I collect sobriquets for Grice. In ONE source, he is referred to as "British logician"; the OED used to have him as "linguist". He was of course a _plain_ philosopher, simpliciter, if that's the word. Platts called Grice, "a philosopher's philosopher", which is confusing (it confuses me). In the body of the article, the 'philosopher-logician' of the title becomes a plain 'philosopher': >Ruth Barcan Marcus, a philosopher esteemed for her >advances in logic, a traditionally male-dominated subset of a traditionally male-dominated field, died on >Feb. 19. Note the sarcasm: 'subset' -- that's a male-dominated choice of a noun, then? Note the sarcasm: a male-dominated field may have a non-male-dominated subset, and so on. >she retired in 1992 as the Reuben Post Halleck professor of philosophy. Yale can confuse. Oxford has it easy: all professorship chairs start with W Wykeham -- prof of logic. Waynflete -- prof of metaphysics White -------- prof of ethics Wilde -------- prof of mental philosophy. ---- >For a woman of Professor Marcus’s generation to elbow her way into the field, ... was almost unheard of. It would be interesting to trace about the earliest female logician ever. I think the first Greek female philosopher ever was good at logic, too? >“The rest of philosophy became less male dominated, less macho, more quickly than logic,” Stephen Neale, said in a telephone interview. “She was working in a field which was really run by these giants.” --- I wonder if that's what he said, in the telephone interview. Perhaps he meant, "less male dominated, less 'macho'...": i.e. perhaps he used scare quotes for 'macho', but then what can a telephone interview know? "Quantified logic centers on the roles of words of quantification, like “ all,” “every” and “some,” in logical statements." I have written, elsewhere, of the marriage of Grice and Barcan-Marcus. Grice was obsessed with all those words -- and MORE. In later years, Grice became obsessed, in work with G. Myro, with '=', and it is with '=' that R. B. Marcus's works relates more. For Grice, '='-statements can be 'relative', in ways that Marcus allows. >An example of a quantified statement is the sentence “All humans are mortal.” >The sentence “Necessarily, humans are mortal” is an example of a modal statement. Grice prefers: Humans MUST be mortal. What's the good of a modality if you don't have a short Anglo-Saxon way to express it? For Grice, the modalities are: OUGHT MUST SHOULD MAY Humans may be mortal. There is something heavy about 'necessarily'. Plus, it confuses, in that it may be taken, wrongly, as a sentence modifier, as in: "Hopefully, we'll find the house." ---- "Quine, ... argued that combining quantifiers and modals produced unintelligible results." Grice and Strawson who hosted Quine at Oxford tried to prove Quine wrong, and they succeeded! "Such issues" as "must" vs. "necessarily" "may seem of small consequence," the NYT explains, "but the need to talk about them is necessarily the meat of philosophical logic." Or pragmatics, as Grice prefers. Grice's disciple, Noel Burton-Roberts, argued for a pragmatic-implicature approach to the square of modalities: che sera sera. What must be must be What may be, must it be too? ---- It ain't necessarily so. What must be, may it be too? --- YES! It must! People use 'must' and 'may' as in a square of opposition, but surely if "You must do it", then, "You MAY do it." ---- "Under her formula, “the second one entails the first one,” Professor Neale explained. “That is, if all humans are necessarily mortal, then necessarily, all humans are mortal.”" ---- I'm glad McEvoy took upon this, and that Palma commented on it. "In other work, Professor Marcus examined the philosophical arguments underpinning moral dilemmas." The wiki entry is pretty complete and adds to the great philosophical lecture in areas OTHER than the Barcan formula. keywords: The Grice-Myro theory of relative identity. Barcan Marcus and Grice. Comments from wiki then: "Ruth Barcan Marcus (b. 1921, d. February 19, 2012) was a philosopher and logician who developed the "Barcan formula". "Barcan Marcus was a pioneering figure in the quantification of modal logic and the theory of direct reference." She wrote seminal essays on identity, essentialism, possibilia, belief, moral conflict as well as some critical historical studies. "Education: B.A., New York University (1941), M.A., Yale University (1942), Ph.D., Yale University (1946). Posts: Professor of philosophy and founding department chair, University of Illinois at Chicago (1962–1970), Professor of philosophy, Northwestern University (1970–1973), Halleck professor of philosophy, Yale University (1973–1991), Professor emerita and senior research scholar, Yale University 1992-2012); Visiting distinguished professor, University of California, Irvine (one quarter each year, 1992–97), Chair of the Board of Officers, American Philosophical Association (1976–83), President, Association for Symbolic Logic (1983–86), President, International Institut de Philosophie (1989–92) and Presidente Honoraire (continuing), Served on various visoring committees for programs and departments, Serves on various editorial boards." "Ruth Barcan Marcus' earliest published work was the publication of the first axiomatic study of modal logic with quantifiers." "These three ground-breaking articles were 1) "A Functional Calculus of First Order Based on Strict Implication", Journal of Symbolic Logic (JSL, 1946), 2) "The Deduction Theorem in a Functional