Inferentialist Accounts of Meaning and Content

The paper begins with a conceptual discussion of Michael Dummett's proof-theoretic justification of deduction or proof-theoretic semantics, which is based on what we might call Gentzen's thesis: 'the introductions constitute, so to speak, the "definitions" of the symbols concerned, and the eliminations are in the end only consequences thereof, which could be expressed thus: In the elimination of a symbol, the formula in question, whose outer symbol it concerns, may only "be used as that which it means on the basis (...) of the introduction of this symbol".' The intuitive philosophical content of Dummett's notions of harmony and stability is that harmony obtains if the grounds for asserting a proposition match the consequences of accepting it, and stability obtains if the converse also holds. Rules of inference define the meanings of a logical constant they govern if and only if they are stable. Gentzen observed that 'it should be possible to establish on the basis of certain requirements that the elimination rules are functions of the corresponding introduction rules.' One of the objectives of this paper is to specify such a function: I will specify a process by which it is possible to determine the elimination rules of logical constants from their introduction rules, and conversely, to determine the introduction rules from the elimination rules. I'll give the general forms of rules of inference and generalised reduction procedures for the normalisation of deduction. I'll give a formally precise characterisations of harmony and stability and show that deductions in logics that contain only constants governed by stable rules always normalise. (shrink)

Boghossian (1996) has put forward an interesting explanation of how we can acquire logical knowledge via implicit definitions that makes use of a special template. Ebert (2005) has argued that the template is unserviceable, as it doesn't transmit warrant. In this paper, we defend the template. We first suggest that Jenkins (2008)’s response to Ebert fails because it focuses on doxastic rather than propositional warrant. We then reject Ebert’s objection by showing that it depends on an implausible and incoherent assumption.

This paper in revised form appears in Facta Philosophica 5:1 (2003) 49­75. It addresses some problems about intensional transitives raised by Moltmann and Zimmerman, corrects some oversights in my paper in The Proceedings of the Aristotelian Society (S.V. for 2002), and adds new material on binary vs. tripartite construals of “relational/notional”, bridge inferences, weakening inferences, and the relevance problem. Its other sections are, like the PASS paper, concerned with the conjunctive force of disjunctive NP complements of intensional transitive verbs: “Smith (...) needs a good lawyer or a friendly judge” on its normal reading implies both “a good lawyer could help him” AND “a friendly judge could help him”. The reading on which “Smith needs a good lawyer or a friendly judge” is implied just by “Smith needs a good lawyer” (and so doesn’t imply a friendly judge could help him) is much less preferred, except when the disjunction is followed by a coda such as “and he doesn’t care which”.

Huw Price has developed versions of naturalism and anti-representationalism to create a distinctive brand of pragmatism. ‘Subject naturalism’ focuses on what science says about human beings and the function of our linguistic practices, as opposed to orthodox contemporary naturalism’s privileging of the ontology of the natural sciences. Price’s anti-representationalism rejects the view that what makes utterances contentful is their representing reality. Together, they are to help us avoid metaphysical ‘placement problems’: how e.g. mind, meaning, and morality fit into the natural (...) world. By combining subject naturalism and his own ‘global’ version of expressivism with Robert Brandom’s inferentialism about content, Price proposes a pragmatist ‘anthropology’ as a replacement for substantively metaphysical approaches to placement problems. In this paper I argue that Price’s project cannot succeed, and that this shows something important about what form pragmatism ought to take. Price’s view doesn’t work because no subject naturalist vocabulary is sufficient to describe any assertional practice; there is no way to connect his expressive-functionalist explanations to the practices and concepts which are their subject – nor, even, to the human subjects who are the focus of a philosophical anthropology. I close by suggesting how we might improve on these shortcomings of Price’s pragmatism. (shrink)

Within contemporary philosophy of mind, it is taken for granted that externalist accounts of meaning and mental content are, in principle, orthogonal to the matter of whether cognition itself is bound within the biological brain or whether it can constitutively include parts of the world. Accordingly, Clark and Chalmers (1998) distinguish these varieties of externalism as ‘passive’ and ‘active’ respectively. The aim here is to suggest that we should resist the received way of thinking about these dividing lines. With reference (...) to Brandom’s (1994; 2000; 2008) broad semantic inferentialism, we show that a theory of meaning can be at the same time a variety of active externalism. While we grant that supporters of other varieties of content externalism (e.g., Putnam 1975 and Burge 1986) can deny active externalism, this is not an option for semantic inferentialists: On this latter view, the role of the environment (both in its social and natural form) is not ‘passive’ in the sense assumed by the alternative approaches to content externalism.

