The value of extending the human lifespan remains a key philosophical debate in bioethics. In building a case against the extension of the species-typical human life, Nicolas Agar considers the prospect of transforming human beings near the end of their lives into Galapagos tortoises, which would then live on decades longer. A central question at stake in this transformation is the persistence of human consciousness as a condition of the value of the transformation. Agar entertains the idea that consciousness could (...) persist in some measure, but he thinks little is to be gained from the transformation because the experiences available to tortoises pale in comparison to those available to human beings. Moreover, he thinks persisting human consciousness and values would degrade over time, being remade by tortoise needs and environment. The value available in the transformation would not, then, make the additional years of life desirable. Agar’s account does not, however, dispose of the tortoise transformation as a defensible preference. Some people might still want this kind of transformation for symbolic reasons, but it would probably be better that no continuing human consciousness persist, since that consciousness would be inexpressible as such. Even so, it is not irrational to prefer various kinds of lifespan extension even if they involve significant modifications to human consciousness and values. (shrink)

A number of philosophers working in applied ethics and bioethics are now earnestly debating the ethics of what they term “moral bioenhancement.” I argue that the society-wide program of biological manipulations required to achieve the purported goals of moral bioenhancement would necessarily implicate the state in a controversial moral perfectionism. Moreover, the prospect of being able to reliably identify some people as, by biological constitution, significantly and consistently more moral than others would seem to pose a profound challenge to egalitarian (...) social and political ideals. Even if moral bioenhancement should ultimately prove to be impossible, there is a chance that a bogus science of bioenhancement would lead to arbitrary inequalities in access to political power or facilitate the unjust rule of authoritarians; in the meantime, the debate about the ethics of moral bioenhancement risks reinvigorating dangerous ideas about the extent of natural inequality in the possession of the moral faculties.

In his 1993 article ‘The Coming Technological Singularity: How to survive in the posthuman era’ the computer scientist Virnor Vinge speculated that developments in artificial intelligence might reach a point where improvements in machine intelligence result in smart AI’s producing ever-smarter AI’s. According to Vinge the ‘singularity’, as he called this threshold of recursive self-improvement, would be a ‘transcendental event’ transforming life on Earth in ways that unaugmented humans are not equipped to envisage. In this paper I argue Vinge’s idea (...) of a technologically led intelligence explosion is philosophically important because it requires us to consider the prospect of a posthuman condition succeeding the human one. What is the ‘humanity’ to which the posthuman is ‘post’? Does the possibility of a posthumanity presuppose that there is a ‘human essence’, or is there some other way of conceiving the human-posthuman difference? I argue that the difference should be conceived as a historically emergent disconnection between individuals, not in terms of the presence or lack of essential properties. I also suggest that these individuals should not be conceived in narrow biological terms but in ‘wide’ terms permitting biological, cultural and technological relations of descent between human and posthuman. Finally, I consider the ethical implications of this metaphysics of the posthuman. If, as I claim, the posthuman difference is not one between kinds but between individuals, we cannot specify its nature a priori but only a posteriori. Thus the only way to evaluate the posthuman condition would be to witness the emergence of posthumans. The implications of this are somewhat paradoxical. We are not currently in a position to evaluate the posthuman condition. Since there are no posthumans, the condition of posthumanity is not defined. However, posthumans could result from some iteration of our current technical activity, so we have an interest in understanding what they might be like. It follows that we have an interest in making or becoming posthumans. (shrink)

In Humanity’s End: Why We Should Reject Radical Enhancement, Nicholas Agar presents a novel argument against the prospect of radical life-extension. Agar’s argument hinges on the claim that extended lifespans will result in people’s lives being dominated by the fear of death. Here we examine this claim and the surrounding issues in Agar’s discussion. We argue, firstly, that Agar’s view rests on empirically dubious assumptions about human rationality and attitudes to risk, and secondly, that even if those assumptions are granted, (...) the fears that Agar adverts to are unlikely to dominate people’s lives if and when radical life-extension is made possible. Further, we claim that the structure of the decision-making process around life-extension is unlikely to be the way that it would have to be in order for Agar’s claims about fear of death to make sense. Finally, we argue that Agar is implicitly committed to a narrow conception of human value. In response, we suggest that the pursuit of life-extension can itself be seen as an expression of certain important aspects of our distinctively human nature. (shrink)

