In the historical context of a crisis in biological psychiatry, psychedelic drugs paired with psychotherapy are globally re-emerging in research clinics as a potential transdiagnostic therapy for treating mood disorders, addictions, and other forms of psychological distress. The treatments are poised to soon shift from clinical trials to widespread service delivery in places like Australia, North America, and Europe, which has prompted ethical questions by social scientists and bioethicists. Taking a broader view, we argue that the ethics of psychedelic therapy (...) concerns not simply how psychotherapies are different when paired with psychedelic drugs, but how psychedelic therapies shape and are shaped by different values, norms, and metaphysical commitments. Drawing from the published literature and interviews with seven psychedelic therapists working in clinical trials in the United States, Germany, Switzerland, and Australia, this article opens the black box of the treatments to consider the values and informal debates currently animating the therapies. Considering questions of patient autonomy, mechanisms of therapeutic action, and which therapies are best suited to pair with psychedelic substances, we examine the ethics of psychedelic therapy as an emergent form of life. To bring this form of life out in fuller relief, we conclude by comparing and contrasting it with ayahuasca use in Amazonian shamanism. (shrink)

Drawing from the example of Asian elephant conservation in Laos, this article primarily intends to reveal the elephantocentric vision adopted by mainstream conservation project in direction to the species. In the second part, I will present some ethnographic notes collected among local population who daily live and work with pachyderms. These notes will help in opening up a broader and more ecocentric approach of elephant conservation by highlighting links between biological and cultural diversity. By revealing the cosmo-ecological view of elephants (...) as thought locally, I will then propose an enlarged vision of elephant conservation. (shrink)

The causal view of categories assumes that categories are represented by features and their causal relations. To study the effect of causal knowledge on categorization, researchers have used Bayesian causal models. Within that framework, categorization may be viewed as dependent on a likelihood computation (i.e., the likelihood of an exemplar with a certain combination of features, given the category's causal model) or as a posterior computation (i.e., the probability that the exemplar belongs to the category, given its features). Across three (...) experiments, in combination with computational modeling, we offer evidence that categorization is better accounted for by assuming that people compute posteriors and not likelihoods, though both probabilities are closely related. This result contrasts with existing analyses of causal-based categorization, which assume that likelihood computations give a good approximation of human judgments. We also find that people are able to compute likelihoods in a closely related task that elicits judgments of consistency rather than category membership judgments. Our analyses show that people do use causal probabilistic information as prescribed by a Bayesian model but that they flexibly compute likelihoods or posteriors depending on the task. We discuss our results in relation to the relevant literature on the topic. (shrink)

This article situates actor-network theory in the history of evolutionary anthropology. In the 1980s, this attempt at explaining the social through the mediation of nonhumans received important impulses from Bruno Latour’s conversations with primatologist Shirley Strum. In a re-articulation of social evolutionism, they proposed that the utilization of objects distinguished humans from baboons and that the use of a growing number of objects set industrialized human populations apart from hunter-gatherers, enabling the formation of larger collectives. While Strum’s and Latour’s early (...) work presented baboons as almost human and suggested that we moderns had never been modern, the Anthropocene has reawakened curiosity about the original question of anthropology: how do modern humans, including modern scientists, differ from premoderns and animals? This 18th-century question is gaining new significance and urgency as we recognize our transmutation into a super-dominant species. But the answer might not lie solely in the use of more objects.

We may well be witnessing a decisive event in the history of knowledge as diversity is becoming one of the premier values of late modern societies. We seek to preserve and foster biodiversity, neurodiversity, racial diversity, ethnic diversity, gender diversity, linguistic diversity, cultural diversity, and perspectival diversity. Perspectival diversity has become the passage point through which other forms of diversity must pass to become epistemically consequential. This article examines how two of its varieties, viewpoint diversity and educational diversity, have come (...) to transform the moral economy of science. Both aim at multiplying perspectives on a given subject, but their political subtexts differ markedly. The valorization of educational diversity followed a US Supreme Court decision in 1978 that enabled universities to advance social justice, if they justified race-conscious admissions in terms of the pedagogic benefits of a more diverse student body for all. By contrast, the proponents of viewpoint diversity aim at the reform of scientific knowledge production and distribution rather than the reallocation of status and power among different social groups. We examine the political epistemology of viewpoint diversity by analyzing a controversy between social psychologists who, amid the American culture wars of the 2010s, debated how to rein in their political biases in a scientific field supposedly lacking political diversity. Out of this scientific controversy grew Heterodox Academy, an activist organization promoting viewpoint diversity in higher education. By relating and comparing viewpoint and educational diversity, we clarify what is at stake epistemically in the US-centric moral economy of diversity. (shrink)