We develop a novel solution to the negation version of the Frege-Geach problem by taking up recent insights from the bilateral programme in logic. Bilateralists derive the meaning of negation from a primitive *B-type* inconsistency involving the attitudes of assent and dissent. Some may demand an explanation of this inconsistency in simpler terms, but we argue that bilateralism’s assumptions are no less explanatory than those of *A-type* semantics that only require a single primitive attitude, but must stipulate inconsistency elsewhere. Based (...) on these insights, we develop a version of B-type expressivism called *inferential expressivism*. This is a novel semantic framework that characterises meanings by inferential roles that define which *attitudes* one can *infer* from the use of terms. We apply this framework to normative vocabulary, thereby solving the Frege-Geach problem generally and comprehensively. Our account moreover includes a semantics for epistemic modals, thereby also explaining normative terms under epistemic modals. (shrink)

In this paper I present how the normative inferentialist can make the distinction between sentence meaning and content of the utterance. The inferentialist can understand sentence meaning as a role conferred to that sentence by the rules governing inferential transitions and content of the utterance as just a part of sentence meaning. I attempt to show how such a framework can account for prominent scenarios presented by contextualists as a challenge to semantic minimalism/literalism. I argue that inferentialism can address contextualist (...) challenges in a simple and effective manner by understanding sentence meaning as broad, but invariant. (shrink)

_ Source: _Page Count 26 The dilemma of presentism is sometimes represented as a choice between the increased relevance and utility of a historiographic practice that can articulate its relation to the present and the increased objectivity or openness to the otherness of the past of a historiographic practice that articulates the past “on its own terms.” The present article argues that, at least with reference to intellectual history, we should understand that ideas appear most fully when they are run (...) through a multitude of contexts and not rooted exclusively in circumstances contemporaneous to _either_ the original emergence of an idea _or_ the writer and first reader of the historical account. The following thesis is advanced: ideas appear only over time, and the contextualization, decontextualization, and recontextualization of ideas in different places and times are all essential to such intellectual historical “appearance.” The article then articulates its position more precisely by means of Robert Brandom’s inferentialism. And, finally, this line of inquiry is exemplified and interrogated by means of a concrete historiographic case—namely, a political theoretical investigation of the intellectual legacy of the Weimar Republic.

Inferentialism is a theory in the philosophy of language which claims that the meanings of expressions are constituted by inferential roles or relations. Instead of a traditional model-theoretic semantics, it naturally lends itself to a proof-theoretic semantics, where meaning is understood in terms of inference rules with a proof system. Most work in proof-theoretic semantics has focused on logical constants, with comparatively little work on the semantics of non-logical vocabulary. Drawing on Robert Brandom’s notion of material inference and Greg Restall’s (...) bilateralist interpretation of the multiple conclusion sequent calculus, I present a proof-theoretic semantics for atomic sentences and their constituent names and predicates. The resulting system has several interesting features: (1) the rules are harmonious and stable; (2) the rules create a structure analogous to familiar model-theoretic semantics; and (3) the semantics is compositional, in that the rules for atomic sentences are determined by those for their constituent names and predicates. (shrink)

We explore the problems that confront any attempt to explain or explicate exactly what a primitive logical rule of inference is, or consists in. We arrive at a proposed solution that places a surprisingly heavy load on the prospect of being able to understand and deal with specifications of rules that are essentially self-referring. That is, any rule $\rho $ is to be understood via a specification that involves, embedded within it, reference to rule $\rho $ itself. Just how we (...) arrive at this position is explained by reference to familiar rules as well as less familiar ones with unusual features. An inquiry of this kind is surprisingly absent from the foundations of inferentialism—the view that meanings of expressions are to be characterized by the rules of inference that govern them. (shrink)

In this paper, I develop a metasemantics for relaxed moral realism. More precisely, I argue that relaxed realists should be inferentialists about meaning and explain that the role of evaluative moral vocabulary is to organise and structure language exit transitions, much as the role of theoretical vocabulary is to organise and structure language entry transitions.

Although there is a prima facie strong case for a close connection between the meaning and inferential role of certain expressions, this connection seems seriously threatened by the semantic and logical paradoxes which rely on these inferential roles. Some philosophers have drawn radical conclusions from the paradoxes for the theory of meaning in general, and for which sentences in our language are true. I criticize these overreactions, and instead propose to distinguish two conceptions of inferential role. This distinction is closely (...) tied to two conceptions of deductive logic, and it is the key, I argue, for understanding first the connection between meaning and inferential role, and second what the paradoxes show more generally.

