Now that I have proved sufficiently that everything comes to pass according to determinate reasons, there cannot be any more difficulty over these principles of God’s foreknowledge. Although these determinations do not compel, they cannot but be certain, and they … Continue reading

## Sign Relational Manifolds : 5

Peircers, Let me try to say in intuitive terms what I think is really going on here. The problem we face is as old as the problem of other minds, or intersubjectivity, or even commensurability, and it naturally involves a … Continue reading

## Sign Relational Manifolds : 4

Peircers, I found another set of notes on this theme that appear to get to the point more quickly, and though they read a little rough in places I think it might be worth the effort to fill out their … Continue reading

## Sign Relational Manifolds : 3

Peircers, I made several attempts to articulate the connections between manifold theory and semiotics in the context of numerous list discussions that interwove each other through diverse nooks of the web in the early years of the present millennium. Here … Continue reading

## Sign Relational Manifolds : 2

Peircers, Here is a set of excerpts from Doolin and Martin (1990), Introduction to Differential Geometry for Engineers, that I used in discussing differentiable manifolds with other participants in the IEEE Standard Upper Ontology Working Group. What brought the concept … Continue reading

## Sign Relational Manifolds : 1

Peircers, Riemann’s concept of a manifold, especially as later developed, bears a close relationship to Peirce’s concept of a sign relation. I’ll have to wait for my present train of thought to stop at a station before I can hop … Continue reading
