About MIT Press Ebooks
Today the measurable health burden of neurological and mental health disorders matches or even surpasses any other cluster of health conditions. At the same time, the clinical applications of recent advances in neuroscience are hardly straightforward. In Pragmatic Neuroethics, Eric Racine argues that the emerging field of neuroethics offers a way to integrate such specialties as neurology, psychiatry, and neurosurgery with the humanities and social sciences, neuroscience research, and related healthcare professions, with the goal of tackling key ethical challenges and improving patient care. Racine provides a survey of the often diverging perspectives within neuroethics, offers a theoretical framework supported by empirical data, and discusses the neuroethical implications of such issues as media coverage of neuroscience innovation and the importance of public concerns and lay opinion; nonmedical use of pharmaceuticals for performance enhancement; and the discord between intuitive notions about consciousness and behavior and the scientific understanding of them.
Racine proposes a pragmatic neuroethics that combines pluralistic approaches, bottom-up research perspectives, and a focus on practical issues (in contrast to other more theoretical and single-discipline approaches to the field). [He discusses ethical issues related to powerful neuroscience insights into the mechanisms underlying moral reasoning, cooperative behavior, and such emotional processes as empathy.] In addition, he outlines a pragmatic framework for neuroethics, based on the philosophy of emergentism, which identifies conditions for the meaningful contribution of neuroscience to ethics, and sketches new directions and strategies for meeting future challenges for neuroscience and society.

- Pragmatic Neuroethics is a book based on the reasonable hope that if clinicians and researchers from various disciplines work together in collaboration with different stakeholders, the chances of making a difference for patients suffering from neurological and psychiatric disorders can be increased. It relies on the belief that ethics is a crucial part of this endeavor, and that ethics, the search for the good and for what Aristotle called moral excellence, is inherently part of social and medical acts aiming to alleviate suffering, pain, and daily difficulties for patients. This view is at the heart of this book and of what I describe as “pragmatic neuroethics,” a view of bioethics influenced by various thinkers that emphasizes the pluralistic nature of ethics and society and the value of interdisciplinary collaboration and research to further knowledge and institute beneficial practice changes in healthcare, science, and society.
- The need for an interdisciplinary and collective response to ethical challenges in neuroscience and clinical care—neuroethics—has surfaced in the past years in response to important social, medical, and scientific changes. In many developed countries today, as illustrated by data of the World Health Organization, the combined “health burden” of neurological and mental health disorders matches and even surpasses that of any cluster of health conditions (World Health Organization 2001, 2006). Developing countries are spared neither from this prevalence of neuropsychiatric conditions nor from issues of stigma associated with mental illness and the need for better treatments for neurological disorders. The term “health burden,” often measured in days of lost productivity, may seem overly administrative. Nonetheless, it is a convenient way to illustrate the costs of caregivers without appropriate support and resources; stigma and discrimination; lives that are shattered by illness and isolated suffering; lack of research efforts; and, in some unfortunate cases, suicide. Today, almost everyone can look around and identify, if not themselves, a friend or relative that has faced not only a mental health or neurological problem but the challenges of being respected as a person and finding the internal resources to carry forward. These are the familiar stories of depressed friends or colleagues who never came back to work after falling ill and elderly parents coping with dementia. In proportion to other serious illnesses, diseases of the brain and mind now represent one of the greatest—and still increasing—public health burdens faced by both higher- and lower-income nations.
