The Intellectual-Principle on the other hand was never merely the Principle of an inviolable unity; it was a universal as well and, being so, was the Intellectual-PRINCIPLE OF ALL things. Being, thus, all things and the PRINCIPLE OF ALL, it must essentially include this part of itself (this element-of-plurality) which is universal and is all things: otherwise, it contains a part which is not Intellectual-Principle: it will be a juxtaposition of non-Intellectuals, a huddled heap waiting to be made over from the mass of things into the Intellectual-Principle! Enneads III,8,8
Whence must such a sequent arise? It must be an offspring of The First; for suppose it the product of chance, that First ceases to be the Principle of All. Enneads V,4,1
But (it will be objected) if this were a matter of mere thinking we might well admit that the intellectual concept, remaining concept, should take in the unintellectual, but where concept is identical with thing how can the one be an Intellection and the other without intelligence? Would not this be Intellect making itself unintelligent? No: the thing is not unintelligent; it is Intelligence in a particular mode, corresponding to a particular aspect of Life; and just as life in whatever form it may appear remains always life, so Intellect is not annulled by appearing in a certain mode. Intellectual-Principle adapted to some particular living being does not cease to be the Intellectual-PRINCIPLE OF ALL, including man: take it where you will, every manifestation is the whole, though in some special mode; the particular is produced but the possibility is of all. In the particular we see the Intellectual-Principle in realization; the realized is its latest phase; in one case the last aspect is “horse”; at “horse” ended the progressive outgoing towards the lesser forms of life, as in another case it will end at something lower still. The unfolding of the powers of this Principle is always attended by some abandonment in regard to the highest; the outgoing is by loss, and by this loss the powers become one thing or another according to the deficiency of the life-form produced by the failing principle; it is then that they find the means of adding various requisites; the safeguards of the life becoming inadequate there appear nail, talon, fang, horn. Thus the Intellectual-Principle by its very descent is directed towards the perfect sufficiency of the natural constitution, finding there within itself the remedy of the failure. Enneads VI,7,9
If we cannot but speak of Happening we must not halt at the word but look to the intention. And what is that? That the Supreme by possession of a certain nature and power is the Principle. Obviously if its nature were other it would be that other and if the difference were for the worse it would manifest itself as that lesser being. But we must add in correction that, as Principle of All, it could not be some chance product; it is not enough to say that it could not be inferior; it could not even be in some way good, for instance in some less perfect degree; the Principle of All must be of higher quality than anything that follows it. It is therefore in a sense determined – determined, I mean, by its uniqueness and not in any sense of being under compulsion; compulsion did not co-exist with the Supreme but has place only among secondaries and even there can exercise no tyranny; this uniqueness is not from outside. Enneads VI,8,9
The answer is that we utterly must not speak of Him as made but sheerly as maker; the making must be taken as absolved from all else; no new existence is established; the Act here is not directed to an achievement but is God Himself unalloyed: here is no duality but pure unity. Let no one suspect us of asserting that the first Activity is without Essence; on the contrary the Activity is the very reality. To suppose a reality without activity would be to make the PRINCIPLE OF ALL principles deficient; the supremely complete becomes incomplete. To make the Activity something superadded to the essence is to shatter the unity. If then Activity is a more perfect thing than essence and the First is all perfect, then the Activity is the First. Enneads VI,8,20
We are in search of unity; we are to come to know the principle of all, the Good and First; therefore we may not stand away from the realm of Firsts and lie prostrate among the lasts: we must strike for those Firsts, rising from things of sense which are the lasts. Cleared of all evil in our intention towards The Good, we must ascend to the Principle within ourselves; from many, we must become one; only so do we attain to knowledge of that which is Principle and Unity. We shape ourselves into Intellectual-Principle; we make over our soul in trust to Intellectual-Principle and set it firmly in That; thus what That sees the soul will waken to see; it is through the Intellectual-Principle that we have this vision of The Unity; it must be our care to bring over nothing whatever from sense, to allow nothing even of soul to enter into Intellectual-Principle: with Intellect pure, and with the summit of Intellect, we are to see the All-Pure. Enneads VI,9,3
