One recurring criticism of the best interests standard concerns its vagueness, and thus the inadequate guidance it offers to care providers. The lack of an agreed definition of ‘best interests’, together with the fact that several suggested considerations adopted in legislation or professional guidelines for doctors do not obviously apply across different groups of persons, result in decisions being made in murky waters. In response, bioethicists have attempted to specify the best interests standard, to reduce the indeterminacy surrounding medical decisions. (...) In this paper, we discuss the bioethicists’ response in relation to the state's possible role in clarifying the best interests standard. We identify and characterise two clarificatory strategies employed by bioethicists —elaborative and enumerative—and argue that the state should adopt the latter. Beyond the practical difficulties of the former strategy, a state adoption of it would inevitably be prejudicial in a pluralistic society. Given the gravity of best interests decisions, and the delicate task of respecting citizens with different understandings of best interests, only the enumerative strategy is viable. We argue that this does not commit the state to silence in providing guidance to and supporting healthcare providers, nor does it facilitate the abuse of the vulnerable. Finally, we address two methodological worries about adopting this approach at the state level. The adoption of the enumerative strategy is not defeatist in attitude, nor does it eventually collapse into (a form of) the elaborative strategy. (shrink)

It is evident, in the face of the COVID-19 pandemic that has physicians confronting death and dying at unprecedented levels along with growing data suggesting that physicians who care for dying patients face complex emotional, psychological and behavioural effects, that there is a need for their better understanding and the implementation of supportive measures. Taking into account data positing that effects of caring for dying patients may impact a physician’s concept of personhood, or “what makes you, ‘you’”, we adopt Radha (...) Krishna’s Ring Theory of Personhood (RToP) to scrutinise the experiences of physicians working in intensive care units (ICU) using a fictional scenario that was inspired by real events. The impact of death and dying, its catalysts, internal constituents, external factors, dyssynchrony, and buffers, specific to ICU physicians, were identified and explored. Such a framework allows for ramifications to be considered holistically and facilitates the curation of strategies for conflict resolution. This evaluation of the RToP acknowledges the experience and wide-ranging effects it has on ICU physicians. As such, our findings provide insight into their specific needs and highlight the importance of support on a personal and organisational level. Although further research needs to be conducted, the RToP could serve as the basis for a longitudinal assessment tool supported by the use of portfolios or mentorship due to their provision of personalised, appropriate, specific, timely, accessible and long-term support.