- This book presents neuroethics as an unprecedented opportunity to integrate healthcare neurospecialties such as neurology, psychiatry, neurosurgery, the humanities, neuroscience research, social science, and allied healthcare professions to tackle the emerging challenges in neuroscience and to improve patient care. There are signs that we are making some headway. Scientists, governments, advocacy groups, and public health authorities are intensely pursuing research to address the causes and consequences of neurological and psychiatric disease and to search for “cures.” The clinical translation of neuroscience is not straightforward, and as neuroscience research progresses and strives to improve clinical practices and public understanding, many scientific unknowns make it difficult to produce practical clinical neuroscience applications. In addition, once some clinical changes are introduced, the pluralistic nature of contemporary societies means that not everyone will always unanimously agree on what is an “advance” or “progress.” For example, if we could know with more accuracy our future risk of developing depression or Alzheimer’s disease—based on a combination of structural brain measures, brain activity patterns, and neurogenetic testing—would everyone feel that it is in their best interest to know? What about the potential of neuropharmacology to generate medicines that can not only treat illnesses but also improve cognitive function in the healthy? And when are scientific advances dealing with complex and sensitive issues or health conditions such as disorders of consciousness ready to be shared with the broader public? Neuroethics signals that promising advances are surfacing but, as they percolate to healthcare and public stakeholders, questions surface about how new insights and new interventions will find their proper place in society to serve individuals and the public good.
- Neuroethics, alongside other initiatives, has surfaced to tackle head on some of the challenges created by advances in neuroscience. However, to date, there have been few theoretical perspectives on this new field and scarce in-depth discussion about its nature and scope. In response, this book provides such a perspective as well as examples of research that attempts to bridge different disciplines to provide frameworks for elucidating and attending to important neuroethics issues. These include, for example, the increasing use of neuropharmacology to enhance performance and the incursion of functional neuroimaging in the world of the humanities and social sciences beyond conventional clinical neuroscience research. I hope that readers will find this book enlightening and stimulating, enough so to encourage reflection, action, or research that will contribute to meeting the broad ethical, scientific, medical, and social challenges that we collectively face.
- Pragmatic Neuroethics pursues a number of goals: (1) to thoroughly review diverging perspectives within neuroethics and provide a constructive critical analysis of the latest literature; (2) to provide a consistent view of the field with compelling arguments that yield a theoretical approach to tackling several problems within neuroethics; (3) to address several key neuroethics issues using empirical research data and a pragmatic approach; and (4) to identify future challenges for neuroscience and society and discuss possible directions for the field of neuroethics. The limitations of this book include the focus on some salient challenges to the detriment of others as well as perspectives that reflect my training in bioethics, social science, and philosophy. For example, legal issues related to neuroscience are not addressed, and I will be the first to admit that many more issues, especially clinically relevant ones, such as stigma, neurodegenerative disease, and aging, pose huge challenges to society. Further, given the range of topics, some will require more attention in the future.
- Pragmatic Neuroethics is divided in two parts. The first section, chapters 1 through 4, reviews recent neuroethics scholarship, provides background on neuroethics, and introduces pragmatism and pragmatic neuroethics. The second section, chapters 5 through 9, presents a series of essays on salient topics in neuroethics such as decision making in disorders of consciousness; public understanding of neuroscience; and policy approaches to “cognitive enhancement.”
- Chapter 1 (“Salient Challenges in Modern Neuroethics”) provides a thematic overview of neuroethics and explains some of the key areas currently under discussion. By gaining acquaintance with these topics, the reader should get a clear sense of why modern neuroethics has surfaced to systematically examine emerging challenges. Chapter 2 (“Reviewing Past and Current Neuroethics: Definitions, Attributes, and Perspectives”) analyzes some early definitions of neuroethics and identifies some distinct views of the field. A review of neuroethics attributes and the ethical, legal, and social issues associated with it in peer review literature, on the Internet, and in print media gives an overall sense of how the field has been characterized in formal academic definitions and beyond. Chapter 3 (“Pragmatic Naturalism in Bioethics”) presents and discusses different waves of naturalism in bioethics, including how neuroethics has reinitiated discussions on the relationship between the biological sciences and the humanities. This chapter argues that bioethics in itself is a form of pragmatic naturalism as illustrated by the field’s commitment to interdisciplinary collaborations and its practical focus. Finally, chapter 4 (“Neuroethics: Exploring the Implications of Pragmatic Naturalism”) explores the implications of pragmatic naturalism by addressing several controversies surrounding neuroethics. It concludes by highlighting some of the characteristics of pragmatic neuroethics, such as the integration of pluralism, bottom-up research approaches, and a focus on practical issues that distinguish this approach from other, more theoretical or more monodisciplinary views of the field.
