In November 2022, OpenAI released ChatGPT, an incredibly sophisticated chatbot. Its capability is astonishing: as well as conversing with human interlocutors, it can answer questions about history, explain almost anything you might think to ask it, and write poetry. This level of achievement has provoked interest in questions about whether a chatbot might have something similar to human intelligence or even consciousness. Given that the function of a chatbot is to process linguistic input and produce linguistic output, we consider the (...) question whether a sophisticated chatbot might have inner speech. That is: Might it talk to itself, internally? We explored this via a conversation with ‘Playground’, a chatbot which is very similar to ChatGPT but more flexible in certain respects. We asked it questions which, plausibly, can only be answered if one first produces some inner speech. Here, we present our findings and discuss their philosophical significance. (shrink)

This paper aims to establish several interconnected points. First, a particular interpretation of the mathematical definition of information, known as the causal interpretation, is supported largely by misunderstandings of the engineering context from which it was taken. A better interpretation, which makes the definition and quantification of information relative to the function of its user, is outlined. The first half of the paper is given over to introducing communication theory and its competing interpretations. The second half explores three consequences of (...) the main thesis. First, a popular claim that the quantification of information in a signal is irrelevant for the meaning of that signal is exposed as fallacious. Second, a popular distinction between causal and semantic information is shown to be misleading, and I argue it should be replaced with a related distinction between natural and intentional signs. Finally, I argue that recent empirical work from microbiology and cognitive science drawing on resources of mathematical communication theory is best interpreted by the functional account. Overall, a functional approach is shown to be both theoretically and empirically well-supported. (shrink)

The free energy principle is notoriously difficult to understand. In this paper, we relate the principle to a framework that philosophers of biology are familiar with: Ruth Millikan’s teleosemantics. We argue that: systems that minimise free energy are systems with a proper function; and Karl Friston’s notion of implicit modelling can be understood in terms of Millikan’s notion of mapping relations. Our analysis reveals some surprising formal similarities between the two frameworks, and suggests interesting lines of future research. We hope (...) this will aid further philosophical evaluation of the free energy principle. (shrink)

Hutto and Myin claim that teleosemantics cannot account for mental content. In their view, teleosemantics accounts for a poorer kind of relation between cognitive states and the world but lacks the theoretical tools to account for a richer kind. We show that their objection imposes two criteria on theories of content: a truth-evaluable criterion and an intensionality criterion. For the objection to go through, teleosemantics must be subject to both these criteria and must fail to satisfy them. We argue that (...) teleosemantics meets the truth-evaluable criterion and is not required to meet the intensionality criterion. We conclude that Hutto and Myin’s objection fails. (shrink)

Over the last fifteen years, an ambitious explanatory framework has been proposed to unify explanations across biology and cognitive science. Active inference, whose most famous tenet is the free energy principle, has inspired excitement and confusion in equal measure. Here, we lay the ground for proper critical analysis of active inference, in three ways. First, we give simplified versions of its core mathematical models. Second, we outline the historical development of active inference and its relationship to other theoretical approaches. Third, (...) we describe three different kinds of claim -- labelled mathematical, empirical and general -- routinely made by proponents of the framework, and suggest dialectical links between them. Overall, we aim to increase philosophical understanding of active inference so that it may be more readily evaluated. -/- This the final submitted version of the Introduction to the Topical Collection "The Free Energy Principle: From Biology to Cognition", forthcoming in Biology & Philosophy.

Prominent views about representation share a premise: that mathematical communication theory is blind to representational content. Here I challenge that premise by rejecting two common misconceptions: that Claude Shannon said that the meanings of signals are irrelevant for communication theory (he didn't and they aren't), and that since correlational measures can't distinguish representations from natural signs, communication theory can't distinguish them either (the premise is true but the conclusion is false; no valid argument can link them).

This article establishes grounds on which attributions of information and encoding in animal signals are warranted. As common interest increases between evolutionary agents, the theoretical approach best suited to describing their interaction shifts from evolutionary game theory to communication theory, which warrants informational language. The take-home positive message is that in cooperative settings, signals can appropriately be described as transmitting encoded information, regardless of the cognitive powers of signalers. The canonical example is the honeybee waggle dance, which is discussed extensively (...) in the second and third sections. The take-home negative message is that signals are not always a consequence of coadaptation. The communication theory approach is just one end of a continuum explored more thoroughly by evolutionary game theory. The fourth and fifth sections explore this wider framework, as well as overturning some widely held misconceptions about information theory. (shrink)

With the tertiary education mantra of creativity, critical thinking and innovation in mind, we consider the critical-creativity of error. Taking the university to model social orthography, or ‘correct writing’, according to the norms of disciplines, we consider the role of error in the classroom. Looked at another way, error questions the norms governing norms and the instability of disciplinary grounds. Beyond correction, error involves a mis-taking, or taking another way. Tracing the origin of error we are able to reconstruct the (...) social world in terms of which it is conceivable for a mistake of any kind to have been made. The university, we find, withholds worlds which are not new but are sources of creativity, and constitutes a pluriversity or poly-versity. (shrink)

