The six groups of nine treatises constituting the philosophical works of the 3rd-century Greek philosopher Plotinus, edited and arranged after his death by his student Porphyry. The treatises develop a metaphysics in which all reality unfolds from a transcendent "One" through the descending hypostases of Intellect (Nous) and Soul, and in which the individual soul can return to its source through contemplative ascent. This Penguin Classics volume is an abridged selection from Stephen MacKenna's English translation, with introductions and notes by John Dillon.
Never did eye see the sun unless it had first become sunlike, and never can the soul have vision of the First Beauty unless itself be beautiful.
Ennead I.6.9, "On Beauty"
First lines
Pleasure and distress, fear and courage, desire and aversion, where have these affections and experiences their seat? Clearly, either in the Soul alone, or in the Soul as employing the body, or in some third entity deriving from both.

Reception
The Enneads is the foundational text of Neoplatonism and the most influential pagan late-antique philosophical work on subsequent Christian, Islamic, and Jewish mysticism — Augustine, Pseudo-Dionysius, al-Farabi, Avicenna, Ibn ʿArabi, and Maimonides all engaged with it directly. Modern scholarship (Pierre Hadot's Plotinus, or the Simplicity of Vision, A. H. Armstrong's Loeb edition, Lloyd Gerson's analytic reconstruction) has reframed Plotinus as a systematic philosopher rather than merely a mystic; Stephen MacKenna's 1917–1930 English translation, though sometimes loose, remains the most widely-read version. The Penguin Classics edition is an abridged selection from MacKenna with introductions by John Dillon.
Frequently asked
What are the Enneads?
The Enneads are the collected philosophical treatises of Plotinus, written between roughly 253 and 270 CE and organised after his death by his student Porphyry into six groups of nine tractates. They are the foundational text of Neoplatonism and constitute the last major systematic work of ancient Greek philosophy. The Penguin Classics edition is an abridged selection in Stephen MacKenna's English translation, with introductions by John Dillon.
What does Plotinus mean by "the One"?
In Plotinus's metaphysics, the One is the absolutely simple, transcendent source from which all reality emanates. It is beyond thought and being — the One cannot be defined, since all definition implies multiplicity. From the One emanates Intellect (Nous), from Intellect emanates Soul, and from Soul proceeds the material world. The individual soul's goal is to ascend back through these levels to the One through contemplative practice.
How did the Enneads influence later religious and philosophical thought?
The Enneads shaped Christian, Islamic, and Jewish mysticism in ways still traceable. Augustine read Plotinus before his conversion; Pseudo-Dionysius built his apophatic theology on Neoplatonic foundations; al-Farabi and Avicenna absorbed the emanation scheme; Maimonides drew on Neoplatonist negative theology. In the Renaissance, Marsilio Ficino's Latin translation made the Enneads central to European philosophy again. The Enneads are considered the most influential pagan philosophical text of late antiquity.
