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)

The basic idea of logical expressivism in the Brandomian tradition is that logic makes inferential relations explicit and thereby accessible to critical discussion. But expressivists have not given a convincing explanation of what the point of logical theories is. Peregrin provides a starting point by observing a distinction between making explicit and explication in Carnap’s sense of replacing something unclear and vague by something clear and exact. Whereas logical locutions make inferential relations explicit within a language, (...) logical theories use formal languages to explicate inferential roles and meanings of ordinary-language expressions. But Peregrin also holds that the whole point of logical theories is to provide perspicuous models of inferential structures in ordinary language practice. This turns explication into a mere continuation of making explicit by other means, and it leads to a one-sided conception of logic which has no room for evaluating inferential practice in light of logical theories. As a more convincing alternative, I suggest that expressivists rely on the method of reflective equilibrium. This approach is closely related to Carnapian explication, but it has the potential of correcting informal inferential practice without dubious ambitions to replace ordinary languages by logical formalisms.

In this paper, I address a key argument in favour of logical expressivism, the view that knowing a logical principle such as Modus Ponens is not a cognitive state but a pro-attitude towards drawing certain types of conclusions from certain types of premises. The argument is that logical expressivism is the only view that can take us out of Lewis Carroll's Regress – which suggests that elementary deductive reasoning is impossible. I show that the argument (...) does not hold scrutiny and that logical cognitivism can be vindicated. In the course of the discussion, I draw substantially on a comparison with a similar argument in meta-ethics, for moral expressivism. (shrink)

This paper explores some of the assumptions orienting the debate about logical pluralism. I argue that these assumptions are grounded in the truth-conditional character of the semantic metavocabularies in which the debate is conducted. Then, I suggest an expressivist strategy to reinterpret the pluralist claim that there are different logics and I show how the expressive role of logical vocabularies can be equally well characterized by means of different expressive resources not involving the notion of truth.

This paper aims to develop the implications of logical expressivism for a theory of dialogue coherence. I proceed in three steps. Firstly, certain structural properties of cooperative dialogue are identified. Secondly, I describe a variant of the multi-agent natural deduction calculus that I introduced in Piwek (J Logic Lang Inf 16(4):403–421, 2007 ) and demonstrate how it accounts for the aforementioned structures. Thirdly, I examine how the aforementioned system can be used to formalise an expressivist account of (...) class='Hi'>logical vocabulary that is inspired by Brandom (Making it explicit: reasoning, representing, and discursive commitment, 1994 ; Articulating reasons: an introduction to inferentialism, 2000 ). This account conceives of the logical vocabulary as a tool which allows speakers to describe the inferential practices which underlie their language use, i.e., it allows them to make those practices explicit. The rewards of this exercise are twofold: (1) We obtain a more precise account of logical expressivism which can be defended more effectively against the critique that such accounts lead to cultural relativism. (2) The formalised distinction between engaging in a practice and expressing it, opens the way for a revision of the theory of dialogue coherence. This revision eliminates the need for logically complex formulae to account for certain structural properties of cooperative dialogue. (shrink)

P.F. Strawson contributed to many philosophical domains, including the philosophy of language, the history of philosophy, metaphysics, moral philosophy and philosophical methodology. Most of his contributions in these areas have influenced contemporary debates, either because his views are still defended or because they are still considered worthy of detailed responses. His views on the philosophy of logic have been only rarely discussed, however. My aim in this paper is threefold. First, I provide a systematic account of Strawson’s philosophy of logic. (...) I argue that Strawson is an important predecessor of logical expressivism, a contemporary position in the philosophy of logic most notably defended by Robert Brandom. My main focus is on Strawson’s largely-neglected 1982 paper ‘Logical Form and Logical Constants’, which contains his most mature ideas on the topic. Second, while Strawson’s position is of historical and independent philosophical interest, I argue that he leaves many points unclear. Finally, I propose several clarifications of Strawson’s position. (shrink)

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). (shrink)

In this paper I construct a system of semantics for classical and intuitionistic propositional logic based on epistemic norms governing belief expansion. Working in the AGM-framework of belief change, I give a generalisation of Gärdenfors’ notion of belief systems which can be defined without reference to a logical consequence operator by using a version of the Ramsey Test. These belief expansion systems can then be used to define epistemic models which are sound and complete for either classical or intuitionistic (...) propositional logic depending on which of the two notions of epistemic validity, identified by Levi and Arló-Costa, is used. Finally, I offer a discussion on how these results can be understood as providing a model theory within the framework of logical expressivism. (shrink)

