Human errors are widely considered among the major causes of road accidents. Furthermore, it is estimated that more than 90% of vehicle crashes causing fatal and permanent injuries are directly related to mental tiredness, fatigue, and drowsiness of the drivers. In particular, driving drowsiness is recognized as a crucial aspect in the context of road safety, since drowsy drivers can suddenly lose control of the car. Moreover, the driving drowsiness episodes mostly appear suddenly without any prior behavioral evidence. The present (...) study aimed at characterizing the onset of drowsiness in car drivers by means of a multimodal neurophysiological approach to develop a synthetic electroencephalographic -based index, able to detect drowsy events. The study involved 19 participants in a simulated scenario structured in a sequence of driving tasks under different situations and traffic conditions. The experimental conditions were designed to induce prominent mental drowsiness in the final part. The EEG-based index, so-called “MDrow index”, was developed and validated to detect the driving drowsiness of the participants. The MDrow index was derived from the Global Field Power calculated in the Alpha EEG frequency band over the parietal brain sites. The results demonstrated the reliability of the proposed MDrow index in detecting the driving drowsiness experienced by the participants, resulting also more sensitive and timely sensible with respect to more conventional autonomic parameters, such as the EyeBlinks Rate and the Heart Rate Variability, and to subjective measurements.

Technologies like passive brain-computer interfaces can enhance human-machine interaction. Anyhow, there are still shortcomings in terms of easiness of use, reliability, and generalizability that prevent passive-BCI from entering real-life situations. The current work aimed to technologically and methodologically design a new gel-free passive-BCI system for out-of-the-lab employment. The choice of the water-based electrodes and the design of a new lightweight headset met the need for easy-to-wear, comfortable, and highly acceptable technology. The proposed system showed high reliability in both laboratory and (...) realistic settings, performing not significantly different from the gold standard based on gel electrodes. In both cases, the proposed system allowed effective discrimination between low and high levels of workload, vigilance, and stress even for high temporal resolution. Finally, the generalizability of the proposed system has been tested through a cross-task calibration. The system calibrated with the data recorded during the laboratory tasks was able to discriminate the targeted human factors during the realistic task reaching AUC values higher than 0.8 at 40 s of temporal resolution in case of vigilance and workload, and 20 s of temporal resolution for the stress monitoring. These results pave the way for ecologic use of the system, where calibration data of the realistic task are difficult to obtain. (shrink)

The paper defends a naturalistic version of modal actualism according to which what is metaphysically possible is determined by dispositions found in the actual world. We argue that there is just one world – this one – and that all genuine possibilities are grounded in the dispositions exemplified in it. This is the case whether or not those dispositions are manifested. As long as the possibility is one that would obtain were the relevant disposition manifested, it is a genuine possibility. (...) Furthermore, by starting from actual dispositional properties and branching out, we are able to countenance possibilities quite far removed from any state of affairs that happens to obtain, while still providing a natural and actual grounding of possibility. Stressing the importance of ontological considerations in any theory of possibility, it is argued that the account of possibility in terms of dispositional properties provides a more palatable ontology than those of its competitors. Coming at it from the other direction, the dispositional account of possibility also provides motivation for taking an ontology of dispositions more seriously. (shrink)

This translated volume by Andrea Borghini and Elena Casetta (original title: _Filosofia della biologia_) introduces a wide spectrum of key philosophical problems related to life sciences in a clear framework and an accessible style, with a special emphasis on metaphysical questions.

– The paper defends a naturalistic version of modal actualism according to which what is metaphysically possible is determined by dispositions found in the actual world. We argue that there is just one world—this one—and that all genuine possibilities are anchored by the dispositions exemplified in this world. This is the case regardless of whether or not those dispositions are manifested. As long as the possibility is one that would obtain were the relevant disposition manifested, it is a genuine possibility. (...) Furthermore, by starting from actual dispositional properties and branching out, we are able to include possibilities that are quite far removed from any state of affairs that happens to obtain, while still providing a natural and actual grounding of possibility. Stressing the importance of ontological considerations in any theory of possibility, it is argued that the account of possibility in terms of dispositional properties provides a more palatable ontology than those of its competitors. Coming at it from the other direction, the dispositional account of possibility also provides motivation for taking an ontology of dispositions more seriously. As well as the relevant dispositional notions required to lay out the view, the paper discusses the dispositional realism needed as the basis for the account of possibility. (shrink)

