## Theme One Program • Exposition 4

Parsing Logical Graphs It is possible to write a program that parses cactus expressions into reasonable facsimiles of cactus graphs as pointer structures in computer memory, making edges correspond to addresses and nodes correspond to records.  I did just that … Continue reading

## Theme One Program • Exposition 3

Coding Logical Graphs My earliest experiments coding logical graphs as dynamic “pointer” data structures taught me that conceptual and computational efficiencies of a critical sort could be achieved by generalizing their abstract graphs from trees to the variety graph theorists … Continue reading

## Theme One Program • Exposition 2

The previous post described the elementary data structure used to represent nodes of graphs in the Theme One program.  This post describes the specific family of graphs employed by the program. Painted And Rooted Cacti Figure 1 shows a typical example … Continue reading

## Theme One Program • Exposition 1

Theme One is a program for constructing and transforming a particular species of graph‑theoretic data structures, forms designed to support a variety of fundamental learning and reasoning tasks. The program evolved over the course of an exploration into the integration of … Continue reading

## Survey of Theme One Program • 4

This is a Survey of blog and wiki posts relating to the Theme One Program I worked on all through the 1980s.  The aim was to develop fundamental algorithms and data structures for integrating empirical learning with logical reasoning.  I … Continue reading

## Theme One Program • Discussion 6

Re: Peirce List • Jerry Chandler JC: This post [Theme One Program • Motivation 1] is so muddled that I gave up on a meaningful scientific interpretation of it. Dear Jerry, Thanks for the response. I heartily agree with the … Continue reading

## Theme One Program • Discussion 5

I’ve been going back and looking again at the problems and questions which nudged me into the computational sphere as a way of building our human capacities for inquiry, learning, and reasoning. One critical issue, you might even say bifurcation … Continue reading

## Relatives Of Second Intention • Comment 5

Re: C.S. Peirce • Relatives of Second Intention Re: Peirce List (1) (2) • John Sowa (1) (2) Re: Peirce List • Jon Alan Schmidt JAS: Thanks for providing a longer excerpt of that passage than I did, including Peirce’s … Continue reading

## Relatives Of Second Intention • Comment 4

Re: C.S. Peirce • Relatives of Second Intention Re: Laws of Form • Lyle Anderson LA: Here Peirce is confusing Truth and Falsity with Good and Evil.  The Creator of the Universe (CotU) created Truth and Falsity when He drew the … Continue reading

## Relatives Of Second Intention • Comment 3

Re: C.S. Peirce • Relatives of Second Intention Re: FB | Medieval Logic • Kollbjorn Oldtheyn Dear Kollbjorn, I used to think I knew what Peirce was talking about in this passage but it looks like it may be time … Continue reading
