Emphasizing imaginaries as an essential tool in deep understanding of social phenomena, the essays in this volume address socio-anthropological environments; collective dynamics of social integration; mass media metamorphosis; politics legitimation processes; symbolic dimension of economics and material culture; and representation of otherness.

ABSTRACTLinguistic evidence supports the claim that certain, weak rejections are less specific than assertions. On the basis of this evidence, it has been argued that rejected sentences cannot be premisses and conclusions in inferences. We give examples of inferences with weakly rejected sentences as premisses and conclusions. We then propose a logic of weak rejection which accounts for the relevant phenomena and is motivated by principles of coherence in dialogue. We give a semantics for which this logic is sound and (...) complete, show that it axiomatizes the modal logic KD45 and prove that it still derives classical logic on its asserted fragment. Finally, we defend previous logics of strong rejection as being about the linguistically preferred interpretations of weak rejections. (shrink)

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

Åsa Burman has recently introduced the important notion of telic power and differentiated it from deontic power in an attempt to build a bridge between ideal and non-ideal social ontology. We find Burman’s project promising but we argue that more is to be done to make it entirely successful. First, there is a palpable tension between Burman’s claim that telic power can be ontologically independent of deontic power and her examples, which suggests that these forms of power share the same (...) basis. Second, it is not completely clear how telic power helps non-ideal social ontologists explain oppression, since Burman thinks that both forms of power are transparent to social agents. We offer solutions to both problems. First, we question the thesis that telic power can exist without deontic power. Burman contends that this is possible because some social roles involving telic power can exist independently of institutions, which are––in her opinion––the source of deontic power. Against Burman, we suggest that all social roles involve deontic power, whether or not they are institutional. Second, we argue that while the exercise of deontic power requires a mutual recognition of the social roles of the interacting agents and, therefore, an acceptance of the associated norms, the exercise of telic power does not require acceptance of the relevant norms. This is why invoking telic power is useful in explaining how oppression and injustice can arise. Lastly, we suggest that the relation between teleological normativity and telic power has not been fully clarified by Burman and requires a deeper analysis. (shrink)

This paper focuses on whether static images can depict motion. It is natural to say that pictures depicting objects caught in the middle of a dynamic action—such as Henri Cartier-Bresson’s (1932) Behind the Gare St. Lazare—are pictures of movement, but, given that pictures themselves do not move, can we make sense of such an idea? Drawing on results from experimental psychology and cognitive sciences, I show that we can. Psychological studies on implicit motion and representational momentum indicate that motion is (...) really perceived in some static images: our visual system is built in order to detect motion, even where it is only implied, and to anticipate the probable outcomes of others’ actions—even when the ‘others’ are only the subject matters of pictures’. I argue that, consequently, a range of popular depiction theories—perceptualist theories of depiction—can accommodate depicted motion. (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)

We discuss a well-known puzzle about the lexicalization of logical operators in natural language, in particular connectives and quantifiers. Of the many logically possible operators, only few appear in the lexicon of natural languages: the connectives in English, for example, are conjunction _and_, disjunction _or_, and negated disjunction _nor_; the lexical quantifiers are _all, some_ and _no_. The logically possible nand (negated conjunction) and Nall (negated universal) are not expressed by lexical entries in English, nor in any natural language. Moreover, (...) the lexicalized operators are all upward or downward monotone, an observation known as the Monotonicity Universal. We propose a logical explanation of lexical gaps and of the Monotonicity Universal, based on the dynamic behaviour of connectives and quantifiers. We define update potentials for logical operators as procedures to modify the context, under the assumption that an update by \( \phi \) depends on the logical form of \( \phi \) and on the speech act performed: assertion or rejection. We conjecture that the adequacy of update potentials determines the limits of lexicalizability for logical operators in natural language. Finally, we show that on this framework the Monotonicity Universal follows from the logical properties of the updates that correspond to each operator. (shrink)

