Diogenes Laertius
I recently reread the chapter on Plato from Lives of the Eminent Philosophers by Diogenes Laertius. Scholars say that Diogenes was a third century writer; his dates are never explicitly stated in his book, but the inference for a third century attribution seems fairly solid. This would make Diogenes a contemporary of Plotinus, though Plotinus does not appear in his work. Diogenes was mostly concerned with ancient philosophy, its beginning and the most influential philosophers who still, at the time Diogenes was writing, had significant influence.
Scholars suggest that Diogenes himself was an Epicurean; this is based primarily on the very lengthy treatment of Epicurus which appears in Book X and includes long quotations from primary sources.
Diogenes over the centuries has had an up and down reputation. His book is often the only source we have for some philosophers so Diogenes can’t be overlooked. But critics sometimes suggest that Diogenes lacked discrimination as to what was important and what was not when he wrote about certain philosophers. The chief objection seems to be that Diogenes will report unverified stories that may be nothing more than gossip.
In reading the chapter on Plato I had a kind of realization about Diogenes that I’d like to share. It came to me that the chapters on various philosophers found in his work remind me of portraits of people that I used to read in ‘The New Yorker’ magazine. I haven’t looked at The New Yorker in a long time, so I’m not sure that it still publishes this type of writing; but I’m referring to long, say as long as sixty pages, portraits of famous and/or influential people. Usually these people were involved with the arts in some way; as musicians or composers, writers, poets, critics, and so forth. The New Yorker would interview the person, but they would also contact people close to the person and sometimes report stories from such sources. I wouldn’t call this gossip, though at times it could drift in that direction.
I don’t think Diogenes had what today we would call an academic audience in mind. And it doesn’t seem that Diogenes was concerned with the kind of demands that historians today place on themselves in terms of including scholarly apparatus such as footnotes, endnotes, bibliography, and other types of references. This is not entirely absent; often Diogenes will name his source and then quote from it. And at other times Diogenes will list the works that a particular philosopher wrote which gives us a good idea of the scope of the philosopher’s work (see, for example, his portrait of Xenocrates.) But at other times he doesn’t and perhaps the story he is telling us at that time was just a widely known, or believed, story about that particular philosopher with no secure source.
I think the audience Diogenes had in mind would be an educated literary person who wanted a quick, but knowledgeable, overview of their culture’s philosophical heritage without going into too great detail about difficult and complex topics. Looked at in this way I think Lives is successful and remains a valuable source of information today.
I think that reading Diogenes’s portrait of Plato gives us a good idea of what Middle Platonists understood to be Platonic doctrine. Sometimes Diogenes offers surprising insights. For example, in his section on the creation of the material world, which is based on frequent quotes from Timaeus, Diogenes writes,
“In order that time might exist, the sun, moon, and planets were created. . . . And in order that the universe, which had been created in the likeness of the intelligible being, might be complete, the nature of all other animals was created. Since its pattern contains them, the universe must also contain them. And thus it has gods, which are primarily fiery in nature, and three other kinds of creatures: the winged, the aquatic, and the terrestrial.”
(Diogenes Leartius, Lives of the Eminent Philosophers, translated by Pamela Mensch, edited by James Miller, Oxford University Press, 2018, pages 164-165, ISBN: 97801908621760)
What I find interesting in this passage is that Diogenes places the gods with ‘other kinds of creatures’ of the material world. This implies that the gods are what I refer to as ‘third things.’ By ‘third things’ I mean things of the third level, or hypostasis, of the Platonic cosmology, the material world. Here is a quote from Timaeus that Diogenes bases his own writing on:
“Prior to the coming to be of time, the universe had already been made to resemble in various respects the model in whose likeness the god was making it, but the resemblance still fell short in that it didn’t yet contain all the living things that were to have come to be within it. This remaining task he went on to perform, casting the world into the nature of its model. And so he determined that the living things as those which, according to the discernment of Intellect, are contained within the real Living Thing. Now there are four of these kinds: first, the heavenly race of gods; next, the kind that has wings and travels through the air; third, the kind that lives in water; and fourth, the kind that has feet and lives on land.”
(Plato, Timaeus, translated by Donald J. Zeyl, Plato: Complete Works, edited by John Cooper, Hackett Publishing Company, Indianapolis, 1997, page 1243, 39e, ISBN: 9780872203495)
I see this as Diogenes correctly teaching that the gods, as opposed to the god, are created (by the Demiurge) as one of the four types of living beings in the material world. This is fascinating to me. Again, I think this teaches that the gods are third things rather than the later interpretation that the gods are henads. And there are other equally insightful passages in Diogenes’s presentation of Plato’s thought.
Another aspect of Diogenes writing on Plato I like is that Diogenes presents two arrangements of the Dialogues which seem to have been used at the time Diogenes wrote. One consists of tetralogies which Diogenes lists along with their contents and, often, alternate names of the dialogues that were in use at the time, such as The Statesman which was also called On Monarchy and Phaedo which was also titled On the Soul. The second consists of groupings into trilogies. In this section Diogenes also discusses ‘spurious’ dialogues even suggesting in one case the actual author.
Diogenes collects certain brief quotes about Plato, such as, “He advised those who were drunk to look at themselves in the mirror; for they would then abstain from such unseemly conduct.” And “He spent most of his time in seclusion, according to some writers.” (These are from page 152 of the Mensch translation.) This is the only reference I have found that suggests that Plato spent ‘most of his time’ in seclusion. It is an unattributed comment. Perhaps this refers to the need for writers to have a lot of alone time, or perhaps it refers to a contemplative life.
(As an aside, the section where Diogenes collects remarks about Plato reminds a little of Plutarch and his collections of sayings. I wonder if Diogenes was influenced by Plutarch?)
Diogenes closes his chapter on Plato with a summary of Platonic doctrine. This gives us a good window into how Platonism was understood at that time. Diogenes does this by having paragraphs about types of friendship, forms of government, kinds of knowledge, kinds of medicine, kinds of law, and so forth.
I think the chapter on Plato written by Diogenes belongs with the Handbook by Alcinous, the Orations of Maximus, and Plutarch’s writings that are pertinent to Platonism. It tells us a lot about the life and thought of Plato as understood by Diogenes and, by extension, the people of the time in which Diogenes lived. I think it is a very good introduction to both Plato and Platonism and it is well worth reading.