Heidegger’s thoughts on modern technology have received much attention in many disciplines and fields, but, with a few exceptions, the influence has been sparse in biomedical ethics. The reason for this might be that Heidegger’s position has been misinterpreted as being generally hostile towards modern science and technology, and the fact that Heidegger himself never subjected medical technologies to scrutiny but was concerned rather with industrial technology and information technology. In this paper, Heidegger’s philosophy of modern technology is introduced and (...) then brought to bear on medical technology. Its main relevance for biomedical ethics is found to be that the field needs to focus upon epistemological and ontological questions in the philosophy of medicine related to the structure and goal of medical practice. Heidegger’s philosophy can help us to see how the scientific attitude in medicine must always be balanced by and integrated into a phenomenological way of understanding the life-world concerns of patients. The difference between the scientific and the phenomenological method in medicine is articulated by Heidegger as two different ways of studying the human body: as biological organism and as lived body. Medicine needs to acknowledge the priority of the lived body in addressing health as a way of being-in-the-world and not as the absence of disease only. A critical development of Heidegger’s position can provide us with a criterion for distinguishing the uses of medical technologies that are compatible with such an endeavor from the technological projects that are not.

The prospect of human genetic enhancement requires an institutional response, and probably the creation of new institutions. The governance of genetic enhancement technologies, moreover, needs to be global in scope. In this article, I analyze the debate on the global governance of human genetic enhancement. I begin by offering a philosophical justification for the need to adopt a global framework for governance of technologies that would facilitate the improvement of non-pathological genetic traits. I then summarize the main concrete proposals that (...) have recently emerged to govern genome editing at the global level. Finally, I develop some impediments that limit the impetus for global governance of genetic enhancement. (shrink)

From a behaviorist perspective, the desire to upload “minds” is already being realized on a mass, hyper-industrial scale thanks to the convergence of cognitive computing and Big Data. The accusation is that the “mind” is not an entity that exists intracranially. Instead, it is conceived as a process of individuation, which occurs in different modes and numbers. Some narratives of mind-uploading and technics in popular culture are explored: Transcendence (2014, dir. Wally Pfister) and Player Piano by Kurt Vonnegut. The discussed (...) issues consider Bernard Stiegler’s phenomenological notion of originary default and Thierry Bardini’s analysis of junk. Several questions are raised regarding miscalculations, accidents, in addition to Nicolas Agar’s discussion on the end of humanity, and Daniel Dennett’s Multiple Drafts theory within the context of exteriorization, which is considered as constitutive of interiority.

A 10,000+ word critical overview of analytic philosophy devoted to life's meaning, with some focus on books and more recent works.

Since a number of years, popular and scientific interest in resilience is rapidly increasing. More recently, also neuroscientific research in resilience and the associated neurobiological findings is gaining more attention. Some of these neuroscientific findings might open up new measures to foster personal resilience, ranging from magnetic stimulation to pharmaceutical interventions and awareness-based techniques. Therefore, bioethics should also take a closer look at resilience and resilience research, which are today philosophically under-theorized. In this paper, we analyze different conceptualizations of resilience (...) and argue that especially one-sided understandings of resilience which dismiss social and cultural contexts of personal resilience do pose social and ethical problems. On a social level such unbalanced views on resilience could hide and thereby stabilize structural social injustices, and on an individual level it might even lead to an aggravation of stress-related mental health problems by overexerting the individual. Furthermore, some forms of fostering resilience could be a latent form of human enhancement and trigger similar criticisms. (shrink)

I discuss three tiers of technological innovation: mild innovation, or the acceleration by technology of a human activity aimed at a good; moderate innovation, or the obviation by technology of an activity aimed at a good; and radical innovation, or the altering by technology of the human condition so as to change what counts as a good. I argue that it is impossible to morally assess proposed innovations within any of these three tiers unless we rehabilitate a natural-law ethical framework. (...) And I offer some moral starting points within such a framework, in connection with innovations of each of the three types. (shrink)

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)