Reshaping our methodological research tools for adequately capturing injustice and domination has been a central aspiration of feminist philosophy and social epistemology in recent years. There has been an increasingly empirical turn in recent feminist and political theorization, engaging with case studies and the challenges arising from conducting research in solidarity with unequal partners. I argue that these challenges cannot be resolved by merely adopting a norm and stance of deference to those in the struggle for justice. To conduct philosophical (...) research in an engaged and solidaristic manner, I suggest that deference be supplemented by three methodological and normative principles: 1) epistemic humility, 2) accountability, and 3) co-producing knowledge. I situate these principles within contemporary philosophical work on solidarity, and show how they might help confront power imbalances and other methodological hazards that arise when conducting research in solidarity with others. I arrive at these principles in part by critically reflecting on my own attempt to conduct research in solidarity with women’s rights activists in Senegal. (shrink)

In this paper, we develop an impure somatic theory of emotion, according to which emotions are constituted by the integration of bodily perceptions with representations of external objects, events, or states of affairs. We put forward our theory by contrasting it with Prinz's pure somatic theory, according to which emotions are entirely constituted by bodily perceptions. After illustrating Prinz's theory and discussing the evidence in its favor, we show that it is beset by serious problems—i.e., it gets the neural correlates (...) of emotion wrong, it isn't able to distinguish emotions from bodily perceptions that aren't emotions, it cannot account for emotions being directed towards particular objects, and it mischaracterizes emotion phenomenology. We argue that our theory accounts for the empirical evidence considered by Prinz and solves the problems faced by his theory. In particular, we maintain that our theory gives a unified and principled account of the relation between emotions and bodily perceptions, the intentionality of emotions, and emotion phenomenology.

In set theory, a maximality principle is a principle that asserts some maximality property of the universe of sets or some part thereof. Set theorists have formulated a variety of maximality principles in order to settle statements left undecided by current standard set theory. In addition, philosophers of mathematics have explored maximality principles whilst attempting to prove categoricity theorems for set theory or providing criteria for selecting foundational theories. This article reviews recent work concerned with the formulation, investigation and justification (...) of maximality principles. (shrink)

This article investigates Hegel's later theory of perception and cognition, identifying and analysing its general assumptions about the relation among the mind's activities. These often unremarked upon assumptions, I claim, continue to underwrite recent interpretive controversies. I demonstrate how a correct understanding of such assumptions points us toward an alternative interpretation of Hegel's model of the mind. I argue that this new model changes how we understand (a) Hegel's later notion of ‘non-conceptual content’ and (b) his distinction between human and (...) animal minds—two areas that constitute the fault line dividing interpretations of late Hegel. To isolate the relevant assumptions, I use Matthew Boyle's influential conceptual distinction between ‘additive’ and ‘transformative’ models of rationality. I demonstrate that Hegel himself addresses the basic issues characterizing this distinction and clarify how approaching his work in these terms presents considerable interpretative and conceptual advantages, including allowing us to defend the position that Hegel adopts a ‘transformative’ framework of mind. To support this argument, this paper closely analyses Hegel's treatment of sensation (Empfindung), which has not yet been systematically addressed by scholars. I show how sensation can be best understood as part of Hegel's later ‘transformative’ framework for cognition. I also show how this framework can be extended to other parts of Hegel's theory.

This paper investigates Hegel’s account of the animal organism as it is presented in the Philosophy of Nature, with a special focus on its normative implications. I argue that the notion of “organisation” is fundamental to Hegel’s theory of animal normativity. The paper starts by showing how a Hegelian approach takes up the scientific image of organism and assigns a basic explanatory role to the notion of “organisation” in its understanding living beings. Moving from this premise, the paper turns to (...) the group of accounts in contemporary theoretical biology known as “organisational accounts”, which offer a widely debated strategy for naturalizing teleology and normativity in organisms. As recent scholarship recognizes, these accounts explicitly rely on insights from Kant and Post-Kantianism. I make the historical and conceptual argument that Hegel’s view of the organism shares several basic commitments with OAs, especially regarding the notion of “organisational closure”. I assess the account of normativity that such accounts advance and its implications for how we approach Hegel. Finally, I argue that the notion of “organisation” is more fundamental to Hegel’s theory of animal normativity than the Aristotelian notion of “Gattung” or “species”, which by contrast appears derivative – at least in the Philosophy of Nature and the Lectures – and does not play the central role in his account maintained by some scholars.

