A new theory about the origins of consciousness that finds learning to be the driving force in the evolutionary transition to basic consciousness. What marked the evolutionary transition from organisms that lacked consciousness to those with consciousness—to minimal subjective experiencing, or, as Aristotle described it, “the sensitive soul”? In this book, Simona Ginsburg and Eva Jablonka propose a new theory about the origin of consciousness that finds learning to be the driving force in the transition to basic consciousness. Using (...) a methodology similar to that used by scientists when they identified the transition from non-life to life, Ginsburg and Jablonka suggest a set of criteria, identify a marker for the transition to minimal consciousness, and explore the far-reaching biological, psychological, and philosophical implications. After presenting the historical, neurobiological, and philosophical foundations of their analysis, Ginsburg and Jablonka propose that the evolutionary marker of basic or minimal consciousness is a complex form of associative learning, which they term unlimited associative learning (UAL). UAL enables an organism to ascribe motivational value to a novel, compound, non-reflex-inducing stimulus or action, and use it as the basis for future learning. Associative learning, Ginsburg and Jablonka argue, drove the Cambrian explosion and its massive diversification of organisms. Finally, Ginsburg and Jablonka propose symbolic language as a similar type of marker for the evolutionary transition to human rationality—to Aristotle's “rational soul.”. (shrink)

The Exclusion Problem for mental causation suggests that there is a tension between the claim that the mental causes physical effects, and the claim that the mental does not overdetermine its physical effects. In response, Karen Bennett puts forward an extra necessary condition for overdetermination : if one candidate cause were to occur but the other were not to occur, the effect would still occur. She thus denies one of the assumptions of EP, the assumption that if an effect has (...) two sufficient causes, it is overdetermined. If sound, her argument does two things: it solves EP, and it shows how to use counterfactuals in order to make the notion of overdetermination precise. However, the argument is not sound. (shrink)

A number of studies have investigated glossolalia from different points of view, dealing with its various occurrences in the religious, psychopathological, and – more recently – also poetic and musical domains. The impossibility of fully understanding such a phenomenon through a purely linguistic approach has then increasingly emerged, pointing out the need to adopt a broader perspective. However, no extensive research has been developed on musical glossolalia – and especially on its non-religious forms – from such a point of view. (...) The present paper aims precisely at filling this gap: philosophical discussion of existing literature and the semiotic analysis of particularly relevant case studies of glossolalia in the musical domain help us shed new light on the functioning mechanisms of such a phenomenon, hence suggesting effective tools for understanding how it acquires meaning and produces sense.

Human migration has long been a type of adaptive response to climatic conditions and environmental pressures. However, anthropogenic climate change threatens to exacerbate vulnerabilities and impact adaptive capacity. Climate change impacts human mobility by way of long-term climate processes as well as sudden events whose intensity and frequency are exacerbated. Climate-related mobilities include the range of outcomes that result from climate change’s impacts on human mobility. The effects of climate change on human mobility are diverse. They include various types of (...) movement, including movement within borders as well as external or cross-border movement. Such mobility outcomes also include various degrees of agency in whether people can choose to move. Furthermore, climate change can impact whether humans will move more or will move less. Instances of immobility also vary with regards to agency in decision making, with some populations choosing to stay in vulnerable locations while others may be “trapped.” Vulnerability and adaptive capacity under conditions of climate change depends on the interaction of climate impacts with political social, cultural, economic, and additional factors. The heterogeneity of climate-related mobility outcomes and the difficulty in determining the scale and scope of the impact on human well-being raises a number of practical and normative challenges. The chapter examines and compares a range of normative frameworks that address the moral problem of climate change’s impacts on human mobility. These approaches articulate the nature of the moral problem, identify the rights that are violated and the associated harms of displacement, and identify correlative obligations to those who are vulnerable to climate-related impacts. The chapter concludes by suggesting further directions normative theorizing about climate-related mobilities can take considering the complex challenges the phenomena poses for the international state system.

I argue that disposition ascriptions—claims like ‘the glass is fragile’—are semantically equivalent to possibility claims: they are true when the given object manifests the disposition in at least one of the relevant possible worlds.

