Aboutness has been studied from any number of angles. Brentano made it the defining feature of the mental. Phenomenologists try to pin down the aboutness-features of particular mental states. Materialists sometimes claim to have grounded aboutness in natural regularities. Attempts have even been made, in library science and information theory, to operationalize the notion. But it has played no real role in philosophical semantics. This is surprising; sentences have aboutness-properties if anything does. Aboutness is the first book to examine through (...) a philosophical lens the role of subject matter in meaning. A long-standing tradition sees meaning as truth-conditions, to be specified by listing the scenarios in which a sentence is true. Nothing is said about the principle of selection--about what in a scenario gets it onto the list. Subject matter is the missing link here. A sentence is true because of how matters stand where its subject matter is concerned. Stephen Yablo maintains that this is not just a feature of subject matter, but its essence. One indicates what a sentence is about by mapping out logical space according to its changing ways of being true or false. The notion of content that results--directed content--is brought to bear on a range of philosophical topics, including ontology, verisimilitude, knowledge, loose talk, assertive content, and philosophical methodology. Written by one of today's leading philosophers, Aboutness represents a major advance in semantics and the philosophy of language. (shrink)

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

Graham Priest presents a ground-breaking account of the semantics of intentional language--verbs such as "believes," "fears," "seeks," or "imagines." Towards Non-Being proceeds in terms of objects that may be either existent or non-existent, at worlds that may be either possible or impossible. The book will be of central interest to anyone who is concerned with intentionality in the philosophy of mind or philosophy of language, the metaphysics of existence and identity, the philosophy of fiction, the philosophy of mathematics, or cognitive (...) representation in AI.

My goal is to reflect on the phenomenon of inadvertent creation and argue that—various objections to the contrary—it doesn’t undermine the view that fictional characters are abstract artifacts. My starting point is a recent challenge by Jeffrey Goodman that is originally posed for those who hold that fictional characters and mythical objects alike are abstract artifacts. The challenge: if we think that astronomers like Le Verrier, in mistakenly hypothesizing the planet Vulcan, inadvertently created an abstract artifact, then the “inadvertent creation” (...) element turns out to be inescapable yet theoretically unattractive. Based on considerations about actually existing concrete objects featured in fictional works (as Napoleon is in Tolstoy’s War and Peace), I argue that independently of one’s stand on mythical objects, admitting fictional characters as abstract artifacts is enough to give rise to the challenge at hand; yet this very point serves to undermine the challenge, indicating that inadvertent creation is not nearly as worrisome as Goodman suggests. Indeed, the inadvertent creation phenomenon’s generality extends far beyond objects of fiction and myth, and I will use this observation to counter a further objection. Taking fictional characters (and mythical objects) to be abstract artifacts therefore remains a viable option. (shrink)

This paper is about intentional identity, the phenomenon of intentional attitudes having a common focus. I present an argument against an approach to explaining intentional identity, defended by Nathan Salmon, Terence Parsons and others, that involves positing exotic objects. For example, those who adopt this sort of view say that when two astronomers had beliefs about Vulcan, their attitudes had a common focus because there is an exotic object that both of their beliefs were about. I argue that countenancing these (...) exotic objects does not help us explain intentional identity. (shrink)

Geach points out that some pairs of beliefs have a common focus despite there being, apparently, no object at that focus. For example, two or more beliefs can be directed at Vulcan even though there is no such planet. Geach introduced the label ‘intentional identity’ to pick out the relation that holds between attitudes in these cases; Geach says that ’[w]e have intentional identity when a number of people, or one person on different occasions, have attitudes with a common focus, (...) whether or not there actually is something at that focus’. In this paper, I propose a novel theory of intentional identity, the triangulation theory, and argue that it has considerable advantages over its principal rivals. My approach centers on agents’ metarepresentational beliefs about what it takes for intentional attitudes to be about particular objects. (shrink)

By a `denoting phrase' I mean a phrase such as any one of the following: a man, some man, any man, every man, all men, the present King of England, the present King of France, the center of mass of the solar system at the first instant of the twentieth century, the revolution of the earth round the sun, the revolution of the sun round the earth. Thus a phrase is denoting solely in virtue of its form. We may distinguish (...) three cases: (1) A phrase may be denoting, and yet not denote anything; e.g., `the present King of France'. (2) A phrase may denote one definite object; e.g., `the present King of England' denotes a certain man. (3) A phrase may denote ambiguously; e.g. `a man' denotes not many men, but an ambiguous man. The interpretation of such phrases is a matter of considerably difficulty; indeed, it is very hard to frame any theory not susceptible of formal refutation. All the difficulties with which I am acquainted are met, so far as I can discover, by the theory which I am about to explain. (shrink)

Definite descriptions occurring within the scopes of psychological verbs provide more puzzles than are traditionally acknowledged. This article presents one puzzle that is particularly intriguing.

In a 2005 paper Ólafur Páll Jónsson presents a puzzle that turns on intentional identity and definite descriptions. He considers eight solutions and rejects them all, thus leaving the puzzle unsolved. In this paper I put forward a solution. The puzzle is this. Little Lotta wants most of all a bicycle for her birthday, but she gets none. Distracted by the gifts she does receive, she at first does not think about the bike. But when seeing her tricycle, she is (...) reminded of the bike. The question is how we are to analyse these two occurrences of ‘the bike’ in the absence of a unique bike that Lotta wants. So the semantics of ‘the bike’ needs to be spelt out, and it must be made explicit what the complements of Lotta’s attitudes are. My analysis shows that the attributer’s usage of ‘the bike’ blurs the distinction between a second-order and a first-order intension (a property concept and a property, respectively). My solution can be summed up in this two-premise argument. (a) In the state-of-affairs S, the property of being a bike is the extension of the property concept the property such that Lotta wants an instance of it more than any other; (b) in S, Lotta does not think about/is reminded of the property that she wants an instance of more than any other; (c) therefore, in S Lotta does not think about/is reminded of the property of being a bike. This solution requires looking beyond the confines of denotational semantics, which all of Jónsson’s eight solution candidates belong to. (shrink)

Wayne Davis presents a highly original approach to the foundations of semantics, showing how the so-called "expression" theory of meaning can handle names and other problematic cases of nondescriptive meaning. The fact that thoughts have parts ("ideas" or "concepts") is fundamental: Davis argues that like other unstructured words, names mean what they do because they are conventionally used to express atomic or basic ideas. In the process he shows that many pillars of contemporary philosophical semantics, from twin earth arguments to (...) the necessity of identity, are unfounded. (shrink)

Reference and Existence, Saul Kripke's John Locke Lectures for 1973, can be read as a sequel to his classic Naming and Necessity. It confronts important issues left open in that work -- among them, the semantics of proper names and natural kind terms as they occur in fiction and in myth; negative existential statements; the ontology of fiction and myth. In treating these questions, he makes a number of methodological observations that go beyond the framework of his earlier book -- (...) including the striking claim that fiction cannot provide a test for theories of reference and naming. In addition, these lectures provide a glimpse into the transition to the pragmatics of singular reference that dominated his influential paper, " Speaker's Reference and Semantic Reference " -- a paper that helped reorient linguistic and philosophical semantics. Some of the themes have been worked out in later writings by other philosophers -- many influenced by typescripts of the lectures in circulation -- but none have approached the careful, systematic treatment provided here. The virtuosity of Naming and Necessity -- the colloquial ease of the tone, the dazzling, on-the-spot formulations, the logical structure of the overall view gradually emerging over the course of the lectures -- is on display here as well.
