Re: [PEIRCE-L] Meta-languages. Re: Four branches of existential graphs: Alpha, Beta, Gamma, Delta
Jerry, As you know very well, there is a huge difference in the various kinds of chemical bonds.In a combination of a noun phrase (NP) and a verb phrase (VP). The NP is analogous to a sodium ion Na with a negative charge, and the VP is analogous to a sulfate ion (SO4) with a positive charge. The resulting combination NaSO4 is a compound with a neutral charge that corresponds to a sentence that states a proposition. The negative NP ion corresponds to a rheme, which combines with a positive VP ion to form a neutral proposition. But in organic chemistry, bonds between carbon atoms share electrons. Those chemical bonds don't have the same kinds of analogies with linguistic bonds or with the links in EGs. JLRC: Which of the logical particles would associated with a metalanguage in the example cited by Roberts? Peirce's first recorded example of metalanguage in RLT had a complete sentence "you are a good girl" (which would correspond to a neutral chemical compound) as the subject of a verb phrase, which would have a positive charge. In effect, the word 'that' when attached to a neutral sentence gives it a negative charge so that it could be used as the subject of a positively charged verb phrase "--is much to be wished." As far as I know, Peirce did not use a chemical analogy to explain that combination. Can you suggest some example in chemistry that would correspond to the word 'that'? It would have to take a neutral compound that would correspond to a sentence such as "You are a good girl" and attach some atoms that could form a link to a positive radical, such as "--is much to be wished." For example, the organic acid pattern -COOH would link a neutral organic radical to negative -OH radical or to a negative Na ion. Is there some organic pattern that could link a neutral molecule to a positive ion? That could correspond to the word 'that'.

The following is an excerpt from Robert’s book, page 22: What is a reasonable interpretation about the “blanks” in sentences relative to concatenations of logical operations between the posits and the consequences? How would the blanks be relative to the copula? Copula’s of “metalanguages? What would be the number of metalanguages necessary for a conclusion from a posited pragmatic sentence with n blanks? Which of the logical particles would associated with a metalanguage in the example cited by Roberts? Have fun!

[PEIRCE-L] The philosophy of logic of John Corcoran - LUW March 27, 4pm CET
Logica Universalis Webinar March 27, 2024 at 4pm CET Speaker: José M. Sagüillo Department of Philosophy, University of Santiago de Compostela, Spain Title: "The philosophy of logic of John Corcoran" Abstract: "This talk surveys the philosophy of logic of John Corcoran by focusing on some of its characteristic themes: his understanding of logic as formal epistemology articulating the ontic-epistemic distinction of classical metaphysics, the Socratic belief-knowledge distinction, and the Aristotelian truth-knowledge distinction; his conception of mathematical logic as instrumental when considering mathematical logics as models of underlying reasoning found in the practice of proof; his tireless search for a careful and successful communication in a community of thinkers eliminating ambiguity of key terms and embracing ethical values; his discussion of argumentations and logic as a philosophical realization of the previous dichotomies, allowing precise definitions of key concepts, such as, argument, argumentation, proof, deduction, fallacy, and paradox; finally, his recovering and articulation of the XIX century information-theoretic conception of validity, exploring its heuristic power in the study of omega arguments and suggesting the existence of different paradigms of logical consequence equally entrenched in the theory and practice of logic." https://link.springer.com/book/9783031444609 Universal Logic, Ethics, and Truth Essays in Honor of John Corcoran (1937-2021) https://link.springer.com/book/9783031444609 Presented by the editors of the book: Timothy Madigan and Jean-Yves Beziau Chair : Francesco Paoli, Editorial Board SUL Everybody is welcome to join, register here: https://link.springer.com/journal/11787/updates JYB Founder, Editor, Organizer LU / SUL / LUW https://philpeople.org/profiles/jean-yves-beziau _ _ _ _ _ _ _ _ _ _ ARISBE: THE PEIRCE GATEWAY is now at https://cspeirce.com and, just as well, at https://www.cspeirce.com .