Constitutivism argues that the source of the categorical force of the norms of rationality and morality lies in the constitutive features of agency. A systematic failure to be guided by these norms would amount to a loss or lack of agency. Since we cannot but be agents, we cannot but be unconditionally guided by these norms. The constitutivist strategy has been challenged by David Enoch. He argues that our participation in agency is optional and thus cannot be a source of (...) categorical demands. In this paper, I defend the viability of constitutivism by showing that agency is indeed a special ‘inescapable’ enterprise. Agency has the largest jurisdiction, and it is closed under rational assessment. This inescapability does not exempt constitutivism from raising the question whether agents have reason to be agents, but this question has to be taken up within agency. If this question is answered affirmatively, then—I argue—the criteria of practical correctness are self-ratifying in a non-circular way. This is sufficient to show the viability of the constitutivist strategy. Whether agents have conclusive reasons to be agents, however, is a matter to be addressed in the terms of particular versions of constitutivism. (shrink)

This chapter discusses the structure of our temporally extended agency. We do not have the power to act directly at a distance, so any of our temporally extended projects must be sustained over its temporal unfolding by momentary actions. We need both the capacity to organize these momentary steps in light of a synoptic overview of the extended activity as a whole and to sustain our motivation to continue to pursue the extended activity. Hence, the distinctive mode in which we (...) act over time is that of ’planning agency,’ which requires a form of temporal identification that goes beyond mere psychological continuity. I then discuss the differences in internal structure between merely continuous and integrated activities, and between telic and atelic ones. I provide a taxonomy of the different kinds of temporal goods and values and how these structures might bear on the risk of crisis of meaning in our temporal existence. I then touch briefly on the issue of how our mortality might make a difference to the structure of what we find valuable and how it relates to the temporal features of our agency. In the closing section, I discuss the effects of the moving temporal location of the agent (with her local executive powers) relative to her extended pursuits, including the asymmetries generated by the distinction between past and future stages of the activity and the moving horizon of what the agent can anticipate and (indirectly) control.

The recurring claim that the construct of psychopathy is value laden often is not qualified in enough detail. The chapters in this part of the volume, instead, investigate in depth the role and significance of values in different aspects of the construct of psychopathy. Following these chapters, but also by offering a background to them, we show how certain values are involved in the characterisation of psychopathy, inform societal needs satisfied by this construct, and have a central role in determining (...) whether psychopathy is a mental disorder. Moreover, we relate this description to our criticism of the view that the entrenchment of the notion of psychopathy with values in principle renders it irreconcilable with sound psychiatric theory and practice. However, we also recognize that the value-ladenness of psychopathy leaves open other important challenges. Meeting them needs addressing interdisciplinary interrelated issues that have empirical, normative, and theoretical dimensions. (shrink)

In this paper we show how Dummett-Prawitz-style proof-theoretic semantics has to be modified in order to cope with paradoxical phenomena. It will turn out that one of its basic tenets has to be given up, namely the definition of the correctness of an inference as validity preservation. As a result, the notions of an argument being valid and of an argument being constituted by correct inference rules will no more coincide. The gap between the two notions is accounted for by (...) introducing the distinction between sense and denotation in the proof-theoretic-semantic setting. (shrink)

Arbitrariness is a distinctive feature of human language, and a growing body of comparative work is investigating its presence in animal communication. But what is arbitrariness, exactly? We propose to distinguish four notions of semiotic arbitrariness: a notion of opaque association between sign forms and semiotic functions, one of sign‐function mapping optionality, one of acquisition‐dependent sign‐function coupling, and one of lack of motivatedness. We characterize these notions, illustrate the benefits of keeping them apart, and describe two reactions to our proposal: (...) abandoning arbitrariness‐talk in favor of the newly introduced conceptual vocabulary, or feeding the distinctions back into the parent concept.

