In "Actualism or Possibilism?" (Philosophical Studies, 84 (2-3), December 1996), James Tomberlin develops two challenges for actualism. The challenges are to account for the truth of certain sentences without appealing to merely possible objects. After canvassing the main actualist attempts to account for these phenomena, he then criticizes the new conception of actualism that we described in our paper "In Defense of the Simplest Quantified Modal Logic" (Philosophical Perspectives 8: Philosophy of Logic and Language, Atascadero, CA: Ridgeview, 1994). We respond (...) to Tomberlin's criticism by showing that we wouldn't analyze the problematic claim (e.g., "Ponce de Leon searched for the fountain of youth") in the way he suggests. (shrink)

Along with a well-honoured tradition, we will accept that intentionality is at least a property a thought holds necessarily, i.e., in all possible worlds that contain it; more specifically, a necessary relation, namely the relation of existential dependence of the thought on its intentional object. Yet we will first of all try to show that intentionality is more than that. For we will claim that intentionality is an essential property of the thought, namely a property whose predication to the thought (...) is true in virtue of the identity, or nature, of such a thought. More particularly, for us intentionality will again be a relation, yet a relation of ontological dependence of the thought on its intentional object; specifically, the relation for the thought of being constituted by its object. Moreover, we will try to show that if intentionality is such a constitutive relation for the thought that has it, certain metaphysical consequences ensue. First, an objectual thought, a thought whose content basically consists in its intentional object, is nothing but that object in a certain cogitative modality, or, which is the same, as playing a certain motivational role for the subject entertaining the thought itself (at a certain time). Second, if an objectual thought is nothing but an intentional object in a cogitative modality, such a thought, not only as a type, but also as a token, is an abstract entity. More specifically, an objectual thought-type, an abstract object par excellence, is indeed instantiated by objectual thought-tokens which are again abstract particulars, yet of a specific kind: namely, tropes of a relational sort depending for their existence on their bearers (and possibly also on their temporal location).

In his recently published paper, ‘The Nature of Possibility,’ David Armstrong presents an account of possibility which, he correctly claims, is partly an elaboration of the early Wittgenstein's. Both are combinatorialists. That is to say, both hold that there is a fixed ontology of individuals, properties and relations whose combinations determine the range of all possible states of affairs, and therewith the range of all those totalities of states of affairs which they call possible worlds.But Armstrong's account, I believe, is (...) fatally flawed in ways that Wittgenstein's isn't. And this, I shall argue, is mainly because Armstrong is both an actualist, whose fixed ontology is one of actual individuals, properties and relations, and a reductionist, who tries to reduce the notion of possibility to that of ߢallߣ their combinations. Armstrong seems to think that Wittgenstein at least shares his actualism, and perhaps even his reductionism. (shrink)

Although both belong to the domain of the nonexistent, there is an ontological distinction between ficta and possibilia. Ficta are a particular kind of abstract objects, namely constructed abstract objects which generically depend on authors for their subsistence. Moreover, they are essentially incomplete entities, in that they are correlates of finite sets of properties. - On the other hand, possibilia are concrete objects. Being a possible object is indeed being an entity that might have existed, that is, that might have (...) been involved in the causal order. Besides, as an object existent in this sense may legitimately be qualified as complete, the incompleteness which pertains to possible objects is contingent, in that it regards them only with respect to the possible worlds in which they do not exist. This ontological distinction has a semantic correlate: whereas names for possibilia are full-fledged directly referential terms, names for ficta are synonymous with de facto rigid descriptions of a complex sort.

Alcuni anni or sono, poco dopo l’uscita dell’edizione italiana di Lexical Competence, mi è capitato di pubblicare un breve articolo in cui analizzavo e criticavo certe tesi sostenute da Diego Marconi nel suo libro. L’articolo era seguito, nello stesso numero della rivista, da una risposta di Marconi alla quale non ho mai replicato. La presente nota vuole essere, più che una replica tardiva, una riconsiderazione complessiva di quella discussione. La strategia argomentativa che avevo adottato a...

A new theory of identity statements is put forward which appeals to a basic distinction between two notions of identity, i.e. strict and loose identity. The former is the traditional necessary relation of an object with the object itself, whereas the latter is a contingent relation of reduction of some (at least two) possible unactual objects to a possible actual object. By appealing to strict identity, one can maintain that some tokenings of identity sentences express a semantic content which is (...) both knowable apriori only and a necessary proposition. By appealing to loose identity instead, one can maintain that other tokenings of identity sentences express a semantic content which is both knowable a posteriori only and a contingent proposition.

In recent works, Chomsky has once more endorsed a computational view of rulefollowing, whereby to follow a rule is to operate certain computations on a subject’s mental representations. As is well known, this picture does not conform to what we may call the grammatical conception of rule-following outlined by Wittgenstein, whereby an elucidation of the concept of rule-following is aimed at by isolating grammatical statements regarding the phrase ‘to follow a rule’. As a result, Chomskyan and Wittgensteinian treatments of topics (...) immediately connected with rule-following, namely linguistic competence and understanding, are utterly different from one another. There are two possible stances that computationalists like Chomsky may adopt with regard to the discrepancy between the two aforementioned modes of dealing with rule-following, namely a conciliatory and a non-conciliatory attitude. According to the former attitude, grammatical remarks on and computationallyoriented theories of rule-following investigate one and the same topic although admittedly at different levels, namely a conceptual and an empirical one. According to the latter attitude, grammatical remarks are just a preliminary step in the investigation of rule-following which scientific advancement, presently represented by computationally-oriented theories on this matter, is well entitled to put aside. In what follows, however, I will try to show that both stances are problematic. The conciliatory attitude simply does not work, for it hardly copes with the fact that the concept of rule-following does not supervene, even weakly, on the property of rule-following, namely the property instantiated in the mental/cerebral phenomena that computationally-oriented theories of rule-following study. To take the contrary attitude, on the other hand, is to end up with another disappointing result, namely that the computational treatment of rule-following ultimately deals with something different from that which we wished to gain knowledge of when we began our inquiry into rule-following..