The prospect of cognitive enhancement well beyond current human capacities raises worries that the fundamental equality in moral status of human beings could be undermined. Cognitive enhancement might create beings with moral status higher than persons. Yet, there is an expressibility problem of spelling out what the higher threshold in cognitive capacity would be like. Nicholas Agar has put forward the bold claim that we can show by means of inductive reasoning that indefinite cognitive enhancement will probably mark a difference (...) in moral status. The hope is that induction can determine the plausibility of post‐personhood existence in the absence of an account of what the higher status would be like. In this article, we argue that Agar's argument fails and, more generally, that inductive reasoning has little bearing on assessing the likelihood of post‐personhood in the absence of an account of higher status. We conclude that induction cannot bypass the expressibility problem about post‐persons. (shrink)

Neuroethics applies cognitive neuroscience for prescribing alterations to conceptions of self and society, and for prescriptively judging the ethical applications of neurotechnologies. Plentiful normative premises are available to ground such prescriptivity, however prescriptive neuroethics may remain fragmented by social conventions, cultural ideologies, and ethical theories. Herein we offer that an objectively principled neuroethics for international relevance requires a new meta-ethics: understanding how morality works, and how humans manage and improve morality, as objectively based on the brain and social sciences. This (...) new meta-ethics will simultaneously equip neuroethics for evaluating and revising older cultural ideologies and ethical theories, and direct neuroethics towards scientifically valid views of encultured humans intelligently managing moralities. Bypassing absolutism, cultural essentialisms, and unrealistic ethical philosophies, neuroethics arrives at a small set of principles about proper human flourishing that are more culturally inclusive and cosmopolitan in spirit. This cosmopolitanism in turn suggests augmentations to traditional medical ethics in the form of four principled guidelines for international consideration: empowerment, non-obsolescence, self-creativity, and citizenship.

Any serious ethical discussion of the enhancement of human nature must begin with a reasonably accurate picture of the causal-historical structure of the living world. In this Comment, I show that even biologically sophisticated ethical discussions of the biomedical enhancement of species and speciel natures are susceptible to the kind of essentialistic thinking that Lewens cautions against. Furthermore, I argue that the same evolutionary and developmental considerations that compel Lewens to reject more plausible conceptions of human nature pose equally serious (...) problems for some prominent critiques of biomedical enhancement that presuppose the existence of a “given” biological potential that can be distorted by agentic cultural influences.

Recent discussions of cognitive enhancement often note that drugs and technologies that improve cognitive performance may do so at the risk of “cheapening” our resulting cognitive achievements Arguing about bioethics, Routledge, London, 2012; Harris in Bioethics 25:102–111, 2011). While there are several possible responses to this worry, we will highlight what we take to be one of the most promising—one which draws on a recent strand of thinking in social and virtue epistemology to construct an integrationist defence of cognitive enhancement.. (...) According to such a line, there is—despite initial appearances to the contrary—no genuine tension between using enhancements to attain our goals and achieving these goals in a valuable way provided the relevant enhancement is appropriately integrated into the agent’s cognitive architecture. In this paper, however, we show that the kind of integration recommended by such views will likely come at a high cost. More specifically, we highlight a dilemma for users of pharmacological cognitive enhancement: they can meet the conditions for cognitive integration at the significant risk of dangerous dependency, or remain free of such dependency while foregoing integration and the valuable achievements that such integration enables. After motivating and clarifying the import of this dilemma, we offer recommendations for how future cognitive enhancement research may offer potential routes for navigating past it. (shrink)

In this article, part of a special issue on meaning in life and medical ethics, I argue that several issues encountered in a bioethical context are not adequately addressed only with values such as morality and welfare. I maintain, more specifically, that the value of what makes a life meaningful is essential to being able to provide conclusive judgements about which decisions to make. After briefly indicating how meaningfulness differs from rightness and happiness, I point out how it is plausibly (...) central to making decisions in six ‘life and death’ matters. My aim is not to draw any firm conclusions about what to do when it comes to these topics, but rather to show that in order to arrive at any, one cannot plausibly ignore the category of life’s meaning that has, until recently, been nearly absent from Western bioethics since its inception.

