[2.4.2] Plotinus: Neoplatonist Metaphysics

“Plotinus (204-270 AD) is considered to be the founder of Neoplatonism. Taking his lead from his reading of Plato, Plotinus developed a complex spiritual cosmology involving three foundational elements: the One, the Intelligence, and the Soul. It is from the productive unity of these three Beings that all existence emanates, according to Plotinus. The principal of emanation is not simply causal, but also contemplative. In his system, Plotinus raises intellectual contemplation to the status of a productive principle; and it is by virtue of contemplation that all existents are said to be united as a single, all-pervasive reality.”

The following OntoUML diagram shows the main entities in the metaphysical scheme of Plotinus.

Class/(Package)
Description
TheOne_
TheGood
“the One, which is neither being nor essence, but the source, or rather, the possibility of all existence. In this capacity, the One is not even a beginning, nor even an end, for it is simply the disinterested orientational ‘stanchion’ that permits all beings to recognize themselves as somehow other than a supreme ‘I’…” Is in 1:1 relation with the Intellect;
Intellect“The Intelligence (Nous) is the true first principle — the determinate, referential ‘foundation’ (arkhe) — of all existents; for it is not a self-sufficient entity like the One, but rather possesses the ability or capacity to contemplate both the One, as its prior, as well as its own thoughts, which Plotinus identifies with the Platonic Ideas or Forms (eide)… The Intelligence may be understood as the storehouse of potential being(s), but only if every potential being is also recognized as an eternal and unchangeable thought in the Divine Mind (Nous). Plotinus states that “to think and to be are one and the same” Existentially depending
on the TheOne_
TheGood; contains a multitude of Forms(p).
Form“The Ideas (Forms) reside in the Intelligence as objects of contemplation. Plotinus states that: “No Idea is different from The Intelligence but is itself an intelligence”
HigherSoul“The Soul, like the Intelligence, is a unified existent, in spite of its dual capacity as contemplator and actor. The purely contemplative part of the Soul, which remains in constant contact with the Intelligence, is referred to by Plotinus as the ‘higher part’ of the Soul1:1 relation with Intellect; on which existentially depends. Contains LogoiSpermatikoi.
Logoi
Spermatikoi
“through the contemplation of the One via the (Forms) Ideas, the Intelligence produces the logoi spermatikoi (‘seminal reasons’) that will serve as the productive power or essence of the Soul, which is the active or generative principle within Being.”LogoiSpermatikoi are a combination of Forms (many:many – 0..*:1..* relation).
Human “What Plotinus calls the “living being” (zoon) is what we would refer to, roughly, as the human being, or the individual possessed of a distinct personality. This being is the product of the union of the lower or active part of the soul with a corporeal body… Each “particular being” is the product, as it were, of an intelligence (a logos spermatikos)”
LowerSoul
“that part which actively descends into the changeable (or sensible) realm in order to govern and directly craft the Cosmos, is the ‘lower part (of the Soul),’ which assumes a state of division as it enters, out of necessity, material bodies… Yet the lower (or active), governing part of the Soul, while remaining, in its essence, a divine being and identical to the Highest Soul, nevertheless, through its act, falls into forgetfulness of its prior, and comes to attach itself to the phenomena of the realm of change, that is, of Matter.” Is part of the HigherSoul; associated with a CorporealBody.
CorporealBody CorporealBody is part of the Matter, made of Matter.
MatterMatter, for Plotinus, may be understood as an eternally receptive substratum (hupokeimenon), in and by which all determinate existents receive their form. Since Matter is completely passive, it is capable of receiving any and all forms, and is therefore the principle of differentiation among existents.”

OBSERVATION: according to my sources Plotinus’s thinking about the granularity of Forms/Ideas is not clarified, meaning if there is a different Form for any specific Particular, like any human being or not. (E.g.: is there a separate Form for Socrates or not?).
To overcome this issue I set one-one multiplicity for the LogoiSpermatikoi-LowerSoul_IndividualSoul relation, presuming that the HigherSoul is the level where the individual LowerSouls for different LivingBeings are created; and I used many-many multiplicity for the Form-
LogoiSpermatikoi relation, supposing that the Intellect thinks in higher categories (e.g. Humans, Genders etc.)

You can find a related post about [1.2.1] Plato’s Forms here. It is interesting to observe the increased complexity of Plotinus’s system.

[2.2.6] Stoic Cosmology

For the Stoics, the universe:

  • is a unitary spherical body located in the void, with properties resembling those of a living being,
  • can be entirely explained by two principles, the active pneuma and the passive matter,
  • has a life cycle consisting of three ever-repeating phases, characterized by the dominance of fire (conflagration), of elements, and of bodies (in the present period).

The stoic cosmological model is using concepts from stoic ontology [2.2.5] and psychology [2.2.1].

The OntoUML diagram below presents the structure of the stoic universe:

Stoic cosmology
ClassDescriptionRelations
Universe“The governing metaphor for Stoic cosmology is biological, in contrast to the fundamentally mechanical conception of the Epicureans. The entire cosmos [universe] is a living thing and God stands to the cosmos as an animal’s life force stands to the animal’s body, enlivening, moving and directing it by its presence throughout. The Stoics insistence that only bodies are capable of causing anything, however, guarantees that this cosmic life force must be conceived of as somehow corporeal.”
UniversOnFire;
UnverseOfElements;
PresentUniverse
“Just as living things have a life-cycle that is witnessed in parents and then again in their off-spring, so too the universe has a life cycle that is repeated. This life cycle is guided by, or equivalent to, a developmental plan that is identified with God. There is a cycle of endless recurrence, beginning from a state in which all is fire, through the generation of the elements, to the creation of the world we are familiar with, and eventually back to the state of pure designing fire called the conflagration’” UniversOnFire,
UnverseOfElements,

PneumaGod is identified with an eternal reason or intelligent designing fire or a breath (pneuma) which structures matter in accordance with Its plan. The designing fire is likened to sperm or seed which contains the first principles or directions of all the things which will subsequently develop. The biological conception of God as a kind of living heat or seed from which things grow seems to be fully intended. The further identification of God with pneuma or breath may have its origins in medical theories of the Hellenistic period…
More specifically, God is identical with one of the two ungenerated and indestructible first principles (archai) of the universe.”

Pneuma comes in gradations and endows the bodies which it pervades with different qualities as a result. The pneuma which sustains an inanimate object is a tenor (hexis, lit. a holding). Pneuma in plants is, in addition, physique (phusis, lit. nature). In animals, pneuma is soul (psychê) and in rational animals pneuma is, besides, the [central] commanding faculty (hêgemonikon) – that is responsible for thinking, planning, deciding. The Stoics assign to ‘physique’ or ‘nature’ all the purely physiological life functions of a human animal (such as digestion, breathing, growth etc.) – self-movement from place to place is due to soul. Tenor, Nature, Soul,
CentralCommandingFaculty are subkinds of Pneuma;

Matter “One principle [of the Universe] is matter which they regard as utterly unqualified and inert. It is that which is acted upon.” is contained by the Universe and Body
Body “Only bodies (σώματα, sômata) have being, or exist. Slogan: to exist is to have causal powers. Plato in the Sophist (247d–e): ‘Now, I say that what has some power to make something else into something, or to suffer the slightest, even once, this has real being. For I define being as nothing but power (δύναμις).’ The Stoic conception of existence is thus dynamic. Matter as such is passive, but bodies are not, since they are also infused by logos, which is active… only bodies can act or be acted upon” is part of the PresentUniverse
