I assume that they're the same thing. The original title is unclear, DeLacey discusses this on pages 10-11.

Quote from Cassius

Godfrey are your references from chapter two quotes, or your own summaries?

Some of these direct quotes but most are my paraphrases. Also I've included definitions from other sources to try to make sense of the DeLacey commentary. This is all out of my wheelhouse and the terminology is new to me; these notes are literally my attempt to read and make sense of this material. Hopefully it's of some value but it's definitely not "gospel!"

I agree that a lot more information is needed to make the subject clear. This material is dense and extremely confusing for a novice such as myself. As you point out Cassius it's difficult to understand what is meant by "signs," and that seems to be the most basic idea involved! Hopefully the additional papers will bring some clarity.

Quote from Martin

We don't consider maps necessary to our being able day-to-day to navigate in reality because we have internalized them and use them intuitively without realizing it.

Similarly, we have internalized "syllogistic" logic such that we use it in our day-to-day thinking when fully awake without realizing it.

No

Although one might argue that this is a chicken or egg conundrum, I think it's not and I have to disagree with this statement. A map is a two dimensional representation of a three dimensional environment. We navigate a 3D environment by noting markers and our subconscious forms connections between these. I recall conversations between an architect, a geologist and a botanist. The architect navigated by noticing buildings, the geologist by noticing rock formations, and the botanist by noticing plants. Each was oblivious to the markers of the others. None of these systems of markers have anything to do with internalizing a map as commonly defined; a map is constructed by visualizing the markers in space and transferring them to paper.

Similarly, I see syllogistic logic as an attempt to represent ways of thinking, not as the way in which we think. Some of the greatest technical and creative innovations have occurred after a person has put aside a problem and allowed it to "bubble" in the subconscious mind. To say that this person is subconsciously performing syllogistic logic is such a stretch as to be ridiculous, in my opinion.

Thinking that a map precedes navigation or that syllogistic logic precedes thinking is similar to thinking that mathematics preceded matter. All of these are tools to try to help us understand the world.

Having said all of that, I do agree that we can and do internalize maps and/or logic and/or mathematics. But these are just instances of using the tools provided, and people use them to greater or lesser degrees depending on the way their minds work.

syllogism (noun):

- an instance of a form of reasoning in which a conclusion is drawn (whether validly or not) from two given or assumed propositions (premises), each of which shares a term with the conclusion, and shares a common or middle term not present in the conclusion (e.g., all dogs are animals; all animals have four legs; therefore all dogs have four legs ).

- deductive reasoning as distinct from induction. "this school of epistemology is highly advanced in syllogism and logical reasoning"

(from Oxford Languages online)

[EDIT BY CASSIUS: Here is a link to theDeLacey Translation including the DeLacy Appendix which gives a lot of background on the epistemology issues.]

(Note: these are my personal notes. Not all of these notes are from the book; some are from Google to help me further understand the basic ideas, and some are my"notes to self".)

Signs: what you see or what you think about

"All instruction is either about things or about signs; but things are learnt by means of signs. I now use the word “thing” in a strict sense, to signify that which is never employed as a sign of anything else: for example, wood, stone, cattle, and other things of that kind. Not, however, the wood which we read Moses cast into the bitter waters to make them sweet, nor the stone which Jacob used as a pillow, nor the ram which Abraham offered up instead of his son; for these, though they are things, are also signs of other things. There are signs of another kind, those which are never employed except as signs: for example, words. No one uses words except as signs of something else; and hence may be understood what I call signs: those things, to wit, which are used to indicate something else. Accordingly, every sign is also a thing; for what is not a thing is nothing at all. Every thing, however, is not also a sign. And so, in regard to this distinction between things and signs, I shall, when I speak of things, speak in such a way that even if some of them may be used as signs also, that will not interfere with the division of the subject according to which I am to discuss things first and signs afterwards. But we must carefully remember that what we have now to consider about things is what they are in themselves, not what other things they are signs of. AUGUSTINE, De Doctrina 1.2." From the Heidlblog

Chapter 2, Introduction to Philodemus On Methods of Inference

Per the Stoics:

- Common sign: exists whether the unperceived object that it signifies exists or not. Therefore not a reliable basis of inference.

