The article attempts to verify that inappropriate use of information provided by the media can increase risks for persons who are susceptible to mental illness. The impact of Colombian news in 2014 related to the word suicide was studied to that end. The news was analyzed subsequently through a survey with eight questions applied by two members of the group who had been trained to conduct the study. The idea was to delve deeper and to see the effect of the (...) media and its stigmatization. Nowadays, adolescents are more exposed to situations in which their mood can be affected by improper use of the media, bearing in mind that the worst outcome would be that it leads to suicidal behavior.

ObjectiveTo investigate the association of pre-existing migraine in patients hospitalised and who recovered from severe acute respiratory syndrome coronavirus 2 infection with the presence of post-coronavirus disease symptoms.BackgroundNo study has investigated the role of migraine as a risk factor for development of post-COVID symptoms.MethodsA case-control study including individuals hospitalised during the first wave of the pandemic was conducted. Patients with confirmed previous diagnosis of migraine were considered cases. Two age- and sex-matched individuals without a history of headache per case were (...) also recruited as controls. Hospitalisation/clinical data were collected from hospital medical records. Patients were scheduled for a telephone interview. A list of post-COVID symptoms was systematically evaluated, but participants were invited to freely report any symptom. The Hospital Anxiety and Depression Scale and the Pittsburgh Sleep Quality Index were used to assess anxiety/depressive symptoms and sleep quality. Multivariable conditional logistic regression models were constructed.ResultsOverall, 57 patients with confirmed diagnosis of migraine and 144 non-migraine controls who had recovered from COVID-19 were assessed at 7.3 months after hospital discharge. The number of post-COVID symptoms in the migraine group was significantly greater than in the non-migraine group. Fatigue was significantly more prevalent in the migraine group. However, no between-groups difference in the prevalence of headache as a post-COVID symptom was detected.ConclusionPatients with a history of migraine who recovered from COVID-19 exhibited more long-term fatigue as post-COVID sequelae than those without migraine. Some of the pathophysiological changes associated with migraine could predispose to the occurrence of post-COVID symptoms. (shrink)

From the perspective of Cartesian doubt, this article explores the concept of the limitations of reasoning through the use of the Kantian words 'boundary' and 'barrier' in his Critique of Pure Reason. Hegel's critical dialogue with Kant is presented focusing on the limitation that the latter imposed on reason for the acquisition of the true knowledge of philosophical/metaphysical objects. For this purpose, the Hegelian position is presented from its discussion on the second chapter of the first section of the The (...) Doctrine of Being and references are made to conceptual elements of the Phenomenology of Spirit. (shrink)

This book offers a critical examination of those theories and advances a new argument for punishment's justification, calling it the 'duty view'.

The Criminalization series arose from an interdisciplinary investigation into criminalization, focussing on the principles that might guide decisions about what kinds of conduct should be criminalized, and the forms that criminalization should take. Developing a normative theory of criminalization, the series tackles the key questions at the heart of the issue: what principles and goals should guide legislators in deciding what to criminalize? How should criminal wrongs be classified and differentiated? How should law enforcement officials apply the law's specifications of (...) offences? The sixth volume in the series offers a philosophical investigation of the relationship between moral wrongdoing and criminalization. Considering the justification of punishment, the nature of harm, the importance of autonomy, inchoate wrongdoing, the role of consent, and the role of the state, the book provides an account of the nature of moral wrongdoing, the sources of wrongdoing, why wrongdoing is the central target of the criminal law, and the ways in which criminalization of non-wrongful conduct might be permissible.

Aristotle's discussion of perceiving that we perceive has points of contact with two contemporary debates about consciousness: the first over whether consciousness is an intrinsic feature of mental states or a higher-order thought or perception; the second concerning the qualitative nature of experience. In both cases, Aristotle's views cut down the middle of an apparent dichotomy, in a way that does justice to each set of intuitions, while avoiding their attendant difficulties. With regard to the first issue?the primary focus of (...) this paper?he argues that consciousness is both intrinsic and higher-order, due to its reflexive nature. This, in turn, has consequences for the second issue, where again Aristotle seeks out the middle ground. He is committed against qualia in any strong sense of the term. Yet he also holds that the phenomenal quality of experience is not exhausted by its representational content. (shrink)

