Logical inferentialism holds that the logical constants derive their meanings from their roles in inference. As a form of inferentialism, it contrasts with referentialism, which explains semantic properties in terms of referential relations to worldly objects. This paper explores a novel challenge to inferentialism, namely that its account of the logicality of quantifiers is non-uniform and yields an unattractive pattern of verdicts. Inferentialists accept familiar quantifiers such as the existential quantifier and finite cardinality quantifiers as logical. The (...) challenge arises from the fact that they should reject ‘there are infinitely many’ as logical while at the same time accepting ‘there are uncountably many’ as logical. We examine the assumptions that generate this result and consider potential objections. (shrink)

Logical inferentialism maintains that the formal rules of inference fix the meanings of the logical terms. The categoricity problem points out to the fact that the standard formalizations of classical logic do not uniquely determine the intended meanings of its logical terms, i.e., these formalizations are not categorical. This means that there are different interpretations of the logical terms that are consistent with the relation of logical derivability in a logical calculus. In the case of the quantificational logic, the (...) categoricity problem is generated by the finite nature of the standard calculi and one direction in which it can be solved is to strengthen the deductive systems by adding infinitary rules (such as the ω-rule), i.e., to construct a full formalization. Another main direction is to provide a natural semantics for the standard rules of inference, i.e., a semantics for which these rules are categorical. My aim in this paper is to analyze some recent approaches for solving the categoricity problem and to argue that a logical inferentialist should accept the infinitary rules of inference for the first order quantifiers, since our use of the expressions “all” and “there is” leads us beyond the concrete and finite reasoning, and human beings do sometimes employ infinitary rules of inference in their reasoning.

Inferentialists about scientific representation hold that an apparatus’s representing a target system consists in the apparatus allowing “surrogative inferences” about the target. I argue that a serious problem for inferentialism arises from the fact that many scientific theories and models contain internal inconsistencies. Inferentialism, left unamended, implies that inconsistent scientific models have unlimited representational power, since an inconsistency permits any conclusion to be inferred. I consider a number of ways that inferentialists can respond to this challenge before suggesting (...) my own solution. I develop an analogy to exploitable glitches in a game. Even though inconsistent representational apparatuses may in some sense allow for contradictions to be generated within them, doing so violates the intended function of the apparatus’s parts and hence violates representational “gameplay.”.

This chapter introduces inferential role semantics (IRS) and some of the challenges it faces. It also introduces inferentialism and places it into the wider context of contemporary philosophy of language. The chapter focuses on what is standardly considered both the most important test case for and the most natural application of IRS: logical inferentialism, the view that the meanings of the logical expressions are fully determined by the basic rules for their correct use, and that to understand a (...) logical expression is to use it in accordance with the appropriate rules. It discusses some of the benefits of logical inferentialism, chiefly with regard to the epistemology of logic, and considers a number of objections. The chapter critically examines Robert Brandom's inferentialism about linguistic and conceptual content in general. Finally, it considers a number of general objections to IRS and possible responses on the inferentialist's behalf. (shrink)

Inferentialism is explained as an attempt to provide an account of meaning that is more sensitive (than the tradition of truth-conditional theorizing deriving from Tarski and Davidson) to what is learned when one masters meanings. The logically reformist inferentialism of Dummett and Prawitz is contrasted with the more recent quietist inferentialism of Brandom. Various other issues are highlighted for inferentialism in general, by reference to which different kinds of inferentialism can be characterized. Inferentialism for (...) the logical operators is explained, with special reference to the Principle of Harmony. The statement of that principle in the author’s book _Natural Logic_ is fine-tuned here in the way obviously required in order to bar an interesting would-be counterexample furnished by Crispin Wright, and to stave off any more of the same.

According to the view of conditionals named 'inferentialism', a conditional holds when its consequent can be inferred from its antecedent. This paper identifies some major challenges that inferentialism has to face, and uses them to assess three accounts of conditionals: one is the classical strict account, the other two have recently been proposed by Douven and Rott. As will be shown, none of the three proposals meets all challenges in a fully satisfactory way. We argue through novel formal (...) results that a variation of the evidential account of conditionals suggested by Crupi and Iacona is the most promising candidate to develop inferentialism in a coherent formal framework.

