Enneads VI.2: The Categories of Plotinos
By Tending Towards the One, Everything Tends Towards the Good
12. We therefore assert (that by moving towards unity everything moves towards the Good). How can it be, however, that Goodness should consist in coming closer to unity, even for number, which is inanimate? This question might as well be asked about any inanimate object whatever. If we were told that such (beings) do not enjoy (existence), we might answer that we are here treating of beings according to their proximity to unity only. If, for instance, we were asked how a point can participate in the Good, we might answer by a retort, asking whether we are dealing with the Point in itself. Then we would answer by the observation that the state of affairs was the same for all things of the same kind. If however we were pressed about the point considered as existing in some object, as, for instance, in the circle, we would answer that for such a point, the Good is the good of the circle (of which it forms part); that such is the Good towards which it aspires, and that it seeks that as far as possible through the intermediation of the circle.
