Survey of Relation Theory
• https://inquiryintoinquiry.com/2023/07/26/survey-of-relation-theory-7/

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 which arise quite naturally in applications. This approach to relation theory is distinct from, though closely related to, its study from the perspectives of abstract algebra on the one hand and formal logic on the other.

Here's the beginning of a prospective blog series I started … this topic interacts strongly with a host of others I've been struggling to articulate over the years …

❝Computations or Processes —
How do you think about the building blocks of the brain?❞

I keep coming back to this thread about levels, along with others on the related issue of paradigms, as those have long been major questions for me. I am trying to clarify my current understanding for a blog post. It will start out a bit like this —

A certain amount of “level” language is natural in the sciences but “level” metaphors come with hidden assumptions about higher and lower places in hierarchies which don't always fit the case at hand. In complex cases what look at first like parallel strata may in time be better comprehended as intersecting domains or mutually recursive and entangled orders of being. When that happens we can guard against misleading imagery by speaking of domains or realms instead of levels.

To be continued …

@AndriusKulikauskas

Just for starters, the signified thing is called the object. It's one component of an ordered triple \((o, s, i)\) called an #ElementarySignRelation, consisting of an object, sign, and interpretant sign, in a set of triples called a #SignRelation.

@mikefriedline @mattslocombe @cognition @cogsci @psychology

Q. What exactly is developing?

A. From a highly formal and #Semiotic point of view, what develops is a #SignRelation.

P.S. The basic idea is really as old as #Aristotle, with a few new twists by C.S. #Peirce, who taught #WilliamJames psychology could be an experimental science.