A review of research with chicks, songbirds, rodents, and nonhuman primates indicates that the brain is lateralized for a number of behavioral functions. These findings can be understood in terms of three hypothetical brain processes derived from a brain model based on general systems theory: hemispheric activation, interhemispheric inhibition, and interhemispheric coupling.Left-hemisphere activation occurs in songbirds and nonhuman primates in response to salient auditory or visual input, or when a communicative output is required. The right hemisphere is activated in rats (...) when spatial performance is required, and in chicks when they are placed in an emotion-provoking situation. In rats and chicks interhemispheric activation and inhibition occur when there is an affective component in the environment (novelty, aversive conditioning) or when an emotional response is emitted (copulation, attack, killing). An interhemispheric coupling (correlation) found in rats and rabbits implies that the hemispheres are two major components in a control system with a negative feedback loop. Early-experience variables in rats can induce laterality in a symmetric brain or facilitate its development in an already biased brain.It is predicted that functional lateralization, when present, will be similar across species: the left hemisphere will tend to be involved in communicative functions while the right hemisphere will respond to spatial and affective information; both hemispheres will often interact via activation-inhibition mechanisms when affective or emotional processes are involved. Homologous brain areas and their connecting callosal fibers must be intact at birth and must remain intact throughout development for lateralization to reach its maximum level. Injury to any portion of this unit will result in hemispheric redundancy rather than specialization. One major function of early experience is to provide stimulation during development, which acts to enhance the growth and development of the corpus callosum, thereby giving rise to a more specialized brain.

Many philosophers endorse the Transparency Thesis, the claim that by introspection one cannot become aware of one's experience. Recently, some authors have suggested that the Transparency Thesis is challenged by introspective states reached under mindfulness. We label this the Mindfulness Opacity Hypothesis. The present paper develops the hypothesis in important new ways. First, we motivate the hypothesis by drawing on recent clinical psychology and cognitive science of mindfulness. Secondly, we develop the hypothesis by describing the implied shift in experiential perspective, (...) the scope of introspectable qualities, and the level of skill. Thirdly, we defend the hypothesis against various philosophical arguments. We conclude that the Mindfulness Opacity Hypothesis is empirically and theoretically well motivated and supported. (shrink)

Experimental research in moral psychology can be used to generate debunking arguments in ethics. Specifically, research can indicate that we draw a moral distinction on the basis of a morally irrelevant difference. We develop this naturalistic approach by examining a recent debate between Joshua Greene and Selim Berker. We argue that Greene's research, if accurate, undermines attempts to reconcile opposing judgments about trolley cases, but that his attempt to debunk deontology fails. We then draw some general lessons about the possibility (...) of empirical debunking arguments in ethics. (shrink)

In resultant moral luck, blame and punishment seem intuitively to depend on downstream effects of a person’s action that are beyond his or her control. Some skeptics argue that we should override our intuitions about moral luck and reform our practices. Other skeptics attempt to explain away apparent cases of moral luck as epistemic artifacts. I argue, to the contrary, that moral luck is real—that people are genuinely responsible for some things beyond their control. A partially consequentialist theory of responsibility (...) justifies moral luck. But this justification is no mere rationalization of the status quo. Recent experimental and evolutionary work on punishment and learning suggests that the very same reasons that justify moral luck have also shaped the evolution of our luck-sensitive moral practices.

This paper provides a philosophical analysis of the Price equation and its role in evolutionary theory. Traditional models in population genetics postulate simplifying assumptions in order to make the models mathematically tractable. On the contrary, the Price equation implies a very specific way of theorizing, starting with assumptions that we think are true and then deriving from them the mathematical rules of the system. I argue that the Price equation is a generalization-sketch, whose main purpose is to provide a unifying (...) framework for researchers, helping them to develop specific models. The Price equation plays this role because, like other scientific principles, shows features as abstractness, unification and invariance. By underwriting this special role for the Price equation some recent disputes about it could be diverted. (shrink)