Recent discussions of Artificial Intelligence (AI) safety often invoke the orthogonality thesis—the idea that intelligence and final goals can be independent variables, allowing for the possibility of radically alien AI agents. This paper challenges this view by examining the relationship between language, intentionality, and rational agency against the background of how we now think about Large Language Models (LLMs). Drawing on Robert Brandom’s normative inferentialism and accounts of LLMs as role-playing dialogue agents, we argue that the linguistic competence demonstrated (...) by LLMs suggests significant constraints on their artificial agency. We contend that participation in human discursive practices, which has an inherent normative dimension, may bind specific artificial agents to forms of rationality that are continuous with human reasoning. By analysing recent work on LLM linguistic behaviour, we demonstrate how these systems engage with human normative practices in ways that complicate AI sceptics’ dismissal of LLM capabilities and AI safety theorists’ speculations about future AI agents. We defend Brandom’s approach against charges of insufficient naturalism that could be put forward by the AI safety theorist camp while arguing that his account of language and rationality as inherently social practices provides crucial insights into the nature and potential limits of artificial agency. Our analysis suggests that the development of language-capable AI systems may be constrained by the normative structure of human discursive practices in ways that bind specific quadrants of the space of possible artificial minds.

In this paper I present a novel approach to resolving a problem for inferentialist metasemantic theories that arises from a naturalistic point of view. According to normative inferentialists, expressions have their semantic content in virtue of the inferential rules that govern them. This poses a problem because a rule is a naturalistically suspicious normative notion that is used by normative inferentialists as an explanatory tool. I propose a reconciliation of naturalism and inferentialism by adopting a quasi-realist view on inferential (...) rules. According to this approach, inferential rules viewed externally are considered non-normative constitutive rules that are implicit in the dispositions of a linguistic community to allow and prohibit certain inferences. Conversely, from the internal perspective on linguistic practice, inferential rules are treated as regulative and carry a normative force, i.e., they have an action-guiding character because of the fact that they are individually accepted by members of a linguistic community. (shrink)

The philosophy of language of Robert Brandom is based on a theoretical structure composed of three main elements: the normative analysis of linguistic practices, the inferential characterization of conceptual contents and the expressive articulation of the relations between the former two. Normative pragmatics aims to explain how linguistic practices are sufficient to confer contentful states in those who engage in them. Inferential semantics provides a theory of such pragmatic significances in terms of the inferential relations that articulate conceptual contents. Rational (...) expressivism is the thesis that concept application is essentially a process of turning something that can only be done into something that can also be said. Such a threefold structure is the core of normative inferentialism. This book is a concise, selfcontained and comprehensive presentation of this philosophical enterprise. It guides the reader through the analysis of Brandom’s imposing theoretical apparatus, the discovery of the roots of his approach in American pragmatism and German idealism, till the exploration of some of its most interesting and recent outcomes in pragmatics and semantics. It is a valuable resource for both those who approach Brandom’s work for the first time and those who are interested in the potential of normative inferentialism. (shrink)

The paper presents teleo-inferentialism, which is a novel meta-semantic theory that combines advantages of teleosemantics and normative inferentialism. Like normative inferentialism, teleo-inferentialism holds that contents are individuated by the norms that govern inferences in which they occur. This allows teleo-inferentialism to account for sophisticated concepts. Like teleosemantics, teleo-inferentialism explains conceptual norms in a naturalistically acceptable way by appeal to the broadly biological well-functioning of our innate capacities. As a test-case for teleo-inferentialism, I discuss (...) how the view handles Kripkenstein-style meaning skepticism. (shrink)

There is a felt difference between following an argument to its conclusion and keeping up with an argument in your judgments while failing to see how its conclusion follows from its premises. In the first case there’s what I’m calling an inferential seeming, in the second case there isn’t. Inferential seemings exhibit a cluster of functional and normative characteristics whose integration in one mental state is puzzling. Several recent accounts of inferring suggest inferential seemings play a significant role in the (...) process, but none provides a fully satisfactory understanding of inferential seemings themselves. In this paper I critically examine theoretical options on offer in the existing literature, then develop an alternative view. I discuss implications for recent debates about general principles governing inference, such as Fumerton’s Principle of Inferential Justification and Boghossian’s Taking Condition. (shrink)

This paper addresses the “creeping minimalism” challenge to quasi-realist forms of expressivism by arguing that the solution suggested by Dreier doesn’t work and proposing an alternative solution based on the different inferential roles of ethical and descriptive judgments.

