Animated Logical Graphs : 12

Re: Facebook Discussion • MBM 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.  Sue was … 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

Re: Laws Of Form Discussion With any formal system it is easy to spend a long time roughing out primitives and reviewing first principles before getting on to practical applications, and logical graphs are no different in that respect.  But … Continue reading

Re: Laws Of Form Discussion • Boundary Logic • RS A wider field of investigation opens up at this point, having to do with the diversity of interactions among the languages we use, and systems of signs in general, to … Continue reading

Re: Laws Of Form Discussion • Boundary Logic • JW For me, the heart of the matter is what is the purpose of logic and what is the purpose of math and what is their relationship? There are semiotic situations … Continue reading

Re: Laws Of Form Discussion • Boundary Logic • CB A statement that implies both and is called a false statement, and anyone can prove anything at all from a false statement, as we all too frequently observe on the … Continue reading

Re: Laws Of Form Discussion • Peirce’s Law • AM • AM The formal system of logical graphs is defined by a foursome of formal equations, called initials when regarded purely formally, in abstraction from potential interpretations, called axioms when … Continue reading
