List: In my reading of CSP, Jon’s response lacks substance.
I find the rest of your paragraph to lack any relevance to my concerns in relating CSP writing to the modal logic used in proof theory as he described in his papers on the role of copula in predicaments. Perhaps you are ignoring the differences between combinatorial sentences deploying the copula as a plural connector and “predicate" logics? At issue in many of CSP’s curious prescriptions are the forms of propositions such as that raised by Russell in his paper “On Denotation.” The mystery of the meaning of a "line of identity” deepens with every passing year. Perhaps my concern would be more transparent if the difference that makes a difference were expressed in the termini, Indefinite Description and Definite Description. The triad, Semiotics, Semiology and Semantics necessarily requires the later.