According to Inferentialism, a conditional is true precisely if there is a compelling argument for its consequent starting from its antecedent conjoined with contextually given background knowledge. As a direct consequence of this view, the truth of a conditional’s component parts does not guarantee the truth of the conditional, given that it is compatible with there not being an argument from the conditional’s antecedent to its consequent. Thus, Inferentialism invalidates the principle called Centering, according to which the joint (...) truth of φ and ψ guarantees the truth of “If φ, ψ”. This distinguishes Inferentialism from all standard semantics of conditionals, all of which validate Centering. Here, we report the results from a study that registered (i) participants’ truth evaluations of a set of conditionals; (ii) their truth evaluations of the component parts of those conditionals; (iii) their judgements of the strength of the inferential connection between antecedent and consequent for each conditional; and (iv) their metacognitive confidence in the inference strength judgements. The data from (i)–(iii) allowed us to test Centering and to investigate whether possible violations of the principle can be explained in inferentialist terms. The data from (iv) allowed us to make some progress on testing predictions derived from Hypothetical Inferential Theory, the psychological face of Inferentialism. Our findings show that almost 60% of the relevant responses violated Centering; that participants obeyed Centering only when there was a strong inferential link between true antecedent and true consequent; and that the best models were those that involved inference strength and metacognitive confidence, while the Centering model was weak.

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)

Communication, when defined as an act intended to affect the psychological state of another individual, demands the use of inference. Either the signaler, the recipient, or both must make leaps of understanding which surpass the semantic information available and draw from pragmatic clues to fully imbue and interpret meaning. While research into human communication and the evolution of language has long been comfortable with mentalistic interpretations of communicative exchanges, including rich attributions of mental state, research into animal communication has balked (...) at theoretical models which describe mentalized cognitive mechanisms. We submit a new theoretical perspective on animal communication: the model of inferential communication. For use when existing proximate models of animal communication are not sufficient to fully explain the complex, flexible, and intentional communication documented in certain species, specifically non-human primates, we present our model as a bridge between shallower, less cognitive descriptions of communicative behavior and the perhaps otherwise inaccessible mentalistic interpretations of communication found in theoretical considerations of human language. Inferential communication is a framework that builds on existing evidence of referentiality, intentionality, and social inference in primates. It allows that they might be capable of applying social inferences to a communicative setting, which could explain some of the cognitive processes that enable the complexity and flexibility of primate communication systems. While historical models of animal communication focus on the means-ends process of behavior and apparent cognitive outcomes, inferential communication invites consideration of the mentalistic processes that must underlie those outcomes. We propose a mentalized approach to questions, investigations, and interpretations of non-human primate communication. We include an overview of both ultimate and proximate models of animal communication, which contextualize the role and utility of our inferential communication model, and provide a detailed breakdown of the possible levels of cognitive complexity which could be investigated using this framework. Finally, we present some possible applications of inferential communication in the field of non-human primate communication and highlight the role it could play in advancing progress toward an increasingly precise understanding of the cognitive capabilities of our closest living relatives.

Under what conditions is one justified in believing P on the basis of E? According to Richard Fumerton’s ‘inferential internalism,’ one must have justification for believing that E makes probable P. This chapter proposes that this condition is satisfied by a special sort of appearance, an ‘inferential appearance,’ by which it seems to one that P must be or is likely to be true _in the light of_ E. This account explains the sense in which one must ‘see the connection’ (...) between premises and conclusion, it avoids Lewis Carroll’s problem of Achilles and the Tortoise, and it avoids skepticism about inferential justification. The appearance-based theory is superior to rival theories that appeal to acquaintance, in part because it correctly allows that one can have inferential justification even when no genuine logical relation exists.

