Another thing I'd add is that the cup analogy is just that - an "analogy" - as would be the ideal of all experience being pleasure. I think there's a tendency for us all to be thinking in terms of "explain to me exactly what I must do to enter the kingdom of heaven." In other words, give me the exact prescription for paradise, and I'll follow exactly those steps so that I - and everyone else who drinks the medicine - will experience exactly the same thing. With the idea being that there is some precise experience - setting foot in heaven or experiencing exactly the same euphoria of a magic potion - that is being talked about.

But life is not like that. Everyone has their own circumstances, and everyone has their own preferences in pleasures, and so the goal of everyone is not the same in exact terms -- only in abstract terms. And in abstract terms, it's very simple (and helpful, as a clear statement of a goal) to identify that what you would really like to have is "complete" pleasure with no mixture of pain.

But in our rush to think that there is a magic pill that everyone can experience the same way, we forget those differences, and we try to force "absence of pain" into a particular experience that we can climb into like a 1957 Chevy.

And the trouble is compounded because what is really in issue is not some abstract definition of a goal like a "kingdom of heaven." What really is the truth is that we don't live forever, our souls are not magical or divine, there's no life after death, no "god" to tell us what to do, and we have to ourselves use our time as we deem best, just like any other dolphin or horse or cat or dog or any other living thing must do. Only humans have the disposition to be lulled into complacency by thinking that there is some afterlife that we can look forward to as our reward, and thereby trade in our time in the hear and now for a promise of something "better" later.

I don't believe Epicurus saw "absence of pain" as something equivalent to a kingdom of heaven for which we trade the pleasures that are available to us while we are alive. I think he saw that life is a real-life here-and-now experience in which the best we can do is to organize our activities so that the time that we are as happy as possible during the time that we have.

This is the opposite of monasticism or passivity or the kind of intellectualism that results in going round and round and debating how many angels can dance on the head of a pin. It's a very practical call to action to use your life as productively as you can during the time that you have, with "productivity" defined not in terms of purely bodily pleasure or purely mental pleasure but in terms of whatever combination of both nature impresses on you as the "happiest" way to spend your time. To paraphrase Torquatus, the person who runs from all pain and mental and bodily activity and who cannot foresee the disaster to which that kind of life will lead is worthy of contempt, not a chair in philosophy. Likewise in Jefferson's advice to william short, we need to "brace ourselves up" and get on with life, because the kind of soft indulgence in indolence that comes from what some people want to see as "absence of pain" is the furthest thing possible from what Epicurus actually taught.

This forum is the place for students of Epicurus to coordinate their studies and work together to promote the philosophy of Epicurus. Please remember that all posting here is subject to our Community Standards / Rules of the Forum our Not Neo-Epicurean, But Epicurean and our Posting Policy statements and associated posts.

Please understand that the leaders of this forum are well aware that many fans of Epicurus may have sincerely-held views of what Epicurus taught that are incompatible with the purposes and standards of this forum. This forum is dedicated exclusively to the study and support of people who are committed to classical Epicurean views. As a result, this forum is not for people who seek to mix and match some Epicurean views with positions that are inherently inconsistent with the core teachings of Epicurus.

All of us who are here have arrived at our respect for Epicurus after long journeys through other philosophies, and we do not demand of others what we were not able to do ourselves. Epicurean philosophy is very different from other viewpoints, and it takes time to understand how deep those differences really are. That's why we have membership levels here at the forum which allow for new participants to discuss and develop their own learning, but it's also why we have standards that will lead in some cases to arguments being limited, and even participants being removed, when the purposes of the community require it. Epicurean philosophy is not inherently democratic, or committed to unlimited free speech, or devoted to any other form of organization other than the pursuit by our community of happy living through the principles of Epicurean philosophy.

One way you can be most assured of your time here being productive is to tell us a little about yourself and your background in reading Epicurean texts. It would also be helpful if you could tell us how you found this forum, and any particular areas of interest that you have which would help us make sure that your questions and thoughts are addressed.

We have found over the years that there are a number of key texts and references which most all serious students of Epicurus will want to read and evaluate for themselves. Those include the following.

"Epicurus and His Philosophy" by Norman DeWitt

The Biography of Epicurus by Diogenes Laertius. This includes the surviving letters of Epicurus, including those to Herodotus, Pythocles, and Menoeceus.

"On The Nature of Things" - by Lucretius (a poetic abridgement of Epicurus' "On Nature"

"Epicurus on Pleasure" - By Boris Nikolsky

The chapters on Epicurus in Gosling and Taylor's "The Greeks On Pleasure."

Philodemus "On Methods of Inference" (De Lacy version, including his appendix on relationship of Epicurean canon to Aristotle and other Greeks)

"The Greeks on Pleasure" -Gosling & Taylor Sections on Epicurus, especially the section on katastematic and kinetic pleasure which explains why ultimately this distinction was not of great significance to Epicurus.

It is by no means essential or required that you have read these texts before participating in the forum, but your understanding of Epicurus will be much enhanced the more of these you have read. Feel free to join in on one or more of our conversation threads under various topics found throughout the forum, where you can to ask questions or to add in any of your insights as you study the Epicurean philosophy.

And time has also indicated to us that if you can find the time to read one book which will best explain classical Epicurean philosophy, as opposed to most modern "eclectic" interpretations of Epicurus, that book is Norman DeWitt's Epicurus And His Philosophy.

Patrikios check here: RE: Prolepsis / Anticipations As Epicurus' Answer to the MENO Problem

I hope Bryan won't mind but I think we need to add here a comment he just made on his wall:

Quote from From Bryan's Wall

What are now considered to be areas of empty space are really full of tiny, undetectable particles. We cannot see or measure them because they pass through us -- and through our instruments -- with almost no interference. “Gravity,” in the sense of a force acting at a distance without contact, does not exist. What we call “gravity” is really the result of how larger objects interact with the wakes and currents they create in the medium of these smaller particles.

Objects move in the direction they are already moving, without any loss of speed, and deviating only slightly and rarely -- unless they make contact with something else. To believe (as those who follow Einstein do) in forces beyond the force of touch -- is to give in to magical thinking.

To which I posted this reply:

This is a topic I've been thinking a lot about as a result of going through Matthew Stewart's book. Apparently there were several major failures of follow-through in the years after the Epicurean period.

Simply talking about "pleasure" and rejecting some (but not all) aspects of supernatural religion doesn't go nearly far enough if you're going to turn around and talk like the Deists did, and you:

(1) claim agnosticism about whether there is life after death, or even hopefulness that there is, and

(2) accept the possibility that particle motion is imposed on them by some force outside the particles themselves.

(3) talk about Nature or "everything" as a "God" (pantheism) without being clear that when you use the word god you are excluding supernatural action and design.

All if these three are really pretty simple to understand, but the "motion caused by unknown outside forces" that you're talking about in this wall post is probably the easiest of all to see how important it is.

And that surely helps explain why we have a section on magnetism in Lucretius (book six around line 1000) explaining that issue too in terms of flows of particles, not in terms of any mysterious outside force.

As to examining the issue of "weight" more closely, Joshua has pointed out in Lucretius Today 275 that "gravitas" seems to be the word used by Lucretius for "weight," and Don pointed out this as to the Greek:

Quote from Don

Joshua asked about the Greek word for "weight" in the characteristics of the atom: βάρος (baros). From which we get words like barometric, barometer "instrument for measuring the weight or pressure of the atmosphere," barophobia "an abnormal fear of gravity."

Here is another section from Lucretius where "gravitas" is not the word used. Given that there is never in any of these statements that there is "something else" pulling the atoms "down," I presume a good case can be made that regardless of the terminology, Epicurus was clear that this force of "weight" was something within the atoms themselves, not a force that is separate and apart from the atoms themselves. That is, other atoms and groups of atoms arguably could exert a pulling motion, but there is no extra-atomic force that operates on the atoms. This is very important for closing the door to the argument that some people like to make that this "force outside the atoms" is "god."