Can hybridism about moral claims be made to work? I argue it can if we accept the conventional implicature approach developed in Barker (Analysis 2000). However, this kind of hybrid expressivism is only acceptable if we can make sense of conventional implicature, the kind of meaning carried by operators like ‘even’, ‘but’, etc. Conventional implictures are a form of pragmatic presupposition, which involves an unsaid mode of delivery of content. I argue that we can make sense of conventional implicatures, (...) but doing so requires we embrace a form of pure, non-hybrid expressivism. This is a cognitivist expressivism I have developed elsewhere. We need cognitivist expressivism to make sense of how we evaluate—judge as correct or incorrect—implicature-bearing sentences. Once we embraced the possibility of this pure expressivism, we might as well be pure expressivists about normative discourse too. I show how we can do that. The motivations for a specifically hybrid theory are dialectically undercut. (shrink)

Combining a Nietzschean framework with close attention to a wide range of carefully selected literary texts, Autoaesthetics presents a case for Nietzche's centrality in contemporary aesthetic and literary studies. Based on Nietzche's own practice of combining poetry and philosophy by transcending ressentiment and approaching life to its fullest, Autoaesthetics engages in a heated but intricate debate through and with Nietzche's re-articulation of the self as a strategic (and impossible) aesthetic creation." "Stephen Barker argues that all notions of self (...) are aesthetic, literary, strategic, and teleological, and must be seen not in the context of any essential self but as a complex series of self-articulations. He sets out a strategy of reading that combines Nietzschean "psychology" with subsequent theoretical investigations and shows how Nietzschean dialectics of the self are at work in all (self-defining) human experience in the (post)modern world. His book itself is a play of dialectics (again after Nietzche), designed for interdisciplinary scholars and graduate students interested in exploring the scope of literary and aesthetic theory and philosophy.

Are the sculpture and the mass of gold which permanently makes it up one object or two? In this article, we argue that the monist, who answers ‘one object’, cannot accommodate the asymmetry of material constitution. To say ‘the mass of gold materially constitutes the sculpture, whereas the sculpture does not materially constitute the mass of gold’, the monist must treat ‘materially constitutes’ as an Abelardian predicate, whose denotation is sensitive to the linguistic context in which it appears. We motivate (...) this approach in terms of modal analyses of material constitution, but argue that ultimately it fails. The monist must instead accept a deflationary, symmetrical use of ‘materially constitutes’. We argue that this is a serious cost for her approach. (shrink)

Negative facts get a bad press. One reason for this is that it is not clear what negative facts are. We provide a theory of negative facts on which they are no stranger than positive atomic facts. We show that none of the usual arguments hold water against this account. Negative facts exist in the usual sense of existence and conform to an acceptable Eleatic principle. Furthermore, there are good reasons to want them around, including their roles in causation, chance-making (...) and truth-making, and in constituting holes and edges. (shrink)

This paper argues that the new metaphysics of powers, also known as dispositional essentialism or causal structuralism, is an illusory metaphysics. I argue for this in the following way. I begin by distinguishing three fundamental ways of seeing how facts of physical modality — facts about physical necessitation and possibility, causation, disposition, and chance — are grounded in the world. The first way, call it the first degree, is that the actual world or all worlds, in their entirety, are the (...) source of physical modality. Humeanism is the best known such approach, but there are other less well-known approaches. The second way, the second degree, is that the source of physical modality lies in certain second-order facts, involving a relation between universals. Armstrong’s necessitarianism and other views are second-degree views. The third way, the third degree, holds that properties themselves are the source of physical modality. This is the powers view. I examine four ways of developing the third degree: relational constitution, graph-theoretic structuralism, dispositional roles, and powerful qualities. All these ways are either incoherent, or just disguised versions of the first-degree. The new metaphysics of powers is illusory. With the collapse of the third degree, the second degree, the necessitarian view of law, collapses as well. I end the paper with some reflections on the first degree, on the problem of explaining necessary connections between distinct existences, and on the dim prospects of holist ontology. (shrink)

Bird argues that Armstrong’s necessitarian conception of physical modality and laws of nature generates a vicious regress with respect to necessitation. We show that precisely the same regress afflicts Bird’s dispositional-monist theory, and indeed, related views, such as that of Mumford & Anjum. We argue that dispositional monism is basically Armstrongian necessitarianism modified to allow for a thesis about property identity.

