There are several issues with the standard approach to the relationship between conditionals and assertions, particularly when the antecedent of a conditional is false. One prominent alternative is to say that conditionals do not express propositions, but rather make conditional assertions that may generate categorical assertions of the consequent in certain circumstances. However, this view has consequences that jar with standard interpretations of the relationship between proofs and assertion. Here, I analyse this relationship, and say that, on at least one (...) understanding of proof, conditional assertions may reflect the dynamics of proving, which generate categorical assertions. In particular, when we think about the relationship between assertion and proof as rooted in a dialogical approach to both, the distinction between conditional and categorical assertions is quite natural.

My paper is concerned with the relation between ought-statements and intentions in Wilfrid Sellars’s philosophy. According to an entrenched view in Sellars scholarship, Sellars considers ought-statements as expressions of we-intentions. The aim of my paper is to question this reading and to propose an alternative. According to this alternative reading of Sellars, ought-statements are metalinguistic statements about the implication relations between intentions. I show that the entrenched understanding faces many unacknowledged problems and generates incompatibilities with Sellars’s commitments about intentions. I (...) argue that the alternative account can help to resolve these problems. A second reason in support of the alternative understanding of Sellars is provided by historical considerations. I argue that my alternative account can be discerned in Sellars’s most developed views about intentions and ought-statements. I also discuss problems and questions which the alternative reading itself faces. (shrink)

Alvin Plantinga's evolutionary argument against naturalism makes the case that the conjunction of evolutionary theory and naturalism cannot be rationally believed, as, if both evolutionary theory and naturalism were true, it would be highly unlikely that our cognitive faculties are reliable. I present Plantinga's evolutionary argument against naturalism and survey a theory of meaning espoused by Robert Brandom, known as semantic inferentialism. I argue that if one accepts semantic inferentialism, as it is developed by Brandom, then Plantinga's motivation for the (...) evolutionary argument against naturalism is undermined. (shrink)

Imagine you’re teaching someone how to play chess. You might start by saying ‘White must move first’, where the word ‘must’ is used to convey a rule. You would.

Robert Brandom holds that what we mean is best understood in terms of what inferences we are prepared to defend, and that such a defence is best understood in terms of rule-governed social interactions. This manages to explain quite a lot. However, for those who think that there is more to making correct/incorrect inferences than obeying/breaking accepted rules, Brandom’s account fails to adequately capture what it means to reason properly. Thus, in an effort to sketch an alternative that does not (...) rely primarily on peer pressure, I draw on the work of C. S. Peirce. Peirce argued that, when we reason, we manipulate abstract diagrams in order to observe what results. Since some manipulations are barred by the self-same nature of the diagrams, I try to show that this qualitative incompatibility, which I dub “contrapiction,” is a good reason to regard some reasoning as bad.

I argue that modal epistemology should pay more attention to questions about the structure and function of modal thought. We can treat these questions from synchronic and diachronic angles. From a synchronic perspective, I consider whether a general argument for the epistemic support of modal though can be made on the basis of modal thoughs’s indispensability for what Enoch and Schechter (2008) call rationally required epistemic projects. After formulating the argument, I defend it from various objections. I also examine the (...) possibility of considering the indispensability of modal thought in terms of its components. Finally, I argue that we also need to approach these issues from a diachronic perspective, and I sketch how to approach this task. (shrink)

Several legal arguments use the notion of ratio legis in order to sustain a normative conclusion, in particular the argument from analogy and some forms of teleological argumentation. However, determining the ratio is often a difficult and controversial task. In this paper we look firstly at the speech acts typically performed by legal practitioners in order to determine the ratio and, secondly, we take into account the argumentative commitments they undertake in so doing and the argumentative constraints put on them. (...) This will lead us to distinguish different uses of the notion of ratio legis and to ask on what conditions each of them is justified. (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. (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)

An influential suggestion from David Lewis is that we should think of assertions in terms of how they affect the conversational score. This note outlines a way to model conversational scores in such a way that two assertoric effects are brought together: that to assert is to propose to add information to the common ground, and that to assert is to undertake commitments. Rather than being seen as rivals, they should be viewed as complementary descriptions of our practises of making (...) assertions. (shrink)

