Naturalism and the a Priori Penelope Maddy
5 Naturalism and the A Priori PenelopeMaddy The naturalism I aim to practise is a descendantof Quine's. I My goal here is to place this naturalism in what I hope to be an illuminating historical context, to trace the status of the a priori through its various twists and turns, and eventu- ally to draw some tentative conclusions about the naturalistic status of the a priori. To do this, I first return to Kant. While it's surely no surprise that an examination of the a priori should start from Kant, perhapshis relevanceto natu- ralism is less obvious. Let me begin, then, with an introductory word on that connection. Though my naturalism differs from Quine's in a couple of significant ways, these disagreements won't matter until the very end. so we can begin with Quine's leading idea: the 'abandonmentof the goal of a first philosophy' (Quine 1975: 72). The interconnectionsbetween Quine and Carnap will take centre stage later, but for now we needonly note that the bare rejection of first philosophy can be seen as evolving out of Carnap's classification of many traditional metaphys- ical claims as 'pseudo-statement[s] without cognitive content' (Carnap 1950: 250). Carnap's idea is that legitimate scientific questions, 'theoretical questions', are asked within the linguistic framework of scientific language,with its associ- ated principles of evidence; in contrast, metaphysical pseudo-questionsare posed outside of all linguistic frameworks; perhaps as preamble to the adoption of a linguistic framework, as such, they are asked without the backing of associated evidential rules that would make them answerable,and indeed, that would give them sense. -

Logical Foundations: Personal Perspective
LOGICAL FOUNDATIONS: PERSONAL PERSPECTIVE YURI GUREVICH Abstract. This is an attempt to illustrate the glorious history of logical foundations and to discuss the uncertain future. Apologia1. I dread this scenario. The deadline is close. A reminder from the Chief Editor arrives. I forward it to the guest author and find out that they had a difficult real-world problem, and the scheduled article is not ready. I am full of sympathy. But the result is all the same: the article is not there. That happened once before in the long history of this column, in 2016. Then the jubilee of the 1966 Congress of Mathematicians gave me an excuse for a micro-memoir on the subject. This time around I decided to repurpose a recent talk of mine [2]. But a talk, especially one with ample time for a subsequent discussion, is much different from a paper. It would normally take me months to turn the talk into a paper. Quick repurposing is necessarily imperfect, to say the least. Hence this apologia. 1. Prelude What should logic study? Of course logic should study deductive rea- soning where the conclusions are true whenever the premises are true. But what other kinds of reasoning and argumentation should logic study? Ex- perts disagree about that. Typically it is required that reasoning be correct arXiv:2103.03930v1 [cs.LO] 5 Mar 2021 in some objective sense, so that, for example, demagoguery is not a subject of logic. My view of logic is more expansive. Logic should study argumentation of any kind, whether it is directed to a narrow circle of mathematicians, the twelve members of a jury, your family, your government, the voters of your country, the whole humanity. -

Miriam Butt and Tracy Holloway King Functional Identity and Resource-Sensitivity in Control Ash Asudeh Stanford University and Xerox PARC Proceedings of the LFG00 Conference University of California, Berkeley Miriam Butt and Tracy Holloway King (Editors) 2000 CSLI Publications http://csli-publications.stanford.edu/ 2 1 Introduction1 Glue semantics provides a semantics for Lexical Functional Grammar (LFG) that is expressed using linear logic (Girard, 1987; Dalrymple, 1999) and provides an interpretation for the f(unctional)-structure level of syntactic representation, connecting it to the level of s(emantic)-structure in LFG’s parallel projection archi- tecture (Kaplan, 1987, 1995). Due to its use of linear logic for meaning assembly, Glue is resource-sensitive: semantic resources contributed by lexical entries and resulting f-structures must each be used in a successful proof exactly once. In this paper, I will examine the tension between a resource-sensitive semantics which interprets f-structures and structure-sharing in f-structures as expressed by functional control resulting from lexical functional identity equations. -
RELATIONAL NOUNS, PRONOUNS, and Resumptionw Relational Nouns, Such As Neighbour, Mother, and Rumour, Present a Challenge to Synt
Linguistics and Philosophy (2005) 28:375–446 Ó Springer 2005 DOI 10.1007/s10988-005-2656-7 ASH ASUDEH RELATIONAL NOUNS, PRONOUNS, AND RESUMPTIONw ABSTRACT. This paper presents a variable-free analysis of relational nouns in Glue Semantics, within a Lexical Functional Grammar (LFG) architecture. Rela- tional nouns and resumptive pronouns are bound using the usual binding mecha- nisms of LFG. Special attention is paid to the bound readings of relational nouns, how these interact with genitives and obliques, and their behaviour with respect to scope, crossover and reconstruction. I consider a puzzle that arises regarding rela- tional nouns and resumptive pronouns, given that relational nouns can have bound readings and resumptive pronouns are just a specific instance of bound pronouns. The puzzle is: why is it impossible for bound implicit arguments of relational nouns to be resumptive? The puzzle is highlighted by a well-known variety of variable-free semantics, where pronouns and relational noun phrases are identical both in category and (base) type. I show that the puzzle also arises for an established variable-based theory. I present an analysis of resumptive pronouns that crucially treats resumptives in terms of the resource logic linear logic that underlies Glue Semantics: a resumptive pronoun is a perfectly ordinary pronoun that constitutes a surplus resource; this surplus resource requires the presence of a resumptive-licensing resource consumer, a manager resource. Manager resources properly distinguish between resumptive pronouns and bound relational nouns based on differences between them at the level of semantic structure. The resumptive puzzle is thus solved. The paper closes by considering the solution in light of the hypothesis of direct compositionality. -
29 Alethic Modal Logics and Semantics
29 Alethic Modal Logics and Semantics GERHARD SCHURZ 1 Introduction The first axiomatic development of modal logic was untertaken by C. I. Lewis in 1912. Being anticipated by H. McCall in 1880, Lewis tried to cure logic from the ‘paradoxes’ of extensional (i.e. truthfunctional) implication … (cf. Hughes and Cresswell 1968: 215). He introduced the stronger notion of strict implication <, which can be defined with help of a necessity operator ᮀ (for ‘it is neessary that:’) as follows: A < B iff ᮀ(A … B); in words, A strictly implies B iff A necessarily implies B (A, B, . for arbitrary sen- tences). The new primitive sentential operator ᮀ is intensional (non-truthfunctional): the truth value of A does not determine the truth-value of ᮀA. To demonstrate this it suf- fices to find two particular sentences p, q which agree in their truth value without that ᮀp and ᮀq agree in their truth-value. For example, it p = ‘the sun is identical with itself,’ and q = ‘the sun has nine planets,’ then p and q are both true, ᮀp is true, but ᮀq is false. The dual of the necessity-operator is the possibility operator ‡ (for ‘it is possible that:’) defined as follows: ‡A iff ÿᮀÿA; in words, A is possible iff A’s negation is not necessary. Alternatively, one might introduce ‡ as new primitive operator (this was Lewis’ choice in 1918) and define ᮀA as ÿ‡ÿA and A < B as ÿ‡(A ŸÿB). Lewis’ work cumulated in Lewis and Langford (1932), where the five axiomatic systems S1–S5 were introduced. -