It is usual to identify initial conditions of classical dynamical systems with mathematical real numbers. However, almost all real numbers contain an infinite amount of information. I argue that a finite volume of space can’t contain more than a finite amount of information, hence that the mathematical real numbers are not physically relevant. Moreover, a better terminology for the so-called real numbers is “random numbers”, as their series of bits are truly random. I propose an alternative classical mechanics, which is (...) empirically equivalent to classical mechanics, but uses only finite-information numbers. This alternative classical mechanics is non-deterministic, despite the use of deterministic equations, in a way similar to quantum theory. Interestingly, both alternative classical mechanics and quantum theories can be supplemented by additional variables in such a way that the supplemented theory is deterministic. Most physicists straightforwardly supplement classical theory with real numbers to which they attribute physical existence, while most physicists reject Bohmian mechanics as supplemented quantum theory, arguing that Bohmian positions have no physical reality.

In order to describe the logic of morality, "contractualist" philosophers have studied how individuals behave when they choose to follow their moral intuitions. These individuals, contractualists note, often act as if they have bargained and thus reached an agreement with others about how to distribute the benefits and burdens of mutual cooperation. Using this observation, such philosophers argue that the purpose of morality is to maximize the benefits of human interaction. The resulting "contract" analogy is both insightful and puzzling. On (...) one hand, it captures the pattern of moral intuitions, thus answering questions about human cooperation: why do humans cooperate? Why should the distribution of benefits be proportionate to each person's contribution? Why should the punishment be proportionate to the crime? Why should the rights be proportionate to the duties? On the other hand, the analogy provides a mere as-if explanation for human cooperation, saying that cooperation is "as if" people have passed a contract-but since they didn't, why should it be so? To evolutionary thinkers, the puzzle of the missing contract is immediately reminiscent of the puzzle of the missing "designer" of life-forms, a puzzle that Darwin's theory of natural selection essentially resolved. Evolutionary and contractualist theory originally intersected at the work of philosophers John Rawls and David Gauthier, who argued that moral judgments are based on a sense of fairness that has been naturally selected. In this book, Nicolas Baumard further explores the theory that morality was originally an adaptation to the biological market of cooperation, an arena in which individuals competed to be selected for cooperative interactions. In this environment, Baumard suggests, the best strategy was to treat others with impartiality and to share the costs and benefits of cooperation in a fair way, so that those who offered less than others were left out of cooperation while those who offered more were exploited by their partners. It is with this evolutionary approach that Baumard ultimately accounts for the specific structure of human morality. (shrink)

This paper offers a framework for consciousness of internal reality. Recent PET experiments are reviewed, showing partial overlap of cortical activation during self-produced actions and actions observed from other people. This overlap suggests that representations for actions may be shared by several individuals, a situation which creates a potential problem for correctly attributing an action to its agent. The neural conditions for correct agency judgments are thus assigned a key role in self/other distinction and self-consciousness. A series of behavioral experiments (...) that demonstrate, in normal subjects, the poor monitoring of action-related signals and the difficulty in recognizing self-produced actions are described. In patients presenting delusions, this difficulty dramatically increases and actions become systematically misattributed. These results point to schizophrenia and related disorders as a paradigmatic alteration of a ''Who?'' system for self-consciousness. (shrink)

This study examined the effect of the pique technique preceded by a disrupting process. Passersby in the street were asked for money, either for a common amount of change (control) or 37 cents (pique technique). In half of the cases, the requester added a disrupting sentence at the beginning of the request. Results showed that the pique technique alone and the disrupting technique alone increased compliance with the request. Adding a first disrupting sentence to the pique also increased compliance compared (...) with the other three conditions. These results support the theoretical explanation that the initial disrupting sentence associated with the pique could reduce the influence of the refusal script activated by the money request.