Background Supporting physicians in Intensive Care Units s as they face dying patients at unprecedented levels due to the COVID-19 pandemic is critical. Amidst a dearth of such data and guided by evidence that nurses in ICUs experience personal, professional and existential issues in similar conditions, a systematic scoping review is proposed to evaluate prevailing accounts of physicians facing dying patients in ICUs through the lens of Personhood. Such data would enhance understanding and guide the provision of better support for (...) ICU physicians. Methods An SSR adopts the Systematic Evidenced Based Approach to map prevailing accounts of caring for dying patients in ICUs. To enhance the transparency and reproducibility of this process, concurrent and independent use of tabulated summaries, thematic analysis and directed content analysis is adopted. Results Eight thousand three hundred fifty-eight abstracts were reviewed from four databases, 474 full-text articles were evaluated, 58 articles were included, and the Split Approach revealed six categories/themes centered around the Innate, Individual, Relational and Societal Rings of Personhood, conflicts in providing end of life care and coping mechanisms employed. Conclusion This SSR suggests that caring for dying patients in ICU impacts how physicians view their personhood. To resolve conflicts within individual concepts of personhood, physicians use prioritization, reframing and rely on accessible, personalized support from colleagues to steer coping strategies. An adapted form of the Ring Theory of Personhood is proposed to direct timely personalized, appropriate and holistic support. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Clinical CommentaryChong Siow Ann, Associate ProfessorDr. G appears to experiencing symptoms of schizophrenia, which is arguably the most severe mental disorder and which afflicts about one in a hundred people. This is a psychotic disorder that causes disturbances and distortions in thinking, including neurocognitive impairments, perception and behaviour. There is no cure for this often devastating disorder. Current antipsychotic medications can alleviate some of the symptoms but it often (...) comes at a price as these antipsychotics have burdensome side effects.A feature of this disorder is anosognosia, which is a lack of awareness or “insight” that an illness is present. This lack of insight presents a particular challenge because these individuals would, as in the case of Dr. G, refuse needed treatment as they do not perceive that they are ill. This is not necessarily an all-or-none phenomenon but is rather more complex and multidimensional; there might be an unawareness or recognition on behalf of the patient that they are suffering from a mental illness, the failure to appreciate the necessity of treatment; and/or the inability to recognise and define the psychotic symptoms like unusual thoughts and hallucinations as signs of illness1 and in many instances, all three are present. It is also by no means uncommon. Studies have found that between 60% and 80% of people with schizophrenia lack awareness of their illness to varying degrees.2This phenomenon remains an enigma. Some regard it as a form of psychological defence against the harsh reality of a psychotic illness — awareness of having a chronic and devastating illness might lead to demoralisation, hopelessness and suicide.3 Recent research, however, [End Page 250] indicates that this psychological denial plays a small part, if any, and instead has found an association with certain neuropsychological and neurocognitive deficits,4 as well as functional and structural brain abnormalities in the frontal lobe of the brain.5The prevailing clinical view thus is that this is an intrinsic and organic aspect of the schizophrenic illness which has nothing to do with wilfulness but rather the incapacity to perceive the presence of the illness. Edwin Fuller Torrey, an eminent psychiatrist and executive director of the Stanley Medical Research Foundation, calls anosognosia the “single largest reason why individuals with schizophrenia and bipolar disorder do not take their medications”, and he has remarked that “to keep talking about civil liberty is illogical. Patients are anything but free when they’re at the beck and call of their own delusions”.6It is also this view that it is a product of a brain disorder that some — particularly patients — find unacceptable. At one level, it does not take into context the person’s own experiences, and at a deeper level it calls into question the conception of the self with its capacity to exercise judgements and the autonomy to make decisions.This is a perennial ethical issue in psychiatry when people with severe mental illnesses refuse treatment. This becomes a Catch-22 situation where part of the illness that needs treatment is also preventing any treatment to be given: implicit in the principle of informed consent for treatment is that the person should be aware of the nature and course of their illness and acknowledge the need for treatment. While there are laws for involuntary commitment, the bar is usually high in that there must be a clear and present risk of harm to the person or others. Alan Stone, a professor of law and psychiatry at Harvard University proposed a possible justification for involuntary treatment based on his “thank-you theory” which assumes that patients will become well and subsequently agree that the intervention was in their best interests but research suggests that only half of these patients would admit so.7One suggested mechanism is the use of advance directives — psychiatry’s version of the living will in which people can specify what sort of medical care they would like should they become mentally unwell and unable to exercise appropriate judgement. An intrinsic part of this might include a “Ulysses contract” — just as Ulysess instructed his crew to lash him to the mast of the his ship so that he could... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Underplayed Ethics and the Dilemmas of Psychiatric CareChong Siow Ann and Tamra LysaghtThe practice of psychiatry is fraught with uncertainty. The exact causes and the biological substrates underlying mental disorders remain to be elucidated; even the diagnosis of these disorders is descriptive and not based on an etiological understanding and no biological diagnostic markers have been validated. The manifestation of almost all mental disorders results from a complex interaction (...) of biological and environmental factors which encompasses the patient’s unique life history, experiences and relationship with others and the community. In the face of such uncertainties — at times extending to the types of treatment (psychiatry is generally acknowledged not be an exact science) — it has been argued that adopting a pragmatic approach is necessary.1 Accordingly, this approach necessitates high ethical standards among mental health practitioners.Some mental illnesses are associated with varying degrees and types of cognitive impairments. Others have certain symptoms like auditory hallucinations and delusions that might severely compromise the patients’ autonomy, distort their sense of reality, increase the risk of harm to themselves or others and render them incapable of making informed decisions in their treatment and participation in research.Consequently, there are issues that are particular to the provision of mental healthcare. These include the need for enforced involuntary treatment with the corollary of depriving a patient of his personal liberty even [End Page 173] though it is often justified on the grounds that it is in the patient’s best interests. However, at times, it is the legal and societal obligation of mental health practitioners to protect those who might be harmed from the patient’s action that might seem to be more pressing. In this situation of double agency, lies the tension of providing confidential care for patients and acting as “an agent of the state” where that patient’s confidentiality might be breached and his liberty infringed upon. This situation is further aggravated by the stigma that clings ever so tenaciously to those who suffer from mental disorders and where it is the norm to stereotype them as dangerous and unpredictable.Consideration of a patient’s autonomy is also challenged by characteristics that are unique to the practice of psychiatry. The prescription of certain psychotropic medications can alter how people think and feel, while psychotherapy works towards changing the patient’s views and values. The philosopher, Jennifer Radden, describes this process as “re-forming the patient’s whole self or character … akin to the responsibilities of raising children”.2 The psychotherapeutic relationship is thus particularly personal and intimate because patients are asked to provide information that often reveals their innermost feelings, fears and fantasies. This information is provided on the basis of trust and assurance of confidentiality, and with expectation of being helped.Jeremy Holmes and Gwen Adshead have elaborated on the vulnerability of patients seeking psychotherapy: they might be particularly susceptible to exploitation because their past experiences of being exploited have led to their distress and help seeking — their dependency and the extreme privacy of the therapeutic relationship make any transgression difficult to be uncovered.3 There is a calamitous combination of the “unconscious wish in the patient to be used” with the complicity of an unethical therapist seeking to fulfil his own interests.4As in any other doctor-patient relationship, the relationship between the mental healthcare practitioner and the patient is one of unequal power where the former is ascendant. While that power should be exercised to heal and to relieve suffering, it also gives the practitioner tremendous power “to harm, reject, misunderstand, or exploit patients who struggle with the experience of mental illness, which itself may generate helplessness, despair, distress, and exceptional dependence on the clinician”.5 Given the potential of doing good and harm coupled with the likelihood of being so significant in the life of the patient,6 providing care for those with mental disorders and distress is necessarily ethically exacting — arguably more so than in other medical practice settings. [End Page 174]This precariousness has led to the suggestion that ethics in psychiatry should have a special status and that the more general principles of biomedical ethics are too limited in scope to...

