I have now expanded the old comparison chart we had on the forum through the use of Claude AI to include columns for the Socratics and the Aristotelians. For the new additions I haven't checked each of the sources that that are listed for each point on the chart, but the issue summaries themselves appear to be a very good start.

This chart is something that we've needed for a very long time, and we need to bring our Epicurean expertise to improving it beyond what is possible through AI alone. It appears to me that Claude has already to some extent picked up from the material I already had on Epicurus and the Stoics a general tone of comparison that is valid, but I invite comments and suggestions on improving both the summaries and the citations. We need to edit these observations from an Epicurean perspective to help make sure that the divisions are highlighted as starkly and clearly as possible.

I am going to update the master comparison table (which at present is oriented toward comparing with Stoicism and repost it shortly. I will add Aristotle and also the Socratics.

I've prepared a new page to make it easier for browsers of the page to identify to what extent they fit with Epicurean Philosophy. This is a first draft which will change, but it's already in usable form. This stems primarily from the recent material we've been covering on the podcast which stresses the difference between Epicurus and the Socratic philosphers as to the role of natural science, so that's question one on this tree:

And yet Archimedes possessed such a lofty spirit, so profound a soul, and such a wealth of scientific theory, that although his inventions had won for him a name and fame for superhuman sagacity, he would not consent to leave behind him any treatise on this subject, but regarding the work of an engineer and every art that ministers to the needs of life as ignoble and vulgar, he devoted his earnest efforts only to those studies the subtlety and charm of which are not affected by the claims of necessity.

So at least partially at the feet of the Socratic-Pythagorean axis and their deprecation of "natural science" we can lay the charge that they held back one of the greatest engineering minds of the ancient world from further practical discoveries.

Absolutely disgusting to think about.

It's beginning to be clear that the Socratic position mentioned by Diogenes of Oinoanda as being opposed to the study of natural science constitute a major bright line division between them and Epicurus. Apparently that same distinction did not exist between Epicurus and the Stoics. Pending confirmation here's an AI summary:

Quote

In contrast to Socrates, the Stoics regarded the study of natural science (physikē) as not only desirable but philosophically necessary.

For the Stoics—beginning with Zeno of Citium and systematized by thinkers such as Chrysippus—philosophy was divided into three interdependent parts: logic, ethics, and physics. Physics, which included cosmology, theology, and the study of nature as a rational, ordered whole, was essential because it grounded ethics. One could not fully understand how to live well without understanding how the universe itself is structured and governed.

The Stoics held that the universe is an ordered, rational system permeated by logos (reason). Studying nature therefore reveals the rational principles by which the cosmos operates, including divine providence and necessity. Ethical ideals such as “living in accordance with nature” depend directly on correct physical understanding; without physics, moral prescriptions would lack foundation. In this sense, natural science had clear ethical value, not merely speculative interest.

This position marks a clear disagreement with Socrates. Whereas Socrates treated cosmological inquiry as largely irrelevant or distracting from moral self-examination, the Stoics saw it as indispensable to moral progress. While they agreed with Socrates that ethics is the ultimate aim of philosophy, they rejected his dismissal of natural science and instead integrated it tightly into their ethical system.

In summary, the Stoics explicitly did not agree with Socrates on this point: they affirmed the study of natural science as a crucial and valuable component of philosophy, necessary for understanding both the cosmos and the proper conduct of human life.

Those two Joshua along with the material on Archimedes we need to come back to next week on the podcast

Here are a number of references we're incorporating into the current discussion of Socrates:

• Picture to yourself a little chamber into which no very brilliant light was admitted, with a crowd of people from all quarters, excited, carefully worked up, all aflutter with expectation. As they came in, they might naturally find a miracle in the development of that little crawling thing of a few days ago into this great, tame, human-looking serpent. Then they had to get on at once towards the exit, being pressed forward by the new arrivals before they could have a good look. An exit had been specially made just opposite the entrance, for all the world like the Macedonian device at Babylon when Alexander was ill. He was in extremis, you remember, and the crowd round the palace were eager to take their last look and give their last greeting. Our scoundrel’s exhibition, though, is said to have been given not once, but many times, especially for the benefit of any wealthy new-comers.
• And at this point, my dear Celsus, we may, if we will be candid, make some allowance for these Paphlagonians and Pontics. The poor uneducated ‘fat-heads’ might well be taken in when they handled the serpent—a privilege conceded to all who choose—and saw in that dim light its head with the mouth that opened and shut. It was an occasion for a Democritus, nay, for an Epicurus or a Metrodorus, perhaps, a man whose intelligence was steeled against such assaults by scepticism and insight, one who, if he could not detect the precise imposture, would at any rate have been perfectly certain that, though this escaped him, the whole thing was a lie and an impossibility.

What was Socrates’ position on whether it is important to study natural science and the nature of the universe?

Socrates did not consider the study of natural science (what the ancient Greeks called physis or inquiries into the nature of the cosmos, astronomy, meteorology, the elements, and the physical causes of phenomena) to be important or worthwhile for human life — at least not as a primary pursuit.He famously shifted the focus of philosophy away from these cosmological and physical speculations — which had dominated earlier thinkers like Thales, Anaximander, Anaximenes, Heraclitus, and Anaxagoras (the so-called pre-Socratics) — toward ethics, the examination of human affairs, virtue, justice, piety, and how one ought to live.Key Evidence from Primary Sources

• In Plato’s Apology (Socrates’ defense speech at his trial), he explicitly denies the popular accusation that he was a natural philosopher who investigated “things in the sky and below the earth.” He says he has no interest in or expertise in such matters and that the charge stems from a caricature (like Aristophanes’ comedy The Clouds, which mocks him as someone dangling in a basket measuring fleas and speculating about celestial phenomena). Socrates insists his real activity is questioning people about moral and ethical concepts in the marketplace.
• In Plato’s Phaedo (set on the day of Socrates’ death), he gives a more autobiographical account: As a young man, he was enthusiastic about natural philosophy and eagerly studied the works of pre-Socratic thinkers, hoping to discover the true causes of things (e.g., why things grow, why the earth is shaped as it is, or what makes the universe orderly). He became disillusioned when these materialistic explanations (e.g., Anaxagoras’ “Mind” as a cosmic force) failed to provide satisfying answers, especially about why things are ordered for the best or good. He abandoned this path as futile or misguided for human concerns and turned instead to examining human life, ethics, and the soul through dialectical questioning. He calls this his “second sailing” — a turn to logos (reasoned discourse) rather than direct empirical or physical investigation.
• In Xenophon’s Memorabilia (another student’s account of Socrates), Xenophon defends Socrates against similar charges by stating that he did not discuss “the nature of the universe” or speculate about the cosmos “as the others did.” Socrates reportedly argued that such inquiries were foolish: humans should focus on what is within their grasp (human affairs, ethics, practical wisdom), while leaving divine or cosmic matters to the gods (via divination if needed). He saw preoccupation with unreachable questions as neglect of more urgent human ones.

Why This Shift?Socrates believed true wisdom and the good life lie in self-knowledge (“know thyself”) and understanding moral concepts like virtue (which he often treated as a kind of knowledge). Speculating about the physical universe or its material causes did little to improve one’s character or make one a better person — it could even distract from ethical living or lead to impiety if it undermined traditional reverence for the divine order. He viewed the cosmos as intelligently ordered (with hints of divine design in Xenophon), but probing its mechanics mechanistically was not the path to virtue or happiness.In short, Socrates regarded the study of natural science and cosmology as largely unimportant — even potentially misguided — for the serious pursuit of wisdom and a good life. He prioritized the human realm (ethics, the soul, and moral improvement) over the natural one. This “Socratic turn” profoundly influenced later philosophy, marking a pivot from pre-Socratic naturalism to ethical and metaphysical inquiry in Plato and beyond.

Confirmed as the common view by Chatgpt:

What was Socrates’ position on whether it is important to study natural science and the nature of the universe?