We investigate the relations among Brandom’s three dimensions of semantic inferential articulation, namely, incompatibility entailments, committive consequences, and permissive consequences. In his unpublished manuscript “Conceptual Content and Discursive Practice” Brandom argues that (1) incompatibility entailment implies committive consequence, and that (2) committive consequence in turn implies permissive consequence. We criticize this hierarchy both on internal and external grounds. Firstly, we prove that, using Brandom’s own definitions, the reverse of (1) also holds, and that the reverse of (2) may hold (but (...) the proof relies on substantive assumptions). This suggests that there are no three different notions of inference emerging from Brandom’s definitions, but at most two, and perhaps even just one. Secondly, this result puts into question the connections between the three inferential relations and the familiar notions of deduction and induction. (shrink)

This volume seeks to further the use of formal methods in clarifying one of the central problems of philosophy: that of our free human agency and its place in our indeterministic world. It celebrates the important contributions made in this area by Nuel Belnap, American logician and philosopher. Philosophically, indeterminism and free action can seem far apart, but in Belnap’s work, they are intimately linked. This book explores their philosophical interconnectedness through a selection of original research papers that build forth (...) on Belnap’s logical and philosophical work. Some contributions take the form of critical discussions of Belnap's published work, some develop points made in his publications in new directions, and others provide additional insights on the topics of indeterminism and free action. In Nuel Belnap’s work on indeterminism and free action, three formal frameworks figure prominently: the simple branching histories framework known as "branching time;" its relativistic spatio-temporal extension, branching space-times; and the “seeing to it that” logic of agency. As those frameworks provide the formal background for the contributed papers, the volume introduction gives an overview of the current state of their development. It also introduces case-intensional first order logic, a general intensional logic offering resources for a first-order extension of the mentioned frameworks and a recent research focus of Belnap’s. The volume also contains an extended biographical interview with Nuel Belnap. (shrink)

In this paper, I discuss the analysis of logic in the pragmatic approach recently proposed by Brandom. I consider different consequence relations, formalized by classical, intuitionistic and linear logic, and I will argue that the formal theory developed by Brandom, even if provides powerful foundational insights on the relationship between logic and discursive practices, cannot account for important reasoning patterns represented by non-monotonic or resource-sensitive inferences. Then, I will present an incompatibility semantics in the framework of linear logic which allow (...) to refine Brandom’s concept of defeasible inference and to account for those non-monotonic and relevant inferences that are expressible in linear logic. Moreover, I will suggest an interpretation of discursive practices based on an abstract notion of agreement on what counts as a reason which is deeply connected with linear logic semantics. (shrink)

Public deliberation has been defended as a rational and noncoercive way to overcome paradoxical results from democratic voting, by promoting consensus on the available alternatives on the political agenda. Some critics have argued that full consensus is too demanding and inimical to pluralism and have pointed out that single-peakedness, a much less stringent condition, is sufficient to overcome voting paradoxes. According to these accounts, deliberation can induce single-peakedness through the creation of a ‘meta-agreement’, that is, agreement on the dimension according (...) to which the issues at stake are ‘conceptualized’. We argue here that once all the conditions needed for deliberation to bring about single-peakedness through meta-agreement are unpacked and made explicit, meta-agreement turns out to be a highly demanding condition, and one that is very inhospitable to pluralism.