Contemporary discussions of expressivism in metaethics tend to run together two quite different antidescriptivist views, and only one of them is subject to the objection about compositional semantics pressed most recently by Schroeder (following Dreier, Unwinn, Hale, Geach and others). Here I distinguish the two versions of expressivism and then go on to suggest that those sympathetic to the second sort of expressivism might improve their account of normative vocabulary and the way it figures in reasoning by (...) making what may seem like a somewhat surprising comparison between normative vocabulary and logical vocabulary. I argue that this comparison brings into view the initial steps towards a third antidescriptivist view in metaethics, which we may see as a pragmatist improvement on the second version of expressivism. (shrink)

In this paper, using Mark Schroeder’s (2008a) expressivist semantic framework for normative language as a case study, I will identify difficulties that even an expressivist semantic theory capable of addressing the Frege-Geach problem will encounter in handling the logical possibility of moral dilemmas. To this end, I will draw on a classical puzzle formulated by McConnell (1978) that the logical possibility of moral dilemmas conflicts with some of the prima facie plausible axioms of the standard deontic logic, which (...) include obligation implies permission. On the tentative assumption that proponents of ethical expressivism should be generally committed to securing the logical possibility of moral dilemmas in their semantic theories, I will explore whether and how expressivists can successfully invalidate obligation implies permission within the framework developed by Schroeder. The case study eventually reveals that this can indeed be a hard task for expressivists. Generalizing from the case study, I will suggest that the source of the difficulty ultimately lies in the mentalist assumption of the expressivist semantic project that the logico-semantic relations exhibited by normative sentences should be modeled in terms of the psychological attitudes that speakers express by uttering them. My final goal will be to show that the difficulty expressivists face in dealing with the logical possibility of moral dilemmas is a reflection of the more general problem that their commitment to the mentalist assumption prevents them from flexibly adopting or dropping axioms in their semantic theories to get the right technical results.

This paper discusses a generalization of logical expressivism. It is shown that, in the wide sense defined here, the expressivist approach is neutral with respect to different theories of inference and offers a natural framework for understanding logical forms and their function. An expressivist strategy for explaining the development of logical forms is then applied to the analysis of Frege’s Begriffsschrift, Gentzen’s sequent calculus and Belnap’s display logic.

Expressivist analyses of evaluative discourse characterize unembedded moral claims as functioning primarily to express noncognitive attitudes. The most thorny problem for this project has been explaining the logical relations between such evaluative judgements and other judgements expressed using evaluative terms in unasserted contexts, such as when moral judgements are embedded in conditionals. One strategy for solving the problem derives logical relations among moral judgements from relations of "consistency" and "inconsistency" which hold between the attitudes they express. This approach (...) has been accused of conflating inconsistency with mere pragmatic incoherence. In reaction such criticisms several recent theorists have attempted to use alternative resources. The most sophisticated noncognitivists have often propounded theories with secondary descriptive components in addition to their primary expressive meanings. Recent independent suggestions by Frank Jackson and Stephen Barker attempt to solve the embedding problem by utilizing such descriptive components of moral utterances. Unfortunately, this strategy fails to handle a certain sort of example using just the descriptive resources available to noncognitivists. For it must rule valid arguments invalid in virtue of equivocation in the secondary descriptive meanings. The present paper explains the problem and suggests a moral for expressivist theories.

The connectives of classical propositional logic are given an analysis in terms of necessary and sufficient conditions of acceptance and rejection, i.e. the connectives are analyzed within an expressivist bilateral meaning-is-use framework. It is explained how such a framework differs from standard inferentialist frameworks and it is argued that it is better suited to address the particular issues raised by the expressivist thesis that the meaning of a sentence is determined by the mental state that it is conventionally used to (...) express. Furthermore, it is shown that the classical requirements governing the connectives completely characterize classical logic, are conservative and separable, are in bilateral harmony, are structurally preservative with respect to the classical coordination requirements and resolve the categoricity problem. These results are taken to show that one can give an expressivist bilateral meaning-is-use analysis of the connectives that confer on them a determinate coherent classical interpretation. (shrink)