Deflationists about truth hold that the function of the truth predicate is to enable us to make certain assertions we could not otherwise make. Pragmatists claim that the utility of negation lies in its role in registering incompatibility. The pragmatist insight about negation has been successfully incorporated into bilateral theories of content, which take the meaning of negation to be inferentially explained in terms of the speech act of rejection. We implement the deflationist insight in a bilateral theory by taking (...) the meaning of the truth predicate to be explained by its inferential relation to assertion. We combine this account of the meaning of the truth predicate with a new diagnosis of the Liar Paradox: its derivation requires the truth rules to preserve evidence, but these rules only preserve commitment. The result is a novel inferential deflationist theory of truth, which solves the Liar Paradox in a principled manner. We end by showing that our theory and simple extensions thereof have the resources to axiomatize the internal logic of several supervaluational hierarchies, including Cantini’s. This solves open problems of Halbach (2011) and Horsten (2011). (shrink)

The aim of this paper is to establish a specific view of linguistic understanding based on the framework of normative inferentialism. Normative inferentialism is presented as an overspecification (rich) account of meaning—the meaning of a sentence is understood as a cluster of context‐dependent contents. The standard psychological mechanism responsible for reaching understanding of an utterance depends on the ability to eliminate contextually irrelevant aspects/parts of meaning. The advantages of the view are that the mechanism can (a) explain a (...) wide range of linguistic phenomena including polysemy, homonymy, and conversational implicatures, and (b) explain partial understanding of an utterance.

Despite its many advantages as a metaethical theory, moral expressivism faces difficulties as a semantic theory of the meaning of moral claims, an issue underscored by the notorious Frege-Geach problem. I consider a distinct metaethical view, inferentialism, which like expressivism rejects a representational account of meaning, but unlike expressivism explains meaning in terms of inferential role instead of expressive function. Drawing on Michael Williams’ recent work on inferential theories of meaning, I argue that an appropriate understanding of the pragmatic (...) role of moral discourse—the facilitation of coordinated social behavior—suggests the kind of inferences we should expect terms with this function to license. I offer a sketch of the inferential roles the moral ‘ought’ plays, and argue that if we accept that the relevant inferential roles are meaning-constitutive, we will be in a position to solve the Frege-Geach problem. Such an inferentialist solution has advantages over those forwarded by expressivists such as Blackburn and Gibbard. First, it offers a more straightforward explanation of the meaning of moral terms. It also gives simple answers to at least two semantic worries that have vexed contemporary expressivists—the “problem of permissions” and the commitment to “mentalism”, both of which I argue are problems that don’t get traction with an inferentialist approach. I conclude by considering ways in which this approach can be expanded into a more robust semantic account. (shrink)

There may be various reasons for claiming that meaning is normative, and additionally, very different senses attached to the claim. However, all such claims have faced fierce resistance from those philosophers who insist that meaning is not normative in any nontrivial sense of the word. In this paper I sketch one particular approach to meaning claiming its normativity and defend it against the anti-normativist critique: namely the approach of Brandomian inferentialism. However, my defense is not restricted to inferentialism (...) in any narrow sense for it encompasses a much broader spectrum of approaches to meaning, connected with the Wittgensteinian and especially Sellarsian view of language as an essentially rule-governed enterprise; and indeed I refrain from claiming that the version of inferentialism I present here is in every detail the version developed by Brandom.

Inferential erotetic logic and inquisitive semantics give accounts of questions and model various aspects of questioning. In this paper we concentrate upon connections between inquisitiveness, being the core concept of INQ, and question raising, characterized in IEL by means of the concepts of question evocation and erotetic implication. We consider the basic system InqB of INQ, remain at the propositional level and show, inter alia, that: a disjunction of all the direct answers to an evoked question is always inquisitive; a (...) formula is inquisitive if, and only if it evokes a yes–no question whose affirmative answer expresses a possibility for the formula; inquisitive formulas evoke questions whose direct answers express all the possibilities for the formulas, and each question erotetically implies a question whose direct answers express the possibilities for the direct answers to the implying question.