Do psychopaths make moral judgments but lack motivation? Or are psychopaths’ judgments are not genuinely moral? Both sides of this debate seem to assume either externalist or internalist criteria for the presence of moral judgment. However, if moral judgment is a natural kind, we can arrive at a theory-neutral criterion for moral judgment. A leading naturalistic criterion suggests that psychopaths have an impaired capacity for moral judgment; the capacity is neither fully present nor fully absent. Psychopaths are therefore not counterexamples (...) to internalism. Nonetheless, internalism is empirically problematic because it is unable to explain psychopaths’ moral deficits. (shrink)

The long‐standing issue of Wittgenstein's controversial remarks on Gödel's Theorem has recently heated up in a number of different and interesting directions [, , ]. In their , Juliet Floyd and Hilary Putnam purport to argue that Wittgenstein's‘notorious’ “Contains a philosophical claim of great interest,” namely, “if one assumed. that →P is provable in Russell's system one should… give up the “translation” of P by the English sentence ‘P is not provable’,” because if ωP is provable in PM, PM is (...) ω ‐inconsistent, and if PM is ω‐inconsistent, we cannot translate ‘P’as ’P is not provable in PM’because the predicate‘NaturalNo.’in ‘P’“cannot be…interpreted” as “x is a natural number.” Though Floyd and Putnam do not clearly distinguish the two tasks, they also argue for “The Floyd‐Putnam Thesis,” namely, that in the 1930's Wittgenstein had a particular understanding of Gödel's First Incompleteness Theorem. In this paper, I endeavour to show, first, that the most natural and most defensible interpretation of Wittgenstein's and the rest of is incompatible with the Floyd‐Putnam attribution and, second, that evidence from Wittgenstein's Nachla strongly indicates that the Floyd‐ Putnam attribution and the Floyd‐Putnam Thesis are false. By way of this examination, we shall see that despite a failure to properly understand Gödel's proof—perhaps because, as Kreisel says, Wittgenstein did not read Gödel's 1931 paper prior to 1942‐Wittgenstein's 1937–38, 1941 and 1944 remarks indicate that Gödel's result makes no sense from Wittgenstein's own perspective.

The concept of vulnerability is widely used in bioethics, particularly in research ethics and public health ethics. The traditional approach construes vulnerability as inherent in individuals or the groups to which they belong and views vulnerability as requiring special protections. Florencia Luna and other bioethicists continue to challenge traditional ways of conceptualizing and applying the term. Luna began proposing a layered approach to this concept and recently extended this proposal to offer two new concepts to analyze the concept of vulnerability, (...) namely understanding external conditions that trigger vulnerability and layers of vulnerability with cascading effects. Luna's conception of vulnerability is useful, which we demonstrate by applying her layered view and the new analyses in multiple contexts. We begin by outlining Luna's view and we use vignettes from healthcare involving transgender patients, the care of patients in psychiatric contexts, and research involving prisoners to illustrate how each part of Luna's concept elucidates important moral issues.

From virtue ethics and interactionist perspectives, we hypothesized that personal justice norms (distributive and procedural justice norms) were shaped directly and multiplicatively by ethical dispositions (equity sensitivity and need for structure) and ethical climates (egoistic, benevolent, and principle climates). We collected multisource data from 123 companies in Hong Kong, with personal factors assessed by participants’ self-reports and contextual factors by aggregations of their peers. In general, LISREL analyses with latent product variables supported the direct and multiplicative relationships. Our findings could (...) lay the groundwork for justice research from a morality perspective in future. (shrink)

Consider the Unshareability View, namely, the view that first person thought or self-thought—thought as typically expressed via the first person pronoun—is not shareable from subject to subject. In this article, I show that a significant number of Fregean and non-Fregean commentators of Frege have taken the Unshareability View to be the default Fregean position, rehearse Frege’s chief claims about self-thought and suggest that their combination entails the Unshareability View only on the assumption that there is a one-to-one correspondence between way (...) of thinking and thought-individuating cognitive value, outline an account of self-thought that rejects the assumption and keeps intact all of Frege’s chief claims, and respond to a number of worries to the effect that this proposal yields undesirable results from the point of view of the individuation of self-thought at the level of cognitive value.