In the ancient sources, Socrates is consistently portrayed as downplaying the importance of studying natural science and the physical structure of the universe, especially when compared with ethical inquiry.

According to Plato’s Apology, Socrates explicitly denies engaging in investigations “in the sky or below the earth,” distancing himself from the natural philosophers (physikoi) who speculated about cosmology, astronomy, and the ultimate constituents of matter. He presents this denial not merely as a defense against specific charges, but as a principled statement of his philosophical priorities. For Socrates, inquiry into nature was both uncertain and largely irrelevant to the central human task.

Socrates held that the most important questions concern how one ought to live: the nature of virtue, justice, piety, and the proper care of the soul. He believed that studying the cosmos does not reliably improve moral character and may even distract from self-knowledge. This stance is reinforced by later testimonies (such as those in Xenophon), which depict Socrates as skeptical that cosmological speculation yields practical or ethical benefit.

In short, Socrates did not regard the study of natural science or the nature of the universe as intrinsically valuable. He deliberately redirected philosophy away from cosmology and toward ethics, holding that understanding how to live well is far more important than understanding how the universe is structured.

More detail and specific reference to Epicurus from Claude:

Socrates famously argued against the importance of studying natural science and cosmology, representing a major shift in Greek philosophy from the natural philosophers (like Thales, Anaximander, and Democritus) who preceded him.

In Plato’s Apology, Socrates explicitly distances himself from natural philosophy when defending against charges. He denies investigating “things in the sky and below the earth,” stating he has no knowledge or expertise in such matters (Apology 19b-c).

In Plato’s Phaedo, Socrates describes his youthful interest in natural philosophy and his ultimate disappointment with it. He found that explanations based on material causes (like Anaxagoras’s system) failed to answer the questions that truly mattered to him - questions about purpose, goodness, and why things are as they should be (Phaedo 96a-99d).

Xenophon’s Memorabilia (IV.7) records Socrates actively discouraging students from studying astronomy, geometry, and other natural sciences beyond what’s practically necessary. He argued that such studies were:

• Endless and possibly futile
• A distraction from more important matters
• Less valuable than self-knowledge and ethical inquiry

Cicero famously credited Socrates with bringing “philosophy down from the heavens” and making it concerned with human life, ethics, and how one should live (Tusculan Disputations V.10).

Instead, Socrates insisted on the priority of self-knowledge (“Know thyself”) and ethical questions about virtue, justice, and the good life - what he considered truly important for human flourishing.

This represents a stark contrast with later philosophers like Epicurus, who considered natural science essential for removing fear and superstition.

Diogenes of Oinoanda:

Fr. 4

… [as is supposed by] some of the philosophers and especially the Socratics. They say that pursuing natural science and busying oneself with investigation of [celestial phenomena] is superfluous and unprofitable, and they do [not even] deign [to concern themselves with such matters.]
Fr. 5
[Others do not] explicitly [stigmatise] natural science as unnecessary, being ashamed to acknowledge [this], but use another means of discarding it. For, when they assert that things are inapprehensible, what else are they saying than that there is no need for us to pursue natural science? After all, who will choose to seek what he can never find?

Now Aristotle and those who hold the same Peripatetic views as Aristotle say that nothing is scientifically knowable, because things are continually in flux and, on account of the rapidity of the flux, evade our apprehension. We on the other hand acknowledge their flux, but not its being so rapid that the nature of each thing [is] at no time apprehensible by sense-perception. And indeed [in no way would the upholders of] the view under discussion have been able to say (and this is just what they do [maintain] that [at one time] this is [white] and this black, while [at another time] neither this is [white nor] that black, [if] they had not had [previous] knowledge of the nature of both white and black.