In this paper we consider whether a pragmatics of semantic content can be a useful approach to legal interpretation. More broadly speaking, since a pragmatic conception of meaning is a component of inferential semantics, we consider whether an inferentialist approach to legal interpretation can be useful in dealing with some problems of this important aspect of law. In other words, we ask whether Legal Inferentialism is a suitable conception for legal interpretation. In Section 1 we briefly consider the semantics/pragmatics (...) debate in contemporary philosophy of language and in relation to legal interpretation. In Section 2 we discuss the relations between a pragmatics of semantic content and an inferentialist conception of content. In Section 3 we consider how Inferentialism can be applied to legal interpretation. Finally, in Section 4 we consider some possible advantages and drawbacks of Inferentialism applied to legal interpretation and adjudication. (shrink)

This paper defends an inferential conception of scientific representation. It approaches the notion of representation in a deflationary spirit, and minimally characterizes the concept as it appears in science by means of two necessary conditions: its essential directionality and its capacity to allow surrogate reasoning and inference. The conception is defended by showing that it successfully meets the objections that make its competitors, such as isomorphism and similarity, untenable. In addition the inferential conception captures the objectivity of the cognitive representations (...) used by science, it sheds light on their truth and completeness, and it explains the source of the analogy between scientific and artistic modes of representation.

Phenomenal conservatism (PC) is the internalist view that non-inferential justification rests on appearances. PC’s advocates have recently argued that seemings are also required to explain inferential justification. The most general and developed view to this effect is Huemer (2016)’s theory of inferential seemings (ToIS). Moretti (2018) has shown that PC is affected by the problem of reflective awareness, which makes PC open to sceptical challenges. In this paper I argue that ToIS is afflicted by a version of the same problem (...) and it is thus hostage to inferential scepticism. I also suggest a possible response on behalf of ToIS’s advocates.

Most of our memories are inferential, so says Sven Bernecker in Memory: A Philosophical Study. I show that his account of inferentially remembering that p is too strong. A revision of the account that avoids the difficulty is proposed. Since inferential memory that p is memory that q (a proposition distinct from p) with an admixture of inference from one’s memory that q and a true thought one has that r, its analysis presupposes an adequate account of the (presumably non-inferential) (...) memory that q. Bernecker’s account of non-inferentially remembering that is shown to be inadequate. A remedy lies in strengthening the account by requiring the rememberer to have had prima facie justification to believe that q, any defeaters of which were misleading. (shrink)

It is sometimes held that rules of inference determine the meaning of the logical constants: the meaning of, say, conjunction is fully determined by either its introduction or its elimination rules, or both; similarly for the other connectives. In a recent paper, Panu Raatikainen (2008) argues that this view - call it logical inferentialism - is undermined by some "very little known" considerations by Carnap (1943) to the effect that "in a definite sense, it is not true that the (...) standard rules of inference" themselves suffice to "determine the meanings of [the] logical constants" (p. 2). In a nutshell, Carnap showed that the rules allow for non-normal interpretations of negation and disjunction. Raatikainen concludes that "no ordinary formalization of logic ... is sufficient to `fully formalize' all the essential properties of the logical constants" (ibid.). We suggest that this is a mistake. Pace Raatikainen, intuitionists like Dummett and Prawitz need not worry about Carnap's problem. And although bilateral solutions for classical inferentialists - as proposed by Timothy Smiley and Ian Rumfitt - seem inadequate, it is not excluded that classical inferentialists may be in a position to address the problem too.

ABSTRACTThis paper provides a naturalistic account of inference. We posit that the core of inference is constituted by bare inferential transitions, transitions between discursive mental representations guided by rules built into the architecture of cognitive systems. In further developing the concept of BITs, we provide an account of what Boghossian [2014] calls ‘taking’—that is, the appreciation of the rule that guides an inferential transition. We argue that BITs are sufficient for implicit taking, and then, to analyse explicit taking, we posit (...) rich inferential transitions, which are transitions that the subject is disposed to endorse.

