Sign Relations • Dyadic Aspects

For an arbitrary triadic relation whether it is a sign relation or not, there are six dyadic relations obtained by projecting on one of the planes of the -space   The six dyadic projections of a triadic relation are defined … Continue reading

Animated Logical Graphs • 33

A reader’s request for more examples of animated logical graphs prompted me to look again at the User Guide for my Theme One Program, whose exposition develops a series of logical graphs increasing in complexity from extremely simple to more substantial … Continue reading

Differential Logic • Discussion 3

Re: R.J. Lipton • P<NP Instead of boolean circuit complexity I would look at logical graph complexity, where those logical graphs are constructed from minimal negation operators. Physics once had a frame problem (complexity of dynamic updating) long before AI … Continue reading

Sign Relations • Examples

Because the examples to follow have been artificially constructed to be as simple as possible, their detailed elaboration can run the risk of trivializing the whole theory of sign relations.  Despite their simplicity, however, these examples have subtleties of their … Continue reading

Sign Relations • Discussion 4

Re: Peirce List • Edwina Taborsky A note on a couple of recurring themes may be useful at this point. Peirce’s “metaphorical argument” for transforming discussion of interpretive agents, whether individuals or communities, to discussion of interpretant signs is as … Continue reading

Re: R.J. Lipton and K.W. Regan • Proof Checking Dear Dick/Ken, Here’s a place where I explore different shapes of proofs in a propositional calculus deriving from the graphical systems of Charles S. Peirce and G. Spencer Brown. Propositional Equation Reasoning Systems • Analysis … Continue reading

Sign Relations • Discussion 3

Re: Sign Relations • Definition Re: Ontolog Forum • Alex Shkotin (1) (2) Regarding Peirce’s definition of a sign linked above, Alex Shkotin writes: A Sign is unusually active in Peirce’s definition: A (a sign) brings B (interpretant sign) into … Continue reading

Sign Relations • Signs and Inquiry

There is a close relationship between the pragmatic theory of signs and the pragmatic theory of inquiry.  In fact, the correspondence between the two studies exhibits so many congruences and parallels it is often best to treat them as integral … Continue reading

Re: Cybernetics • Bernard C.E. Scott Re: Sign Relations • Definition Regarding Peirce’s definition of a sign given in the previous post, Bernard Scott writes: It is very helpful [to] distinguish Peirce’s formal semiotic (his logic) from psychological, and by … Continue reading
