In the present paper we address the old question of respiratory planning in speech production. We recast the problem in terms of speakers’ communicative goals and propose that speakers try to minimise respiratory effort in line with H&H theory. We analyze respiratory cycles coinciding with no speech (i.e. silence), short verbal feedback expressions (SFE’s) as well as longer vocalisations in terms of parameters of the respiratory cycle and find little evidence for respiratory planning in feedback production. We also investigate timing (...) of speech and SFEs in the exhalation and contrast it with nods. We find that while speech is strongly tied to the exhalation onset, SFEs are distributed much more uniformly throughout the exhalation and are often produced on residual air. Given that nods, which do not have any respiratory constraints, tend to be more frequent towards the end of an exhalation, we propose a mechanism whereby respiratory patterns are determined by the trade-off between speakers’ communicative goals and respiratory constraints.

This work revisits the problem of breathing cues used for management of speaking turns in multiparty casual conversation. We propose a new categorisation of turn-taking events which combines the criterion of speaker change with whether the original speaker inhales before producing the next talkspurt. We demonstrate that the latter criterion provides a good proxy for pragmatic completeness of the previous utterance (and, by extension, of the interruptive character of the incoming speech). We also present evidence that breath holds are used (...) in reaction to incoming talk rather than as a turn-holding cue. In addition to analysing dimensions which are routinely omitted in studies of interactional functions of breathing (exhalations, presence of overlapping speech, breath holds), the present study also looks at patterns of breath holds in silent breathing and shows that breath holds are sometimes produced towards the beginning (and towards the top) of silent exhalations, potentially indicating an abandoned intention to take the turn. We claim that the breathing signal can thus be successfully used for uncovering \emph{hidden} turn-taking events, which are otherwise obscured by silence-based representations of interaction.

Abstract: Nietzsche’s famously wrote that “consciousness is a surface” (EH, Why I am so clever, 9: 97). The aim of this paper is to make sense of this quite puzzling contention—Superficiality, for short. In doing this, I shall focus on two further claims—both to be found in Gay Science 354—which I take to substantiate Nietzsche’s endorsement of Superficiality. The first claim is that consciousness is superfluous—which I call the “superfluousness claim” (SC). The second claim is that consciousness is the source (...) of some deep falsification—which I call the “falsification claim” (FC). I shall start by considering Nietzsche’s notion of consciousness. Here, I shall argue that the kind of consciousness he is concerned with is in fact self-consciousness and that he put forward a higher-order theory of it. Then, I shall address the two claims. Regarding (FC), my proposal will be that, according to Nietzsche, the content of (self-)conscious mental states is falsified in virtue of its being articulated propositionally. Regarding (SC), I shall claim that it is best read as a weak version of epiphenomenalism about conscious causation. In addressing both points, I shall discuss in particular the influential reading of Nietzsche’s theory of consciousness offered by Katsafanas (2005). (shrink)

Many theories of rational action are predicated on the idea that what it is rational to do in a given situation depends, in part, on what it is rational to believe in that situation. In short: they treat epistemic rationality as explanatorily prior to practical rationality. If they are right in doing so, it follows, on pain of explanatory circularity, that epistemic rationality cannot itself be a form of practical rationality. Yet, many epistemologists have defended just such a view of (...) epistemic rationality. According to them, there is no such thing as a distinctively epistemic form of rationality which could be explanatorily prior to practical rationality. Rather, they maintain, there is just one form of rationality—practical rationality—of which epistemic rationality is a species. What to make of this conflict? The aim of this paper is to motivate a view about the relationship between epistemic and practical rationality which resolves the conflict in a way that should be attractive to both sides. The central idea is to ground both epistemic and practical rationality in an independently motivated notion of evidential probability which is itself to be understood in non-normative terms. Doing so, I argue, allows us to unify epistemic and practical rationality in a way that does justice to the idea that what it is rational to do depends, in part, on what it is rational to believe; and to do so in a way that avoids explanatory circularity.