Various attempts at demarcating logic were undertaken, many of them based on specific understanding of how logical knowledge is formal and not material. MacFarlane has persuasively shown that general idea of formality of logic can be understood in various ways. I take two of the accounts of formality, namely the requirement of conservativity and the requirement of schematicity of logical vocabulary, into consideration as promising candidates to make the all too unclear notion of formality more precise and study (...) to what degree they could be considered as either necessary or sufficient conditions for logicality of some piece of vocabulary. Finding both notion unsatisfactory, as they stand, I propose combining them and envisage a hierarchy of logicality of expressions of a given language. Such a hierarchy is complicated and not linear, yet still offers a valuable explication of both the range and pragmatic significance of logic, if we combine it with logical expressivism. (shrink)

On an expressivist view, ethical claims are understood as expressions of our attitudes, desires, and feelings. A famous puzzle for this view concerns the use of logic in ethical reasoning, and two standard treatments try to solve the puzzle by explaining logical inconsistency in terms of conflicting attitudes. I argue, however, that this general strategy fails: because we can reason effectively even in the presence of conflicting moral attitudes – in cases of moral dilemmas – avoiding these conflicts cannot (...) be a ground for correct moral reasoning. The result is a dilemma for expressivists: if they take all kinds of attitudes to be under consideration, then conflict cannot play the required role, since attitudes can fail to be compatible in cases of moral conflict. If they restrict attention to ‘all-in attitudes’ or to intentions or plans, then there is an important notion of obligation, used in standard arguments – one for which conflicts are allowed – that they fail to capture. I explain why expressivists should be especially tolerant of conflicting attitudes, and I conclude that they should pursue a different strategy for grounding logical normativity. (shrink)

In this paper I offer solutions to two problems which our moral practice engenders for expressivism, the meta-ethical doctrine according to which ethical statements aren't propositional, susceptible of truth and falsity, but, rather, express the speaker's non-cognitive attitudes. First, the expressivist must show that arguments which are valid when interpreted propositionally are valid when construed expressivistically, and vice versa. The second difficulty is the Frege-Geach problem. Moral arguments employ atomic sentences, negations, disjunctions, etc., and, by expressivist lights, the meaning (...) of a moral sentence depends on the attitude that it expresses. Since one's attitude varies as one asserts a claim, or negates it, or cites it as a disjunct, etc., the meaning of the relevant phrase changes as well, so the argument equivocates. (Formal proofs are provided in appendices to the paper.). (shrink)

It is argued that expressivists can solve their problems in accounting for the unity and autonomy of logic – logic is topic independent and does not derive from a general ‘logic’ of mental states – by adopting an analysis of the logical connectives that takes logically complex sentences to express complex combinations of simple attitudes like belief and disapproval and dispositions to form such simple attitudes upon performing suppositional acts, and taking acceptance and rejection of sentences to be the (...) common mental denominator in descriptive and evaluative discourse, and structural requirements governing these to be the basis for logic. Such an account requires that attitudes like belief, intention and disapproval can come in hypothetical mode – plausibly linked to the capacity to mentally simulate or emulate one's own attitudes – and, if correct, suggests that these form the basic building blocks for our capacity to understand logically complex sentences.

This article aims to show that the incompatibility between the application of logic to norms and values and the expressive conception of these notions – basically summed up by the Frege–Geach problem – can be overcome. To this end, a logic is constructed for the expressive conception of norms and values which provides a solution to the Frege–Geach problem and is not affected by the limitations that occur in some previous attempts. More specifically, a pragmatic language LP is introduced which (...) is an extension of the language L of standard propositional logic, obtained by adding two categories of logical-pragmatic signs to the vocabulary of L: the signs of pragmatic mood (,,, standing for assertion, obligation and approval, respectively) and the pragmatic connectives (∼, ∩, ∪, ⊃, ≡, standing for pragmatic negation, conjunction, disjunction, implication and bi-implication, respectively). The notions of pragmatic validity, consistency (satisfiability), compatibility, equivalence and inference are then defined, and some criteria of pragmatic validity are given. It is thus possible to carry out in LP inferences on norms and values expressively understood, adequately formalizing Geach's problematic inferences. (shrink)

This paper provides finitary jointly necessary and sufficient acceptance and rejection conditions for the logical constants of a first order quantificational language. By introducing the notion of making an assignment as a distinct object level practice—something you do with a sentence—(as opposed to a meta-level semantic notion) and combining this with the practice of (hypothetical and categorical) acceptance and rejection and the practice of making suppositions one gains a structure that is sufficiently rich to fully characterize the class of (...) classical first order theories. The analysis thus provides a way of characterizing classical first order quantification by expressivist means. (shrink)

