Can humans and artificial intelligences share concepts and communicate? Making AI Intelligible shows that philosophical work on the metaphysics of meaning can help answer these questions. Herman Cappelen and Josh Dever use the externalist tradition in philosophy to create models of how AIs and humans can understand each other. In doing so, they illustrate ways in which that philosophical tradition can be improved. The questions addressed in the book are not only theoretically interesting, but the answers have pressing practical implications. (...) Many important decisions about human life are now influenced by AI. In giving that power to AI, we presuppose that AIs can track features of the world that we care about (for example, creditworthiness, recidivism, cancer, and combatants). If AIs can share our concepts, that will go some way towards justifying this reliance on AI. This ground-breaking study offers insight into how to take some first steps towards achieving Interpretable AI. (shrink)

ABSTRACT Recently, in a series of papers, Joshua Spencer has introduced, defended, and developed a modified version of Neo-Russellianism, namely Plenitudinous Russellianism, according to which there are structurally identical but numerically distinct singular Russellian propositions. PR claims to provide novel semantic solutions to all the major problems that NR faces with no radical revision in NR. In this paper, I introduce a semantic puzzle for PR: the view leads to the violation of the principle of substitutivity of co-referential proper names (...) within simple ‘that’-clauses. I consider different responses to my argument, and show that none of them is fully satisfactory for the Russellian. I conclude that PR needs to depart from NR more radically. RÉSUMÉ Récemment, Joshua Spencer a publié une série d'articles où il expose, défend et développe une version modifiée du Néo-Russellianisme, appelée Russellianisme de plénitude, selon laquelle il y a des propositions Russelliennes singulières structurellement identiques mais numériquement distinctes. Ce Russellianisme de plénitude prétend apporter de nouvelles solutions sémantiques à tous les problèmes majeurs auxquels le NR se confronte, sans pour autant procéder à une révision radicale du NR. Dans cet article, je mettrai le PR face à un casse-tête : cette vision mène à la violation du principe de substitution des noms propres co-référentiels au sein des subordonnées complétives simples. Je tâcherai de considérer différentes réponses à mon argument et de montrer qu'aucune d'entre elles n'est pleinement satisfaisante pour un Russellien. Je vais conclure que le PR devrait s’écarter plus radicalement du NR. (shrink)

Hanks has defended a novel account of what propositions are. His key argument against Soames' rival view is that predication is not neutral. According to Hanks, predication is essentially committal. I show that Hanks' argument for this conclusion raises problems for his own account of questions and orders.

ABSTRACT Act-based theories of content hold that propositions are identical to acts of predication that we perform in thought and talk. To undergo an occurrent thought with a particular content is just to perform the act of predication that individuates that content. But identifying the content of a thought with the performance of an act of predication makes it difficult to explain the intentionality of bouletic mental activity, like wanting and desiring. In this paper, I argue that this difficulty is (...) insurmountable: the contents of occurrent desires cannot be determined by acts of predication. (shrink)

In this paper, I argue against a dispositional account of the intentionality of belief states that has been endorsed by proponents of phenomenal intentionality. Specifically, I argue that the best characterization of a dispositional account of intentionality is one that takes beliefs to be dispositions to undergo occurrent judgments. I argue that there are cases where an agent believes that p, but fails to have a disposition to judge that p.

In this paper we take up the question of the explanatory significance of the notion of propositional content. Our first goal is to disentangle two types of approach: According to what we call inflationism, propositions should be taken seriously enough to expect explanatory payoffs from them. The alternative deflationary approach rejects this claim. Our second goal is to explore the inflationism vs. deflationism contrast in depth by focusing on the distinction between singular and general propositions. We argue that inflationism fails (...) and outline a variety of deflationism that offers the best prospects for explaining the singular/general divide. (shrink)

Investigation into the reality of time can be pursued within the ontological domain or it can also span human thought and natural language. I propose to approach time by correlating three domains of inquiry: metaphysical time, the human concept of time, and temporal reference in natural language, entertaining the possibility of what I call a ‘horizontal reduction’ and ‘vertical reduction’. I present a view of temporalityL/E as epistemic modality, drawing on evidence from the L domain and its correlates in the (...) E and M domains. On this view, the human concept of time is a complex, ‘molecular’ concept and can be broken down into primitive concepts that are modal in nature, featuring as degrees of epistemic commitment to representations of states of affairs. I present evidence from tensed and tenseless languages and point out its compatibility with the view of real time as metaphysical modality. (shrink)

In this paper, I will counter Hodgson’s critique of Hanks’ assertion that neutral predication is incoherent, which is premised on the belief that asking is a neutral act. My defense of Hanks will be two-pronged. Firstly, I will provide textual proof that Hanks is, or should be, of the opinion that asking is not neutral, but rather a committal act. Secondly, I will illustrate how Hanks’ model can accommodate the committal aspect of asking.