Without directly addressing the Demarcation Problem for logic—the problem of distinguishing logical vocabulary from others—we focus on distinctive aspects of logical vocabulary in pursuit of a second goal in the philosophy of logic, namely, proposing criteria for the justification of logical rules. Our preferred approach has three components. Two of these are effectively Belnap’s, but with a twist. We agree with Belnap’s response to Prior’s challenge to inferentialist characterisations of the meanings of logical constants. Belnap argued that for a logical (...) constant to exist, its rules must be conservative over a previously given consequence relation and guarantee the uniqueness of the constant. The twist is that we require logical vocabulary to be provably conservative, not over a previously given formal consequence relation, but over a previously given meaningful vocabulary of a language. Uniqueness is also a feature defined in terms of provability: if two syntactically distinguished expressions are governed by the same rules, then formulas with them as main operators are interderivable. Belnap’s criteria are not only those for the existence of a logical constant, but more: they are what distinguishes logical vocabulary from all other expressions. It is the defining mark of a logical constant that it is provably conservative over the fragment of the language which excludes it and that its rules guarantee its uniqueness. The third component is the topic neutrality of logic. The provable conservativeness of logic over a previously given vocabulary of a language is motivated, in part, by appeal to molecularism in the theory of meaning. Molecularity is a feature endorsed by the theory of meaning as a whole, so it does not distinguish logical constants from other expressions. The same is true for conservativeness. We argue that molecularity, and hence conservativeness, are implicit presuppositions of speakers’ use of language: the addition of new vocabulary to a language is presupposed to be conservative. But this presupposition is one that we should be able reflectively to endorse (such as when attempting a rational reconstruction of the use of the vocabulary). Thus, where conservativeness is found to fail, this defect should be remedied and the use of the vocabulary corrected (as in classical negation) or excised altogether (as in pejoratives). We go on to characterise a notion of topic neutrality, which we argue applies to logical vocabulary. We then note that reflective endorsement of the conservativeness of a topic neutral vocabulary requires a proof that the vocabulary is conservative relative to any base vocabulary. Thus we require that logical vocabulary be demonstrably conservative. Allying this requirement, distinctive of logic, to a general consideration about the commitments of assertion yields a mode of justification for logical constants akin to some conceptions of Harmony, i.e., to the idea that the consequences of assertion of a logical complex need to be warranted by the grounds and ought to be the strongest consequences warranted by the grounds. Intuitionistic logic acquires a somewhat familiar justification but emanating from a new motivation. (shrink)

This essay attempts to extend the exercise in normative pragmatics undertaken by Robert Brandom to include consideration of the logical relations between the practices of making of claims involving the use of the first-person-singular pronoun (‘I-talk’) and the making of claims involving the second-person-singular pronoun (‘You-talk’). The first part of the essay makes the case that the implicit response found in Brandom’s work affirms the pragmatic independence of I-talk from You-talk, such that it is possible to conceive of a discursive (...) practice involving people using the first person-singular pronoun but not the second-person. The second part argues this response is mistaken, as there are reasons internal to Brandom’s own project that require pragmatic interdependence of I-talk and You-talk. The upshot of this exercise is normative pragmatics is thus that there can be no ‘I’ without a ‘You’. (shrink)

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

Overview of Wilfrid Sellars's philosophy.

Motivated by semantic inferentialism and logical expressivism proposed by Robert Brandom, in this paper, I submit a nonmonotonic modal relevant sequent calculus equipped with special operators, □ and R. The base level of this calculus consists of two different types of atomic axioms: material and relevant. The material base contains, along with all the flat atomic sequents (e.g., Γ0, p |~0 p), some non-flat, defeasible atomic sequents (e.g., Γ0, p |~0 q); whereas the relevant base consists of the local region (...) of such a material base that is sensitive to relevance. The rules of the calculus uniquely and conservatively extend these two types of nonmonotonic bases into logically complex material/relevant consequence relations and incoherence properties, while preserving Containment in the material base and Reflexivity in the relevant base. The material extension is supra-intuitionistic, whereas the relevant extension is stronger than a logic slightly weaker than R. The relevant extension also avoids the fallacies of relevance. Although the extended material consequence relation is defeasible and insensitive to relevance, it has local regions of indefeasibility and relevance (the latter of which is marked by the relevant extension). The newly introduced operators, □ and R, codify these local regions within the same extended material consequence relation. (shrink)

The notion of conceptual normativity is grounded on the idea that our conceptual contents are established by the norms of the discursive social practices we engage in. This idea involves two major problems. First, where do the norms of discursive practices come from and how can the contents that they establish be objective? Second, what is the role of the vocabulary that we use to express such norms as explicit rules? This article draws the outline of an account that could (...) possibly answer both questions. First, it explores the viability of a naturalism about conceptual normativity. Second, it defines the characters of a rational expressivist analysis of the language of the rules. (shrink)

Our purpose in this paper is to contribute to a practice-based characterization of scientific inference. We want to explore whether Brandom’s pragmatist–inferentialist framework can suitably accommodate several types of ampliative inference common in scientific reasoning and explanation (probabilistic reasoning, abduction and idealisation). First, we argue that Brandom’s view of induction in terms of merely permissive inferences is inadequate; in order to overcome the shortcoming of Brandom’s proposal, we put forward an alternative conception of inductive, probabilistic reasoning by appeal to the (...) notion of degrees of commitment. Moreover, we examine the sorts of inferential commitments operative in other types of ampliative inferences, such as abduction or reasoning involving idealizations and assumptions. We suggest that agents engaging in these forms of reasoning often undertake restricted inferential commitments, whose scope and reach are more limited that in the case of the commitments associated with full beliefs.