This article considers the claim that gender diverse minors and their families should not be able to consent to hormonal treatment for gender dysphoria. The claim refers particularly to hormonal treatment with so-called ‘blockers’, analogues that suspend temporarily pubertal development. We discuss particularly four reasons why consent may be deemed invalid in these cases: the decision is too complex; the decision-makers are too emotionally involved; the decision-makers are on a ‘conveyor belt’; the possibility of detransitioning. We examine each of these (...) reasons and we show that none of these stand up to scrutiny, and that some are based on a misunderstanding of the nature and purposes of this stage of treatment and of the circumstances in which it is usually prescribed. Moreover, accepting these claims at face value could have serious negative implications, not just for gender diverse youth, but for many other minors and families and in a much broader range of healthcare settings.

This book offers an extensive historical, philosophical and ethical discussion on the role of autonomous technologies, and their influence on human identity. By connecting those different perspectives, and analysing some practical case studies, it guides readers to dissect the relationship between machine and human autonomy, and machine and human identity. It analyses how the relationship between human and technology has been evolving in the last few centuries. Last, it aims at proposing an explanation on the reason/s why humans have been (...) keen on developing their own autonomy’s perfect avatar. (shrink)

The importance of humanities in the medical curriculum is increasingly recognized. For example, in the United Kingdom, The General Medical Council, which is an independent body established under the Medical Act 1858 and responsible, among other things, for fostering good medical practice and promoting high standards of medical education, in its publication Tomorrow’s Doctors, encouraged inclusion of humanities in the medical curriculum. Literature, arts, poetry, and philosophy are thought to foster the doctors’ ability to “communicate with patients, to penetrate more (...) deeply into the patient’s wider narrative, and to seek more diverse ways of promoting well being and reducing the impact of illness or disability.”.

The principles that usually direct ethical decision making are not easily or straightforwardly applicable to the care and treatment of anorexia nervosa, particularly the care and treatment of severe and enduring anorexia nervosa, where the sufferer seems to be recalcitrant to treatment and where the condition has become life-threatening.There are exceptional circumstances that characterize this puzzling and still scarcely understood condition; I suggest that these exceptional circumstances provide moral reasons for partial derogation from the usual principles of ethical decision making.In (...) what follows I argue...

Corporate social responsibility research has focused often on the business returns of corporate social initiatives but less on their possible social returns. We study an actual company–consumer partnership CSR initiative promoting ecologically correct and conscious consumption of bottled mineral water. We conduct a survey on adult consumers to test the hypotheses that consumer skepticism toward the company–consumer partnership CSR initiative and the moral emotion of elevation mediate the relationship between company CSR motives perceived by consumers and consumer behavioral responses following (...) this CSR initiative. Favorable consumer behavioral responses, in turn, relate positively to consumer support of other green products. The results provide scholars and managers with means of improving their understanding and handling of company–consumer partnership CSR initiatives. (shrink)

A new trend in the production technology of solid biof uels has appeared. There is a wide consensus that most solid biofuels will be produced according to the new production methods within a few years. Numerous samples were manufactured from agro-residues according to conventional methods as well as new methods. Robust analyses that reviewed the hygienic, environmental, financial and ethical aspects were performed. The hygienic and environmental aspect was assessed by robust chemical and technical analyses. The financial aspect was assessed (...) by energy cost breakdown. The ethical point of view was built on the above stated findings, the survey questionnaire and critical discussion with the literature. It is concluded that the new production methods are significantly favourable from both the hygienic and environmental points of view. Financial indicators do not allow the expressing of any preference. Regarding the ethical aspect, it is concluded that the new methods are beneficial in terms of environmental responsibility. However, it showed that most of the customers that took part in the survey are price oriented and therefore they tend to prefer the cheaper—conventional alternative. In the long term it can be assumed that expansion of the new technology and competition among manufacturers will reduce the costs. (shrink)