This paper offers an overview of the ways agents might extend over time and the characteristic structure of extended human agency. Agency can extend in two distinct but combinable modes: the ontological, which gives rise to simple continuous agents; and the conceptual, which gives rise to agents who conceive of and care about distal times, and have minimal planning abilities. Our extended form of agency combines both. But we are still limited by the temporal locality in the operation of our (...) psychological and executive powers. To account for this locality, I introduce the notion of 'temporal selves,' as the loci of immediacy in the agent's determination of their psychology, conduct, and practical standpoint. I argue that the passage of time generates, by itself, the threat of temporal alienation from distant temporal selves. A genuinely extended agency requires temporal identification: the sharing, by separate temporal selves, of a temporally extended and integrated practical standpoint. This temporal identification cannot be produced simply by temporal identity as continuity. What is required is temporal identity in the mode of unity and integration. This identity does not precede temporal identification but is co-constituted with it. I offer a preliminary account of the structure of the units of integration for agents who aspire to persist in the mode of unity and integration. I close with a cautionary note: the complex structure of integration, although familiar in everyday life, is often missed by standard philosophical accounts, which tend to focus on simple models of extended agency.

Affective experiences such as pains, pleasures, and emotions have affective phenomenology: they feel pleasant. This type of phenomenology has a loopy regulatory profile: it often motivates us to act a certain way, and these actions typically end up regulating our affective experiences back. For example, the pleasure you get by tasting your morning coffee motivates you to drink more of it, and this in turn results in you obtaining another pleasant gustatory experience. In this article, we argue that reflexive imperativism (...) is the only intentionalist account of affective phenomenology—probably, the only account at all—that is able to make sense of its loopy regulatory profile.

In this paper we focus on two claims, put forward by Feyerabend in his later writings , which constitute the metaphysical core of his view of scientific inquiry. The first, that we call the pliability thesis, is the claim that the world can be described by indefinitely many conceptual systems, none of them enjoying a privileged status. The second, that we call the resistance thesis, is the claim that the pliability of the world is limited, i.e., not all the different (...) conceptual systems that can be used to describe the world will be equally successful: the world offers resistance to some attempts to describe it. We show that, in spite of the later Feyerabend’s notorious antirealist leanings, the pliability thesis is fully compatible with a robustly realist view of science, and we suggest that, surprisingly, Feyerabend’s insights concerning the limited pliability of the world turn out to be those of a potential ally of sophisticated versions of scientific realism.

Maddy gave a semi-formal account of restrictiveness by defining a formal notion based on a class of interpretations and explaining how to handle false positives and false negatives. Recently, Hamkins pointed out some structural issues with Maddy's definition. We look at Maddy's formal definitions from the point of view of an abstract interpretation relation. We consider various candidates for this interpretation relation, including one that is close to Maddy's original notion, but fixes the issues raised by Hamkins. Our work brings (...) to light additional structural issues that we also discuss. (shrink)

Paul Horwich (1990) once suggested restricting the T-Schema to the maximally consistent set of its instances. But Vann McGee (1992) proved that there are multiple incompatible such sets, none of which, given minimal assumptions, is recursively axiomatizable. The analogous view for set theory---that Naïve Comprehension should be restricted according to consistency maxims---has recently been defended by Laurence Goldstein (2006; 2013). It can be traced back to W.V.O. Quine(1951), who held that Naïve Comprehension embodies the only really intuitive conception of set (...) and should be restricted as little as possible. The view might even have been held by Ernst Zermelo (1908), who,according to Penelope Maddy (1988), subscribed to a ‘one step back from disaster’ rule of thumb: if a natural principle leads to contra-diction, the principle should be weakened just enough to block the contradiction. We prove a generalization of McGee’s Theorem, anduse it to show that the situation for set theory is the same as that for truth: there are multiple incompatible sets of instances of Naïve Comprehension, none of which, given minimal assumptions, is recursively axiomatizable. This shows that the view adumbrated by Goldstein, Quine and perhaps Zermelo is untenable. (shrink)

We present a natural deduction system for dual-intuitionistic logic. Its distinctive feature is that it is a single-premise multiple-conclusions system. Its relationships with the natural deduction systems for intuitionistic and classical logic are discussed.

