Pragmatic Semiotic Information • Discussion 21

Re: FB | Medieval LogicKollbjorn OldtheynEdward Buckner

On the question of which later developments in logic Peirce anticipated, I’ve been more focused on the points where he saw through to features we would not see again until the theories of categories, computation, and information began to make their impact on our conceptions of logic.  I’ll dig up some links along those lines …

WB:

Weird how we’ve been doing this for so many years!  I look forward to what you have to say.  Dunno if you’ve seen this, may be of interest.

We built some stuff similar to logic graphs, we called distinction networks (d-nets), in the deep past.  Here’s some implementation details (1995) for asynchronous d-net computation.  Ran it first on an Intel Hypercube with 16 nodes (ugh, course-grain parallelism — a technical abstract (1987) at “The Losp Parallel Deduction Engine” (PDF)) and eventually migrated to a distributed network architecture in which each node was an independent operating system, more for the convenience of doing VR than for the elegance of fine-grain logic parallelism.

Distinction Networks

Abstract.  Intelligent systems can be modeled by organizationally closed networks of interacting agents.  An interesting step in the evolution from agents to systems of agents is to approach logic itself as a system of autonomous elementary processes called distinctions.  Distinction networks are directed acyclic graphs in which links represent logical implication and nodes are autonomous agents which act in response to changes in their local environment of connectivity.  Asynchronous communication of local decisions produces global computational results without global coordination.  Biological/environmental programming uses environmental semantics, spatial syntax, and boundary transformation to produce strongly parallel logical deduction.

Dear William,

Thanks for the readings.  Maybe I’ve just got McCulloch on the brain right now but the things I’m reading in several groups lately keep flashing me back to themes from his work.  What you wrote on distinction networks took me back to the beginnings of my interest in AI, especially as approached from logical directions.  There’s a couple of posts on my blog where I made an effort to point up what I regard as critical issues.  I’ll reshare those next and see if I can throw more light on what’s at stake.

Re: Ontolog ForumMichael DeBellis

MDB:
I’ve just started taking Peirce seriously in the last year or so and some of his more complex ideas still aren’t completely clear to me but here goes:  Has anyone come up with an OWL upper model (i.e., something like the upper models in Cyc and BFO) based on Peirce’s work?  I’ve come to appreciate Peirce as a major figure in the history of logic, information theory, semiotics, etc. but I’ve never quite been able to map his ideas into a logical model in OWL.  I’m not sure if this is because trying to do so isn’t consistent with what Peirce is trying to do or just that I still haven’t grasped his ideas completely.  Or perhaps the subset of FOL that OWL supports isn’t powerful enough to map to Peirce.  At an initial reading it seems like there should be a good fit because (at least as I understand it) one of Peirce’s core ideas of symbols (as opposed to icons or indexes) seems like a perfect fit to the triple model (Subject Predicate Object) that is the foundation (RDF/RDFS) for OWL.  Would like to know your opinions on this.

Dear Michael,

Google still reminds me I spent some time on the RDF-Logic List back around the turn of the millennium (January 2001).  I was especially intrigued by the prospect of using triples as a fundamental data structure.  Now the (subject, verb, object) triples of RDF and the (object, sign, interpretant) triples of Peirce’s semiotics are ostensibly different data types in their concrete descriptions but that may not obstruct integration too much if the triples are defined abstractly enough and implemented polymorphically enough.  As far as I can remember, though, the concrete connotations tended to get in the way of cross-cultural or trans-silo communication at that time.

That is not, however, the largest obstacle to harmonizing the logic of Peirce with the ways of FOL as she is spoke today.  I’ll take that up when I next get a chance …

Regards,

Jon

Re: Laws of FormDirk Baecker

DB:
Watzlawick’s request for a pragmatic calculus of communication up to now was never appropriately answered.  W. Barnett Pearce and Vernon E. Cronen (Communication, Action, and Meaning : The Creation of Social Realities, 1980) did important studies on this as did Anthony Wilden (System and Structure : Essays in Communication and Exchange, 1972), but we still lack it.

Dear Dirk,

Watzlawick’s request for a pragmatic calculus of communication recalls McCulloch’s earlier question whether the human capacity for insightful learning and reasoning demands a grasp of trans-dyadic relations, or not.

But the problem of insight, or intuition, or invention — call it what you will — we do not understand, although many of us are having a go at it.  […]  Tarski thinks that what we lack is a fertile calculus of relations of more than two relata.  I am inclined to agree with him, and if I were now the age I was in 1917, that is the problem I would tackle.

That process of insight by which a child learns at least one logical particle, neither or not both, when it is given only ostensively — and one must be so learned — is still a little beyond us.  It may perhaps have to wait for a potent logic of triadic relations, but I now doubt it.  (McCulloch, p. 15).

