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)

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)

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.

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)

In his contribution to this special issue, Hindriks considers the Security Principle, an account of pro tanto obligations based on our account of reasons (Gunnemyr and Touborg 2023a). According to the Security Principle, you have a pro tanto obligation not to perform an action that makes a harm more secure. Hindriks raises two objections to this account. First, that it is too flexible; second, that it gives wrong verdicts when agents are robustly unwilling to act in a certain way. Here, (...) we respond to Hindriks’ objections and argue that Hindriks’ account, the Threshold Principle, gives counterintuitive verdicts in preemption and low-probability cases. (shrink)

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)

How can imitation lead to free musical expression? This article explores the role of auditory imitation in jazz. Even though many renowned jazz musicians have assessed the method of imitating recorded music, no systematic study has hitherto explored how the method prepares for aural jazz improvisation. The article picks up an assumption presented by Berliner (1994), suggesting that learning jazz by aural imitation is “just like” learning a mother tongue. The article studies three potential stages in the method, comparing with (...) imitative, rhythmic, multimodal, and protosymbolic behavior of infant perception (building on the works of Stern, Trevarthen, and Merleau-Ponty). The demonstrations of the aural-imitation method draw on pedagogic experiences accumulated since 1979 in the Jazz Program at the Norwegian University of Science and Technology. By analyzing structures of behavior suggested by the method, the article indicates key traits that render aural jazz improvisation possible, such as a fundamental sense of rhythm, formation of symbolic behavior, joint musical attention, and the facility to “hear via the other.” In conclusion, we critically address a frequent theoretical model describing musical improvisation as a synthesis of discrete elements or building blocks.

Leibniz’s binary numeral system is generally studied for its arithmetical relevance, but the analysis of several unpublished manuscripts shows that from the very beginning Leibniz also envisaged a new form of algebra in the context of dyadics based on the idea that its letters can only express numbers that are either 1 or 0. In this paper, I shall present the most notable results of this binary algebra: the determination of the algorithm for the expansion of squares and the development (...) of the positional notation used to express any possible number. These achievements explain the priority of dyadics over any other numeral system in Leibniz’s mind and his impressive work on the classification of numbers which was facilitated by tools and notions which were only accessible to him at that time.

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.

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.

Through the mental alignment that sustains social interactions, the minds of individuals are shared. One interpretation of shared intentionality involves the ability of individuals to perceive features of the action scene from the perspective of the group (the ). This first-person plural approach in social cognition is distinct from and preferable to the second-person approach proposed in the target article.

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.

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.

This paper investigates the phenomenological status of musical affordances through a Gadamerian focus on human communication. With an extra emphasis on Reybrouck’s much-cited affordance-driven theory, I locate fundamental premises in the affordance concept. By initiating a dialogue with Gadamer’s perspective, I suggest a slight yet important shift of perspective that allows us to see an autonomous, transformative, and intrinsically active ‘ideality’ potentially emerging in music. In the final section, I try to demonstrate how Gadamer’s perspective is supported by recent empirical (...) studies on communicative musicality and child development, and allows us to see how protoversions of the transformative ‘ideality’ are already present at the beginning of human life.

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)

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 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.

