In The Leviathan in the state theory of Thomas Hobbes, Carl Schmitt puts forward the claim that there is a ?barely visible crack? in Hobbes's theory of the state that opened the door to liberal constitutionalism. This essay claims that Schmitt's ?thesis of the crack? is composed of two elements: first, Schmitt argues that Hobbes makes a concession to individual conscience in his discussion of miracles; second, Schmitt points out that Hobbes's individualism undermines his notion of the absolute state. As (...) Schmitt relies on an unconvincing critique of Hobbes's discourse on miracles in order to justify his more general claim against Hobbes's authoritarianism, this essay suggests that Schmitt's ?thesis of the crack? is untenable in the form that Schmitt presented it in 1938. An attempt, however, is made to salvage ?the thesis of the crack? by turning to concepts found in Schmitt's Concept of the political and in Political theology. Although Schmitt openly approved of the so?called protection/obedience principle, this essay claims that there are a number of crucial differences between Schmitt's formulation of that principle and Hobbes's own version; an examination of these differences enables us (i) to appreciate the consequences of Hobbes's individualism on his theory of the state and (ii) to shed new light on Howard Warrender's famous claim that Hobbes's sovereign is inherently weak. The essay concludes that in spite of Schmitt's fallacious formulation of the ?thesis of the crack? of 1938, his political theory affords us a rare vantage point from which we can clearly see a case against the association of Hobbes with authoritarianism.

Although organizational and situational factors have been found to predict burnout, not everyone employed at the same workplace develops it, suggesting that becoming burnt out is a complex, multifaceted phenomenon. The aim of this study was to elucidate perceptions of conscience, stress of conscience, moral sensitivity, social support and resilience among two groups of health care personnel from the same workplaces, one group on sick leave owing to medically assessed burnout (n = 20) and one group who showed no indications (...) of burnout (n = 20). The results showed that higher levels of stress of conscience, a perception of conscience as a burden, having to deaden one’s conscience in order to keep working in health care and perceiving a lack of support characterized the burnout group. Lower levels of stress of conscience, looking on life with forbearance, a perception of conscience as an asset and perceiving support from organizations and those around them (social support) characterized the non-burnout group.

In this article we present the bases for a computational theory of the cognitive processes underlying human communication. The core of the article is devoted to the analysis of the phases in which the process of comprehension of a communicative act can be logically divided: (1) literal meaning, where the reconstruction of the mental states literally expressed by the actor takes place: (2) speaker's meaning, where the partner reconstructs the communicative intentions of the actor; (3) communicative effect, where the partner (...) possibly modifies his own beliefs and intentions; (4) reaction, where the intentions for the generation of the response are produced; and (5) response, where an overt response is constructed. The model appears to be compatible with relevant facts about human behavior. Our hypothesis is that, through communication, an actor tries to exploit the motivational structures of a partner so that the desired goal is generated. A second point is that social behavior requires that cooperation be maintained at some level. In the case of communication, cooperation is, in general, pursued even when the partner does not adhere to the actor's goals, and therefore no cooperation occurs at the behavioral level. This important distinction is reflected in the two kinds of game we introduce to account for communication. The main concept implied in communication is that two agents overtly reach a situation of shared mental states. Our model deals with sharedness through two primitives: shared beliefs and communicative intentions. (shrink)

Human beings frequently attribute anthropomorphic features, motivations and behaviors to animals, artifacts, and natural phenomena. Historically, many interpretations of this attitude have been provided within different disciplines. What most interpretations have in common is distinguishing children’s manifestations of this attitude, which are considered “natural,” from adults’ occurrences, which must be explained by resorting to particular circumstances. In this article, I argue that anthropomorphism is not grounded in specific belief systems but rather in interaction. In interaction, a non-human entity assumes a (...) place that generally is attributed to a human interlocutor, which means that it is independent of the beliefs that people may have about the nature and features of the entities that are anthropomorphized. This perspective allows us to explain the problems that emerge if we consider anthropomorphism as a belief: (i) adults under certain circumstances may anthropomorphize entities even if they perfectly know that these entities have no mental life; (ii) according to the situation, the same entity may be anthropomorphized or treated as an object; (iii) there is no consistency among the entities that are anthropomorphized; (iv) there is individual variability in anthropomorphization, and this variability derives from affective states rather than from different degrees of knowledge about the entity that is anthropomorphized or greater or lesser naivety of the person who anthropomorphizes. From this perspective, anthropomorphism is a basic human attitude that begins in infants and persists throughout life. The difference between adults and children is not qualitative but rather a matter of complexity. (shrink)

