In the debate on the ethics of the non-medical use of pharmaceuticals for cognitive performance enhancement in healthy individuals there is a clear division between those who view “cognitive enhancement” as ethically unproblematic and those who see such practices as fraught with ethical problems. Yet another, more subtle issue, relates to the relevance and quality of the contribution of scholarly bioethics to this debate. More specifically, how have various forms of speculation, anticipatory ethics, and methods to predict scientific trends and (...) societal responses augmented or diminished this contribution? In this paper, we use the discussion of the ethics of cognitive enhancement to explore the positive and negative contribution of speculation in bioethics scholarship. First, we review and discuss how speculation has relied on different sets of assumptions regarding the non-medical use of stimulants, namely: terminology and framing; scientific aspects such as efficacy and safety; estimates of prevalence and consequent normalization; and the need for normative reflection and regulatory guidelines. Second, three methodological guideposts are proposed to alleviate some of the pitfalls of speculation: acknowledge assumptions more explicitly and identify the value attributed to assumptions; validate assumptions with interdisciplinary literature; and adopt a broad perspective to promote more comprehensive reflection. We conclude that, through the examination of the controversy about cognitive enhancement, we can employ these methodological guideposts to enhance the value of contributions from bioethics and minimize potential epistemic and practical pitfalls in this case and perhaps in other areas of bioethical debate.

ABSTRACT There is a growing interest in various forms of naturalism in bioethics, but there is a clear need for further clarification. In an effort to address this situation, I present three epistemological stances: anti‐naturalism, strong naturalism, and moderate pragmatic naturalism. I argue that the dominant paradigm within philosophical ethics has been a form of anti‐naturalism mainly supported by a strong ‘is’ and ‘ought’ distinction. This fundamental epistemological commitment has contributed to the estrangement of academic philosophical ethics from major social (...) problems and explains partially why, in the early 1980s, ‘medicine saved the life of ethics’. Rejection of anti‐naturalism, however, is often associated with strong forms of naturalism that commit the naturalistic fallacy and threaten to reduce the normative dimensions of ethics to biological imperatives. This move is rightly dismissed as a pitfall since ethics is, in part, a struggle against the course of nature. Rejection of naturalism has drawbacks, however, such as detering bioethicists from acknowledging the implicit naturalistic epistemological commitments of bioethics. I argue that a moderate pragmatic form of naturalism represents an epistemological position that best embraces the tension of anti‐naturalism and strong naturalism: bioethics is neither disconnected from empirical knowledge nor subjugated to it. The discussion is based upon historical writings in philosophy and bioethics. (shrink)

Common understandings of neuroethics, i.e., of its distinctive nature, are premised on two distinct sets of claims: (1) neuroscience can change views about the nature of ethics itself and neuroethics is dedicated to reaping such an understanding of ethics; (2) neuroscience poses challenges distinct from other areas of medicine and science and neuroethics tackles those issues. Critiques have rightfully challenged both claims, stressing how the first may lead to problematic forms of reductionism while the second relies on debatable assumptions about (...) the nature of bioethics specialization and development. Informed by philosophical pragmatism and our experience in neuroethics, we argue that these claims are ill-founded and should give way to pragmatist reconstructions. Namely, neuroscience, much like other areas of empirical research on morality, can provide useful information about the nature of morally problematic situations but it does not need to promise radical and sweeping changes to ethics based on neuroscientism. Furthermore, the rationale for the development of neuroethics as a specialized field need not to be premised on the distinctive nature of the issues it tackles or of neurotechnologies. Rather, it can espouse an understanding of neuroethics as both a scholarly and a practical endeavor dedicated to resolving a series of problematic situations raised by neurological and psychiatric conditions.

Assessment of outcome following deep brain stimulation (DBS) has traditionally focused on symptom-specific and quality-of-life measures. Greater attention needs to be paid to the diversity of patient goals and values, as well as recognition of the shifting nature of those goals over the course of DBS therapy. We report preliminary data from an empirical study examining patients’ goals with respect to DBS in the treatment of Parkinson disease. We argue that a multifaceted assessment of outcome over time, including well-validated symptom (...) measures, quality of life, and functional and patient specific metrics, is ethically necessary in order to fulfill fiduciary and professional responsibilities. These assessments should be augmented with a deliberative multidisciplinary process of review and evaluation. Such an approach will lead to improved inform consent, promote better clinical research, and facilitate good patient care by providing a systematic mechanism for capturing and acting on important patient insights. These processes become increasingly critical as DBS begins to be applied to neuropsychiatric disorders. (shrink)

The phenomenological effects of deep brain stimulation (DBS) on the self of the patient remains poorly understood and under described in the literature, despite growing evidence that a significant number of patients experience postoperative neuropsychiatric changes. To address this lack of phenomenological evidence, we conducted in-depth, semistructured interviews with 17 patients with Parkinson's disease who had undergone DBS. Exploring the subjective character specific to patients' experience of being implanted gives empirical and conceptual understanding of the potential phenomenon of DBS-induced self-estrangement. (...) Our study concluded that (1) the more patients preoperatively felt alienated by their illness, the more they experienced postoperative self-estrangement, and (2) the notion of self-estrangement seems to exist in association with certain common qualitative characters, namely, loss of control, which reflects a deteriorative estrangement, and distorted perception of capacities, which reveals a restorative estrangement. These findings indicate that subjective self-reports help us to understand some aspects of the potential phenomenon of DBS-induced self-estrangement. (shrink)

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

While neuroethics is generally thought to be a modern addition to the broader field of bioethics, this subdiscipline has existed in clinical practice throughout the course of the 20th century. In this essay, Fins describes an older tradition of clinical neuroethics that featured such physician-humanists as Sir William Osler, Wilder Penfield, and Fred Plum, whose work and legacy exploring disorders of consciousness is highlighted. Their normative work was clinically grounded and focused on the needs of patients, in contrast to modern (...) neuroethics, which is more speculative and distant from the lived reality of the clinic. Using recent developments in the diagnosis and treatment of disorders of consciousness, and the history of the vegetative and minimally conscious states, Fins asks why modern neuroethics has taken this turn and what can be done to restore clinical neuroethics to a more proportionate place in the field.

In Human Nature and Conduct, first published in 1922, Dewey brings the rigor of natural sciences to the quest for a better moral system.

Once a neural implant has shown some efficacy during initial research trials, it begins to enter the world of clinical application. This culminates when the implant becomes approved for a particular indication. However, the ethical challenges continue as the technology is adopted as a standard of practice. Patient eligibility criteria, as documented by inclusion and exclusion criteria with any new treatment, are not always clearly quantified and defined. These vagaries can result in considerable debate regarding who should or should not (...) proceed with surgery. There is often considerable room for clinical judgment that can result in extension of the treatment to a wider range of patients. The ethical questions that arise in clinical decisionmaking differ significantly from those inherent in engineering design and research development. (shrink)

The notion that our society, its education system and its intellectual life, is characterised by a split between two cultures – the arts or humanities on one hand and the sciences on the other – has a long history. But it was C. P. Snow's Rede lecture of 1959 that brought it to prominence and began a public debate that is still raging in the media today. This fiftieth anniversary printing of The Two Cultures and its successor piece, A Second (...) Look features an introduction by Stefan Collini, charting the history and context of the debate, its implications and its afterlife. The importance of science and technology in policy run largely by non-scientists, the future for education and research, and the problem of fragmentation threatening hopes for a common culture are just some of the subjects discussed.