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.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Nietzsche’s Ethics by Thomas SternMattia RiccardiThomas Stern, Nietzsche’s Ethics Cambridge: Cambridge University Press, 2020. 69 pp. ISBN: 9781108713320. Paper, $22.00.Thomas Stern sets out his approach in this “Cambridge Element” on Nietzsche’s ethics in a bold and straightforward way: “My own intention is to stay very close to the texts, to read them in light of what we know about Nietzsche’s intellectual background, and to present the philosophical ideas (...) found in them as clearly, neutrally and thoroughly as possible” (3). As a result, Stern guesses, the “Nietzsche on display in these pages may seem, in places, dated, wrong-headed and extremely unappealing.” In my case, the guess is mostly correct. Fortunately, there are reasons to doubt that Stern’s Nietzsche is also the “real one,” contrary to what is claimed. (I don’t mean to suggest Nietzsche is never “dated,” “wrong-headed,” or “extremely unappealing.”)Stern, who focuses on the ethics of the late Nietzsche—roughly, from BGE onward—claims it consists of two basic claims. The first claim is a descriptive one—the “Life Theory”—to the effect that striving for power is an essential feature of life as such: “Living and power seeking cannot be pulled apart” (6). Power seeking, in turn, is manifested in behaviors that could be generically described as aggressive. A suggestive passage: “life itself is essentially a process of appropriating, injuring, overpowering the alien and the weaker, oppressing, being harsh, imposing your own form, incorporating, and at least, the very least, exploiting” (BGE 259; if not otherwise indicated, Nietzsche’s works are quoted from the Cambridge University Press translations). The second claim—the “Normative Command”—is directly derived from the descriptive one: “it is ethical to further the goals of Life and it is unethical to impede them” (11). On this reading, Nietzsche turns out to defend a version of metaethical realism: the very nature of (biological) reality gives us an objective criterion for what is ethical. As Stern puts it, “His ethics track what he takes to be a deep, fundamental fact about living things, the Life Theory, which applies at all times and in all places” (23). [End Page 226]In my view, there are many problems with this reading, both interpretive and conceptual. To start with, although Nietzsche often supplies characterizations of life like the one in BGE 259, it is not clear that they should be understood as (merely) descriptive. BGE 22 makes explicit that a claim to the effect that nature (considered here as the object of physics) is a “tyrannically ruthless and pitiless execution of power claims” cannot count as part of a description of the (physical) world. Of course, Nietzsche is not talking here about life. But that he explicitly classifies a will to power claim as “interpretation,” and not as part of (physical) nature’s “text,” should warn readers from taking such claims to be (merely) descriptive (even if they often look like that)—a point already made by Maudemarie Clark in Nietzsche on Truth and Philosophy ([Cambridge: Cambridge University Press, 1990], 222–23). A similar worry also applies to the idea, at the heart of the Normative Command, that life has certain goals. For although there are passages where Nietzsche talks of life’s goals, the problem is again whether they are about “goals” that “life” really has. Sometimes Nietzsche writes that nature lacks any goal whatsoever—it is “indifferent without measure, without purpose and regard” (BGE 9). And sometimes he writes that goals (and values) are a human product. (See, for instance, TI “Errors” 8: “We have invented the concept of ‘purpose’: there are no purposes in reality”; on values, see Z I “Thousand and One Goals.”) Thus, the very status of Nietzsche’s claims about the essence of life and its goals is not as straightforward as Stern suggests.Another kind of textual evidence points in the same direction. For although it is true that Nietzsche often describes life as such as power seeking, as in BGE 259, this is not always the case. In the very late writings from which Stern draws a great deal of the textual evidence to back up his... (shrink)

Titelbaum Oxford studies in epistemology, 2015) has recently argued that the Enkratic Principle is incompatible with the view that rational belief is sensitive to higher-order defeat. That is to say, if it cannot be rational to have akratic beliefs of the form “p, but I shouldn’t believe that p,” then rational beliefs cannot be defeated by higher-order evidence, which indicates that they are irrational. In this paper, I distinguish two ways of understanding Titelbaum’s argument, and argue that neither version is (...) sound. The first version can be shown to rest on a subtle, but crucial, misconstrual of the Enkratic Principle. The second version can be resisted through careful consideration of cases of higher-order defeat. The upshot is that proponents of the Enkratic Principle are free to maintain that rational belief is sensitive to higher-order defeat. (shrink)

The institutionalization of a rights-based proportionality review shares a number of salient features and puzzles with the practice of contestation that the Socrates of the early Platonic dialogues became famous for. Understanding the point of Socratic contestation, and its role in a democratic polity, is also the key to understanding the point of proportionality based rights review. To begin with, when judges decide cases within the proportionality framework they do not primarily interpret authority. They assess reasons. Not surprisingly, they, like (...) Socrates, have been prone to the charge that they offend the values and traditions of the community. The article discusses four types of pathologies that occasionally infect democratic decision-making that rights-based proportionality review is particularly suited to identify. But more basic and equally important is a second kind of justification: Proportionality-based judicial review institutionalizes a right to contest the acts of public authorities and demand a public reasons-based justification. Having a legal remedy that allows for the contestation of acts by public authorities before an impartial and independent court and demanding its justification in terms of public reason is as basic a commitment of liberal democracy as the right to vote. The real question is not whether judicial review is democratically legitimate, but how judicial institutions ought to be structured to best serve their democracy-enhancing and rights protecting purpose. If Socrates was right to insist that the practice of contestation he engaged in deserves the highest praise in a democratic polity, it is equally true that a well structured and appropriately embedded court engaged in rights based proportionality review deserves to be embraced as a vital element of liberal constitutional democracy.

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.
