Developments in medical science have afforded us the opportunity to improve and enhance the human species in ways unthinkable to previous generations. Whether it's making changes to mitochondrial DNA in a human egg, being prescribed Prozac, or having a facelift, our desire to live longer, feel better and look good has presented philosophers, medical practitioners and policy-makers with considerable ethical challenges. But what exactly constitutes human improvement? What do we mean when we talk of making "better" humans? In this book (...) Michael Hauskeller explores these questions and the ideas of human good that underpin them. Posing some challenging questions about the nature of human enhancement, he interrogates the logic behind its processes and examines the justifications behind its criteria. Questioning common assumptions about what constitutes human improvement, Hauskeller asks whether the criteria proposed by its advocates are convincing. The book draws on recent research as well as popular representations of human enhancement from advertising to the internet, and provides a non-technical and accessible survey of the issues for readers and students interested in the ethics and politics of human enhancement.

:It has been argued that moral bioenhancement is desirable even if it would make it impossible for us to do what is morally required. Others find this apparent loss of freedom deplorable. However, it is difficult to see how a world in which there is no moral evil can plausibly be regarded as worse than a world in which people are not only free to do evil, but also where they actually do it, which would commit us to the seemingly (...) paradoxical view that, under certain circumstances, the bad can be better than the good. Notwithstanding, this view is defended here. (shrink)

Michael Sandel's opposition to the project of human enhancement is based on an argument that centres on the notion of giftedness. Sandel claims that by trying to ?make better people? we fall prey to, and encourage, an attitude of mastery and thus lose, or diminish, our appreciation of the giftedness of life. Sandel's position and the underlying argument have been much criticised. In this paper I will try to make sense of Sandel's reasoning and give an account of giftedness that (...) defends its relevance for the ethical assessment of the human enhancement project. In order to do so, I will also look at virtue-related notions, such as gratitude and humility, and distinguish the gifted from the merely given. The failure to acknowledge this distinction gives rise to one of the most common objections to Sandel's argument. Other objections will be shown to rest on similar misunderstandings. (shrink)

Nicholas Agar argues that it is possible, and even likely, that radically enhanced human beings will turn out to be ‘post-persons’, that is, beings with a moral status higher than that of mere persons such as us.1 This would mean that they will be morally justified in sacrificing our lives and well-being not merely in cases of emergency, but also in cases of ‘supreme opportunities’ , that is, whenever such a sacrifice leads to ‘significant benefits for post-persons’. For this reason, (...) Agar believes, it would be morally wrong to allow any cognitive enhancement of people that might entail the risk of moral status enhancement.However, neither are there sufficient grounds to expect radically enhanced human beings to have a higher moral status than unenhanced human beings, nor would it, even if they did, be morally wrong to bring about their existence. We use moral status ascriptions mostly as a convenient shorthand to indicate a difference in capacities that strikes us as morally relevant. Rocks have zero moral status because they cannot feel or think, so we cannot hurt or kill them. Whatever we do to them, it does not affect them. Animals, on the other hand, …. (shrink)

Famously, Bernard Williams has argued that although death is an evil if it occurs when we still have something to live for, we have no good reason to desire that our lives be radically extended because any such life would at some point reach a stage when we become indifferent to the world and ourselves. This is supposed to be so bad for us that it would be better if we died before that happens. Most critics have rejected Williams’ arguments (...) on the grounds that it is far from certain that we will run out of things to live for, and I don't contest these objections. Instead, I am trying to show that they do not affect the persuasiveness of Williams’ argument, which in my reading does not rely on the claim that we will inevitably run out of things to live for, but on the far less contentious claim that it is not unthinkable we will do so and the largely ignored claim that if that happens, we will have died too late.

This essay is a reflection on our lived experience of being human, or of some prominent aspects of being human, in light of rising demands to use already existing and soon to be developed technologies to fundamentally change what we are. The aspects the essay focuses on are, first, our existential vulnerability and, second, our desire to live a life that, in some way or another, matters and is in that sense meaningful.