The basic idea of expressivism is that for some sentences ‘P’, believing that P is not just a matter of having an ordinary descriptive belief. This is a way of capturing the idea that the meaning of some sentences either exceeds their factual/descriptive content or doesn’t consist in any particular factual/descriptive content at all, even in context. The paradigmatic application for expressivism is within metaethics, and holds that believing that stealing is wrong involves having some kind of desire-like (...) attitude, with world-tomind direction of fit, either in place of, or in addition to, being in a representational state of mind with mind-to-world direction of fit. Because expressivists refer to the state of believing that P as the state of mind ‘expressed’ by ‘P’, this view can also be described as the view that ‘stealing is wrong’ expresses a state of mind that involves a desire-like attitude instead of, or in addition to, a representational state of mind. According to some expressivists - unrestrained expressivists, as I’ll call them - there need be no special relationship among the different kinds of state of mind that can be expressed by sentences. Pick your favorite state of mind, the unrestrained expressivist allows, and there could, at least in principle, be a sentence that expressed it. Expressivists who seem to have been unrestrained plausibly include Ayer in Language, Truth, and Logic, and Simon Blackburn in many of his writings, including his [1984], [1993], and.. (shrink)

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)

Mark Schroeder has argued that all reasonable forms of inconsistency of attitude consist of having the same attitude type towards a pair of inconsistent contents (A-type inconsistency). We suggest that he is mistaken in this, offering a number of intuitive examples of pairs of distinct attitudes types with consistent contents which are intuitively inconsistent (B-type inconsistency). We further argue that, despite the virtues of Schroeder's elegant A-type expressivist semantics, B-type inconsistency is in many ways the more natural choice in developing (...) an expressivist account of moral discourse. We close by showing how to adapt ordinary formality-based accounts of logicality to define a B-type account of logical inconsistency and distinguish it from both semantic and pragmatic inconsistency. In sum, we provide a roadmap of how to develop a successful B-type expressivism. (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 (...) class='Hi'>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.

Expressivists have a problem with negation. The problem is that they have not, to date, been able to explain why ‘murdering is wrong’ and ‘murdering is not wrong’ are inconsistent sentences. In this paper, I explain the nature of the problem, and why the best efforts of Gibbard, Dreier, and Horgan and Timmons don’t solve it. Then I show how to diagnose where the problem comes from, and consequently how it is possible for expressivists to solve it. Expressivists should accept (...) this solution, I argue, because it is demonstrably the only way of avoiding the problem, and because it generalizes. Once we see how to solve the negation problem, I show, it becomes easy to state a constructive, compositional expressivist semantics for a purely normative language with the expressive power of propositional logic, in which we can for the first time give explanatory, formally adequate expressivist accounts of logical inconsistency, logical entailment, and logical validity. As a corollary, I give what I take to be the first real expressivist explanation of why Geach’s original moral modus ponens argument is genuinely logically valid. This proves that the problem with expressivism cannot be that it can’t account for the logical properties of complex normative sentences. But it does not show that the same solution can work for a language with both normative and descriptive predicates, let alone that expressivists are able to deal with more complex linguistic constructions like tense, modals, or even quantifiers. In the final section, I show what kind of constraints the solution offered here would place expressivists under, in answering these further questions. (shrink)

What is morality? In Practical Expressivism, I argue that morality is a purely natural interpersonal co-ordination device, whereby human beings express their attitudes in order to influence the attitudes and actions of others. -/- The ultimate goal of these expressions is to find acceptable ways of living together. This 'expressivist' model for understanding morality faces well-known challenges concerning 'saving the appearances' of morality, because morality presents itself to us as a practice of objective discovery, not pure expression. -/- This (...) book demonstrates how a properly developed expressivist view can overcome this objection, by showing that even if moral practice is fundamentally expressive, it can still come to possess those features that make it appear objective (features such as talk and thought of moral disagreement, truth and belief, and the applicability of logical notions to moral sentences). The key to this development is to emphasise the unique and intricate practical role that morality plays in our lives. Practical expressivism is also practical in the further sense that it provides repeatable patterns that expressivists can deploy in coming to understand the apparently objective features of morality. (shrink)

Simon Blackburn’s expressivist logic of attitudes aims to explain how we can use non-assertoric moral judgements in logically valid arguments. Patricia Marino has recently argued that Blackburn’s logic faces a dilemma: either it cannot account for the place of moral dilemmas in moral reasoning or, if it can, it makes an illicit distinction between two different kinds of moral dilemma. Her target is the logic’s definition of validity as satisfiability, according to which validity requires an avoidance of attitudinal inconsistency. Against (...) Marino’s arguments, I contend that expressivists following Blackburn are able to show how we appreciate the validity of arguments found in dilemma-contexts, and that Marino’s argument concerning the distinction between contingent moral dilemmas and logical moral dilemmas rests on a mistake concerning the logical representation of a contingent dilemma.