This paper offers new arguments to reject the alleged dream of immortality. In order to do this, I firstly introduce an amendment to Michael Hauskeller’s approach of the “immortalist fallacy”. I argue that the conclusion “we do not want to live forever” does not follow from the premise “we do not want to die”. Next, I propose the philosophical turn from “normally” to “under these circumstances” to resolve this logical error. Then, I review strong philosophical critiques of this transhumanist purpose (...) of immortality in the literature. There are two key questions related to the possibility of fulfilling this goal: the hard problem of consciousness and the personal identity dilemma. Finally, I defend a specific type of indefinite life and justify that it is more desirable than our current limited life. (shrink)

On the basis of two thought experiments, I argue that self-building technologies are possible given our current level of technological progress. We could already use technology to make us instantiate selfhood in a more perfect, complete manner. I then examine possible extensions of this thesis, regarding more radical self-building technologies which might become available in a distant future. I also discuss objections and reservations one might have about this view.

Transhumanism is a scientific and philosophical movement that proposes to overcome, through new technologies, the restrictions imposed on us by our biological condition. Some transhumanists assume that the struggle against natural limits could lead to a radical change in our body or even to its replacement. Other authors, such as Nicholas Agar, propose a moderate enhancement that does not exceed the framework of what we understand to be human. In this article, I will offer a plausible interpretation of the project (...) of human enhancement from a Thomistic perspective. To carry out my analysis, I will focus on three fundamental metaphysical and anthropological questions: How do advocates of radical enhancement understand the relationship between limits, imperfections and evils in human nature? How is this relationship understood from moderate positions? And Is any of these proposals compatible with Aquinas’ anthropology? I will conclude that the identification of limits with imperfections and evils assumed by radical positions is incompatible with Aquinas’ anthropology. Nevertheless, this does not entail that any bio-modification is unacceptable. Aquinas’ peculiar metaphysics, together with its anthropology in which the natural, the supernatural and the preternatural realms intertwine, can offer an interesting framework to assess the human enhancement project.

In a paper in this journal, Neil Levy challenges Nicholas Agar’s argument for the irrationality of mind-uploading. Mind-uploading is a futuristic process that involves scanning brains and recording relevant information which is then transferred into a computer. Its advocates suppose that mind-uploading transfers both human minds and identities from biological brains into computers. According to Agar’s original argument, mind-uploading is prudentially irrational. Success relies on the soundness of the program of Strong AI—the view that it may someday be possible to (...) build a computer that is capable of thought. Strong AI may in fact be false, an eventuality with dire consequences for mind-uploading. Levy argues that Agar’s argument relies on mistakes about the probability of failed mind-uploading and underestimates what is to be gained from successfully mind-uploading. This paper clarifies Agar’s original claims about the likelihood of mind-uploading failure and offers further defense of a pessimistic evaluation of success. (shrink)

This chapter addresses a general question: What is responsible risking? It explores the notion of "responsible risking" as a thick moral concept, and it argues that the notion can be given moral content that could be action-guiding and add an important tool to our moral toolbox. To impose risks responsibly, on this view, is to take on responsibility in a good way. A core part of responsible risking, this chapter argues, is some version of a Forethought Condition. Such a condition (...) requires us to not make decisions or plans such that we could not deliver on our responsibility obligations. This chapter argues that three moral obligations can be derived from descriptive notions of responsibility. They are (1) the control condition, (2) the responsibility to fix condition, and (3) the responsibility to explain condition. The idea is that in order to impose risks responsibly we ought not act in ways that undermine our ability to remain in control over the risks, undermine our ability to sort out negative outcomes by reparations or compensation, or undermine our prospects of providing an explanation for our actions that also makes sense in hindsight and to those affected. This idea is then tried out on the case of germline gene editing. It is argued that such a moral notion of responsibility is also action-guiding when we do not know for certain what is the morally right or obligatory action all-things-considered due to epistemic gaps.

According to the Norwegian philosopher Peter Wessel Zapffe, human life is filled with so much suffering that procreation is morally impermissible. In the first part of this paper I present Zapffe’s pessimism-based argument for anti-natalism, and contrast it with the arguments for anti-natalism proposed by Arthur Schopenhauer and David Benatar. In the second part I explore what Zapffe’s pessimism can teach us about biomedical enhancement. I make the case that pessimism counts in favor of pursuing biomedical enhancements. The reason is (...) that the worse we take the baseline human condition to be, the stronger are our reasons to try to alter humanity, and the weaker are our reasons to fear technology-driven extinction. The prospect of enhancement, I further argue, gives pessimists a reason to reject anti-natalism. (shrink)

