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.

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)

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.

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.

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)

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.

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.

This paper investigates the argument that substantiates Nietzsche's refusal of teh Kantian concept of thing in itself. As Maudmarie Clark points out, Nietzsche dismisses this notion because he views it as self-contradictory. The main concern of the paper will be to account for this position. In particular, the two main theses defended here are that the argument underlying Nietzsche's claim is that the concept of thing in itself amounts to the inconsistent idea of a propertyless thing and that this argument (...) is a sound one. Finally, I will show that the reading proposed allows a deflationary response to the objection that Nietzsche's will to power is simply a new version of the post-Kantian thing in itself.Dieser Aufsatz untersucht die Argumentation, die Nietzsches Zurückweisung des kantischen Begriffs des Dings an sich untermauert. Wie Maudmarie Clark betont, berwift Nietzsche diesen Begriff als selbstwidersprüchlich. Hauptanliegen des Aufsatzes ist, dies deutlich zu machen. Insbesondere werden folgende zwei Thesen vertrenen: dass das Nietzsches Position zugrundeliegende Argument darin besteht, der Begriff des Dings an sich sei der inkonsistente Begriff eines eigenschaftslosen Dings; dass dieses Argument stichhaltig ist. Schließlich wird gezeigt, dass diese Interpretation eine delfationäre Antwort auf den Einwand ermöglicht, Nietzsches Wille zur Macht sei einfach eine neue Variante des postkantischen Dings an sich.

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.

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.

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 De Trinitate XII Augustine refuses the idea that a family could be the image of God. This is curious, because the theologian that in De Trinitate elaborates a “communitarian model” of the Trinity – the Lover, the Beloved and the Love – at the same time does not see the image of God in the first natural community, the family. The purpose of this paper is to show the deeper reasons for this refutation. After the exposition of Augustine’s argument, (...) the paper identifies Augustine’s polemical reference to a part of the Eastern Tradition, which used the example of the first family (Adam, Eve and Abel/Seth) in order to express the mystery of the Trinity. It examines also how the example of the first family was used by Gregory of Nazianzus in his fifth theological discourse (which some scholars identify as the possible source of the idea of the family as the image of God for Augustine) in a trinitarian way. This study then considers two aspects of Augustine’s argument: that his refutation is not justified by the association of the Holy Spirit with the mother and the bride; that the real reason for it is exegetical, and dependent upon Augustine’s reading of Gn. 1:26. Finally the paper shows that the view of gender differences as merely corporeal is what prevents the Doctor of Grace from reading Gn. 1:27 in a relational-dialogical way to express the intimate communion of the Trinity.

This paper analyses the importance of the forest in understanding the Old French Partonopeus de Blois. The forest embodies the dual nature of the romance, mixing religious and supernatural elements. It provides a structural framework for the action, as both parts of the romance start with a journey into the forest: it is the passage to the Otherworld, the frontier between reality and the unknown. Placed at the limit of the civilised world, the forest is the space of perigrinations and (...) of reconciliation, both with other characters and with God. In Partonopeus the forest also leads to the sea, the next step in the journey to the Otherworld, and the passage from one realm of reality to the other is achieved with the help of an animal. The author also reflects on the otherworldly roles of Melior and Uraque, in the traditions of the fairy lover and the healing fairy. (shrink)

In this article we use proportional hazards models to examine how low-level processes affect the probability of making a saccade over time, through the period of fixation, during reading. We apply the Cox proportional hazards model to investigate how launch distance (relative to word beginning), fixation location (relative to word center), and word frequency affect the hazard of a saccadic response. This model requires that covariates have a constant impact on the hazard over time, the assumption of proportional hazards. We (...) show that this assumption is not supported. The impact of the covariates changes with the time passed since fixation onset. To account for the non-proportional hazards we fit step functions of time, resulting in a model with time-varying effects on the hazard. We evaluate the ability to predict the timing of saccades on held-out fixation data. The model with time-varying effects performs better in predicting the timing of saccades for fixations as short as 100 ms and as long as 500 ms, when compared both to a baseline model without covariates and a model which assumes constant covariate effects. This result suggests that the time-varying effects model better recovers the time course of low-level processes that influence the decision to move the eyes. (shrink)

A major open question in the borderlands between epistemology and philosophy of science concerns whether Bayesian updating and abductive inference are compatible. Some philosophers—most influentially Bas van Fraassen—have argued that they are not. Others have disagreed, arguing that abduction, properly understood, is indeed compatible with Bayesianism. Here we present two formal results that allow us to tackle this question from a new angle. We start by formulating what we take to be a minimal version of the claim that abduction is (...) a rational pattern of reasoning. We then show that this minimal abductivist principle, when combined with Bayesian updating by conditionalization, places surprisingly strong and controversial constraints on how we must measure explanatory power. The lesson is not that Bayesianism is definitely incompatible with abduction, but that both compatibilism and incompatibilism have hitherto unrecognized consequences. We end the paper by formulating these consequences in the form of a trilemma. (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)

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)

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)

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.

