Sign Relations, Triadic Relations, Relation Theory • 1

To understand how signs work in Peirce’s theory of triadic sign relations, or “semiotics”, we have to understand, in order of increasing generality, sign relations, triadic relations, and relations in general, each as conceived in Peirce’s logic of relative terms … Continue reading

Theme One • A Program Of Inquiry 19

Re: Richard J. Lipton • Knowledge Is Good It’s the usual thing to say scientific inquiry involves a combination of deductive and inductive reasoning.  A slightly different, 3-phase model, going back to Aristotle and revived by Charles S. Peirce, analyzes … Continue reading

Animated Logical Graphs • 44

Re: FB | Ecology Of Systems Thinking • Richard Saunders RS:  DNA and proteins might be good places to look for logical graphs in nature since our tech for mapping those structures has become fairly proficient lately.  Do you think … Continue reading

Animated Logical Graphs • 43

Re: FB | Ecology Of Systems Thinking • Richard Saunders RS:  I wonder if we might find such graphs in the physical microstructures of brains, cells, proteins, etc. Dear Richard, You are reading my mind.  See the following post on … Continue reading

Pragmatic Semiotic Information • Discussion 20

Re: R.J. Lipton and K.W. Regan • IBM Conference on the Informational Lens A little bit of history recoded … It may be worth noting the Information Revolution in our understanding of science began in the mid 1860s when C.S. Peirce … Continue reading
