THE SUPREME IS ONE ONLY IN A FIGURATIVE SENSE.

The principle that is superior to what is highest among beings, to

Intelligence (or intellect, or intelligible world) (may well be sought

after). There must indeed be some principle above Intelligence; for

intelligence does indeed aspire to become one, but it is not one,

possessing only the form of unity. Considered in itself, Intelligence

is not divided, but is genuinely present to itself. It does not

dismember itself because it is next to the One, though it dared to

withdraw therefrom. What is above Intelligence is Unity itself, an

incomprehensible miracle, of which it cannot even be said that it

is essence, lest we make of it the attribute of something else, and

to whom no name is really suitable. If however He must be named, we

may indeed call Him in general Unity, but only on the preliminary

understanding that He was not first something else, and then only

later became unity. That is why the One is so difficult to understand

in Himself; He is rather known by His offspring; that is, by Being,

because Intelligence leads up to Being. The nature of the One, indeed,

is the source of excellent things, the power which begets beings, while

remaining within Himself, without undergoing any diminution, without

passing into the beings to which He gives birth.[196] If we call this

principle Unity, it is only for the mutual convenience of rising to

some indivisible conception, and in unifying our soul. But when we say

that this principle is one and indivisible, it is not in the same sense

that we say it of the (geometric) point, and of the (arithmetical unity

called the) monad. What is one in the sense of the unity of the point

or the monad, is a principle of quantity, and would not exist unless

preceded by being and the principle which precedes even that being. It

is not of this kind of unity that we must think; still we believe that

the point and the monad have analogy with the One by their simplicity

as well as by the absence of all manifoldness and of all division.