This edited volume examines the relationship between collective intentionality and inferential theories of meaning. The book consists of three main sections. The first part contains essays demonstrating how researchers working on inferentialism and collective intentionality can learn from one another. The essays in the second part examine the dimensions along which philosophical and empirical research on human reasoning and collective intentionality can benefit from more cross-pollination. The final part consists of essays that offer a closer examination of themes from inferentialism (...) and collective intentionality that arise in the work of Wilfrid Sellars. Groups, Norms, and Practices provides a template for continuing an interdisciplinary program in philosophy and the sciences that aims to deepen our understanding of human rationality, language use, and sociality.

What is the relationship between the world and logic, between intuition and language, between objects and their quantitative determinations? Rationalists, on the one hand, hold that the world is structured in a rational way. Representationalists, on the other hand, assume that language, logic, and mathematics are only the means to order and describe the intuitively given world. In World and Logic, Jens Lemanski takes up three surprising arguments from Arthur Schopenhauer’s hitherto undiscovered Berlin Lectures, which concern the philosophy of language, (...) logic, and mathematics. Based on these arguments, Lemanski develops a new position entitled ‘rational representationalism’: the world is always structured by human beings according to linguistic, logical, and mathematical principles, but the basic vocabulary of these structural descriptions already contains metaphors taken from the world around us.

In his 1975 paper “The Meaning of ‘Meaning’”, Hilary Putnam famously argued for semantic externalism. Little attention has been paid, however, to the fact that already in 1973, Putnam had presented the idea of the linguistic division of labor and the Twin Earth thought experiment in his comment on Wilfrid Sellars’s “Meaning as Functional Classification” at a conference, and Sellars had replied to Putnam from a broadly inferentialist perspective. The first half of this paper aims to trace the development of (...) Putnam’s semantic externalism, situate his debate with Sellars in it, and reconstruct the two arguments he presented against Sellars. The second half of this paper aims to reconstruct how Sellars replied to Putnam. I argue that Sellars not only accepts the social character of language but also suggests how inferentialists can accommodate the contribution of the world. Sellars’s key idea is that substance terms have a “promissory note aspect” which is to be cashed out in a successor conceptual framework. I reconstruct Sellars’s position as ideal successor externalism, and compare it with temporal externalism. (shrink)

It’s commonly thought that, in conversation, speakers accept and reject propositions that have been asserted by others. Do speakers accept and reject questions as well? Intuitively, it seems that they do. But what does it mean to accept or reject a question? What is the relationship between these acts and those of asking and answering questions? Are there clear and distinct classes of reasons that speakers have for acceptance and rejection of questions? This chapter seeks to address these issues. Beyond (...) their intrinsic interest to those working on the nature of questions, solutions to these problems may aid the extension of inferentialist approaches to logic and language. Inferentialists who think that inferences should be conceived in terms of the norms we are subject to in virtue of both the sentences we accept or assert as well as those we reject or deny are known as bilateralists. A coherent account of accepting and rejecting questions raises the prospects for a bilateralism that interprets question-involving or erotetic inferences according to these additional primitives. While a full-blown bilateralism for erotetic inferences and ultimately for question-forming operators themselves far exceeds this chapter’s scope, the work presented here does sketch the first steps in that direction.

On a widespread naturalist view, the meanings of mathematical terms are determined, and can only be determined, by the way we use mathematical language—in particular, by the basic mathematical principles we’re disposed to accept. But it’s mysterious how this can be so, since, as is well known, minimally strong first-order theories are non-categorical and so are compatible with countless non-isomorphic interpretations. As for second-order theories: though they typically enjoy categoricity results—for instance, Dedekind’s categoricity theorem for second-order PA and Zermelo’s quasi-categoricity (...) theorem for second-order ZFC—these results require full second-order logic. So appealing to these results seems only to push the problem back, since the principles of second-order logic are themselves non-categorical: those principles are compatible with restricted interpretations of the second-order quantifiers on which Dedekind’s and Zermelo’s results are no longer available. In this paper, we provide a naturalist-friendly, non-revisionary solution to an analogous but seemingly more basic problem—Carnap’s Categoricity Problem for propositional and first-order logic—and show that our solution generalizes, giving us full second-order logic and thereby securing the categoricity or quasi-categoricity of second-order mathematical theories. Briefly, the first-order quantifiers have their intended interpretation, we claim, because we’re disposed to follow the quantifier rules in an open-ended way. As we show, given this open-endedness, the interpretation of the quantifiers must be permutation-invariant and so, by a theorem recently proved by Bonnay and Westerståhl, must be the standard interpretation. Analogously for the second-order case: we prove, by generalizing Bonnay and Westerståhl’s theorem, that the permutation invariance of the interpretation of the second-order quantifiers, guaranteed once again by the open-endedness of our inferential dispositions, suffices to yield full second-order logic.

