Should there be limits to the human alteration of the natural world? Through a study of debates about the environment, agricultural biotechnology, synthetic biology, and human enhancement, Gregory E. Kaebnick argues that such moral concerns about nature can be legitimate but are also complex, contestable, and politically limited.
How Cold War America came to attribute human evolutionary success to our species' unique capacity for murder After World War II, the question of how to define a universal human nature took on new urgency. Creatures of Cain charts the rise and precipitous fall in Cold War America of a theory that attributed man’s evolutionary success to his unique capacity for murder. Drawing on a wealth of archival materials and in-depth interviews, Erika Lorraine Milam reveals how the scientists who advanced this “killer ape” theory capitalized on an expanding postwar market in intellectual paperbacks and widespread faith in the power of science to solve humanity’s problems, even to answer the most fundamental questions of human identity. The killer ape theory spread quickly from colloquial science publications to late-night television, classrooms, political debates, and Hollywood films. Behind the scenes, however, scientists were sharply divided, their disagreements centering squarely on questions of race and gender. Then, in the 1970s, the theory unraveled altogether when primatologists discovered that chimpanzees also kill members of their own species. While the discovery brought an end to definitions of human exceptionalism delineated by violence, Milam shows how some evolutionists began to argue for a shared chimpanzee-human history of aggression even as other scientists discredited such theories as sloppy popularizations. A wide-ranging account of a compelling episode in American science, Creatures of Cain argues that the legacy of the killer ape persists today in the conviction that science can resolve the essential dilemmas of human nature.
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 provocative new account of how morality evolved What is morality? Where does it come from? And why do most of us heed its call most of the time? In Braintrust, neurophilosophy pioneer Patricia Churchland argues that morality originates in the biology of the brain. She describes the "neurobiological platform of bonding" that, modified by evolutionary pressures and cultural values, has led to human styles of moral behavior. The result is a provocative genealogy of morals that asks us to reevaluate the priority given to religion, absolute rules, and pure reason in accounting for the basis of morality. Moral values, Churchland argues, are rooted in a behavior common to all mammals—the caring for offspring. The evolved structure, processes, and chemistry of the brain incline humans to strive not only for self-preservation but for the well-being of allied selves—first offspring, then mates, kin, and so on, in wider and wider "caring" circles. Separation and exclusion cause pain, and the company of loved ones causes pleasure; responding to feelings of social pain and pleasure, brains adjust their circuitry to local customs. In this way, caring is apportioned, conscience molded, and moral intuitions instilled. A key part of the story is oxytocin, an ancient body-and-brain molecule that, by decreasing the stress response, allows humans to develop the trust in one another necessary for the development of close-knit ties, social institutions, and morality. A major new account of what really makes us moral, Braintrust challenges us to reconsider the origins of some of our most cherished values.
In this historic 1971 debate, two of the twentieth century’s most influential thinkers discuss whether there is such a thing as innate human nature. In 1971, at the height of the Vietnam War and at a time of great political and social instability, two of the world’s leading intellectuals, Noam Chomsky and Michel Foucault, were invited by Dutch philosopher Fons Elders to debate an age-old question: Is there such a thing as “innate” human nature independent of our experiences and external influences? The resulting dialogue is one of the most original, provocative, and spontaneous exchanges to have occurred between contemporary philosophers. Above all, their discussion serves as a concise introduction to their two opposing theories. What begins as a philosophical argument rooted in linguistics (Chomsky) and the theory of knowledge (Foucault), soon evolves into a broader discussion encompassing a wide range of topics, from science, history, and behaviorism to creativity, freedom, and the struggle for justice in the realm of politics. In addition to the debate itself, this volume features a newly written introduction by noted Foucault scholar John Rajchman and includes substantial additional texts by Chomsky and Foucault. “[Chomsky is] arguably the most important intellectual alive.” —The New York Times “Foucault . . . leaves no reader untouched or unchanged.” —Edward Said
Enquiry concerning the principles of morals / Hume, David, 1711-1776.
Is there a shared nature common to all human beings? What essential qualities might define this nature? These questions are among the most widely discussed topics in the history of philosophy and remain subjects of perennial interest and controversy. The Nature of Human Persons offers a metaphysical investigation of the composition of the human essence. For a human being to exist, does it require an immaterial mind, a physical body, a functioning brain, a soul? Jason Eberl also considers the criterion of identity for a developing human being—that is, what is required for a human being to continue existing as a person despite undergoing physical and psychological changes over time? Eberl's investigation presents and defends a theoretical perspective from the thirteenth-century philosopher and theologian Thomas Aquinas. Advancing beyond descriptive historical analysis, this book places Aquinas’s account of human nature into direct comparison with several prominent contemporary theories: substance dualism, emergentism, animalism, constitutionalism, four-dimensionalism, and embodied mind theory. These theories inform various conclusions regarding when human beings first come into existence—at conception, during gestation, or after birth—and how we ought to define death for human beings. Finally, each of these viewpoints offers a distinctive rationale as to whether, and if so how, human beings may survive death. Ultimately, Eberl argues that the Thomistic account of human nature addresses the matters of human nature and survival in a much more holistic and desirable way than the other theories and offers a cohesive portrait of one’s continued existence from conception through life to death and beyond.
