Survey of Relation Theory • 5

In this Survey of blog and wiki posts on Relation Theory, relations are viewed from the perspective of combinatorics, in other words, as a topic in discrete mathematics, with special attention to finite structures and concrete set-theoretic constructions, many of … Continue reading

Relation Theory • Discussion 3

Re: Relation Theory • (1) • (2) • (3) • (4) • (5) Re: Laws of Form • James Bowery JB: Thanks for that very rigorous definition of “relation theory”. Its “trick” of including the name of the -relation in … Continue reading

Relation Theory • Discussion 2

Re: Relation Theory • (1) • (2) • (3) • (4) Re: FB | Charles S. Peirce Society • Joseph Harry JH: These are iconic representations dealing with logical symbolic relations, and so of course are semiotic in Peirce’s sense, … Continue reading

Notes On Categories • 2

Re: Category Theory • Joe Moeller JM: In category theory, we have this perspective that we should focus attention on maps, on the relationships between objects, rather than on the objects themselves.  What’s your favorite examples of people giving a … Continue reading

Re: Category Theory • Henry Story Re: Laws of Form • Lyle Anderson LA: As I am trying to get “frame sync” on this discussion, as the satellite communications people say, I am taking clues from the introduction to the … Continue reading

Re: Category Theory • Henry Story HS: I’d be very interested in the comments of people who know about Peirce on the two chapters in the book Diagrammatic Immanence I linked to above on “3. Peirce” and “4. Diagrams of Variation : … Continue reading

C.S. Peirce and Category Theory • 6

Re: Category Theory • Henry Story HS: I’d love it of course if all of Peirce’s graphs could be mapped to CT.  That would help me integrate that work a lot faster.  Or alternatively, if one could work out exactly … Continue reading

Re: C.S. Peirce and Category Theory • 2 Re: Category Theory • Henry Story • Avi Craimer • Henry Story Dear Avi, Henry, Diagrams are a mixed bag, a complex and polymorphic species, in Peircean semiotics.  All diagrams in common use, … Continue reading

Re: Category Theory • Kyle Rivelli KR: I really enjoyed the Diagrammatic Immanence book. Gangle has another book that goes into more depth with Peirce: Gianluca Caterina and Rocco Gangle (2016), Iconicity and Abduction. Thanks, Kyle, I’ve been looking at … Continue reading