This chapter critically examines various proposals for liability of a person to defensive harm. Drawing on the idea that there is an important relationship between a person’s liability to be harmed and the enforceable duties that she incurs as a result of posing a threat to others, it demonstrates that no simple account of liability will be successful. As there are many considerations that bear on the duties that a person has, there are many considerations which bear on a person’s (...) liability to be harmed. This general claim is supported through a demonstration both that culpability without causation can ground liability, and that causal contribution without culpability can ground liability. (shrink)

Background: Caregivers and administrators in long-term facilities have fragile moral work in caring for residents with dementia. Residents are susceptible to barriers and vulnerabilities associated with the most intimate aspects of their lives, including how they express themselves sexually. The conditions for sexual agency are directly affected by caregivers’ perceptions and attitudes, as well as facility policies. Objective: This article aims to clarify how to approach capacity determinations as it relates to sexual activity, propose how to theorize about patient autonomy (...) in this context, and suggest some considerations for finding an ethically responsible and practically feasible way to respect the sexual rights of this population. Research Design: The focus is on residents with early to moderate dementia in states of daily dependency on professional caregivers. The article critically examines existing empirical research on sexuality among persons with dementia, caregivers’ attitudes, and institutional roadblocks to enabling residents’ sexuality. A relational lens and insights from disability studies are used in the philosophical analysis. Participants and Research Context: No research participants were part of this analysis. Ethical Considerations: This article offers a conceptual analysis and normative framework only. Findings: The analysis highlights the delicate balance that capacity assessments for sexual activity have to strike; while caregivers should protect those who cannot give adequate consent, the denial of sexuality among residents can cause deep, long-ranging harms. Sexual agency features into an ongoing sense of self for many individuals with dementia, and the imposition of inappropriate standards and expectations for sexual autonomy can lead to unwarranted obstacles to sexual activity. Discussion: Recommendations include developing clear and inclusive institutional policies and practices of care, providing education for caregivers on how to discuss and document residents’ sexual preferences over time, and taking advantage of ethics consultation services. Conclusion: This analysis establishes the need for more research and discussion on this sensitive topic. Future research should investigate the specific responsibilities of caregivers in furthering the sexual interests of residents, how exactly to modify existing capacity instruments, and how best to support historically marginalized patients in their sexual identities.

Scriven’s paradox of predictability arises from the combination of two ideas: first, that everything in a deterministic universe is, in principle, predictable; second, that it is possible to create a system that falsifies any prediction that is made of it. Recently, the paradox has been used by Rummens and Cuypers to argue that there is a fundamental difference between embedded and external predictors; and by Ismael to argue against a governing conception of laws. The present paper defends a new diagnosis (...) of the roots of the paradox. First, it is argued that the unpredictability has to be understood in the light of Turing’s famous results about computability, in particular his proof that there is no solution to the ‘halting problem.’ This allows us to see that previous analyses of the paradox were either mistaken or not fully adequate. Second, the sense of paradox that nevertheless remains is traced to the idea that rational behaviour is not dependent on contingent environmental circumstances: that it is always up to us to engage in activities such as rational prediction or rational belief. The paradox of predictability teaches us that this idea, natural though it may be, is mistaken. (shrink)

This book offers new essays exploring concepts and applications of nonideal theory in bioethics. Nonideal theory refers to an analytic approach to moral and political philosophy (especially in relation to justice), according to which we should not assume that there will be perfect compliance with principles, that there will be favorable circumstances for just institutions and right action, or that reasoners are capable of being impartial. Nonideal theory takes the world as it actually is, in all of its imperfections. Bioethicists (...) have called for greater attention to how nonideal theory can serve as a guide in the messy realities they face daily. Although many bioethicists implicitly assume nonideal theory in their work, there is the need for more explicit engagement with this theoretical outlook. A nonideal approach to bioethics would start by examining the sociopolitical realities of healthcare and the embeddedness of moral actors in those realities. How are bioethicists to navigate systemic injustices when completing research, giving guidance for patient care, and contributing to medical and public health policies? When there are no good options and when moral agents are enmeshed in their sociopolitical viewpoints, how should moral theorizing proceed? What do bioethical issues and principles look like from the perspective of historically marginalized persons? These are just a few of the questions that motivate nonideal theory within bioethics. This book begins in Part I with an overview of the foundational tenets of nonideal theory, what nonideal theory can offer bioethics, and why it may be preferable to ideal theory in addressing moral dilemmas in the clinic and beyond. In Part II, authors discuss applications of nonideal theory in many areas of bioethics, including reflections on environmental harms, racism and minority health, healthcare injustices during incarceration and detention, and other vulnerabilities experienced by patients from clinical and public health perspectives. The chapters within each section demonstrate the breadth in scope that nonideal theory encompasses, bringing together diverse theorists and approaches into one collection. (shrink)

