Tracking the Real: Through Thick and Thin
by Stathis Psillos
In this paper, I examine Azzouni's tracking requirement and its use as a normative constraint on theories about objects which we take as real. I focus on what he calls 'thick epistemic access' and argue that there is a logical-conceptual sense in which thick access to the real presupposes thin access to it. Then, I move on to advance an alternative-Sellarsian-way to ontic commitment and show that (a) it is better than Azzouni's, and (b) it can accommodate thick epistemic access as a bonus. Finally, I try to defend the Quinean theoretical virtues against some of Azzouni's objections.

Given the sentence {1} below:
{1} During refections a llama dawdles less than an aardvark.
A user of English should be able to understand it, at least in part, even if he does not know what a llama or an aardvark is or what to dawdle and refection mean. Or shouldn't he?

Linguistic Understanding and Belief
Discussion of Dean Pettit's Why Knowledge is Unnecessary for Understanding Language, Mind 111
by Steven Gross
In a recent paper, Dean Pettit argues against the view that understanding a bit of language consists in the possession of propositional knowledge of its meaning--what he labels the epistemic view of linguistic understanding. His objection to the epistemic view is that it entails that it's necessary to understand a bit of language that one possess propositional knowledge of its meaning, but this necessity claim is false: for linguistic understanding, unlike knowledge, does not fail in Gettier cases, does not require epistemic warrant, and does not require belief; in supplying cases demonstrating this, one supplies cases of linguistic understanding without such knowledge. Pettit's arguments, if successful, thus establish the falsity of a variety of weaker claims in addition to that of the epistemic view. They would establish, for example, the falsity of necessity claims as weak as the weakest modality allowing the possibility of his cases. Further, the third argument--that linguistic understanding does not require belief that the bit of language means such-and-such--establishes, if successful, the falsity of parallel claims concerning belief. Given the case Pettit appeals to in his third argument, this would include the falsity of the claim that belief about an expression's meaning is nomologically necessary for a human speaker to possess linguistic understanding of it. Pettit's case thus poses a challenge to prominent empirical accounts of semantic competence that advert to states with such propositional content.

On the Notion of Substitution
Marcel Crabbe
We consider a concept of substitutive structure, called "logos", in order to study simple substitution, independently of formal or programming languages. We provide a definition of simultaneous substitution in an arbitrary logos and use it to prove a completeness theorem expressing that the equational properties of the usual substitution can be proved from the logos axioms only.

Phase structure, Phrase structure,
and Quantification
by Jonny Butler
Source: Semantics Archive
I combine two areas of investigation in current syntactic literature:
(1) the structure of the clause contains layers of hierarchically ordered quantificational heads, situated above the temporal and verbal fields (Beghelli & Stowell 1997);
(2) the clause is built in phases -- subclausal building blocks with parallel properties.
I claim these two threads should be tied together, in that phases should be defined in terms of such quantificational layers. Precisely, I claim a phase consists of some property denoting head H, topped by some associated `little' head(s) h (as v over V) -- this, the phase domain -- surmounted by a CP layer -- the phase edge -- that encodes quantificational information to close off domain-internal variables. This derives a V phase, C > v > V (corresponding to the standard vP phase); a T phase, C > t > T, (the standard CP phase); also an N phase (DP/QP), C > n > N, where C = D. Treating phases in these terms derives the major facets of orthodox phase theory, but in a much more elegant, less stipulative way.
Cyclicity, for example, is captured as an expected property of the system, rather than by the stipulated Phase Impenetrability Condition of Chomsky (2000). Evidence for this reinterpretation of phase theory is adduced from:
(1) The interpretation of QPs, treated uniformly like Heim (1982) indefinites: so any QP introduces a restricted variable, subject to closure by intra-clausal quantificational heads analogous to Heim's 9-closure operator.
(2) The structure and interpretation of temporal predicates, T/Perf/Prog, treated as embedding situation-denoting phases as internal argument, and introducing a situation variable, closed off by their own CP, as external argument.
(3) The interpretation and scope behaviour of modality, defined as quantification over possible situations: syntactically expressed as CP-/edge-level quantificational
heads operating over domain-level situation variables.