- Particular sign: exists only when the unperceived object that it signifies exists. If the existence of the object signified is denied, then the existence of the sign must be denied as well. These provide the only reliable grounds for inference and are established through the purely formal test of contraposition.

- Contraposition: inference from a logically equivalent contrapositive.

- Contrapositive: "if not-B then not-A" is the contrapositive of "if A then B."

Per the Epicureans:

- The relation between sign and thing signified is learned only through perception, through the method of induction or analogy. We infer the nature of unperceived objects by analogy with the objects in our own experience.

- Inductive reasoning makes broad generalizations from specific observations; aims at developing a theory.

- Deductive reasoning works from general to specific; aims at testing a theory.

- If a constant connection between objects is not first established by perception, contraposition is impossible.

- Epicureans use inductive reasoning, and agree that common signs are not a valid basis of inference.

- Inconceivability, not logical necessity, is a criterion of a particular sign and is based on past experience. An inference from signs is valid if it is inconceivable that the sign exists when the thing signified does not. (page14) (Hmmm. What are some examples of this? )

- The four empirical criteria of truth: perception, anticipation, mental perception and feeling. Mental perception is defended and used in reference to knowledge of the gods.

Quote from Camotero

The last line quoted above is a testament to how reason is not to be disregarded, isn't it? Perhaps this is the type of true reason that we won't be able yo get by without?

If this reason isn't logic, or formal logic, could we agree that it could be "critical thinking"?

This seems to be a key distinction! Logic that is used to win arguments may lead to victory but not necessarily truth. Epicurus placed high value on wisdom and/or prudence, which I think can be equated to critical thinking. Reasoning of this sort has the goal of living well, not necessarily winning arguments.

Of course this begs the question: "how do you define prudence or critical thinking?" Film at 11

To expose my ignorance, one question that I have as I begin to work my way through DeLacey: how do "signs" fit into this discussion? It seems that words are signs; what about "first mental images," concepts... what else can be considered a sign? Do the Stoics have a different idea of what constitutes a sign than the Epicureans do? Just defining the language with which to discuss logic and methods of inference is confusing!

I stumbled upon this quote online, though I'm not sure if it's helpful:

Despite the anachronism it seems that this is what Epicurus was struggling against

Quote from Camotero

But how can logic be verified through the senses, if it is completely a mental thing. Wouldn't it be, logic should be constraint to material issues? Or that if it has to fly a bit into the ether, it should have a grounding back into maerial reality, otherwise it would be plain speculation about things that don't exist?

For me, it seems critical to ground logic in material reality and that's the purpose of the Canon. Think of the common example of "Bob is a man. All men are mortal. Therefore Bob is mortal." At least to my understanding, we need the Canon to provide evidence that Bob is a man and that all men are mortal, or neither of the two statements are verifiable and therefore the conclusion is not verifiable, even if it is "formally" correct. This is why I think it's important that the article linked to above in post #7 describes reasoning in the context of the scientific method.

Thanks for the link Camotero!

What I like about the descriptions in the linked article is that all three types of reasoning are discussed as part of the scientific method and subject to verification. What drives me crazy would appear to be deductive reasoning in which premisses are presented as true without proper examination. A particular conclusion is then accepted as true and used as a premiss for further argument. So as described in the article, proper examination and verification of each statement would lead to correct conclusions.

Quote from Cassius

When I think anticipation I can't help thinking of Carly Simon!

I tend to think of The Rocky Horror Picture Show

The entire operation of a computer is based on 1 and 0, which might be equated to pleasure and pain. Or not.

Methods of Inference sounds valuable and I confess that I haven't spent a lot of time with it.

The issue here, to me, is that I don’t see how higher and lower life forms relate to the idea of isonomia as presented by Cicero. Higher and lower life forms, both known and unknown, I see as intuitively obvious based on the Epicurean viewpoint. But if the only description of isonomia that we have is Cicero's, then I don’t see isonomia as a pertinent concept in EP.