Although seldom examined and not explained by Robert Brandom himself, the concept of responsibility is as important as the concept of inference for Brandom’s account of discursivity. Whereas ‘inference’ makes explicit the propositional content of concepts as the inferentially structured totality of their relations of material incompatibility, ‘responsibility’ makes explicit the normative force of these relations. ‘Responsibility’ thus becomes the paradigm of understanding normativity’s binding force – and my critical reading demonstrates that it fosters a moralizing, juridifying and economizing understanding (...) of normativity’s binding force. Furthermore, a diagnostic interpretation of Nietzsche’s genealogy of ‘responsibility’ reveals that Brandom’s concept of ‘responsibility’ is not an exception but exemplary for how ‘responsibility’ is used in philosophy.

Normality, for Husserl, is said in many ways. While the most detailed treatments of this technical Husserlian concept are usually found in discussions concerning the constitutive dimension of the lived body and intersubjectivity, little attention has been paid to the notion of normality understood as the tacit regularity of nature. Indeed, the normal can also be understood as the causal background which is presupposed, tentatively, in the anticipation of uniform processes of change, as well as in poieticinstrumental experiences, that is, (...) in experiences involving the production and use of objects. The subject that elaborates, manipulates or uses objects is installed in nature. Hence, in our productive-instrumental confrontation with objects in the world, we operate under the assumption that the potentially mutable causal scene surrounding our acting life will retain its style. This assumption of normality is the world, in one of the many ways in which Husserl characterizes this concept. The world qua background of normality becomes thematic, retrospectively, precisely when it ceases to cooperate with the agent’s initiatives. This, on my view, is what lies behind Husserl’s assertion that the world is a “super-object” or “higher-level theme”. (shrink)

A naturalistic theory of intentionality is proposed that differs from previous evolutionary and tracking theories. Full-blown intentionality is constructed through a series of evolvable refinements. A first, minimal version of intentionality originates from a conjectured internal process that estimates an organism’s own fitness and that continually modifies the organism. This process produces the directedness of intentionality. The internal estimator can be parsed into intentional components that point to components of the process that produces fitness. It is argued that such intentional (...) components can point to mistaken or non-existing entities. Different Fregian senses of the same reference correspond to different components that have different roles in the estimator. Intentional components that point to intentional components in other organisms produce directedness towards semi-abstract entities. Finally, adding a general, population-wide means of communication enables intentional components that point to fully abstract entities. Intentionality thus naturalized has all of its expected properties: being directed; potentially making errors; possibly pointing to non-existent, abstract, or rigid entities; capable of pointing many-to-one and one-to-many; distinguishing sense and reference; having perspective and grain; and having determinate content. Several examples, such as ‘swampman’ and ‘brain-in-a-vat’, illustrate how the theory can be applied. (shrink)

According to recent suggestions within the global pragmatism discussion, metaethical debate must be fundamentally re-framed. Instead of carving out metaethical differences in representational terms, it has been argued that metaethics should be given an inferentialist footing. In this paper, I put inferentialist metaethics to the test by subjecting it to the following two criteria for success: Inferentialist metaethicists must be able to save the metaethical differences between moral realism and expressivism, and do so in a way that employs understandings of (...) these metaethical accounts which would be acceptable to moral realists or expressivists who endorse an inferentialist theory of meaning. Two results follow from my discussion. The first concerns inferentialist metaethics more narrowly, casting doubts on inferentialists’ ability to fulfil the two criteria for success by showing that proposed metaethical demarcation attempts either meet the first criterion but violate the second, or pass the second criterion but fail the first. The second upshot pertains to the global pragmatism debate more widely, pressing the point that inferentialists have not as yet provided a convincing account of ontological commitment. (shrink)

Modality presents notorious philosophical problems, including the epistemic problem of how we could come to know modal facts and metaphysical problems about how to place modal facts in the natural world. These problems arise from thinking of modal claims as attempts to describe modal features of this world that explain what makes them true. Here I propose a different view of modal discourse in which talk about what is “metaphysically necessary” does not aim to describe modal features of the world, (...) but, rather, provides a particularly useful way of expressing constitutive semantic and conceptual rules in the object language. The result is a “modal normativist” view that enables us to avoid the epistemic problems of modality and mitigate the metaphysical worries, while also leaving open the possibility of a unified account of the function of modal language. Finally, I address a serious challenge: we have the norms we do in order to track the modal facts of the world, so that the order of explanation must go in the opposite direction. I close by showing how the normativist may answer that challenge. (shrink)