- The second part of this book presents a series of essays that are nourished by both the background material and the theoretical framework of pragmatic neuroethics laid out in chapters 1 through 4. Chapter 5 (“Public Understanding of Neuroscience Innovation and Emerging Interpretations of Neuroscience Research”) highlights the importance of public understanding from a pragmatic perspective in order to take into consideration not only expert opinions about ethics in neuroscience but also public concerns and emerging lay interpretations of neuroscience research. This chapter discusses various forms of media coverage of neuroscience innovation. Chapter 6 (“Enhancement of Performance with Neuropharmaceuticals: Pragmatism and the Culture Wars”) stems from a context of increasing prevalence and salience of nonmedical uses of neuropharmaceuticals for performance enhancement. This chapter examines critically some of the assumptions behind the conservative and liberal moral-political approaches to this issue and makes the case from a pragmatic standpoint for the recognition of pluralism and for approaches that minimize harm, promote autonomy, and urge considerations for the public good. Chapter 7 (“Disorders of Consciousness in an Evolving Neuroscience Context”) provides background information and some discussion of different clinical conditions such as the vegetative state and the minimally conscious state, called collectively disorders of consciousness, in an evolving neuroscience context that challenges some assumptions about these disorders. Chapter 8 (“Communication of Prognosis in Disorders of Consciousness and Severe Brain Injury”) builds on the material presented in chapter 7 to discuss in more detail why there are lingering sources of confusion in disorders of consciousness. Specifically, I argue that there is a strong tension at work between, on the one hand, intuitive notions about consciousness and behavior and, on the other hand, scientific understanding and medical language describing consciousness and behavior. Chapter 9 (“Social Neuroscience: A Pragmatic Epistemological and Ethical Framework for the Neuroscience of Ethics”) builds on the naturalism inherent to pragmatic naturalism and discusses the possibility that neuroscience provides powerful insights into the mechanisms underlying moral reasoning, cooperative behavior, and emotional processes such as empathy. This chapter briefly introduces social neuroscience and the neuroscience of ethics and highlights some potential benefits and misunderstandings created by this area of research. It then presents a pragmatic framework based on the philosophy of emergentism. This framework yields conditions and guideposts for the meaningful contribution of neuroscience to ethics. This emergentist and pragmatic framework also debunks common arguments against the introduction of neuroscience research into ethics as well as overstated promises. The conclusion of
- Pragmatic Neuroethics (“Neuroethics and Future Challenges for Neuroscience, Ethics, and Society”) revisits some major issues discussed in this book and sketches recommendations and strategies for moving ahead.
- I hope that readers of this book will enjoy these neuroethics contributions. It is also my hope, even though I realize much still needs to be done, that each chapter will stimulate reflection, action, and ideas for research that embrace pragmatic goals while remaining open to genuine dialogue in the search for collaborative and practical solutions.
- Although it bears the signature of one man, this book, which captures some of my basic opinions, would have been absolutely impossible without the support of many colleagues and students. This is an opportunity for me to acknowledge the help and support of colleagues, family, and friends who have directly or indirectly inspired and supported my work in the last years.
- I would like to sincerely thank Nicole Palmour for reviewing this manuscript on several occasions and providing constructive and helpful comments. I want to thank former and current trainees and assistants of the Neuroethics Research Unit: Amaryllis Ferrand, Cynthia Forlini, Constance Deslauriers, Emily Bell, Ghislaine Mathieu, Bruce Maxwell, William Affleck, Zoë Costa-von Aesch, Marie-Josée Dion, Marta Karczewska, Matthew Seidler, David Bouvier, David Risse, Catherine Rodrigue, Lila Karpowicz, and Danaë Larivière-Bastien. Their work and presence have inspired me along the way and are truly appreciated. My work reflects part of the ongoing daily conversations and exchanges I have had with them, and I am immensely indebted to them.