5-181

Whence again was first implanted in the gods a pattern for begetting things in general as well as the preconception of what men are, so that they knew and saw in mind what they wanted to make? And in what way was the power of first-beginnings ever ascertained, and what they could effect by a change in their mutual arrangements, unless nature herself gave the model for making things? For in such wise the first-beginnings of things many in number in many ways impelled by blows for infinite ages back and kept in motion by their own weights have been wont to be carried along and to unite in all manner of ways and thoroughly test every kind of production possible by their mutual combinations; that it is not strange if they have also fallen into arrangements and have come into courses like to those out of which this sum of things is now carried on by constant renewing.

5-181

Exemplum porro gignundis rebus et ipsa
notities hominum divis unde insita primum est,
quid vellent facere ut scirent animoque viderent,
quove modost umquam vis cognita principiorum
quidque inter sese permutato ordine possent.
si non ipsa dedit speciem natura creandi?
namque ita multa modis multis primordia rerum
ex infinito iam tempore percita plagis
ponderibusque suis consuerunt concita ferri
omnimodisque coire atque omnia pertemptare,
quae cumque inter se possint congressa creare,
ut non sit mirum, si in talis disposituras
deciderunt quoque et in talis venere meatus,
qualibus haec rerum geritur nunc summa novando.

Selecting out something of particular interest in that large wall of text, I'd like to verify if THIS is accurate, as it is an explicit criticism of Epicurean views of the universe:

1. On Materialism in De immenso et innumerabilibus (On the Immense and Innumerable, 1591):
   • Context: In this Latin work, Bruno elaborates his cosmology, incorporating atomistic ideas but infusing them with vitalism. He discusses the composition of the universe, referencing ancient thinkers.

   • Quote (Book 1, Chapter 6, translated by J. Lewis McIntyre):

     “Some, like the Epicureans, have thought the universe to be composed of atoms and void alone, but they err in denying the universal soul that binds and vivifies all.”

   • Analysis: This is one of the rare instances where Bruno explicitly references “Epicureans.” He acknowledges their atomistic framework but criticizes it for “denying the universal soul,” a core tenet of his philosophy. For Bruno, atoms aren’t just inert particles (as in Epicurus’ system) but are imbued with a divine, animating force. This critique directly challenges Epicurean materialism, which avoids any spiritual or teleological principle, seeing the universe as a random interplay of atoms. Bruno’s use of “err” signals a clear disagreement with Epicurus’ reductionist view.
   • Criticism?: Explicit and direct. This is the strongest evidence of Bruno criticizing Epicurean thought, though it’s still framed as a philosophical correction rather than a personal attack on Epicurus.

Looks like this work is here:

Giordano Bruno

www.gutenberg.org

No - it's here, but in Latin.....

There are many good things to be said about Giordano Bruno, while at the same time keeping clear about philosophical differences, especially as to "pantheism."

Here's what Grok says about whether Bruno was an Epicurean or a Pantheist:

Giordano Bruno (1548–1600) is a fascinating figure to pin down philosophically, as his ideas don’t neatly fit into either Pantheism or Epicureanism in their purest forms. However, based on his writings and worldview, Bruno is more accurately described as a pantheist with some sympathies toward ideas that resonate with Epicureanism, though he wasn’t a strict follower of Epicurus. Let’s break it down by examining his positions in relation to both philosophies:

Bruno and Pantheism

Pantheism equates God with the universe, viewing all existence as divine without a separate, personal deity. Bruno’s philosophy aligns closely with this:

• Divine Immanence: In works like De l’infinito, universo e mondi (On the Infinite Universe and Worlds) and De la causa, principio e uno (On Cause, Principle, and Unity), Bruno argues that God is infinite, immanent, and identical with the universe. He writes, “The divine essence is all in all,” suggesting that divinity permeates every part of reality, from stars to atoms.
• Infinite Universe: Bruno rejected the medieval geocentric model, proposing an infinite cosmos with countless worlds (stars and planets), all animated by a single divine substance. This vision of a boundless, unified reality is pantheistic, as it sees no separation between God and nature.
• Monism: Bruno’s metaphysics leans toward a monistic view where matter and spirit are expressions of one infinite substance, a hallmark of pantheism (similar to Spinoza, who came later). He saw the universe as alive and divine, with no external creator.
• Rejection of Traditional Theism: Bruno dismissed the idea of a personal, transcendent God who intervenes in human affairs, aligning with pantheism’s impersonal divinity.

Bruno’s pantheism was radical for his time, blending mystical, Neoplatonic, and naturalistic elements. His reverence for the universe as divine led to accusations of heresy, contributing to his execution by the Inquisition in 1600.

Bruno and Epicureanism

Epicureanism, rooted in Epicurus’ teachings, emphasizes materialist atomism, distant gods, and a hedonistic ethic of achieving pleasure through tranquility. Bruno shares some affinities but diverges significantly:

• Materialism and Atomism:
  • Similarity: Bruno was influenced by Lucretius’ De Rerum Natura, a key Epicurean text, and adopted a form of atomism, viewing the universe as composed of minimal units. Like Epicurus, he saw matter as eternal and uncreated.
  • Difference: Bruno’s atomism wasn’t purely mechanistic like Epicurus’. He infused his atoms with a vital, spiritual quality, calling them “monads” or animated by a divine principle, which clashes with Epicurean materialism’s strict physicalism. For Epicurus, atoms and void are all that exist; for Bruno, matter is inseparable from a divine, living essence.
• View of Gods:
  • Similarity: Bruno, like Epicurus, rejected anthropomorphic deities who meddle in human life. He criticized the Church’s dogmatic view of God as a separate, judgmental being.
  • Difference: Epicurus posited gods as distant, atomic beings living in bliss, irrelevant to the universe’s workings. Bruno went further, denying separate gods entirely and identifying divinity with the infinite universe itself—a pantheistic stance far from Epicurean theology.
• Ethics and Purpose:
  • Similarity: Bruno valued intellectual freedom and a life aligned with nature, which could echo Epicurean calls for rational living and avoiding superstition. His emphasis on philosophical inquiry might resemble Epicurus’ focus on mental tranquility through understanding.
  • Difference: Epicureanism’s ethics center on achieving ataraxia (tranquility) and aponia (absence of pain) through simple pleasures, moderation, and friendship. Bruno’s writings, like Spaccio de la bestia trionfante (The Expulsion of the Triumphant Beast), focus more on cosmic contemplation, heroic enthusiasm, and transforming human understanding of the universe. He doesn’t advocate a hedonistic ethic or prioritize personal pleasure in the Epicurean sense.
• Cosmology:
  • Similarity: Both Bruno and Epicurus envisioned an infinite universe, a bold departure from Aristotelian finite cosmology.
  • Difference: Epicurus’ infinity was a mechanistic backdrop for atomistic interactions, with no divine quality. Bruno’s infinite universe was a living, divine whole, imbued with purpose and intelligence, aligning more with pantheism’s holistic view.

Why Pantheist Over Epicurean?

While Bruno drew inspiration from Epicurean ideas—especially Lucretius’ atomism and rejection of religious dogma—his philosophy is fundamentally pantheistic because of his core belief that the universe itself is God, animated by a divine unity. Epicureanism’s strict materialism, indifferent gods, and hedonistic ethics don’t capture Bruno’s mystical and metaphysical vision. His universe is not a random dance of atoms but a purposeful, infinite expression of divinity, closer to pantheistic thinkers like Spinoza (though Bruno’s style is less systematic).

Bruno’s engagement with Epicureanism was selective, using its naturalism to challenge Church doctrine while embedding those ideas in a broader, spiritual framework. For example, in De l’infinito, he writes of the universe as “one, infinite, immobile… all is one,” reflecting a pantheistic unity rather than Epicurean atomistic pluralism.

Was There Any “Pure” Epicureanism in Bruno?

