But why does the existence of the Principle of Good necessarily comport the existence of a Principle of Evil? Is it because the All necessarily comports the existence of Matter? Yes: for necessarily this All is made up of contraries: it could not exist if Matter did not. The Nature of this Kosmos is, therefore, a blend; it is blended from the Intellectual-Principle and Necessity: what comes into it from God is good; evil is from the Ancient Kind which, we read, is the underlying Matter not yet brought to order by the Ideal-Form. Enneads I,8,7
Why are not beauty, goodness and the virtues, together with knowledge and intelligence, included among the primary genera? If by goodness we mean The First – what we call the Principle of Goodness, the Principle of which we can predicate nothing, giving it this name only because we have no other means of indicating it – then goodness, clearly, can be the genus of nothing: this principle is not affirmed of other things; if it were, each of these would be Goodness itself. The truth is that it is prior to Substance, not contained in it. If, on the contrary, we mean goodness as a quality, no quality can be ranked among the primaries. Enneads VI,2,17
It is with Number as with Good. When we pronounce things to be good either we mean that they are in their own nature so or we affirm goodness as an accidental in them. Dealing with the primals, the goodness we have in mind is that First Hypostasis; where the goodness is an accidental we imply the existence of a Principle of Good as a necessary condition of the accidental presence; there must be some source of that good which is observed elsewhere, whether this source be an Absolute Good or something that of its own nature produces the good. Similarly with number; in attributing the decad to things we affirm either the truly existent decad or, where the decadhood is accidental, we necessarily posit the self-subsistent decad, decad not associated; if things are to be described as forming a decad, then either they must be of themselves the decad or be preceded by that which has no other being than that of decadhood. Enneads VI,6,10
That Life, the various, the all-including, the primal and one, who can consider it without longing to be of it, disdaining all the other? All other life is darkness, petty and dim and poor; it is unclean and polluting the clean for if you do but look upon it you no longer see nor live this life which includes all living, in which there is nothing that does not live and live in a life of purity void of all that is ill. For evil is here where life is in copy and Intellect in copy; There is the archetype, that which is good in the very Idea – we read – as holding The Good in the pure Idea. That Archetype is good; Intellectual-Principle is good as holding its life by contemplation of the archetype; and it sees also as good the objects of its contemplation because it holds them in its act of contemplating the Principle of Good. But these objects come to it not as they are There but in accord with its own condition, for it is their source; they spring thence to be here, and Intellectual-Principle it is that has produced them by its vision There. In the very law, never, looking to That, could it fail of Intellectual Act; never, on the other hand, could it produce what is There; of itself it could not produce; Thence it must draw its power to bring forth, to teem with offspring of itself; from the Good it takes what itself did not possess. From that Unity came multiplicity to Intellectual-Principle; it could not sustain the power poured upon it and therefore broke it up; it turned that one power into variety so as to carry it piecemeal. Enneads VI,7,15
But if Matter by very essence is evil how could it choose the good? This question implies that if Evil were self-conscious it would admire itself: but how can the unadmirable be admired; and did we not discover that the good must be apt to the nature? There that question may rest. But if universally the good is Form and the higher the ascent the more there is of Form-Soul more truly Form than body is and phases of soul progressively of higher Form and Intellectual-Principle standing as Form to soul collectively – then the Good advances by the opposite of Matter and, therefore, by a cleansing and casting away to the utmost possible at each stage: and the greatest good must be there where all that is of Matter has disappeared. The Principle of Good rejecting Matter entirely – or rather never having come near it at any point or in any way – must hold itself aloft with that Formless in which Primal Form takes its origin. But we will return to this. Enneads VI,7,28
