MacKenna-Plotinus: individual soul

Next there is the conception of the individual soul as a part in the sense in which we speak of some single proposition as a part of the science entire. Enneads   IV,3,2

So it is with the individual souls; the appetite for the divine Intellect urges them to return to their source, but they have, too, a power apt to administration in this lower sphere; they may be compared to the light attached upwards to the sun, but not grudging its presidency to what lies beneath it. In the Intellectual, then, they remain with soul-entire, and are immune from care and trouble; in the heavenly sphere, absorbed in the soul-entire, they are administrators with it just as kings, associated with the supreme ruler and governing with him, do not descend from their kingly stations: the souls indeed [as distinguished from the kosmos] are thus far in the one place with their overlord; but there comes a stage at which they descend from the universal to become partial and self-centred; in a weary desire of standing apart they find their way, each to a place of its very own. This state long maintained, the soul is a deserter from the All; its differentiation has severed it; its vision is no longer set in the Intellectual; it is a partial thing, isolated, weakened, full of care, intent upon the fragment; severed from the whole, it nestles in one form of being; for this, it abandons all else, entering into and caring for only the one, for a thing buffeted about by a worldful of things: thus it has drifted away from the universal and, by an actual presence, it administers the particular; it is caught into contact now, and tends to the outer to which it has become present and into whose inner depths it henceforth sinks far. Enneads IV,8,4

The soul’s operation is similar: its next lower act is this universe: its immediate higher is the contemplation of the Authentic Existences. To individual souls such divine operation takes place only at one of their phases and by a temporal process when from the lower in which they reside they turn towards the noblest; but that soul, which we know as the All-Soul, has never entered the lower activity, but, immune from evil, has the property of knowing its lower by inspection, while it still cleaves continuously to the beings above itself; thus its double task becomes possible; it takes thence and, since as soul it cannot escape touching this sphere, it gives hither. Enneads IV,8,7

But why are not all the powers of this unity present everywhere? The answer is that even in the case of the individual soul described, similarly, as permeating its body, sensation is not equally present in all the parts, reason does not operate at every point, the principle of growth is at work where there is no sensation - and yet all these powers join in the one soul when the body is laid aside. Enneads IV,9,3

If Socrates  , Socrates’ soul, is external then the Authentic Socrates - to adapt the term - must be There; that is to say, the individual soul has an existence in the Supreme as well as in this world. If there is no such permanent endurance and what was Socrates may with change of time become another soul and be Pythagoras   or someone else - then the individual Socrates has not that existence in the Divine. Enneads V,7,1

Are we, then, to rank the individual soul, as containing these Reason-Principles, with Sensible Substance? But we do not even identify the Principles with body; we merely include them in Sensible Quality on the ground that they are connected with body and are activities of body. The constituents of Sensible Substance have already been specified; we have no intention whatever of adding to them Substance bodiless. Enneads VI,3,16

As for Qualities, we hold that they are invariably bodiless, being affections arising within Soul; but, like the Reason-Principles of the individual soul, they are associated with Soul in its apostasy, and are accordingly counted among the things of the lower realm: such affections, torn between two worlds by their objects and their abode, we have assigned to Quality, which is indeed not bodily but manifested in body. Enneads VI,3,16
