Two puzzles are described: a problem about necessary a posteriori truths and a problem about propositional attitudes with singular propositions as their contents. Two strategies for solving them are compared. The first is the diagonalization strategy, which distinguishes possible worlds that are compatible with what is actually expressed by a given sentential clause from possible worlds that are compatible with what would be expressed by the clause if that possible world were actual. The second strategy is the fragmentation strategy, which represents the intentional states described by sentential clauses as separate nonintegrated representational states. It is argued that these are complementary, not competing, strategies. Both play a role in the solutions to the problems. In conclusion, it is suggested that these strategies can also help to clarify a number of further problems—about self-locating attitudes, about the nature of computation, and about knowledge of phenomenal experience.

Naming And Necessity

In the by now well known talks he gave at Princeton, Saul Kripke claimed that “[t]heoretical identities … are generally identities involving two rigid designators and therefore are examples of the necessary a posteriori.” (Published as “Naming and Necessity,” in G. Harmon and D. Davidson, eds., Semantics of Natural Language (Dordrecht, 1972) 253-355; (hereafter referred to as “NN”; this quote p. 331.) A rigid designator is an expression that designates the same object in all possible worlds when it is used. So Kripke is claiming that ‘Water is H20’ and ‘Heat is the motion of molecules’ are generally identities involving expressions like ‘water’ and ‘the motion of molecules’ which designate the same objects in all possible worlds. If the identity statement is true, both sides designate the same object rigidly, i.e., in all possible worlds, and therefore the statement is necessarily true. On the other hand, whether it is true is determined ultimately by appeal to experience. It follows that if true, the identity is necessary a posteriori.

Necessary Truths

Alvin Plantinga has recently argued that there are certain propositions which are necessary but known only a posteriori. If Plantinga is correct then he has shown that the traditional view that all necessary truths are knowable a priori is false. Plantinga's examples deserve special attention because they differ in important respects from other proposed examples of necessary a posteriori truths. His examples depend on a certain conception of possible worlds and in particular on his conception of the actual world. It will be argued that these examples of necessary a posteriori propositions can be understood in two different ways. According to one way of understanding Plantinga, the propositions turn out to be contingent a posteriori truths, and according to the other way they turn out to be necessary a priori truths. The plausibility of Plantinga's position is due to a confusion between the two possible interpretations.

The Subject

Straipsnyje keliamas klausimas: kokios sąlygos turi būti patenkintos, kad, ištarę sakinį su apibrėžiamąja deskripcija kaip sakinio subjektu, mes išreikštume singuliarinį teiginį (Kaplano prasme). Autorius teigia, kad Wettsteino įsitikinimas, jog teiginio singuliariškumas nustatomas ištarimo metu nurodant apibrėžiamosios deskripcijos referentą, yra nenuoseklus. Straipsnyje siūlomas kitas singuliariškumo kriterijus: teiginys yra singuliarinis, jeigu jame dalyvaujanti apibrėžiamoji deskripcija įvertinama vieninteliame galimame pasaulyje, o jeigu apibrėžiamoji deskripcija turi būti įvertinta daugiau nei vieno galimo pasaulio atžvilgiu, tai teiginys yra bendrasis (general). Šis kriterijus veiksmingas aiškinant kontroversiškus atvejus – kai išreiškiame teisingą singuliarinį teiginį, kurio subjekto dėmuo nedera su apibrėžiamąja deskripcija, pavartota ištartame sakinyje.Pagrindiniai žodžiai: apibrėžiamoji deskripcija, nuoroda, singuliarinis ir bendrasis teiginys, galimų pasaulių semantika. How Do We Use Definite Descriptions to Express Singular Propositions?Evgeny Borisov AbstractThe paper is devoted to the question: under what conditions do we express a singular proposition (in the Kaplanian sense) when uttering a sentence containing a definite description as the subject term. It is argued that Wettstein’s claim that singularity of a proposition is determined by the demonstration of the referent of definite description accompanying the utterance contains an inconsistency. An alternative criterion of singularity is proposed: we express a singular proposition if the definite description in question is to be evaluated at a single possible world, and we express a general one if the definite description in question is to be evaluated at a range of possible worlds. This criterion is effective in explaining controversial cases in which we manage to express a true singular proposition with a subject constituent that does not fit the definite description used in the utterance.Keywords: definite description, reference, singular and general propositions, possible world semantics