A globally expressivist analysis of the indicative conditional based on the Ramsey Test is presented. The analysis is a form of ‘global’ expressivism in that it supplies acceptance and rejection conditions for all the sentence forming connectives of propositional logic (negation, disjunction, etc.) and so allows the conditional to embed in arbitrarily complex sentences (thus avoiding the Frege–Geach problem). The expressivist framework is semantically characterized in a restrictor semantics due to Vann McGee, and is completely axiomatized in a logic (...) dubbed ICL (‘Indicative Conditional Logic’). The expressivist framework extends the AGM (after Alchourron, Gärdenfors, Makinson) framework for belief revision and so provides a categorical (‘yes’–‘no’) epistemology for conditionals that complements McGee’s probabilistic framework while drawing on the same semantics. The result is an account of the semantics and acceptability conditions of the indicative conditional that fits well with the linguistic data (as pooled by linguists and from psychological experiments) while integrating both expressivist and semanticist perspectives. (shrink)

In chapter five of Wise Choices, Apt Feelings Allan Gibbard develops what he calls a ‘normative logic’ intended to solve some problems that face an expressivist theory of norms like his. The first is “the problem of embedding: The analysis applies to simple contexts, in which it is simply asserted or denied that such-and-such is rational. It says nothing about more complex normative assertions.”1 That is the problem with which I will be concerned. Though he doesn’t list it as one (...) of the problems to be solved, Gibbard’s devices also explain what it means to say that a certain normative argument is ‘valid’, that one normative statement follows from some others. Both of these questions arise because of the ways we ordinarily think and speak, ways which on a simplistic version of expressivism appear not to make any sense. An expressivist committed to making sense of the way we ordinarily think and speak in normative language owes some account of embeddings and of logic. Gibbard’s device seems to me the clearest and most systematic of any expressivist attempt to meet these challenges. (shrink)

Ecumenical views in metaethics hold that normative utterances express hybrid mental states, states which include both a cognitive and a conative component. The ecumenicist can have her cake and eat it too: the view reaps the benefits of both cognitivist and non-cognitivist theories of normative judgement. The conative component of normative judgements accounts for their necessary link with motivation and rational action. The cognitive component makes it possible for the ecumenicist to endorse expressivism without facing the most difficult Frege-Geach (...) challenges. Ridge (2014) provides a defence of ecumenical expressivism about practical normativity that is both ambitious and compelling. I discuss and try to challenge two (unrelated) parts of the view. In the first section, I’ll raise a question for Ridge’s strategy for addressing the Frege-Geach problem, and in particular his proposed recipe for how to interpret normative assertions of arbitrary logical complexity. Then I discuss Ridge’s defence of cognitivism about rationality. I try to highlight some considerations that make expressivism about theoretical and practical rationality attractive. (shrink)

I am presenting a sequent calculus that extends a nonmonotonic consequence relation over an atomic language to a logically complex language. The system is in line with two guiding philosophical ideas: (i) logical inferentialism and (ii) logical expressivism. The extension defined by the sequent rules is conservative. The conditional tracks the consequence relation and negation tracks incoherence. Besides the ordinary propositional connectives, the sequent calculus introduces a new kind of modal operator that marks implications that hold monotonically. (...) Transitivity fails, but for good reasons. Intuitionism and classical logic can easily be recovered from the system. (shrink)

This book presents a philosophical conception of logic -- "logical expressivism"-- according to which the role of logic is to make explicit reason relations, which are often neither monotonic nor transitive. It reveals new perspectives on inferential roles, sequent calculi, representation, truthmakers, and many extant logical theories.