This paper provides a proof-theoretic account of imperative logical consequence by generalising Greg Restall’s multiple conclusion bilateralism for declarative logic. According to imperative bilateralism, a sequent Γ ⊢ Δ is valid iff jointly commanding all the imperatives Φ ∈ Γ and prohibiting all the imperatives Ψ ∈ Δ clashes. This account has three main virtues: (1) it provides a proof-theoretic account of imperatives; (2) it does not rely on the controversial notion of imperative inference; and (3) it is neutral regarding (...) cognitivism about imperatives.

Semantic dispositionalism is roughly the view that meaning a certain thing by a word, or possessing a certain concept, consists in being disposed to do something, e.g., infer a certain way. Its main problem is that it seems to have so many and disparate exceptions. People can fail to infer as required due to lack of logical acumen, intoxication, confusion, deviant theories, neural malfunctioning, and so on. I present a theory stating possession conditions of concepts that are counterfactuals, rather than (...) disposition attributions, but which is otherwise similar to inferentialist versions of dispositionalism. I argue that it can handle all the exceptions discussed in the literature without recourse to ceteris paribus clauses. Psychological exceptions are handled by suitably undemanding requirements (unlike that of giving the sum of any two numbers) and by setting the following two preconditions upon someone’s making the inference: that she considers the inference and has no motivating reason against it. The non-psychological exceptions, i.e., cases of neural malfunctioning, are handled by requiring that the counterfactuals be true sufficiently often during the relevant interval. I argue that this accommodates some important intuitions about concept possession, in particular, the intuition that concept possession is vague along a certain dimension. (shrink)

In “Psychopower and Ordinary Madness” my ambition, as it relates to Bernard Stiegler’s recent literature, was twofold: 1) critiquing Stiegler’s work on exosomatization and artefactual posthumanism—or, more specifically, nonhumanism—to problematize approaches to media archaeology that rely upon technical exteriorization; 2) challenging how Stiegler engages with Giuseppe Longo and Francis Bailly’s conception of negative entropy. These efforts were directed by a prevalent techno-cultural qualifier: the rise of Synthetic Intelligence (including neural nets, deep learning, predictive processing and Bayesian models of cognition). This (...) paper continues this project but first directs a critical analytic lens at the Derridean practice of the ontologization of grammatization from which Stiegler emerges while also distinguishing how metalanguages operate in relation to object-oriented environmental interaction by way of inferentialism. Stalking continental (Kapp, Simondon, Leroi-Gourhan, etc.) and analytic traditions (e.g., Carnap, Chalmers, Clark, Sutton, Novaes, etc.), we move from artefacts to AI and Predictive Processing so as to link theories related to technicity with philosophy of mind. Simultaneously drawing forth Robert Brandom’s conceptualization of the roles that commitments play in retrospectively reconstructing the social experiences that lead to our endorsement(s) of norms, we compliment this account with Reza Negarestani’s deprivatized account of intelligence while analyzing the equipollent role between language and media (both digital and analog).

For semantic inferentialists, the basic semantic concept is validity. An inferentialist theory of meaning should offer an account of the meaning of "valid." If one tries to add a validity predicate to one's object language, however, one runs into problems like the v-Curry paradox. In previous work, I presented a validity predicate for a non-transitive logic that can adequately capture its own meta-inferences. Unfortunately, in that system, one cannot show of any inference that it is invalid. Here I extend the (...) system so that it can capture invalidities. (shrink)

We present epistemic multilateral logic, a general logical framework for reasoning involving epistemic modality. Standard bilateral systems use propositional formulae marked with signs for assertion and rejection. Epistemic multilateral logic extends standard bilateral systems with a sign for the speech act of weak assertion (Incurvati and Schlöder 2019) and an operator for epistemic modality. We prove that epistemic multilateral logic is sound and complete with respect to the modal logic S5 modulo an appropriate translation. The logical framework developed provides the (...) basis for a novel, proof-theoretic approach to the study of epistemic modality. To demonstrate the fruitfulness of the approach, we show how the framework allows us to reconcile classical logic with the contradictoriness of so-called Yalcin sentences and to distinguish between various inference patterns on the basis of the epistemic properties they preserve.

