Riffs and Rotes • Happy New Year 2021

Apart from their abstract beauty, Riffs and Rotes are structures I discovered while playing around with Gödel numberings of graphs and digraphs.  To my way of thinking they bear a deep connection to the mathematical infrastructure of logic.  Here are … Continue reading

Sign Relations, Triadic Relations, Relation Theory • Discussion 3

Re: Peirce List • Helmut Raulien HR: As Peircean semiotics is a three-valued logic, I think it bears relevance for the discussion about multiple-valued logic. Dear Helmut, The distinction between “k-adic” (involving a span of k dimensions) and “k-tomic” (involving … Continue reading

Survey of Inquiry Driven Systems • 3

This is a Survey of blog and wiki posts on Inquiry Driven Systems, material I plan to refine toward a more compact and systematic treatment of the subject. An inquiry driven system is a system having among its state variables … Continue reading

Survey of Abduction, Deduction, Induction, Analogy, Inquiry • 2

This is a Survey of blog and wiki posts on three elementary forms of inference, as recognized by a logical tradition extending from Aristotle through Charles S. Peirce.  Particular attention is paid to the way these inferential rudiments combine to … Continue reading