Geach's problem, the problem of accounting for the fact that judgements expressed using moral terms function logically like other judgements, stands in the way of most noncognitive analyses of moral judgements. The non-cognitivist must offer a plausible interpretation of such terms when they appear in conditionals that also explains their logical interaction with straightforward moral assertions. Blackburn and Gibbard have offered a series of accounts each of which interprets such conditionals as expressing higher order commitments. Each then invokes norms (...) for the coherent acceptance of attitudes to explain why we hold certain combinations inconsistent. Against these accounts the paper presses two related objections: (1) The norms needed to do the explanatory work cannot be strong enough to do that work without also ruling clearly consistent attitudes inconsistent. And (2), the norms of rational attitude acceptance do not neatly track the distinction between consistent and inconsistent attitudes. (shrink)

Robert Brandom defends the intelligibility of the notion of a fully discursive practice that does not include any kind of logical vocabulary. Logical vocabulary, according to his account, should be understood as an optional extra to discursive practice, not as a necessary ingredient. Call this the Layer Cake Picture of the relation of logical to non-logical discursive practices. The aim pursued in this paper is to show, by way of an internal critique, that the Layer Cake (...) Picture is in fact incompatible with the most central claims of Brandom’s philosophy. A way is sketched how to give up the Layer Cake Picture and still hold on to a position that is central to Brandom’s philosophical outlook, namely his expressivism about logic. (shrink)

This volume investigates Eric Weil’s innovative conceptualization of the place of violence in the philosophical tradition with a focus on violence’s relationship to language and to discourse. Weil presents violence as the central philosophical problem. According to this reading, the western philosophical tradition commonly conceptualizes violence as an expression of error or as a consequence of the weakness of will. However, by doing so, it misses something essential about the role that violence plays in our conceptual development as well as (...) the place violence holds in our discursive practices. The author draws comparisons between Weil’s work and that of Robert Brandom. Brandom’s inferentialism creates a sophisticated program at the junction of pragmatics and semantics, philosophy of language, logic, and philosophy of mind. The monograph builds on these insights in order to show how an inferentialist reading of Eric Weil is fruitful for both Weilian studies and for inferentialism. This volume will notably be of interest to scholars in philosophy, argumentation theory, and communication studies. (shrink)

This paper aims to provide a mathematically tractable background against which to model both modal cognitivism and modal expressivism. I argue that epistemic modal algebras, endowed with a hyperintensional, topic-sensitive epistemic two-dimensional truthmaker semantics, comprise a materially adequate fragment of the language of thought. I demonstrate, then, how modal expressivism can be regimented by modal coalgebraic automata, to which the above epistemic modal algebras are categorically dual. I examine five methods for modeling the dynamics of conceptual engineering for (...) intensions and hyperintensions. I develop a novel topic-sensitive truthmaker semantics for dynamic epistemic logic, and develop a novel dynamic epistemic two-dimensional hyperintensional semantics. I examine then the virtues unique to the modal expressivist approach here proffered in the setting of the foundations of mathematics, by contrast to competing approaches based upon both the inferentialist approach to concept-individuation and the codification of speech acts via intensional semantics.

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).

Expressivism - the sophisticated contemporary incarnation of the noncognitivist research program of Ayer, Stevenson, and Hare - is no longer the province of metaethicists alone. Its comprehensive view about the nature of both normative language and normative thought has also recently been applied to many topics elsewhere in philosophy - including logic, probability, mental and linguistic content, knowledge, epistemic modals, belief, the a priori, and even quantifiers. Yet the semantic commitments of expressivism are still poorly understood and have (...) not been very far developed. As argued within, expressivists have not yet even managed to solve the "negation problem" - to explain why atomic normative sentences are inconsistent with their negations. As a result, it is far from clear that expressivism even could be true, let alone whether it is. Being For seeks to evaluate the semantic commitments of expressivism, by showing how an expressivist semantics would work, what it can do, and what kind of assumptions would be required, in order for it to do it. Building on a highly general understanding of the basic ideas of expressivism, it argues that expressivists can solve the negation problem - but only in one kind of way. It shows how this insight paves the way for an explanatorily powerful, constructive expressivist semantics, which solves many of what have been taken to be the deepest problems for expressivism. But it also argues that no account with these advantages can be generalized to deal with constructions like tense, modals, or binary quantifiers. Expressivism, the book argues, is coherent and interesting, but false. (shrink)

A core commitment of meta-ethical expressivism is that ordinary descriptive judgements are representational states, while normative judgements are non-representational directive states. Traditionally, this commitment has been understood as a psychological thesis about the nature of normative judgements, as the view that normative judgements consist in certain sorts of conative propositional attitudes. This paper’s aim is to challenge this reading and to show that changing our view on how this commitment is to be understood opens up space for attractive forms (...) of expressivism. The paper argues this by example: by presenting one of the possible expressivist views that can be developed on this reading and by arguing that this view has distinctive advantages over forms of expressivism that endorse the traditional interpretation of expressivism.