Destutt de Tracy zielt darauf ab, zu erklären, wie inter- und transsubjektive Prozesse auf das einzelne Individuum wirken und es gestalten. Dafür braucht er eine externalistische Sprachtheorie und eine sensualistische kognitive Architektur, nach der Denken Empfinden ist. Das Denken ist relational, aber wird nicht auf kognitiver Ebene durch sprachähnliche Strukturen – durch die Syntax und Semantik einer Mentalsprache – implementiert. Obwohl Externalismus und sensualistische Architektur in eine inkohärente Theorie zu münden scheinen, versucht Destutt de Tracy die Spannung durch seine Entwicklungsgeschichte (...) zu lösen, nach der Systematizität als assoziativ und symbolisch, aber nicht als sprachlich analysiert wird.

In this paper I aim to defend a twofold thesis. On one hand, I will sup-port, against Perini [7], the indispensability of diagrams when structurally complex biomolecules are concerned, since it is not possible to satisfactorily use linguistic-sentential representations at that domain. On the other hand, even when diagrams are dispensable I will defend than they will generally be more effective than other representations in encoding biomolecular knowledge, relying on Kulvicki-Shimojima’s diagrammatic effectiveness thesis. Finally, I will ground many epistemic virtues (...) of biomolecular diagrams (understandability, explanatory power, prediction and hypothesis evaluation) on their cognitive-computational indispensability and their semantic-epistemic effectiveness.

We present an inferentialist account of the epistemic modal operator might. Our starting point is the bilateralist programme. A bilateralist explains the operator not in terms of the speech act of rejection ; we explain the operator might in terms of weak assertion, a speech act whose existence we argue for on the basis of linguistic evidence. We show that our account of might provides a solution to certain well-known puzzles about the semantics of modal vocabulary whilst retaining classical logic. (...) This demonstrates that an inferentialist approach to meaning can be successfully extended beyond the core logical constants. (shrink)

While there has been significant philosophical debate on whether nonlinguistic animals can possess conceptual capabilities, less time has been devoted to considering 'talking' animals, such as parrots. When they are discussed, their capabilities are often downplayed as mere mimicry. The most explicit philosophical example of this can be seen in Brandom's frequent comparisons of parrots and thermostats. Brandom argues that because parrots (like thermostats) cannot grasp the implicit inferential connections between concepts, their vocal articulations do not actually have any conceptual (...) content. In contrast, I argue that Pepperberg's work with Alex (and other African grey parrots) provides evidence that the vocal articulations of at least some parrots have conceptual content. Using Frege's insight that numbers assert something about a concept, I argue that Alex's ability to answer the question "How many?" depended upon a prior grasp of conceptual content. Developing this claim, I argue that Alex's arithmetical abilities show that he was capable of using numbers as both concepts and objects. Frege's theoretical insight and Pepperberg's empirical work provide reason to reconsider the capabilities of parrots, as well as what sorts of tasks provide evidence for conceptual content. (shrink)

The dissertation provides an analysis and elaboration of Michael Dummett's proof-theoretic notions of validity. Dummett's notions of validity are contrasted with standard proof-theoretic notions and formally evaluated with respect to their adequacy to propositional intuitionistic logic.

A semantic theory is committed to semantic monism just in case every particular semantic property posited by the theory is a member of the same kind. The commitment to semantic monism appears to draw some support from the need to provide a compositional semantics, since taking a single kind of semantic property as key to a semantic theory affords a uniform pattern on the basis of which the meaning of any given sentence can be compositionally determined. This line of support (...) highlights a tension between the principle of compositionality and taking a more pluralistic approach to semantic theorizing. In this essay, that tension is relieved, leaving open the prospect of a pluralistic semantic theory that observes the principle of compositionality. (shrink)

This paper argues that we need to re-think the semantics/pragmatics distinction in the light of new evidence from embedding of irony. This raises a new version of the old problem of ‘embedded implicatures’. I argue that embedded irony isn’t fully explained by solutions proposed for other embedded implicatures. I first consider two strategies: weak pragmatics and strong pragmatics. These explain embedded irony as truth-conditional content. However, by trying to shoehorn irony into said-content, they raise problems of their own. I conclude (...) by considering how a modified Gricean model can explain that irony embeds qua implicature. This leads us to prefer a local implicature model. This has important consequences for how we draw the semantics/pragmatics distinction. (shrink)

