Neoplatonism started with
Plotinus in the 3rd century AD. Three distinct phases in classical Neoplatonism after Plotinus can be distinguished: the work of his student
Porphyry; that of
Iamblichus and his school in Syria; and the period in the 5th and 6th centuries, when the Academies in
Alexandria and
Athens flourished. Porphyry, in
On the One School of Plato and Aristotle, stated that Ammonius' view was that the philosophies of Plato and Aristotle were in harmony. Both Christians (see
Eusebius,
Jerome, and
Origen) and pagans (see Porphyry and Plotinus) claimed him as a teacher, and to be an adherent of their preferred faith: Eusebius and Jerome wrote that Ammonius was a Christian until his death, whereas Porphyry asserted that he had renounced Christianity and embraced pagan philosophy.

Plotinus ( – 270) is widely considered the father of Neoplatonism. Much of our biographical information about him comes from Porphyry's preface to his edition of Plotinus'
Enneads. While he was himself influenced by the teachings of classical
Greek,
Persian, and
Indian philosophy and
Egyptian theology, his metaphysical writings later inspired numerous
Pagan,
Jewish,
Christian,
Gnostic, and
Islamic metaphysicians and
mystics over the centuries. Plotinus taught that there is a supreme, totally transcendent "One", containing no division, multiplicity, nor distinction; likewise, it is beyond all categories of being and non-being. The concept of "being" is derived by us from the objects of human experience and is an attribute of such objects, but the infinite, transcendent One is beyond all such objects and, therefore, is beyond the concepts which we can derive from them. The One "cannot be any existing thing" and cannot be merely the sum of all such things (compare the Stoic doctrine of disbelief in non-material existence) but "is prior to all existents".
Porphyry Porphyry () wrote widely on astrology, religion, philosophy, and musical theory. He produced a biography of his teacher, Plotinus. He is important in the history of mathematics because of his commentary on ''
Euclid's Elements, which Pappus used when he wrote his own commentary. Porphyry is also known as an opponent of Christianity and as a defender of paganism; of his Adversus Christianos
(Against the Christians'') in 15 books, only fragments remain. He famously said, "The gods have proclaimed Christ to have been most pious, but the Christians are a confused and vicious sect."
Iamblichus Iamblichus () influenced the direction taken by later Neoplatonic philosophy. He is perhaps best known for the compendium
The Life of Pythagoras, his commentary on Pythagorean philosophy, and his
De Mysteriis. In Iamblichus' system, the realm of divinities stretched from the original One down to material nature itself, where soul, in fact, descended into matter and became "embodied" as human beings. The world is thus peopled by a crowd of superhuman beings influencing natural events and possessing and communicating knowledge of the future, and who are all accessible to prayers and offerings. Iamblichus had salvation as his final goal (see
henosis). The embodied soul was to return to divinity by performing certain rites, or
theurgy, literally, 'divine-working'.
Academies After Plotinus () and his student Porphyry (), Aristotle's (non-biological) works entered the
curriculum of Platonic thought. Porphyry's introduction (
Isagoge) to Aristotle's
Categoria was important as an introduction to
logic, and the study of Aristotle became an introduction to the study of Plato in the late Platonism of
Athens and
Alexandria. The commentaries of this group seek to harmonise Plato, Aristotle, and—often—the
Stoics. Some Neoplatonic works were attributed directly to Plato or Aristotle.
De Mundo, for instance, is thought to be the work of a '
pseudo-Aristotle' though this remains debatable.
Hypatia Hypatia ( – 415) was a Greek philosopher and mathematician who served as head of the Platonist school in Alexandria, Egypt, where she taught philosophy, mathematics and astronomy. She was murdered in a church by a fanatical mob of
Coptic Parabalani monks because she had been advising the prefect of Egypt
Orestes during his feud with
Cyril, Alexandria's dynastic archbishop. The extent of Cyril's personal involvement in her murder remains a matter of scholarly debate.