So I think that finding a proper definition of isonomia is necessary if we are to be able to accurately evaluate its place in the philosophy. Unless I'm mistaken, I don't think that anyone here is questioning the existence of higher and lower life forms. It's just that Cicero seems to use isonomia to validate the divine, so if we think that isonomia is valid based on an agreed upon definition, then we need to evaluate what is meant by the divine, based on the definition of isonomia. That may lead right back to higher and lower life forms, but with my current understanding I don't see it doing so.

Quote from Cassius

The isonomia view would I think allow for an infinite progression / spectrum of advancement above us.

Quote from Cicero

From this principle it follows that if the whole number of mortals be so many, there must exist no less a number of immortals

First, I think that the Cicero quote is more accurate as to the meaning of isonomia: it sounds to me like it deals with opposites and not a progression or spectrum.

Second, I don't agree with Cicero's conclusion that there must be an infinite number of immortals: this seems like a juxtaposition of a Platonic ideal with a living reality. To me it's no more valid than saying "if the number of mortals be so many, there must exist no less a number of rocks." Ah, logic....

So the problem, I think, is determining what the "exact match and counterpart" of a mortal (a mortal defined as a living human being, subject to dying?) is, and if this would have been a useful idea for Epicurus. Although the idea of a spectrum of beings makes perfect sense to me, I don't understand that as isonomia. But of course I could be confused about that

From Cicero’s statement as well as from Alcmaeon, I don't see isonomy implying a hierarchy of beings. I read it as "equalities of opposites" (mortal/immortal, creation/destruction, good/evil, light/dark...).

This seems valid to a point, but it seems like at some point it could just turn in to sophistry or Platonism where one might name a random thing and then claim that another random thing is it's opposite, leading to endless logical nonsense. Come to think of it, the principle of isonomy requires that since there is an infinite amount of common sense in the universe, there must also be an equally infinite amount of idiocy in the universe

I wonder if this is what led Pyrrho down his path of not knowing?

That's an interesting question. On first pass I would say that it's the feeling of pain, and it's a good illustration of why sometimes we would choose to sacrifice ourselves because the pain of sacrifice would be less than the pain of seeing our child suffer.

On second pass, however, there is sensation and preconception involved, as well as feeling. Feelings don't just arise out of nowhere! So this is a good way to examine what a preconception might be in a particular instance. Would the preconception be a non-conscious expectation of a continuing relationship with the calf/child? I think that this begins to point out the "non conceptual" nature of a "preconception." In modern terms it might be called a non-conscious mental model arising from a non-conscious prediction loop, at least to my meager understanding.

Coincidentally this paper discussing isonomia showed up in my feed. I've only skimmed it as it's pretty academic, but what I gather is that isonomia refers to opposites and the idea that DeWitt is referring to is that in an infinite universe, if something exists, then so must it's opposite.

Apparently this relates to the pre-Socratic writer Alcmaeon's theory of health (ἰσονομία, equilibrium of opposite forces in the body) and disease (μοναρχία, domination of one excessive force).

In the past I've also been interested in the writing of Sarah Williams Goldhagen regarding embodied cognition. But she, as I recall, is a design critic. LFB is a neuroscientist and is more on point.

Here's one thread on her work:

How Emotions Are Made: The Secret Life of the Brain by Lisa Feldman Barrett

This book is about the “theory of constructed emotion,” which is based in experiments and research.

My goal in reading the book was to explore whether current neuroscience can add any clarity to the prolepseis, as there is so little remaining text concerning them. What I found is that it actually is relevant to the entire Canon. Though the subject of the book is emotions, it also covers sensations and feelings as well as what I think we can interpret as prolepseis. Note that although the author…

They were everywhere and I didn't even know it!

A Google search just informed me that the Cowsills' big hit was Hair. I had no idea... ah, nostalgia!

Joshua I like the compass analogy, but thinking about it further I have some reservations. The compass can show us where north is, but most often our goal isn't actually to travel north. So it's a reference, but pleasure is more properly a direct guide. I think this is one reason why True North has a troublesome Platonic feel.

As for the old man, it's not so much that he's followed the guide, or compass, of pleasure for his whole life. Speaking from my experience it's more a matter of learning from a series of mistakes to pay attention to the guide. Using another compass analogy: just as a compass wavers back and forth before settling on north, a young person is still wavering in search of the target but the old person has finished wavering and settled onto the target.
