The enhancement debate in neuroscience and biomedical ethics tends to focus on the augmentation of certain capacities or functions: memory, learning, attention, and the like. Typically, the point of contention is whether these augmentative enhancements should be considered permissible for individuals with no particular “medical” disadvantage along any of the dimensions of interest. Less frequently addressed in the literature, however, is the fact that sometimes the _diminishment_ of a capacity or function, under the right set of circumstances, could plausibly contribute (...) to an individual's overall well-being: more is not always better, and sometimes less is more. Such cases may be especially likely, we suggest, when trade-offs in our modern environment have shifted since the environment of evolutionary adaptation. In this article, we introduce the notion of “diminishment as enhancement” and go on to defend a _welfarist_ conception of enhancement. We show how this conception resolves a number of definitional ambiguities in the enhancement literature, and we suggest that it can provide a useful framework for thinking about the use of emerging neurotechnologies to promote human flourishing.

“Love hurts”—as the saying goes—and a certain amount of pain and difficulty in intimate relationships is unavoidable. Sometimes it may even be beneficial, since adversity can lead to personal growth, self-discovery, and a range of other components of a life well-lived. But other times, love can be downright dangerous. It may bind a spouse to her domestic abuser, draw an unscrupulous adult toward sexual involvement with a child, put someone under the insidious spell of a cult leader, and even inspire (...) jealousy-fueled homicide. How might these perilous devotions be diminished? The ancients thought that treatments such as phlebotomy, exercise, or bloodletting could “cure” an individual of love. But modern neuroscience and emerging developments in psychopharmacology open up a range of possible interventions that might actually work. These developments raise profound moral questions about the potential uses—and misuses—of such anti-love biotechnology. In this article, we describe a number of prospective love-diminishing interventions, and offer a preliminary ethical framework for dealing with them responsibly should they arise. (shrink)

Memory modification technology (MMT) refers to the use of neurotechnologies to intervene in memories. Many scholars have reflected on the ethical issues in MMT, but a comprehensive review of this topic has not been seen. This article presents the first scoping review study of ethical issues in MMT using a bibliometric and systematic approach. After thorough examination, 133 records of key literature are included in this scoping review. Six core ethical themes are extracted: (1) self, identity, and authenticity; (2) autonomy (...) and informed consent; (3) welfare and happiness; (4) safety and risks; (5) responsibility and obligation; (6) social and legal justice. More detailed analyses are conducted on the moral stances and reasons held by different scholars concerning these ethical themes. As can be seen, current debates exhibit certain shortcomings, including ambiguous ethical concepts and a restricted scope of analysis. Therefore, we call for deeper reflections on the philosophical foundations, more precise definitions of ethical terms, and more comprehensive examinations of neurotechnological applications, in order to better address the ethical challenges in the future.

For nearly two decades, ethicists have expressed concerns that the further development and use of memory modification technologies (MMTs)—techniques allowing to intentionally and selectively alter memories—may threaten the very foundations of who we are, our personal identity, and thus pose a threat to our well-being, or even undermine our “humaneness.” This paper examines the potential ramifications of memory-modifying interventions such as changing the valence of targeted memories and selective deactivation of a particular memory as these interventions appear to be at (...) the same time potentially both most promising clinically as well as menacing to identity. However, unlike previous works discussing the potential consequences of MMTs, this article analyzes them in the context of the narrative relational approach to personal identity and potential issues related to autonomy. I argue that such a perspective brings to light the ethical aspects and moral issues arising from the use of MMTs that have been hidden from previously adopted approaches. In particular, this perspective demonstrates how important the social context in which an individual lives is for the ethical evaluation of a given memory-modifying intervention. I conclude by suggesting that undertaking memory modifications without taking into account the social dimension of a person’s life creates the risk that she will not be able to meet one of the basic human needs—the autonomous construction and maintenance of personal identity. Based on this conclusion, I offer some reflections on the permissibility and advisability of MMTs and what these considerations suggest for the future. (shrink)

