John, List: I did not say anything (yet) about continuous *predicates*; I referred to Peirce's direct analogy between continuous *motion* and *semeiosis *vs. discrete *positions/instants* and definite *Propositions*. It seems safe to assume that what he had in mind for "stereoscopic moving pictures" would have taken full advantage of this conceptual correspondence.
I agree with what you quoted and stated below about the Line of Identity, and it also applies to the Blank as the Graph of Coexistence; these always have room for additional attachments, and thus are really representations of *teridentity *and *tercoexistence*. There are other continuous predicates that only qualify as such because they cannot be further analyzed into a subject and a *different *predicate--possessing a character or belonging to a class/collection, represented by the single Peg of a monadic Spot; and standing in a relation, represented by the multiple Pegs of a dyadic or higher Spot. FYI, I recently came across some research suggesting that the manuscript pages for Peirce's "tutorial" on EGs were *misfiled *with R 514, and do not actually date to 1909; rather, he likely wrote the material either shortly before or at the same time as his June 22, 1911 letter to Mr. Kehler. This makes a lot of sense, given his abrupt shift from presenting Cuts as thin oval lines in R 669 (May 25 - June 2) to instead advocating shading in R 670 (June 7-17).
