Up to this point in the discussion, we have observed that
the "number of" map 'v' : S -> R such that 'v's = [s] has
the following morphic properties:
0. [0] = 0
1. 'v'
2. x -< y => [x] =< [y]
3. [x +, y] =< [x] + [y]
contingent:
4. [xy] = [x][y]
view relation P c X x Y x Z as related to three functions:
`p_1` c
`p_3` c X x Y x Pow(Z)
f(x)
f(x+y) = f(x) + f(y)
f(p(x, y)) = q(f(x), f(y))
P(x, y, z)
(f^-1)(y)
f(z(x, y)) = z'(f(x), f(y))
Definition. f(x:y:z) = (fx:fy:fz).
f(x:y:z) = (fx:fy:
x:y:z in R => fx:fy:fz in fR

Given a set X and a subset M c X, define e_M,
the "idempotent representation" of M over X,
as the 2-adic relation e_M c X x X which is
the identity relation on M. In other words,
e_M = {<x, x> : x in M}.
Transposing this by steps into Peirce's notation:
e_M = {<x, x> : x in M}
= {x:x : x in M}
= Sum_X |x in M| x:x
'l' = "lover of ---"
's' = "servant of ---"
'l', = "lover that is --- of ---"
's', = "servant that is --- of ---"
| But not only may any absolute term be thus regarded as a relative term,
| but any relative term may in the same way be regarded as a relative with
| one correlate more. It is convenient to take this additional correlate
| as the first one.
|
| Then:
|
| 'l','s'w
|
| will denote a lover of a woman that is a servant of that woman.