We continuously talk about autonomous technologies. But how can words qualifying technologies be the very same words chosen by Kant to define what is essentially human, i.e. being autonomous? The article focuses on a possible answer by reflecting upon both etymological and philosophical issues, as well as upon the case of autonomous vehicles. Most interestingly, on the one hand, we have the notion of “autonomy”, meaning that there is a “law” that is “self-given”, and, on the other hand, we have (...) the notion of “automation”, meaning that there is something “offhand” that is “self-given”. Yet, we are experiencing a kind of twofold shift: on the one hand, the shift from defining technologies in terms of automation to defining technologies in terms of autonomy and, on the other hand, the shift from defining humans in terms of autonomy to defining humans in terms of automation. From a philosophical perspective, the shift may mean that we are trying to escape precisely from what autonomy founds, i.e. individual responsibility of humans that, in the Western culture, have been defined for millennia as rational and moral decision-makers, even when their decisions have been the toughest. More precisely, the shift may mean that we are using technologies, and in particular emerging algorithmic technologies, as scapegoats that bear responsibility for us by making decisions for us. Moreover, if we consider the kind of emerging algorithmic technologies that increasingly surround us, starting from autonomous vehicles, then we may argue that we also seem to create a kind of technological divine that, by being always with us through its immanent omnipresence, omniscience, omnipotence and inscrutability, can always be our technological scapegoat freeing us from the most unbearable burden of individual responsibility resulting from individual autonomy.

Rural community organisations (RCOs) are part of a non-governmental organisations network, an effective tool for tackling local problems and reducing growing territorial exclusion. Despite their significance, it is not fully clear how many of these organisations exist in Lithuania. This is due to several reasons: the typology of settlements in the national law (more specifically, the definition of rural areas) no longer reflects the demographic reality, and the definitions contained in the sub-legislation are ‘manipulated’. In the context of the activities (...) of RCO, this is a flawed practice as it slows down the empowerment of the existing potential of organisations. The article presents the issue of the RCO network as well as addresses the problem of the typology of the settlement system itself. Adapting the research practice opens a scientific debate to launch a search for answers to emerging problems. (shrink)

A short story of an assassin and a sleeping old Fisherman: Before I explain the rationale of this anecdote, let me begin my response by saying how grateful I am to Bratton and Tomasini for engaging with me over such a thorny and unpleasant topic. Many of us have either suffered eating disorders, or have a relative or a friend who has had an eating disorder, or who has died with anorexia. I still remember giving a talk on anorexia nervosa, (...) several years ago, and at the end of the talk one senior academic was very shaken and nearly in tears. He had lost his sister with anorexia. For many of us, eating disorders are an extremely sensitive issue, and for this very reason, I feel particularly indebted when .. (shrink)

We discuss the evolutionary transition from animals with limited experiencing to animals with unlimited experiencing and basic consciousness. This transition was, we suggest, intimately linked with the evolution of associative learning and with flexible reward systems based on, and modifiable by, learning. During associative learning, new pathways relating stimuli and effects are formed within a highly integrated and continuously active nervous system. We argue that the memory traces left by such new stimulus-effect relations form dynamic, flexible, and varied global sensory (...) states, which we call categorizing sensory states . These CSSs acquired a function: they came to act as internal “evaluators” and led to positive and negative reinforcement of new behavior. They are therefore the simplest, distinct, first-person motivational states that an animal can have. They constitute what we call basic consciousness, and are the hallmark of animals that can experience. Since associative learning has been found in many invertebrate taxa that first appeared during the Cambrian era, we propose that the processes underlying basic consciousness are phylogenetically ancient, and that their emergence may have fueled the Cambrian explosion.