Las ideas filosóficas del ámbito de la actividad física suelen estar sustentadas en concepciones que trascienden la propia disciplina de estudio aludida, de modo que es importante estudiarlas en profundidad. Este ensayo tiene por objetivo comprender la interpretación de los términos movimiento humano y motricidad humana desde la mirada de tres corrientes filosóficas que han sido utilizadas por referentes de la actividad física, el deporte y la Educación Física. La primera corriente filosófica analizada es la de corte idealista, que entiende (...) el movimiento humano como un acto esencialmente mecánico y biológico. La segunda perspectiva filosófica es la materialista, que entiende el movimiento humano como una manifestación de la motricidad, la cual sería inmanente a la esencia del ser humano. Es decir, estaría dotada de intencionalidad. La tercera corriente sería una mirada ecléctica de las dos anteriores, asemejando el concepto de movimiento humano con el de las contemporáneas interpretaciones de motricidad. En otras palabras, el movimiento humano sería parte de la potencia y el acto. Se concluye que, según diferentes perspectivas filosóficas, es posible utilizar el concepto de movimiento y/o motricidad para trascender la mirada idealista o moderna del movimiento humano. (shrink)

How might a human communication system be bootstrapped in the absence of conventional language? We argue that motivated signs play an important role (i.e., signs that are linked to meaning by structural resemblance or by natural association). An experimental study is then reported in which participants try to communicate a range of pre-specified items to a partner using repeated non-linguistic vocalization, repeated gesture, or repeated non-linguistic vocalization plus gesture (but without using their existing language system). Gesture proved more effective (measured (...) by communication success) and more efficient (measured by the time taken to communicate) than non-linguistic vocalization across a range of item categories (emotion, object, and action). Combining gesture and vocalization did not improve performance beyond gesture alone. We experimentally demonstrate that gesture is a more effective means of bootstrapping a human communication system. We argue that gesture outperforms non-linguistic vocalization because it lends itself more naturally to the production of motivated signs. (shrink)

We then consider evidence for iconicity at the level (...) of the system in graphical communication and finally draw comparisons between iconicity in graphical and gestural communication systems and in spoken language.

This paper compares two explanations of the process by which human communication systems evolve: iterated learning and social collaboration. It then reports an experiment testing the social collaboration account. Participants engaged in a graphical communication task either as a member of a community, where they interacted with seven different partners drawn from the same pool, or as a member of an isolated pair, where they interacted with the same partner across the same number of games. Participants’ horizontal, pair‐wise interactions led (...) “bottom up” to the creation of an effective and efficient shared sign system in the community condition. Furthermore, the community‐evolved sign systems were as effective and efficient as the local sign systems developed by isolated pairs. Finally, and as predicted by a social collaboration account, and not by an iterated learning account, interaction was critical to the creation of shared sign systems, with different isolated pairs establishing different local sign systems and different communities establishing different global sign systems.

This paper demonstrates the central role of the Socratic elenchus in the Sophist. In the first part, I defend the position that the Stranger describes the Socratic elenchus in the sixth division of the Sophist. In the second part, I show that the Socratic elenchus is actually used when the Stranger scrutinizes the accounts of being put forward by his predecessors. In the final part, I explain the function of the Socratic elenchus in the argument of the dialogue. By contrast (...) with standard scholarly interpretations, this way of reading the text provides all the puzzles about being (241c4–251a4) with a definite function in the dialogue. It also reveals that Plato’s methodology includes a plurality of method and is more continuous than what is often believed. (shrink)

¿Es posible que el arte progrese al mismo ritmo que la filosofía racional? ¿No existe algún tipo de incompatibilidad constitutiva entre ambos modos de interpretar la realidad, de manera tal que, siempre, la mayor precisión de la última implica una menor intensidad del primero? Tales preguntas constituyeron un vital eje de preocupación para los pensadores de la Ilustración francesa. En este artículo, nos concentramos en la respuesta que Denis Diderot intenta dar al dilema. Mostramos, en primer lugar, cómo el editor (...) de la Encyclopédie diferencia ambas áreas de la producción humana a la hora de trazar su historia: si bien es necesario destacar el progreso de la razón, lo es también el reconocer la decadencia de las artes como una de sus consecuencias. En segundo lugar, mostramos cómo, elaborado este diagnóstico, Diderot procura, a través de propuestas pictóricas, poetológicas y dramatúrgicas, salvar la potencia estética del arte para un siglo ilustrado.

