Brief Notes on Various Topics – 113
1. Thinking about a Plotinus Society
There are a number of Societies and Associations in the U.S. and the anglosphere that are dedicated to a particular philosopher or philosophical moement. There is one for William James, one for Immanuel Kant, and so forth. As I mentioned last week, I’ve been thinking of myself as a ‘Plotinian’ and following up on that I tentatively thought it would be a good idea to have a Plotinus Society, or the American Plotinus Society, or something like that. It would be devoted to the study and practice of Plotinus’s philosophy and way of life.
I would like to see a Plotinus society because I think Plotinus deserves that kind of focus. There is at this time an International Society for Neoplatonic Studies, but, leaving aside their troublesome use of the word ‘Neoplatonic’, the Society covers too wide a range of topics to have the understanding of Plotinus take center stage. I’d like to see Plotinus taken on his own terms rather than as part of a group that advocates for very different understandings of metaphysics, ethics, purification, and the nature of the philosophical ascent to the Good and the One.
A Plotinus Society would have the space to focus on what Plotinus means by contemplation, his understanding of purification, his view of the soul, and his view of mystical union with the Good and the One. Personally, I think the Enneads of Plotinus are unsurpassed as spiritual literature and deserve their own home.
2. Aetius
I recently became aware of a work of philosophy by the author Aetius. He wrote a book called ‘Placita’ which refers to a collection of views held by various philosophers at the time Aetius was writing. Placita was a genre of writing at that time. Nothing is known about Aetius. The collection is dated to the late first or early second century C.E., based on internal evidence such as the philosophers that are referred to.
The original work has been lost. But scholars have reconstructed more than 80% of the work; they base this 80% estimate on the structure of the book which has numbered sections and items. Long quotes from Aetius appear in several late classical writers and scholars and there are some Arabic sources as well. Scholars have pieced together these quotations and come up with a nearly complete collection. (As an aside, this is the kind of thing that leads me to admire the scholarly community. Such work requires a great deal of study and training and a very focused mind. I find it admirable and I am very grateful for the scholars who have done this kind of work.)
There are five sections: First Principles, Cosmology, Meteorology and the Earth, Psychology, and Physiology. Each of these five sections is then divided into multiple topics. Under each topic are pithy summaries of various philosophers. Most of these summaries are brief, but a few run to a full page or more. Here is an example from Section 4, Psychology, Topic 4, On the parts of the soul:
"4.4 On the Parts of the soul
1. Pythagoras and Plato according to their most general definition say that the soul is bipartite, for it has a rational part on the one hand and an irrational on the other. But according to what is proximate and precise it is tripartite, for they divide the irrational into the spirited and the concupiscible
2. Xenocrates says that one part of the soul is perceiving, and the other rational.
3. Aristotle said there are five activities of soul, the appetitive, the nurturing, the perceiving, the locomotive, the cogitating.
4. The Stoics say the soul consists of eight parts: five perceiving parts, viz. seeing, hearing, smelling, tasting, touching; as sixth the speaking part; as seventh the seminal part; as eighth the regent part itself, from which all these other parts are extended through their own organs, similarly to the tentacles of an octopus.
5. Apollophanes (says that the soul consists of nine parts).
6. The successors of Pythagoras, positing that the body is a blend of five elements – for to the four they added the ethereal element – said the powers of the soul too are in respect of this division equal in number, and these they called intelligence and understanding and knowledge and opinion and sensation."
(Aetius, Placita, translated by Jaap Mansfeld and David T. Runia, Loeb Classical Library, Harvard University Press, Cambridge, Massachusetts, 2023, pages 329-331, ISBN: 9780674997592)
Some topics have more items; for example, the previous item, Whether the soul is a body and what its substance is, has eleven summaries and some of those summaries contain multiple, maybe three to five, philosophers who share a common view. And some topics have fewer items and summaries.
What I like about Placita is that it offers the reader a summary overview of the various views on various topics that is easy to access and the collection benefits from being closer to the sources by many centuries than we are today. I quoted the topic about the parts of the soul because I have become very interested and focused on the complexity of the soul in the Platonic tradition and how that complexity carries through many centuries. What I find interesting in the above quote is that it seems that the complexity of the soul was a very widespread understanding, though the degree of the complexity varies. This allows me to understand that the complexity of the soul in Platonism wasn’t an outlier or something unique to the Platonic tradition.
I don’t exactly know how the book was used. But I can imagine it being something a teacher might use to track down a reference when asked a question about a specific topic. It has the feeling of a catalog or an appendix.
Plato is frequently presented on the various topics and because of this it is possible to learn what some people in the late first or early second century understood to be Platonic views; and at the same time the reader can contrast those with those of others. There are also references to early Platonists such as Xenocrates, as in the quote above. Because of the structure of the book, you can look up specific topics, turn to that topic, and then find out what people considered to be the Platonic interpretation, along with the interpretations of others. I find the organization of the book to be remarkably well constructed. For those interested in Platonism at that time I think this is very helpful.
