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) | |
This essay argues for a 'relationist' treatment of intentional identity sentences like (1) "Hob believes that a witch blighted Bob's mare and Nob believes that she killed Cob's sow" (Geach 1967). According to relationism, facts of the form "a believes that p and b believes that q" are not in general reducible to facts of the form "c believes that r". We first argue that extant, non-relationist treatments of intentional identity are unsatisfactory, and then go on to motivate and explore (...) a relationist alternative in some detail. We show that the general thesis of relationism can be directly motivated via cases already discussed in the literature, and then develop a particular version of relationism couched in the possible worlds framework. The resulting theory avoids the problems facing its non-relationist rivals, and yields a natural account of the truth-conditions of (1), truth-conditions which can be generated in a compositional manner by a version of dynamic semantics. The theory also helps us to cleanly separate semantic questions about intentional identity from metasemantic ones. (shrink) | |
Some intentional attitudes (beliefs, fears, desires, etc.) have a common focus in spite of there being no object at that focus. For example, two beliefs may be about the same witch even when there are no witches, different astronomers had beliefs directed at Vulcan, even though there is no such planet. This relation of having a common focus, whether or not there is an actual concrete object at that focus, is called intentional identity. In the first part of this thesis (...) I develop a new theory of intentional identity, the triangulation theory, and argue that it has significant advantages over the extant theories of intentional identity in the literature. Empty attitudes (attitudes that are not, prima facie, about anything that exists) will serve as useful cases for testing theories of intentional identity. -/- In the second part, I put the theory developed in the first part to work. I use triangulation theoretic tools to shed light on other debates about intentional attitudes. Some issues to which intentional identity are relevant are the debate about the content of intentional attitudes, the issue of whether or not we need to appeal to external constraints on the content of intentional attitudes, how we should understand the agreement and disagreement of attitudes, how we should construe communication and how we ought to solve Kripke’s puzzle about belief. The second part of this thesis also motivates a broadly internalist and individualistic approach to the con-tent of intentional attitudes; it turns out that if we take a closer look at the narrowly construed psychological states of agents we find materials that allow us to make sense of phenomena usually associated with externalist constraints on the content of attitudes (such as causal constraints and eligibility constraints) in a new way.

The problem of intentional identity, as originally offered by Peter Geach, says that there can be an anaphoric link between an indefinite term and a pronoun across a sentential boundary and across propositional attitude contexts, where the actual existence of an individual for the indefinite term is not presupposed. In this paper, a semantic resolution to this elusive puzzle is suggested, based on a new quantified intensional logic and game-theoretic semantics (GTS) of imperfect information. This constellation leads to an expressive (...) intensional language with a property of informational independence, argued to produce a purely semantic explication to intentional identity statements. One consequence is that various extra-logical and pragmatic factors become of secondary concern; it is possible to solve the puzzle by logico-semantic methods, albeit somewhat radically renewed ones.

It is generally agreed that some anaphoric pronouns with quantifier antecedents occur outside the syntactic scope of their antecedents. First, there is “donkey anaphora,” of both the conditional and relative clause varieties:If Sarah owns a donkey, she beats it.Every woman who owns a donkey beats it.Without going through the details, let me just assert that there is good reason to think that the pronouns in and do not occur in the syntactic scope of the quantifier’ a donkey’. A second sort (...) of case in which a pronoun with a quantified antecedent occurs outside the syntactic scope of its quantifier antecedent is one in which the pronoun and its antecedent occur in different sentences.A second sort of case in which a pronoun with a quantified antecedent occurs outside the syntactic scope of its quantifier antecedent is one in which the pronoun and its antecedent occur in different sentences. Examples of such “discourse anaphora,” from the very simple to the slightly complex, include:A man is following Sarah. He is from the Internal Revenue Service.A man is following Sarah. Melanie believes he is from the Internal Revenue Service.It is possible that several students flunked at most five exams. Melanie believes they didn’t study for them.Suzi ought to apologize to most of Ann’s dinner guests. It is certain that she insulted them. But it is unclear whether they noticed.

This work analyzes Peter Geach's problem of intentional identity, viz. adequately formalizing the sentence "Hob thinks a witch has blighted Bob's mare and Nob wonders whether she killed Cob's sow" and other sentences like it. First, Geach's problem is presented, and then Geach's original formalization proposals, and his own reasons for rejecting them, are presented and discussed. Next, the solutions proposed by various philosophers and linguists are presented and analyzed in detail. All are shown to be either inadequate or incomplete. (...) As a result, the standard objections to one particular solution, the pronoun of laziness solution, are re-examined and shown to have problematic consequences. Finally, a modified pronoun of laziness solution that avoids the standard objections is presented and defended. (shrink) |