Now, it's not the end of the story, of course, but it's a start.
The significant thing is what is usually the significant thing
in mathematics, at least, that two distinct descriptions refer
to the same things. Incidentally, Peirce is not really being
as indifferent to the distinctions between signs and things
as this ascii text makes him look, but uses a host of other
type-faces to distinguish the types and the uses of signs.
Discussion Notes
Discussion Note 1
GR = Gary Richmond
GR: I wonder if the necessary "elementary triad" spoken of
below isn't somehow implicated in those discussions
"invoking a 'closure principle'".
GR, quoting CSP:
| CP 1.292. It can further be said in advance, not, indeed,
| purely a priori but with the degree of apriority that is
| proper to logic, namely, as a necessary deduction from
| the fact that there are signs, that there must be an
| elementary triad. For were every element of the
| phaneron a monad or a dyad, without the relative
| of teridentity (which is, of course, a triad),
| it is evident that no triad could ever be
| built up. Now the relation of every sign
| to its object and interpretant is plainly
| a triad. A triad might be built up of
| pentads or of any higher perissad
| elements in many ways. But it
| can be proved -- and really
| with extreme simplicity,
| though the statement of
| the general proof is
| confusing -- that no
| element can have
| a higher valency
| than three.
GR: (Of course this passage also directly relates
to the recent thread on Identity and Teridentity.)
Yes, generally speaking, I think that there are deep formal principles here
that manifest themselves in these various guises: the levels of intention
or the orders of reflection, the sign relation, pragmatic conceivability,
the generative sufficiency of 3-adic relations for all practical intents,
and the irreducibility of continuous relations. I have run into themes
in combinatorics, group theory, and Lie algebras that are tantalizingly
reminiscent of the things that Peirce says here, but it will take me
some time to investigate them far enough to see what's going on.
GR: PS. I came upon the above passage last night reading through
the Peirce selections in John J. Stuhr's 'Classical American
Philosophy: Essential Readings and Interpretive Essays',
Oxford University, 1987 (the passage above is found on
pp 61-62), readily available in paperback in a new
edition, I believe.
GR: An aside: These excerpts in Sturh include versions of a fascinating
"Intellectual Autobiography", Peirce's summary of his scientific,
especially, philosophic accomplishments. I've seen them published
nowhere else.
Discussion Note 2
BU = Ben Udell
JA = Jon Awbrey
BU: I'm in the process of moving back to NYC and have had little opportunity
to do more than glance through posts during the past few weeks, but this
struck me because it sounds something I really would like to know about,
but I didn't understand it:
JA: Notice that Peirce follows the mathematician's usual practice,
then and now, of making the status of being an "individual" or
a "universal" relative to a discourse in progress. I have come
to appreciate more and more of late how radically different this
"patchwork" or "piecewise" approach to things is from the way of
some philosophers who seem to be content with nothing less than
many worlds domination, which means that they are never content
and rarely get started toward the solution of any real problem.
Just my observation, I hope you understand.
BU: "Many worlds domination", "nothing less than many worlds domination" --
as opposed to the patchwork or piecewise approach. What is many worlds
domination? When I hear "many worlds" I think of Everett's Many Worlds
interpretation of quantum mechanics.
Yes, it is a resonance of Edward, Everett, and All the Other Whos in Whoville,
but that whole microcosm is itself but the frumious reverberation of Leibniz's
Maenadolatry.
More sequitur, though, this is an issue that has simmered beneath
the surface of my consciousness for several decades now and only
periodically percolates itself over the hyper-critical thrashold
of expression. Let me see if I can a better job of it this time.
The topic is itself a patchwork of infernally recurrent patterns.
Here are a few pieces of it that I can remember arising recently:
| Zeroth Law Of Semantics
|
| Meaning is a privilege not a right.
| Not all pictures depict.
| Not all signs denote.
|
| Never confuse a property of a sign,
| for instance, existence,
| with a sign of a property,
| for instance, existence.
|
| Taking a property of a sign,
| for a sign of a property,
| is the zeroth sign of
| nominal thinking,
| and the first
| mistake.
|
| Also Sprach Zero*
A less catchy way of saying "meaning is a privilege not a right"
would most likely be "meaning is a contingency not a necessity".
But if I reflect on that phrase, it does not quite satisfy me,
since a deeper lying truth is that contingency and necessity,
connections in fact and connections beyond the reach of fact,
depend on a line of distinction that is itself drawn on the
scene of observation from the embodied, material, physical,
non-point massive, non-purely-spectrelative point of view
of an agent or community of interpretation, a discursive
universe, an engauged interpretant, a frame of at least
partial self-reverence, a hermeneutics in progress, or
a participant observer. In short, this distinction
between the contingent and the necessary is itself
contingent, which means, among other things, that
signs are always indexical at some least quantum.
Discussion Note 3
JR = Joe Ransdell
JR: Would the Kripke conception of the "rigid designator" be an instance
of the "many worlds domination"? I was struck by your speaking of
the "patchwork or piecewise" approach as well in that it seemed to
me you might be expressing the same general idea that I have usually
thought of in terms of contextualism instead: I mean the limits it
puts upon what you can say a priori if you really take contextualism
seriously, which is the same as recognizing indexicality as incapable
of elimination, I think.
Yes, I think this is the same ballpark of topics.
I can't really speak for what Kripke had in mind,
but I have a practical acquaintance with the way
that some people have been trying to put notions
like this to work on the applied ontology scene,
and it strikes me as a lot of nonsense. I love
a good parallel worlds story as much as anybody,
but it strikes me that many worlds philosophers
have the least imagination of anybody as to what
an alternative universe might really be like and
so I prefer to read more creative writers when it
comes to that. But serially, folks, I think that
the reason why some people evidently feel the need
for such outlandish schemes -- and the vast majority
of the literature on counterfactual conditionals falls
into the same spaceboat as this -- is simply that they
have failed to absorb, through the fault of Principian
filters, a quality that Peirce's logic is thoroughly
steeped in, namely, the functional interpretation
of logical terms, that is, as signs referring to
patterns of contingencies. It is why he speaks
more often, and certainly more sensibly and to
greater effect, of "conditional generals" than
of "modal subjunctives". This is also bound up
with that element of sensibility that got lost in
the transition from Peircean to Fregean quantifiers.
Peirce's apriorities are always hedged with risky bets.
Discussion Note 4
BU = Benjamin Udell
BU: I wish I had more time to ponder the "many-worlds" issue (& that my books
were not currently disappearing into heavily taped boxes). I had thought
of the piecemeal approach's opposite as the attempt to build a kind of
monolithic picture, e.g., to worry that there is not an infinite number
of particles in the physical universe for the infinity integers. But
maybe the business with rigid designators & domination of many worlds
has somehow to do with monolithism.
Yes, that's another way of saying it. When I look to my own priorities,
my big worry is that logic as a discipline is not fulfilling its promise.
I have worked in too many settings where the qualitative researchers and
the quantitative researchers could barely even talk to one an Other with
any understanding, and this I recognized as a big block to inquiry since
our first notice of salient facts and significant phenomena is usually
in logical, natural language, or qualitative forms, while our eventual
success in resolving anomalies and solving practical problems depends
on our ability to formalize, operationalize, and quantify the issues,
even if only to a very partial degree, as it generally turns out.
When I look to the history of how logic has been deployed in mathematics,
and through those media in science generally, it seems to me that the
Piece Train started to go off track with the 'Principia Mathematica'.
All pokes in the rib aside, however, I tend to regard this event
more as the symptom of a localized cultural phenomenon than as
the root cause of the broader malaise.
Discussion Note 5
CG = Clark Goble
JA = Jon Awbrey
JA, quoting CSP:
| For example,
|
| f + u
|
| means all Frenchmen besides all violinists, and,
| therefore, considered as a logical term, implies
| that all French violinists are 'besides themselves'.
CG: Could you clarify your use of "besides"?
CG: I think I am following your thinking in that you
don't want the logical terms to be considered
to have any necessary identity between them.
Is that right?
I use vertical sidebars "|" for long quotations, so this
is me quoting Peirce at CP 3.67 who is explaining in an
idiomatic way Boole's use of the plus sign for a logical
operation that is strictly speaking limited to terms for
mutually exclusive classes. The operation would normally
be extended to signify the "symmetric difference" operator.
But Peirce is saying that he prefers to use the sign "+,"
for inclusive disjunction, corresponding to the union of
the associated classes. Peirce calls Boole's operation
"invertible" because it amounts to the sum operation in
a field, whereas the inclusive disjunction or union is
"non-invertible", since knowing that A |_| B = C does
not allow one to say determinately that A = C - B.
I can't recall if Boole uses this 'besides' idiom,
but will check later.
Discussion Note 6
CG = Clark Goble
JA = Jon Awbrey
JA: I use vertical sidebars "|" for long quotations, so this
is me quoting Peirce at CP 3.67 who is explaining in an
idiomatic way Boole's use of the plus sign for a logical
operation that is strictly speaking limited to terms for
mutually exclusive classes.
CG: Is that essay related to any of the essays
in the two volume 'Essential Peirce'? I'm
rather interested in how he speaks there.
No, the EP volumes are extremely weak on logical selections.
I see nothing there that deals with the logic of relatives.
JA: But Peirce is saying that he prefers to use the sign "+,"
for inclusive disjunction, corresponding to the union of
the associated classes.
CG: The reason I asked was more because it seemed
somewhat interesting in light of the logic of
operators in quantum mechanics. I was curious
if the use of "beside" might relate to that.
But from what you say it probably was just me
reading too much into the quote. The issue of
significance was whether the operation entailed
the necessity of mutual exclusivity or whether
some relationship between the classes might be
possible. I kind of latched on to Peirce's
odd statement about "all French violinists
are 'beside themselves'".
CG: Did Peirce have anything to say about
what we'd call non-commuting operators?
In general, 2-adic relative terms are non-commutative.
For example, a brother of a mother is not identical to
a mother of a brother.
Discussion Note 7
GR = Gary Richmond
GR: I am very much enjoying, which is to say,
learning from your interlacing commentary
on Peirce's 1870 "Logic of Relatives" paper.
GR: What an extraordinary paper the 1870 "LOG" is! Your notes helped
me appreciate the importance of the unanticipated proposal of P's
to "assign to all logical terms, numbers". On the other hand,
the excerpts suggested to we why Peirce finally framed his
Logic of Relatives into graphical form. Still, I think
that a thorough examination of the 1970 paper might
serve as propaedeutic (and of course, much more)
for the study of the alpha and beta graphs.
Yes, there's gold in them thar early logic papers that has been "panned"
but nowhere near mined in depth yet. The whole quiver of arrows between
terms and numbers harks back to the 'numeri characteristici' of Leibniz,
of course, but Leibniz attended more on the intensional chains of being
while Peirce will here start to "escavate" the extensional hierarchies.
I consider myself rewarded that you see the incipient impulse toward
logical graphs, as one of the most striking things to me about this
paper is to see these precursory seeds already planted here within
it and yet to know how long it will take them to sprout and bloom.
Peirce is obviously struggling to stay within the linotyper's art --
a thing that we, for all our exorbitant hype about markable text,
are still curiously saddled with -- but I do not believe that it
is possible for any mind equipped with a geometrical imagination
to entertain these schemes for connecting up terminological hubs
with their terminological terminals without perforce stretching
imaginary strings between the imaginary gumdrops.
GR: I must say though that the pace at which you've been throwing this at us
is not to be kept up with by anyone I know "in person or by reputation".
I took notes on the first 5 or 6 Notes, but can now just barely find
time to read through your posts.
Oh, I was trying to burrow as fast as I could toward the more untapped veins --
I am guessing that things will probably "descalate" a bit over the next week,
but then, so will our attention spans ...
Speaking of which, I will have to break here, and pick up the rest later ...
Discussion Note 8
GR = Gary Richmond
GR: In any event, I wish that you'd comment on Note 5 more directly (though
you do obliquely in your own diagramming of "every [US] Vice-President(s) ...
[who is] every President(s) of the US Senate".
There are several layers of things to say about that,
and I think that it would be better to illustrate the
issues by way of the examples that Peirce will soon be
getting to, but I will see what I can speak to for now.
GR: But what interested me even more in LOR, Note 5, was the sign < ("less than"
joined to the sign of identity = to yield P's famous sign -< (or more clearly,
=<) of inference, which combines the two (so that -< (literally, "as small as")
means "is". I must say I both "get" this and don't quite (Peirce's example(s) of
the frenchman helped a little). Perhaps your considerably more mathematical mind
can help clarify this for a non-mathematician such as myself. (My sense is that
"as small as" narrows the terms so that "everything that occurs in the conclusion
is already contained in the premise.) I hope I'm not being obtuse here. I'm sure
it's "all too simple for words".
Then let us draw a picture.
"(F (G))", read "not F without G", means that F (G), that is, F and not G,
is the only region exempted from the occupation of being in this universe:

So, "(F (G))", "F => G", "F =< G", "F -< G", "F c G",
under suitable mutations of interpretation, are just
so many ways of saying that the denotation of "F" is
contained within the denotation of "G".
Now, let us look to the "characteristic functions" or "indicator functions"
of the various regions of being. It is frequently convenient to ab-use the
same letters for them and merely keep a variant interpretation "en thy meme",
but let us be more meticulous here, and reserve the corresponding lower case
letters "f" and "g" to denote the indicator functions of the regions F and G,
respectively.
Taking B = {0, 1} as the boolean domain, we have:
f, g : X -> B
(f^(-1))(1) = F
(g^(-1))(1) = G
In general, for h : X -> B, an expression like "(h^(-1))(1)"
can be read as "the inverse of h evaluated at 1", in effect,
denoting the set of points in X where h evaluates to "true".
This is called the "fiber of truth" in h, and I have gotten
where I like to abbreviate it as "[|h|]".
Accordingly, we have:
F = [|f|] = (f^(-1))(1) c X
G = [|g|] = (g^(-1))(1) c X
This brings us to the question, what sort
of "functional equation" between f and g
goes with the regional constraint (F (G))?
Just this, that f(x) =< g(x) for all x in X,
where the '=<' relation on the values in B
has the following operational table for
the pairing "row head =< column head".
o---------o---------o---------o
| =< # 0 | 1 |
o=========o=========o=========o
| 0 # 1 | 1 |
o---------o---------o---------o
| 1 # 0 | 1 |
o---------o---------o---------o
And this, of course, is the same thing as the truth table
for the conditional connective or the implication relation.
GR: By the way, in the semiosis implied by the modal gamma graphs,
could -< (were it used there, which of course it is not) ever
be taken to mean,"leads to" or "becomes" or "evolves into"?
I informally use it that way myself, using the ordinary
arrow for implication.
I am a bit insensitive to the need for modal logic,
since necessity in mathematics always seems to come
down to being a matter of truth for all actual cases,
if under an expanded sense of actuality that makes it
indiscernible from possibility, so I must beg off here.
But there are places where Peirce makes a big deal about
the advisability of drawing the '-<' symbol in one fell
stroke of the pen, kind of like a "lazy gamma" -- an old
texican cattle brand -- and I have seen another place where
he reads "A -< B" as "A, in every way that it can be, is B",
as if this '-<' fork in the road led into a veritable garden
of branching paths.
And out again ...

JA: I am a bit insensitive to the need for modal logic,
since necessity in mathematics always seems to come
down to being a matter of truth for all actual cases,
if under an expanded sense of actuality that makes it
indiscernible from possibility, so I must beg off here.
GR: I cannot agree with you regarding modal logic. Personally
I feel that the gamma part of the EG's is of the greatest
interest and potential importance, and as Jay Zeman has
made clear in his dissertation, Peirce certainly thought
this as well.
You disagree that I am insensitive? Well, certainly nobody has ever done that before!
No, I phrased it that way to emphasize the circumstance that it ever hardly comes up
as an issue within the limited purview of my experience, and when it does -- as in
topo-logical boundary situations -- it seems to require a sort of analysis that
doesn't comport all that well with the classical modes and natural figures of
speech about it. Then again, I spent thirty years trying to motorize Alpha,
have only a few good clues how I would go about Beta, and so Gamma doesn't
look like one of those items on my plate.

Discussion Note 10
BM = Bernard Morand
JA = Jon Awbrey
BM: Thanks for your very informative talk. There
is a point that I did not understand in note 35:
JA: If we operate in accordance with Peirce's example of `g`'o'h
as the "giver of a horse to an owner of that horse", then we
may assume that the associative law and the distributive law
are by default in force, allowing us to derive this equation:
JA: 'l','s'w = 'l','s'(B +, D +, E) = 'l','s'B +, 'l','s'D +, 'l','s'E
BM: May be because language or more probably my lack of training in logic, what
does mean that "associative law and distributive law are by default in force"?
Those were some tricky Peirces,
and I was trying to dodge them
as artful as could be, but now
you have fastly apprehended me!
It may be partly that I left out the initial sections of this paper where Peirce
discusses how he will regard the ordinarily applicable principles in the process
of trying to extend and generalize them (CP 3.45-62), but there may be also an
ambiguity in Peirce's use of the phrase "absolute conditions" (CP 3.62-68).
Does he mean "absolutely necessary", "indispensable", "inviolate", or
does he mean "the conditions applying to the logic of absolute terms",
in which latter case we would expect to alter them sooner or later?
We lose the commutative law, xy = yx, as soon as we extend to 2-adic relations,
but keep the associative law, x(yz) = (xy)z, as the multiplication of 2-adics
is the logical analogue of ordinary matrix multiplication, and Peirce like
most mathematicians treats the double distributive law, x(y + z) = xy + xz
and (x + y)z = xz + yz, and as something that must be striven to preserve
as far as possible.
Strictly speaking, Peirce is already using a principle that goes beyond
the ordinary associative law, but that is recognizably analogous to it,
for example, in the modified Othello case, where (J:J:D)(J:D)(D) = J.
If it were strictly associative, then we would have the following:
1. (J:J:D)((J:D)(D)) = (J:J:D)(J) = 0?
2. ((J:J:D)(J:D))(D) = (J)(D) = 0?
In other words, the intended relational linkage would be broken.
However, the type of product that Peirce is taking for granted
in this situation often occurs in mathematics in just this way.
There is another location where he comments more fully on this,
but I have the sense that it was a late retrospective remark,
and I do not recall if it was in CP or in the microfilm MS's
that I read it.
By "default" conditions I am referring more or less to what
Peirce says at the end of CP 3.69, where he use an argument
based on the distributive principle to rationalize the idea
that 'A term multiplied by two relatives shows that the same
individual is in the two relations'. This means, for example,
that one can let "`g`'o'h", without subjacent marks or numbers,
be interpreted on the default convention of "overlapping scopes",
where the two correlates of `g` are given by the next two terms
in line, namely, 'o' and h, and the single correlate of 'o' is
given by the very next term in line, namely, h. Thus, it is
only when this natural scoping cannot convey the intended
sense that we have to use more explicit mark-up devices.
BM: About another point: do you think that the LOR could be of some help to solve
the puzzle of the "second way of dividing signs" where CSP concludes that 66
classes could be made out of the 10 divisions (Letters to lady Welby)?
(As I see them, the ten divisions involve a mix of relative terms,
dyadic relations and a triadic one. In order to make 66 classes
it is clear that these 10 divisions have to be stated under some
linear order. The nature of this order is at the bottom of the
disagreements on the subject).
This topic requires a longer excuse from me
than I am able to make right now, but maybe
I'll get back to it later today or tomorrow.

