Cf: Peirce's 1870 "Logic Of Relatives" : Overview

At: http://inquiryintoinquiry.com/2019/09/24/peirces-1870-logic-of-relatives-%e2%80%a2-overview/

My long ago encounter with Peirce's 1870 paper, "Description of a Notation for the Logic of Relatives,

Resulting from an Amplification of the Conceptions of Boole's Calculus of Logic", was one of the events

precipitating my return from the hazier heights of philosophy to the solid plains of mathematics below.

Over the years I copied out various drafts of my study notes to the web, consisting of selections from

Peirce's paper along with my running commentary. I later serialized these notes to my blog and put all

the links on an Overview page. Please see the blog post linked above for the rest of the Overview.

John Bottoms, writing in the Ontolog Forum, compared the graphic

I drew for one of Peirce's relational formulas to a pictographic

image he had been studying.

Peirce introduced the compound term "giver of a horse to a lover of a woman"

in Selection 7 to illustrate his use of marks of reference to identify the

corresponding correlates of component terms. The symbolic form of this

compound term is shown below.

In my comment on Proto-Graphical Syntax I drew lines of identity to connect

the corresponding marks of reference, as shown in the following Figure.

John tells us what he sees in this Figure in the following words:

<QUOTE>

One of my interests is in the intersection between images and prose.

The note [on Proto-Graphical Syntax] is prescient. It echoes a

semasiographic image that has been discussed recently on the web.

The image below shows two houses, and the tree shapes represent people.

In the image a girl complains to her ex-lover that his new relationship

is not useful, and he is missing an opportunity to have children with her.

This image was created by a Yukaghir girl for a local game similar to

Pictionary.

Cf: Peirce's Categories : 8

At: https://inquiryintoinquiry.com/2019/10/06/peirces-categories-%e2%80%a2-8/

When Threads Collide ...

Questions about Peirce's Categories arose in a couple of Facebook discussions,

giving me a chance to tackle a number of issues that often lead people astray.

As usual, most problems in Peirce's thought can be cleared up by duly diligent

applications of his pragmatic maxim and his relational logic working in tandem.

As one might anticipate, then, my answer to the question of Peirce's categories

has one foot already under our present head.

The best way to get clear about Peirce's categories is to look to their

origin in Aristotle's concept of a category, in effect nothing more

mysterious than a grammatical device for reducing the ambiguities

of equivocal terms. We find Peirce starting out this way in his

classification of logical terms, for instance, here:

* Peirce's 1870 "Logic Of Relatives" : Selection 1

Here's my response to a comment in the Systems Sciences Facebook Group,

questioning whether I might be comparing apples and oranges in lumping

philosophical and mathematical categories under the same head.

Scanning the spectrum of sources I sampled in my Precursors of Category Theory,

there are many differences in the categorical paradigms different observers

developed over the centuries. Just for starters, the numbers of categories

vary widely from system to system. But there is a conceptual continuity in

the "function" category markers perform in every system. If we look to the

role a category marker plays in the relation between formal expressions and

their formal objects, in effect, if we look at the matter from a semiotic

perspective, as Aristotle already did, then we see the job of a category

marker is to reduce ("drive down") the ambiguity of equivocal linguistic

expressions to the point where they obey the laws of logic.

I’m surprised to see no reference to the Supposition Logic of Peter of Spain (Petrus Hispanus) who clarified the cause of ambiguity and fallacy in Aristotle’s logic and provided a rectification that, in its requirement for an explicit ontology, is surprisingly modern.

That was just an exploratory sketch, plotting a few points on a single theme

with no plans of making an exhaustive survey. Even at that I never got time

to get back to it. I put in a pin for Kant but haven't had a chance to fill

in any excerpts. There are even "in-cite-ments" going back to my early days

reading Russell and wrestling with his take on type theory but those notions

are too hazy in my memory to make clear at present.

Helmut, All ...

There is a kind of "second cousin" kinship between category markers, tenses,

modalities, etc. In several drafts of the previous note I experimented with

grammatical terms like conjugation, declension, diacritic, inflection, etc.

to explain the function of category markers. But I eventually decided this

laid too much stress on their grammatical aspect and distracted from their

main function, which is to focus the relation between formal expressions

and formal objects.