Many authors in the field of Environmental Philosophy have claimed to be inspired by Spinoza's monism, which has traditionally been considered a form of pantheism because nature and God coincide. This idea has deep normative implications, as some environmental ethicists claim that wounding nature is the same as wounding God, which implies a resacralization of nature. In particular, we will focus on Arne Næss's Ecosophy (or Deep Ecology) to offer a current relevant example of the pantheist (or panentheist) worldview. However, (...) a new demarcation distinguishes pantheism from panentheism; in the latter, nature and God belong together but do not fully coincide, as in pantheism. Nevertheless, whether Spinoza is a panentheist, pantheist, or neither has yet to be fully determined, as well as whether his doctrine serves as a proper foundation for an ecology that attempts the aforementioned resacralization of nature. This article attempts to clarify these issues. (shrink)

The aim of this paper is to clarify what kind of normativity characterizes a convention. First, we argue that conventions have normative consequences because they always involve a form of trust and reliance. We contend that it is by reference to a moral principle impinging on these aspects (i.e. the principle of Reliability) that interpersonal obligations and rights originate from conventional regularities. Second, we argue that the system of mutual expectations presupposed by conventions is a source of agreements. Agreements stemming (...) from conventions are “tacit” in the sense that they are implicated by what agents do (or forbear from doing) and without that any communication between them is necessary. To justify this conclusion, we assume that: (1) there is a salient interpretation, in some contexts, of everyone’s silence as confirmatory of the others’ expectations (an epistemic assumption), and (2) the participating agents share a value of not being motivated by hostile attitudes (a motivational assumption). By clarifying the relation between conventions and agreements, the peculiar normativity of conventions is analyzed. (shrink)

In this paper, I discuss whether there are genuinely *diachronic* constraints of practical rationality, that is, pressures on combinations of practical attitudes over time, which are not reducible to mere synchronic rational pressures. Michael Bratman has recently argued that there is at least one such diachronic rational constraint that governs the stability of intentions over time. *Pace* Bratman, I argue that there are no genuinely diachronic constraints on intentions that meet the stringent desiderata set by him. But I show that (...) there are at least two synchronic rational constraints with distinctive and important, although only indirect, diachronic dimensions. Neither of them, however, supports the practical conservatism in the face of normative underdetermination that, according to Bratman, is part and parcel of the diachronic rationality of intention stability.

One way in which we might approach the challenge posed by the Sorites Paradox is considering that Sorites-susceptible predicates have several candidate extensions, or several ways in which these expressions can be made precise. For example, a candidate extension for the predicate ‘is a baby’ is the set of humans of less than two years, but also the set of those less than two years and one second, and of those less than two years and two seconds. In this chapter (...) we present and discuss two theories for vague predicates based on this idea: supervaluationism and subvaluationism. The chapter is structured in three parts. The first presents the super- and subvaluationist theories: their similarities and differences in the semantics, the resulting logics with their most characteristic features. The second reviews the super- and subvaluationist solutions to the Sorites Paradox and provides discussion on several controversies surrounding these theories. The third part introduces proof procedures for s’valuationist logics. (shrink)

Mathematical realists have long invoked the categoricity of axiomatizations of arithmetic and analysis to explain how we manage to fix the intended meaning of their respective vocabulary. Can this strategy be extended to set theory? Although traditional wisdom recommends a negative answer to this question, Vann McGee (1997) has offered a proof that purports to show otherwise. I argue that one of the two key assumptions on which the proof rests deprives McGee's result of the significance he and the realist (...) want to attribute to it. I consider two strategies to deal with the problem --- one of which is outlined by McGee himself (2000) --- and argue that both of them fail. I end with some remarks on the prospects for mathematical realism in the light of my discussion. (shrink)