MEASURES AND INDEFINITES
by Hana Flip
Source: Semantics Archive
In this paper I explore the function of prefixes as verb-internal operators that have distinct semantic effects on the interpretation of nominal arguments. I will focus on the Russian prefix n a - used in its cumulative sense of approximately a {relatively/sufficiently/exceedingly} large quantity (of), and to a lesser extent on its converse, namely, the delimitative/attenuative po-. Such prefixes have one notable and neglected property: namely, they systematically require that nominal arguments targeted by them have a non-specific indefinite interpretation, regardless whether the verb they form is perfective or imperfective. I will argue that the semantics of such prefixes is to be assimilated to that of measure phrases and propose an additional novel role for them: namely, as morphological markers of a particular mode of composition that is available for semantically incomplete nominal arguments that have a non-specific indefinite interpretation. If this analysis is correct, then it precludes measure prefixes in Slavic languages from being analyzed as overt morphological exponents of the perfective operator, contrary to the majority of current analyses which take this to be the main or the only function of Slavic prefixes as a whole class. Instead, this analysis enforces the view on which measure prefixes function as modifiers of eventuality types expressed by `aspectless' verbal predicates.

EVENT-STRUCTURE AND THE INTERNALLY-HEADED RELATIVE CLAUSE CONSTRUCTION IN KOREAN AND JAPANESE
by Min-Joo Kim
Source: Sematics Archive
This dissertation investigates how syntactic, semantic, and pragmatic factors interact to produce the Internally-Headed Relative Clause (IHRC) construction in Korean and Japanese. The IHRC construction differs from the more familiar Externally-Headed Relative Clause (EHRC) construction in several ways. First, unlike an EHRC, an IHRC?s content restricts the content of the matrix clause rather than that of the semantic head. Second, its interpretation is heavily influenced by the discourse context in ways not seen with the EHRC. Third, unlike the head of an EHRC, the head of an IHRC does not correspond to any overt syntactic phrase and hence needs to be determined by language users based on the relative clause?s content, the matrix predicate?s semantics, and the discourse context.
The literature offers an abundance of sensitive analyses of the IHRC construction, but it leaves two central questions unanswered: what determines the interpretation of the construction? And, if pragmatic principles play a role, how do they interact with the morphosyntax and the semantics? I answer these questions with an event-based semantic analysis. I show that the construction?s interpretation is determined partly by grammatical factors (e.g., the embedded clause?s aspect and the matrix predicate?s semantics) and partly by pragmatic factors (the discourse context and the discourse participants? world knowledge). In particular, I isolate two sources of the semantic variability of the construction.
First, the matrix clause contains a pronominal definite description, whose denotation contains a free relation variable. The value of this variable is determined by the embedded clause?s event structure, the matrix predicate?s semantics, and the discourse context.
Second, the relative operator that occurs in this construction connects the content of the embedded clause with that of the matrix clause, establishing either a temporal or a causal relation between them, depending on whether the embedded clause describes a temporary state or a permanent state.
This study establishes important connections between the semantics of a definite description and event structure, thereby solving a particularly challenging formal-linking problem, one that afflicts existing E-type pronoun analyses of the IHRC construction. In addition, it provides a constrained but flexible interpretive mechanism for the construction, eliminating the need for many of the extra-grammatical constraints that characterize existing treatments.

Combining possibility and knowledge
By Alexandre Costa-Leite
Source: CLE
This paper is an attempt to define a new modality with philosophical interest by combining the basic modal ingredients of possibility and knowledge. This combination is realized via product of modal frames so as to construct a knowability modality, which is a bidimensional constructor of arity one defined in a two-dimensional modal frame. A semantical interpretation for the operator is proposed, as well as an axiomatic system able to account for inferences related to this new modality. The resulting logic for knowability LK is shown to be sound and complete with respect to its class of modal-epistemic product models.

Context Dependence and Compositionality
Francis Jeffry Pelletier
Source: Language & Mind
Some utterances of sentences such as `Every student failed the midterm exam' and `There is no beer' are widely held to be true in a conversation despite the facts that not every student in the world failed the midterm exam and that there is, in fact, some beer somewhere. For instance, the speaker might be talking about some particular course, or about his refrigerator. Stanley and Szab?-- (in Mind and Language v. 15, 2000) consider many different approaches to how contextual information might give meaning to these `restricted quantifier domains', and find all of them but one wanting. The present paper argues that their considerations against one of these other theories, considerations that turn on notions of compositionality, are incorrect.

Inconsistency without Contradiction
by Achille C. Varzi
Source: Notre Dame J. Formal Logic
Lewis has argued that impossible worlds are nonsense: if there were such worlds, one would have to distinguish between the truths about their contradictory goings-on and contradictory falsehoods about them; and this--Lewis argues--is preposterous. In this paper I examine a way of resisting this argument by giving up the assumption that `in so-and-so world' is a restricting modifier which passes through the truth-functional connectives. The outcome is a sort of subvaluational semantics which makes a contradiction 'A and not-A' false even when both 'A' and 'not-A' are true, just as supervaluational semantics makes a tautology 'A and not-A' true even when neither 'A' and 'not-A' are.