Nietzsche vs. Kant? Der siebzehnte Aphorismus aus dem ersten Teil von Menschliches, Allzumenschliches schliesst mit der korrosiven Bemerkung, das Ding an sich [sei] eines homerischen Gelachters werth. Aufgrund dieser Passage nun aber zu vermuten, Nietzsche habe diesen von Kant stammenden Terminus einfach so ad acta gelegt, ware jedoch ubereilt, denn die Auseinandersetzung mit der Unterscheidung zwischen Erscheinung und Ding an sich lasst sich als Konstante durch Nietzsches gesamtes Werk verfolgen. Mattia Riccardi widmet sich in seiner Studie den verschiedenen Positionen, die (...) Nietzsche im Zusammenhang mit dieser Problematik eingenommen hat: von der im Hintergrund der Geburt der Tragodie prasenten Artisten-Metaphysik bis zur radikalen Infragestellung des kantischen Denkmusters in den Jahren nach 1880. Riccardi beschrankt sich aber nicht auf eine historisch akkurate, direkte und indirekte Textquelle mit einbeziehender Rekonstruktion von Nietzsches kampferischer Lekturepraxis. Vielmehr stellen die wiederholt auftretenden Bezuge auf Kants Begrifflichkeit fur ihn ein geeignetes Instrument dar, um die Entfaltung von Nietzsches Denken in aller Scharfe sichtbar zu machen. Die Kritik an Kant wird auf diese Weise zum Ausgangspunkt einer differenzierten Interpretation von Nietzsches perspektivistischer Philosophie der Macht im Sinne einer relationalen Ontologie. Damit versteht sich das Buch auch als Beitrag zur - vor allem im englischsprachigen Raum sehr lebendigen - Debatte um das Verhaltnis Nietzsches zu Kant. (shrink)

Do I cause global warming, climate change and their related harms when I go for a leisure drive with my gas-guzzling car? The current verdict seems to be that I do not; the emissions produced by my drive are much too insignificant to make a difference for the occurrence of global warming and its related harms. I argue that our verdict on this issue depends on what we mean by ‘causation’. If we for instance assume a simple counterfactual analysis of (...) causation according to which ‘C causes E’ means ‘if C had not occurred, E would not have occurred’, we must conclude that a single drive does not cause global warming. However, this analysis of causation is well-known for giving counterintuitive results in some important cases. If we instead adopt Lewis’s analysis of causation, it turns out that it is indeterminate whether I cause global warming when I go for a single drive. Still, in contexts where we seek to control or understand global warming, there is a pressure to adopt a more fragile view of this event. When we adopt such a view, it turns out that a single drive does cause global warming. This means that we cannot like Sinnott-Armstrong and Kingston and Sinnott-Armstrong reject the idea that I should refrain from going for a leisure drive simply because such a drive does not cause global warming.

In collective harm cases, bad consequences follow if enough people act in a certain way even though no such individual act makes a difference for the worse. Global warming, overfishing and Derek Parfit’s famous case of the harmless torturers are some examples of such harm. Shelly Kagan argues that there is a threshold such that one single act might trigger harm in all collective harm cases. Julia Nefsky points to serious shortcomings in Kagan’s argument, but does not show that his (...) conclusion is incorrect. I argue that our best theories of vagueness (the epistemic view of vagueness, three-valued logic, and supervaluationism) entail that there is a threshold in all collective harm cases. However, my analysis points to another problem with Kagan’s argument: the thresholds are not necessarily perceptible. Given the assumption that only perceptible differences matter morally, passing such a threshold does not necessarily trigger morally relevant harm, pace Kagan. Last, I consider two variants of Kagan’s argument and find both problematic. One controversially assumes that observational relations like ‘cannot perceive the difference between’ are transitive. The other problematically assumes that so called triangulation always is possible. (shrink)

Should you always be certain about what you should believe? In other words, does rationality demand higher-order certainty? First answer: Yes! Higher-order uncertainty can’t be rational, since it breeds at least a mild form of epistemic akrasia. Second answer: No! Higher-order certainty can’t be rational, since it licenses a dogmatic kind of insensitivity to higher-order evidence. Which answer wins out? The first, I argue. Once we get clearer about what higher-order certainty is, a view emerges on which higher-order certainty does (...) not, in fact, license any kind of insensitivity to higher-order evidence. The view as I will describe it has plenty of intuitive appeal. But it is not without substantive commitments: it implies a strong form of internalism about epistemic rationality, and forces us to reconsider standard ways of thinking about the nature of evidential support. Yet, the view put forth promises a simple and elegant solution to a surprisingly difficult problem in our understanding of rational belief. (shrink)