Various methods have been employed to investigate different aspects of the brain activity modulation related to the performance of a cycling task. In our study we examined how functional connectivity and brain network efficiency varied during an endurance cycling task. To this purpose, we reconstructed EEG signals at source level: we computed current densities in 28 anatomical regions of interest (ROIs) through the eLORETA algorithm, then we calculated the Lagged Coherence of the 28 current density signals to define the adjacency (...) matrix. To quantify changes of functional network efficiency during an exhaustive cycling task, we computed three graph theoretical indices: local efficiency (LE), global efficiency (GE) and Density (D) in two different frequency bands, Alpha and Beta bands, that indicate alertness processes and motor binding/fatigue respectively. This analysis was conducted for six different task intervals: pre-cycling, initial, intermediate and final stages of cycling, active recovery and passive recovery. Fourteen participants performed an incremental cycling task with simultaneous EEG recording and RPE monitoring to detect participants’ exhaustion. LE remained constant during the endurance cycling task in both bands. Therefore, we speculate that fatigue processes did not affect segregated neural processing. We observed an increase of GE in the Alpha band only during cycling, that could be due to greater alertness processes and preparedness to stimuli during exercise. Conversely, although D did not change significantly over time in the Alpha band, its general reduction in the Beta bands during cycling could be interpreted within the framework of the neural efficiency hypothesis, which posits a reduced neural activity for expert/automated performances. We argue that the use of graph theoretical indices represents a clear methodological advancement in studying endurance performance. (shrink)

Research in ethical AI has made strides in quantitative expression of ethical values such as fairness, transparency, and privacy. Here we contribute to this effort by proposing a new family of metrics called “decisional value scores” (DVS). DVSs are scores assigned to a system based on whether the decisions it makes meet or fail to meet a particular standard (either individually, in total, or as a ratio or average over decisions made). Advantages of DVS include greater discrimination capacity between types (...) of ethically relevant decisions and facilitation of ethical comparisons between decisions and decision-making systems, including across different modalities (for instance: human, machine, or coupled human–machine systems). After clarifying ambiguities in the concept of “decision” itself, including the question of how to individuate the decisions made by a system, we discuss the role and meaning of “decision” in common AI and machine learning approaches such as decision trees, neural networks, SVMs, and unsupervised classifiers. We then show how DVSs may be defined for several ethical values of interest, with an extended discussion of transparency. Finally, we explore how such metrics can be applied to real decision-making systems through two case studies: evaluations of LLMs for transparency; and evaluations of criminal risk assessment tools for utility, rights violations, fairness, and transparency.

After a brief discussion of Kreisel’s notion of informal rigour and Myhill’s notion of absolute proof, Gödel’s analysis of the subject is presented. It is shown how Gödel avoids the notion of informal proof because such a use would contradict one of the senses of “formal” that Gödel wants to preserve. This Gödelian notion of “formal” is directly tied to his notion of absolute proof and to the question of the general applicability of concepts, in a way that overcomes both (...) Kreisel and Myhill’s conceptions. This paper aims to contribute to the present-day debate on informal and epistemic mathematics, focusing on what appears necessary for a better understanding of the issues at stake. (shrink)

The paper discusses ten philosophical problems in deontic logic: how to formally represent norms, when a set of norms may be termed ‘coherent’, how to deal with normative conflicts, how contraryto-duty obligations can be appropriately modeled, how dyadic deontic operators may be redefined to relate to sets of norms instead of preference relations between possible worlds, how various concepts of permission can be accommodated, how meaning postulates and counts-as conditionals can be taken into account, and how sets of norms may (...) be revised and merged. The problems are discussed from the viewpoint of input/output logic as developed by van der Torre & Makinson. We argue that norms, not ideality, should take the central position in deontic semantics, and that a semantics that represents norms, as input/output logic does, provides helpful tools for analyzing, clarifying and solving the problems of deontic logic.