Disgust is often believed to have no special moral relevance. However, there are situations where disgust and similar feelings like revulsion, repugnance, or abhorrence function as the expression of a very strong moral disapproval that cannot fully be captured by argument. I call this kind of disgust moral disgust.Although it is always in principle possible to justify our moral disgust by explaining what it is in a given situation or action that disgusts us, the feeling of disgust often comes first (...) and either draws our attention to the fact that there is something wrong in the first place, or makes us aware that the kind of wrongness we are dealing with surpasses what can be accounted for by established moral theory. In both cases moral disgust serves an important purpose for an adequate moral evaluation of diverse situations and the actions from which they result. (shrink)

-/- Sorgner (2009, 29) has argued that Bostrom (2005, 4) was wrong to maintain that there are only surface-level similarities between Nietzsche’s vision of the overman, or overhuman, and the transhumanist conception of the posthuman. Rather, he claims, the similarities are “significant” and can be found “on a fundamental level”. However, I think that Bostrom was in fact quite right to dismiss Nietzsche as a major inspiration for transhumanism. There may be some common ground, but there are also essential differences, (...) some of which I am going to point out in this brief reply. (shrink)

Genetic engineering is often looked upon with disfavour on the grounds that it involves "tampering with nature". Most philosophers do not take this notion seriously. However, some do. Those who do tend to understand nature in an Aristotelian sense, as the essence or form which is the final end or telos for the sake of which individual organisms live, and which also explains why they are as they are. But is this really a tenable idea? In order to secure its (...) usage in present day ethics, I will first analyze the contexts in which it is applied today, then discuss the notion of telos as it was employed by Aristotle himself, and finally debate its merits and defend it, as far as possible, against common objections.

I argue that Mill introduced the distinction between quality and quantity of pleasures in order to fend off the then common charge that utilitarianism is ‘a philosophy for swine’ and to accommodate the (still) widespread intuition that the life of a human is better, in the sense of being intrinsically more valuable, than the life of an animal. I argue that in this he fails because in order to do successfully he would have to show not only that the life (...) of a human is preferable to that of an animal on hedonistic grounds, but also that it is in some sense nobler or more dignified to be a human, which he cannot do without tacitly presupposing non-hedonistic standards of what it means to lead a good life.

The papers collected in this volume examine moral enhancement: the idea that we should morally improve people through the manipulation of their biological constitution. Whether moral enhancement is possible or even desirable is highly controversial. Proponents argue that it is necessary if we are to address various social ills and avert catastrophic climate change. Detractors have raised a variety of concerns, some of a practical nature and others of principle. Perhaps most fundamentally, however, the proposal forces us to ask anew (...) what being moral actually means, in order for the idea of moral enhancement to make sense at all. The present collection both addresses these issues and moves the debate beyond its current parameters, bringing together authors with a wide range of perspectives and areas of expertise. Chapters variously draw on experimental psychology, social philosophy, pragmatism, Kantian and Aristotelian moral philosophy, and the ethics of care, sex, and psychedelics. (shrink)

This paper argues that the goal the proponents of radical life extension wish to attain is in fact unattainable, and that with regard to this goal, the whole project of conquering ageing and death is therefore likely to fail. What we seek to achieve is not the prolongation of life as such, but rather the prolongation of a healthy and youthful life. Yet even though it may one day be possible to prevent the body from ageing beyond a certain stage (...) , it may never be possible to arrest the ageing of the mind, which is what we desire most of all.

Climate change is one of the most urgent global problems that we face today. The causes are well understood and many solutions have been proposed; however, so far none have been successful. Ingmar Persson and Julian Savulescu have argued that this is because our moral psychology is ill-equipped to deal with global problems such as this. They propose that in order to successfully mitigate climate change we should morally enhance ourselves. In this chapter we look at their proposal to see (...) whether moral enhancement is indeed a viable solution to the climate crisis, and conclude that due to various theoretical and practical problems it most likely is not.

The question what makes us human is often treated as a question of fact. However, the term 'human' is not primarily used to refer to a particular kind of entity, but as a 'nomen dignitatis' -- a dignity-conferring name. It implies a particular moral status. That is what spawns endless debates about such issues as when human life begins and ends and whether human-animal chimeras are "partly human". Definitions of the human are inevitably "persuasive". They tell us about what is (...) important and how we should live our lives as humans, and thus help us to make sense of what we are. (shrink)

The possibility of moral bioenhancement, and the alleged need for it, have been widely discussed both in ethics journals and the media since this type of enhancement was first proposed in the Journal of Medical Ethics in 2008. Most prominently, Ingmar Persson and Julian Savulescu have argued that humans in their current condition are simply not good enough to deal effectively with the global problems we face today and that, if we want to have any hope of saving the world (...) from “ultimate harm,” we need to find ways to morally enhance people, using psychopharmaceuticals, neurostimulation, gene editing, or whatever other biological method we can think of that might do the trick. Persson and Savulescu's 2012 book on the subject, Unfit for the Future: The Need for Moral Enhancement, has very much determined the direction of the debate. However, what remains contentious is the question of whether the kind of enhancement that Persson and Savulescu envisage is really desirable and actually feasible. Earlier in 2016, two books on moral bioenhancement were published, namely John Harris's How to Be Good: The Possibility of Moral Enhancement and Harris Wiseman's The Myth of the Moral Brain: The Limits of Moral Enhancement. Harris's book focuses on the desirability of moral bioenhancement, and Wiseman's primarily on its feasibility. Both reject Persson and Savulescu's proposal and approach, but for very different reasons. (shrink)