Principles of knowledge, belief and conditional belief Guillaume Aucher 1 Introduction Elucidating the nature of the relationship between knowledge and belief is an old issue in epistemology dating back at least to Plato. Two approaches to addressing this problem stand out from the rest. The first consists in providing a definition of knowledge, in terms of belief, that would somehow pin down the essential ingredient binding knowledge to belief. The second consists in providing a complete characterization of this relationship in terms of logical principles relating these two notions. The accomplishement of either of these two objectives would certainly contribute to solving this problem. The success of the first approach is hindered by the so-called ‘Gettier problem’. Until recently, the view that knowledge could be defined in terms of belief as ‘justified true belief’ was endorsed by most philosophers. -

Existence and Reference in Medieval Logic
GYULA KLIMA EXISTENCE AND REFERENCE IN MEDIEVAL LOGIC 1. Introduction: Existential Assumptions in Modern vs. Medieval Logic “The expression ‘free logic’ is an abbreviation for the phrase ‘free of existence assumptions with respect to its terms, general and singular’.”1 Classical quantification theory is not a free logic in this sense, as its standard formulations commonly assume that every singular term in every model is assigned a referent, an element of the universe of discourse. Indeed, since singular terms include not only singular constants, but also variables2, standard quantification theory may be regarded as involving even the assumption of the existence of the values of its variables, in accordance with Quine’s famous dictum: “to be is to be the value of a variable”.3 But according to some modern interpretations of Aristotelian syllogistic, Aristotle’s theory would involve an even stronger existential assumption, not shared by quantification theory, namely, the assumption of the non-emptiness of common terms.4 Indeed, the need for such an assumption seems to be supported not only by a number of syllogistic forms, which without this assumption appear to be invalid, but also by the doctrine of Aristotle’s De Interpretatione concerning the logical relationships among categorical propositions, commonly summarized in the Square of Opposition. For example, Aristotle’s theory states that universal affirmative propositions imply particular affirmative propositions. But if we formalize such propositions in quantification theory, we get formulae between which the corresponding implication does not hold. So, evidently, there is some discrepancy between the ways Aristotle and quantification theory interpret these categoricals. -
Probabilistic Semantics for Modal Logic
Probabilistic Semantics for Modal Logic By Tamar Ariela Lando A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Philosophy in the Graduate Division of the University of California, Berkeley Committee in Charge: Paolo Mancosu (Co-Chair) Barry Stroud (Co-Chair) Christos Papadimitriou Spring, 2012 Abstract Probabilistic Semantics for Modal Logic by Tamar Ariela Lando Doctor of Philosophy in Philosophy University of California, Berkeley Professor Paolo Mancosu & Professor Barry Stroud, Co-Chairs We develop a probabilistic semantics for modal logic, which was introduced in recent years by Dana Scott. This semantics is intimately related to an older, topological semantics for modal logic developed by Tarski in the 1940’s. Instead of interpreting modal languages in topological spaces, as Tarski did, we interpret them in the Lebesgue measure algebra, or algebra of measurable subsets of the real interval, [0, 1], modulo sets of measure zero. In the probabilistic semantics, each formula is assigned to some element of the algebra, and acquires a corresponding probability (or measure) value. A formula is satisfed in a model over the algebra if it is assigned to the top element in the algebra—or, equivalently, has probability 1. The dissertation focuses on questions of completeness. We show that the propo- sitional modal logic, S4, is sound and complete for the probabilistic semantics (formally, S4 is sound and complete for the Lebesgue measure algebra). We then show that we can extend this semantics to more complex, multi-modal languages. In particular, we prove that the dynamic topological logic, S4C, is sound and com- plete for the probabilistic semantics (formally, S4C is sound and complete for the Lebesgue measure algebra with O-operators).