Two challenges have faced policymakers during the Covid-19 pandemic: First, they must determine the reliability of expert testimony in the face of uncertainty; second, they must determine the relevance of different kinds of expertise with regard to particular decisions. I argue that both these problems can be fruitfully analyzed through the lens of trust by introducing an in-depth case study of Iceland’s handling of the first wave of the Covid-19 pandemic. I contend that the problem of relevance highlights the limited (...) appeal of a thoroughly technocratic society. Value judgments, best realized through democratic processes, are always lurking in the background. (shrink)

Extended mind remains a provocative approach to cognition and mentality. However, both those for and against this approach have tacitly accepted that cognition or mentality can be understood in terms of those sub personal processes ongoing during some task. I label this a process view of cognition (PV). Using Wittgenstein’s philosophical approach, I argue that proponents of extended mind should reject PV and instead endorse a ‘wide view’ of mentality. This wide view clarifies why the hypothesis of extended mind (HEM) (...) is incoherent. However, this view also indicates why the hypothesis of extended cognition (HEC) could be true. (shrink)

ABSTRACT There has been much discussion regarding the acceptable use of sedation for palliation. A particularly contentious practice concerns deep, continuous sedation given to patients who are not imminently dying and given without provision of hydration or nutrition, with the end result that death is hastened. This has been called ‘early terminal sedation’. Early terminal sedation is a practice composed of two legally and ethically accepted treatment options. Under certain conditions, patients have the right to reject hydration and nutrition, even (...) if these are life‐sustaining. Patients are also entitled to sedation as palliation for intolerable, intractable suffering. Though early terminal sedation is thought to be rare at present, the changing nature of palliative medicine suggests its use will increase. Arguments regarding early terminal sedation have failed to recognize early terminal sedation as a distinct legal and ethical entity. It can be seen as both the simple sum of treatment refusal and sedation for palliation, analogous to terminal sedation. It can also be seen as an indivisible palliative treatment, more analogous to assisted suicide or euthanasia. But ultimately, it is wholly analogous neither to terminal sedation given when death is imminent, nor to assisted suicide or euthanasia. This paper contends that early terminal sedation should be considered as a distinct entity. Such a reconception promises to provide a way forward in the debate, practice and policy regarding this contentious area of palliative medicine. (shrink)

It seems uncontroversial that Dalton wrongly believed that atoms are indivisible. However, the correct analysis of Dalton’s belief and the way it relates to contemporary beliefs about atoms is, on closer inspection, far from straightforward. In this paper, I introduce four features that any candidate analysis is plausibly bound to respect. I argue that theories that individuate concepts at the level of understanding are doomed to fail in this endeavor. I formally sketch an alternative and suggest that cases such as (...) the one presented provide support for the claim that the genuine source for concept individuation is public sharable thought.

In an earlier paper the authors discussed some super-tasks by means of a kinematical interpretation. In the present paper we show a semi-formal way that a more abstract treatment is possible. The core idea of our approach is simple: if a super-task can be considered as a union of (finite) tasks, it is natural to define the effect of the super-task as the union of the effects of the finite tasks it consists of. We show that this approach enables us (...) to handle two of the three super-tasks that we discussed earlier. We also argue that recent objections against our original kinematical interpretation do not hold water. One of our arguments is based on the construction of an elegant correspondence between the first of those three super-tasks and Zeno's Achilles and the Tortois. (shrink)

The paper inspects Anderson’s central thesis that Kant’s dogmatic slumber was interrupted by Hume’s critique of metaphysics in his Enquiry concerning Human Understanding, namely, by his critique of the rationalist principle of sufficient reason, which lies at the heart of dogmatic proofs of God’s existence. I recreate the meaning of “Hume’s objection,” define the larger role the principle of sufficient reason plays in Kant’s philosophy, and evaluate the explanatory potential of Anderson’s interpretation in view of Kant’s early and critical texts, (...) as well as his other autobiographical statements. Although Anderson’s hypothesis seems well-founded and even explicates the hidden connection between the entire critical project and the refutation of Spinozism, I argue it is almost impossible to reconcile it with the current research in Kant’s Entwicklungsgeschichte.