This book features 20 essays that explore how Latin medieval philosophers and theologians from Anselm to Buridan conceived of habitus, as well as detailed studies of the use of the concept by Augustine and of the reception of the medieval doctrines of habitus in Suàrez and Descartes. Habitus are defined as stable dispositions to act or think in a certain way. This definition was passed down to the medieval thinkers from Aristotle and, to a lesser extent, Augustine, and played a (...) key role in many of the philosophical and theological developments of the time. Written by leading experts in medieval and modern philosophy, the book offers a historical overview that examines the topic in light of recent advances in medieval cognitive psychology and medieval moral theory. Coverage includes such topics as the metaphysics of the soul, the definition of virtue and vice, and the epistemology of self-knowledge. The book also contains an introduction that is the first attempt at a comprehensive survey of the nature and function of habitus in medieval thought. The material will appeal to a wide audience of historians of philosophy and contemporary philosophers. It is relevant as much to the historian of ancient philosophy who wants to track the historical reception of Aristotelian ideas as it is to historians of modern philosophy who would like to study the progressive disappearance of the term “habitus” in the early modern period and the concepts that were substituted for it. In addition, the volume will also be of interest to contemporary philosophers open to historical perspectives in order to renew current trends in cognitive psychology, virtue epistemology, and virtue ethics.

PREFACEProf. Göran Sundholm of Leiden University inspired the group of Logic at Lille and Valparaíso to start a fundamental review of the dialogical conception of logic by linking it to constructive type logic. One of Sundholm's insights was that inference can be seen as involving an implicit interlocutor. This led to several investigations aimed at exploring the consequences of joining winning strategies to the proof-theoretical conception of meaning. The leading idea is, roughly, that while introduction rules lay down the conditions (...) under which a winning strategy for the Proponent may be built, the elimination rules lay down those elements of the Opponent's assertions that the Proponent has the right to use for building winning strategy. It is the pragmatic and ethical features of obligations and rights that naturally lead to the dialogical interpretation of natural deduction.During the Visiting Professorship of Prof. Sundholm at Lille in (2012) the group of Lille started delving into the ways of implementing Per Martin-Löf's Constructive Type Theory with the dialogical perspective. In particular, Aarne Ranta's (1988) paper, the first publication on the subject, was read and discussed during Sundholm’s seminar. The discussions strongly suggested that the game-theoretical conception of quantifiers as deploying interdependent moves provide a natural link between CTT and dialogical logic. This idea triggered several publications by the group of Lille in collaboration with Nicolas Clerbout and Juan Redmond at the University of Valparaíso, including the publication of the book (2015) by Clerbout / Rahman that provides a systematic development of this way of linking CTT and the dialogical conception of logic. However the Clerbout / Rahman book was written from the CTT perspective on dialogical logic, rather than the other way round. The present book should provide the perspective from the other side of the dialogue between the Dialogical Framework and Constructive Type Theory. The main idea of our present study is that Sundholm's (1997) notion of epistemic assumption is closely linked to the Copy-Cat Rule or Socratic Rule that distinguishes the dialogical framework from other game-theoretical approaches. One way to read the present book is as a further development of Sundholm’s extension of Austin's (1946, p. 171) remark on acts of assertion to inference. Indeed, Sundholm (2013, p. 17) gave the following forceful formulation: When I say therefore, I give others my authority for asserting the conclusion, given theirs for asserting the premisses.Per Martin-Löf, in recent lectures, have utilized the dialogical perspective on epistemic assumptions to get out of a certain circle that threatens the explanation of the notions of inference and demonstration. A demonstration may be explained as a chain of (immediate) inferences starting from no premisses. That an inference J1... Jn—————Jis valid means that the conclusion J can be made evident on the assumption that J1, …, Jn are known. The notion of epistemic assumption thus enters in the explanation of valid inference. We cannot, however, in this explanation understand 'known' in the sense of demonstrated, for then we are explaining the notion of inference in terms of demonstration, whereas demonstration has been explained in terms of inference. Martin-Löf suggests that we here understand 'known' in the sense of asserted, so that epistemic assumptions are judgements others have made, judgements for which others have taken the responsibility; that the inference is valid then means that, given that others have taken responsbility for the premisses, I can take responsibility for the conclusion:The circularity problem is this: if you define a demonstration to be a chain of immediate inferences, then you are defining demonstration in terms of inference. Now we are considering an immediate inference and we are trying to give a proper explanation of that; but, if that begins by saying: Assume that J1, …, Jn have been demonstrated – then you are clearly in trouble, because you are about to explain demonstration in terms of the notion of immediate inference, hence when you are giving an account of the notion of immediate inference, the notion of demonstration is not yet at your disposal. So, to say: Assume that J1, …, Jn have already been demonstrated, makes you accusable of trying to explain things in a circle. The solution to this circularity problem, it seems to me now, comes naturally out of this dialogical analysis. […]The solution is that the premisses here should not be assumed to be known in the qualified sense, that is, to be demonstrated, but we should simply assume that they have been asserted, which is to say that others have taken responsibility for them, and then the question for me is whether I can take responsibility for the conclusion. So, the assumption is merely that they have been asserted, not that they have been demonstrated. That seems to me to be the appropriate definition of epistemic assumption in Sundholm's sense. One of the main tenets of the present study is that the further move of relating the Socratic Rule rule with judgemental equality provides both a simpler and more direct way to implement the constructive type theoretical approach within the dialogical framework. Such a reconsideration of the Socratic Rule, roughly speaking, amounts to the following. 1.A move from P that brings-forward a play-object in order to defend an elementary proposition A can be challenged by O. 2.The answer to such a challenge, involves P bringing forward a definitional equality that expresses the fact that the play-object chosen by P copies the one O has chosen while positing A. For short, the equality expresses at the object-languaje level that the defence of P relies on the authority given to O to be able to produce the play-objects she brings forward. More generally, according to this view, a definitional equality established by P and brought forward while defending the proposition A, expresses the equality between a play-object (introduced by O) and the instruction for building a play-object deployed by O while affirming A. So it can be read as a computation rule that indicates how to compute O's instructions. Let us recall that from the strategic point of view, O's moves correspond to elimination rules of demonstrations. Thus, the dialogical rules that prescribe how to introduce a definitional equality – correspond – at the strategic level – to the definitional equality rules for CTT as applied to the selector-functions involved in the elimination rules. So, what we are doing here is extending the dialogical interpretation of Sundholm's epistemic assumption to the rules that set up the definitional equality of a type.The present work is structured in the following way:•In the Introduction we state the main tenets that guide our book•Chapter II contains a brief overview of Constructive Type Theory penned by Ansten Klev with exercises and their solutions. •Chapter III offers a novel presentation of the dialogical conception of logic.