To address your earlier interest in “pure” Epicureanism: Bruno doesn’t qualify. His atomism and cosmology borrow from Epicurus, but his infusion of divine vitality and rejection of Epicurean ethics (pleasure as the goal) make his philosophy eclectic, not purely Epicurean. If you’re hunting for someone who claimed a strict Epicurean identity, Bruno falls short, as his pantheistic vision dominates.

Final Verdict

Giordano Bruno was a pantheist, not an Epicurean, though he incorporated Epicurean elements like atomism and anti-dogmatism into his broader, divine-infused cosmology. His view of an infinite, divine universe sets him apart from Epicurus’ materialist, pleasure-focused philosophy.

-------------------------

Here's Chatgpt:

Giordano Bruno (1548–1600) is best classified as a pantheist, not an Epicurean, although he was influenced by atomistic and materialist currents that had some overlap with Epicurean thought.

Reasons Bruno is a Pantheist:

1. Identification of God with Nature:
   Bruno held that God and the universe are one. He wrote that the divine is present in all things and that the universe is infinite and eternal. This belief aligns directly with pantheism, especially in the tradition later associated with Spinoza.
2. Infinite Worlds and Unity:
   Bruno proposed an infinite cosmos with innumerable worlds, each imbued with divine presence. This vision stems from Neoplatonic and Hermetic influences, combined with a radical reinterpretation of ancient cosmologies. For Bruno, nature was a living expression of the divine.
3. Spiritualized Matter:
   While he accepted the existence of matter, he rejected the purely mechanical and soul-less view held by Epicureans. Bruno imbued matter with spirit or soul, asserting a kind of universal animation or life-force.
4. Rejection of Epicurean Atheism and Hedonism:
   Bruno was critical of Epicurean ethics, particularly their hedonism and denial of divine providence. He considered Epicurus overly mechanistic and spiritually barren. His own writings emphasized spiritual and mystical unity rather than personal pleasure.

However, Bruno and Epicurus Had Some Common Ground:

• Atomism and Anti-Aristotelianism:
  Bruno admired Lucretius, the Roman Epicurean poet, for his eloquence and for promoting an infinite universe composed of particles. Bruno used such ideas to support his break from Aristotelian cosmology.
• Cosmic Pluralism:
  Both Epicureanism and Bruno’s cosmology featured multiple worlds, but while Epicurus envisioned them as material and indifferent, Bruno infused them with divine intelligence.

Conclusion:

Giordano Bruno was not an Epicurean in the philosophical sense. His metaphysics was pantheistic, mystical, and deeply spiritual, whereas Epicureanism is naturalistic, atheistic in practice, and focused on personal tranquility through rational analysis. Despite sharing a belief in an infinite cosmos, their ethical, metaphysical, and theological outlooks were fundamentally different.

---------------------------

However- - when pushed for documentation, Chatgpt backtracks:

Upon reviewing the available sources, it appears that there is no direct evidence of Giordano Bruno explicitly criticizing Epicurean ethics, particularly their hedonism or denial of divine providence. While Bruno engaged with Epicurean ideas, especially in cosmology, his writings do not contain specific condemnations of Epicurean ethical principles.

Bruno's philosophical framework was deeply rooted in Neoplatonism and Hermeticism, leading him to view the universe as a living, divine organism. He posited the existence of a Universal Soul permeating all matter, suggesting that even inanimate objects possessed a degree of life. This perspective starkly contrasts with Epicureanism, which denies any form of divine immanence or universal consciousness. However, this divergence does not equate to a direct critique of Epicurean ethics.

In summary, while Bruno's metaphysical views differ significantly from those of Epicureanism, there is no substantial evidence to support the claim that he was overtly critical of Epicurean ethical doctrines. Therefore, any assertion of such criticism would require further substantiation from primary sources.

-----------------------------------------------

When pushed further, GROK says this:

Did Giordano Bruno specifically criticize Epicurus? If so give me quotes

Giordano Bruno (1548–1600) did not extensively or explicitly criticize Epicurus in a direct, personal manner in his surviving works, but he did engage with Epicurean ideas, particularly through his reading of Lucretius’ De Rerum Natura, the primary source for Epicureanism in the Renaissance. Bruno’s relationship with Epicureanism is complex: he admired aspects of it, such as its atomism and rejection of religious superstition, but he diverged from its strict materialism and theological positions, favoring a pantheistic worldview. Where Bruno does critique Epicurean ideas, it’s often indirect, focusing on refining or correcting what he saw as limitations in their metaphysics or cosmology, rather than attacking Epicurus himself.

Finding specific quotes where Bruno directly names and criticizes Epicurus is challenging because Bruno’s style is eclectic, and he tends to synthesize rather than single out thinkers for condemnation. However, I can point to instances where he implicitly critiques Epicurean principles, particularly in his cosmological and metaphysical works, and explain how they relate to Epicurus. Below, I’ll provide relevant passages (translated from Italian or Latin where necessary) from Bruno’s key texts and analyze their connection to Epicureanism. If Bruno doesn’t name Epicurus explicitly in a critical way, I’ll also clarify why and offer context.

Bruno’s Engagement with Epicureanism

Bruno was influenced by Lucretius and, through him, Epicurus, particularly for their atomistic view of the universe and rejection of a providential deity. However, Bruno’s pantheistic belief in an infinite, divine universe animated by a vital principle clashed with Epicureanism’s mechanistic materialism and its view of gods as distant, non-interventionist beings. Where Bruno might seem to “criticize” Epicurus, it’s often a matter of reinterpreting or expanding Epicurean concepts to align with his own monistic vision.

Here are the closest instances where Bruno’s writings touch on Epicurean ideas, with analysis of whether they constitute criticism:

1. On Epicurean Atomism in De l’infinito, universo e mondi (On the Infinite Universe and Worlds, 1584):
   • Context: Bruno praises the idea of an infinite universe, which aligns with Epicurus’ cosmology (Epicurus posited an infinite universe with countless worlds). However, he critiques materialist atomism for lacking a unifying divine principle.

   • Quote (from Dialogue 1, translated by Frances Yates):

     “The universe is one, infinite, immobile… It is not composed of parts that are finite in number, as some have said, nor is it a mere aggregation of atoms, but rather it is a whole, animated by a single spirit.”

   • Analysis: Here, Bruno implicitly critiques Epicurean atomism, which sees the universe as an infinite aggregation of atoms moving in a void. The phrase “not… a mere aggregation of atoms” likely references Lucretius’ (and thus Epicurus’) view, which Bruno finds reductive because it lacks his pantheistic notion of a “single spirit” animating all things. This isn’t a direct attack on Epicurus by name but a philosophical correction of materialism, suggesting it fails to account for the universe’s divine unity.
   • Criticism?: Indirect. Bruno builds on Epicurean infinity but rejects its mechanistic framework, implying Epicurus’ model is incomplete.
2. On the Nature of Divinity in De la causa, principio e uno (On Cause, Principle, and Unity, 1584):
   • Context: Bruno discusses the divine as immanent in all things, contrasting with views of gods as separate entities. Epicureanism posits gods as material, blissful beings who exist apart from the world and don’t interfere.

   • Quote (from Dialogue 4, translated by Sidney Greenberg):

     “Those who place the divine outside the world, or imagine gods in some remote interstices, err gravely, for the divine is not absent but present in all things, the cause and principle of nature itself.”

   • Analysis: This passage critiques theological positions that separate divinity from the universe, including Epicureanism’s view of gods living in the intermundia (spaces between worlds), uninvolved with creation. Epicurus isn’t named, but his concept of detached gods is implicitly targeted as “erring gravely” because it contradicts Bruno’s pantheistic unity, where God is “present in all things.” Bruno sees Epicurean gods as a misstep, failing to recognize divinity as the universe’s essence.
   • Criticism?: Implicit but clear. Bruno rejects Epicurus’ theology as incompatible with his monism, though he doesn’t single him out directly.
3. On Materialism in De immenso et innumerabilibus (On the Immense and Innumerable, 1591):
   • Context: In this Latin work, Bruno elaborates his cosmology, incorporating atomistic ideas but infusing them with vitalism. He discusses the composition of the universe, referencing ancient thinkers.

