetic is about the mystical, mathmatical and cosmological symbolism of the first ten numbers. Its is the longest work on number symbolism to survive from the ancient world, and Robin Waterfield's careful translation contains helpful footnotes, an extensive glossary, bibliography, and foreword by Keith Critchlow. Never before translated from ancient Greek, this important sourcework is indispensable for anyone intereted in Pythagorean though, Neoplatonism, or the symbolism of Numbers.