In this paper, I defend a tripartite metaphysics of intentional mental states, according to which mental states are divided into subject, content, and attitude, against recent attempts at eliminating the attitude component (e.g., Montague, Oxford studies in philosophy of mind, 2022, 2, Oxford University Press). I suggest that a metaphysics composed of only subject and content cannot account for (a) multisensory perceptual experiences and (b) phenomenological differences between episodes of perception and imagination. Finally, I suggest that some of the motivations (...) behind the rejection of the attitude component can be accommodated within the tripartite framework. (shrink)

Many philosophers believe in things, propositions, which are the things that we believe, assert etc., and which are the contents of sentences. The act-type theory of propositions is an attempt to say what propositions are, to explain how we stand in relations to them, and to explain why they are true or false. The core idea of the act-type theory is that propositions are types of acts of predication. The theory is developed in various ways to offer explanations of the (...) important properties of propositions. I present the core idea of the theory, and some developments of it. I discuss the relationship between the theory and the content–force distinction. I also present an important type of objection that has been raised to the explanations offered by the act-type theory.

According to act theories, propositions are structured cognitive act‐types. Act theories appear to make propositions inherently representational and truth‐evaluable, and to provide solutions to familiar problems with alternative theories, including Frege’s and Russell’s problems, and the third‐realm and unity problems. Act theories have critical problems of their own, though: acts as opposed to their objects are not truth evaluable, not structured in the right way, not expressed by sentences, and not the objects of propositional attitudes. I show how identifying propositions (...) with other cognitive event‐types, namely thoughts, has the perceived virtues of act theories without the defects. (shrink)

Theories of structured meanings are designed to generate fine-grained meanings, but they are also liable to overgenerate structures, thus drawing structural distinctions without a semantic difference. I recommend the proliferation of very fine-grained structures, so that we are able to draw any semantic distinctions we think we might need. But, in order to contain overgeneration, I argue we should insert some degree of individuation between logical equivalence and structural identity based on structural isomorphism. The idea amounts to forming an equivalence (...) class of different structures according to one or more formal criteria and designating a privileged element as a representative of all the elements, i.e., a first among equals. The proposed method helps us to a cluster of notions of co-hyperintensionality. As a test case, I consider a recent objection levelled against the act theory of structured propositions. I also respond to an objection against my methodology. (shrink)

Realists about fictional characters posit a certain theoretical role and a candidate to fill this role. I will delineate the role realists take fictional characters like Emma Woodhouse to fill, and I will argue that it is better filled by what I will call ‘characterisations’. In explaining what I mean by ‘characterisations’, I will show that the existence of these entities is comparatively uncontroversial. Realists should acknowledge their existence, but doing so, I will argue, obviates the need to acknowledge the (...) existence of Emma and other fictional individuals. (shrink)

Ha sido uno de los alegatos centrales de la teoría así llamada “cognitiva” de las proposiciones que su carácter representacional —y, con ello, sus condiciones de verdad— es derivativo del carácter representacional primitivo de los actos cognitivos concretos por los que un agente predica una propiedad de un objeto. Las proposiciones heredan su carácter representacional porque son ‘tipos’ de actos cognitivos particulares que poseen el ‘mismo’ contenido representacional. Se argumenta en este trabajo que esta suposición está en conflicto con el (...) hecho de que actos cognitivos concretos son instancias de ciertos tipos. Bajo la mayoría de las concepciones acerca de lo que funda el hecho de que una pluralidad de objetos comparte la ‘misma’ naturaleza —i. e., acerca de cómo son algo ‘uno’ en lo múltiple— el carácter cualitativo de un objeto está fundado en universales o en alguna otra construcción aceptable para el nominalista.

This thesis addresses three challenges posed by intentionality - the ability of our mental states and language to be about something - to a logician: an apparent reference to non-existent objects, intentional indeterminacy and the failure of substitutivity of coextensive terms in an intentional context. Since intentionality plays an important role in our everyday reasoning, a proper formal account of it is highly desirable, yet it requires a departure from classical logic. One can modify classical logic and adapt the formal (...) apparatus to account for the aforementioned problems (Graham Priest’s logic for intentionality serves as an example of such an approach in this work) or one can make an even more radical shift and seek for inspiration in a different logical tradition like the terminist logic developed in the Late Middle Ages by figures like William of Ockham or John Buridan. The second path is explored here as a modest attempt to show that once we abandon the bias against the history of logic as irrelevant, we can actually get access to firm logical solutions inaccessible from a classical perspective, while still practising logic proper.
