What you’ve said about Jon’s MEGs, though, is true only if we read the lines in those diagrams as Lines of Identity; and the main modification Jon made was to read the lines NOT as Lines of Identity but as Lines of Relation.
I agree. But it violates the principles of EGs, since it doesn't put an explicit marker at the intersection. With the label Rel at the intersection, the MEGs become EGs. Since Peirce never said that the result was a new kind of EG, that would be what he had intended.
It’s not clear to me how sequences of MEGs could be used to analyze the thought process into the smallest possible steps
Please drop the word MEG. Every operation that Peirce specified converted one EG to another EG that expressed exactly the same proposition with a different choice of relations. That puts the Aristotelian transformation into perspective: it's replaces one relation with a copula. Peirce learned that method at age 13, and he developed the idea over the years. The word 'thought' is misleading for modern ears, since it sounds too psychological. Peirce said that thoughts exist outside the mind. But most readers don't think in those terms. It's better to use the neutral word 'proposition'.
The analysis of propositions is only one aspect of EGs as “moving pictures of thought,” and the rules for permissible transformations of graphs are the keys for analyzing the process of thought.
I strongly agree. In fact, that's the motivation for a talk i presented at a Peirce session of the Vancouver APA in April 2015: "Peirce, Polya, and Euclid: Integrating logic, heuristics, and geometry" http://jfsowa.com/talks/ppe.pdf
I share with Gary R a deep interest in phenomenology/phaneroscopy — and especially the observational part (as opposed to the analytical part) of it.
That's my motivation for the ppe.pdf slides. See the concluding slide of ppe.pdf, which is attached as ppe.png. There's much more to say, but I believe that EGs that contain arbitrary icons (in any number of dimensions) can simulate the phaneron. John
