Hi Jon, List,

Happy Pi Day!

Before addressing your question, Jon, I would ask you to spend a couple of minutes thinking about where you would place your own studies and analysis of existential graphs (EGs) within Peirce's Classification (use the 1903 'perennial' one). . . .

OK. So, the first thing I would say is that the study of knowledge representation (KR), in my view, subsumes the study of EGs. So the first answer is to place KR as the parent of where you placed EG. An EG is a specialized notation and rules for expressing logical relationships in a symbolic language, which is (should be) one character of any formal KR system.

Second, as for my own placement, my book [1, Part II] places the study of KR under speculative grammar, as I explain in Chapter 7. The book itself is called a '/practionary/' (in Kelly Parker's coinage [2, p 182], which he kindly allowed me to borrow), which is "all the practical effects a thing could have in experience, and thus furnish the reader with a better conception of the object.” Parker coined this term to capture Peirce's discomfort (1902, NEM 4.30) with his "imperfect" earlier expression of the pragmatic maxim “Consider what effects, which might conceivably have practical bearings, we conceive the object of our conceptions to have. Then, our conception of these effects is the whole of our conception of the object” (1878, CP 5.402). Parker saw the usefulness of laying out all of the practical effects a thing may have (a 'practionary'), but that a “third-grade of clearness of apprehension" also required personal "hands-on" experience. A practionary is thus an approach under methodeutic. It is not surprising that the study of KR is closely aligned to formal semiotic (or what Peirce also called 'categorics').

I can see a bit of your logic in suggesting KR to be placed under the 'Science of Review' but I think that applicable more to the assembly or collection of extant KR systems or KR artifacts (if at all) than to the study of them as a science. (Thus, KBpedia as a KR instantiation could be placed there.) Beverly Kent [3, p 81] notes Peirce disdained this approach as the "exudation" or "fossilized remains" of science as a "systematized or organized body of knowledge". My understanding of Peirce's classification of the sciences, obviously much informed by Kent, is that principles and methods are the heart of the matter, not a static organization or systematization. Still, as Peirce developed and Kent then documents, he undertook at least 20 different classifications over the period of 1866 to 1903 with many more minor ones. There are many perspectives to be brought to bear on the questions of classification.

Lastly, I appreciate your contextual expressions of the categories under Peirce's classification, but I do not view your expressions as uniformly applicable across the branches as do you. In formal semiotic itself, there are at least three universal category interpretations each under speculative grammar, critic, and methodeutic [1, Table 6-2]. There is something universal about the categories, but that resides in their 'final cause' as well as specific instantiations in different contexts.

BTW, I have been slowly releasing the chapters [4] of my book in free preprint versions, to be completed in the next month or so. Much more on all of these topics is discussed there. I will complete that release over the next few weeks, but I am happy to enable list members to obtain them now either for the full book [1] or by individual chapters [4]. If the specific chapter link is not yet active, simply substitute the relevant number in the URL to get it now.

Best, Mike

Mike, List:

A quick follow-up note--it seems obvious in retrospect, but it occurred to me today that knowledge representation presumably falls under what Peirce in his classification of the sciences calls "Science of Review," which comes between "Science of Discovery" (mathematics, philosophy, special sciences) and "Practical Science."

    CSP: By "science of review" is meant the business of those who
    occupy themselves with arranging the results of discovery,
    beginning with digests, and going on to endeavor to form a
    philosophy of science. Such is the nature of Humboldt's /Cosmos/,
    of Comte's /Philosophie positive/, and of Spencer's /Synthetic
    Philosophy/. The classification of the sciences belongs to this
    department. (CP 1.182, EP 2:258-259, 1903)

    CSP: Let science of review include all handbooks and digests, all
    such works as those [of] Comte, Whewell, and Spencer, all
    classifications and all histories of science, etc. (EP 2:458, 1911)


Do you agree? If so, then it only makes sense that the most salient manifestations of 1ns/2ns/3ns would be different in that discipline (monads/particulars/generals) than in phenomenology, where they are found in their purest form (quality/reaction/mediation)--just as they are different in normative science (feeling/action/thought), logic as semeiotic (possibles/existents/necessitants), and metaphysics (characters/things/habits).

Thanks again,

Jon

        MB: I'm in agreement with most of your points, but differ in two.


    I am not sure that we really disagree even on those two.

        MB: First, I chose monads, particulars and generals for KKO in
        context to knowledge representation and the correspondence
        with instances/classes in current KR languages.


    This seems like mostly a difference in emphasis. As I have
    admitted to you before, I do not know much about the discipline of
    knowledge representation, so I will take your word for it that the
    terminology of monads/particulars/generals is more appropriate for
    your purposes within that context than quality/reaction/mediation.

        MB: We know about the general modern discussion of information
        and energy, and quite a few researchers have related this to
        Peirce, entropy, and the 2nd law of thermodynamics
        (Hermann-Pillith, Annila, Salthe, me).


    I am not familiar with any of that literature either, so I will
    refrain from further comment until you are able "to put forward a
    coherent narrative."

        Hi Jon, List:

        I'm in agreement with most of your points, but differ in two.
        First, I chose monads, particulars and generals for KKO in
        context to knowledge representation and the correspondence
        with instances/classes in current KR languages. I'm not sure I
        have a firm sense that Peirce himself had a firm sense of
        which characterization he preferred. Your preferred canonical
        version is 'quality, reaction, and mediation', not a bad
        choice that I agree he propones, but he strongly proposed a
        few variants and again that raises the contextual issue. I
        simply can not see how one can fully understand the universal
        categories without understanding their commonalities and
        essences across instances of use. This is basic hierarchy and
        categorization 101.

        Second, Peirce is explicit about the depth and breadth of
        information (1867, CP 2.407-8) or what he also called the area
        (CP 2.419), a view he maintained for more than 35 years (1903,
        EP 2:305), as you picked up in his later defense. This was a
        major contributor to the discussion of intension and extension
        in my hierarchy paper. We know about the general modern
        discussion of information and energy, and quite a few
        researchers have related this to Peirce, entropy, and the 2nd
        law of thermodynamics (Hermann-Pillith, Annila, Salthe, me).
        The relation to energy therefore deserves close inspection,
        and our basic E = mcc does employ an area, only now one of
        light. Since speed of light (c) is also a time concept, this
        is perhaps evidence that time prescinds space. There is a
        major theme underlying this that I will discuss with the list
        when I am ready to put forward a coherent narrative.

        Thanks, Mike