The historical sensibility of Western modernity is best captured by the phrase “acting upon a story that we can believe.” Whereas the most famous stories of historians facilitated nation-building processes, philosophers of history told the largest possible story to act upon: history itself. When the rise of an overwhelming postwar skepticism about the modern idea of history discredited the entire enterprise, the historical sensibility of “acting upon a story that we can believe” fell apart to its constituents: action, story form, (...) and belief in a feasible future outcome. Its constituent parts are nevertheless still hold, either separately or in paired arrangements. First, believable stories are still told, but without an equally believable future outcome to facilitate. Second, in the shape of what I call the prospect of unprecedented change, there still is a feasible vision of a future (in prospects of technology and the Anthropocene), but it defies story form. And third, it is even possible to upon that feasible future, but such action aims at avoiding worst case scenarios instead of facilitating best outcomes. These are, I believe, features of an emerging postwar historical sensibility that the theory and philosophy of history is yet to understand. (shrink)

Utilitarians must think collectively about the future because many contemporary moral issues require collective responses to avoid possible future harms. But current rule utilitarianism does not accommodate the distant future. Drawing on my recent books Future People and Ethics for a Broken World, I defend a new utilitarianism whose central ethical question is: What moral code should we teach the next generation? This new theory honours utilitarianism’s past and provides the flexibility to adapt to the full range of credible futures (...) – from futures broken by climate change to the digital, virtual and predictable futures produced by various possible technologies.

Nicholas Agar argues that we should avoid certain ‘radical’ enhancement technologies. One reason for this is that they will alienate us from current sources of value by altering our evaluative outlooks. We should avoid this, even if enhancing will provide us with novel, objectively better sources of value. After noting the parallel between Agar’s views and G. A. Cohen’s work on the ‘conservative bias’, I explore Agar’s suggestion in relation to two kinds of radical enhancement: cognitive and anti-ageing. With regard (...) to both, there are reasons to doubt Agar’s empirical predictions about the severity of the evaluative changes we will undergo. Nonetheless, there is some force to the argument as applied to cognitive enhancement; in particular, radical cognitive enhancement may endanger our current valuable relationships with our loved ones. However, even if we find this a plausible worry for radical cognitive enhancement, it is not plausible for even radical anti-ageing enhancement, because the change Agar predicts will not affect our core motivations in the way that cognitive enhancement threatens to.

Currently, some philosophers and technicians propose to change the fundamental constitution of Homo sapiens, as by significantly altering the genome, implanting microchips in the brain, and pursuing related techniques. Among these proposals are aspirations to guide humanity’s evolution into new species. Some philosophers have countered that such species alteration is unethical and have proposed international policies to protect species integrity; yet, it remains unclear on what basis such right to species integrity would rest. An answer may come from an unexpected (...) angle of rights issues: Some cultures have indicated that they want no part of our technological culture, preferring to retain their practices. Yet, rights documents do not explicitly establish that any individual has a right to species integrity. Careful interpretation of rights documents nonetheless reveals that such a right to species integrity is implicit. Interpreting these so as to reveal this needed right is also necessary to retain the foundations of rights documents and institutions. Further, acknowledging a right of species integrity could mean, because of practicalities, a limit to the freedom of proponents to implement proposals to manipulate the species. (shrink)

Nicholas Agar has recently argued that it would be irrational for future human beings to choose to radically enhance themselves by uploading their minds onto computers. Utilizing Searle’s argument that machines cannot think, he claims that uploading might entail death. He grants that Searle’s argument is controversial, but he claims, so long as there is a non-zero probability that uploading entails death, uploading is irrational. I argue that Agar’s argument, like Pascal’s wager on which it is modelled, fails, because the (...) principle that we (or future agents) ought to avoid actions that might entail death is not action guiding. Too many actions fall under its scope for the principle to be plausible. I also argue that the probability that uploading entails death is likely to be lower than Agar recognizes. (shrink)

The covid-19 pandemic has revealed a partially forgotten vulnerability. This very hostile period has made us more aware of the finitude of our life as well as the dangers to which we are exposed as the biological organisms that we are. Faced with such a panorama, transhumanism has taken advantage of this situation to claim, more forcefully than ever, the benefits that the application of technologies on human beings could have. Yet, at the same time, opponents of this movement have (...) pointed out, with equal intensity, how the pandemic has wakened many of its promises. We show how both the former and the latter continue to hold radically different positions regarding how to address vulnerability. However, both have seen the pandemic as an opportunity to highlight what should be the right direction for the future of our species. This event, which is not rooted in the field of science-fiction, could be decisive in rethinking the great challenges that await us. (shrink)

The paper discusses criticisms against pharmacological cognitive enhancement from a liberal perspective. The criticisms point to the consequences of cognitive enhancement in third parties and in the agents, as well as in independent values. According to the article, these criticisms are not convincing. On the contrary, it argues that under certain assumptions there are good reasons in favor of free access to cognitive enhancement.

