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.

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?

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.