Orthodox Bayesianism is a highly idealized theory of how we ought to live our epistemic lives. One of the most widely discussed idealizations is that of logical omniscience: the assumption that an agent’s degrees of belief must be probabilistically coherent to be rational. It is widely agreed that this assumption is problematic if we want to reason about bounded rationality, logical learning, or other aspects of non-ideal epistemic agency. Yet, we still lack a satisfying way to avoid logical omniscience within (...) a Bayesian framework. Some proposals merely replace logical omniscience with a different logical idealization; others sacrifice all traits of logical competence on the altar of logical non-omniscience. We think a better strategy is available: by enriching the Bayesian framework with tools that allow us to capture what agents can and cannot infer given their limited cognitive resources, we can avoid logical omniscience while retaining the idea that rational degrees of belief are in an important way constrained by the laws of probability. In this paper, we offer a formal implementation of this strategy, show how the resulting framework solves the problem of logical omniscience, and compare it to orthodox Bayesianism as we know it.

The financial crisis that began in the US real-estate market in 2007 and culminated in a global economic slump showed bluntly how wrong financial risk models can be. This state of affairs has triggered a number of reactions and observations at the level of the specification and use of models and at a more conceptual/fundamental level. This article focuses on the epistemic features of such models – namely the nature, source, conditions of validity, structure and limits of the knowledge that (...) ‘well-specified’ models generate – so as to assess models in a balanced way, giving due weight to the fundamental determinants of their output and warning against overestimation of their possibilities; clarify the conditions under which models can be validly applied to economic and social relationships; render intelligible why the degree of accuracy that successful models would require is intrinsically unattainable; better understand models’ failure as evidenced by the crisis; and comment on the policy steps being undertaken to prevent similar financial crisis in the future. The analysis applies the principal tenets of critical realism to the daily preoccupations of risk management professionals and financial regulators alike. It is not intended as an intervention into critical realism. It draws on the works of Tony Lawson and Roy Bhaskar, and revisits relevant aspects of John Maynard Keynes’s work, connecting dots amongst them and marrying economic and philosophical analysis with day-to-day financial risk management and regulatory issues.

According to many philosophers and scientists, human sociality is explained by our unique capacity to “share” attitudes with others. The conditions under which mental states are shared have been widely debated in the past two decades, focusing especially on the issue of their reducibility to individual intentionality and the place of collective intentions in the natural realm. It is not clear, however, to what extent these two issues are related and what methodologies of investigation are appropriate in each case. In (...) this article, I propose a solution that distinguishes between epistemic and ontological interpretations of the demand for the conditions of reduction of collective intentionality. While the philosophical debate has contributed important insights into the former, recent advances in the cognitive sciences offer novel resources to tackle the latter. Drawing on Michael Tomasello’s research in the ontogeny of shared intentionality in early instances of interaction based on joint attention, I propose an empirically informed argument of what it would take to address the ontological question of irreducibility, thus making a step forward in the naturalization of collective intentionality.

The modelling of concepts, besides involving disciplines like philosophy of mind and psychology, is a fundamental and lively research problem in several artificial intelligence (AI) areas, such as knowledge representation, machine learning, and natural language processing. In this scenario, the most prominent proposed solutions adopt different (often incompatible) assumptions about the nature of such a notion. Each of these solutions has been developed to capture some specific features of concepts and support some specific (artificial) cognitive operations. This paper critically reviews (...) the most notable computational approaches to the representation of concepts. The main goals are (i) to provide a shared terminology for the desiderata of concepts and their computational representation; (ii) to classify and assess the heterogeneous computational approaches according to the provided terminology; (iii) to provide a reader who may not be very familiar with theories of concepts with an introduction to major themes in this research and with pointers to different research projects, and (iv) to offer philosophers, and potentially AI practitioners, a well-informed guide for selecting among various (and possibly competing) computational representations of concepts.

Nowadays, almost everyone seems to agree that science is facing an epistemological crisis – namely the replicability crisis – and that we need to take action. But as to precisely what to do or how...

