Plotin interprète de la chôra du Timée (Ennéades III, 6 [26], 13‑18)

Abstract

How does Plotinus interpret the chora in Plato’s Timaeus ? For him, Timaeus 48e‑52d deals with matter (hyle). The identification of chora with hyle goes back to Aristotle’s Physics IV.2. Aristotle’s interpretation of Plato’s chora as matter was echoed by Theophrastus and the Stoics and prevailed in Middle‑Platonist, neo‑Pythagorean and early Christian authors. In addition to the identification of chora with hyle, the ancient interpreters of the Timaeus conflated hyle with Plato’s ananke (Tim. 47e‑48a). Plato himself distinguishes between chora and ananke. The latter denotes everything that appears in the “receptacle” prior to the ordering of the world by the demiurge, while chora is another name for the receptacle itself. In Plato, the receptacle accounts for the fact both that there are transient images of intelligible beings and that these images appear to occupy a place, i.e. that they are spatially extended. This is why the receptacle is given its alternative name “ground” (chora) and why it is also called “place” (topos) and “seat” (hedra). Although the receptacle itself cannot be spatially extended in the same way as that which appears “in it”, it is the cause of spatial extension. For Plotinus, two characteristics of matter are of primary importance : lack of size and impassibility. In the treatise II .4.[12].2‑5, he highlights the former, and in III .6[26].7‑19 he elaborates on the latter, while commenting once again on the former. In III .6[26].7‑19, he argues that this conception of matter is in line with how Plato conceives of it in the Timaeus. The “receptacle” cannot be acted upon (paschein) nor can it possess any size (megethos). Only the images of true beings “in” it can. In doing so, however, they make matter appear to “stretch out” alongside themselves. But this is not actually the case, because matter itself has no extension. On one point, however, Plotinus’ account differs from Plato’s. According to Plotinus, not only does matter not possess size, but it is not the cause of size either. The size of the appearances derives from the formulas (logoi) of which these appearances are images. Each formula encompasses within itself the measure of the size that its image will assume : the formula of horse encompasses the size of a particular horse, the formula of human being the size of a particular human being. Plotinus describes in more detail how a formula, in unfolding out of the soul, “stretches out”, thus acquiring size. He also makes a comparison between this process and the way in which formulas in the human soul display images of themselves in our image‑making faculty. He characterises this process as a motion starting from the formula and resulting in its “division” (merismos). This is what makes the image of the formula extended, i.e. divided partes extra partes, when it appears against the invisible background of matter. Since matter neither possesses size nor is the cause of it, it can be called “ground” (chora), “place” (topos) or “seat” (hedra) only in an improper way.
