Re: Peirce List • Jerry Chandler • Jon Awbrey • Gary Richmond • Christophe Menant I view psychology, throughout its many branches, as a fascinating and compelling collection of subjects, so much so I spent one of my parallel lives … Continue reading →

Constants, Inconstants, and Higher Order Propositions

Posted on December 20, 2012 by Jon Awbrey

A question arising on the Foundations Of Math List gives me an opportunity to introduce the subject of higher order propositions, which I think afford a better way to handle the situations of confusion, doubt, obscurity, uncertainty, and vagueness often … Continue reading →

Demonstrative And Otherwise

Posted on December 17, 2012 by Jon Awbrey

I am constantly encountering what I perceive as echoes of Peircean themes in places where acquaintance with or interest in Peirce’s work is slight at best, and that leaves me with a lot of pent up thoughts that I’ve learned through … Continue reading →

Re: Peirce List Discussion • Gary Moore • Stefan Berwing I intend to get back to this subject as soon as possible but the dire political situation in my home state is once again eating up a lot of my … Continue reading →

Triadic Relations, Intentions, Fuzzy Subsets • Discussion 2

Posted on December 8, 2012 by Jon Awbrey

Re: Peirce List Discussion • Stefan Berwing Let us put fuzzy sets to one side for the moment and take up the matter of belief you raised, as I believe that connection is very apt. As it happens, there was … Continue reading →

Triadic Relations, Intentions, Fuzzy Subsets : 3

Posted on December 7, 2012 by Jon Awbrey

There is at present an extensive literature on fuzzy sets and fuzzy logic.  I got another brush with the world of fuzzy in the 1990s when I returned to grad school in a systems engineering program, partly because my adviser … Continue reading →

Triadic Relations, Intentions, Fuzzy Subsets : 2

Posted on December 7, 2012 by Jon Awbrey

We imagine all the things we might want to talk about in a given discussion as collected together in a set X called a universe of discourse.  (In probabilistic or statistical work it might be called a sample space.) By … Continue reading →

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 →

“Is it possible to advance philosophy today?”

Posted on November 25, 2012 by Jon Awbrey

Re: Stephen Rose Is it possible to advance philosophy today?  To do so, one would have to use terms that appear to have evolved in different disciplines to a point where dialog is almost impossible, even when desired. I suppose … Continue reading →
