Survey of Differential Logic • 3

This is a Survey of blog and wiki posts on Differential Logic, material I plan to develop toward a more compact and systematic account. Note.  One effect of the pandemic has been been to blot out my memory of much … Continue reading

Differential Logic • Comment 5

Re: Peirce List • John Sowa : “Modal Logic Is An Immense Swamp” Dear John, Best title I’ve read in a long time!  But the really immense swamp critter here is the Naturally Evolved Organon known as ornery natural language which … Continue reading

Definition and Determination • 20

Re: Peirce List • Robert Marty RM: Thank you for this information.  I happen to have a work in progress (not yet written) on the question of determination.  I discovered that Peirce gave a quite remarkable definition in CP 8.361. “We … Continue reading

Definition and Determination • 19

Re: Peirce List • Edwina Taborsky JA: I needed to start thinking of semiotics and sign relations in the light of cybernetics and systems theory.  That required me to convert from understanding a sign relation as a relation among three … Continue reading

Definition and Determination • 18

Various discussions in sundry places led me by a commodius vicus of recirculation back to the environs of old notes I gathered on the topics of Definition and Determination, that being on the occasion of a return to graduate school … Continue reading

Survey of Animated Logical Graphs • 4

This is a Survey of blog and wiki posts on Logical Graphs, encompassing several families of graph-theoretic structures originally developed by Charles S. Peirce as graphical formal languages or visual styles of syntax amenable to interpretation for logical applications. Beginnings Logical Graphs … Continue reading