This article argues for a novel approach to the measurement of freedom of choice, on which the availability of an option is a matter of degree, rather than a bivalent matter of being either available or not. This approach is motivated by case studies involving weakness of will, where deficiencies in willpower seem to impair individual freedom by making certain alternatives much harder to pursue. This approach is perfectly general, however: its graded analysis of option availability can be extended to (...) cases where weakness of will is not involved and can be used to generalize numerous existing measures of freedom.

We argue that two powerful error-theoretic concepts provide a general framework that satisfactorily accounts for key aspects of the explanation of physical patterns. This method gives an objective criterion to determine which mathematical models in a class of neighboring models are just as good as the exact one. The method also emphasizes that abstraction is essential for explanation and provides a precise conceptual framework that determines whether a given abstraction is explanatorily relevant and justified. Hence, it increases our epistemological understanding (...) of how one should go about reconstructing scientific practices by making clear that, at a fundamental level, a key aspect of mathematical modeling consists in exactly solving nearby problems.

Interest in the computational aspects of modeling has been steadily growing in philosophy of science. This paper aims to advance the discussion by articulating the way in which modeling and computational errors are related and by explaining the significance of error management strategies for the rational reconstruction of scientific practice. To this end, we first characterize the role and nature of modeling error in relation to a recipe for model construction known as Euler’s recipe. We then describe a general model (...) that allows us to assess the quality of numerical solutions in terms of measures of computational errors that are completely interpretable in terms of modeling error. Finally, we emphasize that this type of error analysis involves forms of perturbation analysis that go beyond the basic model-theoretical and statistical/probabilistic tools typically used to characterize the scientific method; this demands that we revise and complement our reconstructive toolbox in a way that can affect our normative image of science.