In this study two strands of inferentialism are brought together: the philosophical doctrine of Brandom, according to which meanings are generally inferential roles, and the logical doctrine prioritizing proof-theory over model theory and approaching meaning in logical, especially proof-theoretical terms.

In this article, I present two objections against the view that aesthetic judgements – that is, judgemental ascriptions of aesthetic qualities like elegance or harmony – are justified non‐inferentially. The first is that this view cannot make sense of our practice to support our aesthetic judgements by reference to lower‐level features of the objects concerned. The second objection maintains that non‐inferentialism about the justification of aesthetic judgements cannot explain why our aesthetic interest in artworks and other objects is limited (...) to only some of their lower‐level features that realise their higher‐level aesthetic qualities. Although my concern with the view that aesthetic judgements are subject to non‐inferential justification is very general, my discussion is primarily structured around Sibley's well‐developed and influential version of this view.

Normative inferentialism is a semantic theory according to which the meaning of an expression is, or is determined by, its proper inferential role. Critics of inferentialism often argue that it violates the principle of compositionality, and that it is therefore unable to explain some important linguistic data. I have two tasks in this paper: the first is to demonstrate that inferentialism, appearances perhaps to the contrary, does not violate the principle of compositionality, and the second is to (...) explain why this demonstration is unlikely to mollify critics of inferentialism. The dispute between inferentialists and their critics, I shall argue, is not about compositionality, it is a more fundamental dispute about the nature of representations. (shrink)

Quentin Skinner’s appropriation of speech act theory for intellectual history has been extremely influential. Even as the model continues to be important for historians, however, philosophers now regard the original speech act theory paradigm as dated. Are there more recent initiatives that might reignite theoretical work in this area? This article argues that the inferentialism of Robert Brandom is one of the most interesting contemporary philosophical projects with historical implications. It shows how Brandom’s work emerged out of the broad (...) shift in the philosophy of language from semantics to pragmatics that also informed speech act theory. The article then goes on to unpack the rich implications of Brandom’s inferentialism for the theory and practice of intellectual history. It contends that inferentialism clarifies, legitimizes, and informs intellectual historical practice, and it concludes with a consideration of the challenges faced by inferentialist intellectual history, together with an argument for the broader implications of Brandom’s work.

The Gettier Problem, when properly understood, has a straightforward solution. My main thesis—my ‘Gettier conjecture’—is that gettierized subjects fail to know in virtue of their justified true belief depending causally and evidentially on something they fail to know. Inferential knowledge (i.e., knowledge of a conclusion) requires knowledge of all the premises on which one’s conclusion depends causally and evidentially. This chapter is a first effort in trying to support this thesis. Section 2 discusses the Gettier conjecture, the notions of evidential (...) and causal dependence, and applies the conjecture to the original Gettier cases. Section 3 looks at two objections: the claims that the conjecture fails to deal with all Gettier cases and that the Gettier Problem is a philosophical ‘dead end.’ In Section 4 I offer further support for the conjecture by situating it within a knowledge-first framework.

Normative discourse includes statements which appear to be truth-apt expressions of normative beliefs. But normative oughts do not seem to fit cleanly amongst the natural facts. This makes many naturalistically inclined philosophers sympathetic to some form of expressivist view that normative statements get their meaning from how they express desire-like attitudes. However, there are a serious semantic challenges for expressivism, which lead others to accept the idea that normative statements are representational of reality after all. This paper presents another option (...) that derives from the general program in the theory of meaning to emphasize the commissive role of language over any descriptive or expressive roles. Here this emphasis is used to sketch a version of metaethical inferentialism and contrast it with expressivism. I conclude with some observations about new perspectives this view offers on three other issues in metaethics. (shrink)

I develop an inferential account of collective self-knowledge. Starting with the assumption that groups have (at least propositional) attitudes I look at desiderata for any account of collective self-knowledge of such attitudes. Any such account has to explain the features that group avowals have in our ordinary linguistic practice. Moreover, any account ought to be compatible with as many views of group attitudes as possible. I propose a new account that looks at attitude-forming processes of groups as evidence for collective (...) self-knowledge. It is based on forward-looking inferences in contrast to the backwards-looking conception commonly found in inferential accounts of self-knowledge in individuals. I then show that groups have a minimal form of privileged and peculiar access to their own attitudes because they have easy access to their own production of attitudes as evidence. (shrink)

