In Enhancing Evolution, leading bioethicist John Harris dismantles objections to genetic engineering, stem-cell research, designer babies, and cloning and makes an ethical case for biotechnology that is both forthright and rigorous. Human enhancement, Harris argues, is a good thing--good morally, good for individuals, good as social policy, and good for a genetic heritage that needs serious improvement. Enhancing Evolution defends biotechnological interventions that could allow us to live longer, healthier, and even happier lives by, for example, providing us with immunity (...) from cancer and HIV/AIDS. Further, Harris champions the possibility of influencing the very course of evolution to give us increased mental and physical powers--from reasoning, concentration, and memory to strength, stamina, and reaction speed. Indeed, he says, it's not only morally defensible to enhance ourselves; in some cases, it's morally obligatory. In a new preface, Harris offers a glimpse at the new science and technology to come, equipping readers with the knowledge to assess the ethics and policy dimensions of future forms of human enhancement.

The human desire to acquire new capacities is as ancient as our species itself. We have always sought to expand the boundaries of our existence, be it socially, geographically, or mentally. There is a tendency in at least some individuals always to search for a way around every obstacle and limitation to human life and happiness.

Beginning with the premise that there is a fundamental biological inequality in the sexes, the author presents her classic blueprint for social revolution. Reissue. 25,000 first printing.

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.

A half-billion years ago, a few species of single-celled protozoa stumbled irreversibly from loose social interaction into a tight, specialized interdependence. They became multi-celled metazoa, and human beings are one sort. Metazoa greatly transcend their constituent cells in lifetime, abilities, experiences and even materials (like bone). New kind of beings emerged out of the interactions of the old.

A reviewer of the original edition in 1970 of "The Perfectibility of Man" well summarizes the scope and significance of this renowned work by one of the leading philosophers of the twentieth century: "Beginning with an analytic discussion of the various ways in which perfectibility has been interpreted, Professor Passmore traces its long history from the Greeks to the present day, by way of Christianity, orthodox and heterodox, the Renaissance, the Enlightenment, anarchism, utopias, communism, psychoanalysis, and evolutionary theories of man (...) and society. Both in its broad sweep and in countless supporting reflections, it is a journey through spiritual scenery of the most majestic and exhilarating kind." Thoroughly and elegantly, Passmore explores the history of the idea of perfectibility--manifest in the ideology of perfectibilism--and its consequences, which have invariably been catastrophic for individual liberty and responsibility in private, social, economic, and political life.John Passmore served for many years as a Professor of Philosophy at Australian National University.

Here a distinguished American historian challenges the belief that the eighteenth century was essentially modern in its temper. In crystalline prose Carl Becker demonstrates that the period commonly described as the Age of Reason was, in fact, very far from that; that Voltaire, Hume, Diderot, and Locke were living in a medieval world, and that these philosophers “demolished the Heavenly City of St. Augustine only to rebuild it with more up-to-date materials.” In a new foreword, Johnson Kent Wright looks at (...) the book’s continuing relevance within the context of current discussion about the Enlightenment. “Will remain a classic—a beautifully finished literary product.”—Charles A. Beard, _American Historical Review_ “_The Heavenly City of the Eighteenth-Century Philosophers _remains_ _one of the most distinctive American contributions to the historical literature on the Enlightenment.... [It] is likely to beguile and provoke readers for a long time to come.”—Johnson Kent Wright, from the foreword. (shrink)

The beginning of the modern period in the pursuit of radical human enhancement and longevity can be traced to fin-de-siècle/early twentieth-century scientific and technological optimism and therapeutic activism. The works of several authors of the period – Fedorov, Stephens, Bogdanov, Nietzsche and Finot – reveal conflicting ideological and social pathways toward the goals of human enhancement and life extension. Each author represents a particular existing social order, and his vision of human advancement may be seen as a continuation and extension (...) of that order. Therefore, the pursuit of life extension may be considered a fundamentally conservative enterprise. (shrink)

Written in 1486 by the then 23-year-old Giovanni Pico della Mirandola, the Oration on the Dignity of Man is considered a 'Manifesto for the Renaissance' and one of the most influential philosophical texts of its day, setting the tone for humanism.