Those who aim to give an account of modal knowledge face two challenges: the integration challenge of reconciling an account of what is involved in knowing modal truths with a plausible story about how we can come to know them, and the reliability challenge of giving a plausible account of how we could have evolved a reliable capacity to acquire modal knowledge. I argue that recent counterfactual and dispositional accounts of modal knowledge cannot solve these problems regarding specifically metaphysical modal (...) truths—leaving us with the threat of skepticism about large portions of metaphysics, and certain other areas of philosophy. I argue, however, that both of these problems look insuperable only if we assume that metaphysical modal discourse serves a describing or tracking function. If we adopt instead a normativist approach to metaphysical modal discourse, which sees the basic function of modal discourse as giving us perspicuous ways of conveying, reasoning with, and renegotiating semantic rules, the problems show up very differently. The modal normativist can give a plausible response to both of the classic problems of how we can come to know metaphysical modal truths. (shrink)

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

Although Brandom is critical of some features of narrowly conceived classical pragmatism, at the same time he explicitly embraces a version of pragmatism, both in his overall philosophical outlook, and in his philosophy of language. Brandom’s distinctive theoretical approach is based on what he calls rationalist pragmatism, which is a version of fundamental pragmatism. Within the philosophy of language it takes the form of semantic pragmatism. The paper briefly discusses Brandomian version of fundamental pragmatism and its semantic underpinning, and subsequently (...) formulates a basic dilemma it encounters there. (shrink)

Many philosophers working today on the normativity of language have concluded that linguistic activity is not a matter of rule following. These conversations have been framed by a conception of linguistic normativity with roots in Wittgenstein and Kripke. In this paper I use conceptual resources developed by the classical American pragmatists and their descendants to argue that punctate linguistic acts are governed by rules in a sense that has been neglected in the recent literature on the normativity of language. In (...) the course of arguing for this conclusion I defend a Kantian conception of rationality as rule-obeying activity, and I argue that this conception is compatible with a naturalistic understanding of ourselves as rational beings governed by rules of thought and action. (shrink)

How should we understand validity? A standard way to characterize validity is in terms of the preservation of truth (or truth in a model). But there are several problems facing such characterizations. An alternative approach is to characterize validity epistemically, for instance in terms of the preservation of an epistemic status. In this paper, I raise a problem for such views. First, I argue that if the relevant epistemic status is factive, such as being in a position to know or (...) having conclusive evidence for, then the account runs into trouble if we endorse certain familiar logical principles. Second, I argue that if the relevant epistemic status is non-factive, such as is rationally committed to or has justification for believing, then a similar problem arises if we endorse the logical principles as well as a sufficiently strong epistemic “level-bridging” principle. Finally, I argue that an analogous problem arises for the most natural characterization of validity in terms of rational credence. (shrink)

According to the Adoption Problem certain basic logical principles cannot be adopted. Drawing on the AP, Suki Finn presents an argument against logical pluralism: Modus Ponens and Universal Instantiation both govern a general structure shared by every logical rule. As such, analogues of these two rules must be present in every meta-logic for any logical system L, effectively imposing a restriction to logical pluralism at the meta-level through their presence constituting a “meta-logical monism”. We find a tension in the dual (...) role that the “unadoptable rules” must play in Finn’s “meta-logical monism” rendering it ineffective to restrict logical theories and systems. Consequently, we argue they cannot be both analogues of MP and UI and inferentially productive. We conclude with a series of suggestions regarding where a more satisfying and robust interpretation of the AP could lie. (shrink)

Analytic pragmatism is a framework of analysis elaborated by Robert Brandom, whose goal is to explain the relations between meaning and use according to a systematic and general method of inquiry. In April 2009, a workshop was organized to discuss the recent developments of this new theoretical approach. Brandom delivered three lectures, where he explored some aspects of analytic pragmatism and addressed the motivating themes of this enterprise, while the contribution from the other speakers ranged over specific aspects of the (...) theory. This special issue is the outcome of that workshop. In this introduction we briefly outline the context of the debate and present the contribution to this issue selected from a much wider range of papers, using the reviewing process of Philosophia.