One’s account of the meaning of ethical sentences should fit – roughly, as part to whole – with one’s account of the meaning of sentences in general. When we ask, though, where one widely discussed account of the meaning of ethical sentences fits with more general accounts of meaning, the answer is frustratingly unclear. The account I have in mind is the sort of metaethical expressivism inspired by Ayer, Stevenson, and Hare, and defended and worked out in more detail recently (...) by Blackburn, Gibbard, and others. So, my first aim (§1) in this paper is to pose this question about expressivism’s commitments in the theory of meaning and to characterize the answer I think is most natural, given the place expressivist accounts attempt to occupy metaethics. This involves appeal to an ideationalist account of meaning. Unfortunately for the expressivist, however, this answer generates a problem; it’s my second aim (§2) to articulate this problem. Then, my third aim (§3) is to argue that this problem doesn’t extend to the sort of account of the meaning of ethical claims that I favor, which is like expressivism in rejecting a representationalist order of semantic explanation but unlike expressivism in basing an alternative order of semantic explanation on inferential role rather than expressive function.

This paper sets out an inferentialist approach to abstract objects—arguing that it provides a deflationary account of abstracta—and draws attention to some distinctive and attractive features of the account. In brief, a consequence of the kind of semantic inferentialism developed by Brandom is that quantifiers are essentially sortally restricted. As a result, there is a plurality of particular quantifiers, a plurality of senses of ‘exists’, and a plurality of kinds of existence. The inferentialist litmus test for which senses of (...) ‘exists’ are ‘ontologically robust’ or ‘weightless’, I argue, is whether the standards of correctness and incorrectness for existence claims are internal to the linguistic practice itself, or are, in some part, external to the linguistic practice. In the former case, existence claims are responsible only to the internal rules of the linguistic practice and are ontologically weightless. In the latter case, existence claims are responsible to worldly facts and are ontologically robust. On this account, ordinary empirical claims (for example) are ontologically robust, whereas claims about mathematical objects (for example) are ontologically weightless. (shrink)

This article explores how Robert Brandom's original “inferentialist” philosophical framework should be positioned with respect to the classical pragmatist tradition. It is argued that Charles Peirce's original attack (in “Questions Concerning Certain Faculties Claimed for Man” and other early papers) on the use of “intuition” in nineteenth‐century philosophy of mind is in fact a form of inferentialism, and thus an antecedent relatively unexplored by Brandom in his otherwise comprehensive and illuminating “tales of the mighty dead.” However, whereas Brandom stops (...) short at a merely “strong” inferentialism, which admits some non‐inferential mental content (although it is parasitic on the inferential and can only be “inferentially articulated”), Peirce embraces a total, that is, “hyper‐,” inferentialism. Some consequences of this difference are explored, and Peirce's more thoroughgoing position is defended. (shrink)

A number of people have recently argued for a structural approach to accounting for the applications of mathematics. Such an approach has been called "the mapping account". According to this view, the applicability of mathematics is fully accounted for by appreciating the relevant structural similarities between the empirical system under study and the mathematics used in the investigation ofthat system. This account of applications requires the truth of applied mathematical assertions, but it does not require the existence of mathematical objects. (...) In this paper, we discuss the shortcomings of this account, and show how these shortcomings can be overcome by a broader view of the application of mathematics: the inferential conception. (shrink)

In a paper published in this journal Reinikainen (forthcoming) argues that my version of inferentialism “faces a problem concerning the determination of linguistic meaning”, which “essentially emerges from troubles in understanding, in inferentialist terms, how the world is ‘embodied’ in language”. As far as I can see, his argument is based on a misunderstanding of what my inferentialism amounts to. I explain what I mean.

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.