3. Starting Points
One way of looking at Platonism, or any spiritual or philosophical tradition is by determining the starting point of that tradition. By ‘starting point’ I mean something like a First Principle, a basic statement that functions like the foundation of a building. Sometimes that is easy to determine because a tradition might be explicit about stating their starting point, or their first principle. ‘Jesus is Lord’ is a good example from the Christian tradition. In Buddhism the First Noble Truth is that life is suffering which functions as the starting point out of which other insights and practices grow. In Platonism there is the view that the first principle is the Good and the One. Starting Points don’t necessarily make things simple because different members of the tradition may interpret the starting point, or first principle, differently. But having such a starting point simplifies discussions about the tradition by clearly articulating its foundation and by distinguishing a tradition from another tradition that has a different starting point.
It seems to me that starting points, or first principles, are most often metaphysical in nature. But they can also be ethical in nature. For example, in the Jain tradition non-harming, or Ahimsa, is the starting point. Non-harming is an ethical commitment rather than a metaphysical statement regarding the nature of existence. In Jainism all the other insights and practices flow from the ethical principle of non-harming/Ahimsa.
And here I’d like to raise the question regarding Platonism whether its first principle, or starting point, is metaphysical or ethical. (I recognize that the separation of ethics and metaphysics has its own problems; but for the purposes of this post, I’m going to treat them as different in that an ethical starting point does not, in itself, determine a metaphysical position, and vice versa. I mean that individuals can be committed to non-harming and at the same time adhere to different metaphysical commitments. For example, both Jainism and Classical Yoga are committed to Non-harming/Ahimsa, but they have different metaphysical views.)
When I ask this question, I am contrasting in my own mind the idea that the Good and the One are the first principle of Platonism in contrast to asserting that non-harming, or justice (which Plato equates with non-harming) is the first principle. I think the norm is to assert that the Good and the One is the First Principle and the starting point for Platonism. This partially explains why the teachings on non-harming found in Platonism are not treated as extensively as the metaphysics of Platonism.
In the history of Platonism, the Platonist who comes closest, it seems to me, to viewing non-harming as the, or a, first principle is Porphyry, particularly in his work On Abstinence. But one can also see this stance in Porphyry’s Letter to Anebo. I don’t mean that Porphyry explicitly states that non-harming is the first principle of Platonism. He doesn’t do that. But what I am suggesting is that it makes sense to interpret a work like On Abstinence as functionally equivalent to regarding non-harming as the first principle of Platonism, as Platonism’s starting point. I say this because Porphyry links the focus of that work, vegetarianism, to contemplation, to the nature of soul, to purification, and many other topics which is typical of how a first principle works; kind of like an axiom in geometry. (For those interested in Porphyry’s perspective I recommend Book III, paragraphs 26 and 27 of On Abstinence which are found on pages 97 and 98 in the translation by Gillian Clark.)
Scholars don’t see On Abstinence in this way, as an elaboration of non-harming as a first principle; on the other hand, scholars tend to have come to the conclusion that the Good and the One is the first principle, so they wouldn’t be looking for another candidate. (As an aside, I understand why people, many people, regard the Good and the One as the first principle of Platonism; there is a lot of writing that is consistent with that presentation that can be found in early sources such as Plato and Aristotle and so forth over many centuries. I’m not dismissing that out of hand. In a way I’m offering the idea that non-harming is the first principle of Platonism as a kind of thought experiment to see where it would lead; perhaps viewing non-harming as the first principle of Platonism will clarify some issues or bring certain insights forward that we have not observed clearly in the past. That’s my hope, but we shall see.)
If non-harming is the first principle, the ultimate starting point, of Platonism how would that impact the place that the Good and the One hold? I suspect that if we take non-harming as the first principle then the Good and the One, along with the metaphysical cosmology of Platonism, become inferences (broadly speaking) from the axiom, or starting point, or first principle of non-harming. In other words, the Good and the One, as understandings, are subsequent to the intuition, the insight, the primal source of non-harming.
I think there exist good textual reasons for looking at non-harming this way in a Platonist context; particular in the dialogue Crito. This dialogue depicts Socrates as so committed to non-harming that he is willing to die rather than forgoing its teaching. And in several dialogues, it is stated that it is better to suffer an injustice/harm than it is to commit an injustice, even in retaliation. This kind of writing is powerful and can be understood as saying that the ethical commitment of non-harming is the primary teaching, the starting point, of Platonic teachings.
4. Aphorisms --
The geraniums of time.
There is something a bit humorous in writing about eternity using an aphorism.
You cannot use the same word twice.
In the philosophical ascent some things become clearer and at the same time other things become more mysterious.
All nations are unstable.
Grace is the atmospheric condition that allows philosophy to happen.
Philosophical analysis is not an end in itself.
Poetry is a craft like baking bread or sewing quilts.
In my old age I find that I am content and I think that is due to decades of spiritual practice.
The gods are not immortal.
I’m probably in the minority on this point; but I don’t regard a human birth as particularly auspicious in terms of spiritual development, understanding, and realization.
There is a place, or, better, a presence, that I have come to call the ‘grotto of eternity.’