In this paper, I will discuss the various ways in which intentions can be said to be conditional, with particular attention to the internal conditions on the intentions’ content. I will first consider what it takes to carry out a conditional intention. I will then discuss how the distinctive norms of intention apply to conditional intentions and whether conditional intentions are a weaker sort of commitments than the unconditional ones. This discussion will lead to the idea of what I call (...) the ‘deep structure’ of intentions. Roughly, this is the idea that the conditional nature of our intentions is only partially made explicit in the expressions we use to communicate our intentions and in the explicit form of our thinking about and reasoning with them. Most conditions that qualify our intentions are part of a deep functional structure that can be evinced by observing the actual psychological functioning of intentions and by considering the rational requirements that they engage. I will argue that the deep structure of intentions is characteristically conditional. Genuinely unconditional intentions are only limiting instances of conditional intentions and their contribution to agency can only be understood in light of this fact. I will conclude by showing that the characteristic conditional structure of intentions is intimately related to distinctive features of human agency, especially to its unity over time. (shrink)

Some mental states have valence—they are pleasant or unpleasant. According to imperativism, valence depends on imperative content, while evaluativism tells us that it depends on evaluative content. We argue that if one considers valence’s informational profile, it becomes evident that imperativism is superior to evaluativism. More precisely, we show that if one applies the best available metasemantics to the role played by (un)pleasant mental states in our cognitive economy, then these states turn out to have imperative rather than evaluative content, (...) since: (i) they are much more informative about behaviour than they are about the world; and (ii) they occupy a stage in the information-processing chain that is closer to behaviour production than it is to the uptake of sensory information. This is our metasemantic argument for imperativism. (shrink)

It is often argued that future-directed decisions are effective at shaping our future conduct because they give rise, at the time of action, to a decisive reason to act as originally decided. In this paper, I argue that standard accounts of decision-based reasons are unsatisfactory. For they focus either on tie-breaking scenarios or cases of self-directed distal manipulation. I argue that future-directed decisions are better understood as tools for the non-manipulative, intrapersonal division of deliberative labor over time. A future-directed decision (...) to ϕ gives rise to a defeasible exclusionary reason to ϕ. This reason is grounded on the default authority that is normally granted to one’s prior self as an “expert” deliberator. I argue that this kind of exclusionary reason is the only one that can account for the effectiveness of future-directed decisions at shaping our diachronic agency without violating our autonomy over time. (shrink)

In this paper I investigate whether there are genuine and irreducible pressures of diachronic rationality grounded on the structure of the subject rather than on substantive considerations, such as pragmatic ones. I argue that structural pressures of diachronic rationality have a limited scope. The most important pressure only tells against arbitrary interference with the mechanisms for the retention of attitudes over time. I then argue that in the practical case, a substantial account in terms of the agent's temporal identity appears (...) more promising than a purely structural one, but in the end it still leaves many questions about diachronic practical rationality underdetermined.

Human mental workload is arguably the most invoked multidimensional construct in Human Factors and Ergonomics, getting momentum also in Neuroscience and Neuroergonomics. Uncertainties exist in its characterization, motivating the design and development of computational models, thus recently and actively receiving support from the discipline of Computer Science. However, its role in human performance prediction is assured. This work is aimed at providing a synthesis of the current state of the art in human mental workload assessment through considerations, definitions, measurement techniques (...) as well as applications, Findings suggest that, despite an increasing number of associated research works, a single, reliable and generally applicable framework for mental workload research does not yet appear fully established. One reason for this gap is the existence of a wide swath of operational definitions, built upon different theoretical assumptions which are rarely examined collectively. A second reason is that the three main classes of measures, which are self-report, task performance, and physiological indices, have been used in isolation or in pairs, but more rarely in conjunction all together. Multiple definitions complement each another and we propose a novel inclusive definition of mental workload to support the next generation of empirical-based research. Similarly, by comprehensively employing physiological, task-performance, and self-report measures, more robust assessments of mental workload can be achieved. (shrink)

One type of argument to sceptical paradox proceeds by making a case that a certain kind of metaphysically “heavyweight or “cornerstone” proposition is beyond all possible evidence and hence may not be known or justifiably believed. Crispin Wright has argued that we can concede that our acceptance of these propositions is evidentially risky and still remain rationally entitled to those of our ordinary knowledge claims that are seemingly threatened by that concession. A problem for Wright’s proposal is the so-called Leaching (...) worry: if we are merely rationally entitled to accept the cornerstones without evidence, how can we achieve evidence-based knowledge of the multitude of quotidian propositions that we think we know, which require the cornerstones to be true? This paper presents a rigorous, novel explication of this worry within a Bayesian framework, and offers the Entitlement theorist two distinct responses. (shrink)