Wittgenstein’s Investigations proposed an egalitarian view about language games, emphasizing their plurality (“language has no downtown”). Uses of words depend on the game one is playing, and may change when playing another. Furthermore, there is no privileged game dictating the rules for the others: games are as many as purposes. This view is pluralist and egalitarian, but it says little about the connection between meaning and use, and about how a set of rules is responsible for them in practice. Brandom’s (...) Making It Explicit attempted a straightforward answer to these questions, by developing Wittgensteinian insights: the primacy of social practice over meanings; the idea that meaning is use; the idea of rule–following to understand participation in social practices. Nonetheless, Brandom defended a non–Wittgensteinian conception of discursive practice: language has a “downtown”, the game of “giving and asking for reasons”. This is the idea of a normative structure of language, consisting of advancing claims and drawing inferences. By means of assertions, speakers undertake “commitments” that can be challenged/defended in terms of reasons (those successfully justified can gain “entitlement”). This game is not one among many: it is indispensable to the very idea of discursive practice. In this paper, my aim will be that of exploring the main motivations and implications of both perspectives. (shrink)

I present a sequent calculus that extends a nonmonotonic reflexive consequence relation as defined over an atomic first-order language without variables to one defined over a logically complex first-order language. The extension preserves reflexivity, is conservative (therefore nonmonotonic) and supraintuitionistic, and is conducted in a way that lets us codify, within the logically extended object language, important features of the base thus extended. In other words, the logical operators in this calculus play what Brandom (2008) calls expressive roles. Expressivist logical (...) systems have already been proposed for propositional logics (see Hlobil, 2016, and Kaplan, 2018) but not for first-order logics. An advantage of this calculus over standard first-order calculi (e.g., those in Gentzen, 1935/1964) is that universally quantified variables behave as they should even in the presence of arbitrary nonlogical axioms. I claim that because of this robust well-behavedness of variables, this calculus also provides logical inferentialists with a way to understand the meanings of variables in terms of the roles those variables play in a wide range of inferences that is not limited to purely logical ones (e.g, mathematical inferences).

Much thought has been devoted to how metaethical disagreement between moral realism and expressivism can be saved once minimalism starts creeping. Very little thought has been given to how creeping minimalism affects error-theories’ disagreement with their metaethical competitors. The reason for this omission, I suspect, is found in the belief that whilst locating distinctive moral realist and expressivist positions within a minimalist landscape poses a severe challenge, no such difficulties are encountered when differentiating error-theories from moral realism and expressivism. In (...) the first part of this paper, I show that this belief is mistaken: Insofar as moral realists and error-theorists are still taken to disagree, creeping minimalism renders their disagreement moral, but makes these positions metaethically indistinguishable. In the second part of the paper, I present a modified inferentialist solution to the problem of creeping minimalism which seeks to put error-theories back on the metaethical map. Yet, this too comes at a cost, in that it significantly modifies our interpretation of error-theories. Whichever way we turn, then, creeping minimalism not only forces us to re-phrase metaethical positions in a way that is compatible with minimalism, but also requires us to change our very understanding of these positions.

One of the most striking clashes between the results of Ludwig Wittgenstein’s reflections on language games and Robert Brandom’s normative analysis of pragmatics concerns the pride of place granted by the latter to assertional practices. While Wittgenstein believes that there is no privileged language game, Brandom maintains that the game of giving and asking for reasons is fundamental for the possibility of any linguistic practice to be properly meaningful. Recently, Rebecca Kukla and Mark Lance proposed to generalize Brandom’s normative pragmatics (...) in order to provide a more fine–grained analysis of the normativity that governs discursive practices. It is a courageous enterprise that challenges the predominance of the cognitive approach in pragmatics by underpinning a different way to understand the notion of meaning. Their proposal, however, requires to take into account many different sorts of speech acts on a par and, by doing so, it is in tension with Brandom’s approach. This paper explores the shape of this tension in order to see whether or not a unitary characterization of rationality can be envisaged in Wittgenstein’s and Brandom’s way of accounting for the ability to deploy conceptual contents in linguistic practices.

