Matter becomes mistress of what is manifested through it: it corrupts and destroys the incomer, it substitutes its own opposite character and kind, not in the sense of opposing, for example, concrete cold to concrete warmth, but by setting its own FORMLESSNESS against the Form of heat, shapelessness to shape, excess and defect to the duly ordered. Thus, in sum, what enters into Matter ceases to belong to itself, comes to belong to Matter, just as, in the nourishment of living beings, what is taken in does not remain as it came, but is turned into, say, dog’s blood and all that goes to make a dog, becomes, in fact, any of the humours of any recipient. Enneads I,8,8
One thing perishes, and the Kosmic Reason – whose control nothing anywhere eludes – employs that ending to the beginning of something new; and, so, when the body suffers and the Soul, under the affliction, loses power, all that has been bound under illness and evil is brought into a new set of relations, into another class or order. Some of these troubles are helpful to the very sufferers – poverty and sickness, for example – and as for vice, even this brings something to the general service: it acts as a lesson in right doing, and, in many ways even, produces good; thus, by setting men face to face with the ways and consequences of iniquity, it calls them from lethargy, stirs the deeper mind and sets the understanding to work; by the contrast of the evil under which wrong-doers labour it displays the worth of the right. Not that evil exists for this purpose; but, as we have indicated, once the wrong has come to be, the Reason of the Kosmos employs it to good ends; and, precisely, the proof of the mightiest power is to be able to use the ignoble nobly and, given FORMLESSNESS, to make it the material of unknown forms. Enneads III,2,5
Its every utterance, therefore, is a lie; it pretends to be great and it is little, to be more and it is less; and the Existence with which it masks itself is no Existence, but a passing trick making trickery of all that seems to be present in it, phantasms within a phantasm; it is like a mirror showing things as in itself when they are really elsewhere, filled in appearance but actually empty, containing nothing, pretending everything. Into it and out of it move mimicries of the Authentic Existents, images playing upon an image devoid of Form, visible against it by its very FORMLESSNESS; they seem to modify it but in reality effect nothing, for they are ghostly and feeble, have no thrust and meet none in Matter either; they pass through it leaving no cleavage, as through water; or they might be compared to shapes projected so as to make some appearance upon what we can know only as the Void. Enneads III,6,7
In what sense, then, is it said to elude form? By very nature and for ever? But does not this precisely mean that it never ceases to be itself, in other words that its one form is an invincible FORMLESSNESS? In no other sense has Plato’s dictum any value to those that invoke it. Enneads III,6,13