Calculus of First Order Based on Strict Implication" (JSL, 1946), 3) "The Identity of Individuals in a Strict Functional Calculus of Second Order", (JSL, 1947). The three articles are published under Marcus' maiden name: "Ruth C. Barcan." The widely discussed Barcan Formula is introduced as an axiom in QML. "The papers of 1946 and 1947, were the first systems of quantified modal logic, which extended some propositional modal systems of C. I. Lewis to first and second order." "A major accomplishment in the development of 20th century logic. " Lewis gives Marcus special recognition in his "Notes on the Logic of Intension", originally printed in Structure, Method, and Meaning: Essays in Honor of Henry M. Sheffer (New York, 1951). Here, Lewis recognizes Barcan Marcus as the first logician to extend propositional logic as a higher order intensional logic. Barcan Marcus proposed the view in the philosophy of language according to which proper names are what Marcus termed mere "tags". ("Modalities and Intentional Languages" (Synthese, 1961)(and elsewhere). These "tags" are used to refer to an object (the bearer of the name). The meaning of the name is regarded as exhausted by this referential function. This view contrasts for example with late B. A. W. Russell description theory of proper names as well as J. R. Searle's cluster description theory of names which prevailed at the time. This view of proper names (presented in 1962 with Quine as commentator) has been identified by Quentin Smith with the theory of reference given in Saul Kripke's Naming and Necessity. However, in a recent laudatio to Ruth Barcan Marcus, T. Williamson writes: "One of the ideas in them that resonates most with current philosophy of language is that of proper names as mere tags, without descriptive content." "This is not Kripke's idea of names as rigid designators, designating the same object with respect to all relevant worlds, for ‘rigidified’ definite descriptions are rigid designators but still have descriptive content." "Rather, it is the idea, later developed by David Kaplan and others, that proper names are directly referential, in the sense that they contribute only their bearer to the propositions expressed by sentences in which they occur." Marcus formally proved the necessity of identity in 1946 and informally argued for it in 1961 and thereafter thus rejecting the possibility of contingent identity. See Journal of Symbolic Logic, (1947) 12: pp 12–15 Marcus prefers an interpretation where the domain of the interpretation comprises individual entities in the actual world. She also suggests that for some uses an alternative substitutional semantics is warranted. She provides arguments against possibilia. See "Dispensing with Possibilia" (Proceedings of the American Philosophical Association, 1975–76); "Possibilia and Possible Worlds" (Grazer Philosophische Studien, 1985–86). T Marcus defines a consistent set of moral principles as one in which there is some "possible world " in which they are all obeyable. That they may conflict in the actual world is not a mark of inconsistency. As in the case of necessity of identity, there was a resistance to this interpretation of moral conflict. Her argument counts against a widely received view that systems of moral rules are inevitably inconsistent. It is proposed that believing is a relationship of an agent to a possible state of affairs under specified internal and external circumstances. Assenting to a quoted sentence (the disquotation account of belief) is only one behavioral marker of believing. Betting behavior is another. The wholly language-centered account of belief (e.g. Davidson) is rejected. Where an agent behaves as if an impossibility obtained Marcus proposes that under those circumstances the agent, on the disclosure of the impossibility should say that she only claimed to believe an impossibility. In much the same way, when a mathematician discovers that one of his conjectures is false, and since if it is mathematically false it is impossible, he would say he only claimed to believe it. Odd as this proposal is, it is analogous to the widely accepted principle about knowing: if we claim to know P, and P turns out false, we do not say we used to know it, we say we were mistaken in so claiming. The GRICE-MYRO theory of relative identity pertains to Barcan's metaphysics. Aristotelian Essentialism is concerned with properties which Marcus defines in the context of a modal framework. One proposal is that a property is essential if something has it, not everything has it, if something has it then it has it necessarily, and it is not wholly individuating e.g. a natural kind property. It is otherwise claimed by Quine and others that modal logic or semantics is committed to essentialist truths. Marcus argues informally that there are interpretations of some modal systems in which all essentialist claims are false. Terence Parsons later formally proved this result. An alternative to Tarskian (model theoretic) semantics is proposed for some uses where "the truth conditions for quantified formuli are given purely in terms of truth with no appeal to domains of interpretation". (Later called by others "truth value semantics".) She shows that the claim that such a semantics leads to contradictions is false. Such a semantics may be of interest for mathematics e.g. Hartry Field, or for fictional discourse. Objectual quantification is required for interpretation of identity and other metaphysical categories.