The aim of this paper is to characterize the semantic notion of trust, as it has been introduced by Robert Brandom. Traditionally, the concept of trust does not play any central role in semantics. This, I suggest, depends on the fact that the very social dimension plays a rather marginal role in the traditional representationalist theory of meaning. In Brandom’s normative inferentialism, instead, trust is essential to the constitution of the discursive communities, whose rules are taken to define contents.

In this dissertation, I aim to develop and defend a novel, pragmatist approach to foundational questions about meaning, especially the meaning of deontic moral vocabulary. Drawing from expressivists and inferentialists, I argue that meaning is best explained by the various kinds of norms that govern the use of a vocabulary. Along with inferential norms, I argue we must extend our account to discursive norms that govern normative statuses required to felicitously utter certain speech-acts—norms of authority—and the transitions in normative statuses (...) affected by speech-acts—pragmatic norms. These structural discursive norms differentiate discursive practices and account for distinctive features such as objectivity and motivational import that some have and others lack. The structure exhibited by a practice is then explained in terms of its utility, making it possible to see how different discursive practices are answerable to the different needs and purposes of the discursive beings who use them. I call the resulting explanatory framework a pragmatic analysis of linguistic meaning (PALM). -/- Turning my attention to moral “ought,” I argue that the structural discursive norms of moral discourse differentiate it from other objective discourses, like empirical discourse, on the one hand, and from other normative discourses, like prudential discourse, on the other. Drawing on work in evolutionary psychology and anthropology, I complete the PALM with an account of moral discourse a meta-normative practice with a metacoordinative function. Its utility for the discursive beings who use it lies in its enabling them to remedy certain tensions and instabilities that arise in their other coordinative, normative practices in a way that minimizes the risk of domination by alpha-type freeriders, the fracturing of social groups, and individual defection from cooperative endeavors. -/- In the final two chapters, I leverage the account to defend a pragmatist-friendly notion of objectivity in terms of a structure of distributed epistemic authority according to which no claim within a practice is ultimately authoritative or immune from challenge and to reconcile this sense of objectivity with a persistent pressure toward a kind of relativism that restricts the standing to make moral claims to members of the relevant communities.

Expressivism in logic is the view that logical vocabulary plays a primarily expressive role: that is, that logical vocabulary makes perspicuous in the object language structural features of inference and incompatibility (Brandom, 1994, 2008). I present a precise, technical criterion of expressivity for a logic (§2). I next present a logic that meets that criterion (§3). I further explore some interesting features of that logic: first, a representation theorem for capturing other logics (§3.1), and next some novel logical vocabulary for (...) expressing structural features of inference (§4).

According to Brandom’s conceptual role semantics, to grasp a concept involves a commitment to drawing certain inferences. This is a consequence of the inferentialist thesis that the meaning of a term is given by its justification through assertibility conditions. Inferential commitments come out from a material notion of inference which underwrites human rational discourse and activity. In this paper I discuss a problem of Brandom’s semantics allegedly exposed in an argument by Paul Boghossian against Dummett’s and Brandom’s substantive conception of (...) meaning. I contend that Boghossian’s analysis is dubious because it overlooks an important difference between Dummett’s and Brandom’s positions related respectively to a monotonic and a non-monotonic view of the norm underwriting meaning.

Within his overarching program aiming to defend an epistemic conception of analyticity, Boghossian (1996 and 1997) has offered a clear-cut explanation of how we can acquire a priori knowledge of logical truths and logical rules through implicit definition. The explanation is based on a special template or general form of argument. Ebert (2005) has argued that an enhanced version of this template is flawed because a segment of it is unable to transmit warrant from its premises to the conclusion. This (...) article aims to defend the template from this objection. We provide an accurate description of the type of non-transmissivity that Ebert attributes to the template and clarify why this is a novel type of non-transmissivity. Then, we argue that Jenkins (2008)’s response to Ebert fails because it focuses on doxastic rather than propositional warrant. Finally, we rebut Ebert’s objection on Boghossian’s behalf by showing that it rests on an unwarranted assumption and is internally incoherent. (shrink)

In this essay, we extend earlier inferentialist-expressivist treatments of traditional logical, semantic, modal, and representational vocabulary (Brandom 1994, 2008, 2015; Peregrin 2014) to explanatory vocabulary. From this perspective, Inference to the Best Explanation (IBE) appears to be an obvious starting point. In its simplest formulation, IBE has the form: A best explains why B, B; so A. It thereby captures one of the central inferential features of explanation. An inferentialist-expressivist treatment of “best explains” would treat it as a logical operator. (...) Analogous to the inferentialist-expressivist treatment of other logical operators, this essay aims to provide introduction and elimination rules for “best explains.” Indeed, by exhibiting a form of detachment, IBE superficially looks like an elimination rule. The sequent calculus LEA+, described in Section 5 below, makes good on this intuition. By showing how “A best explains why B” is related to the underlying, scientific inference “A, so B,” we can purchase the inference ticket of IBE for no more than the cost of science’s material inferences.

