6. In what sense do we use the name of unity, and how can we conceive of it? We shall have to insist that the One is a unity much more perfect than the point of the monad; for in these, abstracting (geometric) magnitude, and numerical plurality, we do indeed stop at that which is most minute, and we come to rest in something indivisible; but this existed already in a divisible being, in a subject other than itself, while the One is neither in a subject other than itself, nor in anything divisible. If it be indivisible, neither is it of the same kind as that which is most minute. On the contrary, it is that which is greatest, not by (geometric) magnitude, but by power; possessing no (geometric) magnitude, it is indivisible in its power; for the beings beneath it are indivisible in their powers, and not in their mass (since they are incorporeal). We must also insist that the One is infinite, not as would be a mass of a magnitude which could be examined serially, but by the incommensurability of its power. Even though you should conceive of it as of intelligence or divinity, it is still higher. When by thought you consider it as the most perfect unity, it is still higher. You try to form for yourself an idea of a divinity by rising to what in your intelligence is most unitary (and yet He is still simpler); for He dwells within Himself, and contains nothing that is contingent. THE ONE IS SELF-SUFFICIENT AND NEEDS NOTHING FOR ESTABLISHMENT. His sovereign unity may best be understood by His being self-sufficient; for the most perfect principle is necessarily that which best suffices Himself, and which least needs anything else. Now anything that is not one, but manifold, needs something else. Not being one, but being composed of multiple elements, its being demands unification; but as the One is already one, He does not even need Himself. So much the more, the being that is manifold needs as many things as it contains; for each of the contained things exists only by its union with the others, and not in itself, and finds that it needs the others. Therefore such a being needs others, both for the things it contains, as for their totality. If then there must be something that fully suffices itself, it must surely be the One, which alone needs nothing either relatively to Himself, or to the other things. It needs nothing either to exist, or to be happy, or to be composed. To begin with, as He is the cause of the other beings, He does not owe His existence to them. Further, how could He derive His happiness from outside Himself? Within Him, happiness is not something contingent, but is His very nature. Again, as He does not occupy any space, He does not need any foundation on which to be edified, as if He could not sustain Himself. All that needs compounding is inanimate; without support it is no more than a mass ready to fall. (Far from needing any support) the One is the foundation of the edification of all other things; by giving
