Metaphor and model was central to my Ph.D. dissertation - which is when I first encountered MacCormac (<span style="font-family:"Courier New"" class="font">MacCormac,Earl R., A Cognitive Theory of <span style="font-size:11pt" class="size">Metaphor, Cambridge,Mass.: MIT Press, 1985)</span></span>. I have had many pleasant conversations with Nick on this topic at Friam.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">2) Many of the comments I made originally will be resolved by understanding each other's interpretations of words and phrases.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">3) I have a deeply viscerally negative reaction tot he concept and word of Truth/truth and that antipathy is at the foundation of my "objections" to the explanation-description-explanation stack.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Clearly, some kind of starting point is required; from which a theory can be developed. What seems, to me, to be necessary is an explanation-model-metaphor sufficiently "stable" that the energies of investigation can be focused on intended and unintended consequences with little effect on the "foundation." (I keep having mental visions of waves eating away at the cliffs and houses sliding into the ocean versus waves crashing against rocks and leaving the structures above intact.)<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">I think that a means for establishing some kind of "stable" starting point is your actual objective, not some kind of "truthy" foundation.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">The metaphor of a 'stable foundation' inspires the idea that stability is relative and proportional to both the structure to be erected on that foundation, and the context in which the foundation must be established. Long ago when I was an expediter for a housing company, we built the foundation for a two-story home in 3-5 days (most of which was concrete drying and curing). To build a 100 story office tower requires a more elaborate and stable foundation that might take a few months to establish. Just up the street from my office, they are building a small three story building and have been working on the foundation (cofferdams, pilings, piers, etc.) for nine-months now.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">I am increasingly curious about the theory you intend to erect on the metaphor/model you will establish.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">4) My ignorance of the details of evolution and Darwin has created the perception that evolutionary explanations are focused on discrete species. The broken-wing behavior of the killdeer evolves/is-selected-for in a kind of "isolation," as a response to pressures on the killdeer alone.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Hence my question about the gullibility of the fox and notions of co-evolution.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Is it possible to develop a theory of evolution at the complex-system (e.g. killdeer, fox, and slected aspects of their shared ecological niche) level? A complex system begins at some kind of equilibrium, is disturbed by change in any of its elements, and seeks a new equilibrium.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Comparison of the relative duration of a given equilibrium state and/or the degree to which it could accommodate discrete disruptions and still "recover" its initial equilibrium (or close approximation in the sense of a strange attractor) and other measures might be used to establish "fitness."<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Bottom line, I will enjoy participating in any discussion — hopefully for mutual benefit — but even on a selfish personal learning basis.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">davew<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;"><br></div><div>On Mon, Jan 13, 2020, at 6:11 AM, thompnickson2@gmail.com wrote:<br></div><blockquote id="qt-qt" type="cite"><div class="qt-qt-WordSection1"><p class="qt-qt-MsoNormal">Dear Eric and David,<br></p><p class="qt-qt-MsoNormal"> <br></p><p class="qt-qt-MsoNormal">David’s reading of that work is by far the most perceptive and profound critique I have ever received of our metaphors and models theory, and I a profoundly grateful for it.

The pencil fell, because the cat swatted it.” If you could say, “I think you’re initial premise is wrong, the pencil didn’t fall”, then you would be challenging the description. The same phrase is explanatory in “Why is the pencil on the floor? The pencil is on the floor, because the pencil fell.” If could say, “I don’t think that’s how it got that way, nothing fell, Jill picked the pencil up and put it on the ground” then you would be challenging the explanation. </span></span><span style="font-family:"Arial", sans-serif" class="font"><br><br></span> [David] <span style="font-family:"Arial", sans-serif" class="font">Their goal is to be "scientific" and so "truthy" models must remain and become fundamental to the evaluation of explanations.

A description simply says what happened, whereas an explanation says why it happened."<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Followed by an argument that description and explanation are pretty close to the same thing: all descriptions explain; all explanations describe, and both are in some sense, interpretations.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Then a discussion that leads right back to the same distinction: "Descriptions are explanations that the speaker and audience take to be true for the purpose of seeking further explanations. Conversely, explanations are descriptions that the speaker and audience hold to be unverified under the present circumstances." <br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">There is, however, a (in my mind) subtle error here, in that the assertion just quoted uses the word "true" as if it was the same thing as "assumed for the purposes of argument" — the conclusion of the argument about differences — which it is not. Similarly, "unverified" is not the same as "contested absent further information;."<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">I presume that this error? was intentional, as they need descriptions and, later, models to have this "truthiness" quality.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">The discussion of explanations as models with 'basic" and "surplus" implications (surplus being divided into "intended" and "unintended") parallels and, except for vocabulary, duplicates McCormac's discussion of the evolution of metaphor from epiphor to either "lexical term" or "dead metaphor." [Unlike Glen, I have no difficulty with metaphor as a kind of philosopher's stone for sense-making in science.] <br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">The discussion of levels of explanations is where the need for "truthy" descriptions comes back into play. Somewhere in our hierarchy of models is the need for a "true" purely descriptive model. Even within any given model there is a need to accept the "Basic Meaning" as being "true" and purely descriptive, so we can go about researching and verifying (or not) the intended "surplus meanings."<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Although it is evident how and why they need "truth" in order to proceed with their discussion and argument, I am unwilling to grant it. For me, both explanations and descriptions are "interpretations" with no qualitative differentiation.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Their goal is to be "scientific" and so "truthy" models must remain and become fundamental to the evaluation of explanations. Evaluation is taken to be a two step process, with each step having three aspects.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Specify the explanation:<br></div><div style="font-family:Arial;"> 1. find the foundational (root of the theory) "true" description.<br></div><div style="font-family:Arial;"> 2. expose the model - i.e. the metaphor.<br></div><div style="font-family:Arial;"> 3. expose the intended surplus implications such that research can begin to verify/disprove them.<br></div><div style="font-family:Arial;">Evaluate the explanation<br></div><div style="font-family:Arial;"> 1. discard the explanation if there are no surplus implications exposed for investigation.<br></div><div style="font-family:Arial;"> 2. confirm the basic implications<br></div><div style="font-family:Arial;"> 3. prove some number of the intended surplus implications to be "true."<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Nice and tidy - except it does not / cannot work this way. Just like the "scientific method" in general, this construct can serve, at best, as an after the fact rationalization of a course of investigation.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Absent a "true" description at its root, a theory becomes a Jenga tower of speculation.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">"Confirmation" of basic implications is too often a "political" exercise — so too any "proving" of surplus implications as "true" — witness the Copenhagen Interpretation of Quantum Physics. (Or, in the case of 'proving" things, the fact that string theory and many other quantum theories generate no testable intentional surplus implications.)<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">It is far too easy to move inconvenient (i.e. unprovable) "intended surplus implications to the "unintended' category — witness Artificial Intelligence and the mind-is-computer-is-mind model/metaphor.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">The "unintended" surplus implications might, more often than not, be more important than the "intended" ones — witness epigenetics.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Reliance on models, even structured models like those proposed, eliminates "context" because all models are, if not abstractions, simplifications; focusing only on what is deemed 'relevant."<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">This last point makes me want to read the rest of Eric's and Nick's book, because I suspect I would find agreement with the last point of my argument.