Yes. At any rate, I have a pretty clear sense from reading Peirce's work
in the period 1865-1870 that the need to understand the function of signs
in scientific inquiry is one of the main reasons he found himself forced
to develop both the theory of information and the logic of relatives.
Peirce's work of this period is evenly distributed across the extensional
and intensional pans of the balance in a way that is very difficult for us
to follow anymore. I remember when I started looking into this I thought of
myself as more of an "intensional, synthetic" than an "extensional, analytic"
type of thinker, but that seems like a long time ago, as it soon became clear
that much less work had been done in the Peirce community on the extensional
side of things, while that was the very facet that needed to be polished up
in order to reconnect logic with empirical research and mathematical models.
So I fear that I must be content that other able people are working on the
intensional classification of sign relations.
Still, the way that you pose the question is very enticing,
so maybe it is time for me to start thinking about this
aspect of sign relations again, if you could say more
about it.
Discussion Note 12
BM = Bernard Morand
BM: The pairing "intensional, synthetic" against the other "extensional, analytic"
is not one that I would have thought so. I would have paired synthetic with
extensional because synthesis consists in adding new facts to an already made
conception. On the other side analysis looks to be the determination of
features while neglecting facts. But may be there is something like
a symmetry effect leading to the same view from two different points.
Oh, it's not too important, as I don't put a lot of faith in such divisions,
and the problem for me is always how to integrate the facets of the object,
or the faculties of the mind -- but there I go being synthetic again!
I was only thinking of a conventional contrast that used to be drawn
between different styles of thinking in mathematics, typically one
points to Descartes, and the extensionality of analytic geometry,
versus Desargues, and the intensionality of synthetic geometry.
It may appear that one has side-stepped the issue of empiricism
that way, but then all that stuff about the synthetic a priori
raises its head, and we have Peirce's insight that mathematics
is observational and even experimental, and so I must trail off
into uncoordinated elliptical thoughts ...
The rest I have to work at a while, and maybe go back to the Welby letters.
Discussion Note 13
BM = Bernard Morand
BM: I will try to make clear the matter, at least as far as I understand it
for now. We can summarize in a table the 10 divisions with their number
in a first column, their title in current (peircean) language in the second
and some kind of logical notation in the third. The sources come mainly from
the letters to Lady Welby. While the titles come from CP 8.344, the third column
comes from my own interpretation.
BM: So we get:
I - According to the Mode of Apprehension of the Sign itself - S
II - According to the Mode of Presentation of the Immediate Object - Oi
III - According to the Mode of Being of the Dynamical Object - Od
IV - According to the Relation of the Sign to its Dynamical Object - S-Od
V - According to the Mode of Presentation of the Immediate Interpretant - Ii
VI - According to the Mode of Being of the Dynamical Interpretant - Id
VII - According to the relation of the Sign to the Dynamical Interpretant - S-Id
VIII - According to the Nature of the Normal Interpretant - If
IX - According to the the relation of the Sign to the Normal Interpretant - S-If
X - According to the Triadic Relation of the Sign to its Dynamical Object
and to its Normal Interpretant - S-Od-If
For my future study, I will reformat the table in a way that I can muse upon.
I hope the roman numerals have not become canonical, as I cannot abide them.

[Table. Ten Divisions of Signs (Peirce, Morand)]
BM: Yes this is clearer (in particular in expressing relations with :)
This is what Peirce used to form elementary relatives, for example,
o:s:i = <o, s, i>, and I find it utterly ubertous in a wide variety
of syntactic circumstances.
BM: I suggest making a correction to myself if
the table is destinate to become canonic.
Hah! Good one!
BM: I probably made a too quick jump from Normal Interpretant to Final Interpretant.
As we know, the final interpretant, the ultimate one is not a sign for Peirce
but a habit. So for the sake of things to come it would be more careful to
retain I_n in place of I_f for now.
This accords with my understanding of how the word is used in mathematics.
In my own work it has been necessary to distinguish many different species
of expressions along somewhat similar lines, for example: arbitrary, basic,
canonical, decidable, normal, periodic, persistent, prototypical, recurrent,
representative, stable, typical, and so on. So I will make the changes below:

Discussion Note 15
I will need to go back and pick up the broader contexts of your quotes. For ease of study I break Peirce's long paragraphs into smaller pieces. | It seems to me that one of the first useful steps toward a science | of 'semeiotic' ([Greek 'semeiootike']), or the cenoscopic science | of signs, must be the accurate definition, or logical analysis, | of the concepts of the science. | | I define a 'Sign' as anything which on the one hand | is so determined by an Object and on the other hand | so determines an idea in a person's mind, that this | latter determination, which I term the 'Interpretant' | of the sign, is thereby mediately determined by that | Object. | | A sign, therefore, has a triadic relation to | its Object and to its Interpretant. But it is | necessary to distinguish the 'Immediate Object', | or the Object as the Sign represents it, from | the 'Dynamical Object', or really efficient | but not immediately present Object. | | It is likewise requisite to distinguish | the 'Immediate Interpretant', i.e. the | Interpretant represented or signified in | the Sign, from the 'Dynamic Interpretant', | or effect actually produced on the mind | by the Sign; and both of these from | the 'Normal Interpretant', or effect | that would be produced on the mind by | the Sign after sufficient development | of thought. | | On these considerations I base a recognition of ten respects in which Signs | may be divided. I do not say that these divisions are enough. But since | every one of them turns out to be a trichotomy, it follows that in order | to decide what classes of signs result from them, I have 3^10, or 59049, | difficult questions to carefully consider; and therefore I will not | undertake to carry my systematical division of signs any further, | but will leave that for future explorers. | | C.S. Peirce, 'Collected Papers', CP 8.343. You never know when the future explorer will be yourself.
Discussion Note 16
Burks, the editor of CP 8, attaches this footnote to CP 8.342-379, "On the Classification of Signs": | From a partial draft of a letter to Lady Welby, bearing | the dates of 24, 25, and 28 December 1908, Widener IB3a, | with an added quotation in 368n23. ... There is a passage roughly comparable to CP 8.343 in a letter to Lady Welby dated 23 December 1908, pages 397-409 in Wiener, which is incidentally the notorious "sop to Cerberus" letter: | It is usual and proper to distinguish two Objects of a Sign, | the Mediate without, and the Immediate within the Sign. Its | Interpretant is all that the Sign conveys: acquaintance with | its Object must be gained by collateral experience. | | The Mediate Object is the Object outside of the Sign; I call | it the 'Dynamoid' Object. The Sign must indicate it by a hint; | and this hint, or its substance, is the 'Immediate' Object. | | Each of these two Objects may be said to be capable of either of | the three Modalities, though in the case of the Immediate Object, | this is not quite literally true. | | Accordingly, the Dynamoid Object may be a Possible; when I term | the Sign an 'Abstractive'; such as the word Beauty; and it will be | none the less an Abstractive if I speak of "the Beautiful", since it is | the ultimate reference, and not the grammatical form, that makes the sign | an 'Abstractive'. | | When the Dynamoid Object is an Occurrence (Existent thing or Actual fact | of past or future), I term the Sign a 'Concretive'; any one barometer | is an example; and so is a written narrative of any series of events. | | For a 'Sign' whose Dynamoid Object is a Necessitant, I have at present | no better designation than a 'Collective', which is not quite so bad a | name as it sounds to be until one studies the matter: but for a person, | like me, who thinks in quite a different system of symbols to words, it | is so awkward and often puzzling to translate one's thought into words! | | If the Immediate Object is a "Possible", that is, if the Dynamoid Object | is indicated (always more or less vaguely) by means of its Qualities, etc., | I call the Sign a 'Descriptive'; | | if the Immediate is an Occurrence, I call the Sign a 'Designative'; | | and if the Immediate Object is a Necessitant, I call the Sign a | 'Copulant'; for in that case the Object has to be so identified | by the Interpreter that the Sign may represent a necessitation. | My name is certainly a temporary expedient. | | It is evident that a possible can determine nothing but a Possible, | it is equally so that a Necessitant can be determined by nothing but | a Necessitant. Hence it follows from the Definition of a Sign that | since the Dynamoid Object determines the Immediate Object, | | Which determines the Sign itself, | which determines the Destinate Interpretant | which determines the Effective Interpretant | which determines the Explicit Interpretant | | the six trichotomies, instead of determining 729 classes of signs, | as they would if they were independent, only yield 28 classes; | and if, as I strongly opine (not to say almost prove), there | are four other trichotomies of signs of the same order of | importance, instead of making 59,049 classes, these will | only come to 66. | | The additional 4 trichotomies are undoubtedly, first: | | Icons*, Symbols, Indices, | |*(or Simulacra, Aristotle's 'homoiomata'), caught from Plato, who I guess took it | from the Mathematical school of logic, for it earliest appears in the 'Phaedrus' | which marks the beginning of Plato's being decisively influenced by that school. | Lutoslowski is right in saying that the 'Phaedrus' is later than the 'Republic' | but his date 379 B.C. is about eight years too early. | | and then 3 referring to the Interpretants. One of these I am pretty confident | is into: 'Suggestives', 'Imperatives', 'Indicatives', where the Imperatives | include the Interrogatives. Of the other two I 'think' that one must be | into Signs assuring their Interpretants by: | | Instinct, Experience, Form. | | The other I suppose to be what, in my 'Monist' | exposition of Existential Graphs, I called: | | Semes, Phemes, Delomes. | | CSP, 'Selected Writings', pp. 406-408. | |'Charles S.