   • Quote (Book 1, Chapter 6, translated by J. Lewis McIntyre):

     “Some, like the Epicureans, have thought the universe to be composed of atoms and void alone, but they err in denying the universal soul that binds and vivifies all.”

   • Analysis: This is one of the rare instances where Bruno explicitly references “Epicureans.” He acknowledges their atomistic framework but criticizes it for “denying the universal soul,” a core tenet of his philosophy. For Bruno, atoms aren’t just inert particles (as in Epicurus’ system) but are imbued with a divine, animating force. This critique directly challenges Epicurean materialism, which avoids any spiritual or teleological principle, seeing the universe as a random interplay of atoms. Bruno’s use of “err” signals a clear disagreement with Epicurus’ reductionist view.
   • Criticism?: Explicit and direct. This is the strongest evidence of Bruno criticizing Epicurean thought, though it’s still framed as a philosophical correction rather than a personal attack on Epicurus.

Why Limited Direct Criticism?

Bruno’s lack of frequent, explicit attacks on Epicurus can be explained by several factors:

• Renaissance Context: Epicurus was a controversial figure in the 16th century, often vilified by the Church as an atheist. Bruno, already under scrutiny for heresy, may have avoided direct criticism to sidestep further accusations, especially since he admired aspects of Epicureanism (e.g., its anti-superstition stance).
• Synthetic Approach: Bruno’s philosophy blends ideas from many sources—Plato, Neoplatonism, Lucretius, Copernicus—rather than fixating on refuting one thinker. He engages Epicurus through Lucretius, adopting what fits (atomism, infinite worlds) and reframing what doesn’t (materialism, gods).
• Focus on Broader Targets: Bruno’s sharper critiques target Aristotelian cosmology, Ptolemaic geocentrism, and Church dogma, which he saw as greater obstacles to his infinite, divine universe.

Did Bruno Criticize Epicurus Specifically?

Yes, but sparingly and indirectly in most cases. The clearest instance is in De immenso, where he names “Epicureans” and faults their denial of a universal soul. Elsewhere, his critiques are woven into broader arguments against materialist or separatist views of divinity, implicitly challenging Epicurean principles without always naming Epicurus. Bruno respects Epicurus’ naturalism but finds his system too limited for his pantheistic vision.

Reflection on Your Interest

Since you’re curious about “pure” Epicureanism and Bruno’s stance, it’s worth noting that Bruno doesn’t align with Epicureanism’s ethical or metaphysical purity (as discussed earlier). His critique in De immenso suggests he saw Epicureanism as a stepping stone—useful but incomplete—lacking the divine vitality he championed. If you’re looking for more on how Bruno viewed other ancient thinkers or want me to dig into another work for specific references, let me know! What’s the next angle you’re thinking about here?

This is to start the subforum and open a thread on the distinctions and differences between Epicurus and "Pantheism," which is a wide topic but often identified with Spinoza. One reason for posting this now is that in reading Matthew Stewart's "Nature's God," it is being impressed on me that the early American and British deists were significantly more "pantheistic" than Epicurean in their view of "god." This is distinction that deserves to be made clear. (Note: I see that we had a thread devoted to discussion of this about a year ago here.)

Key Differences (per Chatgpt):

Epicureanism and pantheism represent fundamentally different philosophical systems, particularly in their metaphysical and theological assumptions. Below are the key differences between the two:

1. View of the Divine

• Epicureanism:
  Epicurus believed that gods exist, but they are entirely indifferent to human affairs and do not intervene in the world. They are composed of atoms, reside in the intermundia (spaces between worlds), and serve only as models of tranquil existence. Epicurean theology is non-theistic in effect, as divine beings play no role in cosmology or ethics.
• Pantheism:
  Pantheism holds that God and the universe are identical—God is not a separate personal being but is immanent in all things. The divine is everywhere and everything. This view is typically theologically affirming, seeing divinity in nature and existence itself.

2. Metaphysics (Nature of Reality)

• Epicureanism:
  It is strictly atomistic and materialist. All that exists are atoms and void. There is no divine order or cosmic consciousness. The soul is physical and perishes with the body. Nothing exists beyond the natural, observable world.
• Pantheism:
  Pantheism often includes a spiritual or holistic metaphysics, seeing reality as unified and divine. While some pantheists are naturalistic (e.g., Spinoza), others view the universe as a manifestation of spiritual essence or consciousness.

3. Ethics

• Epicureanism:
  The highest good is pleasure, defined as the absence of pain (aponia) and disturbance (ataraxia). Ethical behavior arises from prudence and the desire to live a pleasurable, peaceful life, free from fear and physical discomfort.
• Pantheism:
  Ethical systems within pantheism vary but often emphasize harmony with nature, reverence for all life, and moral behavior grounded in a sense of cosmic unity. Ethics is frequently derived from spiritual intuition or the perceived sacredness of the universe.

4. Teleology and Purpose

• Epicureanism:
  The universe has no purpose or design. Natural phenomena are the result of atomic motion and chance. There is no final cause or overarching direction to the cosmos.
• Pantheism:
  Pantheistic systems often imply a unifying purpose or order, whether moral, spiritual, or cosmic. The universe may be seen as unfolding according to rational or divine principles.

5. Death and the Afterlife

• Epicureanism:
  Death is the end of consciousness; the soul dissolves, and thus there is no afterlife. Fear of death is irrational and a major source of human anxiety.
• Pantheism:
  Views vary. Some pantheists believe in a form of spiritual continuation, such as merging with the universal whole. Others, especially naturalistic pantheists, may reject personal immortality but affirm a kind of ongoing cosmic existence.

In summary, Epicureanism is a secular, materialist philosophy focused on individual tranquility through natural understanding, while pantheism is a metaphysical worldview that equates the universe with divinity, often carrying spiritual or holistic ethical implications.

Key Differences (per Grok):

1. View of the Divine:
   • Epicureanism: Gods are real but irrelevant, uninvolved, and not the universe itself. They’re just perfect beings living apart.
   • Pantheism: God is identical with the universe; everything is divine, with no external or separate deities.
2. Metaphysical Foundation:
   • Epicureanism: Strictly materialist, with atoms and void as the basis of reality. Rejects any spiritual or immaterial essence.
   • Pantheism: Often monistic, seeing reality as a unified whole, sometimes with a spiritual or quasi-spiritual dimension (e.g., in Spinoza’s substance or mystical interpretations).
3. Ethical Focus:
   • Epicureanism: A clear hedonistic ethic centered on personal pleasure and tranquility through simple living and rational choices.
   • Pantheism: Ethics are less defined, often derived from the sense of unity with nature or rational alignment with the cosmos, varying by thinker.
4. Purpose and Practice:
   • Epicureanism: Practical and individual-focused, emphasizing friendship, moderation, and freedom from fear to achieve happiness now.
   • Pantheism: Often contemplative or cosmic in scope, aiming for harmony with the universe or understanding of one’s place in the whole.
5. Relation to Religion:
   • Epicureanism: Dismisses religious fear and superstition as obstacles to happiness, though it allows gods as philosophical constructs.
   • Pantheism: Embraces a religious sensibility by divinizing the universe, often reinterpreting traditional beliefs in a naturalistic way.