In this paper we present a new metaphysical theory of material objects. On our theory, objects are bundles of property instances, where those properties give the nature or essence of that object. We call the theory essential bundle theory. Property possession is not analysed as bundle-membership, as in traditional bundle theories, since accidental properties are not included in the object’s bundle. We have a different story to tell about accidental property possession. This move reaps many benefits. Essential bundle theory delivers (...) a simple theory of the essential properties of material objects; an explanation of how object coincidence can arise; an actual-world ground for modal differences between coincident objects; a simple story about intrinsic properties; and a plausible account of certain ubiquitous cases of causal overdetermination.

This book develops an alternative approach to sentence- and word-meaning, which I dub the speech-act theoretic approach, or STA. Instead of employing the syntactic and semantic forms of modern logic–principally, quantification theory–to construct semantic theories, STA employs speech-act structures. The structures it employs are those postulated by a novel theory of speech-acts. STA develops a compositional semantics in which surface grammar is integrated with semantic interpretation in a way not allowed by standard quantification-based theories. It provides a pragmatic theory of (...) truth, a treatment of logically complex discourse as expressive cognitive states, and a background metaphysics in which the world is a totality of logically simple states of affairs. The book also puts forward an account of how intentional states provide the simple, representational foundation for a superstructure of speech-act structures–a system of thoughts–that far outruns the expressive power of the intentional foundation. In short, it provides an account of cognitive foundations of a language and a naturalistic reduction of semantics through an expressive theory of semantic norms. (shrink)

Let us call dispositional monism the view that all natural properties have their identities fixed purely by their dispositional features, that is, by the patterns of stimulus and response in which they participate. DM implies that natural properties are pure powers: things whose natures are fully identified by their roles in determining the potentialities of events to cause or be caused. As pure powers, properties are meant to lack quiddities in Black's sense. A property possesses a quiddity just in case (...) its identity is fixed by something independent of the causal–nomological roles it may enter into. Paradigmatically, a categorical property is thought of as a property whose identity is fixed by a quiddity .The key question about the viability of DM as a theory of properties is how properties can be pure powers devoid of any quiddity. Bird provides an answer. According to Bird , ‘all there is to a property is a matter of second-order relations to other properties’. The second-order relation is just the relation that a disposition, its stimulus condition, and a manifestation condition bear to each other. Call this relation SR. SR is not causation or physical necessitation. The latter relations are first-order relations between concrete events. SR is a second-order relation. Its possession by properties explains why events featuring those properties can enter into certain first-order relations of causation or necessitation.Bird's thought then is this: the sense in which properties have their identities fixed purely by their causal–nomological roles is that they are relationally constituted, where the relation doing the constituting is SR. 1 This thesis of relational constitution does not imply that natural properties are themselves relations. Nothing prevents the identity …. (shrink)

Are all instances of the T-schema assertable? I argue that they are not. The reason is the presence of conventional implicature in a language. Conventional implicature is meant to be a component of the rule-based content that a sentence can have, but it makes no contribution to the sentence's truth-conditions. One might think that a conventional implicature is like a force operator. But it is not, since it can enter into the scope of logical operators. It follows that the semantic (...) content of a sentence is not given simply by its truth-conditional content. So not all instances of the T-schema are assertable in the relevant sense. Consequently, there is a strong case to be made against truth-conditional semantics of the disquotational variety and deflationism about truth. (shrink)

I offer a new theory of faultless disagreement, according to which truth is absolute (non-relative) but can still be non-objective. What's relative is truth-aptness: a sentence like ‘Vegemite is tasty’ (V) can be truth-accessible and bivalent in one context but not in another. Within a context in which V fails to be bivalent, we can affirm that there is no issue of truth or falsity about V, still disputants, affirming and denying V, were not at fault, since, in their context (...) of assertion V was bivalent. This theory requires a theory of assertion that is a form of cognitive expressivism. (shrink)

Frege’s distinction between force and sense is a central pillar of modern thinking about meaning. This is the idea that a self-standing utterance of a sentence S can be divided into two components. One is the proposition P that S’s linguistic meaning and context associates with it. The other is S’s illocutionary force. The force/sense distinction is associated with another thesis, the embedding principle, that implies that the only content that embeds in compound sentences is propositional content. We argue that (...) both the Force/Sense distinction and the principle of embedding are seriously challenged by figurative language, and irony in particular. We conclude that theorists need to go back to the drawing board about the nature of illocutionary acts. (shrink)

