The One
In one line Plotinus traced all things back to one source that gives without being used up.
Plotinus was born in Egypt around 204 CE, studied in Alexandria and taught in Rome. His student Porphyry gathered his essays into six sets of nine, the Enneads. Plotinus saw himself as a reader of Plato, but he built a new picture of reality, later called Neoplatonism.
At the top is the One, perfectly simple and beyond any description. From it comes Intellect, the realm of the Forms, and from Intellect comes Soul, which gives life to the world. Each level flows from the one above the way light streams from the sun, and the source loses nothing by giving.
The way back is inward. By turning attention from scattered things toward what unifies them, a person climbs back toward the source.
Go deeper
Porphyry reports that Plotinus reached union with the One four times while Porphyry was with him, and that he seemed ashamed of being in a body. His picture shaped thinkers far beyond Rome. Augustine read “the books of the Platonists” before his conversion, and an Arabic paraphrase of parts of the Enneads, circulating as the Theology of Aristotle, influenced Islamic philosophers.
The cluttered week
Ana’s week is a pile of errands, meetings and messages, and she feels pulled in twenty directions. Each task seems to be its own small emergency.
She asks what they are all for. Most serve two aims: keeping her small bakery running and caring for her father. With that unity in view, the tasks line up behind it, and a few that serve neither fall away.
Try this today Pick a scattered part of your life, such as this week’s tasks, and name the one aim they all serve.