Among many other things, the wikipedia entry on Pantheism identifies the Stoics as pantheists:

Comparison with non-Christian religions

Some 19th-century theologians thought that various pre-Christian religions and philosophies were pantheistic. They thought Pantheism was similar to the ancient Hinduism^{[19]: pp. 618}philosophy of Advaita (non-dualism).^[58]

19th-century European theologians also considered Ancient Egyptian religion to contain pantheistic elements and pointed to Egyptian philosophy as a source of Greek Pantheism.^{[19]: pp. 618–620}The latter included some of the Presocratics, such as Heraclitus and Anaximander.^[59] The Stoics were pantheists, beginning with Zeno of Citium and culminating in the emperor-philosopher Marcus Aurelius. During the pre-Christian Roman Empire, Stoicism was one of the three dominant schools of philosophy, along with Epicureanism and Neoplatonism.^[60][61] The early Taoism of Laozi and Zhuangzi is also sometimes considered pantheistic, although it could be more similar to panentheism.^[49]

Cheondoism, which arose in the Joseon Dynasty of Korea, and Won Buddhism are also considered pantheistic. The Realist Society of Canada believes that the consciousness of the self-aware universe is reality, which is an alternative view of Pantheism.^[62]

We've had lots of threads in the past about people who were Epicurean-adjacent or somewhat Epicurean, but I thought I'd ask the AI engines: "Who was the last philosopher who explicitly followed Epicurus?" to see if it produced any unexpected names. The only one chatgpt produced with which I wasn't very familiar was Guilio Vanini, thought I did see him recently mentioned in the Matthew Stewart book.

Though he's regularly mentioned I don't think we have a thread here on Michael Onfrey - maybe we should, as both Chatgpt and Grok refer to him. I'd also like to know if anything relevant survives from Vanini.

Identifying the last philosopher who explicitly followed Epicurus depends on how one defines both “philosopher” and “explicitly followed.” However, a few noteworthy modern figures continued to advocate for Epicurean ideas in a conscious and deliberate manner, often citing Epicurus by name and aligning themselves with his core doctrines:

1. Thomas Jefferson (1743–1826)
Jefferson famously declared himself an Epicurean in a 1819 letter to William Short, writing:

"I too am an Epicurean. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy..."

Though Jefferson was not a professional philosopher in the academic sense, he deeply engaged with Epicurean ethics and incorporated its principles into his vision of personal liberty and political philosophy.

2. Frances Wright (1795–1852)
Wright was a 19th-century Scottish-American writer and social reformer who openly promoted Epicurean materialism and ethics, including the pursuit of pleasure grounded in reason. She wrote and lectured extensively on Epicureanism and defended it against Christian moralism.

3. Giulio Cesare Vanini (1585–1619)
A lesser-known Italian philosopher, Vanini revived atomist and Epicurean ideas during the Renaissance and was eventually executed for his views. He defended naturalistic explanations of the world, aligning with Epicurean physics and atheistic interpretations.

4. Michel Onfray (b. 1959)
In more recent times, French philosopher Michel Onfray has advocated for a return to Epicurean philosophy. His "La puissance d'exister" (The Strength to Exist) and "Le Ventre des philosophes" (The Philosophers' Stomach) draw directly on Epicurus, promoting hedonism, materialism, and atheism. Onfray identifies himself with the Epicurean tradition and critiques the neglect of Epicurus in mainstream philosophical discourse.

Summary
While Thomas Jefferson and Frances Wright were among the last historically prominent individuals to explicitly identify with Epicurus in a philosophical sense, Michel Onfray is arguably the most active contemporary philosopher to carry the Epicurean torch into the 21st century.

Grok3 said:

Identifying the last philosopher who explicitly followed Epicurus is tricky, as Epicureanism has waxed and waned over centuries, often blending with other schools of thought. The most prominent figure historically tied to explicitly following Epicurus is likely Lucretius, the Roman poet and philosopher of the 1st century BCE, whose work De Rerum Natura is a detailed exposition of Epicurean philosophy, particularly its physics, ethics, and rejection of superstition. Lucretius didn’t just parrot Epicurus; he adapted and expanded his ideas for a Roman audience, making him a clear disciple.

After Lucretius, Epicureanism continued in various forms, but explicit followers become harder to pin down. By the late Roman period, Epicureanism was often criticized or absorbed into other traditions, like Stoicism or early Christian thought. In later centuries, figures like Pierre Gassendi in the 17th century revived Epicurean ideas, particularly atomism and hedonistic ethics, but Gassendi’s work was more of a synthesis, blending Epicurus with Christian theology, so it’s not "pure" Epicureanism.

If we’re looking for someone more modern who explicitly identified with Epicurus without heavy reinterpretation, you’d likely end up with niche thinkers or scholars rather than major philosophers. For instance, in the 19th and 20th centuries, some secular humanists or utilitarians (like certain followers of Bentham or Mill) echoed Epicurean themes—pleasure as the highest good, avoidance of pain—but they didn’t explicitly call themselves Epicureans.

The truth is, after Lucretius, Epicureanism as a distinct, explicit tradition faded, resurfacing more as an influence than a direct lineage. If you’re after someone specific beyond Lucretius, I’d need more context on what counts as "explicitly following" for you—does it mean verbatim agreement, or just heavy inspiration? Alternatively, I can dig into specific periods or regions for you. What do you think?

If you’re looking for a specific name, I’d say the trail goes cold after Lucretius for truly "pure" followers, with later figures like Gassendi or Jefferson being the closest but still not fully aligned. If you want me to explore a particular era or community further, let me know—maybe there’s a modern Epicurean hiding in plain sight. What’s your take on what "purely" means here? That might help narrow it down.

Welcome to Episode 276 of Lucretius Today. This is a podcast dedicated to the poet Lucretius, who wrote "On The Nature of Things," the most complete presentation of Epicurean philosophy left to us from the ancient world.

Each week we walk you through the Epicurean texts, and we discuss how Epicurean philosophy can apply to you today. If you find the Epicurean worldview attractive, we invite you to join us in the study of Epicurus at EpicureanFriends.com, where we discuss this and all of our podcast episodes.

This week we continue our series covering Cicero's "Tusculan Disputations" from an Epicurean viewpoint. This series addresses five of the greatest questions in philosophy, with Cicero speaking for the majority and Epicurus the main opponent:

1. Is Death An Evil? (Cicero says no and Epicurus says no, but for very different reasons)
2. Is Pain An Evil? (Cicero says no, Epicurus says yes)
3. Does the Wise Man Experience Grief and Fear? (Cicero says no, Epicurus says yes)
4. Does the Wise Man Experience Joy and Desire? (Cicero says no, Epicurus says yes)
5. Is Virtue Sufficient For A Happy Life? (Cicero says yes, Epicurus says no)

As we found in Cicero's "On Ends" and "On The Nature of the Gods," Cicero treated Epicurean Philosophy as a major contender in the battle between the philosophies, and in discussing this conflict and explaining Epicurus' answers to these questions, we will deepen our understanding of Epicurus and how he compares to the other major schools.

Theis week we turn our attention further to "Is Death An Evil," and we will read beginning in Section XXIV where the discussion continues with more about the Pythagorean / Platonic view of the human soul.

We may be able to conclude the discussion of life after death this week, as most of the major arguments have already been given, and the remainder from 24 - 30 seems more like miscellaneous wrap-up.

Please understand that the leaders of this forum are well aware that many fans of Epicurus may have sincerely-held views of what Epicurus taught that are incompatible with the purposes and standards of this forum. This forum is dedicated exclusively to the study and support of people who are committed to classical Epicurean views. As a result, this forum is not for people who seek to mix and match some Epicurean views with positions that are inherently inconsistent with the core teachings of Epicurus.

All of us who are here have arrived at our respect for Epicurus after long journeys through other philosophies, and we do not demand of others what we were not able to do ourselves. Epicurean philosophy is very different from other viewpoints, and it takes time to understand how deep those differences really are. That's why we have membership levels here at the forum which allow for new participants to discuss and develop their own learning, but it's also why we have standards that will lead in some cases to arguments being limited, and even participants being removed, when the purposes of the community require it. Epicurean philosophy is not inherently democratic, or committed to unlimited free speech, or devoted to any other form of organization other than the pursuit by our community of happy living through the principles of Epicurean philosophy.

