We face an emerging range of technologies that can be applied to our human natures with the goal of enhancing us. There are nootropic smart drugs and gene editing that influence the development of the brain. The near future promises cybernetic technologies that can be grafted onto our brains and bodies. The challenge for readers of Dialogues on Human Enhancement is to decide how to respond to these and other coming enhancement technologies. As you read these dialogues you will meet passionate advocates for a variety of responses to enhancement tech, ranging from blanket rejection to ecstatic endorsement. You’ll encounter Olen, for whom there is no such thing as too much enhancement. You’ll meet Winston, a bioconservative who fiercely but also imaginatively opposes any human enhancement. And there is the moderate Eugenie, who strives to distinguish between enhancement technologies that should and should not be accepted. As these characters philosophically engage with each other they will benefit from the supervisory presence of Sophie, the philosopher. Dialogues on Human Enhancement does not arrive at a single conclusion. Olen’s transhumanism, Eugenie’s moderation, and Winston’s bioconservatism are presented as viable and necessary views as we enter a future made uncertain by human enhancement tech. And the book also welcomes the voices of students, even – and especially – if they challenge the opinions of our age’s experts. As students join the conversations in this book, they will formulate their own views about how humanity could or should be in our Age of Human Enhancement.

Are bacteriophage T4 and the long-nosed elephant fish valuable in their own right? Nicholas Agar defends an affirmative answer to this question by arguing that anything living is intrinsically valuable. This claim challenges received ethical wisdom according to which only human beings are valuable in themselves. The resulting biocentric or life-centered morality forms the platform for an ethic of the environment.

Agar builds a bridge between the biological sciences and what he calls "folk" morality to arrive at a workable environmental ethic and a new spectrum -- a new hierarchy -- of living organisms. The book overturns common-sense moral belief as well as centuries of philosophical speculation on the exclusive moral significance of humans. Spanning several fields, including philosophy of psychology, philosophy of science, and other areas of contemporary analytic philosophy, Agar analyzes and speaks to a wide array of historic and contemporary views, from Aristotle and Kant, to E. O. Wilson, Holmes Rolston II, and Baird Callicot. The result is a challenge to prevailing definitions of value and a call for a scientifically-informed appreciation of nature.

Advances in our scientific understanding and technological power in recent decades have dramatically amplified our capacity to intentionally manipulate complex ecological and biological systems. An implication of this is that biological and ecological problems are increasingly understood and approached from an engineering perspective. In environmental contexts, this is exemplified in the pursuits of geoengineering, designer ecosystems, and conservation cloning. In human health contexts, it is exemplified in the development of synthetic biology, bionanotechnology, and human enhancement technologies. Designer Biology: The Ethics of Intensively Engineering Biological and Ecological Systems consists of thirteen chapters (twelve of them original to the collection) that address the ethical issues raised by technological intervention and design across a broad range of biological and ecological systems. Among the technologies addressed are geoengineering, human enhancement, sex selection, genetic modification, and synthetic biology. The aim of the collection is to advance and enrich our understanding of the ethical issues raised by these technologies, as well as to identify general lessons about the ethics of engineering complex biological and ecological systems that can be applied as new technologies and practices emerge. The insights that emerge will be especially valuable to students and scholars of environmental ethics, bioethics, or technology ethics.

An argument in favor of finding a place for humans (and humanness) in the future digital economy. In the digital economy, accountants, baristas, and cashiers can be automated out of employment; so can surgeons, airline pilots, and cab drivers. Machines will be able to do these jobs more efficiently, accurately, and inexpensively. But, Nicholas Agar warns in this provocative book, these developments could result in a radically disempowered humanity. The digital revolution has brought us new gadgets and new things to do with them. The digital revolution also brings the digital economy, with machines capable of doing humans' jobs. Agar explains that developments in artificial intelligence enable computers to take over not just routine tasks but also the kind of "mind work" that previously relied on human intellect, and that this threatens human agency. The solution, Agar argues, is a hybrid social-digital economy. The key value of the digital economy is efficiency. The key value of the social economy is humanness. A social economy would be centered on connections between human minds. We should reject some digital automation because machines will always be poor substitutes for humans in roles that involve direct contact with other humans. A machine can count out pills and pour out coffee, but we want our nurses and baristas to have minds like ours. In a hybrid social-digital economy, people do the jobs for which feelings matter and machines take on data-intensive work. But humans will have to insist on their relevance in a digital age.

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.

Ethical Issues in Biotechnology is the first textbook of its kind, written collaboratively by a philosopher and a biologist to provide undergraduate students with a comprehensive, accessible introduction to the ethical and scientific fundamentals of biotechnology. Engaging the ethics and the science side by side, the text addresses pressing questions in agricultural, food, and animal biotechnology; human genetics; gene therapy; human cloning; and stem cell research. A general introduction to both the moral philosophy and fundamentals of genetics is enhanced throughout the text with section-specific introductions addressing the particular philosophical and scientific challenges posed by the topic under consideration. Diagrams and drawings, study cases, liberal use of practical examples, and suggestions for further reading make the text an ideal resource for a broad range of students interested in issues and questions lying at the intersection of philosophy and genetics.

The rapid developments in technologies - especially computing and the advent of many 'smart' devices, as well as rapid and perpetual communication via the Internet - has led to a frequently voiced view which Nicholas Agar describes as 'radical optimism'. Radical optimists claim that accelerating technical progress will soon end poverty, disease, and ignorance, and improve our happiness and well-being. Agar disputes the claim that technological progress will automatically produce great improvements in subjective well-being. He argues that radical optimism 'assigns to technological progress an undeserved pre-eminence among all the goals pursued by our civilization'. Instead, Agar uses the most recent psychological studies about human perceptions of well-being to create a realistic model of the impact technology will have. Although he accepts that technological advance does produce benefits, he insists that these are significantly less than those proposed by the radical optimists, and aspects of such progress can also pose a threat to values such as social justice and our relationship with nature, while problems such as poverty cannot be understood in technological terms. He concludes by arguing that a more realistic assessment of the benefits that technological advance can bring will allow us to better manage its risks in future.