And from Epicurus:

Epicurus, Letter to Herodotus 37
Wherefore since the method I have described is valuable to all those who are accustomed to the investigation of nature, I who urge upon others the constant occupation in the investigation of nature, and find my own peace chiefly in a life so occupied, have composed for you another epitome on these lines, summing up the first principles of the whole doctrine. (Bailey)

Epicurus, Principal Doctrine 11
Were we not upset by the worries that celestial phenomena and death might matter to us, and also by failure to appreciate the limits of pains and desires, we would have no need for natural philosophy. (L&S-THP)

Epicurus, Principal Doctrine 12
There is no way to dispel the fear about matters of supreme importance, for someone who does not know what the nature of the universe is but retains some of the fears based on mythology. Hence without natural philosophy there is no way of securing the purity of our pleasures. (L&S-THP)

Epicurus, Principal Doctrine 13
There is no benefit in creating security with respect to men while retaining worries about things up above, things beneath the earth, and generally things in the infinite. (L&S-THP)

Epicurus, Vatican Saying 29
I would rather speak with the frankness of a natural philosopher, and reveal the things which are expedient to all mankind, even if no one is going to understand me, than assent to the received opinions and reap the adulation lavishly bestowed by the multitude. (L&S-THP)

Epicurus, Vatican Saying 45
Natural philosophy does not make people boastful and loud-mouthed, nor flaunters of culture, the thing so hotly competed for among the multitude, but modest and self-sufficient, and proud at their own goods, not at those of their circumstances. (L&S-THP)

Lucretius 1.62-79
(1) When human life lay foul to see and groveling upon the ground, crushed by the weight of Religion, who displayed her head from the regions of heaven, lowering over mortals with horrible aspect, (2) a man of Greece dared first to raise his mortal eyes against her, first to make a stand against her; for neither fables of the gods could quell him, nor thunderbolts, nor heaven with menacing roar, but all the more they goaded the eager courage of his soul to long to be the first to burst through the close-set bolts of nature’s gates. (3) Therefore his vigorous mind won through, and he passed on far beyond the fiery walls of the world, and in mind and spirit traversed the boundless universe; (4) whence returning victorious he reports to us what can arise, what cannot, and by what principle each thing has its powers limited and its deep-set boundary stone. (5) Therefore Religion is now in turn cast down and trampled underfoot, while we by the victory are exalted high as heaven. (L&S-THP)

Episode 320 of the Lucretius Today Podcast is now available. This week our episode is entitled: "Is The Good of A Sheep The Same As The Good of A Man?"

Happy Birthday to mlinssen! Learn more about mlinssen and say happy birthday on mlinssen's timeline: mlinssen

In this episode one of the issues discussed was Cicero ridiculing Epicurus for taking a position that Cicero characterizes as saying that the good of a sheep and the good of a man are the same. That line of argument appears in a number of places that we did not list in the episode. Here are more occasions:

1 - Cicero, De Fin. 2.109

Quare aliud aliquod,Torquate, hominis summum bonum reperiendum est, voluptatem bestiis
concedamus.

Therefore,Torquatus, some other supreme good must be found for a human being. Let
us leave pleasure to the nonhuman animals.

2 - Cicero, De Fin. 2.111

Nec tamen ullo modo summum pecudis bonum et hominis idem mihi videri potest.

I cannot in any way think that humans and livestock have the same supreme good.

3 - Aristotle, EN I .5 I 095bI9-20 (Cf. Heraclitus frr. 4 and 29, and Plato, flej?_. 586a-b)

4 - Cicero, De Fin. 2.33

Bestiarum vero nullum iudidum puto. Quamvis enim depravatae non sint, pravae tamen esse
possunt Ut bacillum aliud est inflexum et incurvatum de industria, dud ito natum, sic ferarum
natura non est No quidem depravata mak disciplina, sed natura sua.

In truth, I think nothing of the judgment of nonhuman animals. For although they may not
have been corrupted, still they can be corrupt. Just as one stick is bent and distorted
intentionally and another has grown that way, so the nature of wild animals is not that
way because it is corrupted by bad training, but by its own nature.