‘What’s wrong – fundamentally wrong – with the way animals are treated (…) isn’t the pain, the suffering, isn’t the deprivation. (…) The fundamental wrong is the system that allows us to view animals as our resources, here for us – to be eaten, or surgically manipulated, or exploited for sport or money.’\n\nTom Regan made this claim 20 years ago. What he maintains is basically that the fundamental wrong is not the suffering we inflict on animals but the way we (...) look at them. What we do to them, what we believe we are allowed to do to them, is dependent on how we perceive or conceptualize them. We not only treat them as resources but prior to this we already think of them as resources, and when we look at them, all we tend to see is resources. In our perception of them they exist not for themselves but ‘for us’. But obviously it can only be fundamentally wrong in a moral sense to view them that way if it is wrong in a factual sense, that is, if animals are in fact not ‘for us’. But is it wrong? (shrink)

After showing that despite being inherently flawed the concept of dignity cannot be replaced without loss by ethical principles such as “respect for persons,” it is argued that, if dignity be not understood as dignitas, but as bonitas, which emphasizes connectedness rather than excellence and to which the proper response is not respect, but awe, there is no reason not to ascribe it to the human embryo. The question whether or not human embryos have dignity can then be answered in (...) the affirmative on the same pragmatist grounds that ultimately lead us to respect other human persons as possessors of dignity, that is, a special moral worth.

It has been argued that, due to our commitment to distributive justice and fairness, we have a moral obligation toward animals to enhance, or “uplift,” them to quasihuman status, so that they, too, can enjoy all the intellectual, social, and cultural goods that humans are capable of enjoying. In this article, I look at the underlying assumption that the life of an animal can never be as good as that of a human, not because of any external circumstances that may (...) be changed, but simply because of the restrictions imposed on him by his animal nature. This assumption is only plausible if there are objective goods that animals have no access to. Yet even if there are objective goods, they are best understood as species-relative, so that each kind of animal has its own set of goods, which are determined by its specific nature. It follows that we have no moral obligation to uplift animals on the grounds that their life is necessarily worse than ours. (shrink)

In The Imperative of Responsibility, published in German in 1979 and in English five years later, Hans Jonas introduced a new moral imperative for the technological age that runs as follows : «Act so that the effects of your action are compatible with the permanence of genuine human life». This article has two objectives: firstly to clarify what it means to live, in Jonas’ sense, a genuine human life, and secondly whether we can still live such a life if we (...) radically enhance ourselves the way transhumanists tell us we should. We use two concepts from Jonas’ thought to flesh out the notion of genuine humanity — the human condition and the idea of Man — and argue that human enhancement could indeed compromise both: a prospect to be avoided.

Genetic engineering is still considered morally wrong by a large proportion of the public. Yet many scientists are puzzled about the public concern over a technology that, in their view, promises great benefits to humans and does not seem to cause more harm to animals than other practices which are rarely questioned. In this book, Michael Hauskeller takes public fears seriously and offers the idea of 'biological integrity' as a clarifying principle which can then be analyzed to show that seemingly (...) irrational public concerns about genetic engineering are not so irrational and that a philosophically sound justification of those concerns can indeed be given.

This collection of papers aims to increase our understanding of a) what meaning in life is: how it is to be understood, what its constituents are, and how it can be properly distinguished from other features that are commonly thought to be required for a good life, such as happiness, b) in what way, if any, mortality can be said to be detrimental to a life's meaningfulness and what follows from this for the desirability of radical life extension and other (...) alterations of the present human condition, and c) in what way, if any, death and mortality can be said to be requisites or at least constituents of a meaningful life.

That twenty-first century Prometheus Dr. Nicolas Michaud and his uncannily dedicated team have stitched together sundry pieces of tissue torn from movies, TV shows, comics, and novels, and assembled these into a single bodily form with some resemblance to an intelligent being, yet possessed of disconcerting oddities, including the disturbing habit of asking strange questions:- Why do we assume that ugly is evil?- Are we responsible for what our creations do?- Was Dr. Frankenstein's creature a monster, and what makes something (...) a monster anyway?- If it's wrong to make monsters, can it really be okay to make babies?- Is God equally as guilty as Dr. Frankenstein?- Has science become a monster, or is that all down to capitalism?