World food production is facing exorbitant challenges like climate change, use of resources, population growth, and dietary changes. These, in turn, raise major ethical and political questions, such as how to uphold the right to adequate nutrition, or the right to enact a gastronomic culture and to preserve the conditions to do so. Proposals for utopic solutions vary from vertical farming and lab meat to diets filled with the most fanciful insects and seaweeds. Common to all proposals is a polarized (...) understanding of food and diets, famously captured by Warren Belasco in the contraposition between technological fixes and anthropological fixes. According to the first, technology will deliver clean, just, pleasurable, affordable food; future generations will not need to adjust much of their dietary cultures. According to the second, future generations should dramatically change their dietary habits (what they eat and how they eat it) to achieve a sustainable diet. The two fixes found remarkably distinct perspectives over dietary politics and the ethics of food production and consumption. In this paper we argue that such polarized thinking rests on a misrepresentation of the ontological status of food, which in turn affects the underlying ethical and political issues. Food is a socially constructed object that draws in specific ways on habits, norms, traditions, geographical, and climatic conditions. Although this thesis seems somewhat obvious, its consequences on the ethical and political perspectives on the future of food have not been derived properly. After introducing the issue at stake (¤1), we point out the polarities that characterize food utopias (¤2) and their ontological faults (¤3). We hence suggest that a socio-ontological analysis of food can better deliver the principles for a foundation of food utopias (¤4). (shrink)

This paper outlines an account of conditionals, the evidential account, which rests on the idea that a conditional is true just in case its antecedent supports its consequent. As we will show, the evidential account exhibits some distinctive logical features that deserve careful consideration. On the one hand, it departs from the material reading of ‘if then’ exactly in the way we would like it to depart from that reading. On the other, it significantly differs from the non-material accounts which (...) hinge on the Ramsey Test, advocated by Adams, Stalnaker, Lewis, and others. (shrink)

The ontology of recipes is by and large unexplored. In this paper, I offer a three-steps account. After introducing some key terminology, I distinguish four main options for a theory of recipes: realism, constructivism, existentialism, and the naïve approach. Hence, I first argue that recipes are social entities whose identity depends on a process of identification, typically performed by means of a performative utterance on the part of a cook ; thus, the best theoretical framework for a theory of recipes (...) is a constructivist. Secondly, I argue that the identity of recipes can be grasped only by being suitably acquainted with the dishes that instantiate them, because of the impossibility to spell out recipes in details that would match a full-fledged dish; hence, the authority to establish the identity of a recipe rests on a process of apprenticeship. Finally, I argue that the identity of recipes and—vicariously—of the dishes that instantiate them, rest on three factors: the expertise required on the part of the cook; authenticity ; and the open-ended character of recipes.

Our aim in this paper is to employ conceptual negotiation to inform a method of rethinking defective food concepts, that is concepts that fail to suitably represent a certain food-related domain or that offer representations that run counter to the interests of their users. We begin by sorting out four dimensions of a food concept: the data upon which it rests and the methodology by which those data are gathered; the ontology that sustains it; the social acts that serve to (...) negotiate and establish the concept; and the aims and values that it fosters. We then discuss the conditions that make a food concept defective, pointing out four types of defects—fragility, polarization, incoherence, and schizophrenia—which we illustrate by means of two specific examples: local food and healthy food.

To believe that every single scientist ought to be individually engaged in ethical thinking in order for science to be responsible at a collective level may be too demanding, if not plainly unrealistic. In fact, ethical labor is typically distributed across different kinds of scientists within the scientific community. Based on the empirical data collected within the Horizon 2020 ‘RRI-Practice’ project, we propose a classification of the members of the scientific community depending on their engagement in this collective activity. Our (...) classification offers, on the one hand, a model of how the ethical aspects of science are taken into consideration by scientists and, on the other, some indications on how to institutionalize ethics in science.

The present paper is divided in two parts . In the first part we will propose Meinong’s theory of time outlined in 1899 interpreted in such a way that the subtlety of his argumentation is emphasised. In the second, we will discuss different solutions for the celebrated McTaggart’s paradox, reaching the conclusion that a theory of time suggested by the reflections of the Austrian Philosopher seems to be the most adequate perspective for tackling this problem.

This paper develops a probabilistic analysis of conditionals which hinges on a quantitative measure of evidential support. In order to spell out the interpreta- tion of ‘if’ suggested, we will compare it with two more familiar interpretations, the suppositional interpretation and the strict interpretation, within a formal framework which rests on fairly uncontroversial assumptions. As it will emerge, each of the three interpretations considered exhibits specific logical features that deserve separate consideration.