I think it would help to clarify the sorts of formal expressions ("signs")

and formal objects (mostly "mathematical objects") I currently have in mind

to post a bit of content from an earlier discussion in several other groups.

I'll get to that after dinner ...

Different minds are drawn to Peirce for different reasons

and they tend to discover different stores of value there.

I was attracted to his work largely for his insights into

logic, math, and science and because his articulations of

their springs and catches ring true to the ways their own

practitioners understand them in practice.

One consequence is my tendency to approach the question of

categories from a particular angle, more through the logic

What follows from that approach gives me sufficient reason

My previous comment summed up my observations of a general drift toward

"absolutist and dyadic ways of thinking" in the communities of inquiry

I've known since the turn of the century. I traced its cause to "the

stubborn pull of unchecked reductionism" and a corresponding failure

to grasp the relational determinants of complex phenomena.

That last phrase gave me a lot of trouble -- I vacillated between it

and "the unchecked pull of stubborn reductionism" before flipping a coin

going with the one I wrote. To clarify, we are talking a preference for

simple models and theories which is natural enough so long as the chosen

models and theories are up to the task of explaining the phenomena, but

which becomes irrational and unnatural if it persists in the face of

steadily mounting anomalies.

That is my description and my diagnosis of present conditions

as I see them. I could be wrong about either or both. But the

reason for bringing all that up is not to raise a wail of general

lamentation. The purpose of a diagnosis is to indicate a remedy.

Re: Robert Marty ( https://list.iupui.edu/sympa/arc/peirce-l/2020-04/msg00020.html )

All,

With a few choice exceptions I have always found Peirce’s earlier writings on categories, relations, and semiotics to be

more clear, exact, and fruitful in practice than his last attempts to explain himself without the requisite logical and

mathematical supports.

Still, I like Robert Marty’s “podium” picture of the universal categories

( https://academia.edu/resource/work/41574474 ), comprehend it all or not,

and I found myself once using a similar picture to explain the relationships

among the big 3 normative sciences of aesthetics, ethics, and logic. I called

this “The Pragmatic Cosmos”, using “cosmos” in the sense of a global order.

It looks like most of this stuff has fallen off the live web but here's

Re: Robert Marty ( https://list.iupui.edu/sympa/arc/peirce-l/2020-04/msg00020.html )

All,

With a few choice exceptions I have always found Peirce’s earlier writings on categories, relations, and semiotics to be

more clear, exact, and fruitful in practice than his last attempts to explain himself without the requisite logical and

mathematical supports.

Still, I like Robert Marty’s “podium” picture of the universal categories

( https://academia.edu/resource/work/41574474 ), comprehend it all or not,

and I found myself once using a similar picture to explain the relationships

among the big 3 normative sciences of aesthetics, ethics, and logic. I called

this “The Pragmatic Cosmos”, using “cosmos” in the sense of a global order.

It looks like most of this stuff has fallen off the live web but here's

a few links I found.

Continuing with the discussion of Robert Marty's “Podium Diagram” ...

Re: Robert Marty ( https://list.iupui.edu/sympa/arc/peirce-l/2020-04/msg00047.html )

RM: What do you think of the presuppositions between the levels? Do they make sense to you?

At this point I have mostly questions, which would take further research to answer, not to mention unpacking many books

still in boxes from our move a year and a half ago, none of which I'm at liberty to do right now. So, just off the cuff ...

“Presupposition” is one of those words I tend to avoid, as it has too many uses at odds with each other. There are at

least the architectonic, causal, and logical meanings. It it were only a matter of logic, I would say “P presupposes Q”

means “P ⇒ Q”. But usually people have something more pragmatic or rhetorical in mind than pure logic would require,

something like enthymeme.

It's also common for people to confound the implication order “P ⇒ Q” with the causal order “P causes Q”, whereas it's

more like the reverse of that. In more complex settings we usually have the architectonic sense in mind, and that is

what I sensed in the case of the normative sciences. Viewed with regard to their bases, logic is a special case of

ethics and ethics is a special case of aesthetics, but with regard to their level of oversight, aesthetics must submit

to ethical control and ethics must submit to logical control.