This innovative aid to the study of Italian was published in 1867 by Maria Francesca Rossetti, the older sister of Dante Gabriel, William Michael and Christina. A scholar and teacher of Italian, she was later to publish A Shadow of Dante, a guide to the Divine Comedy, also reissued in the Cambridge Library Collection. Her purpose here, as she explains in her preface, is to demonstrate idiomatic Italian usage by providing short passages translated very literally into English, so that (...) the 'unnatural' English phraseology demonstrates the correct Italian construction. The passages are to be translated back into Italian, with the help of some supplied vocabulary and an opening chapter which elucidates some of the more difficult aspects of Italian grammar, often by comparing Italian with French usage. The technique had long been used for Latin and Greek prose composition, but was innovatory for modern languages. (shrink)

Philosophy is often taken to be something that is always possible, so that everyone is fully entitled sketching a ‘philosophy’ of his/her own. Nevertheless, it is widely assumed that philosophy began in Miletus with Thales. But it is equally well known that the Presocratics remained unaware of being philosophers, and therefore could not even have wanted to be identified that way. These three points are not mutually compatible. So, what lies behind them? What is escaping our attention when we state (...) them? Probably an event in Plato’s life that has too often gone unnoticed: the key role he played in giving form and substance to philosophy, and in getting it to take root once and for all. Failure to acknowledge how, when, and on whose initiative philosophy came to occupy a very important place in Western culture and education for two and a half millennia; not including a note on this process in biographies of Plato; and overlooking another key event that probably occurred about 350-45 BC - these are just some of the unwelcome effects linked to the usual silence about the period in which philosophy took form.

The Ostrogorski paradox and the discursive dilemma are seemingly unrelated paradoxes of aggregation. The former is discussed in traditional social choice theory, while the latter is at the core of the new literature on judgment aggregation. Both paradoxes arise when, in a group, each individual consistently makes a judgment, or expresses a preference, (in the form of yes or no) over specific propositions, and the collective outcome is in some respect inconsistent. While the result is logically inconsistent in the case (...) of the discursive paradox, it is not stable with respect to the level of aggregation in the case of the Ostrogorski paradox. In the following I argue that, despite these differences, the two problems have a similar structure. My conclusion will be twofold: on the one hand, the similarities between the paradoxes support the claim that these problems should be tackled using the same aggregation procedure; on the other hand, applying the same procedure to these paradoxes will help clarify the strengths and weaknesses of the aggregation method itself. More specifically, I will show that an operator defined in artificial intelligence to merge belief bases can deal with both paradoxes. (shrink)

The Affective grounding hypothesis suggests that affective experiences play a crucial role in abstract concepts’ processing (Kousta et al. 2011). Vigliocco and colleagues test the role of affective experiences as well as the role of language in learning words denoting abstract concepts, comparing children with typical and atypical development. They conclude that besides the affective experiences also language plays a critical role in the processing of words referring to abstract concepts.

The aggregation of individual judgments on logically interconnected propositions into a collective decision on the same propositions is called judgment aggregation. Literature in social choice and political theory has claimed that judgment aggregation raises serious concerns. For example, consider a set of premises and a conclusion where the latter is logically equivalent to the former. When majority voting is applied to some propositions (the premises) it may give a different outcome than majority voting applied to another set of propositions (the (...) conclusion). This problem is known as the discursive dilemma (or paradox). The discursive dilemma is a serious problem since it is not clear whether a collective outcome exists in these cases, and if it does, what it is like. Moreover, the two suggested escape-routes from the paradox—the so-called premise-based procedure and the conclusion-based procedure—are not, as I will show, satisfactory methods for group decision-making. In this paper I introduce a new aggregation procedure inspired by an operator defined in artificial intelligence in order to merge belief bases. The result is that we do not need to worry about paradoxical outcomes, since these arise only when inconsistent collective judgments are not ruled out from the set of possible solutions. (shrink)

Structured argumentation formalisms, such as ASPIC +, offer a formal model of defeasible reasoning. Usually such formalisms are highly parametrized and modular in order to provide a unifying framework in which different forms of reasoning can be expressed. This generality comes at the price that, in their most general form, formalisms such as ASPIC + do not satisfy important rationality postulates, such as non-interference. Similarly, links to other forms of knowledge representation, such as reasoning with maximal consistent sets of rules, (...) are insufficiently studied for ASPIC + although such links have been established for other, less complex forms of structured argumentation where defeasible rules are absent. Clearly, for a formal model of defeasible reasoning it is important to understand for which range of parameters the formalism (a) displays a behavior that adheres to common standards of consistency, logical closure and logical relevance and (b) can be adequately described in terms of other well-known forms of knowledge representation. In this paper we answer this question positively for a fragment of ASPIC + without the attack form undercut by showing that it satisfies all standard rationality postulates of structured argumentation under stable and preferred semantics and is adequate for reasoning with maximal consistent sets of defeasible rules. The study is general in that we do not impose any other requirements on the strict rules than to be contrapositable and propositional and in that we also consider priorities among defeasible rules, as long as they are ordered by a total preorder and lifted by weakest link. In this way we generalize previous similar results for other structured argumentation frameworks and so shed further light on the close relations between assumption-based argumentation and ASPIC +.

