Now comes the question what sort of thing does the Intellectual-Principle see in seeing the Intellectual Realm and what in seeing itself? We are not to look for an Intellectual realm reminding us of the colour or shape to be seen on material objects: the intellectual antedates all such things; and even in our sphere the production is very different from the Reason-Principle in the seeds from which it is produced. The seed principles are invisible and the beings of the Intellectual still more characteristically so; the INTELLECTUALS are of one same nature with the Intellectual Realm which contains them, just as the Reason-Principle in the seed is identical with the soul, or life-principle, containing it. Enneads V,3,8
As to the How of participation, the enquiry is that of all participation in Ideal Forms; we must note, however, that the presence of the Decad in the looser totals is different from its presence in the continuous; there is difference again in its presence within many powers where multiplicity is concentred in unity; arrived at the INTELLECTUALS, there too we discover Number, the Authentic Number, no longer entering the alien, Decad-Absolute not Decad of some particular Intellectual group. Enneads VI,6,14
In the INTELLECTUALS, all, if the Absolute Living-Form, there is a multiple – a triad, let us say – that Triad of the Living-Form is of the nature of essence: and the Triad prior to any living thing, Triad in the realm of Being, is a principle of essence. Enneads VI,6,16