In this paper I explore Antony Duff’s claim that there are categorical constraints on the scope of the criminal law that are set by its internal standards. I argue against his view that such constraints are categorical, and I suggest that his account of the nature of the criminal law is partial, and narrows the focus of our enquiry into the scope of the criminal law too much. However, I suggest that the project is an important contribution to our understanding (...) of one central element of the criminal law. (shrink)

Actions are uncontroversially public. However, the prevailing model of explanation in the debate about the de se seems to conflict with this fact by proposing agent-specific explanations that yield agent-specific types of action—i.e. types of action that no two agents can instantiate. Remarkably, this point affects both proponents and critics of the de se. In this paper, I present this kind of problem, characterise the proper level of analysis for action explanation compatible with the publicity of action—i.e. the agent-bound level—and (...) suggest that acknowledgement of this level highlights two important amendments of contemporary views. First, sceptics must accept that, when explanation is attitude-involving, the attitudes mentioned in the explanation of action must refer to the agent. Secondly, and perhaps more surprisingly, proponents of the de se should seek for accounts of de se attitudes that are not confined to a specific agent and are, therefore, sharable across agents.

This article defends the right that Palestinians have to return to the territory governed by Israel. However, it does not defend the duty on Israel to permit return. Whether there is such a duty depends on whether the economic, social and security costs override that right. In order to defend the right of return, it is shown both that the current generation of Palestinians retain a significant interest in return, and that insofar as their interests are diminished, their rights are (...) not diminished proportionally. The interests of Jewish Israelis in excluding the Palestinians are then considered. Their rights of self-determination, it is argued, do not powerfully favour excluding the Palestinians. The economic, social and security costs may do so. Overall, I conclude that either the Israel should grant return to the Palestinians or it should properly acknowledge the right of return and respond appropriately through a powerful effort to compensate and resettle them.

We show that plane hyperbolic geometry, expressed in terms of points and the ternary relation of collinearity alone, cannot be expressed by means of axioms of complexity at most ∀∃∀, but that there is an axiom system, all of whose axioms are ∀∃∀∃ sentences. This remains true for Klingenberg's generalized hyperbolic planes, with arbitrary ordered fields as coordinate fields.

One of three basic types of desire, claims Aristotle, is thumos (‘spirit,’ ‘passion,’ ‘heart,’ ‘anger,’ ‘impulse’). The other two are epithumia (‘appetite’) and boulêsis (‘wish,’ ‘rational desire’). Yet, he never gives us an account of thumos; it has also received relatively little scholarly attention. I argue that thumos has two key features. First, it is able to cognize what I call ‘social value,’ the agent’s own perceived standing relative to others in a certain domain. In human animals, shame and honor (...) are especially important manifestations of social value. Second, thumos provides non-rational motivation to pursue what affirms the agent’s social value and avoid what denies it. Interpretations that hold thumos just is anger, or that its object is the fine (kalon), I argue, are mistaken. My account also explains the role of thumos in moral education. In a virtuous agent thumos will be affectively attuned to the correct social rankings; it will take the practically wise, the lovers of the fine, or moral exemplars, as authorities. (shrink)

The article discusses some of the fundamental conceptual and theoretical aspects of rational choice and moral order. A distinction is drawn between constitutional interests and compliance interests, and it is argued that a viable moral order requires that the two interests somehow be brought into congruence. It is shown that with regard to the prospects for a spontaneous emergence of such congruence, a distinction between two kinds of moral rules which we call trust-rules and solidarity-rules is of crucial importance.

In Sparing Civilians, Seth Lazar claims that in war, with rare exceptions, killing noncombatants is worse than killing combatants. This paper raises some doubts about whether this is an important principle – at least, once we understand Lazar’s clarifications. It also suggests that however it is clarified, it seems false. And it suggests a related principle that more plausible. This related principle applies only to those with just aims, and it applies only to intentional killing rather than to all forms (...) of killing. (shrink)

Problem 2 at the 56th International Mathematical Olympiad asks for all triples of positive integers for which ab−c, bc−a, and ca−b are all powers of 2.