What is it for a speech-act to be sincere? A very tempting answer, defended by John Searle and others, is that a speech-act is sincere just in case the speaker has the state of mind it expresses. I argue that we should instead hold that a speech-act is sincere just in case the speaker believes that she has the state of mind she believes it expresses (Sections 1 and 2). Scenarios in which speakers are deluded about their own states of (...) mind play an important role in arguing for this account. In the course of developing this account I also explore how it might make good use of the often neglected distinction between insincerity and mere non-sincerity (Section 2). After defending and developing my positive proposal, I explore its implications for debates over expressivism in meta-ethics (Sections 3 and 4). (shrink)

In the twentieth century, questions of meaning and representation played a central role in the development of pragmatism and analytic philosophy. Present-day neopragmatism, such as Huw Price's “global expressivism,” is often framed in terms of a nonrepresentationalist theory of meaning. While some neopragmatists, such as Robert Brandom, advocate a more local approach, this article argues for taking Price's global expressivism to its next logical step: global pragmatism. Global pragmatism prioritizes the behavior-guiding function of language and redefines representation (...) in operational terms. This operational approach stresses the action and conduct-guiding role of language use, highlights the connection between meaning and action, and addresses issues facing Price's global expressivism.

Expressivism can make space for normative objectivity by treating normative stances as pro or con attitudes that can be correct or incorrect. And it can answer the logical challenges that bedevil it by treating a simple normative assertion not merely as an expression of a normative stance, but as an expression of the endorsement of a proposition that is true if and only if that normative stance is correct. Although this position has superficial similarities to normative realism, it (...) does full justice to the core expressivist thesis that, at bottom, a normative assertion expresses a normative stance rather than a factual belief.

This thesis is about the metaphysics of logic. I argue against a view I refer to as ‘logical realism’. This is the view that the logical constants represent a particular kind of metaphysical structure, which I dub ‘logico-metaphysical structure’. I argue instead for a more metaphysically lightweight view of logic which I dub ‘logical expressivism’. -/- In the first part of this thesis (Chapters I and II) I argue against a number of arguments that Theodore Sider (...) has given for logical realism. In Chapter I, I present an argument of his to the effect that logico-metaphysical structure provides the only good explanation of the semantic determinacy of the logical constants. I argue that other explanations are possible. In Chapter II, I present another argument of his to the effect that logico-metaphysical structure is something that comes along with ontological realism: the view that there is a non-language-relative fact of the matter about what exists. I argue that the connection between logical and ontological realism is not as close as Sider makes it out to be. -/- In the second part of this thesis (Chapters III – V) I set out a positive view of the logical constants that can explain both why their meanings are semantically determinate, and why they form part of our vocabulary. On that view, the primary bearers of logical structure are propositional attitudes, and the logical constants are in our language as vehicles for the expression of logically complex propositional attitudes. In Chapter III, I set out an expressivist theory of propositional logic. In Chapter IV, I use this theory to explain how the logical connectives end up having determinate meanings. In Chapter V, I extend the expressivist theory to predicate logic. (shrink)

Expressivism promises an illuminating account of the nature of normative judgment. But worries about the details of expressivist semantics have led many to doubt whether expressivism's putative advantages can be secured. Drawing on insights from linguistic semantics and decision theory, I develop a novel framework for implementing an expressivist semantics that I call ordering expressivism. I argue that by systematically interpreting the orderings that figure in analyses of normative terms in terms of the basic practical attitude of (...) conditional weak preference, the expressivist can explain the semantic properties of normative sentences in terms of the logical properties of that attitude. Expressivism's problems with capturing the logical relations among normative sentences can be reduced to the familiar, more tractable problem of explaining certain coherence constraints on preferences. Particular attention is given to the interpretation of wide-scope negation. The proposed solution is also extended to other types of embedded contexts—most notably, disjunctions. (shrink)

Carnap was one of the first to use the term 'non-cognitivism'. His linguistic pluralism and voluntarism, and his deflationary views of ontology and semantics, are highly congenial to those of us who want to take non-cognitivism in the direction of global expressivism. In his own case, however, this move is in tension with his continued endorsement of what he calls 'the general thesis of logical empiricism', that 'there is no third kind of knowledge besides empirical and logical (...) knowledge.’ So while Carnap clears a path towards global expressivism, he doesn't seem to appreciate what it requires him to leave behind.