Our aim in this chapter is to draw attention to what we see as a disturbing feature of conciliationist views of disagreement. Roughly put, the trouble is that conciliatory responses to in-group disagreement can lead to the frustration of a group's epistemic priorities: that is, the group's favoured trade-off between the "Jamesian goals" of truth-seeking and error-avoidance. We show how this problem can arise within a simple belief aggregation framework, and draw some general lessons about when the problem is most (...) pronounced. We close with a tentative proposal for how to solve the problem raised without rejecting conciliationism. (shrink)

This book offers a systematic account of Nietzsche's thought on the human mind. A central theme is the nature of and relation between the unconscious and conscious mind, relating Nietzsche's work to contemporary debates about consciousness and theory of mind.

Perspectives on Social Ontology and Social Cognition brings together contributions discussing issues arising from theoretical and empirical research on social ontology and social cognition. It is the first comprehensive interdisciplinary collection in this rapidly expanding area. The contributors draw upon their diverse backgrounds in philosophy, cognitive science, behavioral economics, sociology of science and anthropology. -/- Based largely on contributions to the first Aarhus-Paris conference held at the University of Aarhus in June 2012, the book addresses such questions as: If the (...) reference of concepts like money is fixed by collective acceptance, does it depend on mechanisms that are distinct from those which contribute to understanding the reference of concepts of other kinds of entity? What psychological and neural mechanisms, if any, are involved in the constitution, persistence and recognition of social facts? -/- The editors' introduction considers strands of research that have gained increasing importance in explaining the cognitive foundations of acts of sociality, for example, the theory that humans are predisposed and motivated to engage in joint action with con-specifics thanks to mechanisms that enable them to share others' mental states. The book also presents a commentary written by John Searle for this volume and an interview in which the editors invite Searle to respond to the various questions raised in the introduction and by the other contributors.

According to the prevailing paradigm in social-cognitive neuroscience, the mental states of individuals become shared when they adapt to each other in the pursuit of a shared goal. We challenge this view by proposing an alternative approach to the cognitive foundations of social interactions. The central claim of this paper is that social cognition concerns the graded and dynamic process of alignment of individual minds, even in the absence of a shared goal. When individuals reciprocally exchange information about each other's (...) minds processes of alignment unfold over time and across space, creating a social interaction. Not all cases of joint action involve such reciprocal exchange of information. To understand the nature of social interactions, then, we propose that attention should be focused on the manner in which people align words and thoughts, bodily postures and movements, in order to take one another into account and to make full use of socially relevant information.

Many theories of rational belief give a special place to logic. They say that an ideally rational agent would never be uncertain about logical facts. In short: they say that ideal rationality requires "logical omniscience." Here I argue against the view that ideal rationality requires logical omniscience on the grounds that the requirement of logical omniscience can come into conflict with the requirement to proportion one’s beliefs to the evidence. I proceed in two steps. First, I rehearse an influential line (...) of argument from the "higher-order evidence" debate, which purports to show that it would be dogmatic, even for a cognitively infallible agent, to refuse to revise her beliefs about logical matters in response to evidence indicating that those beliefs are irrational. Second, I defend this "anti-dogmatism" argument against two responses put forth by Declan Smithies and David Christensen. Against Smithies’ response, I argue that it leads to irrational self-ascriptions of epistemic luck, and that it obscures the distinction between propositional and doxastic justification. Against Christensen’s response, I argue that it clashes with one of two attractive deontic principles, and that it is extensionally inadequate. Taken together, these criticisms will suggest that the connection between logic and rationality cannot be what it is standardly taken to be—ideal rationality does not require logical omniscience.