JA: In closing, observe that the teridentity relation has turned up again
in this context, as the second comma-ing of the universal term itself:
1,, = B:B:B +, C:C:C +, D:D:D +, E:E:E +, I:I:I +, J:J:J +, O:O:O.
HC: I see that you've come around to a mention of teridentity again, Jon.
Still, if I recall the prior discussions, then no one doubts that we
can have a system of notation in which teridentity appears (I don't
actually see it here).
Perhaps we could get at the root of the misunderstanding
if you tell me why you don't actually see the concept of
teridentity being exemplified here.
If it's only a matter of having lost the context of the
present discussion over the break, then you may find the
previous notes archived at the distal ends of the ur-links
that I append below (except for the first nine discussion
notes that got lost in a disk crash at the Arisbe Dev site).
HC: Also, I think we can have a system of notation in which
teridentity is needed. Those points seem reasonably clear.
The advantage of a concept is the integration of a species of manifold.
The necessity of a concept is the incapacity to integrate it otherwise.
Of course, no one should be too impressed with a concept that
is only the artifact of a particular system of representation.
So before we accord a concept the status of addressing reality,
and declare it a term of some tenured office in our intellects,
we would want to see some evidence that it helps us to manage
a reality that we cannot see a way to manage any other way.
Granted.
Now how in general do we go about an investiture of this sort?
That is the big question that would serve us well to consider
in the process of the more limited investigation of identity.
Indeed, I do not see how it is possible to answer the small
question if no understanding is reached on the big question.
HC: What remains relatively unclear is why we should need a system of notation
in which teridentity appears or is needed as against one in which it seems
not to be needed -- since assertion of identity can be made for any number
of terms in the standard predicate calculus.
This sort of statement totally non-plusses me.
It seems like a complete non-sequitur or even
a contradiction in terms to me.
The question is about the minimal adequate resource base for
defining, deriving, or generating all of the concepts that we
need for a given but very general type of application that we
conventionally but equivocally refer to as "logic". You seem
to be saying something like this: We don't need 3-identity
because we have 4-identity, 5-identity, 6-identity, ..., in
the "standard predicate calculus". The question is not what
concepts are generated in all the generations that follow the
establishment of the conceptual resource base (axiom system),
but what is the minimal set of concepts that we can use to
generate the needed collection of concepts. And there the
answer is, in a way that is subject to the usual sorts of
mathematical proof, that 3-identity is the minimum while
2-identity is not big enough to do the job we want to do.

I only have the CP 8 and Wiener versions here, so I will

BM: I made such a kind of comparison some time ago. I selected
the following 3 cases on the criterium of alternate "grounds".
Hoping it could save some labor. The first rank expressions
come from the MS 339 written in Oct. 1904 and I label them
with an (a). I think that it is interesting to note that
they were written four years before the letters to Welby
and just one or two years after the Syllabus which is the
usual reference for the classification in 3 trichotomies
and 10 classes. The second (b) is our initial table (from
a draft to Lady Welby, Dec. 1908, CP 8.344) and the third
(c) comes from a letter sent in Dec. 1908 (CP 8.345-8.376).
A tabular presentation would be better but I can't do it.
Comparing (c) against (a) and (b) is informative, I think.
Is this anywhere that it can be linked to from Arisbe?

| C.S. Peirce, 'Collected Papers', CP 8.343.
JA: Well, you've really tossed me in the middle of the briar patch now!
I must continue with my reading from the 1870 LOR, ...
BM: Yes indeed! I am irritated by having not the necessary
turn of mind to fully grasp it. But it seems to be a
prerequisite in order to understand the very meaning
of the above table. It could be the same for:
BM, quoting CSP:
| I define a 'Sign' as anything which on the one hand
| is so determined by an Object and on the other hand
| so determines an idea in a person's mind, that this
| latter determination, which I term the 'Interpretant'
| of the sign, is thereby mediately determined by that
| Object.
BM: The so-called "latter determination" would make the 'Interpretant'
a tri-relative term into a teridentity involving Sign and Object.
Isn't it?
BM: I thought previously that the Peirce's phrasing was just applying the
principle of transitivity. From O determines S and S determines I,
it follows: O determines I. But this is not the same as teridentity.
Do you think so or otherwise?
My answers are "No" and "Otherwise".
Continuing to discourse about definite universes thereof,
the 3-identity term over the universe 1 = {A, B, C, D, ...} --
I only said it was definite, I didn't say it wasn't vague! --
designates, roughly speaking, the 3-adic relation that may
be hinted at by way of the following series:
1,, = A:A:A +, B:B:B +, C:C:C +, D:D:D +, ...
I did a study on Peirce's notion of "determination".
As I understand it so far, we need to keep in mind
that it is more fundamental than causation, can be
a form of "partial determination", and is roughly
formal, mathematical, or "information-theoretic",
not of necessity invoking any temporal order.
For example, when we say "The points A and B determine the line AB",
this invokes the concept of a 3-adic relation of determination that
does not identify A, B, AB, is not transitive, as transitivity has
to do with the composition of 2-adic relations and would amount to
the consideration of a degenerate 3-adic relation in this context.
Now, it is possible to have a sign relation q whose sum enlists
an elementary sign relation O:S:I where O = S = I. For example,
it makes perfect sense to me to say that the whole universe may
be a sign of itself to itself, so the conception is admissable.
But this amounts to a very special case, by no means general.
More generally, we are contemplating sums like the following:
q = O1:S1:I1 +, O2:S2:I2 +, O3:S3:I3 +, ...

HC: Though I certainly hesitate to think that we are separated
from the world by a veil of signs, it seems clear, too, on
Peircean grounds, that no sign can ever capture its object

JR: Any case of self-representation is a case of sign-object identity,
in some sense of "identity". I have argued in various places that
this is the key to the doctrine of immediate perception as it occurs
in Peirce's theory.