Eating local food has become a mainstream proxy for virtue and a reliable model of sustainable dieting. It suffers, nonetheless, from genuine criticisms and limitations. In this paper, we suggest theoretical amendments to reorient the local food movement and turn eating local into a robust concept—comprehensive, coherent, and inclusive, affording a firm grip over structural aspects of the food chain. We develop our argument in three parts. The first contends that ‘local’ can be said of lots of entities (e.g. whole (...) or multi-ingredient foods, recipes, menus) and that its meaning varies depending on which entities are under consideration. The second examines three dimensions of being local: the distance from the place of production; the geographical origins; the social links to consumers and producers. The third presents our robust conception of eating local, grounded on a more realistic model that accommodates for heterogeneous and complex actors. (shrink)

In this paper, we aim at rethinking the concept of obesity in a way that better captures the connection between underlying medical aspects, on the one hand, and an individual’s developmental history, on the other. Our proposal rests on the idea that obesity is not to be understood as a phenotypic trait or character; rather, obesity represents one of the many possible states of a more complex phenotypic trait that we call ‘energy metabolism.’ We argue that this apparently simple conceptual (...) shift can help solve important theoretical misconceptions regarding the genetics, epigenetics, and development of obesity. In addition, we show that our proposal can be fruitfully paired with the concept of developmental channeling of a trait, which connects to the study of the plasticity and canalization of complex traits. Finally, we discuss the potential impact of our approach on the assessment, treatment, and social narratives of obesity. (shrink)

The concept of wild food does not play a significant role in contemporary nutritional science and it is seldom regarded as a salient feature within standard dietary guidelines. The knowledge systems of wild edible taxa are indeed at risk of disappearing. However, recent scholarship in ethnobotany, field biology, and philosophy demonstrated the crucial role of wild foods for food biodiversity and food security. The knowledge of how to use and consume wild foods is not only a means to deliver high-end (...) culinary offerings, but also a way to foster alternative models of consumption. Our aim in this paper is to provide a conceptual framework for wild foods, which can account for diversified wild food ontologies. In the first section of the paper, we survey the main conception of wild foods provided in the literature, what we call the Nature View. We argue that this view falls short of capturing characteristics that are core to a sound account of wilderness in a culinary sense. In the second part of the paper, we provide the foundation for an improved model of wild food, which can countenance multiple dimensions and degrees connoting wilderness in the culinary world. In the third part of the paper we argue that thanks to a more nuanced ontological analysis, the gradient framework can serve ethnobiologists, philosophers, scientists, and policymakers to represent and negotiate theoretical conflicts on the nature of wild food.

This paper investigates the logic of reasons. Its aim is to provide an analysis of the sentences of the form ‘p is a reason for q’ that yields a coherent account of their logical properties. The idea that we will develop is that ‘p is a reason for q’ is acceptable just in case a suitably defined relation of incompatibility obtains between p and ¬q. As we will suggest, a theory of reasons based on this idea can solve three challenging (...) puzzles that concern, respectively, contraposing reasons, conflicting reasons, and supererogatory reasons, and opens a new perspective on some classical issues concerning non-deductive inferences.

In this paper we discuss the role that individual and collective acts of interpretation play in shaping a metaphysics of food. Our analysis moves from David Kaplan’s recent contention that food is always open to interpretation, and substantially expands its theoretical underpinnings by drawing on recent scholarship on food and social ontology. After setting up the terms of the discussion (§1), we suggest (§2) that the contention can be read subjectively or structurally, and that the latter can be given three (...) sub-readings. We then lay out (§3) three case studies that, we submit, any viable theory of a metaphysics of food should be able to account for. We show that one structural reading—based on the idea of negotiation—swiftly accommodates for the three case studies. We thus conclude that this reading is most promising for charting a metaphysics of food. (shrink)

