For Plotinus and Porphyry the emanations are as follows:
- To Hen (τό ἕν), The One: Deity without quality, sometimes called The Good.
- Nous (Νοῦς), Mind: The Universal consciousness, from which proceeds
- Psychē (Ψυχή), Soul: Including both individual and world soul, leading finally to
- Physis (Φύσις), Nature.
Neoplatonism
A school of thought influenced by the ideas of the philosopher Plato. Advocated by such figures as Plotinus, Porphyry, Iamblichus, and Proclus, Neoplatonism held that the human soul had fallen from its divine origins into the material world, but that it could progress, through a number of hierarchical spheres of being, to return to its divine origins once more.89 The later Neoplatonists performed theurgy, a ritual practice attested in such sources as the Chaldean Oracles. Scholars are still unsure of precisely what theurgy involved, but know it involved a practice designed to make gods appear, who could then raise the theurgist's mind to the reality of the divine.
In late neoplatonism, the spiritual universe is regarded as a series of emanations from the One. From the One emanated the Divine Mind (Nous) and in turn from the Divine Mind emanated the World Soul (Psyche). Neoplatonists insisted that the One is absolutely transcendent and in the emanations nothing of the higher was lost or transmitted to the lower, which remained unchanged by the lower emanations.
Plotinus urged contemplations for those who wished to perform theurgy, the goal of which was to reunite with the Divine (called henosis)
monism, the doctrine that all of reality can be derived from a single principle, "the One".
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.
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 but "is prior to all existents".
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'.
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.
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.
The Demiurge of Neoplatonism is the Nous (mind of God), and is one of the three ordering principles: Arche (Gr. 'beginning') – the source of all things, Logos (Gr. 'reason/cause') – the underlying order that is hidden beneath appearances, Harmonia (Gr. 'harmony') – numerical ratios in mathematics.