Ethical dilemmas in critical care may cause healthcare practitioners to experience moral distress: incoherence between what one believes to be best and what occurs. Given that paediatric decision-making typically involves parents, we propose that parents can also experience moral distress when faced with making value-laden decisions in the neonatal intensive care unit. We propose a new concept—that parents may experience “moral schism”—a genuine uncertainty regarding a value-based decision that is accompanied by emotional distress. Schism, unlike moral distress, is not caused (...) by barriers to making and executing a decision that is deemed to be best by the decision-makers but rather an encounter of significant internal struggle. We explore factors that appear to contribute to both moral distress and “moral schism” for parents: the degree of available support, a sense of coherence of the situation, and a sense of responsibility. We propose that moral schism is an underappreciated concept that needs to be explicated and may be more prevalent than moral distress when exploring decision-making experiences for parents. We also suggest actions of healthcare providers that may help minimize parental “moral schism” and moral distress. (shrink)

Emotion-processing impairment represents a risk factor for the development of somatic illness, affecting negatively both health-related quality of life and disease management in several chronic diseases. The present pilot study aims at investigating the associations between alexithymia and depression, anxiety, and HRQoL in patients with Hashimoto’s thyroiditis ; examining the association between these three psychological conditions together with HRQoL, and thyroid autoantibodies status as well as thyroid echotexture in patients with HT; and comparing the intensity of all these clinical psychological (...) features in patients with HT versus controls. Twenty-one patients with serologically or ultrasonographically verified HT and 16 controls with non-toxic goiter or postsurgical hypothyroidism were recruited for this study. Serum thyrotropin and free thyroxine, as well as thyroid autoantibodies, were assayed. Alexithymia, depression, anxiety, and HRQoL were assessed with Toronto Alexithymia Scale; Beck Depression Inventory, second edition; Hamilton Anxiety Rating Scale; and Health Survey Short-Form 36, respectively. A negative relationship between the difficulty to describe feelings and the cognitive component of depression was found. Besides, patients with seronegative HT had lower somatic anxiety than patients with HT who tested positive. Besides, no statistically significant difference was found between patients with HT and controls with regard to somatic anxiety. The present study suggests the relevance of alexithymia in patients suffering from HT, which may be intertwined with a possible state of underreported depression that is mainly expressed through physical complaints. Promoting the capability to describe and communicate feelings could contribute to psychological elaboration and coping with the disease and, consequently, to the improvement of self-management and perceived HRQoL.

Thorough a detailed analysis of version III of Gödel's Is mathematics syntax of language?, we propose a new interpretation of Gödel's criticism against the conventionalist point of view in mathematics. When one reads carefully Gödel's text, it brings out that, contrary to the opinion of some commentators, Gödel did not overlook the novelty of Carnap's solution, and did not criticise him from an old-fashioned conception of science. The general aim of our analysis is to restate the Carnap/Gödel debate in the (...) Fregean heritage. We stress the way both of them try to answer, from different Fregean perspectives, to the question of the nature of logic and mathematics in knowledge. (shrink)

Judgment aggregation studies how individual opinions on a given set of propositions can be aggregated to form a consistent group judgment on the same propositions. Despite the simplicity of the problem, seemingly natural aggregation procedures fail to return consistent collective outcomes, leading to what is now known as the doctrinal paradox. The first occurrences of the paradox were discovered in the legal realm. However, the interest of judgment aggregation is much broader and extends to political philosophy, epistemology, social choice theory, (...) and computer science. The aim of this paper is to provide a concise survey of the discipline and to outline some of the most pressing questions and future lines of research. (shrink)

Au Moyen Âge, la théorie médicale de la complexio n’est pas confinée dans le domaine restreint de la théorie ou de la pratique de la médecine. Elle implique une anthropologie déterminée, qui ne concerne pas seulement la santé et le bien-être de l’homme, mais, dans certaines limites, la nature même de celui-ci ou, pour mieux dire, la manière dont la nature spécifique de l’homme s’articule avec la variété et la différence des tempéraments et des dispositions individuelles : ce qu’est chaque (...) individu dépend de la complexion qui lui est propre. Cette anthropologie médicale dépasse les limites de sa discipline et pénètre aussi la théologie, par une série d’implications, pas toujours prévisibles, qui concernent la place de l’homme dans l’univers, l’eschatologie, la démonologie et aussi la christologie. Le but de cette étude est de rendre compte de certaines de ces implications en regard de la pensée de Thomas d’Aquin. Les différents lieux où Thomas étudie la complexion corporelle – il en considère les implications dans les domaines intellectuel et moral – montrent une sorte d’assimilation de l’anthropologie médicale (indirectement galénique, mais surtout avicennienne) à l’intérieur de son horizon de pensée, constitué par la philosophie naturelle aristotélicienne et par les exigences propres à sa théologie.