One way you can be most assured of your time here being productive is to tell us a little about yourself and your background in reading Epicurean texts. It would also be helpful if you could tell us how you found this forum, and any particular areas of interest that you have which would help us make sure that your questions and thoughts are addressed.

We have found over the years that there are a number of key texts and references which most all serious students of Epicurus will want to read and evaluate for themselves. Those include the following.

"Epicurus and His Philosophy" by Norman DeWitt

The Biography of Epicurus by Diogenes Laertius. This includes the surviving letters of Epicurus, including those to Herodotus, Pythocles, and Menoeceus.

"On The Nature of Things" - by Lucretius (a poetic abridgement of Epicurus' "On Nature"

"Epicurus on Pleasure" - By Boris Nikolsky

The chapters on Epicurus in Gosling and Taylor's "The Greeks On Pleasure."

Philodemus "On Methods of Inference" (De Lacy version, including his appendix on relationship of Epicurean canon to Aristotle and other Greeks)

"The Greeks on Pleasure" -Gosling & Taylor Sections on Epicurus, especially the section on katastematic and kinetic pleasure which explains why ultimately this distinction was not of great significance to Epicurus.

It is by no means essential or required that you have read these texts before participating in the forum, but your understanding of Epicurus will be much enhanced the more of these you have read. Feel free to join in on one or more of our conversation threads under various topics found throughout the forum, where you can to ask questions or to add in any of your insights as you study the Epicurean philosophy.

And time has also indicated to us that if you can find the time to read one book which will best explain classical Epicurean philosophy, as opposed to most modern "eclectic" interpretations of Epicurus, that book is Norman DeWitt's Epicurus And His Philosophy.

That's a good question and apparently subject of dispute, but I'd go with literally nothing but pleasure itself as being good in itself, and everything else, including prudence and friendship, being intstrumental, and not the same as pleasure itself.

While it would depend on how strictly you define friendship, I've found that even friendship can sometimes be a pain

That's more of a joke than a point, but I see Epicurus' point in wanting to be extremely rigorous in making it clear that only "pleasure" is always pleasurable.

Palmer on the origin of motion (eternal, a property of matter)

Motion As A Property Of Elemental Bodies - Eternal and Not Caused By An Outside Force

The following is Chapter 24 of Elihu Palmer's "Principles of Nature" from 1806. If I read this correctly, here he endorses motion as an eternal quality of matter, and he does not look for some cause of motion outside of matter, as did some of the other Deists.

CHAPTER XXIV. - MATTER AND POWER; ORIGIN OF MOTION; LIBERTY AND NECESSITY.

The universe is composed of an infinite mass of matter;(1) or at least, to the human mind, it is infinite, because to this mass no assignable boundary can be affixed. Space is unlimited or infinite, and in this vast expanse, innumerable bodies of matter, of different magnitudes, are continually performing variegated revolutions. Upon these bodies or higher spheres of existence, other smaller bodies are discovered, of specific modification and powers, essentially connected in their natures with the larger orbs to which they respectively belong. In all these bodies, great and small, motion is an essential and inherent property. The inactivity of matter is a doctrine contradicted by the evidence of our senses, and the clear deductions of a sound philosophy. It is impossible to conceive matter without power, or of power without matter; they are essentially connected; their existence is interwoven, and cannot be separated even in thought. The ancient doctrine of matter and motion, so long exploded, and so much calumniated by theological priests, will probably, at some future day, be considered as bearing a very strong relation to a pure and incorruptible philosophy. Supernatural religion has blinded the human understanding, and prevented upon this subject every clear and correct conception.

[1. The New York Reviewers, in the review which they took of the first edition of this work, after quoting a number of detached sentences from this chapter, make the following observation: "Those who have read the most celebrated atheistical writers, will see that, Mr. Palmer is as determined an Atheist as any of them." It is presumed that these learned Reviewers mean to take the Bible and Testament descriptions of God as the standard of theism. Let us then examine the case upon this ground, and we shall soon discover what it is to be an Atheist in the estimation of the New York Reviewers. "And the Lord spake unto Moses, face to face, as a man speaketh unto his friend," (See Exodus chap. xxxiii. 11.) "And I will take away mine hand, and thou shalt see my back parts; but my face shall not be seen." (See Exodus chap. xxxiii. 23.) From these passages it appears, that God is represented in the form and shape of a man, and that such were the ideas of the inspired and chosen people of God concerning the Creator. But there is another passage in the New Testament, which places this matter in a still stronger light. In Paul's Epistle to the Hebrews, speaking of Jesus Christ, he says that he was the brightness of his father's glory, and the express image of his person. Now both believers and infidels agree, that Jesus was in the shape and form of a man; and as he was like God, of course God must be like him; therefore, the Christian God is like a man, perhaps like one of the New York Reviewers. Now the fair deduction from all this is, that whosoever doth not believe that God is like a New York Reviewer, is a most profane and abominable Atheist. What a sublime and majestic spectacle of theism do these "learned" men present to the human mind! In another place they charge the author of this work with "affectation, inordinate vanity, and the want of comprehensive views." How wonderfully comprehensive must be the views of those who can place the material universe upon the shoulders of a God, resembling in his existence a New York Reviewer. Such "literary" heroes ought triumphantly to exclaim, that they have excelled in brilliancy of conception, and in comprehensive views, the story of the Indian, which places the earth upon a turtle's back, and then declares the turtle stands upon nothing! Permit "us" miserable Atheists to bow with great humility before such "splendid" talents, and such "comprehensive views". Go on, gentlemen Reviewers, and console yourselves in the preservation of that Trinitarian or polytheistical scheme of religion to which you are so much attached; but remember, the moment will arrive in the succession of future ages, when those very mental "energies" of the intelligent world, which you sneer at so much, will sweep away the whole bundle of theological nonsense, leaving only the mighty power by which the universe is sustained; and of the shape or form of this power, the New York Reviewers have as little idea as "the author of the Principles of Nature", or any of the profane and abominable Atheists, whom the advocates of Christianity long ago sent down to the dismal abodes of the damned, to dwell for ever in hell fire.]

A belief in spirits had nearly, at one time, overturned the empire of real existence; the power and excellence of matter were exploded to make room for a world of fictions; of phantoms and things that had in nature no positive, no real, or substantial being. Filled with this idea, the dreams of theology were substituted for philosophic truth, and fanaticism usurped the domination of reason. Philosophers joined in the race of spiritual or material glory, and the united effect of their different opinions constituted the annihilation of nature. The spiritualists contended against the matter, and the materialists against spirits; thus sweeping away, by their opposite systems, every species of existence. Matter, and its diversified modes of operation, are the only things of which human intelligence can take cognizance. It is this vast body of which demands our most serious investigation; it is this in which we are interested, and with which we are most closely connected. Much has been said concerning dead or inactive matter; much concerning its vis inertia; but an appeal may be safely made to the phenomena of the physical world for a complete refutation of this opinion. Every fact that strikes our eyes, or presents itself to the contemplation of the understanding; every movement in nature furnishes are argument against a doctrine so unphilosophic and erroneous. Every thing that we behold; all the elements are in continual flux; agitation or motion is a universal and eternal law of nature.