AS: We are not separated from the world by a veil of signs nor we are a veil of signs.
Simply we are signs.
AS, quoting CSP:
| The *man-sign* acquires information, and comes to mean more than he did before.
| But so do words. Does not electricity mean more now than it did in the days
| of Franklin? Man makes the word, and the word means nothing which the man
| has not made it mean, and that only to some man. But since man can think
| only by means of words or other external symbols, these might turn round
| and say: "You mean nothing which we have not taught you, and then only
| so far as you address some word as the interpretant of your thought".
| In fact, therefore, men and words reciprocally educate each other;
| each increase of a man's information involves, and is involved by,
| a corresponding increase of a word's information.
|
| Without fatiguing the reader by stretching this parallelism too far, it is
| sufficient to say that there is no element whatever of man's consciousness
| which has not something corresponding to it in the word; and the reason is
| obvious. It is that the word or sign which man uses *is* the man itself.
| For, as the fact that every thought is a sign, taken in conjunction with
| the fact that life is a train of thought, proves that man is a sign; so,
| that every thought is an *external* sign proves that man is an external
| sign. That is to say, the man and the external sign are identical, in
| the same sense in which the words 'homo' and 'man' are identical. Thus
| my language is the sum total of myself; for the man is the thought ...

mathematical proof, that 3-identity is the minimum while
2-identity is not big enough to do the job we want to do.
HC: I have fallen a bit behind on this thread while attending to some other
matters, but in this reply, you do seem to me to be coming around to an
understanding of the issues involved, as I see them. You put the matter
this way, "We don't need 3-identity because we have 4-identity, 5-identity,
6-identity, ..., in the 'standard predicate calculus'". Actually, as I think
you must know, there is no such thing as "4-identity", "5-identity", etc., in
the standard predicate calculus. It is more that such concepts are not needed,
just as teridentity is not needed, since the general apparatus of the predicate
calculus allows us to express identity among any number of terms without special
provision beyond "=".
No, that is not the case. Standard predicate calculus allows the expression
of predicates I_k, for k = 2, 3, 4, ..., such that I_k (x_1, ..., x_k) holds
if and only if all x_j, for j = 1 to k, are identical. So predicate calculus
contains a k-identity predicate for all such k. So whether "they're in there"
is not an issue. The question is whether these or any other predicates can be
constructed or defined in terms of 2-adic relations alone. And the answer is
no, they cannot. The vector of the misconception counterwise appears to be
as various a virus as the common cold, and every bit as resistant to cure.
I have taken the trouble to enumerate some of the more prevalent strains,
but most of them appear to go back to the 'Principia Mathematica', and
the variety of nominalism called "syntacticism" -- Ges-und-heit! --
that was spread by it, however unwittedly by some of its carriers.
Discussion Note 23
In trying to answer the rest of your last note, it seems that we cannot go any further without achieving some concrete clarity as to what is denominated by "standard predicate calculus", that is, "first order logic", or whatever. There is a "canonical" presentation of the subject, as I remember it, anyway, in the following sample of materials from Chang & Keisler's 'Model Theory'. (There's a newer edition of the book, but this part of the subject hasn't really changed all that much in ages.) Model Theory 01-39

HC: I might object that "teridentity" seems to come
to a matter of "a=b & b=c", so that a specific
predicate of teridentity seems unnecessary.
I am presently concerned with expositing and interpreting
the logical system that Peirce laid out in the LOR of 1870.
It is my considered opinion after thirty years of study that
there are untapped resources remaining in this work that have
yet to make it through the filters of that ilk of syntacticism
that was all the rage in the late great 1900's. I find there
to be an appreciably different point of view on logic that is
embodied in Peirce's work, and until we have made the minimal
effort to read what he wrote it is just plain futile to keep
on pretending that we have already assimilated it, or that
we are qualified to evaluate its cogency.
The symbol "&" that you employ above denotes a mathematical object that
qualifies as a 3-adic relation. Independently of my own views, there
is an abundance of statements in evidence that mathematical thinkers
from Peirce to Goedel consider the appreciation of facts like this
to mark the boundary between realism and nominalism in regard to
mathematical objects.

HC: I would agree, I think, that "&" may be thought of
as a function mapping pairs of statements onto the
conjunction of that pair.
Yes, indeed, in the immortal words of my very first college algebra book:
"A binary operation is a ternary relation". As it happens, the symbol "&"
is equivocal in its interpretation -- computerese today steals a Freudian
line and dubs it "polymorphous" -- it can be regarded in various contexts
as a 3-adic relation on syntactic elements called "sentences", on logical
elements called "propositions", or on truth values collated in the boolean
domain B = {false, true} = {0, 1}. But the mappings and relations between
all of these interpretive choices are moderately well understood. Still,
no matter how many ways you enumerate for looking at a B-bird, the "&" is
always 3-adic. And that is sufficient to meet your objection, so I think
I will just leave it there until next time.
On a related note, that I must postpone until later:
We seem to congrue that there is a skewness between
the way that most mathematicians use logic and some
philosophers talk about logic, but I may not be the
one to set it adjoint, much as I am inclined to try.
At the moment I have this long-post-poned exponency
to carry out. I will simply recommend for your due
consideration Peirce's 1870 Logic Of Relatives, and
leave it at that. There's a cornucopiousness to it
that's yet to be dreamt of in the philosophy of the
1900's. I am doing what I can to infotain you with
the Gardens of Mathematical Recreations that I find
within Peirce's work, and that's in direct response
to many, okay, a couple of requests. Perhaps I can
not hope to attain the degree of horticultural arts
that Gardners before me have exhibited in this work,
but then again, who could? Everybody's a critic --
but the better ones read first, and criticize later.
Discussion Note 26
HC = Howard Callaway
HC: But on the other hand, it is not customary to think of "&" as
a relation among statements or sentences -- as, for instance,
logical implication is considered a logical relation between
statements or sentences.
Actually, it is the custom in many quarters to treat all of the
boolean operations, logical connectives, propositional relations,
or whatever you want to call them, as "equal citizens", having each
their "functional" (f : B^k -> B) and their "relational" (L c B^(k+1))
interpretations and applications. From this vantage, the interpretive
distinction that is commonly regarded as that between "assertion" and
mere "contemplation" is tantamount to a "pragmatic" difference between
computing the values of a function on a given domain of arguments and
computing the inverse of a function vis-a-vis a prospective true value.
This is the logical analogue of the way that our mathematical models
of reality have long been working, unsuspected and undisturbed by
most philosophers of science, I might add. If only the logical
side of the ledger were to be developed rather more fully than
it is at present, we might wake one of these days to find our
logical accounts of reality, finally, at long last, after an
overweaningly longish adolescence, beginning to come of age.
Discussion Note 27
HC = Howard Callaway
HC: For, if I make an assertion A&B, then I am not asserting
that the statement A stands in a relation to a statement B.
Instead, I am asserting the conjunction A&B (which logically
implies both the conjuncts in view of the definition of "&").
Please try to remember where we came in. This whole play of
animadversions about 3-adicity and 3-identity is set against
the backdrop of a single point, over the issue as to whether
3-adic relations are wholly dispensable or somehow essential
to logic, mathematics, and indeed to argument, communication,
and reasoning in general. Some folks clamor "Off with their
unnecessary heads!" -- other people, who are forced by their
occupations to pay close attention to the ongoing complexity
of the processes at stake, know that, far from finding 3-ads
in this or that isolated corner of the realm, one can hardly
do anything at all in the ways of logging or mathing without
running smack dab into veritable hosts of them.
I have just shown that "a=b & b=c" involves a 3-adic relation.
Some people would consider this particular 3-adic relation to
be more complex than the 3-identity relation, but that may be
a question of taste. At any rate, the 3-adic aspect persists.
HC: If "&" counts as a triadic relation, simply because it serves
to conjoin two statements into a third, then it would seem that
any binary relation 'R' will count as triadic, simply because
it places two things into a relation, which is a "third" thing.
By the same kind of reasoning a triadic relation, as ordinarily
understood would be really 4-adic.
The rest of your comments are just confused,
and do not use the terms as they are defined.
Discussion Note 28
JA = Jon Awbrey
JR = Joseph Ransdell
JA: Notice that Peirce follows the mathematician's usual practice,
then and now, of making the status of being an "individual" or
a "universal" relative to a discourse in progress. I have come
to appreciate more and more of late how radically different this
"patchwork" or "piecewise" approach to things is from the way of
some philosophers who seem to be content with nothing less than
many worlds domination, which means that they are never content
and rarely get started toward the solution of any real problem.
Just my observation, I hope you understand.
JR: Yes, I take this as underscoring and explicating the import of
making logic prior to rather than dependent upon metaphysics.
I think that Peirce, and of course many math folks, would take math
as prior, on a par, or even identical with logic. Myself I've been
of many minds about this over the years. The succinctest picture
that I get from Peirce is always this one:
| [Riddle of the Sphynx]
|
| Normative science rests largely on phenomenology and on mathematics;
| Metaphysics on phenomenology and on normative science.
|
| C.S. Peirce, CP 1.186 (1903)
|
|
| o Metaphysics