The potential of memory modification techniques (MMTs) has raised concerns and sparked a debate in neuroethics, particularly in the context of identity and authenticity. This paper addresses the question whether and how MMTs influence authenticity. I proceed by drawing two distinctions within the received views on authenticity. From this, I conclude that an analysis of MMTs based on a dual-basis, process view of authenticity is warranted, which implies that the influence of MMTs on authenticity crucially depends on the specifics of (...) how memory modification would eventually work. Therefore, I continue with a systematic analysis of possible properties of MMTs in which I distinguish between the dimensions of memories and the kinds of experiences that can be modified as well as the properties of the process of memory modification. The impact of MMTs on authenticity is analyzed regarding the possible properties of MMTs and based on a narrative approach to authenticity which fulfills the requirements of a dual-basis, process view of authenticity. Lastly, I explore the potential of MMTs to shift the balance between self-discovery and self-creation within authenticity and thereby alter the concept itself as well as the value of authenticity.

In her short story “Stable Strategies for Middle Management,” Eileen Gunn imagines a future in which Margaret, an office worker, seeks radical genetic enhancements intended to help her secure the middle-management job she wants. One source of the story’s tension and dark humor is dramatic irony: readers can see that the enhancements Margaret buys stand little chance of making her life go better for her; enhancing is, for Margaret, probably a prudential mistake. This paper argues that our positions in the (...) real world are sufficiently similar to Margaret’s position in Gunn’s fictional world that we should take this story seriously as grounding an argument from analogy for the conclusion that radical genetic enhancements are, for us, probably a prudential mistake. The paper then defends this method. When the question at hand is one of speculative ethics, there is no method better fit to the purpose than argument from analogy to speculative fiction. (shrink)

Funding: Research funded by Canadian Institutes of Health Research, NNF 80045, States of Mind: Emerging Issues in Neuroethics. While there are those who object to the prospective use of propranolol to prevent or treat post-traumatic stress disorder (PTSD), most obstreperous among them the President’s Council on Bioethics, the use of propranolol can be justified for patients with severe PTSD. Propranolol, if effective, will alter the quality of certain memories in the brain. But this is not a serious threat to the (...) self understood in terms of narrative identity. A narrative identity framework acknowledges that memory is always being subtly altered or modified. For severe cases of PTSD propranolol may help victims who don’t respond to any other therapy or therapy combination regain their authentic self-narrative and engage once more in life activities. For those whose symptoms are not so severe the potential risks and side-effects of the drug may outweigh the benefits. Patients and family members should be allowed to decide, in consultation with their physician, whether this drug is appropriate in their case. (shrink)

At least since 2003, when the US President’s Council on Bioethics published Beyond Therapy: Biotechnology and the Pursuit of Happiness , there has been heated debate about the ethics of using pharmacology to reduce the intensity of emotions associated with painful memories. That debate has sometimes been conducted in language that obfuscates as much as it illuminates. I argue that the two sides of the debate actually agree that, in general, it is good to reduce the emotional intensity of memories (...) associated with traumatic events, when (as in the case of Post Traumatic Stress Disorder) the intensity of those memories is dis proportionate to the precipitating traumatic event. Both sides also agree that, in general—not as an ironclad rule—it is bad to reduce the emotional intensity of memories associated with difficult but normal human problems of living, when the intensity of the emotions is proportionate to those problems. Between those two areas of agreement, there is a zone of ambiguity, in which reasonable people, who proceed from different but equally ethical frameworks, may indeed reach different conclusions about the same set of facts. But I will argue that even in the zone of ambiguity, there is more agreement than the language favored by the different frameworks sometimes suggests. Ultimately, I suggest that if we see the extent to which the substantive differences between the two frameworks are smaller than their articulators’ language sometimes suggests, we can engage in a more productive conversation about whether a particular intervention will facilitate or diminish human flourishing.

