Traditionally, species have been treated as classes. In fact they may be considered individuals. The logical term “individual” has been confused with a biological synonym for “organism.” If species are individuals, then: 1) their names are proper, 2) there cannot be instances of them, 3) they do not have defining properties, 4) their constituent organisms are parts, not members. “ Species " may be defined as the most extensive units in the natural economy such that reproductive competition occurs among their (...) parts. Species are to evolutionary theory as firms are to economic theory: this analogy resolves many issues, such as the problems of “reality” and the ontological status of nomenclatorial types. (shrink)

Environmental Ethics is a systematic account of values carried by the natural world, coupled with an inquiry into duties toward animals, plants, species, and ecosystems. A comprehensive philosophy of nature is illustrated by and integrated with numerous actual examples of ethical decisions made in encounters with fauna and flora, endangered species, and threatened ecosystems. The ethics developed is informed throughout by ecological science and evolutionary biology, with attention to the logic of moving from what is in nature to what ought (...) to be. The ethical theory is applied in detail to social, public, and business policy. Written in an engaging style, using diagrams and figures as well as numerous case studies, Environmental Ethics prods the reader into concrete application and invites reader participation in the ethical discussions. The ethics concludes by exploring the historical experiences of personal residence in a surrounding environment. Here is an adventure into what it means to live as responsible human beings in the community of life on Earth. In the series Ethics and Action, edited by Tom Regan. (shrink)

What rational justification is there for conceiving of all living things as possessing inherent worth? In _Respect for Nature_, Paul Taylor draws on biology, moral philosophy, and environmental science to defend a biocentric environmental ethic in which all life has value. Without making claims for the moral rights of plants and animals, he offers a reasoned alternative to the prevailing anthropocentric view--that the natural environment and its wildlife are valued only as objects for human use or enjoyment. _Respect for Nature_ (...) provides both a full account of the biological conditions for life--human or otherwise--and a comprehensive view of the complex relationship between human beings and the whole of nature. This classic book remains a valuable resource for philosophers, biologists, and environmentalists alike--along with all those who care about the future of life on Earth. A new foreword by Dale Jamieson looks at how the original 1986 edition of _Respect for Nature_ has shaped the study of environmental ethics, and shows why the work remains relevant to debates today.

This paper critically examines the biology of species identity and the morality of crossing species boundaries in the context of emerging research that involves combining human and nonhuman animals at the genetic or cellular level. We begin with the notion of species identity, particularly focusing on the ostensible fixity of species boundaries, and we explore the general biological and philosophical problem of defining species. Against this backdrop, we survey and criticize earlier attempts to forbid crossing species boundaries in the creation (...) of novel beings. We do not attempt to establish the immorality of crossing species boundaries, but we conclude with some thoughts about such crossings, alluding to the notion of moral confusion regarding social and ethical obligations to novel interspecies beings.

There is an ongoing debate in animalethics on the meaning and scope of animalwelfare. In certain broader views, leading anatural life through the development of naturalcapabilities is also headed under the conceptof animal welfare. I argue that a concern forthe development of natural capabilities of ananimal such as expressed when living freelyshould be distinguished from the preservationof the naturalness of its behavior andappearance. However, it is not always clearwhere a plea for natural living changes overinto a plea for the preservation (...) of theirnaturalness or wildness. In the first part ofthis article, I examine to what extent theconcerns for natural living meet ``theexperience requirement.'' I conclude that someof these concerns go beyond welfare. In thesecond part of the article. I ask whether wehave moral reasons to respect concernsfor the naturalness of an animal's living thattranscend its welfare. I argue that the moralrelevance of such considerations can be graspedwhen we see animals as entities bearingnon-moral intrinsic values. In my view the``natural'' appearance and behavior of an animalmay embody intrinsic values. Caring for ananimal's naturalness should then be understoodas caring for such intrinsic values. Intrinsicvalues provide moral reasons for action iffthey are seen as constitutive of the good lifefor humans. I conclude by reinterpreting,within the framework of a perfectionist ethicaltheory, the notion of indirect dutiesregarding animals, which go beyond andsupplement the direct duties towardsanimals.

