## Differential Logic, Dynamic Systems, Tangent Functors • Discussion 1

Re: Cybernetics • Stuart Umpleby Susan and I just returned from our annual dramatic immersion in Stratford Ontario and the last play we saw was a playfully dramatic rendition of Milton’s Paradise Lost.  That and the spectacular immorality play currently … Continue reading

## Differential Logic, Dynamic Systems, Tangent Functors • 1

People interested in category theory as applied to systems may wish to check out the following article, reporting work I carried out while engaged in a systems engineering program at Oakland University. The problem addressed is a longstanding one, that … Continue reading

## Differential Logic • Comment 3

In my previous comment on boundaries in object universes and venn diagrams, and always when I’m being careful about their mathematical senses, the definitions of “topology” and “boundary” I have in mind can be found in any standard textbook.  Here are … Continue reading

## Differential Logic • Comment 2

As always, we have to distinguish between the diagram itself, the representation or sign inscribed in some medium, and the formal object it represents under a given interpretation. A venn diagram is an iconic sign we use to represent a … Continue reading

Re: Gil Kalai • Pivotal Variables Just a tangential association with respect to logical influence and pivotability.  I have been exploring questions related to pivotal variables (“Differences that Make a Difference” or “Difference In ⟹ Difference Out”) via logical analogues … Continue reading

## Differential Logic

The Logic of Change and Difference Differential logic is the logic of variation — the logic of change and difference. Differential logic is the component of logic whose object is the description of variation, for example, the aspects of change, … Continue reading
