Where does the soul go after death, according to the great thinkers in the history of philosophy? In the Phaedo, Plato tells us how we present the soul for judgement after death, and how it resumes the form it had before birth. Plato also tells us how we present the soul for punishment in its period of renewed life, which is a time not so much of living but of expiation. However, while Plato said that the soul was immortal, his pupil Aristotle said that the soul, like the body, was subject to decay. While the Stoics believed in a limited and impersonal sort of immortality where after death the souls of the wise become one with the divine spirit permeating the world, for the Epicureans, who believed that everything was but a series of temporary groupings of atoms in the void, the soul was a grouping of atoms, and therefore destined to disintegrate after death. In his Enneads, Plotinus argues for Plato’s position by disproving the theories of all the other three positions. Plotinus devotes his time to show that the soul is indeed immortal by exploring what the nature of the soul is. He argues against the view that the soul is a body.
And so, the first order to business for the Neoplatonist philosophy of Platonis is to sketch the physiology of the soul: "The vehicles of touch are at the ends of the nerves and the nerves start from the brain; the brain has therefore been considered the seat and center of the principle which determines feeling and impulse and the entire act of the organism as a living thing, which the instruments are found to be linked, there the operating faculty is assumed to be situated." Re-reading the Phaedo, Plotinus concludes that the soul arises from the seat of sensation, the brain, to couple, combine and, finally, to blend, in memory and the sensible objects of experience. Although in a general sense Plotinus champions Plato's philosophy, he differs from Plato by rejecting the idea that the soul and body are mixtures of essentials; he says they are distinct entities.
In assessing these different viewpoints, Plotinus suggests that our fundamental alienation from ourselves consists in the fact that we do not have knowledge or perception; perhaps this theory simply means that the Good exists in and of itself; "it consists, not in the condition itself, but in the knowledge and perception of it"; the fourth condition is that, as a society, we can be diagnosed as having a collective psychotic disorder, in the sense that we are suffering from a whole body problem where we are fundamentally unaware of the deterioration of our collective health and that we are subject to mental delusions. In my opinion, the soul arises from the seat of sensation to couplement with the outer world and, finally, to blend in memory and the sensible objects of experience.
Plotinus says, "We are not to think of evil as some particular bad thing, such as injustice for example, but as a principle distinct from any of the particular forms in which it becomes manifest." In this harmonized universe where external evil and suffering take their place as necessary elements in the great pattern, the great dance of the universe, evil and suffering can affect humans’ lower selves but can only exceptionally, in a thoroughly depraved way, touch their true, higher selves and so cannot interfere with the real well-being of the philosopher. How do we explain the teaching that evils can never pass away but exist of necessity; that while evil has no place in the divine order, it haunts mortal nature and this place forever? Does this mean that heaven is clear of evil, ever moving its orderly way, spinning on the appointed path, no injustice there nor any flaw, no wrong done by any power to any other, while injustice and disorder prevail on earth? Some critics argue that many Neoplatonic concepts and ideas are ultimately derived from Christian Gnosticism during the third century in Lower Egypt, and that Plotinus himself may have been a Gnostic before nominally distancing himself from the movement.
Plotinus also says that "there is another principle establishing the necessary existence of evil; given that the good is not the only existent thing, it is inevitable that by the continuous down-going or away-going from it, there should be produced a Last, something after which nothing more can be produced, this will be evil." Here we see that Plotinus' project is Leibnizian in nature, his object is to structure a theodicy, a way to account for the presence of evil in the world. Plotinus uses various principles to be expostulated later by Leibniz to shed light on the very careful distinctions about the nature of the One that Plotinus articulates in the Enneads. As in the present context, Plotinus identifies the One with the Good beyond being and thus distinct from the form of the good in the intelligible. Plotinus takes these three terms, unity, the good and being, and applies them to the One, with transformations in their meaning that correspond in relation to the transcendent One. They are examined here, however, in relation to the One’s omnipresence, undergoing a similar fundamental change, moving from external to internal causes of things. Although he distinguishes between causes, Plotnius does not consider explicitly the omnipresence of the One in his analysis.
According to Plotinus, there are beings who are evil in the world and thus have no soul; soulless, these are the truly the untouchables; and thus the idea of an ideological purity is born from essentializing the human condition, as intellectual principles comes to be embodied in community-based language-bonds. As Plotinus says, "We come to the Gnostic doctrine which denies matter or, admitting it, denies its evil; we need not seek elsewhere; we may at once place evil in the Soul, recognizing it as the mere absence of Good." This radical distinction between our bodies and our spirits led Gnostics to twist the early church's understanding of who Jesus was and is. The Gnostics saw Jesus as a messenger bringing the special knowledge of salvation to humanity's imprisoned soul. They believed that when Jesus came to earth He didn't possess a body like our own; instead, the Gnostics taught that He only seemed to have a physical body. This was a denial of the Christian doctrine of the incarnation, the belief that Jesus was both fully God and fully human. But the Gnostics went even further: they also denied the bodily resurrection of Jesus, an event Paul argued must have taken place or our faith is in vain
There may me merit in the view that Plotinus promulgates a Neoplatonist worldview and a pre-Gnostic worldview, where the existence of evil fundamentally establishes the existence of the good and, vice versa, in an oppositional relation, they mark the same boundaries, setting up the ideological consciousness of the bicameral mind. Plotinus' conclusion is that evil exists in order to establish time as a memorial to the presence of Good. However, there remains the other half of Plotinus' question, regarding the administration of riches to the undeserving: since the good are in poverty while the wicked are wealthy, wouldn't that argue that, in God's kingdom on earth, his ordering is in reverse? Our resolved principle says that if there was no evil, then moral goodness wouldn't exist. According to Plotinus, moral goodness is a gift that has an essential relationship to the will of its bearer and recipient. As Joseph Conrad says, the bearer of a gift is entitled to his reward.
"This indicates the relation of the guiding spirit to ourselves; it is not entirely outside ourselves, it is bound up in our entire nature; it belongs to us as belonging to our very soul, but not insofar as we are human beings living a life to which it is superior." What is this Neoplatonic, pre-Gnostic reality which Plotinus bids us enter? It is this description of Spirit which saves us from falling into an even deeper evil, it is this power which consummates the chosen Life. In the face of the black man we find perfect finitude and, in the face of the white woman, perfect infinity; through the activities of the body, we can obtain knowledge of the immediate reality and true knowledge of the thing in itself. Plotinus says, "Matter is also an incorporeal substance; in this manner we must correct certain prevailing errors about authentic existence, about the ultimate essence of presence and about Being itself." It follows from all this that love, like our intellectual faculties, is concerned with absolute things (but we love most the mask which displays the face of infinity). As Plotinus says, "If we are sometimes advocates of the partial, that affection is not to be construed as direct but as only accidental, like our synthetic a priori judgment that a given triangular figure is composed from two right angles because the perfect triangle is absolutely so."
The turning away from material pleasures is made manifest in the faith of believers, an eternal existence among all existences, and blessed is the man who will eat at the feast in the kingdom of Heaven, for he shall have eternal life. "Still," Plotinus says, "this love is of a mixed quality: on the one hand there is in it the lack which keeps it craving and, on the other, it is not entirely destitute; as the deficient seeks more of what it has, and in the fact that certainly nothing which is absolutely void of the good would ever go seeking the Good." As it is said, to spring from poverty and dispossession, in the sense of one who lacks the good life and aspires to attain the will of reasoned principles, all present together in the soul, act so as to produce the good, which is Love. God will work all things together for the good of those who love Him. We are comforted with the knowledge that our decision to align our will with God's, and to always trust Him, will be rewarded.
