Should transhuman and posthuman persons ever be brought into existence? And if so, could they be generated in a good and loving way? This study explores how society may respond to the actual generation of new kinds of persons from ethical, philosophical, and theological perspectives. Contributors to this volume address a number of essential questions, including the ethical ramifications of generating new life, the relationships that generators may have with their creations, and how these creations may consider their generation. This collection's interdisciplinary approach traverses the philosophical writings of Aristotle, Aquinas, Kant, Nietzsche, and Heidegger, alongside theological considerations from Jewish, Christian, and Islamic traditions. It invites academics, faith leaders, policy makers, and stakeholders to think through the ethical gamut of generating posthuman and transhuman persons.

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.

Posthuman theory asks in various ways what it means to be human in a time when philosophy has become suspicious of claims about human subjectivity. Those subjects who were historically considered aberrant, and our future lives becoming increasingly hybrid show we have always been and are continuously transforming into posthumans. What are the ethical considerations of thinking the posthuman? Posthuman Ethics asks not what the posthuman is, but how posthuman theory creates new, imaginative ways of understanding relations between lives. Ethics is a practice of activist, adaptive and creative interaction which avoids claims of overarching moral structures. Inherent in thinking posthuman ethics is the status of bodies as the site of lives inextricable from philosophy, thought, experiments in being and fantasies of the future. Posthuman Ethics explores certain kinds of bodies to think new relations that offer liberty and a contemplation of the practices of power which have been exerted upon bodies. The tattooed and modified body, the body made ecstatic through art, the body of the animal as a strategy for abolitionist animal rights, the monstrous body from teratology to fabulations, queer bodies becoming angelic, the bodies of the nation of the dead and the radical ways in which we might contemplate human extinction are the bodies which populate this book creating joyous political tactics toward posthuman ethics.

The Posthuman offers both an introduction and major contribution to contemporary debates on the posthuman. Digital 'second life', genetically modified food, advanced prosthetics, robotics and reproductive technologies are familiar facets of our globally linked and technologically mediated societies. This has blurred the traditional distinction between the human and its others, exposing the non-naturalistic structure of the human. The Posthuman starts by exploring the extent to which a post-humanist move displaces the traditional humanistic unity of the subject. Rather than perceiving this situation as a loss of cognitive and moral self-mastery, Braidotti argues that the posthuman helps us make sense of our flexible and multiple identities. Braidotti then analyzes the escalating effects of post-anthropocentric thought, which encompass not only other species, but also the sustainability of our planet as a whole. Because contemporary market economies profit from the control and commodification of all that lives, they result in hybridization, erasing categorical distinctions between the human and other species, seeds, plants, animals and bacteria. These dislocations induced by globalized cultures and economies enable a critique of anthropocentrism, but how reliable are they as indicators of a sustainable future? The Posthuman concludes by considering the implications of these shifts for the institutional practice of the humanities. Braidotti outlines new forms of cosmopolitan neo-humanism that emerge from the spectrum of post-colonial and race studies, as well as gender analysis and environmentalism. The challenge of the posthuman condition consists in seizing the opportunities for new social bonding and community building, while pursuing sustainability and empowerment.

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.

Mary Anne Warren explores a theoretical question which lies at the heart of practical ethics: what are the criteria for having moral status? In other words, what are the criteria for being an entity towards which people have moral obligations? Some philosophers maintain that there is one intrinsic property—for instance, life, sentience, humanity, or moral agency. Others believe that relational properties, such as belonging to a human community, are more important. In Part I of the book, Warren argues that no single property can serve as the sole criterion for moral status; instead, life, sentience, moral agency, and social and biotic relationships are all relevant, each in a different way. She presents seven basic principles, each focusing on a property that can, in combination with others, legitimately affect an agent's moral obligations towards entities of a given type. In Part II, these principles are applied in an examination of three controversial ethical issues: voluntary euthanasia, abortion