Explicit Processing

Dienes' & Perner's proposals are discussed in relation to the distinction between explicit and implicit systems of thinking. Evans and Over (1996) propose that explicit processing resources are required for hypothetical thinking, in which mental models of possible world states are constructed. Such thinking requires representations in which the individuals' propositional attitudes including relevant beliefs and goals are made fully explicit.

Possible World

This paper is concerned with the semantics of the portuguese phrases with the form o mínimo/máximo N (‘the minimum N’) and o mínimo/máximo de N (‘the minimum/maximum of N’). Some nouns may occur in both of these constructions, while others might occur in only one of them, and still other nouns might occur only if accompanied by a modal operator. The proposal is made that these facts can be straightforwardly explained by the hypothesis that the first and the second of these syntactic constructions have, respectively, an extensional and an intensional meaning, together with the fact that some nouns have the same denotation in any possible world, while others denote different sets of entities in different possible worlds.

Vague Existence

Abstract This paper explores a new non-deflationary approach to the puzzle of nonexistence and its cousins. On this approach, we can, under a plausible assumption, express true de re propositions about certain objects that don’t exist, exist indeterminately or exist merely possibly. The defense involves two steps: First, to argue that if we can actually designate what individuates a nonexistent target object with respect to possible worlds in which that object does exist, then we can express a de re proposition about “it”. Second, to adapt the concept of outer truth with respect to a possible world – a concept familiar from actualist modal semantics – for use in representing the actual world.

Errors And Confusions

This chapter discusses Saul Kripke’s treatment of the necessary a posteriori and concomitant distinction between epistemic and metaphysical possibility. It extracts the enduring lessons of his treatment of these matters and disentangles them from errors and confusions that mar some of his most important discussions. It argues that there are two Kripkean routes to the necessary a posteriori—one correct and philosophically far-reaching; the other incorrect, philosophically misleading, and the source of damaging errors that persist to this day. It connects two false principles involved in the second, unsuccessful, route to the necessary a posteriori with the plausible and potentially correct idea that believing a singular proposition that o is F always involves also believing a richer more descriptively informative proposition in which some further property plays a role in the agent’s thoughts about o. It explains why this idea will not save the failed second route to the necessary a posteriori and suggests that it may help reconcile Kripke’s insights with the lessons of Frege’s puzzle.

De Dicto

This chapter explores philosophical issues in metaphysics. It begins by distinguishing between de re and de dicto necessity. All necessity is uniformly de re; there is simply no such thing as de dicto necessity. Indeed, in the glory days of positivism, all necessity was understood as uniformly the same: a necessary truth was always an a priori truth, while contingent truths were always a posteriori. The chapter then assesses the concept of antirealism. Antirealism is always an error theory: there is some sort of mistake or distortion or sloppiness embedded in the usual discourse. The chapter also considers paradoxes, causation, conceptual analysis, scientific mysteries, the possible worlds theory of modality, the concept of a person, the nature of existence, and logic and propositions.

Reductive Theory

This chapter presents and defends the basic tenets of quantum modal realism. The first of these principles, Individualism, states that Everett worlds are metaphysically possible worlds. The converse of this principle, Generality, states that metaphysically possible worlds are Everett worlds. Combining Individualism and Generality yields Alignment, a conjecture about the nature of possible worlds that is closely analogous to Lewisian modal realism. Like Lewisian modal realism, Alignment entails that each possible world is a real concrete individual of the same basic kind as the actual world. These similarities render EQM suitable for grounding a novel theory of the nature of metaphysical modality with some unique properties. Also like Lewisian modal realism, quantum modal realism is a reductive theory: it accounts for modality in fundamentally non-modal terms. But quantum modal realism also has unique epistemological advantages over Lewisian modal realism and other extant realist approaches to modality.