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.

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.

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.

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.

Based on Kolchinsky and Wolpert’s work on the semantics of autonomous agents, I propose an application of Mathematical Logic and Probability to model cognitive processes. In this work, I will follow Bateson’s insights on the hierarchy of learning in complex organisms and formalize his idea of applying Russell’s Type Theory. Following Weaver’s three levels for the communication problem, I link the Kolchinsky–Wolpert model to Bateson’s insights, and I reach a semantic and conceptual hierarchy in living systems as an explicative model (...) of some adaptive constraints. Due to the generality of Kolchinsky and Wolpert’s hypotheses, I highlight some fundamental gaps between the results in current Artificial Intelligence and the semantic structures in human beings. In light of the consequences of my model, I conclude the paper by proposing a general definition of knowledge in probabilistic terms, overturning de Finetti’s Subjectivist Definition of Probability.

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)

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.

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.

Habituation, a form of non‐associative learning, isno longer studied exclusively within the fields of psychology and neuroscience. Indeed, the same stimulus–response pattern is observed at the molecular, cellular, and organismal scales and is not dependent upon the presence of neurons. Hence, a more inclusive theory is required to accommodate aneural forms of habituation. Here an abstraction of the habituation process that does not rely upon particular biological pathways or substrates is presented. Instead, five generalizable elements that define the habituation process (...) are operationalized. The formulation can be applied to interrogate systems as they respond to several stimulation paradigms, providing new insights and supporting existing behavioral data. The model can be used to deduce the relative contribution of elements that contribute to the measurable output of the system. The results suggest that habituation serves as a general biological strategy that any system can implement to adaptively respond to harmless, repetitive stimuli. (shrink)

This article discusses the contribution of the Capability Approach within the theoretical framework of moral philosophy, political theory and political philosophy. Starting from delineating the contours to properly interpret this contemporary political doctrine, the A. recognises its primary roots in the human emotional development, as outlined by the American political philosopher Martha Nussbaum. Then the A. offers a comparative review of the Nussbaumean conception of emotions in Upheavals of Thought as well as in the most recent contributions on the topic. (...) The concepts of fear and security prompted us to the discussion, a posteriori from the cognitive development and the ‘securisation’ of human rights as promoted by education (especially in lifelong learning of children and women).

Although Habermas has never worked out a conception of virtue and indeed criticizes this notion whenever he uses it, his theory crucially depends on the virtuous attitude of participants in discourse — be it in the realm of democracy and law or that of morality. In this paper, in which I deal only with the ethical foundations of morality, I argue first that the norms of discourse which are gained from a presuppositional analysis of speech as such have to be (...) complemented by the sensitive perception on the side of the recipients. Only when the claims are understood in their full significance for the speaker does the discourse live up to the ideal which is already anticipated in every speech act. This presuppositional analysis shows secondly that it is mainly the virtuous attitude that is morally relevant and not those capacities for acting morally that the agent already possesses. However, the virtuous attitude genuinely entails the obligation to strive to perfect all those capacities that enable us to sensitively understand the other's claim. A discussion of the capacities that have to be promoted leads to the singling out of sensitivity as contrasted to immediate empathy. It is the reflexive transcendence of the agent's evaluative patterns that allows this emotion to sit well with a post-conventional morality. Finally, I discuss a possible caveat of Wellmer and Habermas who might claim that the proposed conception of virtue would only be valid for participants in discourse, but not for agents acting in the life-world. However, because the discursive virtue is of wide latitude, it does not fall under this objection. (shrink)

Uitleg van het zogenoemde 'ontologisch godsbewijs' van Anselmus van Canterbury (gestorven in 1109).

This paper investigates if and to what point it is possible to trade on news sentiment and if deep learning, given the current hype on the topic, would be a good tool to do so. DL is built explicitly for dealing with significant amounts of data and performing complex tasks where automatic learning is a necessity. Thanks to its promise to detect complex patterns in a dataset, it may be appealing to those investors that are looking to improve their trading (...) process. Moreover, DL and specifically LSTM seem a good pick from a linguistic perspective too, given its ability to “remember” previous words in a sentence. After having explained how DL models are built, we will use this tool for forecasting the market sentiment using news headlines. The prediction is based on the Dow Jones industrial average by analyzing 25 daily news headlines available between 2008 and 2016, which will then be extended up to 2020. The result will be the indicator used for developing an algorithmic trading strategy. The analysis will be performed on two specific cases that will be pursued over five time-steps and the testing will be developed in real-world scenarios. (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.
