Neoplatonism (also called “Platonism”) refers to the school of philosophical and religious thought, beginning with the philosopher Plotinus (b. 204–d. 270 ce), which is marked by certain metaphysical teachings on Plato and Aristotle. After Plotinus, the three major periods of Neoplatonism include: the writings of Plotinus’s student, Porphyry (b. 232–d. 305); Iamblichus and the school of Calchis (d. 326); and the 5th- and 6th-century schools of Athens and Alexandria, including Syrianus (d. 437), Proclus (b. 412–d. 485), Damascius (b. 458–d. 538), and Olympiodorus (b. c. 500–d. 570). Each of these three major movements also includes a great many other writers, particularly the last phase of late antique Neoplatonism, which was marked by a pronounced interest in commentaries on the works of Plato and Aristotle, with commentaries on the latter being particularly prevalent in 5th- and 6th-century Alexandria. Moreover, while “Neoplatonism” generally refers to the writings of pagans, the movement was heavily influential among Christian, Jewish, and Arabic thinkers, who adopted terminology and metaphysical principles well into the medieval period. As an extreme example of this, the Christian thinker Pseudo-Dionysius (fl. 500?) not only adopted much of Proclus’s language and thought, but parts of his treatises have been found to be a word for word copying of Proclus’s writing. Although Neoplatonism represents a wide group of authors, styles, and interests certain trends can be found throughout members of the philosophical movement; namely, Neoplatonists believe that the One is the principle of unification and source of all creation; all things emanate from the One and all things return to the One. Below the One is the level of Intellect, which houses the forms, followed by the Soul. One, Intellect, and Soul are all related to each other, with Intellect in some way emanating from the One, and returning to the One, and Soul, which emanates from and returns to Intellect. In Neoplatonic thought, the individual soul of man in some way returns to the One, by means of contemplation of the One and, for some authors, through sacramental practices known as theurgy. While Neoplatonists have these basic principles in common, authors vary in their understandings of the structure of the universe. Later authors, moreover, tend to introduce a greater number of intermediary entities. Because of the breadth of this subject matter, the bibliography will need to be limited to general works on Neoplatonism, works on particular topics, and works on only a handful of key authors who are considered to be key figures in the Athenian and Alexandrian schools of Neoplatonism: Plotinus, Porphyry, Iamblichus, Syrianus, Proclus, Pseudo-Dionysius, Damascius, and Olympiodorus.
