As we are increasingly using new technologies to change ourselves beyond therapy and in accordance with our own desires, understanding the challenges of human enhancement has become one of the most urgent topics of the current age. This volume contributes to such an understanding by critically examining the pros and cons of our growing ability to shape human nature through technological advancements. The authors undertake careful analyses of decisive questions that will confront society as enhancement interventions using bio-, info-, neuro- and nanotechnologies become widespread in the years to come. They provide the reader with the conceptual tools necessary to address such questions fruitfully. What makes the book especially attractive is the combination of conceptual, historical and ethical approaches, rendering it highly original. In addition, the well-balanced structure allows both favourable and critical views to be voiced. Moreover, the work has a crystal clear structure. As a consequence, the book is accessible to a broad academic audience. The issues raised are of interest to a wide reflective public concerned about science and ethics, as well as to students, academics and professionals in areas such as philosophy, applied ethics, bioethics, medicine and health management.
We imagine posthumans as humans made superhumanly intelligent or resilient by future advances in nanotechnology, biotechnology, information technology and cognitive science. Many argue that these enhanced people might live better lives; others fear that tinkering with our nature will undermine our sense of our own humanity. Whoever is right, it is assumed that our technological successor will be an upgraded or degraded version of us: Human 2.0. Posthuman Life argues that the enhancement debate projects a human face onto an empty screen. We do not know what will happen and, not being posthuman, cannot anticipate how posthumans will assess the world. If a posthuman future will not necessarily be informed by our kind of subjectivity or morality the limits of our current knowledge must inform any ethical or political assessment of that future. Posthuman Life develops a critical metaphysics of posthuman succession and argues that only a truly speculative posthumanism can support an ethics that meets the challenge of the transformative potential of technology.
Biotechnologies already on the horizon will enable us to be smarter, have better memories, be stronger and quicker, have more stamina, live longer, be more resistant to diseases, and enjoy richer emotional lives. To some of us, these prospects are heartening; to others, they are dreadful. In Beyond Humanity a leading philosopher offers a powerful and controversial exploration of urgent ethical issues concerning human enhancement. These raise enduring questions about what it is to be human, about individuality, about our relationship to nature, and about what sort of society we should strive to have. Allen E. Buchanan urges that the debate about enhancement needs to be informed by a proper understanding of evolutionary biology, which has discredited the simplistic conceptions of human nature used by many opponents of enhancement. He argues that there are powerful reasons for us to embark on the enhancement enterprise, and no objections to enhancement that are sufficient to outweigh them.
New biotechnologies have propelled the question of what it means to be human – or posthuman – to the forefront of societal and scientific consideration. This volume provides an accessible, critical overview of the main approaches in the debate on posthumanism, and argues that they do not adequately address the question of what it means to be human in an age of biotechnology. Not because they belong to rival political camps, but because they are grounded in a humanist ontology that presupposes a radical separation between human subjects and technological objects. The volume offers a comprehensive mapping of posthumanist discourse divided into four broad approaches—two humanist-based approaches: dystopic and liberal posthumanism, and two non-humanist approaches: radical and methodological posthumanism. The author compares and contrasts these models via an exploration of key issues, from human enhancement, to eugenics, to new configurations of biopower, questioning what role technology plays in defining the boundaries of the human, the subject and nature for each. Building on the contributions and limitations of radical and methodological posthumanism, the author develops a novel perspective, mediated posthumanism, that brings together insights in the philosophy of technology, the sociology of biomedicine, and Michel Foucault’s work on ethical subject constitution. In this framework, technology is neither a neutral tool nor a force that alienates humanity from itself, but something that is always already part of the experience of being human, and subjectivity is viewed as an emergent property that is constantly being shaped and transformed by its engagements with biotechnologies. Mediated posthumanism becomes a tool for identifying novel ethical modes of human experience that are richer and more multifaceted than current posthumanist perspectives allow for. The book will be essential reading for students and scholars working on ethics and technology, philosophy of technology, poststructuralism, technology and the body, and medical ethics.