Philosophers have been quarrelling for ages over the correct understanding of the identity relation and its applications, but seldom have they discussed the identity of foods, including beverages under this herd. Taking wine as a working example, the present study shows that foods call attention over unnoticed metaphysical difficulties, most importantly the role of authenticity in ascertaining the identity of an individual and the possibility of identity being determined by a collectivity of people. More in details, the paper examines the (...) relationship between a rank of wines and its specific instances, that is, on what grounds some wine is of a certain rank. A “rank of wines” here stands for wines that are identical under some respect, be it the area of production, the style, the color, the variety, and so forth. Extant wine labels are taken as the best candidates to carve out a class of wine ranks that is metaphysically prior to any other; the analysis focuses on geographic indications because of the extensive discussion they have generated, but the morals here drawn extend also to other classes of wine ranks, such as those utilized by wine experts. After some introductory remarks (§1), the case is made that the identity of wines is established through judgments of authenticity (§2). Issues of authenticity are then discussed through the special case of geographic indications (§3). Two different views on how to justify the attribution of a geographic indication are presented and criticized; those rest respectively on terroir (§3.1) and chemical composition (§3.2). The last section (§4) argues for a conventionalist view on wine identity. Distancing itself from conventionalist proposals advanced to favor industrial wine production, the view defended here ties the identity of a wine to collective expert judgments of authenticity that are based on the extensive pleasure of the product.

Epistemologists and philosophers of science have often attempted to express formally the impact of a piece of evidence on the credibility of a hypothesis. In this paper we will focus on the Bayesian approach to evidential support. We will propose a new formal treatment of the notion of degree of confirmation and we will argue that it overcomes some limitations of the currently available approaches on two grounds: (i) a theoretical analysis of the confirmation relation seen as an extension of (...) logical deduction and (ii) an empirical comparison of competing measures in an experimental inquiry concerning inductive reasoning in a probabilistic setting.

While philosophers tend to consider a single type of causal history, biologists distinguish between two kinds of causal history: evolutionary history and developmental history. This essay studies the peculiarity of development as a criterion for the individuation of biological traits and its relation to form, function, and evolution. By focusing on examples involving serial homologies and genetic reprogramming, we argue that morphology (form) and function, even when supplemented with evolutionary history, are sometimes insufficient to individuate traits. Developmental mechanisms bring in (...) a novel aspect to the business of classification—identity of process-type—according to which entities are type-identical across individuals and natural kinds in virtue of the fact that they form and develop through similar processes. These considerations bear important metaphysical implications and have potential applications in several areas of philosophy. (shrink)

There seems to be a minimal core that every theory wishing to accommodate the intuition that the future is open must contain: a denial of physical determinism (i.e. the thesis that what future states the universe will be in is implied by what states it has been in), and a denial of strong fatalism (i.e. the thesis that, at every time, what will subsequently be the case is metaphysically necessary).1 Those two requirements are often associated with the idea of an (...) objective temporal flow and the non-reality of the future. However, at least certain ways to frame the “openness” intuition do not rely on any of these. Branching Time Theory (BTT) is one such: it is compatible with the denial that time flow is objective and it is couched in a language with a (prima facie) commitment to an eternalist ontology. BTT, though, urges us to resist certain intuitions about the determinacy of future claims, which arguably do not lead either to physical determinism or to fatalism. Against BTT, supporters of the Thin Red Line Theory (TRL) argue that their position avoids determinism and fatalism, while also representing the fact that there is a future which is “special” because it is the one that will be the case. But starting with Belnap and Green 1994, some have objected to the tenability of TRL, mainly on metaphysical grounds. In particular, those argue that “positing a thin red line amounts to giving up objective indeterminism,”2 and that “has unacceptable consequences, ranging from a mistreatment of actuality to an inability to talk coherently about what would have happened had what is going to happen not taken place.”3 In this paper, we wish to reframe the..

Good chefs know the importance of maintaining sharp knives in the kitchen. What’s their secret? A well-worn Taoist allegory offers some advice. The king asks about his butcher’s impressive knifework. “Ordinary butchers,” he replied “hack their way through the animal. Thus their knife always needs sharpening. My father taught me the Taoist way. I merely lay the knife by the natural openings and let it find its own way through. Thus it never needs sharpening” (Kahn 1995, vii; see also Watson (...) 2003, 46). Plato famously employed this image as an analogy for the reality of his Forms (Phaedrus, 265e). Just like an animal, the world comes pre-divided for us. Ideally, our best theories will be those which “carve nature at its joints”. While Plato employed the “carving” metaphor to convey his views about the reality of his celebrated Forms, its most common contemporary use involves the success of science -- particularly, its success in identifying distinct kinds of things. Scientists often report discovering new kinds of things -- a new species of mammal or novel kind of fundamental particle, for example -- or uncovering more information about already familiar kinds. Moreover, we often notice considerable overlap in different approaches to classification. As Ernst Mayr put it: No naturalist would question the reality of the species he may find in his garden, whether it is a catbird, chickadee, robin, or starling. And the same is true for trees or flowering plants. Species at a given locality are almost invariably separated from each other by a distinct gap. Nothing convinced me so fully of the reality of species as the observation . . . that the Stone Age natives in the mountains of New Guinea recognize as species exactly the same entities of nature as a western scientist. (Mayr 1987, 146) Such agreement is certainly suggestive. It suggests that taxonomies are discoveries rather than mere inventions. Couple this with their utility in scientific inference and explanation and we have compelling reason for accepting the objective, independent reality of many different natural kinds of things..