A possible way out to Kripke’s Puzzle About Belief could start from the rejection of the notion of epistemic transparency. Epistemic transparency seems, indeed, irremediably incompatible with an externalist conception of mental content. However, Brandom’s inferentialism could be considered a version of externalism that allows, at least in some cases, to save the principle of transparency. Appealing to a normative account of the content of our beliefs, from the inferentialist’s standpoint, it is possible to state that a content is transparent (...) when name-components of that content are a priori associated with some application conditions and, at the same time, reflection alone provides an a priori access to those application conditions, with no need of any empirical investigation. Nevertheless, such requirements are only met in trivial cases. The aim of this paper is to argue that some application conditions of that sort, albeit trivial, can be ontologically ampliative. As a result, the related contents can be regarded as transparent in a substantial and rich way. (shrink)

In his recent John Locke Lectures – published as Between Saying and Doing – Brandom extends and refines his views on the nature of language and philosophy by developing a position that he calls Analytic Pragmatism. Although Brandom’s project bears on an extraordinarily rich array of different philosophical issues, we focus here on the contention that certain vocabularies have a privileged status within our linguistic practices, and that when adequately understood, the practices in which these vocabularies figure can help furnish (...) us with an account of semantic intentionality. Brandom’s claim is that such vocabularies are privileged because they are a species of what he calls universal LX vocabulary –roughly, vocabulary whose mastery is implicit in any linguistic practice whatsoever. We show that, contrary to Brandom’s claim, logical vocabulary per se fails to satisfy the conditions that must be met for something to count as universal LX vocabulary. Further, we show that exactly analogous considerations undermine his claim that modal vocabulary is universal LX. If our arguments are sound, then, contrary to what Brandom maintains, intentionality cannot be explicated as a “pragmatically mediated semantic phenomenon”, at any rate not of the sort that he proposes.

The paper investigates the epistemological and communicative competences the experts need to use and communicate evidence in the reasoning process leading to diagnosis. The diagnosis and diagnosis communication are presented as intertwined processes that should be jointly addressed in medical consultations, to empower patients’ compliance in illness management. The paper presents defeasible reasoning as specific to the diagnostic praxis, showing how this type of reasoning threatens effective diagnosis communication and entails that we should understand diagnostic evidence as defeasible as well. (...) It argues that metaphors might be effective communicative devices to let the patients understand the relevant defeasors in the diagnostic reasoning process, helping to improve effective diagnosis communication, and also encouraging a change in patients’ beliefs and attitudes on their own experience of illness and illness’ management.

Discursive pluralism, recently fostered by anti-representationalist views, by stating that not all assertions conform to a descriptive model of language, poses an interesting challenge to representationalism. Although in recent years alethic pluralism has become more and more popular as an interesting way out for this issue, the discussion also hosts other interesting minority approaches in the anti-representationalist camp. In particular, the late stage of contemporary expressivism offers a few relevant insights, going from Price's denunciation of “placement problems” to Brandom's inferentialism. (...) This paper attempts to show how these expressivist ideas combine well together, composing a unitary and metaphysically sober metaphilosophical framework. (shrink)

We present an inferentialist account of collective rationality and intentionality, according to which beliefs and other intentional states are understood in terms of the normative statuses attributed to, and undertaken by, the participants of a discursive practice—namely, their discursive or practical commitments and entitlements. Although these statuses are instituted by the performances and attitudes of the agents, they are not identified with any physical or psychological entity, process or relation. Therefore, we argue that inferentialism allows us to talk of collective (...) intentionality and agency without needing to posit the existence of any sort of collective psychology or mind. (shrink)

Experience, it is widely agreed, constrains our thinking and is also thoroughly theory-laden. But how can it constrain our thinking while depending on what it purports to constrain? To address this issue, I revisit and carefully analyze the account of observation provided by Norwood Russell Hanson, who introduced the term ‘theory-ladenness of observation’ in the first place. I show that Hanson’s account provides an original and coherent response to the initial question and argue that, if suitably developed, his account provides (...) a distinctive, powerful, and attractive alternative to relationalist and standard representationalist conceptions of experience.

