<QUOTE Paul Ricoeur>

If exegesis raised a hermeneutic problem, that is, a problem

of interpretation, it is because every reading of a text always

takes place within a community, a tradition, or a living current

of thought, all of which display presuppositions and exigencies —

regardless of how closely a reading may be tied to the *quid*, to

“that in view of which” the text was written.

All,

If a picture is worth a thousand words, here’s my 48,000 words

worth on the periodically recurring question of logical graphs,

their iconicity, and their interpretation, at least so far as

Peirce’s alpha graphs interpreted for propositional logic go.

A few more actual words, literally speaking, may be called for.

I’ll return to that anon.

Referring to the Table —

• Column 1 shows a conventional name fₙ and a venn diagram

for each of the sixteen boolean functions on two variables.

• Column 2 shows the logical graph canonically representing the

boolean function in Column 1 under the entitative interpretation.

This is the interpretation C.S. Peirce used in his earlier work

on entitative graphs and the one Spencer Brown used in his book

Laws of Form.

• Column 3 shows the logical graph canonically representing the

boolean function in Column 1 under the existential interpretation.

This is the interpretation C.S. Peirce used in his later work on

existential graphs.

<QUOTE C.S. Peirce>

In the first place there are likenesses or copies — such as statues,

pictures, emblems, hieroglyphics, and the like. Such representations

stand for their objects only so far as they have an actual resemblance

to them — that is agree with them in some characters. The peculiarity

of such representations is that they do not determine their objects —

they stand for anything more or less; for they stand for whatever

they resemble and they resemble everything more or less.

The second kind of representations are such as are set up by

a convention of men or a decree of God. Such are tallies,

proper names, &c. The peculiarity of these conventional

signs is that they represent no character of their objects.

Likenesses denote nothing in particular; conventional signs

connote nothing in particular.

The third and last kind of representations are symbols or general

representations. They connote attributes and so connote them as

to determine what they denote. To this class belong all words

and all conceptions. Most combinations of words are also symbols.

A proposition, an argument, even a whole book may be, and should be,

a single symbol.

All,

The Table in the previous post can now be sorted to bring out the

“family resemblances”, likenesses, or symmetries among logical graphs

and the boolean functions they denote, where the “orbits” or similarity

classes are determined by the dual interpretation of logical graphs.

Performing the sort produces the following Table. As we have

seen in previous discussions, there are 10 orbits in all,

4 orbits of 1 point each and 6 orbits of 2 points each.

I’m impressed that you have read Ricoeur — my impression is

that Americans don’t have much time for Continental philosophy

(a huge generalisation of course).

Have you looked at Habermas? He uses Peirce's work as well as

hermeneutics (mainly Gadamer) and critical theory to come up

with what he calls a theory of communicative action. He also

called it “universal pragmatics” at one time as a nod to both

Chomsky and semiotics.

</QUOTE>

Dear John,

That observation from Ricoeur’s Conflict of Interpretations comes

from a time when Susan Awbrey and I were exploring the synergies

of action research, critical thinking, classical and post-modern

hermeneutics, and Peirce’s triadic relational semiotics.

We benefited greatly from our study of Gadamer, Habermas, Ricoeur

and a little more from Derrida, Foucault, Lyotard, aided by the

lucid surveys of Richard J. Bernstein. All that culminated in a paper

we presented at a conference on Hermeneutics and the Human Sciences,

subsequently published as “Interpretation as Action : The Risk of Inquiry”.

( https://www.academia.edu/1266493/Interpretation_as_Action_The_Risk_of_Inquiry ).

I found Ricoeur’s comment fitting in the present connection because it

speaks to the way identical modulations of a medium may convey different

messages to different cultures and contexts of communication. Conversely,

conveying the same message to different cultures and contexts of communication

may require different modulations of the same medium.

That is precisely situation we observe in the Table from Episode 1,

for ease of reference repeated below. The objects to be conveyed

are the 16 boolean functions on 2 variables, whose venn diagrams

appear in Column 1. And we have the two cultures of interpreters,

Entitative and Existential, whose graphical and parenthetical forms

of expression for the boolean functions are shown in Column 2 and

Column 3, respectively.

Dear John,

I hesitate to call any sketch Peirce gave of the big three sign types

a “standard Peircean trichotomy of icon, index, symbol”. Several

considerations give me pause on this point.

• Peirce gave so many instructive and useful characterizations

of the main sign types over the years I'd be hard-pressed to

declare any one text definitive. It is not that we have a

hermeneutic circle where every text is granted equal weight,

only that it takes more analysis to define the terms as yet

undefined and to sort all terms involved in order of their

mutual and sole dependencies.

• A cursory inspection of Peirce's sign types, from major to minor,

shows we rarely if ever have true k-tomies, in the sense of exhaustive

and mutually exclusive categories. True, we often speak of dichotomies

and trichotomies in loose terms, but now and again loose speech has led

to sinking ontologies.

Oops, more to say but need to break for midday sustenance …

Jon