Genetic modification leads to several important moral issues. Up until now they have mainly been discussed from the viewpoint that only individual living beings, above all animals, are morally considerable. The standpoint that also collective entities such as species belong to the moral sphere have seldom been taken into account in a more thorough way, although it is advocated by several important environmental ethicists. The main purpose of this article is to analyze in more detail than often has been done (...) what the practical consequences of this ethical position would be for the use of genetic engineering on animals and plants. The practical consequences of the holistic standpoint (focused on collective entities) of Holmes Rolston, III, is compared with the practical consequences of the individualistic standpoints (focused on individual living beings) of Bernard E. Rollin and Philipp Balzer, Klaus Peter Rippe, and Peter Schaber, respectively. The article also discusses whether the claim that species are morally considerable is tenable as a foundation for policy decisions on genetic engineering. (shrink)

This work defends an interrelated set of theses in value-theory, normative ethics and meta-ethics. The three Parts correspond to these three areas. Part One (Value) defends a biocentric theory of moral standing, and then the coherence and objectivity of belief in intrinsic value, despite recent objections. Intrinsic value is located in the flourishing of living creatures; specifically, a neo-Aristotelian, species-relative account is supplied of wellbeing or flourishing, in terms of the development of the essential capacities of one's species. There follows (...) a theory of priorities, or of relative intrinsic value, in which the satisfaction of basic needs takes priority over other needs and over wants, and the interests of complex and sophisticated creatures over those of others, where they are at stake. Part Two defends a practice-consequentialist theory of the criteria of rightness and of obligation, which leaves room for supererogation, underpins our intuitions about justice, commends population growth only where it is genuinely desirable, and responds better than act-consequentialism to objections like that concerned with the separateness of persons. Part Three sifts meta-ethical theories, rejects moral relativism, and defends a cognitivist and naturalist meta-ethic. In defending analytical naturalism, it takes into account the latest literature on supervenience. By responding to recent discussions, this study supersedes my _Theory of Value and Obligation_ (1987). It is equipped with detailed end-notes and an ample bibliography, which could prove a research tool of itself. (shrink)

Through the process of domestication the genetic make-up of farm animals can be changed by means of either selective breeding or genetic engineering. This paper is about the ethical limits to such genetic changes. It is suggested that the ethical significance of domestication has become clear recently in the light of genetic engineering, but that the problem has been there all along. Two ethical approaches to domestication are presented, genetic integrity and animal welfare. It is argued that the welfare approach (...) is superior. Finally, five ethical hypotheses based on the welfare approach are presented. (shrink)

Suppose “chicken” eggs could be produced by quasi‐chickens—genetically engineered humps of living chicken‐flesh that do nothing but lay eggs. Would there be anything amiss with that? Animal ethicists invoke the notion of animal integrity in order to give intellectual content to the intuition that there would be. On inspection, ‘integrity’ isn't everything its proponents want it to be. Yet there's enough in it to make reasoned argument possible.

This book is a philosophically sophisticated and scientifically well-informed discussion of the moral and social issues raised by genetically engineering animals, a powerful technology which has major implications for society. Unlike other books on this emotionally charged subject, the author attempts to inform, not inflame, the reader about the real problems society must address in order to manage this technology. Bernard Rollin is both a professor of philosophy, and physiology and biophysics, and writes from a uniquely well-informed perspective on this (...) topic. The style is non-technical and anecdotal and will ensure that the book can be used on a wide range of courses on bioethics, biotechnology, veterinary medicine and public policy. The book could also appeal to a general, non-academic reader with a serious interest in genetic engineering. (shrink)

Bovine growth hormone is a protein that occurs naturally in cattle. A chain of 190 amino acids, bGH is produced by the pituitary gland and helps to regulate a cow’s lactational cycle; generally speaking and up to a certain point, the more bGH a cow has, the more milk she gives. Using the techniques of genetic engineering, researchers at Monsanto Company have isolated the gene that produces the protein and devised low-cost techniques to manufacture it. Bacteria are placed into fermentation (...) chambers where they multiply rapidly; lab technicians then extract and purify the final product, which is identical to the naturally occurring protein in 189 of the 190 amino acids; and the product is then injected into cows.