Madhyamaka philosophers, like most Buddhist authors writing in Sanskrit and Pāli, often express their philosophical positions through the etymological expansion and interpretation of specific key terms. Their format and style reflect an attitude towards language that, while being largely shared by the entire Sanskrit tradition, is also attuned to uniquely Buddhist concerns. I shall here reconstruct and discuss some Sanskrit and Pāli etymologies, offering a possible context for the understanding of Madhyamaka thought in India. As it would be unfeasible to (...) analyze a large amount of terms, I focus on a few expressions that bear upon the question of how Mādhyamikas understand language, both as actual linguistic expression and, more broadly/figuratively, as the activity of conceptualization. I will propose a specific reading of the Sanskrit sources in terms of linguistic, lexical, and philosophical analysis. In particular, I interpret Candrakīrti as advocating a layered view of conventional truths. He restricts the perceptions and thoughts that may qualify as conventionally valid, so as to exclude impaired perception or distorting philosophical stances. These restrictions are embedded in his etymological explanation of key philosophical terms. In brief, when Candrakīrti discusses ‘worldly conventions’ or refers to ‘what is established in the world’, not everyone fits in his ‘world’. (shrink)

While many philosophers have agreed that evidence of disagreement is a kind of higher-order evidence, this has not yet resulted in formally precise higher-order approaches to the problem of disagreement. In this paper, we outline a simple formal framework for determining the epistemic significance of a body of higher-order evidence, and use this framework to motivate a novel interpretation of the popular “equal weight view” of peer disagreement—we call it the Variably Equal Weight View (VEW). We show that VEW differs (...) from the standard Split the Difference (SD) interpretation of the equal weight view in almost all cases of peer disagreement, and use our formal framework to explain why SD has seemed attractive but is in fact misguided. A desirable feature of VEW, we argue, is that it gives rise to plausible instances of synergy—an effect whereby the parties to a disagreement should become more (or less) confident in the disputed proposition than any of them were prior to disagreement. Lastly, we show how VEW may be generalized to cases of non-peer disagreement. (shrink)

The aim of this article is to present Paul Natorp’s position in the debate over the allocation of chairs in philosophy to experimental psychology. Natorp triggered the public controversy within psychology when an experimental psychologist, Eric Jaensch, was awarded the chair of Hermann Cohen in 1912. Natorp published an editorial in the «Frankfurter Zeitung» and in the following year, 1913, submitted a petition for the establishment of new chairs for experimental psychology in Germany. In this way, Natorp hoped to prevent (...) the abolition of “pure” philosophy from German universities. When the controversy began, Natorp wrote another essay, Philosophie und Psychologie. Natorp’s article aimed to clarify the logical domains of philosophy and psychology and to present his philosophical psychology as a solution to their conceptual overlap. Natorp’s article is also important for Natorpforschung because it was the last time that Natorp discussed his psychological point of view, only to apparently abandon his project of a philosophical psychology.

The late Nietzsche defended a position which he sometimes to refers as ‘sensualism’ and which consists of two main theses: senses ‘do not lie’ (T1) and sense organs are ‘causes’ (T2). Two influential interpretations of this position have been proposed by Clark and Hussain, who also address the question whether Nietzsche's late sensualism is (Hussain) or not (Clark) compatible with the epistemological view which he held in his previous work and which has been dubbed the ‘falsification thesis’ (FT). In my (...) paper I will show that both readings raise substantial difficulties and propose an alternative account of Nietzsche's sensualism. In particular, I will argue: (a) that according to Nietzsche the representational content of sensory experience ‘does not lie’ since it is physically grounded in causal exchanges with the external world which are mediated by sense organs; (b) that Nietzsche believes that the claim that senses ‘do not lie’ is also true of the phenomenal, qualitative content of sensory experience; and (c) that FT, despite its prima facie tension with (a) and (b), fit well Nietzsche's sensualism.

In this paper, we present a new account of teleological reasons, i.e. reasons to perform a particular action because of the outcomes it promotes. Our account gives the desired verdict in a number of difficult cases, including cases of overdetermination and non-threshold cases like Parfit’s famous _Drops of water._ The key to our account is to look more closely at the metaphysics of causation. According to Touborg (_The dual nature of causation_, 2018), it is a necessary condition for causation that (...) a cause increases the security of its effect. Building on this idea, we suggest, roughly, that you have a teleological reason to act in a certain way when doing so increases the security of some good outcome. This represents a middle way between the proposal that you have a reason to act in a certain way just in case this _would_ cause a good outcome and the proposal that you have a reason to act in a certain way just in case this _could_ cause a good outcome.

