Inquiry Driven Systems • Comment 2

I just got reminded of an earlier blog post that more or less fits here.  It links to the bibliography I had in hand and mind when I went back to graduate school in systems engineering to synthesize all the … Continue reading

Re: Facebook Discussion • Meredith Bricken Mills I’ve always been fond of picture proofs — it was one of the things that drew me to graph theory, topology, and the logical graphs of C.S. Peirce and Spencer Brown in the first place.  … Continue reading

Re: Richard Coyne • Inside Out Logic Venn diagrams make for very iconic representations of their universes of discourse.  That is one of the main sources of their intuitive utility and also the main source of their logical limitations — … 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

Peirce’s 1903 Lowell Lectures • Comment 10

Re: Peirce List Discussion • John Sowa JFS: In the Lowell Lectures [1903] Peirce defined the Sheet of Assertion as the representation of a universe that was constructed during a discourse between Graphist and Grapheus. But that is just one … Continue reading

Peirce’s 1903 Lowell Lectures • Comment 9

Re: Peirce List • John Sowa JFS: In 1911, Peirce clarified [the] issues by using two distinct terms:  ‘the universe’ and ‘a sheet of paper’.  The sheet is no longer identified with the universe, and there is no reason why one couldn’t or … Continue reading
