Is the expression of the essence of something simultaneously the expression of its unity, so that it possesses as much unity as it possesses essence? Or does this simultaneousness exist without any direct proportion between the amount of unity and essence? Yes; for it is possible that something have less unity without, on that account, having any the less essence; an army, a choric ballet have not less essence than a house, though far less unity. The unity present in each thing seems therefore to aspire to the Good, which has the most unity;[311] for the closer something approaches the Good, the greater unity does it achieve; that is the criterion of greater or less unity. Indeed, every (being) desires not only merely to be (alive), but to enjoy the Good. That is why everything, so far as it can, hastens to become one, and those (beings) which by nature possess unity naturally trend towards Him by desiring to unite with themselves. For every (being) hastens not to separate from others, but on the contrary their tendency is to tend towards each other and themselves. That is why all souls, while preserving their individual nature, would like to fuse into a single soul. The One reigns everywhere in the sense-world, as well as in the Intelligible. It is from Him that everything originates, it is towards Him that everything trends. In Him do all (beings) seek their principle and their goal; for only therein do they find their good; only by that does each (being) subsist, and occupies its place in the universe; once that it exists, no (being) could help trending towards the One. This occurs not only in nature, but even in the arts; where each art seeks, to the extent of its ability, to conform its works to unity, to the extent of its ability, and to the possibilities of its works. But that which succeeds best, is Essence itself, which is quite close to unity. FURTHER REASONS WHY UNITY IS NOT A CATEGORY.