| / \ |
| / \ |

| Mathematics o o Phenomenology
|
|
| ROTS. http://stderr.org/pipermail/inquiry/2004-March/001262.html
Logic being a normative science must depend on math and phenomenology.
Of course, it all depends on what a person means by "logic" ...
JA: I also observe that Peirce takes the individual objects of
a particular universe of discourse in a "generative" way,
not a "totalizing" way, and thus they afford us with the
basis for talking freely about collections, constructions,
properties, qualities, subsets, and "higher types", as
the phrase is mint.
JR: Would this be essentially the same as regarding quantification as
distributive rather than collective, i.e. we take the individuals
of a class one-by-one as selectable rather than as somehow given
all at once, collectively?
Gosh, that's a harder question. Your suggestion reminds me
of the way that some intuitionist and even some finitist
mathematicians talk when they reflect on math practice.
I have leanings that way, but when I have tried to
give up the classical logic axioms, I have found
them too built in to my way of thinking to quit.
Still, a healthy circumspection about about our
often-wrongly vaunted capacties to conceive of
totalities is a habitual part of current math.
Again, I think individuals are made not born,
that is, to some degree factitious and mere
compromises of this or that conveniency.
This is one of the reasons that I have
been trying to work out the details
of a functional approach to logic,
propostional, quantificational,
and relational.

Discussion Note 31
Many illusions of selective reading -- like the myth that Peirce did not discover quantification over indices until 1885 -- can be dispelled by looking into his 1870 "Logic of Relatives". I started a web study of this in 2002, reworked again in 2003 and 2004, the current version of which can be found here: LOR. http://stderr.org/pipermail/inquiry/2004-November/thread.html#1750 LOR-COM. http://stderr.org/pipermail/inquiry/2004-November/thread.html#1755 LOR-DIS. http://stderr.org/pipermail/inquiry/2004-November/thread.html#1768 I've only gotten as far as the bare infrastructure of Peirce's 1870 LOR, but an interesting feature of the study is that, if one draws the pictures that seem almost demanded by his way of linking up indices over expressions, then one can see a prototype of his much later logical graphs developing in the text.
Discussion Work Areas
Discussion Work Area 1
BM: Several discussions could take place there,
as to the reasons for the number of divisions,
the reasons of the titles themselves. Another
one is my translation from "normal interpretant"
into "final interpretant" (which one is called
elsewhere "Eventual Interpretant" or "Destinate
Interpretant" by CSP). I let all this aside
to focus on the following remark:
BM: 6 divisions correspond to individual correlates:
(S, O_i, O_d, I_i, I_d, I_n),
3 divisions correspond to dyads:
(S : O_d, S : I_d, S : I_n),
and the tenth to a triad:
(S : O_d : I_n).
This remark would itself deserve
a lot of explanations but one
more time I let this aside.
BM: Then we have the following very clear statement from Peirce:
| It follows from the Definition of a Sign
| that since the Dynamoid Object determines
| the Immediate Object,
| which determines the Sign,
| which determines the Destinate Interpretant
| which determines the Effective Interpretant
| which determines the Explicit Interpretant
|
| the six trichotomies, instead of determining 729 classes of signs,
| as they would if they were independent, only yield 28 classes; and
| if, as I strongly opine (not to say almost prove) there are four other
| trichotomies of signs of the same order of importance, instead of making
| 59049 classes, these will only come to 66.
|
| CSP, "Letter to Lady Welby", 14 Dec 1908, LW, p. 84.
BM: The separation made by CSP between 6 divisions and four others
seems to rely upon the suggested difference between individual
correlates and relations. We get the idea that the 10 divisions
are ordered on the whole and will end into 66 classes (by means of
three ordered modal values on each division: maybe, canbe, wouldbe).
Finally we have too the ordering for the divisions relative to the
correlates that I write in my notation:
Od -> Oi -> S -> If -> Id -> Ii.
BM: This order of "determinations" has bothered many people
but if we think of it as operative in semiosis, it seems
to be correct (at least to my eyes). Thus the question is:
where, how, and why the "four other trichotomies" fit in this
schema to obtain a linear ordering on the whole 10 divisions?
May be the question can be rephrased as: how intensional
relationships fit into an extensional one? Possibly the
question could be asked the other way. R. Marty responds
that in a certain sense the four trichotomies give nothing
more than the previous six ones but I strongly doubt of this.
BM: I put the problem in graphical form in an attached file
because my message editor will probably make some mistakes.
I make a distinction between arrow types drawing because I am
not sure that the sequence of correlates determinations is of
the same nature than correlates determination inside relations.
BM: It looks as if the problem amounts to some kind of projection
of relations on the horizontal axis made of correlates.
BM: If we consider some kind of equivalence (and this seems necessary to
obtain a linear ordering), by means of Agent -> Patient reductions on
relations, then erasing transitive determinations leads to:
Od -> Oi -> S -> S-Od -> If -> S-If -> S-Od-If -> Id -> S-Id -> Ii
BM: While it is interesting to compare the subsequence
S-Od -> If -> S-If -> S-Od-If with the pragmatic maxim,
I have no clear idea of the (in-) validity of such a result.
But I am convinced that the clarity has to come from the
Logic Of Relatives.
BM: I will be very grateful if you can make something with all that stuff.
Discussion Work Area 2
BM: I also found this passage which may be of some interest
(CP 4.540, Prolegomena to an Apology of Pragmatism):
| But though an Interpretant is not necessarily a Conclusion, yet a
| Conclusion is necessarily an Interpretant. So that if an Interpretant is
| not subject to the rules of Conclusions there is nothing monstrous in my
| thinking it is subject to some generalization of such rules. For any
| evolution of thought, whether it leads to a Conclusion or not, there is a
| certain normal course, which is to be determined by considerations not in
| the least psychological, and which I wish to expound in my next
| article;†1 and while I entirely agree, in opposition to distinguished
| logicians, that normality can be no criterion for what I call
| rationalistic reasoning, such as alone is admissible in science, yet it
| is precisely the criterion of instinctive or common-sense reasoning,
| which, within its own field, is much more trustworthy than rationalistic
| reasoning. In my opinion, it is self-control which makes any other than
| the normal course of thought possible, just as nothing else makes any
| other than the normal course of action possible; and just as it is
| precisely that that gives room for an ought-to-be of conduct, I mean
| Morality, so it equally gives room for an ought-to-be of thought, which
| is Right Reason; and where there is no self-control, nothing but the
| normal is possible. If your reflections have led you to a different
| conclusion from mine, I can still hope that when you come to read my next
| article, in which I shall endeavor to show what the forms of thought are,
| in general and in some detail, you may yet find that I have not missed
| the truth.
JA: Just as I have always feared, this classification mania
appears to be communicable! But now I must definitely
review the Welby correspondence, as all this stuff was
a blur to my sensibilities the last 10 times I read it.
BM: I think that I understand your reticence. I wonder if:
a. the fact that the letters to Lady Welby have been published as such,
has not lead to approach the matter in a certain way.
b. other sources, eventually unpublished, would give another lighting on
the subject, namely a logical one. I think of MS 339 for example that
seems to be part of the Logic Notebook. I have had access to some pages
of it, but not to the whole MS.
BM: A last remark. I don't think that classification is a mania for CSP but I
know that you know that! It is an instrument of thought and I think that
it is in this case much more a plan for experimenting than the exposition
of a conclusion. Experimenting what ? There is a strange statement in a
letter to W. James where CSP says that what is in question in his "second
way of dividing signs" is the logical theory of numbers. I give this from
memory. I have not the quote at hand now but I will search for it if needed.