Proclus Proclus Lycaeus (February 8, 412 – April 17, 485) was a Greek Neoplatonist, and one of the last major Greek philosophers (see
Damascius). He set forth one of the most elaborate, complex, and fully developed Neoplatonic systems, providing also an allegorical way of reading the dialogues of Plato. The particular characteristic of Proclus' system is his insertion of a level of individual ones, called
henads, between the One itself and the divine Intellect, which is the second principle. The
henads are beyond being, like the One itself, but they stand at the head of chains of causation (
seirai or
taxeis) and in some manner give to these chains their particular character. They are also identified with the traditional Greek gods, so one
henad might be
Apollo and be the cause of all things Apollonian, while another might be
Helios and be the cause of all sunny things. The
henads serve both to protect the One itself from any hint of multiplicity and to draw up the rest of the universe towards the One, by being a connecting, intermediate stage between absolute unity and determinate multiplicity. In the Middle Ages most Plotinus' insights will be presented as authored by Proclus. ==Ideas== The
Enneads of Plotinus are the primary and classical document of Neoplatonism. A
mystical work, it contains both theoretical and practical sections; the theoretical parts deal with the high origin of the human
soul, showing how it has departed from its first estate, while the practical parts show the way by which the soul may again return to the Eternal and Supreme. and the
teleological end of all existing things. Although properly speaking, there is no name appropriate for the first principle, the most adequate names are "the One" or "the Good". The One is so simple that it cannot even be said to exist or to be a being. Rather, the creative principle of all things is
beyond being, a notion which is derived from Book VI of the
Republic, when, in the course of his famous
analogy of the Sun, Plato says that the Good is beyond being () in power and dignity. In Plotinus' model of reality, the One is the cause of the rest of reality, which takes the form of two subsequent "
hypostases" or substances:
Nous and Soul (
psyché). Although Neoplatonists after Plotinus adhered to his cosmological scheme in its most general outline, later developments in the tradition also departed substantively from Plotinus' teachings regarding significant philosophical issues, such as the nature of evil.
Emanations From the One
emanated different levels of lesser realities known as "hypostases". At the highest level of reality exists "the One", from which emanates the
Nous or the mind. It is the first principle after the One and contains all knowledge in a unified form. It is both the knower, the known, and the act of knowing, embodying a complete unity. The Platonic realm of the Forms is contained within the Nous and acts as the archetype of the sensible world. From the Nous emanates a lesser reality known as the Soul, which receives information from the Nous and actualizes it. This act of "actualization" is the same as the creation of the sensible world, the realm of multiplicity, time, and space. This sensible realm is an imperfect copy of the
Nous and the Platonic realm of the Forms. The process of Emanation is beyond temporality as time does not exist in the One, the
Nous, or the Soul, but only in the sensible world. Despite their distinctions, these four realities are all part of the same unified reality unfolding within the One.
Demiurge or nous The original Being initially emanates, or throws out, the
nous (), which is a perfect image of the One and the archetype of all existing things. It is simultaneously both being and thought, idea and ideal world. As image, the
nous corresponds perfectly to the One, but as derivative, it is entirely different. What Plotinus understands by the
nous is the highest sphere accessible to the human mind, Evil here is understood as a parasite, having no-existence of its own (parahypostasis), an unavoidable outcome of the Universe, having an "other" necessity, as a harmonizing factor.
Celestial hierarchy is depicted raising his hand in an almost Christlike gesture. It has been suggested this conforms a strong Neoplatonic tradition in
Apamea at the time. Later Neoplatonic philosophers, especially Iamblichus, added hundreds of intermediate beings, such as
gods,
angels,
demons, and others, serving as mediators between the One and humanity. The Neoplatonist gods are omni-perfect beings and do not display the usual amoral behavior associated with their representations in the myths. • The One: God, The Good. Transcendent and ineffable. • The Hypercosmic Gods: those that make Essence, Life, and Soul • The
Demiurge: the Creator • The Cosmic Gods: those who make Being, Nature, and Matter—including the gods known to us from classical religion.
Evil Neoplatonists did not believe in an independent existence of
evil. They compared it to darkness, which does not exist in itself but only as the absence of light. So, too, evil is simply the absence of good. Things are good insofar as they exist; they are evil only insofar as they are imperfect, lacking some good which they should have.
Return to the One Neoplatonists believed human perfection and happiness were attainable in this world, without awaiting an
afterlife. Perfection and happiness—seen as synonymous—could be achieved through philosophical
contemplation. All people return to the One, from which they emanated. The Neoplatonists believed in the pre-existence and
immortality of the soul. The human soul consists of a lower irrational soul and a higher rational soul (
mind), both of which can be regarded as different powers of the one soul. It was widely held that the soul possesses a "vehicle" (), accounting for the human soul's immortality and allowing for its return to the One after death. After bodily death, the soul takes up a level in the
afterlife corresponding with the level at which it lived during its earthly life. The Neoplatonists believed in the principle of
reincarnation. Although the most pure and holy souls would dwell in the highest regions, the impure soul would undergo a purification, to be reincarnated into a new body, perhaps into animal form. Plotinus believed that a soul may be reincarnated into another human or even a different sort of animal. However, Porphyry maintained that human souls were reincarnated only into other humans. A soul which has returned to the One achieves union with the cosmic universal soul and does not descend again; at least, not in this world period. ==Influence==