Hobbes's philosophical discourse is deconstructed as the interplay of the drama of individual behavior as perceived by rational agents and the detached analysis of conflict a by a political geometer . The author solves some long-standing problems in Hobbesian political philosophy (e.g., the role of glory, Hobbes' pessimism) and shows the consistency of Hobbes's attempt to derive absolutism as the only stable political association.

Why is it that the laws of war, or international humanitarian law (IHL), allow no justification for breaking the law even if where such conduct would actually produce less humanitarian harm than following the law? In introducing the concept of a humanitarian necessity justification, and complementing existing work on humanitarian exceptions to the jus ad bellum, this paper suggests that it should. It first addresses the puzzle of IHL's existing absolutist stance with regard to compliance with IHL norms; to demonstrate (...) the implications of this absolutist stance, I use three historical case studies in which actors broke the law under a claim of necessity, or a mixed concern for self and others: The Early Warning Procedure employed by the IDF in the West Bank, the paradigmatic case of interrogational torture, and the atomic bombings of Hiroshima and Nagasaki. I then examine whether the domestic necessity defense in criminal law might be transposed onto the international level, ultimately finding that such transposition is impossible given the different assumptions that operate in domestic criminal law and IHL. In further searching for an account for IHL's absolutist stance and the possibility of mitigating that stance, the paper turns to first-order accounts - deontological, consequential, and institutional. I argue that none of these accounts offers a sufficiently convincing explanation for the exclusion of a humanitarian necessity paradigm, and instead, that room should be made for some humanitarian-driven exceptions. Ultimately, the paper offers a blueprint for a definition for a humanitarian necessity justification that would exculpate an actor who violated the laws of war in the name of a greater humanitarian good. The central component of the definition is a requirement that the greater humanitarian good would be for the benefit of the enemy, rather than for oneself. Under such paradigm, the Early Warning Procedure and perhaps even the atomic bombing of Hiroshima (but not Nagasaki) might be justified, while the paradigmatic case of interrogational torture could not.

Lewis’ Principal Principle (PP) aims at clarifying the connection between chance (i.e. objective probability) and credence (i.e. subjective probability). It is generally assumed that the chance that an event will occur does not depend on our credence in the occurrence of that event. Nevertheless, chances constrain our credence, and Lewis’ PP is an attempt to capture this connection.

The problem of the aggregation of inputs coming from different sources arises in several contexts. Examples are the combination of individual preferences (studied in social choice theory), opinions (judgment aggregation), and data (artificial intelligence). While a number of results are available in each of these disciplines, a question that has been addressed only recently is how similar these aggregation problems are, despite the different types of inputs they try to combine.

Walter Kohan has recently observed that Socrates does not seem partic­ularly interested in the opinions of his interlocutors. Consequently, the philosopher is not really involved in a peer to peer relation with them, but rather embarks upon the task of annihilating their ideas. With the situation being as it is, the image of Socrates as a champion of dialogue begins to wobble. While the present paper aims to discuss these claims, a number of issues needs to be accounted for. First (...) of all, the Socratic dialogue does begin in a characteristically symmetrical way, but it becomes more and more asymmetric as the elenchos begins to appear. This is due to the fact the elenchos makes the interlocutors defensive, whereas Socrates can attack freely. Given that, Kohan’s claims seem justified and enlightening, but they should not be regarded as conclusive, since one must neither forget nor undervalue how innovative it was to replace monologue speeches with one-to-one dialogues which offered the opportunity of being involved in unforeseeable conversations.

Thales the Measurer offers a comprehensive and iconoclastic account of Thales of Miletus, considering the full extent of our evidence to build a new picture of his intellectual interests and activity. Thales is most commonly associated with the claim that 'everything is water', but closer examination of the evidence that we have suggests that he could not have said anything of the sort. His real interests, and his real innovations, lay in challenges of quantitative measurement, especially measurements related to the (...) movement of the sun. In this he had no predecessors - and, for centuries to follow, no real successors either. This book is of interest for scholars in the history of philosophy, science, and life sciences. It is aimed especially at researchers in the field, but is also accessible to students and a more general readership. (shrink)