The way I see things today, my motto would be Context Precedes Calculus if I had to sum it up as briefly as possible.  In other words, the first order of business is finding the right context for understanding the phenomena and problems at hand.  As far as the human capacity for conversing with nature and our fellows goes, pragmatic thinkers informed by Peirce would no doubt point to the context of triadic sign relations and declare, “Eureka!  This Must Be The Place.”

Re: Laws of FormWilliam Bricken

WB:
Kauffman’s 2001 piece on “Peirce” (title is “The Mathematics of Charles Sanders Peirce” [PDF]) is IMO fundamental to this discussion.
Here’s a brief excerpt from a piece I did in 2005:
“Boundary Logic and Alpha Existential Graphs (AEG)”

4.3  LoF and Alpha Graphs Compared

AEG applies the diagrammatic structure of enclosure specifically to logic. The representations of LoF and AEG are isomorphic, while the systems of transformation rules are remarkably close to being the same.  …

Dear William,

Many thanks for your excerpt.  It highlights many of the most critical points in comparing the systems of Peirce and Spencer Brown so I’ll take up the topic of duality first.  Over the years I’ve always found that to be one of the stickier wickets in the whole field.  I’ll discuss it in my Animated Logical Graphs series as that’s where I’ve recently redoubled my efforts to explain the issue and why it’s important.

Regards,

Jon

Re: Gil KalaiChomskian Linguistics

Oneirocritical Interlude

Speaking of dreams, the night before last I had a dream where I was listening to a lecturer and something he said brought to mind a logical formula having the form ``\text{if if if } a, b, c, d", which I visualized as the Peircean logical graph shown below.

If If If

I knew I had seen something the day before prompting that fragment and a search through my browser history turned up Gil Kalai’s post on Chomskian Linguistics where I’d read the phrase “anti anti anti missile missile missile missile”.

Re: Laws of FormDirk Baecker

DB:
I guess you know Fernando Zalamea’s work on Peirce.  He thinks that all of GSB’s important ideas are already in Peirce’s Existential Graphs.
I think he may be right, but then there is the issue of elegance, beauty, and clarity, and here, GSB leads the field.

Dear Dirk,

As you may have gleaned from the bio-graphical narrative I’ve been salvaging from the old LoF group, I started down the intertwining Logical Graph / Laws of Form road sometime in the late 60s, all of which took me pretty far along my own eigenvectors before I hit on the work of Zalamea and others of that persuasion in the present millennium.

In most of the things I’ve written in the past about the relative contributions of Peirce and those who came after, Spencer Brown in particular, I tended to give Peirce a lot of credit for anticipating the developments others clarified or brought to fruition.  More lately I’ve observed just how bewildered the untutored reader can become when faced with Peirce’s writings on logical graphs and logic generally, so I’ve been rethinking my apportionment of credit.  At any rate, I commented on what I thought was added by whom all through my bio essay and I will continue doing that as I go.

Regards,

Jon

Re: Laws of FormDirk Baecker

DB:
Thanks to James Bowery for inviting me to this group.  Maybe it is not exactly what I am looking for, since I am interested in a sociological reading of LoF.  Which means that I am searching for a mathematics more akin to semantics than to physics.  I am still not sure whether in this respect LoF is a wonderful metaphor to understand basic features of an oscillating communication or whether chapter 11 opens up possibilities to compute semantic values starting with imaginary states.

Dear Dirk,

Thanks for this comment and all the links.  I’ve been working along the lines of Peirce’s logical graphs and Spencer Brown’s calculus of indications in parallel since those heady early days of the late 60s and Peirce’s semiotics or theory of triadic sign relations is very much a piece of how I understand both.  In that light I’ll feel encouraged to share bits of that along with my work on LoF — and now everyone knows who to blame!  😉

Regards,

Jon

Much of the work I do on the C.S. Peirce/Spencer Brown approach to “mathematical hypostases underlying logic” now goes under the heading of Animated Logical Graphs.  There’s a Survey of related resources I update from time to time at the following location.

Charles Sanders Peirce, George Spencer Brown, and Me • 11

There’s a new Laws of Form group in town.  James Bowery et al. have just revived the earlier group on a new platform and everything looks pretty handy so far.  There’s an honest-to-goodness 60s vibe about it for me since it’s well-known to those in the know how Spencer Brown’s work builds on Peirce’s, not just because his calculus of indications resurrects aspects of Peirce’s alpha level logical graphs but because the broader scope of his interests touched on inductive reasoning and the whole welter of knotty tangles in the pragmatics of communication, computation, concept formation which Arbib, Ashby, Bateson, Korzybski, R.D. Laing, McCulloch, Peirce, Polanyi, Watzlawick, and others probed in the matrix of quasi-paradoxes and games people play with symbols.

All of which inspires me to revise and extend the series of posts I shared with the old group a few years back, fixing in passing the large number of now broken links.
