Tenacity, Authority, Plausibility, Inquiry

Re: Peter Cameron • Mathematics and Logic My favorite polymathematician, Charles Sanders Peirce, gave a fourfold classification of what he called “methods of fixing belief”, or “settling opinion”, most notably and seminally in his paper, “The Fixation of Belief” (1877).  … Continue reading

Theme One • A Program Of Inquiry 3

Re: Peirce List • Gary Richmond The program I wrote for my M.A. in Psych was barely a prototype, a “test of concept”, as they say, but I continued to develop and apply the underlying collection of ideas to a number … Continue reading

Theme One • A Program Of Inquiry 2

Re: Peirce List • Jerry Chandler I think I was probably the first person in that particular psychology department to submit a program as a master’s thesis, at any rate they didn’t have regular procedures set up for that kind … Continue reading

Theme One • A Program Of Inquiry 1

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

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

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

Triadic Relations, Intentions, Fuzzy Subsets • Discussion 2

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

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

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