The tripartite model of militant extremist mind-set proposed by Stankov et al. (2010b) includes three components: War (justification of violent acts); God (extremist acts are moral because they are done in the name of God/Allah); and West (violence against Western countries is justified because they are perceived as evil). There is a lack of conceptual framework regarding psychological mechanism that underlie radicalization and extremism, and there is little evidence regarding risk factors for radicalization in the scientific literature. In the present (...) study, it is hypothesized that irrational beliefs and a constellation of personality factors are two possible psychological mechanisms that put adolescents in a vulnerable position and could influence them to develop an extremist mind-set. The sample consists in 295 Romanian adolescents, ages 15-18 years, and the mean age being 16.41. The present study was conducted in several schools from Bihor County located in the north-western part of Romania. Adolescents took part on a voluntary basis in the study after the written, informed consent was obtained from their parents. A confirmatory factor analysis (CFA) on the structure of Militant Extremist Mind-Set Scale confirmed the three-factor model of the extremist mind-set. Two confirmatory factor analyses were also conducted for the other two administered scales: CASI and Mini-IPIP. The results support the previous models for both subscales, including items loading on factors. SEM analysis was performed with AMOS 23 statistical package on a final sample size of 242 participants and there were no missing data. Fifth structural models were specified. The fifth model had adequate fit based on all three indices including the RMSEA (0.054), CFI (0.958), and SRMS (0.047). Global evaluation of self seems to be the only irrational belief that was somewhat related with the extremis mind-set, being part of it. Neuroticism was not identified as being a variable that could have a direct influence on mind-set extremism, or an indirect influence through personality. Religious adherence is a good predictor of extremist ideology. A global personality factor consisting in low Intellect/Imagination, low Extraversion and high Agreeableness seems to be a vulnerability factor that influences people to believe in extremist ideology.

This is the first of two papers in which we propose an evolutionary route for the transition from sensory processing to unlimited experiencing, or basic consciousness. We argue that although an evolutionary analysis does not provide a formal definition and set of sufficient conditions for consciousness, it can identify crucial factors and suggest what evolutionary changes enabled the transition. We believe that the raw material from which feelings were molded by natural selection was a global sensory state that we call (...) overall sensation, which is a by-product of the incessant activity of the highly interconnected nervous systems that characterize all neural animals. We argue that global sensory states generated limited experiencing once they became coupled to the simplest kinds of nervous-system-mediated learning, a coupling that occurred in the most ancient taxa of neural animals, which were similar to present-day cnidarians and ctenophores. In such animals, limited experiencing involves a small number of persistent global sensory states. These sensory states, however, do not have a function and do not act as motivational states. As we argue in the next paper, with the evolution of associative learning they evolved into systems that gave animals basic consciousness. (shrink)

Fairness is one of the most prominent values in the Ethics and Artificial Intelligence (AI) debate and, specifically, in the discussion on algorithmic decision-making (ADM). However, while the need for fairness in ADM is widely acknowledged, the very concept of fairness has not been sufficiently explored so far. Our paper aims to fill this gap and claims that an ethically informed re-definition of fairness is needed to adequately investigate fairness in ADM. To achieve our goal, after an introductory section aimed (...) at clarifying the aim and structure of the paper, in section “Fairness in algorithmic decision-making” we provide an overview of the state of the art of the discussion on fairness in ADM and show its shortcomings; in section “Fairness as an ethical value”, we pursue an ethical inquiry into the concept of fairness, drawing insights from accounts of fairness developed in moral philosophy, and define fairness as an ethical value. In particular, we argue that fairness is articulated in a distributive and socio-relational dimension; it comprises three main components: fair equality of opportunity, equal right to justification, and fair equality of relationship; these components are grounded in the need to respect persons both as persons and as particular individuals. In section “Fairness in algorithmic decision-making revised”, we analyze the implications of our redefinition of fairness as an ethical value on the discussion of fairness in ADM and show that each component of fairness has profound effects on the criteria that ADM ought to meet. Finally, in section “Concluding remarks”, we sketch some broader implications and conclude. (shrink)

This paper reviews the main hypotheses relating to the aetiology of anorexia nervosa. In particular, it focuses on family and sociological studies of anorexia.

Health Recommender Systems are promising Articial-Intelligence-based tools endowing healthy lifestyles and therapy adherence in healthcare and medicine. Among the most supported areas, it is worth mentioning active aging. However, current HRS supporting AA raise ethical challenges that still need to be properly formalized and explored. This study proposes to rethink HRS for AA through an autonomy-based ethical analysis. In particular, a brief overview of the HRS’ technical aspects allows us to shed light on the ethical risks and challenges they might (...) raise on individuals’ well-being as they age. Moreover, the study proposes a categorization, understanding, and possible preventive/mitigation actions for the elicited risks and challenges through rethinking the AI ethics core principle of autonomy. Finally, elaborating on autonomy-related ethical theories, the paper proposes an autonomy-based ethical framework and how it can foster the development of autonomy-enabling HRS for AA. (shrink)

