Re: Peirce List Discussions • (1) • (2)
Discussion arose in the Laws Of Form Group about computational explorations of George Spencer Brown’s calculus of indications.
Readers of Peirce are generally aware that Spencer Brown revived certain aspects of Peirce’s logical graphs, focusing on the Alpha level interpretable for Boolean Algebra and Propositional Calculus but adding some hints of potential extension and generalization. He used what amounts to Peirce’s entitative interpretation of the graphical forms in his exposition but was clear about the abstract character of the forms themselves, as evidenced by their admitting dual interpretations, dubbed “entitative” and “existential” by Peirce.
In computational context the question naturally arises how to code the abstract formal structures used by the calculi of CSP and GSB into the relatively concrete forms that a computer can process.
I began my response to that question as follows …