The neural basis of human memory is incredibly complex. We argue that the diversity of neural systems underlying various forms of memory suggests that any discussion of enhancing ‘memory’ per se is too broad, thus obfuscating the biopolitical debate about human enhancement. Memory can be differentiated into at least four major systems with largely dissociable neural substrates. We outline each system, and discuss both the practical and the ethical implications of these diverse neural substrates. In practice, distinct neural bases imply (...) the possibility, and likely the necessity, of specific approaches for the safe and effective enhancement of various memory systems. In the debate over the ethical and social implications of enhancement technologies, this fine-grained perspective clarifies—and may partially mitigate—certain common concerns in enhancement debates, including issues related to safety, fairness, coercion, and authenticity. While many researchers certainly appreciate the neurobiological complexity of memory, the political debate tends to revolve around a monolithic one-size-fits-all conception. The overall project—exploring how human enhancement technologies affect society – stands to benefit from a deeper appreciation of memory’s neurobiological diversity. (shrink)

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.

Neuroethics, in its modern form, investigates the impact of brain science in four basic dimensions: the self, social policy, practice and discourse. In this study, we analyzed a set of 461 peer-reviewed articles with neuroethics content, published by authors from 32 countries. We analyzed the data for: (1) trends in the development of international neuroethics over time, and (2) how challenges at the intersection of ethics and neuroscience are viewed in countries that are considered developed by International Monetary Fund (IMF) (...) standards, and in those that are developing. Our results demonstrate a steady increase in global participation in neuroethics from 1989 to 2005, characterized by an increase in numbers of articles published specifically on neuroethics, journals publishing these articles, and countries contributing to the literature. The focus from all countries was on the practice of brain science and the amelioration of neurological disease. Indicators of technology creation and diffusion in developing countries were specifically correlated with increases in publications concerning policy implications of brain science. Neuroethics is an international endeavor and, as such, should be sensitive to the impact that context has on acceptance and use of technological innovation. (shrink)

Die Posttraumatische Belastungsstörung (PTBS) ist ein schwerwiegendes psychisches Krankheitsbild, das Betroffene nach dem Erleben traumatisierender Situationen entwickeln. Im Zusammenhang mit den Auslandseinsätzen der Bundeswehr ist die PTBS bei Soldaten in den letzten Jahren verstärkt in den Fokus der deutschen Öffentlichkeit gerückt. Auch zivile Traumata bergen ein großes PTBS-Risiko. Seit einigen Jahren werden Methoden zur medikamentösen Prävention der PTBS erforscht. Die beiden wichtigsten Ansätze, die Prävention mit zentralnervös wirkenden Betablockern und Glukokortikoiden, basieren auf der Idee, durch den Eingriff in neuroendokrine Stressachsen (...) Einfluss auf die Art und Weise zu nehmen, in der die Erinnerung im Gedächtnis konsolidiert wird. Durch eine Entemotionalisierung und Abschwächung entsprechender Gedächtnisspuren soll das spätere Auftreten einer PTBS verhindert werden. Beide Ansätze zeigen in Pilotstudien vielversprechende Ergebnisse. Angesichts der herausragenden Bedeutung des Gedächtnisses für Individuum und Gesellschaft sollten Ansätze zur medikamentösen Gedächtnismodifikation (MGM) unter neuroethischen Gesichtspunkten diskutiert und bewertet werden. Der Text beleuchtet die MGM zur PTBS-Prävention entlang von fünf Problemachsen: 1) der Einflussnahme von MGM auf den Prozess der normalen psychischen Verarbeitung traumatischer Erlebnisse, 2) der Gefahr einer Entkopplung von Erinnerung und Realität, 3) der Bedeutung von emotionaler Erinnerung für die Moral, 4) der sozialen, juristischen und historischen Relevanz einer wahrhaftigen Erinnerungskultur und 5) der potenziellen Förderung eines gesellschaftlichen Medikalisierungsprozesses. Trotz ernsthaft zu diskutierender ethischer Bedenken ist – vor dem Hintergrund der Schwere des Krankheitsbilds – aus unserer Sicht eine MGM zur PTBS-Prävention grundsätzlich begrüßenswert, sollte jedoch derzeit nur im Rahmen klinischer Studien erfolgen. Hierfür stellen wir acht forschungsethische Aspekte zur Diskussion, die bei solchen Studien zu berücksichtigen sind. (shrink)