This paper aims to unite two seemingly disparate themes in the philosophy of mathematics and language respectively, namely ante rem structuralism and inferentialism. My analysis begins with describing both frameworks in accordance with their genesis in the work of Hilbert. I then draw comparisons between these philosophical views in terms of their similar motivations and similar objections to the referential orthodoxy. I specifically home in on two points of comparison, namely the role of norms and the relation of ontological dependence (...) in both accounts. Lastly, I show that insights from this purported connection can address certain objections to both theories respectively. (shrink)

Abstract: Any normative inferentialist view confronts a set of challenges in the form of how to account for the sort of ordinary empirical descriptive vocabulary that is involved, paradigmatically, in our noninferential perceptual responses and knowledge claims. This chapter lays out that challenge, and then argues that Sellars’ original multilayered account of such noninferential responses in the context of his normative inferentialist semantics and epistemology shows how the inferentialist can plausibly handle those sorts of cases without stretching the notion of (...) inference beyond its standard uses. Finally, it is suggested that for Sellars there were deeply naturalistic motivations for his own normative inferentialism, though the latter raises further questions as to whether this really represents, as Sellars thought, a genuinely scientific naturalist outlook on meaning and conceptual cognition.

In this paper we argue that inferentialist approach to meaning does not, by itself, show that meaning is normative in a prescriptive sense, and that the constitutive rules argument is especially troubling for this position. To show that, we present the proto-inferentialist theory developed by Ajdukiewicz and claim that despite the differences between his theory and contemporary inferentialism rules of language in both theories function more like classificatory devices than prescriptions. Inferentialists can respond by claiming that in their theory meaning (...) is essentially social and hence normative, but we claim that then semantic normativity becomes derivative of social normativity.

Conceptual role semanticists argue that concepts are individuated in terms of their roles in cognition. Some prominent conceptual role semanticists argue for the further claim that concepts are individuated in terms of their rational roles in cognition. This further claim places substantive normative constraints on concept-constitutive roles. I argue that conceptual role semanticists can and should resist the claim that conceptual roles must be specified in inherently normative terms.

Die Idee, daß die Bedeutung sprachlicher Ausdrücke im Rückgriff auf ihren Gebrauch in der Sprache zu klären ist, ist seit Wittgenstein gängig. Das Buch verteidigt diesen Grundgedanken durch die Ausarbeitung einer prozeduralistischen Bedeutungstheorie, die zwei theoretische Strömungen zusammenführt: eine inferentialistische Semantik und eine konventionalistische Sprechakttheorie. Das Buch bietet darüber hinaus eine gründliche Diskussion realistischer und bescheidener Bedeutungstheorien sowie alternativer gebrauchstheoretischer Ansätze.

According to traditional logical expressivism, logical operators allow speakers to explicitly endorse claims that are already implicitly endorsed in their discursive practice — endorsed in virtue of that practice’s having instituted certain logical relations. Here, I propose a different version of logical expressivism, according to which the expressive role of logical operators is explained without invoking logical relations at all, but instead in terms of the expression of discursive-practical attitudes. In defense of this alternative, I present a deflationary account of (...) the expressive role of vocabulary by which we ascribe logical relations. (shrink)

In this paper, I present two tools that help shed light on deep disagreements and their epistemological consequences. First, I argue that we are best off construing deep disagreements as disagreements over conflicting understandings of certain concepts. More specifically, I suggest that deep disagreements are disagreements over how to understand concepts that play what Michael Friedman calls a “constitutive” role for speakers. Second, I argue that we need a better understanding of what speakers are doing when they engage in deep (...) disagreements—what speech acts they are carrying out. I show that we are best off not reducing the relevant speech acts to more familiar speech act kinds, such as assertions or imperatives. I argue that when a speaker articulates an understanding of a concept, they are in part carrying out an act of stipulation. I provide an account of the pragmatics of stipulation and apply the account to examples of deep disagreement. Focusing on the stipulative dimension of deep disagreement opens up, in turn, a novel approach to defusing the epistemological challenges such disagreement seems to pose. (shrink)