Human cognition and behavior are dominated by symbol use. This paper examines the social learning strategies that give rise to symbolic communication. Experiment 1 contrasts an individual-level account, based on observational learning and cognitive bias, with an inter-individual account, based on social coordinative learning. Participants played a referential communication game in which they tried to communicate a range of recurring meanings to a partner by drawing, but without using their conventional language. Individual-level learning, via observation and cognitive bias, was sufficient (...) to produce signs that became increasingly effective, efficient, and shared over games. However, breaking a referential precedent eliminated these benefits. The most effective, most efficient, and most shared signs arose when participants could directly interact with their partner, indicating that social coordinative learning is important to the creation of shared symbols. Experiment 2 investigated the contribution of two distinct aspects of social interaction: behavior alignment and concurrent partner feedback. Each played a complementary role in the creation of shared symbols: Behavior alignment primarily drove communication effectiveness, and partner feedback primarily drove the efficiency of the evolved signs. In conclusion, inter-individual social coordinative learning is important to the evolution of effective, efficient, and shared symbols. (shrink)

Modern mathematical sciences are hard to imagine without appeal to efficient computational algorithms. We address several conceptual problems arising from this interaction by outlining rival but complementary perspectives on mathematical tractability. More specifically, we articulate three alternative characterizations of the complexity hierarchy of mathematical problems that are themselves based on different understandings of computational constraints. These distinctions resolve the tension between epistemic contexts in which exact solutions can be found and the ones in which they cannot; however, contrary to a (...) persistent myth, we conclude that having an exact solution is not generally more epistemologically beneficial than lacking one.

Although the correlation between Entrepreneurial Orientation and concrete actions to set up a business or the Probability of Starting a Business has been widely studied, the psychological factors that can affect this relationship have not yet been sufficiently addressed in the field of entrepreneurship. One of them is curiosity. Both at theoretical and empirical level, a distinction are usually made between two types of curiosity. I-type curiosity is associated with the anticipated pleasure of discovering something new, and D-type curiosity is (...) associated with reducing uncertainty and eliminating unwanted states of ignorance. Consequently, this paper aims to analyze the moderating role that the types of curiosity play in the relationship between EO and PSB, considering their interaction with sociodemographic variables. The sample of this cross-sectional study consisted of 1,761 participants. The EO scale and a curiosity scale were applied. In addition, participants were asked, based on their perception, how likely they were to start their own business within the next 5 years. A simple moderation analysis was considered to test the moderating role of both types of curiosity in the relationship between EO and PSB. Next, a double moderation analysis was carried out in order to identify, which sociodemographic variables moderate the moderating effect of curiosity. The results show that only the D-type component moderates the relationship between EO and PSB: The higher the D-type curiosity, the stronger the association between EO and PSB. In terms of sociodemographic variables, neither culture nor gender showed a moderating effect on the moderation exerted by D-type curiosity. While, age did moderate the moderating effect of D-type curiosity on the relationship between EO and PSB. Results are discussed in terms of spirituality and the resolution of problems associated with the entrepreneurial process, considering cognitive and psychological factors, particularly with an emphasis on explaining why only D-type curiosity shows a moderating effect. Finally, the limitations of the study and potential future lines of research are pointed out. (shrink)

ABSTRACT This paper examines consequences of the computer revolution in mathematics. By comparing its repercussions with those of conceptual developments that unfolded in the nineteenth century, I argue that the key epistemological lesson to draw from the two transformative periods is that effective and successful mathematical practices in science result from integrating the computational and conceptual styles of mathematics, and not that one of the two styles of mathematical reasoning is superior. Finally, I show that the methodology deployed by applied (...) mathematicians in modern scientific computing is a paradigmatic instance of this key lesson. (shrink)

It is commonly assumed that moral deliberation requires that the alternatives available in a choice situation are evaluatively comparable. This comparability assumption is threatened by claims of incomparability, which is often established by means of the small improvement argument (SIA). In this paper I argue that SIA does not establish incomparability in a stricter sense. The reason is that it fails to distinguish incomparability from a kind of evaluative indeterminacy which may arise due to the vagueness of the evaluative comparatives (...) ‘better than,’ ‘worse than,’ and ‘equally as good as.’.