The prospect of radical human enhancement challenges us with how we can even think about the choice to enhance or not enhance. Whether as individuals or as citizens of liberal democracies, we already recognize the prospect of a future that is defined by technology, without being able to predict or imagine what it will be like or how we should try to influence it. We can also be sure that radical enhancement of ourselves as individuals, or of a large proportion (...) of our fellow citizens, will alter the very standards and values by which we, as individuals or polities, later evaluate decisions to enhance – this is one version of the more general problem of transformative choice. In response to these challenges, it is plausible that we have no alternative to choosing and acting on our current desires and values, rather than our expected future values or some set of values that is objectively authoritative for us. On the other hand, our current value-outlooks include a degree of openness to our desires and values themselves changing, and for this reason we can often finesse the problem of transformative choice when it arises in everyday situations. On the gripping hand, this does not entirely solve the problem when it comes to something as dramatic and unprecedented as radical enhancement. There is some reason for an incremental, rather than apocalyptic, approach, even if we are sympathetic to a human future shaped by radical enhancement initiatives. (shrink)

How should ethics help decide the morality of enhancing morality? The idea of morally enhancing the human brain quickly emerged when the promise of cognitive enhancement in general began to seem realizable. However, on reflection, achieving moral enhancement must be limited by the practical challenges to any sort of cognitive modification, along with obstacles particular to morality’s bases in social cognition. The objectivity offered by the brain sciences cannot ensure the technological achievement of moral bioenhancement for humanity-wide application. Additionally, any (...) limited moral enhancement will not easily fulfil ethical expectations. Three hypothetical scenarios involving putative moral enhancement help illustrate why. Philosophical concerns about the “Does-Must Dichotomy” and the “Factor-Cause Plurality,” as I label them, forbid easy leaps from views about morality on to conclusions about ways to enhance morality, and then further on to ethically justifying those enhancements. A modest and realistic approach to moral enhancement emerges from exploring these issues. (shrink)

The ethics of human enhancement has been a hotly debated topic in the last 15 years. In this debate, some advocate examining science fiction stories to elucidate the ethical issues regarding the current phenomenon of human enhancement. Stories from science fiction seem well suited to analyze biomedical advances, providing some possible case studies. Of particular interest is the work of screenwriter Andrew Niccol (Gattaca, S1m0ne, In Time, and Good Kill), which often focuses on ethical questions raised by the use of (...) new technologies. Examining the movie In Time (2011), the aim of this paper is to show how science fiction can contribute to the ethical debate of human enhancement. In Time provides an interesting case study to explore what could be some of the consequences of radical life-extension technologies. In this paper, we will show how arguments regarding radical life-extension portrayed in this particular movie differ from what is found in the scientific literature. We will see how In Time gives flesh to arguments defending or rejecting radical life-extension. It articulates feelings of unease, alienation and boredom associated with this possibility. Finally, this article will conclude that science fiction movies in general, and In Time in particular, are a valuable resource for a broad and comprehensive debate about our coming future. (shrink)

Over the coming century, the accelerating advance of bioenhancement technologies, robotics, and artificial intelligence (AI) may significantly broaden the qualitative range of sentient and intelligent beings. This article proposes a taxonomy of such beings, ranging from modified animals to bioenhanced humans to advanced forms of robots and AI. It divides these diverse beings into three moral and legal categories—animals, persons, and presumed persons—describing the moral attributes and legal rights of each category. In so doing, the article sets forth a framework (...) for extending the concept of personhood well beyond its current boundaries, assigning moral standing to a variety of biological and nonbiological beings. The author concludes that six of the eight subgroups of such beings deserve to be treated as persons or as if they were persons, with full consideration for their presumed interests, rights, obligations, and capabilities for ethically significant agency and patiency.