In his program of analytic pragmatism, Robert Brandom has presented a thoroughgoing reinterpretation of the place of analytic philosophy in the history of philosophy by linking his own non-representational ‘inferentialist’ approach to semantics to the rationalist – idealist tradition, and in particular, to Hegel. Brandom, however, has not been without his critics in regard to both his approach to semantics and his interpretation of Hegel. Here I single out four interlinked problematic areas facing Brandom's inferentialist semantics – his approach of (...) perceptual content, to de re attitudes, to perceptual experience and to modality, and then go on to contrast the different approach to these issues that is found in Hegel. While Hegel can helpfully be understood as anticipating an inferentialist semantics as Brandom claims, his is a weak inferentialism in contrast to Brandom's strong version. With his weakly inferentialist approach Hegel can, I suggest, be seen as providing a solution to the tangle of problems.. (shrink)

Reviews Brian Bruya's edited collection The Philosophical Challenge from China.

In this paper, I propose a new way to distinguish between indexicals, like “I” and “today”, and demonstratives, like “she” and “this”. The main test case is the second person singular pronoun “you”. The tradition would generally count it as a demonstrative, because the speaker’s intentions play a role in providing it with a semantic value. I present cross-linguistic data and explanations offered of the data in typology and semantics to show that “you” belongs on the indexical side, and argue (...) that they can be generalized to a novel criterion for distinguishing between indexicals and demonstratives. The central theoretical claim is that the semantic values of indexicals are objects which play certain utterance-related roles, which are fixed independently of the words being used in the utterance. For instance, the speaker plays the speaker role whether or not she uses the word “I”, and the addressee plays that role whether or not the speaker uses the word “you”. Demonstratives, on the other hand, pick out objects that play no such role, and are instead helped by the speaker’s word-specific intentions. (shrink)

In Between Saying and Doing: Towards an Analytic Pragmatism , Robert B. Brandom puts forward a general method of formally representing relations between meaning and use (between vocabularies and practices-or-abilities) and shows how discursive intentionality can be understood as a pragmatically mediated semantic relation. In this context, the activity that pragmatically mediates the semantic relations characteristic of discursive intentionality is specified as a practice of discursive updating —a practice of rectifying commitments and removing incompatibilities. The aim of the paper is (...) to take a closer look at the practice of discursive updating and to show that the role of inconsistencies and disagreements in discursive practice can only be fully understood if the interactional dimension of updating processes is taken into account—i.e. if one looks at the explicitly social, interactional role of discursive updating in cases of disagreements between different subjects.

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 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)

Formal semantics is an enterprise which accounts for meaning in formal, mathematical terms, in the expectation of providing a helpful explication1 of the concept of the meaning of specific word kinds (such as logical ones), or of words and expressions generally. Its roots go back to Frege, who proposed exempting concepts, meanings of predicative expressions, from the legislation of psychology and relocating them under that of mathematics. This started a spectacular enterprise, fostered at first within formal logic and later moving (...) into the realm of natural languages, and featuring a series of eminent scholars, from Tarski and Carnap to Montague and David Lewis. Partly independently of this, Frege set the agenda for a long-term discussion of the question of what a natural language is, his own contribution being that language should be seen not as a matter of subjective psychology, but rather as a reality objective in the sense in which mathematics is objective. His formal semantics, then, was just an expression of this conception of language. And many theoreticians now take it for granted that formal semantics is inseparably connected with a Platonist conception of language. Moreover, the more recent champions of formal semantics, Montague and David Lewis, took for granted that natural language is nothing else than a structure of the very kind envisaged by the theories of formal logicians. While Montague claims quite plainly that there is no substantial difference between formal and natural languages ("I reject the contention," he says, 1974, p. 188, "that an important theoretical difference exists between formal and natural languages"), Lewis states that it is fully correct to say that a linguistic community entertains a language in the form of a mathematical structure ("we can say", states Lewis, 1975, p..

This article suggests reasons why Donald Davidson’s work in philosophy of mind and metaphysics can be identified as Spinozist and also explores the significance of using proper names from the history of philosophy to describe contemporary projects. It argues that what makes Davidson’s work Spinozist is not just its internal features, but the role it occupies in relation to other positions identified as Kantian and Hegelian in today’s philosophical terrain. Finally, it suggests that the core animus at the heart of (...) Davidson’s Spinozism is its indifference to autonomy as a concept in need of metaphysical grounding or essential to normative commitment. (shrink)