Highly idealized models may serve various epistemic functions, notably explanation, in virtue of representing the world. Inferentialism provides a prima facie compelling characterization of what constitutes the representation relation. In this paper, I argue that what I call factive inferentialism does not provide a satisfactory solution to the puzzle of model-based—factive—explanation. In particular, I show that making explanatory counterfactual inferences is not a sufficient guide for accurate representation, factivity, or realism. I conclude by calling for a more explicit (...) specification of model-world mismatches and properties imputation. (shrink)

In this paper, I will analyze how the conceptualization of the term ‘Basqueness’, and the meaning of ‘being Basque’, have been instrumental in determining the way in which citizens of the Basque Autonomous Community (BAC) have chosen to identify themselves. What it means to be Basque has experienced a significant evolution from its ethnic and linguistic origins to being a matter of feeling and doing; however, the way Basque citizens felt about Basqueness, and what actions participated in Basqueness, was substantially (...) influenced by the climate of political polarization, the appropriation by nationalism of Basque symbols and features and the violence of terrorist organization ETA, as well as the justification of its crimes. Working from the semantic theory of Brandomian inferentialism, I want to show how these factors functioned as inferential relations that constituted the meaning of Basqueness. As these inferences changed with the dissolution of ETA and the easing of political polarization, what it means to be Basque has subsequently changed its meaning, which might contribute to explaining why in recent years an increasing number of people in the BAC have incorporated Basqueness into their mixed or liminal identities.

The semantic inferentialist account of the social institution of semantic meaning can be naturally extended to account for social ontology. I argue here that semantic inferentialism provides a framework within which mathematical ontology can be understood as social ontology, and mathematical facts as socially instituted facts. I argue further that the semantic inferentialist framework provides resources to underpin at least some aspects of the objectivity of mathematics, even when the truth of mathematical claims is understood as socially instituted.

In this chapter, I explain what is at issue in the debate on the meaning of the logical constants, exposing some weaknesses of the standard way in which logicians approach this subject. I present and discuss the two families of proposals that have been most successful: invariantism, which derives from (Tarski. History Philos Logic, 7, 143–154, 1986), and inferentialism, which derives from (Gentzen. Am Philosoph Quart 1(4), 288–306 1935/1964) and whose more philosophical aspects have been developed by Dummett, Hacking (...) and Prawitz (Dummett M (1973) Frege. Philosophy of Language. New York, Harper and Row Publishers; Dummett M (1991) The logical basis of metaphysics. Cambridge, MA., Harvard University Press; Hacking. J Philos 76, 285–319 (1979); Prawitz. Synthese 148, 507–524 (2006)). I show that neither of these two approaches gets the set of logical constants right. Both have been accused of overgenerating, i.e. including notions that intuitively are not logical constants, and of undergenerating, i.e. leaving out of the picture some notions that clearly are logical constants. The constraints that their supporters have proposed to make them extensionally adequate point in the direction of taking on board the pragmatic roles that these notions play in communication. The last section of this chapter is devoted to explaining how a pragmatist account helps us to overcome the difficulties that more formalist approaches present, be they purely syntactic or semantically guided.

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)

Review of the book "Robert Brandom's Normative Inferentialism" by Giacomo Turbanti.

Robert Brandom has supported his inferentialist conception of semantic content by appealing to the claim that it is a necessary condition on having a propositional attitude that one appreciate the inferential relations it stands in. When we see what considerations can be given in support of that claim, however, we see that it doesn’t even motivate an inferentialist semantics. The problem is that that claim about what it takes to have a propositional attitude does nothing to show that its inferential (...) relations are a feature of its content rather than of the relation that the subject stands in to that content—that is, the attitude.

In a recent paper, after outlining various distinguishing features of derogatory words, Jennifer Hornsby suggests that the phenomenon raises serious difficulties for inferentialism. Against Hornsby, I claim that derogatory words do not pose any insuperable problems for inferentialism, so long as it is supplemented with apparatus borrowed from Grice and Hare. Moreover, I argue, derogatory expressions pose difficulties for Hornsby's favoured alternative theory of meaning, representationalism, unless it too is conjoined with a similar Grice/Hare mechanism. So, the upshot (...) of the discussion is that, contra Hornsby, focus on derogatory expressions alone does not provide grounds for deciding between competing theories of meaning, but nevertheless serves to highlight important features that any such theory must acknowledge and incorporate.
