1. There is a principle having intellection of the external and another having self-intellection and thus further removed from duality.
Even the first mentioned is not without an effort towards the pure unity of which it is not so capable: it does actually contain its object, though as something other than itself.
In the self-intellective, there is not even this distinction of being: self-conversing, the subject is its own object, and thus takes the double form while remaining essentially a unity. The intellection is the more profound for this internal possession of the object.
This principle is the primally intellective since there can be no intellection without duality in unity. If there is no unity, perceiving principle and perceived object will be different, and the intellection, therefore, not primal: a principle concerned with something external cannot be the primally intellective since it does not possess the object as integrally its own or as itself; if it does possess the object as itself- the condition of true intellection- the two are one. Thus [in order to primal intellection] there must be a unity in duality, while a pure unity with no counterbalancing duality can have no object for its intellection and ceases to be intellective: in other words the primally intellective must be at once simplex and something else.
But the surest way of realizing that its nature demands this combination of unity and duality is to proceed upwards from the Soul, where the distinction can be made more dearly since the duality is exhibited more obviously.
We can imagine the Soul as a double light, a lesser corresponding to the soul proper, a purer representing its intellective phase; if now we suppose this intellective light equal to the light which is to be its object, we no longer distinguish between them; the two are recognised as one: we know, indeed, that there are two, but as we see them they have become one: this gives us the relation between the intellective subject and the object of intellection [in the duality and unity required by that primal intellection]: in our thought we have made the two into one; but on the other hand the one thing has become two, making itself into a duality at the moment of intellection, or, to be more exact, being dual by the fact of intellection and single by the fact that its intellectual object is itself.
