Douglas proposes a new ideal in which values serve an essential function throughout scientific inquiry, but where the role values play is constrained at key points, protecting the integrity and objectivity of science.

This is an important book precisely because there is none other quite like it.

What Is Biodiversity? is a theoretical and conceptual exploration of the biological world and how diversity is valued. Maclaurin and Sterelny explore not only the origins of the concept of biodiversity, but also how that concept has been shaped by ecology and more recently by conservation biology. They explain the different types of biodiversity important in evolutionary theory, developmental biology, ecology, morphology and taxonomy and conclude that biological heritage is rich in not just one biodiversity but many. Maclaurin and Sterelny (...) also explore the case for the conservation of these biodiversities using option value theory, a tool borrowed from economics. (shrink)

"It has long been thought that science is our best hope for realizing objective knowledge, but that, to deliver on this promise, it must be free of the influence of any values that are not purely epistemic. As recent work in philosophy, history, and social studies of science shows, however, things are not so simple. The contributors to this volume ask where and how nonepistemic values are involved in science; they explore the roles these values play at the heart of (...) science, in the assessment of evidence and explanations, and they examine the implications this has for ideals of objectivity."--BOOK JACKET.

"At places distant from where you are, but also uncomfortably close," writes David Takacs, "a holocaust is under way. People are slashing, hacking, bulldozing, burning, poisoning, and otherwise destroying huge swaths of life on Earth at a furious pace." And a cadre of ecologists and conservation biologists has responded, vigorously promoting a new definition of nature: biodiversity --advocating it in Congress and on the Tonight Show; whispering it into the ears of foreign leaders redefining the boundaries of science and politics, (...) ethics and religion, nature and our ideas of nature. These scientists have infused the environmental movement with new focus and direction, but by engaging in such activities, they jeopardize the societal trust that allows them to be public spokespersons for nature in the first place. The Idea of Biodiversity analyzes what biodiversity represents to the biologists who operate in broader society on its behalf, drawing on in-depth interviews with the scientists most active today in the mission to preserve biodiversity, including Peter Raven, Thomas Lovejoy, Jane Lubchenco, and Paul Ehrlich. Takacs explores how and why these biologists shaped the concept of biodiversity and promoted it to society at large--examining their definitions of biodiversity their opinions about spirituality and its role in scientific work the notion of biodiversity as something of intrinsic value and their views on biophilia, E. O. Wilson's idea that humans are genetically predisposed to love nature. Takacs also looks at the work of twentieth-century forerunners of today's conservation biologists--Aldo Leopold, Charles S. Elton, Rachel Carson, David Ehrenfeld--and points out their contributions to the current debates. He takes readers to Costa Rica, where a group of scientists is using biodiversity to remake nature and society. And in an extended section, he profiles the thoughts and work of E. O. Wilson. "When I'm asked, 'should we save this species orthat species, or this place or that place?' the answer is always 'Yes!' with an exclamation point. Because it's obvious. And if you ask me to justify it, then I switch into a more cognitive consciousness and can start giving you reasons, economic reasons, aesthetic reasons. They're all dualistic, in a sense. But the feeling that underlies it is that 'yes!' And that 'yes!' comes out of the affirmation of being part of it all, being part of this whole evolutionary process. And agreeing with Arne Naess that each species, each entity, should be allowed to continue its evolution and to live out its destiny... just do its thing, as we say. Why not? And the 'why not?' is there's too many people."--Michael E. Soule, from an interview in The Idea of Biodiversity "An important contribution, a first distanced examination of a critical, modern topic by a scholarly, honest broker."--E. O. Wilson, Harvard University. (shrink)

This paper analyzes the concept of biodiversity in conservation biology and assesses potential methods for its measurement.

[D]iversity is rather like an optical illusion. The more it is looked at, the less clearly defined it appears to be and viewing it from different angles can lead to different perceptions of what is involved.Magurran The complexity of the biodiversity concept does not only mirror the natural world it supposedly represents; it is that plus the complexity of human interactions with the natural world, the inextricable skein of our values and its value, of our inability to separate our concept (...) of a thing from the thing itself. Don't know what biodiversity is? You can't.Takacs INTRODUCTIONThe neologism “biodiversity” entered the vocabularies of science, bioethics, the media, and the environmentally aware public during the 1980s; its longer version, “biological diversity,” has been in use since the late 1970s. After the National Forum on BioDiversity in Washington, D.C. in 1986 and the publication of the proceedings of that conference, use of the term “biodiversity” increased very rapidly. The number of scientific publications on biodiversity issues has grown exponentially since the late 1980s and currently exceeds 3,000 per year. The term has also quickly gained popularity outside the scientific realm, and has become a household word widely used by politicians, the media, and at least to some extent the general public.

The article considers how the preservation of biodiversity is morally justified in some of the key texts on environmental ethics, i.e. whether or not biodiversity can be justified as a moral end in itself. The views are classified according to the criteria which they hold to be the ultimate moral beneficiaries; positions are named as anthropocentrism, biocentrism and ecocentrism. In general, they are not in favor of regarding biodiversity as intrinsically valuable, but think its moral value as derivative. This means (...) that the myriad characters of life on Earth are to be maintained as diverse because of their instrumental value for the constituents. It seems that Naess's deep ecology is the only major position that argues for biodiversity's intrinsic value, but this view has proved to be problematic. (shrink)

This book explores the epistemological and ethical issues at the foundations of environmental philosophy, emphasising the conservation of biodiversity. Sahota Sarkar criticises attempts to attribute intrinsic value to nature and defends an anthropocentric position on biodiversity conservation based on an untraditional concept of transformative value. Unlike other studies in the field of environmental philosophy, this book is as much concerned with epistemological issues as with environmental ethics. It covers a broad range of topics, including problems of explanation and prediction in (...) traditional ecology and how individual-based models and Geographic Information Systems technology is transforming ecology. Introducing a brief history of conservation biology, Sarkar analyses the consensus framework for conservation planning through adaptive management. He concludes with a discussion of directions for theoretical research in conservation biology and environmental philosophy. (shrink)

Are any nonhuman animals conscious? Why, if at all, should we strive to conserve natural environments? In what sense are we parts of nature? In this book, Simon James draws on a range of philosophical and literary sources to develop original answers to these and other questions, setting out a refreshingly new approach to environmental philosophy"--Provided by publisher.