This volume addresses three major themes regarding recipes: their nature and identity; their relationship to territory, producers, consumers and places of production. The first part looks at taxonomies of recipes, the relationship between recipes and their source, and how recipes have changed over time, including case studies that look at unsourced recipes through to recipes for foods that are very highly processed. The second part identifies the constitutive relationships that characterize recipes, between territory, producers, consumers, places and spaces of production. (...) The third part studies the values and norms guiding the naming, production and consumption of recipes, scrutinising the cultural appropriation of recipes, how to stake authority in claiming a recipe, and the interplay between aesthetics and ethics in recipe making. With contributors ranging across disciplines including philosophy, law and history, and including established academics such as Carolyn Korsmeyer and food writers such as Rachel Laudan this volume will be of vital importance for those looking to understand how archival material forms our understanding of eating habits and culture throughout history.

This paper outlines an account of concessive conditionals that rests on two main ideas. One is that the logical form of a sentence as used in a given context is determined by the content expressed by the sentence in that context. The other is that a coherent distinction can be drawn between a reading of ‘if’ according to which a conditional is true when its consequent holds on the supposition that its antecedent holds, and a stronger reading according to which (...) a conditional is true when its antecedent supports its consequent. As we will suggest, the logical form of concessive conditionals can be elucidated by relying on this distinction. (shrink)

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the world. In cognitive science, psychology, and medical decision making, Shannon entropy is the most prominent and most widely used model to formalize probabilistic uncertainty and the (...) reduction thereof. However, a variety of alternative entropy metrics (Hartley, Quadratic, Tsallis, Rényi, and more) are popular in the social and the natural sciences, computer science, and philosophy of science. Particular entropy measures have been predominant in particular research areas, and it is often an open issue whether these divergences emerge from different theoretical and practical goals or are merely due to historical accident. Cutting across disciplinary boundaries, we show that several entropy and entropy reduction measures arise as special cases in a unified formalism, the Sharma–Mittal framework. Using mathematical results, computer simulations, and analyses of published behavioral data, we discuss four key questions: How do various entropy models relate to each other? What insights can be obtained by considering diverse entropy models within a unified framework? What is the psychological plausibility of different entropy models? What new questions and insights for research on human information acquisition follow? Our work provides several new pathways for theoretical and empirical research, reconciling apparently conflicting approaches and empirical findings within a comprehensive and unified information-theoretic formalism.

The conjunction fallacy has been a key topic in debates on the rationality of human reasoning and its limitations. Despite extensive inquiry, however, the attempt to provide a satisfactory account of the phenomenon has proved challenging. Here we elaborate the suggestion (first discussed by Sides, Osherson, Bonini, & Viale, 2002) that in standard conjunction problems the fallacious probability judgements observed experimentally are typically guided by sound assessments of _confirmation_ relations, meant in terms of contemporary Bayesian confirmation theory. Our main formal (...) result is a confirmation-theoretic account of the conjunction fallacy, which is proven _robust_ (i.e., not depending on various alternative ways of measuring degrees of confirmation). The proposed analysis is shown distinct from contentions that the conjunction effect is in fact not a fallacy, and is compared with major competing explanations of the phenomenon, including earlier references to a confirmation-theoretic account.

We discuss the probabilistic analysis of explanatory power and prove a representation theorem for posterior ratio measures recently advocated by Schupbach and Sprenger. We then prove a representation theorem for an alternative class of measures that rely on the notion of relative probability distance. We end up endorsing the latter, as relative distance measures share the properties of posterior ratio measures that are genuinely appealing, while overcoming a feature that we consider undesirable. They also yield a telling result concerning formal (...) accounts of explanatory power versus inductive confirmation, thereby bridging our discussion to a so-called no-miracle argument. (shrink)