Improving human characteristics goes beyond compensating for an impairment. This book explores the rich and complex relationship between enhancement and impairment, showing that the study of disability offers new ways of thinking about the social and ethical implications of improving the human condition.
This book presents a collection of chapters, which address various contexts and challenges of the idea of human enhancement for the purposes of human space missions. The authors discuss pros and cons of mostly biological enhancement of human astronauts operating in hostile space environments, but also ethical and theological aspects are addressed. In contrast to the idea and program of human enhancement on Earth, human enhancement in space is considered a serious and necessary option. This book aims at scholars in the following fields: ethics and philosophy, space policy, public policy, as well as biologists and psychologists.
Is a baby whose personality has been chosen from a gene supermarket still a human? If we choose what we create what happens to morality? Is this the end of human nature? The dramatic advances in DNA technology over the last few years are the stuff of science fiction. It is now not only possible to clone human beings it is happening. For the first time since the creation of the earth four billion years ago, or the emergence of mankind 10 million years ago, people will be able to choose their children's' sex, height, colour, personality traits and intelligence. It will even be possible to create 'superhumans' by mixing human genes with those of other animals for extra strength or longevity. But is this desirable? What are the moral and political consequences? Will it mean anything to talk about 'human nature' any more? Is this the end of human beings? Our Posthuman Future is a passionate analysis of the greatest political and moral problem ever to face the human race.
We humans can enhance some of our mental and physical abilities above the normal upper limits for our species with the use of particular drug therapies and medical procedures. We will be able to enhance many more of our abilities in more ways in the near future. Some commentators have welcomed the prospect of wide use of human enhancement technologies, while others have viewed it with alarm, and have made clear that they find human enhancement morally objectionable. The Ethics of Human Enhancement examines whether the reactions can be supported by articulated philosophical reasoning, or perhaps explained in terms of psychological influences on moral reasoning. An international team of ethicists refresh the debate with new ideas and arguments, making connections with scientific research and with related issues in moral philosophy.
A cross-disciplinary approach is offered to consider the challenge of emerging technologies designed to enhance human bodies and minds. Perspectives from philosophy, ethics, law, and policy are applied to a wide variety of enhancements, including integration of technology within human bodies, as well as genetic, biological, and pharmacological modifications. Humans may be permanently or temporarily enhanced with artificial parts by manipulating (or reprogramming) human DNA and through other enhancement techniques (and combinations thereof). We are on the cusp of significantly modifying (and perhaps improving) the human ecosystem. This evolution necessitates a continuing effort to re-evaluate current laws and, if appropriate, to modify such laws or develop new laws that address enhancement technology. A legal, ethical, and policy response to current and future human enhancements should strive to protect the rights of all involved and to recognize the responsibilities of humans to other conscious and living beings, regardless of what they look like or what abilities they have (or lack). A potential ethical approach is outlined in which rights and responsibilities should be respected even if enhanced humans are perceived by non-enhanced (or less-enhanced) humans as “no longer human” at all.
An argument that achieving millennial life spans or monumental intellects will destroy values that give meaning to human lives. Proposals to make us smarter than the greatest geniuses or to add thousands of years to our life spans seem fit only for the spam folder or trash can. And yet this is what contemporary advocates of radical enhancement offer in all seriousness. They present a variety of technologies and therapies that will expand our capacities far beyond what is currently possible for human beings. In Humanity's End, Nicholas Agar argues against radical enhancement, describing its destructive consequences. Agar examines the proposals of four prominent radical enhancers: Ray Kurzweil, who argues that technology will enable our escape from human biology; Aubrey de Grey, who calls for anti-aging therapies that will achieve “longevity escape velocity”; Nick Bostrom, who defends the morality and rationality of enhancement; and James Hughes, who envisions a harmonious democracy of the enhanced and the unenhanced. Agar argues that the outcomes of radical enhancement could be darker than the rosy futures described by these thinkers. The most dramatic means of enhancing our cognitive powers could in fact kill us; the radical extension of our life span could eliminate experiences of great value from our lives; and a situation in which some humans are radically enhanced and others are not could lead to tyranny of posthumans over humans.