In this paper, I offer a descriptive and normative analysis of the requirements for effective transnational solidarity between southern NGOs and their northern partners. Drawing on interviews conducted with staff members of Senegalese women’s rights NGOs and a private international development foundation, I contend that existing theories of feminist transnational solidarity cannot allow us to properly acknowledge the power asymmetries and obstacles to solidarity that these NGOs are facing. After assessing the divisions related to gender interests and limited resources that (...) characterize this NGO-ized development landscape, I develop a partial theory of transnational solidarity that would center power asymmetries in order to address practical and political obstacles to solidarity. I argue that an effective account of transnational solidarity must include a commitment to disrupting global hierarchies of power as well as to building practices of accountability and attentiveness to power structures.

At the most general level, the concept of finitism is typically characterized by saying that finitistic mathematics is that part of mathematics which does not appeal to completed infinite totalities and is endowed with some epistemological property that makes it secure or privileged. This paper argues that this characterization can in fact be sharpened in various ways, giving rise to different conceptions of finitism. The paper investigates these conceptions and shows that they sanction different portions of mathematics as finitistic.

Lexical innovations (e.g., zero-derivations coined on the fly by a speaker) seem to bear semantic content. Yet, such expressions cannot bear semantic content as a function of the conventions of meaning in force in the language, since they are not part of its lexicon. This is in tension with the commonplace view that the semantic content of lexical expressions is constituted by linguistic conventions. The conventionalist has two immediate ways out of the tension. The first is to preserve the conventionalist (...) assumption and deny that lexical innovations bear semantic content. The second is to dynamicize the conventionalist assumption, that is, argue that presentations of unattested expressions trigger an augmentation of the standing semantic resources of the language and instantiate content as a result of this underlying update. Building on a comparison with the production of novel onomatopoeic words, iconic pseudowords and pro-speech gestures, the paper argues that the issue is best addressed by suspending the conventionalist assumption, and describes the metasemantic implications of the claim.

This article criticizes Laura Valentini's criterion for distinguishing good and bad idealizations in normative political theory. I argue that, on an attentive reading of her criterion, all ideal theories she discusses must be written off as incorporating bad idealizations. This fact makes Valentini's criterion trivially implausible, for it is argued that there are good idealizations that succeed in promoting the action-guiding goal of ideal theory. Upon rejecting an attempt to salvage the idealizations that Valentini marks off as bad, I develop (...) an alternative criterion for demarcating good and bad idealizations. The criterion holds that the standing of a theory's idealized assumptions depends on whether the stipulated idealizations can be feasibly realized in the non-ideal world, and thus on whether the principles that the theory generates can be made relevant for real-world practice. I also claim that the feasibility criterion better reflects the function of idealization in promoting action-guidance. Unlike Valentini's criterion, the feasibility criterion yields the result that Rawls' theories of domestic and international justice both incorporate bad idealizations. (shrink)