In this chapter I consider the prospects of globalizing expressivism. Expressivism is a position in the philosophy of language that questions the central role of representation in a theory of meaning or linguistic function. An expressivist about a domain D of discourse proposes that utterances of sentences in D should not be seen, at the level of analysis as representing how things are, but as expression of non-representational states. So, in the domain of value-utterances, the standard idea is that speakers (...) are expressing affective-states, such as approval or disapproval focused on objects or conditions. Global expressivism is the thesis that for all domains of discourse, we treat utterances, at the level of analysis, as expressing non-representational states. I set out several conceptions of how one might formulate this programme. The first involves minimalism about truth and semantic content – and only partially gives up representationalism (viz., the thesis that some utterances express representational states). The second is Price’s conception, which incorporates minimalism, Brandomian inferentalism, and concepts from Carnap, but still clings to representationalism. I then arrive at my favoured third conception, which does not employ minimalism or inferentialism, and eliminates vestiges of representationalism. It does the latter by embracing expressivism about meaning-attribution. Having set out key aspects of the approach I then address the question of metaphysics. What metaphysical conception of reality goes with global expressivism so understood? I argue it implies a form of metametaphysical nihilism. This is that idea that reality lacks any ultimate nature. (shrink)

There is a wide-spread belief amongst theorists of mind and language. This is that in order to understand the relation between language, thought, and reality we need a theory of meaning and content, that is, a normative, formal science of meaning, which is an extension and theoretical deepening of folk ideas about meaning. This book argues that this is false, offering an alternative idea: The form of a theory that illuminates the relation of language, thought, and reality is a theory (...) of language agency. In a nutshell, the theory of language agency is a theory of competence, without being a theory of understanding or grasping rules. It is a theory of cognitive structure and language production. This theory distils all there is to say about language, thought, and reality. It does not supplement a theory of truth-conditions or semantic norms. It is not the explanation of how a speaker, qua cognitive system causally embedded in a larger reality, is able to use a language with some pre-existing semantic characterization. There is no pre-existing semantic characterization. Nevertheless, there are facts of meaning, as good as any other facts. The dissolution of the theory of meaning is accompanied by another disappearance. That is the disappearance of metaphysical questions in a number of domains. Once we complete the theory of language agency, then just as theoretical questions about meaning disappear, certain theoretical questions about existence disappear. Having provided a theory of the language agency for talk of meaning, fact, property, relation, and proposition, there is no question left over about what meanings, facts, properties, relations, and propositions are. There is no theory to be given of their natures. This is not because they have primitive irreducible natures. Rather it is because, in a sense to be clarified in this work, they lack natures. I call this approach to language agency Global Expressivism. That is because it generalizes some of the insights brought to the study of value-language by expressivists. However, it removes these insights from the clouding affects of attempting to make expressivism a semantic theory. Expressivism about value fails as a semantic theory of value talk. However, global expressivism can succeed as a theory of all talk because it is not a semantic theory but a theory of language agency, wherein the theory of meaning is replaced by a theory of talk about meaning.

This paper falls into two parts. In the first part, I argue that consideration of general indicative conditionals, e.g., sentences like If a donkey brays it is beaten, provides a powerful argument that a pure material implication analysis of indicative if p, q is correct. In the second part I argue, opposing writers like Jackson, that a Gricean style theory of pragmatics can explain the manifest assertability conditions of if p, q in terms of its conventional content – assumed to (...) be merely (p⊃q) – and the conversational implicature contents which utterance of if p, q may gain in certain contexts. I also defend the pragmatic approach against a recent objection by Edgington that appeal to pragmatics cannot explain what we are inclined to say about the believability conditions, as opposed to the assertability conditions, of indicative if p, q.

My goal is to illuminate truth-making by way of illuminating the relation of making. My strategy is not to ask what making is, in the hope of a metaphysical theory about is nature. It's rather to look first to the language of making. The metaphor behind making refers to agency. It would be absurd to suggest that claims about making are claims about agency. It is not absurd, however, to propose that the concept of making somehow emerges from some feature (...) to do with agency. That's the contention to be explore in this paper. The way to do this is through expressivism,. Truth-making claims, and making-claims generfally, are claims in which we express mental states linked to our maipulation of concepts, like truth. In particular, they express disposition to undertake derivations using inference rules, in which introduction rules have a specific role. I then show how this theory explains our intuitions about truth's asymmetric dependence on being. (shrink)

At the heart of semantics in the 20th century is Frege’s distinction between sense and force. This is the idea that the content of a self-standing utterance of a sentence S can be divided into two components. One part, the sense, is the proposition that S’s linguistic meaning and context associates with it as its semantic interpretation. The second component is S’s illocutionary force. Illocutionary forces correspond to the three basic kinds of sentential speech acts: assertions, orders, and questions. Forces (...) are then kinds of acts in which propositions are deployed with certain purposes. I sketch a speech-act theoretic semantics in which that distinction does not hold. Instead of propositions and forces, the theory proposes proto-illocutionary acts and illocutionary acts. The orthodox notion of a proposition plays no role in the framework, which is a good thing, since that notion is deeply problematic. The framework also shows how expressionists, who embrace a sophisticated speech-act framework, face no Frege-Geach embedding problem, since the latter assumes the Sense/Force distinction. (shrink)