This paper intends to append the frame of dialectic upon St. John of the Cross’ delineation of mysticism. Its underlying hypothesis is that the dialectical structuring of St. John’s mystical theology promises to unravel the web of relational concepts embedded within his immense writings on this unique phenomenon. It is hoped that as a consequence of this undertaking, relevant pairs of correlative opposites that figure prominently in mysticism can be elucidated and perhaps come to some form of resolution.

A common assumption in the selection of nonhuman animal subjects for research and the approval of research is that, if the risks of a procedure are too great for humans, and if there is a so-called scientific necessity, then it is permissible to use nonhuman animal subjects. I reject the common assumption as neglecting the central ethical issue of the permissibility of using nonhuman animal subjects and as being inconsistent with the principle of justice used in human subjects research ethics. (...) This principle requires that certain classes of individuals not be subjected to a disproportionate share of the burdens or risks of research. I argue for an extension of this principle to nonhuman animal research and show that a prima facie violation of the principle occurs because nonhuman animals bear an overwhelmingly disproportionate share of the risks of research without sufficient justification or reciprocal benefit.

What should we do about “tainted” public commemorations? Recent events have highlighted the urgency of reaching a consensus on this question. However, existing discussions appear to be dominated by two naïve opposing views – to remove or preserve them. My aims in this essay are two-fold. First, I argue that the two views are not naïve, but undergirded by concerns with securing self-respect and with the character of our engagement with the past. Second, I offer a qualified defence of vandalising (...) tainted commemorations. The defence comprises two parts. I consider two prominent suggestions – to install counter-commemorations and to add contextualising plaques – and argue that they are typically beset with difficulties. I then argue that in some circumstances, constrained vandalism is a response to tainted commemorations which effectively adjudicates the demands of the two opposing views. (shrink)

The term, "objectionable commemorations”, refers to a broad category of public artefacts – such as, and especially, memorials, monuments and statues – that are regarded as morally problematic in virtue of what or whom they honour. In this regard, they are a special class of public artefacts that are subject to public contestation. In this paper, we survey the general ethical and political issues on this topic. First, we categorise the arguments on offer in the literature, concerning the objectionable nature (...) of such commemorations. Second, we review common political responses to objectionable commemorations. Finally, we identify fruitful areas for further philosophical inquiry on this topic. (shrink)

Humanitarian assistance in conflicts sometimes undermines local coping strategies, reinforces wartime economies, and strengthens the existing power structures. This article argues that some victims of conflicts are made extremely vulnerable and uniquely dependent on humanitarian agencies. In this case, humanitarian agencies have a distinct obligation to assist them. This article considers one novel account that justifies the continued provision of aid to victims of conflicts and rejects the widespread view that aid should be withdrawn to avoid its negative impact. This (...) article presents the “Distinct Dependence Argument” to address the aid dependency predicament in conflicts. It explores the degree of vulnerability and dependence of victims of conflicts and evaluates humanitarian agencies’ causal responsibility in causing such vulnerability and dependency. (shrink)

We live in the Age of Big Data. In medicine, artificial intelligence and machine learning algorithms, fueled by big data, promise to change how physicians make diagnoses, determine prognoses, and develop new treatments. An exponential rise in articles on these topics is seen in the medical literature. Recent applications range from the use of deep learning neural networks to diagnose diabetic retinopathy and skin cancer from image databases, to the use of various machine learning algorithms for prognostication in cancer and (...) cardiovascular disease. Many factors are driving the adoption of AI in health care, from... (shrink)
