If sensation is apprehension by means of the soul’s employment of the body, intellection cannot be a similar use of the body or it would be identical with sensation. If then intellection is apprehension apart from body, much more must there be a distinction between the body and the intellective principle: sensation for objects of sense, intellection for the intellectual object. And even if this be rejected, it must still be admitted that there do exist intellections of intellectual objects and perceptions of objects not possessing magnitude: how, we may then ask, can a thing of magnitude know a thing that has no magnitude, or how can the partless be known by means of what has parts? We will be told “By some partless part.” But, at this, the intellective will not be body: for contact does not need a whole; one point suffices. If then it be conceded – and it cannot be denied – that the primal intellections deal with objects completely incorporeal, the principle of intellection itself must know by virtue of being, or becoming, free from body. Even if they hold that all intellection deals with the ideal forms in Matter, still it always takes place by abstraction from the bodies (in which these forms appear) and the separating agent is the Intellectual-Principle. For assuredly the process by which we abstract circle, triangle, line or point, is not carried through by the aid of flesh or Matter of any kind; in all such acts the soul or mind must separate itself from the material: at once we see that it cannot be itself material. Similarly it will be agreed that, as beauty and justice are things without magnitude, so must be the intellective act that grasps them. Enneads IV,7,
All turns on the identity. The intellectual object is itself an activity, not a mere potentiality; it is not lifeless; nor are the life and intellection brought into it as into something naturally devoid of them, some stone or other dead matter; no, the intellectual object is essentially existent, the primal reality. As an active force, the first activity, it must be, also itself, the noblest intellection, intellection possessing real being since it is entirely true; and such an intellection, primal and primally existent, can be no other than the primal PRINCIPLE OF INTELLECTION: for that primal principle is no potentiality and cannot be an agent distinct from its act and thus, once more, possessing its essential being as a mere potentiality. As an act – and one whose very being is an act – it must be undistinguishably identical with its act: but Being and the Intellectual object are also identical with that act; therefore the Intellectual-Principle, its exercise of intellection and the object of intellection all are identical. Given its intellection identical with intellectual object and the object identical with the Principle itself, it cannot but have self-knowledge: its intellection operates by the intellectual act which is itself upon the intellectual object which similarly is itself. It possesses self-knowing, thus, on every count; the act is itself; and the object seen in that act – self, is itself. Enneads V,3,
But do not we ourselves assert that the Beings There are essence and Act? The Beings, yes, but they are to us manifold and differentiated: the First we make a simplex; to us Intellection begins with the emanant in its seeking of its essence, of itself, of its author; bent inward for this vision and having a present thing to know, there is every reason why it should be a PRINCIPLE OF INTELLECTION; but that which, never coming into being, has no prior but is ever what it is, how could that have motive to Intellection? As Plato rightly says, it is above Intellect. Enneads VI,7,
