Relations & Their Relatives • Discussion 14

Re: Peirce List Discussion • GF • JBD • HR I think a few people are making this harder than it needs to be. Let’s put aside potential subtleties about elementary vs. individual vs. infinitesimal relatives and simply use “elementary … Continue reading

Relations & Their Relatives • Discussion 13

Re: Peirce List Discussions • (1) • (2) First off, we need to be clear about the difference between objects and signs: Relations are formal objects of discussion and thought while relative terms are signs employed to denote relations.  (The … Continue reading

Survey of Relation Theory • 2

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

Peirce’s Categories • 3

Re: Peirce List Recent travels and other travails (dental work) have scattered my thoughts to the four winds, so let me just document a few bits from my current state of mind in case I can get back to it … Continue reading

Peirce’s Categories • 2

Re: Peirce List • Jeffrey Brian Downard • Gary Richmond • John Collier According to Peirce, it is logic that draws on both mathematics and phenomenology. At any rate, Peirce takes the distinctive position that normative science, which includes logic, … Continue reading

Peirce’s Categories • 1

Re: Peirce List • Jeffrey Brian Downard Just from my experience, the best first approach to questions of firstness, secondness, thirdness, and so on is to regard k-ness as the property that all k-adic relations possess in common.  There is … Continue reading

What Makes An Object? • 2

Re: Peirce List Discussison • (1) • (2) Visual metaphors and perceptual analogies can be instructive — they make for most of my personal favorites — but in logic, mathematics, and science our interest extends through the abductive spectrum, from … Continue reading

What Makes An Object? • 1

Re: Gary Fuhrman • Seeing Things What makes an object is a perennial question. I can remember my physics professors bringing it up in a really big way when I was still just a freshman in college.  They always cautioned … Continue reading

Zeroth Law Of Semiotics • Comment 7

Re: Peirce List I still have in mind trying to show how the principle I dubbed the Zeroth Law Of Semiotics can help us see what is really going on with a number of old puzzles like the Liar Paradox, … Continue reading

Zeroth Law Of Semiotics • Comment 6

Re: Peirce List By way of orientation to the task at hand, we are investigating a type of slippage that occurs in the gap between natural language, with the natural assumptions it has evolved to take for granted, rightly or … Continue reading