This paper reflects on some amendments to the Declaration of Helsinki in 2008. It focuses on former paragraphs 5 (now 6) and 19 (now 17). Paragraph 5 suggested that the wellbeing of research participants should take precedence over the interests of science and society. Paragraph 6 now proposes that it should take precedence over all other interests. Paragraph 19, and the new paragraph 17, suggest that research involving the members of a disadvantaged population is only justified if the clinical trial (...) is likely to benefit them. In both cases, the recommendation is that the interests of the research subjects should prevail over the interests of third parties. This paper assesses the plausibility of these statements, and in order to do so, considers debates on the moral duty to participate in biomedical research. It is argued that, even if seen in the context of the Declaration as a whole, the statements contained in these paragraphs risk offering a misleading portrait of science and risk eroding some of the ethical principles that should form the basis of a satisfactory shared life, such as altruism and responsibility for our fellows.

Journal Name: Semiotica Issue: Ahead of print.

Simona Giordano investigates the moral concerns raised by current clinical options available for transgender and gender diverse children and adolescents. From the time young children express gender incongruent preferences and attitudes, up to the time in which older adolescents might apply for medical or surgical treatment, moral questions are likely to be asked: should children be enabled to express themselves freely inside and outside the domestic environment? What are the implications of the choices that parents might make early on? (...) How should clinicians respond to distress around sexual anatomy? Is it ethical to suspend pubertal development? What level of evidence should we seek for medications to be used in paediatric care? What are the risks and benefits of various forms of hormonal treatment? Is it ethical to defer surgical interventions till adulthood? Giordano provides a detailed ethical analysis of these and many other questions that are likely to arise at various stages of a person's life and proposes a moral formula to answer these questions, as well as others, that are likely to arise in a fast-changing landscape. Children and Gender combines a detailed ethical analysis with an accurate clinical description of gender development and available clinical pathways. (shrink)

A large part of the debate around the right to refuse life-prolonging treatment of anorexia nervosa sufferers centers on the issue of competence. Whether or not the anorexic should be allowed to refuse life-saving treatment does not depend solely or primarily on competence. It also depends on whether the anorexic’s suffering is bearable or tractable, and on the degree of involvement of the family in the therapeutic process. Anorexics could be competent to refuse lifesaving treatment (Giordano 2008). However, the anorexic’s (...) refusal of life-saving treatment should not be respected purely because it is a competent decision. In fact, anorexia has two characteristics that weaken the strength of the principle .. (shrink)

Imposing artificial feeding on people with anorexia nervosa may be unethical. This seems to be Heather Draper's suggestion in her article, ‘Anorexia Nervosa and Respecting a Refusal of Life‐Prolonging Therapy: A Limited Justification.’ Although this is an important point, I shall show that the arguments supporting this point are flawed. Draper should have made a brave claim: she should have claimed that people with anorexia nervosa, who competently decide not to be artificially fed, should be respected because everybody is entitled (...) to exercise their autonomy, not only ‘in the middle’ of their life, but also at the end of it, or when their own life is at stake, because autonomy also extends to the most difficult moments of our life, and, ultimately, ‘stretches [.*T*.*T*.] far out into the distance’ at the end of it. I explain why Draper should have made the brave claim, and why she has not made it. I conclude that a defence of people's entitlement to competently refuse artificial feeding cannot rest upon the arguments developed by Draper. Whether or not we should respect competent refusal of artificial feeding depends on the normative strength that we are ready to ascribe to the principle of autonomy, to the moral relevance that we ascribe to the circumstances in which a person's autonomy is exercised, and, perhaps, eventually, on our sense of compassion.