The earth, the ocean, and the atmosphere, are constantly in a high degree of action; the evidence of these facts are presented to every living creature. The raging element of fire is never wholly at rest; it is always powerfully or more silently operating in every part of the world. If these ideas are controverted, let man inquire into their truth by an immediate recourse to the energetic movements of physical existence. In regard to fluids, this opinion, perhaps, will not be controverted; but it will be asked, whether it be equally true in regard to solids? To this, the answer is unequivocally in the affirmative; at least so far as it relates to the question, motion or not motion, action or not action. Beside the general revolutionary motion which the earth has round the sun, the parts of its solid materials are constantly combining and dissolving, as may be proved by the smallest recurrence to the organic structure of vegetable and animal life, and the property of disorganization essential to each specific mode of existence. It will, however, be contended, that if this be true in regard to organic matter, or to vegetable and animal existence, it will not hold equally in regard to other portions of the material world. There is, undoubtedly, a difference in the activity of matter, or in degrees of motion, of which the several parts are capable; but there is no such thing as absolute incapacity of motion; no such thing as absolute and entire rest. For the truth of this, an appeal is made to the power, pressure, and dissolving operation of the most inert and stupid portions of material substance. An appeal is made also to the activity of the most stupid parts of matter, in the composition of vegetable productions. What regular industry do the solids and fluids exhibit in the formation of a common vegetable? The march of each particle to its destined post is with firm and philosophic step; with constancy and physical zeal. There is no such thing as dead matter; all is alive, all is active and energetic. The rays of the sun fructify the earth, and these are considered among the portions of dead matter.

These rays, however, are so active, as to travel 95,000,000 of miles in the space of seven minutes and a half; a celerity of motion which substantiates, beyond all contradiction, their essential power and activity. Every fact, in the physical world, forces conviction in the human mind, and proves the energetic nature of the material system. An investigation of the properties of matter, a full development of its modes of operation, would lead to the most salutary consequences, by instructing man in regard to his true predicament in nature, and reconciling him to his fate. To corroborate the ideas which have already been suggested upon this subject, the following strong and philosophic reflections are taken from an anonymous pamphlet, entitled, An Essay on Matter. "All matter is possessed of life, spirit, action, or motion. What is called inanimate matter, owes its motion of life no more to the elements, than what is acknowledged to be animate. This elementary influence presupposes the animation of bodies; for as these cannot move without that influence, so neither can that influence where there is no life. To say that the elements alone give motion, is to say that the elements give life, which is denying a universal agent, or making him appear to act more by intermediate agents than philosophy will allow. No one, I presume, will doubt the independent motion of matter in that form which we name animal, at least, that it is as independent as man; we allow animals to be a composition of matter without soul, yet we allow them to be possessed of the principle of motion. It is from this motion solely that we allow them to be possessed of life; for there is nothing beside that can or does influence the mind to make it assent to this truth, that animals have life; and it is from the different combinations of motion and matter that we form our ideas of the different kinds of animals. It is then from motion, and nothing else, that we judge of, and allow matter of a particular kind of composition to be possessed of the living principle; the same evidence must have the same weight in every other kind of composition. Wherever motion is discoverable in matter, be the form of it what it may, we must acknowledge it to entertain the living principle; but it may be said, that though motion be an evidence of life in matter in certain forms, and where the motion is of certain kinds, yet motion of every kind will not prove the existence of life in matter of every form.

This absurdity of supposing a 'caput mortuum', must appear to every one who considers the connection and dependence which exits in all bodies upon each other, the motion which this connection supposes, and life which motion evidences. There is a perpetual exchange of matter with matter of every form. The animal creation, for instance, is constantly exchanging parts with the earth and its atmosphere. If the matter composing animals be animate, and that of the earth inanimate, how can these be united? This would be to suppose that two opposites could exist in one body, whereas it is the nature of opposites to recede from each other, and nothing can be greater opposites than life and death. The independent motion of matter in that form called vegetable, can be as little doubted as in animals. Storms, earthquakes, fires, floods, do not cause vegetation any more than they do generation in animal. The natural or preternatural motion of bodies, no more contributes to the motion of matter in vegetables, than in animals; they, like us, receive only the natural and gentle influence of the elements, and thereby mark a link in that chain which connects all matter, and which is the harmony of creation. We shall be more particular in speaking of motion in vegetables, when we come to treat of the nicer operation of matter in that action which we call thinking. We come now to speak of the motion of matter in those forms where it is less observable upon a superficial view of things; but where, upon a nearer view, it is not less evident than in either of the other forms mentioned."

"Whoever doubts the motion of matter in the form of a stone, let him take the trouble to look upon the first rock in his way, and he will see its surface mouldering. Whatever decays, must be replenished; for matter cannot waste. Stones, then, give to, and receive matter from other bodies. Circulation is a very perfect motion. Will any one assert, that the motion of giving and receiving of its substance, does not exist in the stone, with only that assistance, which, in common with us and animals, it receives from the elements? The motion of matter in the various forms of minerals is more observable, as it is more lively. There is a constant fluctuation of matter in all mineral bodies. When miners open a mine, and do not find the ore they are in pursuit of, in the quantity which they expected, they say the mine is not ripe, and close it up again, that the metal may have time to grow. If matter have not the vital principle, then I have the power of creating. The bulk of my form is increased by the matter which in the action of eating, inspiration, and absorption, I add to myself. If this matter have not the principle of life, how can I make it partake of me, and thereby partake of life? Can I unite dead and living things, or can they be united in me? Chemists tell us that the union of bodies depends upon the affinity, i.e. the likeness which matter in one form has to matter in another form, and tell us no further. We have before mentioned the different kinds of union produced by affinity, the perfect and imperfect; but what gives the quality of union, and preserves the existence of the compound? It is the living principle in one body, inclining it to associate with the living principle in another body. Without this living principle, that inclination which supposes motion could not exist."

The above observations exhibit, with philosophic clearness, the nature and property of matter. It is by a constant recurrence to the operations of the material world, that man will be able to discover those solemn and important truths on which his happiness is founded. Our bodies are composed of the elements, compounded and organized by the skill and energy of nature; from this organization, certain consequences necessarily result; composition, decomposition, and recomposition, are established in the order, and supported by the laws of physical existence. The materials which are employed in any specific composition possess inherent and indestructible qualities, but the result may be augmented and power increased by organic construction. Thus, for instance, matter in its most simple form, may, perhaps, be destitute of intelligence; but when combined and modified in the form of a man, intellect is a uniform consequence. It is impossible to say, how far the properties or qualities of matter may extend in a simple and uncompounded state. It is impossible from the want of communication, to affirm, or deny with absolute certitude, relative to the internal essence of the particles of material existence. There must be in the essence of matter a capacity, when combined in certain forms, to produce specific results. The principle of life must be essentially inherent in the whole system and every particle thereof; but to attribute to each particle a specific kind of life analogous to that which is discovered in large compositions of matter, cannot, perhaps, be warranted by the knowledge or experience of nature. In all the specific modifications of life, disorganization, or death, is a universal law; but the universality of this law among specific combinations upon the earth, cannot, perhaps, be extended to the earth itself. The analogy is broken, when we go from individuals or particulars to generals or universals. But more of this hereafter.

It is by the laws of motion that combinations are formed, it is by the same laws they are dissolved. Motion is an essential property of universal existence. The following paragraph upon this subject, is taken from the System of Nature, a powerful work, translated from the French of the celebrated and philosophic Mirabaud.

"Every thing in the universe is in motion; the essence of nature is to act, and if we consider attentively its parts, we shall see that there is not a particle that enjoys absolute repose. Those which appear to us to be deprived of motion, are, in fact, only in relative or apparent rest; they experience such an imperceptible motion, and so little marked, that we cannot perceive the changes they undergo. All that appears to us to be at rest, does not remain, however, one instant in the same state. All beings are continually breeding, increasing, decreasing, or dispersing, with more or less dulness or rapidity. The insect called 'Ephemeron' is produced and perishes the same day; of consequence, it very rapidly experiences the considerable changes of its being. The combinations formed by the most solid bodies, and which appear to enjoy the most perfect repose, are decomposed, are dissolved in the course of time. The hardest stones are by degrees destroyed by the contact of air. A mass of iron, which time has gnawed into rust, must have been in motion from the moment of its formation in the bowels of the earth, until the instant that we see it in this state of dissolution." Mirabaud's System of Nature, Vol. I. page 42.

A philosophic investigation into the laws of nature, would probably furnish a pretty clear solution of all the phenomena of the intellectual world. A certain portion of matter organized upon a certain specific plan, produces, in the animal we denominate man, all the energetic and astonishing effects of mind.