This study deals specifically with one of the most relevant issues in neuro-ethics, namely the philosophical classification of so-called memory dampening, which refers to the attenuation of traumatic memories with the help of medication. Numerous neuroethical questions emerge from this issue. For example, how is a person’s identity affected by using such drugs? Does one still remain the same person? Would propranolol, for example, as a memory-dampening agent lead to a fundamental change in one’s identity? Are not a person’s negative (...) memories also part of their identity and present personality? These questions are examined from the perspective of the seventeenth-century Islamic philosopher, Mullā Ṣadrā. The goal is to shed light on the neuroethical foundations of memory dampening and personal identity from an Islamic philosophical perspective. (shrink)

The recent emergence of reprogramming technologies to convert brain cell types or epigenetically alter neurons and neural progenitors in vivo and in situ hold significant promises in brain repair and neuronal aging reversal. However, given the significant epigenetic and transcriptomic changes to components of the existing neuronal cells and network, we question if these reprogramming technology might inadvertently alter or erase memory engrams, conceivably resulting in changes in narrative identity or personality. We suggest that the nature of these alterations might (...) be less predictable compared to memory and personality changes known to be associated with diseases, drugs or brain stimulation therapies. While research in applying reprogramming technologies to neurological ailments and aging should continue, more targeted analyses should be put in place in animal experiments to gauge the severity and degree of memory alterations, and appropriate risk and benefit analyses should be conducted before these technologies move into human trials.

The paper deals with a perspective of Christian philosophy on artificial memory erasuse for psychotherapeutic purposes. Its central question is whether a safe and reliable technology of memory erasure, once it is available, would be acceptable from a Christian ethics point of view. The main facet of this question is related to the Christian ethics requirement of contrition for the past wrongs, which in the case of memory erasure of particulary troubling experiences and personal choices would not be possible. The (...) paper argues that there are limits to the ethical significance of contrition in the writings of the leading Christian fathers on the theme, where excessive suffering and inability to forgive oneself for one’s actions is an impediment to the achivement of tranquility of mind and spiritual redemption, rather than a prerequisite for it. The paper thus concludes that there is no hindrance in principle from the Christian ethics point of view to pursuing a voluntary and selective memory erasure as a psychotherapeutic technique once a fully adequate technology is available.

Just over 20 years ago, molecular biologists Leonie Ringrose and Renato Paro published an article with a provocative title, “Remembering Silence”, in BioEssays. The article focused on how epigenetic elements could return to their silent state, operationally defined as their epigenetic status before their modulation by experimental or environmental factors. Though Ringrose and Paro's article was on fruit flies and factors affecting embryological growth, the article asked a question of considerable importance to rapidly expanding research in neuroepigenetics on the correlation (...) between trauma and neuropsychiatric risk: If you experience a traumatic event and, as a result, acquire an epigenetic trait that is considered pathological, can you free yourself of that trait? Ultimately, we are interested in how a return to silence is envisioned in neuroepigenetics research, how interventions purported to bring about that silence might function, and what this might mean for people who live in the aftermath of trauma.

Using medical advances to enhance human athletic, aesthetic, and cognitive performance, rather than to treat disease, has been controversial. Little is known about physicians? experiences, views, and attitudes in this regard. We surveyed a national sample of physicians to determine how often they prescribe enhancements, their views on using medicine for enhancement, and whether they would be willing to prescribe a series of potential interventions that might be considered enhancements. We find that many physicians occasionally prescribe enhancements, but doctors hold (...) nuanced and ambiguous views of these issues. Most express concerns about the potential effects of enhancements on social equity, yet many also believe specific enhancements that are safe and effective should be available but not covered by insurance. These apparently contradictory views might reflect inherent tensions between the values of equity and liberty, which could make crafting coherent social policies on medical enhancements challenging.