A proof-theoretic test for paradoxicality was famously proposed by Tennant: a paradox must yield a closed derivation of absurdity with no normal form. Drawing on the remark that all derivations of a given proposition can be transformed into derivations in normal form of a logically equivalent proposition, we investigate the possibility of paradoxes in normal form. We compare paradoxes à la Tennant and paradoxes in normal form from the viewpoint of the computational interpretation of proofs and from the viewpoint of (...) proof-theoretic semantics. (shrink)

Guessing is a familiar activity, one we engage in when we are uncertain of the answer to a question under discussion. It is also an activity that lends itself to normative evaluation: some guesses are better than others. The question that interests me here is what makes for a good guess. In recent work, Dorst and Mandelkern have argued that good guesses are distinguished from bad ones by how well they optimize a tradeoff between accuracy and specificity. Here I argue (...) that Dorst and Mandelkern’s implementation of this idea fails to satisfy some plausible constraints on good guesses, and I develop an alternative implementation that satisfies the relevant constraints. The result is a new account of good guesses which retains the positive aspects of Dorst and Mandelkern’s proposal, but without the drawbacks. (shrink)

People don't always speak the truth. When they don't, we do better not to trust them. Unfortunately, that's often easier said than done. People don't usually wear a ‘Not to be trusted!’ badge on their sleeves, which lights up every time they depart from the truth. Given this, what can we do to figure out whom to trust, and whom not? My aim in this paper is to offer a partial answer to this question. I propose a heuristic—the “Humility Heuristic”—which (...) is meant to help guide our search for trustworthy advisors. In slogan form, the heuristic says: people worth trusting admit to what they don't know. I give this heuristic a precise probabilistic interpretation, offer a simple argument for it, defend it against some potential worries, and demonstrate its practical worth by showing how it can help address some difficult challenges in the relationship between experts and laypeople.

Nietzsche believes that we do not know our own actions, nor their real motives. This belief, however, is but a consequence of his assuming a quite general skepticism about introspection. The main aim of this paper is to offer a reading of this last view, which I shall call the Inner Opacity (IO) view. In the first part of the paper I show that a strong motivation behind IO lies in Nietzsche’s claim that self-knowledge exploits the same set of cognitive (...) capacities as well as the same folk-psychological framework involved in outward-directed mind-reading. In the second part I turn to Nietzsche’s view of agency and argue that he sees a fundamental discrepancy between the conscious attitudes we have introspective access to, on the one hand, and the subpersonal processes and states occurring at the unconscious level of the drives, on the other hand.

The first Chapter of Nāgārjuna’s Mūlamadhyamakakārikā offers a critique of causation that includes the Abhidharmic category of the ‘four conditions’. Following the South-Asian commentarial tradition, this article discusses the precise relationship between Madhyamaka philosophy and its fundamental Abhidharmic background. What comes to light is a more precise assessment of Madhyamaka ideas about viable conventions, understood as the process of dependent arising. Since this is primarily in the sense of conceptual dependence, it involves sentiency as a necessary causal element, and the (...) relationship between sentiency and conceptuality is highlighted by Nāgārjuna and his commentators. Viable conventions exclude the possibility of a non-contingent core, and the systems and categories that revolve around such non-contingent element (ātman) are discarded by the Madhyamaka even at a conventional level.

Statistical evidence is pervasive in medicine. In this chapter we will focus on the reliability of randomized clinical trials (RCTs) conducted to test the safety and efficacy of medical treatments. RCTs are scientific experiments and, as such, we expect them to be replicable: if we repeat the same experiment time and again, we should obtain the same outcome (Norton 2015). The statistical design of the test should guarantee that the observed outcome is not a random event, but rather a real (...) effect of the treatments administered. However, for more than a decade now, we have been discussing a replicability crisis across different experimental disciplines including medicine: the outcomes of trials published in very prestigious journals often disappear when the experiment is repeated (see, e.g., Lehrer 2010, Begley and Ellis 2012, Horton 2015). -/- There are different accounts of the reason for this replicability crisis, ranging from scientific fraud to lack of institutional incentives to double-check someone else’s results. In this chapter we will use the replicability crisis as a thread to introduce some central issues in the design of scientific experiments in medicine. First, in section 1, we will see how replicability and statistical significance are connected: we can only make sense of the p-value of a trial outcome within a series of replications of the test. But in order to conduct these replications properly, we need to agree on the proper design of the experiment we are going to repeat. In particular, we need to prevent the preferences of the experimenters from biasing the outcome of the experiment. If there is such a bias, when the experiment is replicated by a third party, the observed outcome will vanish. In section 2, we will argue that trialists need to agree on the debiasing procedures and the statistical quality controls that feature in the trial protocol, if they want the outcome to be replicable. In section 3, we will make two complementary points. On the one hand, replicability per se is not everything: we need trial outcomes that are not only statistically significant but also clinically relevant. On the other hand, trials are not everything: the experts analyzing the evidence can improve the reliability of statistical evidence, although they sometimes fail; we need to further study how they make their decisions. In section 4, we will use a controversy about the overprescription of statins to show how non-replicable effects are obtained in trials and how experts may fail at detecting such flaws, if the commercial interests are big enough.