A question has been stated among speculative metaphysicians, whether it be not probable that the earth and all the higher spheres of existence in the planetary world, are possessed of strong intellectual powers? Indeed, this conjecture has been carried so far as to combine the whole of material existence, and attribute to it all the properties, qualities, and powers of intelligent life. Nature is considered as possessing a central power, a brain, or cognitive faculty, whose operations on a higher scale are supposed to be analogous to the brain or thinking faculty of man. And this, perhaps, would be the most philosophic method by which to arrive at the idea of supreme intelligence, or the governing power of the universe. But whether the planets in their individual capacity be considered as intellectual beings, or whether nature in its aggregate combination be thus considered, are questions of speculation, concerning which, perhaps the human mind will never receive any adequate or satisfactory information. Man, however, should not fear to extend his contemplation to the whole of nature, and, if possible, subject the whole to the powerful examination of his intellectual energies.

From the ideas that have been disclosed in this chapter, it will be easy to perceive, that if the inquiry were now made, "where is the origin of motion?" the philosophic answer would be, that it is in matter itself, co-essential and co-eternal with it, and cannot be separated from any part thereof, not even in thought.

A further question, in some measure connected with the present subject, is that which relates to the principle of action in the mind of man, or the opinions relative to Liberty and Necessity. Moralists and metaphysicians have for a long time been in a state of altercation on this subject, nor is the point of discussion between them yet completely settled. Perhaps the preceding reflections may furnish us with some information and aid in the solution of a problem so difficult. The principle of motion and action must exist essentially somewhere; if this principle be in matter itself, or in a foreign agent whose existence is presumed to be wholly extraneous from the body of nature, the same consequence will, however, necessarily follow. Man is an organized being, possessing powers of motion and action; if the motion of which man is susceptible be the result of the essential nature of matter in specific organic construction, the motion in this being must be as independent, absolute, and self-existent, as in the body or any part of nature; that is, it must belong to the thing itself, co-essential with its being, and acting by the internal force of the principle itself. If the principle of motion be sought for in any intellectual agent foreign to the body of nature, it must be independent and absolute there; it must be self-existent, and as man must have proceeded from one or the other of these two sources, he must be like the source itself from which he emanated, and possess, in a partial degree at least, that independence of power and action, which are so justly to be attributed to these two great sources of all existence. To suppose an infinite series in the principle of causation, exhibits nothing more than a feeble effort of the mind, to get clear of a metaphysical difficulty. The last point that is discovered, includes in it an equal necessity of discovering another point, on which the last may depend for its existence. The links in this chain would become innumerable, its length infinite, and, after all, the difficulty remain as great as ever.

This doctrine, concerning the origin of motion, and of giving a solution to the subject by means of an infinite series in the principle of causation, can never satisfy the mind that is seriously in quest of a first point, or essential spring of every action; in short, it is nothing better than the story of the Indian, who placed the earth upon a turtle's back, and afterwards declared, that the turtle stood upon nothing. The fact is, man is independent in his mind; it is the essence of his nature to act, and he feels, or ought to feel, that he is not the slave of any of the phantoms of superstition, or the fine spun reasonings of metaphysical philosophers.

In a moral point of view, the doctrine of necessity is still more objectionable, and goes to the destruction of all human merit, and with it the dignity of the human character. If man be a moral slave, his actions in relation to himself are neither good nor bad; he is impelled by an irresistible necessity, and can no more in justice be punished for his conduct, than a cannonball, which is propelled forward by the explosion of gunpowder, can be punished for taking off a man's leg. The one upon the doctrine of necessity is as much a moral agent as the other, and punishment, in both cases, equally absurd. It is essential to the dignity of man that he be free and independent, both morally and politically. Political slavery is not more derogatory to the human character, and human energy, than moral slavery. They both sink and brutalize mankind; they both have a tendency to diminish his efforts, and destroy his active zeal in the cause of virtue. It is essential to the true and elevated character of an intellectual agent, that he realize the strength of his powers; that he be confident in his energies; that he hold in suitable contempt every species of moral and political despotism. This sentiment will raise him from a degraded condition, and form him into the stature of a perfect man in the glorious system of nature.

One of the things about this which Matthew Stewart comments on is how interesting it was to the deists of this period to think about life on other planets and throughout the universe, and that this is in fact how the "Sermon On Natural Religion" ends:

Please say "Hello" by introducing yourself, tell us what prompted your interest in Epicureanism and which particular aspects of Epicureanism most interest you, and/or post a question.

This forum is the place for students of Epicurus to coordinate their studies and work together to promote the philosophy of Epicurus. Please remember that all posting here is subject to our Community Standards / Rules of the Forum our Not Neo-Epicurean, But Epicurean and our Posting Policy statements and associated posts.

Please understand that the leaders of this forum are well aware that many fans of Epicurus may have sincerely-held views of what Epicurus taught that are incompatible with the purposes and standards of this forum. This forum is dedicated exclusively to the study and support of people who are committed to classical Epicurean views. As a result, this forum is not for people who seek to mix and match some Epicurean views with positions that are inherently inconsistent with the core teachings of Epicurus.

All of us who are here have arrived at our respect for Epicurus after long journeys through other philosophies, and we do not demand of others what we were not able to do ourselves. Epicurean philosophy is very different from other viewpoints, and it takes time to understand how deep those differences really are. That's why we have membership levels here at the forum which allow for new participants to discuss and develop their own learning, but it's also why we have standards that will lead in some cases to arguments being limited, and even participants being removed, when the purposes of the community require it. Epicurean philosophy is not inherently democratic, or committed to unlimited free speech, or devoted to any other form of organization other than the pursuit by our community of happy living through the principles of Epicurean philosophy.

One way you can be most assured of your time here being productive is to tell us a little about yourself and your background in reading Epicurean texts. It would also be helpful if you could tell us how you found this forum, and any particular areas of interest that you have which would help us make sure that your questions and thoughts are addressed.

Please check out our Getting Started page.

We have found over the years that there are a number of key texts and references which most all serious students of Epicurus will want to read and evaluate for themselves. Those include the following.

"Epicurus and His Philosophy" by Norman DeWitt

The Biography of Epicurus by Diogenes Laertius. This includes the surviving letters of Epicurus, including those to Herodotus, Pythocles, and Menoeceus.

"On The Nature of Things" - by Lucretius (a poetic abridgement of Epicurus' "On Nature"

"Epicurus on Pleasure" - By Boris Nikolsky

The chapters on Epicurus in Gosling and Taylor's "The Greeks On Pleasure."

Cicero's "On Ends" - Torquatus Section

Cicero's "On The Nature of the Gods" - Velleius Section

The Inscription of Diogenes of Oinoanda - Martin Ferguson Smith translation

A Few Days In Athens" - Frances Wright

Lucian Core Texts on Epicurus: (1) Alexander the Oracle-Monger, (2) Hermotimus

Philodemus "On Methods of Inference" (De Lacy version, including his appendix on relationship of Epicurean canon to Aristotle and other Greeks)

"The Greeks on Pleasure" -Gosling & Taylor Sections on Epicurus, especially the section on katastematic and kinetic pleasure which explains why ultimately this distinction was not of great significance to Epicurus.

It is by no means essential or required that you have read these texts before participating in the forum, but your understanding of Epicurus will be much enhanced the more of these you have read. Feel free to join in on one or more of our conversation threads under various topics found throughout the forum, where you can to ask questions or to add in any of your insights as you study the Epicurean philosophy.

And time has also indicated to us that if you can find the time to read one book which will best explain classical Epicurean philosophy, as opposed to most modern "eclectic" interpretations of Epicurus, that book is Norman DeWitt's Epicurus And His Philosophy.

(If you have any questions regarding the usage of the forum or finding info, please post any questions in this thread).

Welcome to the forum!

Thanks. I'll have a lot more to say when I finish the book but I'm definitely impressed so far.
