Plotinus

Enneads

Ἐννεάδες

Plotinus (AD 204/5–270) was born in Egypt, studied philosophy in Alexandria for eleven years under the obscure teacher Ammonius, and in 244 settled in Rome, where he taught a circle of senators, doctors and friends until his death. He began writing only at about fifty, in short treatises that grew out of the questions raised in his seminars. After his death his pupil Porphyry edited them, cutting and grouping them into six sets of nine—in Greek, “enneads”—arranged to lead the reader upward: from ethics and the human being (I) through the natural world (II–III) and the soul (IV) to Intellect, being and the One (V–VI).

Plotinus thought of himself as an interpreter of Plato, but he built something new: a picture of all reality flowing from a single source, the One or the Good, which is beyond being and beyond thought. From it comes Intellect, the realm of the Forms, where thinking and what is thought are one; from Intellect comes Soul, which orders and animates the visible cosmos; at the bottom is matter, formless and closest to nothing. The movement runs both ways: everything proceeds from the One and everything longs to return to it, and the human soul, never wholly descended, can turn inward and rise through virtue and philosophy to Intellect and at last to union with the One.

The treatises are dense, conversational and full of objections raised and answered, and Plotinus writes with unusual force when he describes the ascent: the soul sculpting its own statue (I.6), the vision of intelligible beauty (V.8), the call to “cut away everything” (V.3), and the “flight of the alone to the alone” that ends the last treatise (VI.9). Through Porphyry, Augustine, Pseudo-Dionysius, the Arabic “Theology of Aristotle” and Ficino’s Latin translation, the Enneads shaped Christian, Muslim and Jewish mysticism and Renaissance thought.

About Plotinus

Plotinus (AD 204/5–270) was a Greek-speaking philosopher from Egypt who taught in Rome; his pupil Porphyry edited his treatises as the Enneads. He founded what is now called Neoplatonism, which shaped late ancient, Christian, Islamic and Renaissance thought.

Who’s who

Plato: The Athenian philosopher ("he" in "he says") whom Plotinus treats as his authority and constantly quotes and interprets.
Aristotle: Plato's student, whose categories and account of mind Plotinus examines and often criticizes.
Socrates: Plato's teacher, used mostly as the standard example of an individual person.
the Pythagoreans: Pythagoras and his followers, cited as ancient forerunners who hinted at the soul's descent and spoke of numbers.
Parmenides: Early Greek philosopher who held that being is one; Plotinus reads him as glimpsing Intellect.
Heraclitus: Early Greek philosopher of flux, cited on the soul's descent and as knowing the One as eternal.
Empedocles: Early Greek philosopher cited for his Love and Strife and for the soul's exile from the divine.
Anaxagoras: Early Greek philosopher of mind and mixture, cited on Intellect as pure and on matter as a mixture.
Ouranos, Kronos and Zeus: Three generations of gods read as images of the One, Intellect and Soul.
Aphrodite: The goddess of love, read as Soul; the heavenly Aphrodite as soul turned toward Intellect.
Poros and Penia: Resource and Poverty, the parents of Love in Plato's Symposium, interpreted in III.5.
Heracles: The hero whose shade is in Hades while he himself is among the gods, an image of the soul's two parts.
Odysseus: Homer's hero, leaving Circe and Calypso for his homeland, an image of the soul's return.
Prometheus: The Titan of the myth of Pandora, read as an image of providence shaping the world.

Key terms

the One τὸ ἕν to hen: The first principle and source of all things: utterly simple, beyond being and beyond thought, so that anything said of it is said only "as it were."
the Good τἀγαθόν tagathon: Another name for the One, seen as what everything desires and turns toward; it gives goodness to all things without needing anything itself.
Intellect νοῦς nous: The second level of reality, coming from the One: a divine mind in which thinking and what is thought are one, containing all the Forms.
intelligible νοητός noētos: Grasped by thought rather than by the senses; the intelligible world is the realm of Intellect and the Forms, the true original of the visible cosmos.
Soul of the All ἡ τοῦ παντὸς ψυχή hē tou pantos psychē: The third level of reality, also called the World Soul: it comes from Intellect, orders and animates the whole visible cosmos, and is akin to individual souls.
hypostasis ὑπόστασις hypostasis: A level of reality, literally "what stands under"; the three primary hypostases are the One, Intellect and Soul.
matter ὕλη hylē: The formless substrate at the bottom of reality, receiving form without being changed by it; closest to nothing, it is identified with privation and evil.
evil τὸ κακόν to kakon: Not a power in its own right but a lack of good; Plotinus locates its principle in matter, the absence of all form and measure.
rational principle λόγος logos: The formative principle by which soul and nature shape things, carrying the pattern of the Forms down into matter (seminal rational principles in living things).
Form εἶδος / ἰδέα eidos / idea: The intelligible patterns of things, which exist in Intellect; their images in matter are the forms of visible things.
activity ἐνέργεια energeia: A thing's being at work; each level of reality has an inner activity that is its own being and an outer activity that produces the next level.
contemplation θεωρία theōria: Seeing or beholding with the mind; Plotinus argues that all things, even nature, aspire to contemplation and that making is a byproduct of it.
virtue ἀρετή aretē: The same word as Aristotle's "excellence"; for Plotinus the civic virtues and, above them, the purifications by which the soul becomes like god.
purification κάθαρσις katharsis: The soul's freeing itself from the body and its passions so that it can turn back toward Intellect and the One.
beauty κάλλος / τὸ καλόν kallos / to kalon: The shining of form through things; bodily beauty points to beauty in souls and in Intellect, and beyond that to the Good.
eternity αἰών aiōn: The life of Intellect, whole and present all at once with no past or future; time is the life of Soul moving from one thing to the next.