What does it mean to enact a jazz beat as a creative performer? This article offers a critical reading of Iyer’s much-cited theory on rhythmic enaction. We locate the sonic environment approach in Iyer’s theory, and criticize him for advancing a one-to-one relationship between everyday perception and full-fledged aural competence of jazz musicians, and for comparing the latter with non-symbolic behaviour of non-human organisms. As an alternative, we suggest a Merleau-Ponty-inspired concept of rhythmic enaction, which we call the enactive communicative (...) approach. Key to this approach is the fact that jazz musicians play by ear, and that the beat emerges because of reciprocal, real-time aural communication. From this perspective, we outline the temporality of a jazz beat as a holistic and dialectical temporal structure. Throughout the discussions, we use John Coltrane’s ‘Trane’s Slo Blues’ as a point of reference. (shrink)

The traditional possible-worlds model of belief describes agents as ‘logically omniscient’ in the sense that they believe all logical consequences of what they believe, including all logical truths. This is widely considered a problem if we want to reason about the epistemic lives of non-ideal agents who—much like ordinary human beings—are logically competent, but not logically omniscient. A popular strategy for avoiding logical omniscience centers around the use of impossible worlds: worlds that, in one way or another, violate the laws (...) of logic. In this paper, we argue that existing impossible-worlds models of belief fail to describe agents who are both logically non-omniscient and logically competent. To model such agents, we argue, we need to ‘dynamize’ the impossible-worlds framework in a way that allows us to capture not only what agents believe, but also what they are able to infer from what they believe. In light of this diagnosis, we go on to develop the formal details of a dynamic impossible-worlds framework, and show that it successfully models agents who are both logically non-omniscient and logically competent.

In this paper, we present a new semantic framework designed to capture a distinctly cognitive or epistemic notion of meaning akin to Fregean senses. Traditional Carnapian intensions are too coarse-grained for this purpose: they fail to draw semantic distinctions between sentences that, from a Fregean perspective, differ in meaning. This has led some philosophers to introduce more fine-grained hyperintensions that allow us to draw semantic distinctions among co-intensional sentences. But the hyperintensional strategy has a flip-side: it risks drawing semantic distinctions (...) between sentences that, from a Fregean perspective, do not differ in meaning. This is what we call the ‘new problem’ of hyperintensionality to distinguish it from the ‘old problem’ that faced the intensional theory. We show that our semantic framework offers a joint solution to both these problems by virtue of satisfying a version of Frege’s so-called ‘equipollence principle’ for sense individuation. Frege’s principle, we argue, not only captures the semantic intuitions that give rise to the old and the new problem of hyperintensionality, but also points the way to an independently motivated solution to both problems.

Epistemic logics based on the possible worlds semantics suffer from the problem of logical omniscience, whereby agents are described as knowing all logical consequences of what they know, including all tautologies. This problem is doubly challenging: on the one hand, agents should be treated as logically non-omniscient, and on the other hand, as moderately logically competent. Many responses to logical omniscience fail to meet this double challenge because the concepts of knowledge and reasoning are not properly separated. In this paper, (...) I present a dynamic logic of knowledge that models an agent’s epistemic state as it evolves over the course of reasoning. I show that the logic does not sacrifice logical competence on the altar of logical non- omniscience. (shrink)
