MacKenna-Plotinus: Highest Good

And, further, these Civic Virtues - measured and ordered themselves and acting as a principle of measure to the Soul which is as Matter to their forming - are like to the measure reigning in the over-world, and they carry a trace of that Highest Good in the Supreme; for, while utter measurelessness is brute Matter and wholly outside of Likeness, any participation in Ideal-Form produces some corresponding degree of Likeness to the formless Being There. And participation goes by nearness: the Soul nearer than the body, therefore closer akin, participates more fully and shows a godlike presence, almost cheating us into the delusion that in the Soul we see God entire. Enneads   I,2,2

Then why are these conditions sought and their contraries repelled by the man established in happiness? Here is our answer: These more pleasant conditions cannot, it is true, add any particle towards the Sage’s felicity: but they do serve towards the integrity of his being, while the presence of the contraries tends against his Being or complicates the Term: it is not that the Sage can be so easily deprived of the Term achieved but simply that he that holds the highest good desires to have that alone, not something else at the same time, something which, though it cannot banish the Good by its incoming, does yet take place by its side. Enneads I,4,7