Magazines, leaflets, weblogs, and a variety of other media incessantly spread messages advising us on how to achieve or maintain our health or well-being. In such messages, the iconic representation of the face is predominant, and reveals an interesting phenomenon: the “face of health” seems to be unattainable as such, and is generally represented in a differential way, that is to say, by making reference to its opposite – the “face of illness”, or at least of malaise. In fact, the (...) face is crucial in the medical domain: since ancient times, face observation has played an essential role in diagnostic practices, both in Western medicine (which resorts to the concept of facies, intended as the distinctive facial expression or appearance associated with a specific medical condition, for the description of pathological states) and Eastern preventive and healing techniques (within which the so-called Mian Xiang, or ‘face reading’, is fundamental, and connects the medical sphere with other aspects such as personality, talents, and dispositions). Drawing on the semiotic analysis of relevant case studies extending from classical iconography to present-day digital mediascapes, this paper investigates the representation of the face of health (and illness) across time and space, specifically focusing on the analogies and differences between the Western and the Eastern semiosphere. To this purpose, it relies on both literature concerning the representation and understanding of the face and studies on medical sign systems and discourses. (shrink)

Socialinę raidą, socialinę kaitą ir dinamiką įvairūs autoriai interpretuoja skirtingai, bet dažniausiai vartoja šią kategoriją kaip sinonimus.

The Birth of the Philologist from the Spirit of Schopenhauer’s Philosophy. Nietzsche’s Inaugural Lecture On the Personality of Homer. This essay highlights Schopenhauer’s decisive and unexplored role in Nietzsche’s Über die Persönlichkeit Homers. Following Schopenhauer’s negative assessment of the study of history, Nietzsche criticizes F. A. Wolf’s organic systematization of the sciences of antiquity and foregrounds the aesthetic dimension of philology. Contrary to Wolf, Nietzsche believes that historical investigation is subordinate to the essential pedagogical function of philology; and only through (...) its aesthetic component can philology establish which literary works of antiquity are to be considered truly “classical.” The debate on the Homeric question after the publication of Wolf’s Prolegomena ad Homerum illustrates that philologists have paradoxically become opponents and “destroyers” of the ideal of antiquity. Nietzsche shows how a methodological approach inspired by Schopenhauer’s philosophy can revive the relationship between philology and art. Nietzsche’s arguments to counter Wolf’s thesis about the problem of Homer’s personality implicitly rest on Schopenhauer’s aesthetics. In particular, through Schopenhauer’s conception of genius, Nietzsche rehabilitates the individuality of the poetic author of the Iliad and Odyssey, even though this poet does not correspond to the one referred to as “Homer” in antiquity.

This study investigates the performance measurement systems adopted by companies to manage their social responsibility activities, a theme that remains under-researched despite the important role that these mechanisms may play in helping firms control and improve their social performance. An integrative model is developed to examine how the three fundamental drivers of corporate social strategies, i.e., business motivations, perceived stakeholder pressures, and top management’s social commitment, influence the use of social performance indicators for internal decision-making and control and how such (...) use impacts companies’ social and economic performance. The results from a survey of 97 Italian companies suggest that economic motivations and top management’s commitment are associated with a more intensive use of social performance indicators for decision-making and control, whereas perceived pressures from stakeholders do not represent a significant determinant of such use. The use of social performance indicators, in turn, is found to directly influence a firm’s social performance and, indirectly, its bottom line. (shrink)

We examine collective decision-making in a jury voting game under the unanimity rule when voters have ambiguous beliefs. Unlike in existing studies (Ellis in Theoretical Economics 11:865–895, 2016; Fabrizi et al., in: AUT Economics Working Paper, 2021; Ryan in Theory and Decision 90:543–577, 2021), the locus of ambiguity is the likelihood function (signal precision) rather than the prior. This significantly alters the properties of symmetric equilibria. While prior ambiguity may induce multiple equilibria (Fabrizi et al., in: AUT Economics Working Paper, (...) 2021; Ryan in Theory and Decision 90:543–577, 2021) we show that, under likelihood ambiguity, there exists a unique non-trivial symmetric responsive equilibrium that takes the same form as in the absence of ambiguity (Feddersen and Pesendorfer in The American Political Science Review 92:23–35, 1998). Moreover, likelihood ambiguity partially offsets the pernicious effects of pivotality on decision quality: the frequency of Type I error (convicting the innocent) is typically lower than in the absence of ambiguity.