Monotonicity in Opaque Verbs
by Thomas Ede Zimmermann
Source: Semantics Archive
In this paper I will defend a quantificational semantic analysis of the unspecific readings of opaque transitive verbs, i.e. verbs that induce a certain kind of ambiguity with respect to their direct object position:
(0a) I owe you a horse.
(0b) Ernest is looking for a lion.
(0c) Tom's horse resembles a unicorn.
(0d) John hired an assistent.
Unlike sentences with ordinary, transparent verbs and indefinite objects, each of (0a-d) allows for a reading that cannot be described in terms of existential quantification over the individuals in the extension of the respective noun. Rather, it seems as though the domain of quantification is shifted, as the following naive paraphrases (of the relevant readings) indicate:
(0'a) I owe you an arbitrary horse.
(0'b) Ernest is looking for an intentional lion.
(0'c) Tom's horse resembles a generic unicorn.
(0'd) John hired a would-be assistent.
Neither arbitrary horses, nor intentional lions, nor generic unicorns are animals, and would-be assistents do not have to be assistents. In fact, one may well wonder just what sort of objects the paraphrases in (0') are supposed to be about. Given their dubious ontological status, an analysis of (0) that can do without them ought to be preferrable to one along the lines of (0') - ceteris paribus. Such analyses have been developed, based on the observation that opaque verbs tend to express propositional attitudes (in a broad sense). Following them, instead of trying to make literal sense of (0'), it is more worthwhile to explore the (admittedly rough) paraphrases under (0") instead, thereby reducing the strangeness of (0) to an interaction of the lexical meaning of the opaque verb and the ordinary meaning of the indefinite as existentially quantifying over the extension of its head noun:
(0"a) I am obliged to see to it that it will be the case that I give you a horse.
(0"b) Jones is trying for it to be the case that Jones finds a lion.
(0"c) Given its outward appearance, Tom's horse could be a unicorn.
(0"d) Jones saw to it that someone would be an assistant.
And semantic analysis does not have to stop here.

The debate goes on: how many truth-values are necessary in Logic?
Truth, Falsity and Borderline Cases
by Miroslava Andjelkovi & Timothy Williamson
According to the principle of bivalence, truth and falsity are jointly exhaustive and mutually exclusive options for a statement. It is either true or false, and not both, even in a borderline case.
That highly controversial claim is central to the epistemic theory of vagueness, which holds that borderline cases are distinguished by a special kind of obstacle to knowing the truth -value of the statement. But this paper is not a defence of the epistemic theory. If bivalence holds, it presumably does so as a consequence of what truth and falsity separately are.
One may therefore expect bivalence to be derivable from a combination of some principles characterizing truth and other principles characterizing falsity. Indeed, such derivations are easily found. Their form will of course depend on the initial characterizations of truth and falsity, and not all such characterizations will permit bivalence to be derived. In this paper we focus on the relation between its derivability and some principles about truth and falsity . We will use borderline cases for vague expressions as primary examples of an urgent challenge to bivalence.

Indefinites and the Operators they Depend on:
From Japanese to Salish
by Angelika Kratzer
Source: The Semantics Archive
(...)
Irene Heim (1982) and Hans Kamp (1981) took up Partee's challenge and proposed theories that simultaneously accounted for the quantificational and discourse reference properties of indefinites. They argued that the quantificational behavior of indefinites was an illusion. It derived from overt or non-overt operators present in semantic representations, or alternatively, from the mechanics of the semantic interpretation procedure itself. According to Heim and Kamp, indefinites introduced mere variables with conditions attached to them into semantic representations. Much of the discussion that followed centered around the question whether indefinites did or did not have quantificational force. The dynamic theories of Groenendijk and Stokhof (1990) and Dekker (1993) maintained that they did, but argued for an unorthodox way of extending their binding domain.
Stephen Berman (1987) observed that within a situation semantics, a standard quantificational theory of indefinites did not conflict with their discourse reference properties, since donkey pronouns could now again be analyzed as disguised definite descriptions, as Robin Cooper (1979) had originally proposed. This idea was further developed in Heim's (1990) paper on E-type pronouns and donkey anaphora. At that point, it looked like a standard quantificational analysis of indefinites was right after all.