In this paper I will develop a view about the semantics of imperatives, which I term Modal Noncognitivism, on which imperatives might be said to have truth conditions (dispositionally, anyway), but on which it does not make sense to see them as expressing propositions (hence does not make sense to ascribe to them truth or falsity). This view stands against “Cognitivist” accounts of the semantics of imperatives, on which imperatives are claimed to express propositions, which are then enlisted in explanations (...) of the relevant logico-semantic phenomena. It also stands against the major competitors to Cognitivist accounts—all of which are non-truth-conditional and, as a result, fail to provide satisfying explanations of the fundamental semantic characteristics of imperatives (or so I argue). The view of imperatives I defend here improves on various treatments of imperatives on the market in giving an empirically and theoretically adequate account of their semantics and logic. It yields explanations of a wide range of semantic and logical phenomena about imperatives—explanations that are, I argue, at least as satisfying as the sorts of explanations of semantic and logical phenomena familiar from truth-conditional semantics. But it accomplishes this while defending the notion—which is, I argue, substantially correct—that imperatives could not have propositions, or truth conditions, as their meanings. (shrink)

The need to distinguish between logical and extra-logical varieties of inference, entailment, validity, and consistency has played a prominent role in meta-ethical debates between expressivists and descriptivists. But, to date, the importance that matters of logical form play in these distinctions has been overlooked. That’s a mistake given the foundational place that logical form plays in our understanding of the difference between the logical and the extra-logical. This essay argues that descriptivists are better positioned (...) than their expressivist rivals to provide the needed account of logical form, and so better able to capture the needed distinctions. This finding is significant for several reasons: First, it provides a new argument against expressivism. Second, it reveals that descriptivists can make use of this new argument only if they are willing to take a controversial—but plausible—stand on claims about the nature and foundations of logic.

Critical psychiatry has recently echoed Szasz’s longstanding concerns about medical understandings of mental distress. According to Szaszianism, the analogy between mental and somatic disorders is illegitimate because the former presuppose psychosocial and ethical norms, whereas the latter merely involve deviations from natural ones. So-called “having-it-both-ways” views have contested that social norms and values play a role in _both_ mental and somatic healthcare, thus rejecting that the influence of socio-normative considerations in mental healthcare compromises the analogy between mental and somatic disorders. (...) This paper has two goals. Firstly, I argue that having-it-both-ways views fail to provide a compelling answer to Szasz’s challenge. The reason is that what is essential to Szasz’s argument is not that mental disorder attributions involve value judgements, but that mental attributions _in general_ do. Mental disorders are thus doubly value-laden and, _qua_ mental, only metaphorically possible. To illustrate this, I construe Szasz’s view and Fulford’s having-it-both-ways approach as endorsing two different kinds of expressivism about mental disorders, pointing out their different implications for the analysis of delusions. Secondly, I argue, against Szaszianism, that Szasz’s rejection of the analogy is relatively irrelevant for discussions about the appropriateness of medicalizing mental distress. Specifically, I draw from socio-normative approaches to the psychopathology/social deviance distinction and mad and neurodiversity literature to argue that a) it is still possible to distinguish social deviance from psychopathology once we reject the analogy; and b) that _both_ medicalizing and normalizing attitudes to mental distress can harmfully wrong people from relevant collectives.

As the foundation of our rationality, logic has traditionally been considered fixed, stable and constant. This conception of the discipline has been challenged recently by the plurality of logics and in this book, Pavel Arazim extends the debate to offer a new view of logic as dynamic and without a definite, specific shape. The Problem of Plurality of Logics examines the origins of our standard view of logic alongside Kant's theories, the holistic view, the issue of logic's pragmatic significance and (...) Robert Brandom's logical expressivism. Arazim then draws on proof-theoretical approaches to present a convincing argument for a dynamic version of logical inferentialism, which opens space for a new freedom to modify our own logic. He explores the scope, possibilities and limits of this freedom in order to highlight the future paths logic could take, as a motivation for further research. Marking a departure from logical monism and also from the recent doctrine of logical pluralism in its various forms, this book addresses current debates concerning the expressive role of logic and contributes to a lively area of discussion in analytic philosophy.