Do we interpret in the same manner the expressions 'deux pommes' and 'deux pommes et demie'? Studying their English equivalents 'two apples' and 'two and a half apples', Liebesman (2015) has recently proposed that the interpretation of both expressions involves a form of measure, distinct from simple counting. I first present Liebesman’s arguments concerning English. Then I analyze the case of French. I defend the following theses: the interpretation of 'deux pommes' does use ordinary counting with natural numbers, while the (...) interpretation of 'deux pommes et demie' involves a form of ellipsis and, in some cases, a reinterpretation of the noun 'pomme'.

Artificial intelligence and robots may progressively take a more and more prominent place in our daily environment. Interestingly, in the study of how humans perceive these artificial entities, science has mainly taken an anthropocentric perspective (i.e., how distant from humans are these agents). Considering people’s fears and expectations from robots and artificial intelligence, they tend to be simultaneously afraid and allured to them, much as they would be to the conceptualisations related to the divine entities (e.g., gods). In two experiments, (...) we investigated the proximity of representation between artificial entities (i.e., artificial intelligence and robots), divine entities and natural entities (i.e., humans and other animals) at both an explicit (Study 1) and an implicit level (Study 2). In the first study, participants evaluated these entities explicitly on positive and negative attitudes. Hierarchical clustering analysis showed that participants’ representation of artificial intelligence, robots and divine entities were similar, while the representation of humans tended to be associated with that of animals. In the second study, participants carried out a word/non-word decision task including religious semantic-related words and neutral words after the presentation of a masked prime referring to divine entities, artificial entities and natural entities (or a control prime). Results showed that after divine and artificial entity primes, participants were faster to identify religious words as words compared to neutral words arguing for a semantic activation. We conclude that people make sense of the new entities by relying on already familiar entities and in the case of artificial intelligence and robots, people appear to draw parallels to divine entities.

In a 1993 paper, I argued that empirical treatments of the epistemologyused by scientists in experimental work are too abstract in practice tocounter relativist efforts to explain the outcome of scientificcontroversies by reference to sociological forces. This was because, atthe rarefied level at which the methodology of scientists is treated byphilosophers, multiple mutually inconsistent instantiations of theprinciples described by philosophers are employed by contestingscientists. These multiple construals change within a scientificcommunity over short time frames, and these different versions ofscientific methodology (...) can determine the outcome of a controversy. Iillustrated with a comparatively detailed analysis of the methodologyused by biologists debating the existence of an entity called thebacterial mesosome between the mid-1950s and the mid-1970s. This 1993piece has drawn several critiques in the philosophical literature. Inthis present piece I respond to these critiques and argue that they failto address the core argument of the original paper, and I reflectfurther on the methodologies of philosophers of science pursuingempirical or `naturalistic' epistemology.

Despite being one of the most dependable methods used by applied mathematicians and engineers in handling complex systems, the finite element method commits variational crimes. This paper contextualizes the concept of variational crime within a broader account of mathematical practice by explaining the tradeoff between complexity and accuracy involved in the construction of numerical methods. We articulate two standards of accuracy used to determine whether inexact solutions are good enough and show that, despite violating the justificatory principles of one, the (...) finite element method nevertheless succeeds in obtaining its legitimacy from the other.

I argue that penal philosophy should focus more on our attitudes towards offenders, since these attitudes can shed new light on theories or principles of punishment (of which they are often expressions) and also play a significant role in changing the face of criminal justice. Building on Strawson’s “Freedom and Resentment,” I define attitudes as certain ways of seeing human beings that logically include or exclude various emotional, behavioral, and linguistic responses, that can be more or less natural, and over (...) which we have some degree of voluntary control. I argue that, understood in this sense, there are broadly speaking six attitudes towards offenders: the retributive, the hostile, the moralistic, the paternalistic, the merciful, and the actuarial. After presenting each of these attitudes, I sum up my analysis by focusing on the Polanski sexual abuse case. I then introduce the concept of second-order attitudes, where egalitarianism is the attitude that consists of taking the same attitude towards all offenders, and particularism is the attitude that consists of adjusting your attitude to each offender. Finally, I briefly explain why a mix of the retributive and the merciful should be our default attitude. (shrink)