BM = Bernard Morand

JA: ... but now I have to add to my do-list the problems of comparing
the whole variorum of letters and drafts of letters to Lady Welby.
I only have the CP 8 and Wiener versions here, so I will depend
on you for ample excerpts from the Lieb volume.
BM: I made such a kind of comparison some time ago. I selected the following
3 cases on the criterium of alternate "grounds". Hoping it could save
some labor. The first rank expressions come from the MS 339 written in
Oct. 1904 and I label them with an (a). I think that it is interesting to
note that they were written four years before the letters to Welby and
just one or two years after the Syllabus which is the usual reference for
the classification in 3 trichotomies and 10 classes. The second (b) is
our initial table (from a draft to Lady Welby, Dec. 1908, CP 8.344) and
the third (c) comes from a letter sent in Dec. 1908 (CP 8.345-8.376). A
tabular presentation would be better but I can't do it. Comparing (c)
against (a) and (b) is informative, I think.

Discussion Work Area 4
JA: It may appear that one has side-stepped the issue of empiricism
that way, but then all that stuff about the synthetic a priori
raises its head, and we have Peirce's insight that mathematics
is observational and even experimental, and so I must trail off
into uncoordinated elliptical thoughts ...
HC: In contrast with this it strikes me that not all meanings of "analytic"
and "synthetic" have much, if anything, to do with the "analytic and the
synthetic", say, as in Quine's criticism of the "dualism" of empiricism.
Surely no one thinks that a plausible analysis must be analytic or that
synthetic materials tell us much about epistemology. So, it is not
clear that anything connected with analyticity or a priori knowledge
will plausibly or immediately arise from a discussion of analytical
geometry. Prevalent mathematical assumptions or postulates, yes --
but who says these are a prior? Can't non-Euclidean geometry also
be treated in the style of analytic geometry?
HC: I can imagine the a discussion might be forced in
that direction, but the connections don't strike me
as at all obvious or pressing. Perhaps Jon would just
like to bring up the notion of the synthetic apriori?
But why?
Discussion Work Area 5
HC = Howard Callaway
HC: But I see you as closer to my theme or challenge, when you say
"The question is about the minimal adequate resource base for
defining, deriving, or generating all of the concepts that we
need for a given but very general type of application that we
conventinally but equivocally refer to as 'logic'".
HC: I think it is accepted on all sides of the discussion that there
is some sort of "equivalence" between the standard predicate logic
and Peirce's graphs.
There you would be mistaken, except perhaps for the fact that
"some sort of equivalence" is vague to the depths of vacuity.
It most particularly does not mean "all sorts of equivalence"
or even "all important sorts of equivalence". It is usually
interpreted to mean an extremely abstract type of syntactic
equivalence, and that is undoubtedly one important type of
equivalence that it is worth examining whether two formal
systems have or not. But it precisely here that we find
another symptom of syntacticism, namely, the deprecation
of all other important qualities of formal systems, most
pointedly their "analystic, "semantic", and "pragmatic"
qualities, which make all the difference in how well the
system actually serves its users in a real world practice.
You can almost hear the whining and poohing coming from the
syntactic day camp, but those are the hard facts of the case.
HC: But we find this difference in relation to the vocabulary used to express
identity. From the point of view of starting with the predicate calculus,
we don't need "teridentity". So, this seems to suggest there is something
of interesting contrast in Peirce's logic, which brings in this concept.
The obvious question may be expressed by asking why we need teridentity
in Peirce's system and how Peirce's system may recommend itself in contrast
to the standard way with related concepts. This does seem to call for
a comparative evaluation of distinctive systems. That is not an easy task,
as I think we all understand. But I do think that if it is a goal to have
Peirce's system better appreciated, then that kind of question must be
addressed. If "=" is sufficient in the standard predicate calculus,
to say whatever we may need to say about the identity of terms, then
what is the advantage of an alternative system which insists on always
expressing identity of triples?
HC: The questions may look quite different, depending on where we start.
But in any case, I thought I saw some better appreciation of the
questions in your comments above.
Discussion Work Area 6
It's been that way for about as long as anybody can remember, and it will remain so, in spite of the spate of history rewriting and image re-engineering that has become the new rage in self-styled "analytic" circles.
Discussion Work Area 7
The brands of objection that you continue to make, with no evidence
of reflection on the many explanations that I and others have taken
the time to write out for you, lead me to believe that you are just
not interested in making that effort. That's okay, life is short,
the arts are long and many, there is always something else to do.
HC: For, if I make an assertion A&B, then I am not asserting
that the statement A stands in a relation to a statement B.
Instead, I am asserting the conjunction A&B (which logically
implies both the conjuncts in view of the definition of "&").
If "&" counts as a triadic relation, simply because it serves
to conjoin two statements into a third, then it would seem that
any binary relation 'R' will count as triadic, simply because
it places two things into a relation, which is a "third" thing.
By the same kind of reasoning a triadic relation, as ordinarily
understood would be really 4-adic.
HC: Now, I think this is the kind of argument you are making, ...
No, it's the kind of argument that you are making.
I am not making that kind of argument, and Peirce
did not make that kind of argument. Peirce used
his terms subject to definitions that would have
been understandable, and remain understandable,
to those of his readers who understand these
elementary definitions, either though their
prior acquaintance with standard concepts
or through their basic capacity to read
a well-formed, if novel definition.
Peirce made certain observations about the structure of logical concepts
and the structure of their referents. Those observations are accurate
and important. He expressed those observations in a form that is clear
to anybody who knows the meanings of the technical terms that he used,
and he is not responsible for the interpretations of those who don't.
HC: ... and it seems to both trivialize the claimed argument
for teridentity, by trivializing the conception of what
is to count as a triadic, as contrasted with a binary
relation, and it also seems to introduce a confusion
about what is is count as a binary, vs. a triadic
relation.
Yes, the argument that you are making trivializes
just about everything in sight, but that is the
common and well-known property of any argument
that fails to base itself on a grasp of the
first elements of the subject matter.
HC: If this is mathematical realism, then so much the worse for
mathematical realism. I am content to think that we do not
have a free hand in making up mathematical truth.
No, it's not mathematical realism. It is your reasoning,
and it exhibits all of the symptoms of syntacticism that
I have already diagnosed. It's a whole other culture
from what is pandemic in the practice of mathematics,
and it never fails to surprise me that people who
would never call themselves "relativists" in any
other matter of culture suddenly turn into just
