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

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

Peirce’s 1870 “Logic of Relatives” • Discussion 4

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

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

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

Triadic Relations • Discussion 3

Re: Triadic Relations • (1) • (2) • (3) Re: Conceptual Graphs • Edwina Taborsky ET: A few comments on your outline of the Sign.  I think one has to be careful not to set up a Saussurian linguistic dyad.  … Continue reading

Survey of Semiotics, Semiosis, Sign Relations • 2

This is a Survey of blog and wiki resources on the theory of signs, variously known as semeiotic or semiotics, and the actions referred to as semiosis which transform signs among themselves in relation to their objects, all as based … Continue reading

Functional Logic • Inquiry and Analogy • Preliminaries

This report discusses C.S. Peirce’s treatment of analogy, placing it in relation to his overall theory of inquiry.  We begin by introducing three basic types of reasoning Peirce adopted from classical logic.  In Peirce’s analysis both inquiry and analogy are complex … Continue reading

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

Triadic Relations • 2

Triadic Relations • Examples from Mathematics For the sake of topics to be taken up later, it is useful to examine a pair of triadic relations in tandem.  We will construct two triadic relations, and each of which is a … Continue reading