We consider first-order theories of topological fields admitting a model-completion and their expansion to differential fields . We give a criterion under which the expansion still admits a model-completion which we axiomatize. It generalizes previous results due to M. Singer for ordered differential fields and of C. Michaux for valued differential fields. As a corollary, we show a transfer result for the NIP property. We also give a geometrical axiomatization of that model-completion. Then, for certain differential valued fields, we extend (...) the positive answer of Hilbert’s seventeenth problem and we prove an Ax–Kochen–Ershov theorem. Similarly, we consider first-order theories of topological fields admitting a model-companion and their expansion to differential fields, and under a similar criterion as before, we show that the expansion still admits a model-companion. This last result can be compared with those of M. Tressl: on one hand we are only dealing with a single derivation whereas he is dealing with several, on the other hand we are not restricting ourselves to definable expansions of the ring language, taking advantage of our topological context. We apply our results to fields endowed with several valuations. (shrink)

What is a uterus to a woman and to society? This article calls for a holistic reevaluation of how we perceive and what we expect from women’s uteruses. We explore the powerful and deeply rooted cultural representations of women’s uteruses as mere receptacles and the impact of such representations on biological categories, medical practices, and current policies. Considering controversies surrounding hysterectomies, cesarean sections, and uterus transplants, we elucidate ambivalent narratives that either promote an essentialist approach where the uterus is emblematic (...) of womanhood, or imply that the uterus is a dispensable organ useless outside of reproduction.

Cet article porte sur le déterminisme compatibiliste de Kazimierz Twardowski. Dans un premier temps, j’explique ce qu’est le déterminisme selon Twardowski et pourquoi il s’agit d’après lui d’une position plus probable que l’indéterminisme. Dans un deuxième temps, je présente son analyse du concept d’imputation [poczytywanie] – très proche de ce qu’on appelle en philosophie pénale la character theory of excuses – qui lui permet de concilier déterminisme et imputation. Cette analyse pose qu’un acte ne peut être imputé (à faute ou (...) à mérite) que s’il émane du caractère de l’agent. Dans un troisième temps, j’expose son analyse du concept de responsabilité. Dans un dernier temps, je montre que Twardowski penche vers l’incompatibilisme lorsqu’il est question du remords ou du sentiment de responsabilité, mais qu’il ne pense pas que cela doive nous conduire au scepticisme éthique. Cet article comporte en annexe une traduction d’une publication synthétique de Twardowski sur ce sujet. (shrink)

This article starts from a paradox and aims to solve it. On the one hand, although Drug Courts (DCs) are one of the most interesting penal innovations in recent years, running counter to the dominant retributive approach and the rival approach based on deterrence, they have surprisingly not attracted the attention of philosophers and therefore lack a solid philosophical foundation. On the other hand, although Pickard's ‘responsibility without blame’ approach looks very convincing on paper, its practical applications remain unclear outside (...) the clinical context. I argue that Pickard's approach is the theoretical framework that DCs need and that they are a compelling application of it: DCs do ascribe to participants various forms of responsibility (criminal ‘liability-responsibility’, responsibility of choice, responsibility for progress or failure, responsibility as answerability, tort liability) while striving to keep ‘affective blame’ at bay in order to help them regain their autonomy. However, I argue that some of the limitations of both this approach and DCs become apparent once we consider the ‘outer limits’ of DCs, in other words those who are terminated from DCs and those who refuse to enter DCs in the first place.

This book advances a new interpretation of Hart's penal philosophy. Positioning itself in opposition to current interpretations, the book argues that Hart does not defend a mixed theory of punishment, nor a rule-utilitarian theory of punishment, nor a liberal form of utilitarianism, nor a goal and constraint approach. Rather, it is argued, his penal philosophy is based on his moral pluralism, which comprises two aspects: value pluralism and pluralism with respect to forms of moral reason. It is held that this (...) means, on the one hand, that criminal law has an irreducible complexity due to the compromises it makes to accommodate competing values, and on the other hand, that there need not be one single justification of punishment. This original interpretation is not based only on Hart's key volume on the subject Punishment and Responsibility, but on a careful reading of his complete works. The book will be a valuable resource for academics and researchers interested in Hart's philosophy, the philosophy of law and criminal law. (shrink)