In the first chapter, we discuss Dummett’s idea that the notion of truth arises from the one of the correctness of an assertion. We argue that, in a first-order language, the need of defining truth in terms of the notion of satisfaction, which is yielded by the presence of quantifiers, is structurally analogous to the need of a notion of truth as distinct from the one of correctness of an assertion. In the light of the analogy between predicates in Frege (...) and open formulas in Tarksi, we concentrate on the semantic status of predicates. We register a dual attitude of Dummett towards Frege’s ascription of reference to predicates. On the one it is needed to endow quantifiers with their appropriate meaning. On the other hand, the introduction of concepts, as semantic correlate of predicates, smuggles a realist flavor in the overall semantic picture. In concluding the excursus (and with it the chapter), we stress Dummett’s will of developing a semantic picture free from this realist trait. In the second chapter, we present the idea of a proof-theoretic semantics. As for Frege true sentences denotes the truth-value True, so here closed' (i.e. categorical) valid argumentations denotes proofs. If a language contains implication-like operators, in order to characterize the condition of validity of a closed argumentation one has to introduce a notion of validity applying to ‘open’ (i.e. hypothetical) argumentations. We argue that this problem is analogous to the one posed by quantifiers in Frege-Tarksi’s style semantics. That is, implication forces one to introduce notion of validity for argumentations, which is more substantial than the correctness of the assertion of their conclusions. As we saw, the corresponding claim in the truth-based approach—that quantifiers require one to introduce a notion of truth, which is more substantial than the one of an assertion being correct—was the source of realism. Hence, Dummett proposes to reduce the semantic contribution of open argumentations to the one of their ‘closed instances’. In the truth-based perspective, this would correspond to the denial of the need of introducing concepts as the semantic correlates of predicates. We argue that Dummett’s fear, that an irreducible notion of function (represented by the need of ascribing validity to open argumentations) would lead to realism, turns out to be ill-founded. In the third chapter, we discuss the role played by the notion of truth in the anti-realist account. The notion of truth is what the anti-realist needs to cope with the so-called paradox of deduction. The analysis of the paradox yields to distinguishing between the truth of a sentence and the truth of a sentence being recognized. In terms of these conceptual couple, we reconsider the relationship between truth and assertion in an anti-realist perspective. Grounds are provided for a thesis (which was already advanced in chapter two), according to which the notion of the assertion of a sentence being correct is primarily connected only with the canonical means of establishing a sentence. The possibility of establishing a sentence by indirect means is conceptually dependent on the practice of establishing logical relationship of dependence among sentences. That is, the notion of a closed valid non-canonical argumentation is of any theoretical relevance only in presence of a notion of validity applying to open argumentations. In the fourth chapter, we discuss the possibility of characterizing in the proof-theoretic-semantics a notion of refutation. We develop an original characterization of refutations starting from an informal inductive specification of the condition of refutations of logically complex sentences. A sub-structural logic, called dual-intuitionistic logic, stands to this notion in the same relationship in which intuitionistic logic stands to the notion of proof so far consdered. All notions developed in chapter 2 have their corresponding (dual) ones in the framework developed. In particular, the distinctions canonical/non-canonical and closed/open argumentations. In the refutation based perspective, elimination rules have priority over introductions and the (only) assumption over the (many) conclusions. In the conclusions, we indicate the ingredients that an anti-realist approach to meaning should incorporate, in order to avoid the difficulties we registered. The core of an alternative view is a different conception of the relationship between categorical and hypothetical notions, in which the validity of open argumentations is not reduced to that of their instances, but rather it is directly defined. As a limit case, one would get a notion of validity applying to closed argumentations. (shrink)

A citizen of Early Renaissance Florence that stepped out into the streets and entered the spaces of his civic world joined a concert of creative formal behaviors in which he was at once an actor and a spectator. His problem here was to interpret the complex web of overlapping, conflicting and simultaneous meanings he would have read in the actions and images by which the community directed him and represented itself, and find his own place and set his standing. On (...) most occasions he would probably have elected for a state of suspension, a floating of multiple possibilities he was loath to precipitate in too stable a form: in ambiguity the citizen of Florence developed a richness of signification, and found a refuge.

We offer a novel picture of mathematical language from the perspective of speech act theory. There are distinct speech acts within mathematics, and, as we intend to show, distinct illocutionary force indicators as well. Even mathematics in its most formalized version cannot do without some such indicators. This goes against a certain orthodoxy both in contemporary philosophy of mathematics and in speech act theory. As we will comment, the recognition of distinct illocutionary acts within logic and mathematics and the incorporation (...) of illocutionary force indicators in the formal language for both goes back to Frege’s conception of these topics. We are, therefore, going back to a Fregean perspective. This paper is part of a larger project of applying contemporary speech act theory to the scientific language of mathematics in order to uncover the varieties and regular combinations of illocutionary acts present in it. For reasons of space, we here concentrate only on assertive and declarative acts within mathematics, leaving the investigation of other kinds of acts for a future occasion. (shrink)
