Triadic Relations, Intentions, Fuzzy Subsets • Discussion 1

Posted on December 6, 2012 by Jon Awbrey

Re: Peirce List Discussion • Stefan Berwing Frequencies, histograms, and probabilities are one way to think about degrees of membership in a fuzzy subset, but there are cautions to be observed in doing that. Consider the following triadic relations: x … Continue reading →

Triadic Relations, Intentions, Fuzzy Subsets • 1

Posted on November 27, 2012 by Jon Awbrey

Re: Foundations Of Math Discussion • Lotfi Zadeh Way back during my first foundational crisis (1967–1972), I had been willing to consider almost any alternatives to the usual set theories, so I can remember looking at early accounts of fuzzy … Continue reading →

Peircean Semiotics and Triadic Sign Relations • 2

Posted on June 27, 2012 by Jon Awbrey

When I returned to graduate school for the third time around, this time in systems engineering, I had in mind integrating my long‑standing projects investigating the dynamics of information, inquiry, learning, and reasoning, viewing each as a process whose trajectory evolves … Continue reading →

Peircean Semiotics and Triadic Sign Relations • 1

Posted on June 27, 2012 by Jon Awbrey

As a “guide for the perplexed”, at least when it comes to semiotics, I’ll use this thread to collect a budget of resources I think have served to clarify the topic in the past. By way of a first offering, … Continue reading →

C.S. Peirce • Of Triadic Being

Posted on June 14, 2012 by Jon Awbrey

Selection from C.S. Peirce, “Some Amazing Mazes, Fourth Curiosity” (c. 1909) Of triadic Being the multitude of forms is so terrific that I have usually shrunk from the task of enumerating them; and for the present purpose such an enumeration would … Continue reading →

Paradisaical Logic and the After Math

Posted on April 9, 2012 by Jon Awbrey

Re: Peter Cameron • Cultures, Tribes, or Just an Illusion? Re: Peirce List • (1) (2) (3) (4) Not too coincidentally with the mention of Peirce’s existential graphs, a tangent of discussion elsewhere brought to mind an old favorite passage … Continue reading →

C.S. Peirce • Relatives of Second Intention

Posted on April 7, 2012 by Jon Awbrey

Selections from C.S. Peirce, “The Logic of Relatives”, CP 3.456–552 488.   The general method of graphical representation of propositions has now been given in all its essential elements, except, of course, that we have not, as yet, studied any truths … Continue reading →

Hypostatic Abstraction

Posted on August 8, 2008 by Jon Awbrey

Hypostatic Abstraction (HA) is a formal operation on a subject–predicate form that preserves its information while introducing a new subject and upping the “arity” of its predicate. To cite a notorious example, HA turns “Opium is drowsifying” into “Opium has dormitive virtue”. Continue reading →

Logic of Relatives

Posted on July 31, 2008 by Jon Awbrey

The logic of relatives, more precisely, the logic of relative terms, is the study of relations as represented in symbolic forms known as “rhemes”, “rhemata”, or “relative terms”. Continue reading →

Semeiotic

Posted on July 30, 2008 by Jon Awbrey

Theory of Signs Semeiotic is one of the terms C.S. Peirce used for his theory of triadic sign relations and it serves to distinguish his theory of signs from other approaches to the same subject matter, more generally referred to … Continue reading →