Early on, Peirce used “involution” with the meaning it has in arithmetic or number theory, namely, “exponentiation”,

where x^y means taking x to the power of y. See the following passage and commentary.

* Peirce's 1870 Logic Of Relatives • The Sign of Involution

https://oeis.org/wiki/Peirce%27s_1870_Logic_Of_Relatives_%E2%80%A2_Part_2#Selection_12

As far as the boolean or propositional analogue goes, x^y for x, y in {0, 1 means the same thing as x ⇐ y, as one can

tell by comparing the following two operation tables.

Exponentiation and Converse Implication

https://inquiryintoinquiry.files.wordpress.com/2020/04/exponentiation-and-converse-implication.png

I haven't looked into whether Peirce uses “involution” or “involvement” with that sense in his later writings.

The Podium of the Universal Categories of C.S. Peirce

This article organizes Peirce’s universal categories and their degenerate forms from their presupposition relationships.

These relationships are formally clarified on the basis of Frege’s definition of presupposition. They are visualized

in a “podium” diagram. With these forms, we then follow step by step the well-known and very often cited third Peirce

The very strong congruence that is established between the podium and the text validates the importance, even the

necessity, of taking into account these presuppositions in order to correctly understand Peirce’s phenomenology.

A feature of particular interest to me in Robert Marty’s paper is the resonance he finds between category theory, as

it’s known in contemporary mathematics, and the study of Peirce’s Categories. I’ve long felt the cross-pollination of

these two fields was naturally bound to bear fruit. In that light I’ll refer again to the “brouillon projet” I wrote on

the Precursors of Category Theory, where I trace a common theme uniting the function of categorical paradigms from

Aristotle through Peirce to present day logic and math.

• Precursors Of Category Theory

https://oeis.org/wiki/Precursors_Of_Category_Theory

By way of orientation to the perspective I’ll adopt in reading Marty’s “Podium” paper, here’s the first of the excerpts

I collected, from a primer of category theory on the shelves of every student of the subject, giving a thumbnail

genealogy of categories from classical philosophy to current mathematics.

<QUOTE>

Now the discovery of ideas as general as these is chiefly the willingness to make a brash or speculative abstraction, in

I've been too immersed in the Peirce List discussion of Robert Marty's “Podium” paper to write much here — before I lose

Helmut Raulien asked several questions about the composition, irreducibility, and reducibility of relations. For

background on relation composition as Peirce originally treated it, I referred him to Peirce's 1870 Logic Of Relatives,

especially the section titled “The Signs for Multiplication”, along with my commentary linked below.

First I note that the formulation “3ns involves 2ns, which involves 1ns” is very dangerous [as] it forgets that 2ns has

its autonomy and 1ns too. If you look at the podium [one] remains in the inner cylinder. It seems to me that Peirce's

reproach to Hegel is:

“He has usually overlooked external Secondness, altogether. In other words, he has committed the trifling oversight of

forgetting that there is a real world with real actions and reactions. Rather a serious oversight that.”

It is therefore important to prefer “3ns involves 2ns and 1ns, while 2ns involves 1ns” which preserves the autonomy of

the Peircian categories so as not to encourage the idea of a possible peircean hegelianism.

I've been working on a comment about your first point but I'll post it … when and if I manage to put it in respectable

shape. Just by way of a hint for now, the issue turns on whether we take involves or presupposes to be a dyadic

relation and a transitive one at that, as we would if we pass from “3 involves 2” and “2 involves 1” to the conclusion

“3 involves 1”. That may be true for some concepts of involution or presupposition but I think the operative relation

in this case is a thoroughly irreducible triadic relation, one whose properties do not reduce to the composition of two

dyadic relations.

I think it will take a little more work to get clear about this.

I will go back to the draft remarks I was working on and see if

I can bring them to bear on the question.