5 - Cicero, De fin. 2.33-34

Nec vero ui voluptatem expetat natura movet infantem, sed tantum ut se ipse diligat, ut
integrum se salvumque velit Omne enim animal, simul et orwm est, et se ipsum et omnes
portes suas diligit duasque quae maximae suns in primis amplectltur, animum et corpus, deinde
utriusque parses. Nam sunt et in anima praedpua quaedam et in corpore, quae cum leviter
agnovit, turn discernere indpit, ut ea quae prima data sint natura oppetas ospemeturque
contraria. In his primis naturolibus voluptas insit necne, magna quaestio est; nihil vero putare
esse praeter voluptatem, non membra, non sensus, non ingeni motum, non integritotem corporis,
non valetudinem [corporis],summae mihi videtur inscitioe.

In truth, nature moves the newborn not to seek pleasure but simply to love itself and to
wish to keep itself safe and sound. For every animal, as soon as it is born, loves both itself
and all its parts, and it embraces above all its two greatest things, mind and body, and then the parts of each. For both in mind and in body there are certain preferred things
which the animal has slightly recognized, and then begins to distinguish, with the result
that it seeks these things that are first given by nature and it spurns their contraries.
Whether pleasure is among the first natural things or not is not a difficult question. But
it seems to me the height of folly to think that it consists of nothing in truth except
pleasure, no limbs, no senses, no mental activity, no bodily soundness, no health.

6 - Cicero, Fin. 2.109-1 I0
(Quare aliud aliquod,Torquate,hominis summum bonum reperiendum est] voluptatem bestiis
concedamus, quibus vos de summo bono testibus uti soletis. Quid si etiam bestiae multa faciunt
duce sua quaeque natura, partim indulgenter vel cum labore, ut in gignendo, in educando
perfacile appareat aliud quidam Hs propositum, non voluptatem? Partim cursu et peragratione
laetantur; congregatione aline coetum quodam modo civitatis imitantur; videmus in quodam
volucrium genere nonnula indicia pietatis, cognitionem, memoriam, in multis etiam desideria
videmus. Ergo in bestiis erunt secreta a voluptate humanarum quaedam simulacra virtutum, in
ipsis hominibus virtus nisi voluptatis causa nulla erit?

Let us leave pleasure to the animals, whose testimony about the supreme good you all
customarily use. But what if even nonhuman animals do many things with their nature as
their guide, which make it clearly apparent that they have aim other than pleasure? Some
do things with kindness, even with difficulty, in giving birth to and rearing their young.
Some love to run free and roam about. Some, because they are gregarious, imitate the
gathering of a civil society in a way. In a certain class of birds we see signs of loyalty, and
we see recognition and memory; in many we even see grief. Will there therefore be
semblances of human virtues in nonhuman animals independently of pleasure, while in
humans themselves there will be no virtue that is not for the sake of pleasure?

7 - Cicero, Fin. 2.40

Hi non viderunt, ut ad cursum equum, ad arandum bovem, ad indagandum canem, sic hominem ad duos res, ut ait Aristoteles, ad intellegendum et <ad> agendum esse natum quasi mortalem
deum, controque ut tardam aliquam et languidam pecudem ad pastum et ad procreandi
voluptatem hoc divinum animal ortum esse voluerunt, quo nihil mihi videtur absurdius.

They [viz.,Aristippus and the Cyrenaics] did not see that just as a horse is born for running, an ox for ploughing, and a dog for hunting, so a human is born for two things, as Aristotle says, for thinking and for acting, as if a mortal god.They, by contrast, wanted this divine animal to be born for grazing and the pleasure of procreating, like a slow and lazy sheep. Nothing seems to me more absurd than this.

8 - Cicero, Fin. 2.45-47

Homines enim, etsi aliis muhis, tam en hoc uno plurimum a bestiis differunt quod rationem
habent a natura datam mentemque acrem et vigentem celerrimeque multa simul agitantem...

Even if humans differ from nonhuman animals in many other ways, they differ most in
this one way, that they are endowed by nature with reason and with a sharp and
vigorous intellect that does many things simultaneously and very swiftly...

I will be working to improve the text of the text-to-speech version of Bailey being used to generate the one based on Joshua's voice.

