Peirce’s 1870 “Logic of Relatives” • Comment 3

Posted on February 3, 2022 by Jon Awbrey

In passing to more complex combinations of relative terms and the extensional relations they denote, as we began to do in Comments 10.6 and 10.7, I used words like composite and composition along with the usual composition sign to describe … Continue reading →

Re: Conceptual Graphs • Gary Zhu GZ: I’m quite confused on why people are interested in Laws of Form. What is LOF trying to do? Is it just rewriting logic or is there something more fundamental. e.g. a universal algebraic … Continue reading →

Peirce’s 1870 “Logic of Relatives” • Discussion 5

Posted on January 8, 2022 by Jon Awbrey

Re: Conceptual Graphs • Peiyuan Zhu PZ: I’m studying imprecise probabilities which initially works as an extension in Boole’s Laws of Thoughts.  It seems like Boole was solving a set of algebraic equations for probabilities where some of the probabilities … Continue reading →

Re: Peirce’s 1870 “Logic of Relatives” • Proto-Graphical Syntax Re: FB | Ancient Logic • Henning Engebretsen HE: What’s your point, it’s obviously too graphical, but perhaps you are driving at something else.  Explain? Dear Henning, My aim here is … Continue reading →

Posted on December 10, 2021 by Jon Awbrey

All other sciences without exception depend upon the principles of mathematics;  and mathematics borrows nothing from them but hints. C.S. Peirce • “Logic of Number” A principal intention of this essay is to separate what are known as algebras of … Continue reading →

Survey of Relation Theory • 5

Posted on November 8, 2021 by Jon Awbrey

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 →