- I consider myself privileged to have received the mentorship of outstanding individuals along the years. I have been fortunate to cross paths with senior scholars who possess extraordinary energy, creativity, and commitment. I would like to thank in particular Judy Illes, Hubert Doucet, and Bartha Knoppers for their generous time, ongoing support, and encouragements. Nothing can replace the mentorship and advice a young scholar receives from senior colleagues or the intellectual exchanges that occur within collegial and respectful environments. I would like to thank particularly Walter Glannon for his helpful guidance throughout this project, James Bernat for helpful comments on this manuscript, and an additional anonymous reviewer.
- The idea for writing this book originates partly from the days of my postdoctoral fellowship at the Stanford Center for Biomedical Ethics (SCBE). I would like to thank accordingly the leadership of the SCBE, in particular David Magnus, Henry Greely, and Mildred Cho, for support and the staff members (Anne Footer, Paula Bailey, Joyce Prasad, and Shobha Kumar) who helped me in many different ways to make this a successful journey. I want to thank the students who worked with me on various projects at the SCBE, including Sarah Waldman, Adri Van der Loos, Ofek Bar-Ilan, Stacey Kallem, Neil Mukhopadhyay, Allyson Mackey, Vivian Chau, Rakesh Amaram, Marisa Gallo, and Tessa Watt. I am indebted for their assistance in numerous research projects, and the exchanges I have had with them are marked in my past and present and will remain with me for the future.
- Pragmatic Neuroethics materialized during a visiting fellowship at the Brocher Foundation in August 2007, where I had the privilege to put on paper the project for this book. The beautiful and inspiring settings provided by the foundation’s location on the shores of Lake Geneva and the friendly exchanges with colleagues helped me prepare the proposal and nourished this project as it unfolded. I would like to thank the leadership of the Brocher Foundation, in particular Cécile Caldwell Vulliéty, and the friendly staff, especially Raji Sultan for his kind assistance. I would also like to acknowledge the support of colleagues I met during my enjoyable stay there (Anthony Mark Cutter, Thomas Douglas, Bert Gordijn, Rouven Porz, Michael Selgelid); they made this a remarkable and inspiring experience for me and my family members (Nathalie, André-Anne, Gabrielle, and Amélie). The foundation’s generous support for the publication of this book deserves special recognition.
- During the writing of this work and the work that preceded it, I received fellowships, awards, and grants from several agencies, including the Social Sciences and Humanities Research Council, the Fonds de la recherche en santé du Québec, the National Institutes of Health (grant awarded to Judy Illes), the Greenwall Foundation (grant awarded to Judy Illes), the Canadian Institutes of Health Research (Ethics Office; Institute of Neurosciences, Mental Health and Addiction; Institute of Human Development, Child and Youth Health), the CIHR-funded States of Mind Network (Françoise Baylis), and the CIHR-funded Pediatric Neuroimaging Ethics Network (Jocelyn Downie). The support from these agencies and from various peer communities has made much of the work underlying this book possible.
- I am grateful for the support from the unique Institut de recherches cliniques de Montréal (IRCM), especially Louis-Gilles Durand, who has been an invaluable source of inspiration and advice in the past three years. Jeannine Amyot’s impressive administrative skills and commitment to supporting the Neuroethics Research Unit need to be underscored and acknowledged. I thank all my IRCM colleagues who have provided feedback on material presented in this book and who believe in the legacy of Jacques Genest, the founder of the institute, who was committed early in the 1970s to creating the first Canadian Bioethics Center. The example and vision he has set to bridge research, healthcare, and ethics in the service of humankind will be with us for decades and hopefully centuries. Thanks to Claudia Jones and Nicole Campeau at the library, and to the IRCM leadership, in particular its director, Tarik Möröy, for his confidence in and ongoing support of this project and others.
