What is Plotinus?
Plotinus (c. 204–270 CE) was a Greek philosopher who taught in Rome. He is the founder of Neoplatonism and the author of the [Enneads](lexicon:enneads), fifty-four treatises that set out the most fully developed non-dual metaphysics in the Western philosophical tradition. His central concept is the One: an absolute beyond being and thought, the source from which all reality flows by emanation, and the destination to which contemplative practice returns.
Life and the Enneads
Plotinus was born around 204 CE in Lykopolis (modern Asyut) in Roman Egypt. He studied philosophy in Alexandria for eleven years under Ammonius Saccas, who also taught the Christian theologian Origen. In 243 he joined the emperor Gordian III's eastern campaign, intending to reach Persia and India to study eastern philosophy. The expedition collapsed when Gordian was killed. Plotinus then settled in Rome in 244. His teaching circle met in the household of a Roman woman named Gemina and drew philosophers, physicians, and government officials. After Plotinus died in 270, his student Porphyry edited the fifty-four treatises, arranged them into six groups of nine, and wrote the only surviving biography of the master.
The teaching
The Enneads are built around three levels. Plotinus calls them hypostases. At the base is the One: absolutely simple, beyond being and thought, beyond any category. It is not a being among beings but the source from which beings derive existence. From the One flows Nous (Intellect), where thought and its objects are not yet separate. This is where Plato's Forms reside, and its activity is eternal self-contemplation. From Intellect flows Psychē (Soul), which produces the temporal, embodied world through its outward movement. The fourth term is henōsis, the return: the contemplative path back through Soul and Intellect to union with the One. Plotinus called this the flight of the alone to the alone. Porphyry records four occasions when Plotinus is said to have reached this union.
Influence
The Enneads reached later traditions through two main channels. The first was the pagan Neoplatonist school: Porphyry, Iamblichus, Proclus, and Damascius, whose commentaries transmitted the system to medieval Latin and Greek readers. The second was Christian theology. Augustine of Hippo names certain books of the Platonists in the Confessions as what first convinced him that the divine is not a body, almost certainly Plotinus in Latin translation. Pseudo-Dionysius the Areopagite then carried the apophatic method into Christian theology, shaping Meister Eckhart and the English fourteenth-century contemplative writers. In Islamic philosophy, the Theology of Aristotle, an Arabic paraphrase of the Enneads mistakenly attributed to Aristotle, gave al-Fārābī, al-Ghazālī, and Ibn ʿArabī the Neoplatonic framework behind the Sufi waḥdat al-wujūd doctrine.
Plotinus and adjacent traditions
Plotinus is often grouped with Plato, but his system goes beyond him. Plato's Forms are objects of contemplation; for Plotinus they sit within Intellect and are subordinate to the One, which has no real parallel in Plato's dialogues. Plotinus is also compared to Advaita Vedānta: the perennial-philosophy reading treats the One as the Western equivalent of Brahman. The comparison is real but limited. Advaita grounds itself in the Upaniṣads and Śaṅkara's commentaries; Plotinus works inside the Greek cosmological framework. Both traditions hold that the absolute is not a being among beings and that the path is recognition, not acquisition.
In the index
No item in the index is recorded directly under Plotinus. The Anglophone reception of the Enneads has stayed mostly inside academic philosophy rather than the contemplative-practice culture the corpus tracks. The contemporary teachers who carry the Plotinian insight use Vedāntic and direct-path vocabulary rather than Neoplatonic terms. Rupert Spira's *Being Aware of Being Aware* and Adyashanti's *Do Nothing* work from the same structural recognition: the absolute is not a thing, and the return to it is given rather than produced by technique. The standard English translations are the Stephen MacKenna edition (Penguin and Larson) and the A. H. Armstrong Loeb Classical Library bilingual edition.