I am going to try to learn GIT so I can keep better track of changes and more easily accept suggestions. Given the current engine we are working with it's sometimes necessary to cut super-long sentences into multiple shorter ones, or slightly modify wording in way that the engine can handle without spazzing out. If you'd like to see that text and/or participate with improving the audio, the raw file is at this CODEBERG location:

Cookie monster!

If you know GIT feel free to suggest updates. If you don't know git, you can (1) click the "view source" button " < >" and it will show you the line numbers that need editing and then (2) submit changes either here in this thread or to me by private conversation.

I'll add other links as I find them but we need a media (audio) version of the Life of Epicurus, so this will start that process.

First, I have two versions of Book 10. The first and latest is Cyril Bailey translation. This is a first draft and I am going to work on improving it and will update this link.

(Status as of 2/9/26 15:45 The voice is better but there are still glitches in output.)

And here is an older version in a female voice which is less advanced but still very listenable. i need to check but i think this is the Hicks version:

In addition to the reference in Academic Questions, we have these additional citations to consider in contrasting Cicero's praise of Socrates to the Epicurean criticism of Socrates. The Epicurean criticism divides into at least two categories (1) Socrates' abandonment of the study of natural science, with all the many implications of that decision, and - related to that - (2) Socrates' assertion that the only thing he knew was that he knew nothing

• Quote

  Nor was Pythagoras the inventor only of the name, but he enlarged also the thing itself, and, when he came into Italy after this conversation at Phlius, he adorned that Greece, which is called Great Greece, both privately and publicly, with the most excellent institutions and arts; but of his school and system, I shall, perhaps, find another opportunity to speak. But numbers and motions, and the beginning and end of all things, were the subjects of the ancient philosophy down to Socrates, who was a pupil of Archelaus, who had been the disciple of Anaxagoras. These made diligent inquiry into the magnitude of the stars, their distances, courses, and all that relates to the heavens. But Socrates was the first who brought down philosophy from the heavens, placed it in cities, introduced it into families, and obliged it to examine into life and morals, and good and evil. And his different methods of discussing questions, together with the variety of his topics, and the greatness of his abilities, being immortalized by the memory and writings of Plato, gave rise to many sects of philosophers of different sentiments: of all which I have principally adhered to that one which, in my opinion, Socrates himself followed; and argue so as to conceal my own opinion, while I deliver others from their errors, and so discover what has the greatest appearance of probability in every question. And the custom Carneades adopted with great copiousness and acuteness, and I myself have often given in to it on many occasions elsewhere, and in this manner, too, I disputed lately, in my Tusculan villa; indeed I have sent you a book of the four former days' discussions; but the fifth day, when we had seated ourselves as before, what we were to dispute on was proposed thus:—

  --Cicero, Tusculan Disputations, Book 5, paragraph 4

  
  
  Thats what I would contrast with the statements of Epicurus emphasizing natural philosophy as essential, and then Diogenes of Oinoanda
  
  Fr. 4
  
  ... [as is supposed by] some of the philosophers and especially the Socratics. They say that pursuing natural science and busying oneself with investigation of [celestial phenomena] is superfluous and unprofitable, and they do [not even] deign [to concern themselves with such matters.]

  Fr. 5
  Others do not] explicitly [stigmatise] natural science as unnecessary, being ashamed to acknowledge [this], but use another means of discarding it. For, when they assert that things are inapprehensible, what else are they saying than that there is no need for us to pursue natural science? After all, who will choose to seek what he can never find?
  Now Aristotle and those who hold the same Peripatetic views as Aristotle say that nothing is scientifically knowable, because things are continually in flux and, on account of the rapidity of the flux, evade our apprehension. We on the other hand acknowledge their flux, but not its being so rapid that the nature of each thing [is] at no time apprehensible by sense-perception. And indeed [in no way would the upholders of] the view under discussion have been able to say (and this is just what they do [maintain] that [at one time] this is [white] and this black, while [at another time] neither this is [white nor] that black, [if] they had not had [previous] knowledge of the nature of both white and black.

  And the so-called [ephectic philosophers], of whom Lacydes [of Cyrene]...
