Kass shows how the promise and the peril of our time are inextricably linked with the promise and the peril of modern science. The relation between the pursuit of knowledge and the conduct of life—between science and ethics, each broadly conceived—has in recent years been greatly complicated by developments in the science of life. This book examines the ethical questions involved in prenatal screening, in vitro fertilization, artificial life forms, and medical care, and discusses the role of human beings in nature.

A collection of twenty-eight essays, five previously unpublished, grouped into nine categories: Philosophy, Natural Selection, Adaptation, Darwin, Diversity, Species, Speciation, Macroevolution, and Historical Perspective. The book, Ernst Mayr notes in the Foreword, is an attempt "to strengthen the bridge between biology and philosophy, and point to the new direction in which a new philosophy of biology will move."

This lucidly written book examines the social and political significance of the natural sciences through a detailed and original account of science as an interpretive social practice.

Most American young people, like their ancestors, harbor desires for a worthy life: a life of meaning, a life that makes sense. But they are increasingly confused about what such a life might look like, and how they might, in the present age, be able to live one. With a once confident culture no longer offering authoritative guidance, the young are now at sea—regarding work, family, religion, and civic identity. The true, the good, and the beautiful have few defenders, and the higher cynicism mocks any innocent love of wisdom or love of country. We are supercompetent regarding efficiency and convenience; we are at a loss regarding what it’s all for. Yet because the old orthodoxies have crumbled, our “interesting time” paradoxically offers genuine opportunities for renewal and growth. The old Socratic question “How to live?” suddenly commands serious attention. Young Americans, if liberated from the prevailing cynicism, will readily embrace weighty questions and undertake serious quests for a flourishing life. All they (and we) need is encouragement. This book provides that necessary encouragement by illuminating crucial—and still available—aspects of a worthy life, and by defending them against their enemies. With chapters on love, family, and friendship; human excellence and human dignity; teaching, learning, and truth; and the great human aspirations of Western civilization, it offers help to both secular and religious readers, to people who are looking on their own for meaning and to people who are looking to deepen what they have been taught or to square it with the spirit of our times.

The Forest Service stumbled in responding to a wave of lawsuits from environmental groups in the late 20th Century--a phenomenon best symbolized by the spotted owl controversy that shut down logging on public forests in the Pacific Northwest in the 1990s. The agency was brought to its knees, pitted between a powerful timber industry that had been having its way with the national forests for decades, and organized environmentalists who believed public lands had been abused and deserved better stewardship. Toward a Natural Forest offers an insider's view of this tumultuous time in the history of the Forest Service, presenting twin tales of transformation, both within the agency and within the author's evolving environmental consciousness. Drawing on the author's personal experience and his broad professional knowledge, Toward a Natural Forest illuminates the potential of the Forest Service to provide strong leadership in global conservation efforts. Those interested in our public lands--environmentalists, natural resource professionals, academics, and historians--will find Jim Furnish's story deeply informed, thought-provoking, and ultimately inspiring.

In this forcefully argued book, the leading evolutionary theorist of language draws on evidence from evolutionary biology, genetics, physical anthropology, anatomy, and neuroscience, to provide a framework for studying the evolution of human language and cognition. Philip Lieberman argues forcibly that the widely influential theories of language's development, advanced by Chomskian linguists and cognitive scientists, especially those that postulate a single dedicated language "module," "organ," or "instinct," are inconsistent with principles and findings of evolutionary biology and neuroscience. He argues that the human neural system in its totality is the basis for the human language ability, for it requires the coordination of neural circuits that regulate motor control with memory and higher cognitive functions. Pointing out that articulate speech is a remarkably efficient means of conveying information, Lieberman also highlights the adaptive significance of the human tongue. Fully human language involves the species-specific anatomy of speech, together with the neural capacity for thought and movement. In Lieberman's iconoclastic Darwinian view, the human language ability is the confluence of a succession of separate evolutionary developments, jury-rigged by natural selection to work together for an evolutionarily unique ability.

"The classic and recent essays gathered here will challenge scholars in the natural sciences, philosophy, sociology, anthropology, and women's studies to examine the role of racism in the construction and application of the sciences. Harding... has also created a useful text for diverse classroom settings." -- Library Journal "A rich lode of readily accessible thought on the nature and practice of science in society. Highly recommended." -- Choice "This is an excellent collection of essays that should prove useful in a wide range of STS courses." -- Science, Technology, and Society "... important and provocative... "Â -- The Women's Review of Books "The timeliness and utility of this large interdisciplinary reader on the relation of Western science to other cultures and to world history can hardly be overemphasized. It provides a tremendous resource for teaching and for research... "Â -- Ethics "Excellent." -- The Reader's Review "Sandra Harding is an intellectually fearless scholar. She has assembled a bold, impressive collection of essays to make a volume of illuminating power. This brilliantly edited book is essential reading for all who seek understanding of the multicultural debates of our age. Never has a book been more timely." -- Darlene Clark Hine These authors dispute science's legitimation of culturally approved definitions of race difference -- including craniology and the measurement of IQ, the notorious Tuskegee syphilis experiments, and the dependence of Third World research on First World agendas.

How can human-level artificial intelligence be achieved? What are the potential consequences? This book describes a research approach toward achieving human-level AI, combining a doctoral thesis and research papers by the author. The research approach, called TalaMind, involves developing an AI system that uses a 'natural language of thought' based on the unconstrained syntax of a language such as English; designing the system as a collection of concepts that can create and modify concepts to behave intelligently in an environment; and using methods from cognitive linguistics for multiple levels of mental representation. Proposing a design-inspection alternative to the Turing Test, these pages discuss 'higher-level mentalities' of human intelligence, which include natural language understanding, higher-level forms of learning and reasoning, imagination, and consciousness. Dr. Jackson gives a comprehensive review of other research, addresses theoretical objections to the proposed approach and to achieving human-level AI in principle, and describes a prototype system that illustrates the potential of the approach. This book discusses economic risks and benefits of AI, considers how to ensure that human-level AI and superintelligence will be beneficial for humanity, and gives reasons why human-level AI may be necessary for humanity's survival and prosperity.

Today biological science is rising on a wall of worry. No other science has advanced more dramatically during the past several decades or yielded so many palpable improvements in human welfare. Yet, none except nuclear physics has aroused greater apprehensions among the general public and leaders in such diverse fields as religion, the humanities, and government. In this engaging book, Leon R. Kass, the noted teacher, scientist, humanist, and chairman of the President's Council on Bioethics, and James Q. Wilson, the preeminent political scientist to whom four United States presidents have turned for advice on crime, drug abuse, education, and other crises in American life, explore the ethics of human cloning, reproductive technology, and the teleology of human sexuality. Although in their lively dialgoue both authors share a fundamental distrust of the notion of human cloning, they base their resistance on different views of the role of sexual reproduction and the role of the family. Professor Kass contends that in vitro fertilization and other assisted reproudction technologies that place the origin of human life in human hands have eroded the respect for the mystery of sexuality and human renewal. Professor Wilson, in contrast, asserts that whether a human life is created naturally or artificially is immaterial as long as the child is raised by loving parents in a two-parent family and is not harmed by the means of its conception. This accessible volume promises to inform the public policy debate over the permissible conduct of genetic research and the permissible uses of its discoveries.