First I note that the formulation “3ns involves 2ns, which involves 1ns” is very dangerous [as] it forgets that 2ns has

its autonomy and 1ns too. If you look at the podium [one] remains in the inner cylinder. It seems to me that Peirce's

reproach to Hegel is:

“He has usually overlooked external Secondness, altogether. In other words, he has committed the trifling oversight of

Understanding another person's thought can be difficult. Understanding the way another understands a third person's

thought, all the more so, even if that third person is not so formidable a thinker as Charles Sanders Peirce. Measures

of misunderstanding may be moderated if all thoughts and thinkers are guided by common objectives but the proof of the

pudding is in the partaking, as they say. So let's step carefully and focus on the task of determining whether category

theories, old and new, make good tools for understanding sign relations.

I do not see how we can talk here about an operative relationship that would be a triad relationship. It is not

anything other than the composition of two morphisms and I do not ask for more. 3, 2, and 1 are the “place names” and

“involves” are arrow names that I usually call alpha and beta. Now if you think about the determinations in the sign, I

have always assumed after much study of the 76 definitions, this idea that the composition of applications captures the

presence in the mind of each of the elements of the sign, in such a way that they are themselves ipso facto connected by

a triadic relationship. There is a relationship of tricoexistence that is established as in this case evoked by Peirce:

“It predicates the genuinely Triadic relationship of tricoexistence, P and Q and R coexist” (CP 2.318, unfortunately

there is a hole in my PDF of CP right after and I [left] my paper edition at the library of my university, inaccessible

at the moment).

We have a mutual incomprehension?

I don't often join the debates over sign classification so frequently animating the animadversions of the Peirce List.

As more the observer than the participant I see the same pattern over and over, with occasional hints but never any hue

of resolution fast enough to last and satisfy every dyehard.

Situations of that sort are no novelty in philosophy, or politics, or even math and science on occasion. And when they

occur it is usually because the “place to stand” from which the subject appears in its proper light has yet to be

reached by every viewer.

So I'll back up a little and say how I see things from where I am.

Robert, All ...

Let us go back to a point where paths diverged in the yarrow wood and a lot of synchronicity was lost …

Variant understandings of words like axiom, definition, predicate, proposition, proof, relation, theory, and the like

make mutual understanding difficult. For example, when I mention Peirce's definition of a sign, many people will bring

to mind a long list of short statements Peirce made in describing the properties of signs, and when I refer to Peirce's

theory of signs, many people will bring to mind the entire corpus of Peirce's writings on signs, so far as they know it,

augmented perhaps with reliable reports of statements he may have made about signs.

There are fields of study where such expansive understandings of definitions and theories are the prevailing ones,

perhaps the only feasible ones. One example would be scriptural hermeneutics, where the full sense of a word's meaning

is determined by its use in every context where it occurs. Thus the use of concordances to bring the diversity of

contextual meanings into harmony. We plow this field in a hermeneutic circle, according each bit of authoritative text

equal priority, none privileged above the other, as if equidistant from a central point radiating a pervasive message.

It's all you can do when there's nothing but the text in view.

Curiously enough, the branch of mathematical logic known as model theory sets out with an equally expansive view, taking

a maximally inclusive definition of theory as its initial point of departure and defining a theory as an arbitrary set

of sentences from a formal language. Naturally, logical and mathematical attention almost immediately shifts to more

focused spheres of theory, as indicated in the following from a standard textbook.

<QUOTE>

A set Γ of sentences is called a “theory”. A theory is said to be “closed” iff every consequence of Γ belongs to Γ. A

set Δ of sentences is said to be a “set of axioms for” a theory Γ iff Γ and \Delta have the same consequences. A theory

is called “finitely axiomatizable” iff it has a finite set of axioms. Since we may form the conjunction of a finite set

of axioms, a finitely axiomatizable theory actually always has a single axiom. The set Γ' of all consequences of Γ is

the unique closed theory which has Γ as a set of axioms.

(Chang and Keisler, p. 12).

</QUOTE>

That's all well and good as far as esoteric technical usage goes but outside those cloisters I would recommend using the

word “corpus” when we want to talk about an arbitrary set of sentences or texts and to reserve the word “theory” for

those corpora possessing more differentiated and substantial anatomies than a mere hermeneutic blastula.
