In the literature of environmental philosophy, the single most potent argument that has been made against the claim that nature may possess intrinsic value in any objective sense is the Humean thesis of projectivism and its associated view that human consciousness is the source of all values. Theorists, in one way or another, have to face up to this challenge. For instance, J. Baird Callicott upholds this Humean foundation to modern Western philosophy. However, by distinguishing between the source and locus (...) of value, he makes it possible to argue that nature is the locus of intrinsic value without at the same time compromising the thesis that human consciousness is the source of all values. On the other hand, Holmses Rolston, III, another eminent environmental philosopher, criticizes the distinction as well as challenges the Humean foundation itself. In this article, I attempt to resolve the disagreement between Callicott and Rolston over this particular distinction, thereby doing justice to the insights which each theorist, undoubtedly, has brought to bear on the issue of intrinsic value, at least as far as individual organisms is concerned. However, I am also critical of both for having failed to draw out the full implications behind certain crucial distinctions that should be made about the notion of intrinsic value itself. (shrink)

I present the foundational structure for a life-centered theory of environmental ethics. The structure consists of three interrelated components. First is the adopting of a certain ultimate moral attitude toward nature, which I call “respect for nature.” Second is a belief system that constitutes a way of conceiving of the natural world and of our place in it. This belief system underlies and supports the attitude in a way that makes it an appropriate attitude to take toward the Earth’s natural (...) ecosystems and their life communities. Third is a system of moral rules and standards for guiding our treatment of those ecosystems and life communities, a set of normative principles which give concrete embodiment or expression to the attitude of respect for nature. The theory set forth and defended here is, I hold, structurally symmetrical with a theory of human ethics based on the principle of respect for persons. (shrink)

Since its original publication in 1975, this groundbreaking work has awakened millions of concerned men and women to the shocking abuse of animals everywhere--inspiring a worldwide movement to eliminate much of the cruel and unnecessary laboratory animal experimentation of years past. In this newly revised and expanded edition, author Peter Singer exposes the chilling realities of today's "factory farms" and product-testing procedures--offering sound, humane solutions to what has become a profound environmental and social as well as moral issue. An important (...) and persuasive appeal to conscience, fairness, decency and justice, Animal Liberation is essential reading for the supporter and the skeptic alike.--From publisher description.

To hold an environmental ethic is to hold that non-human beings and states of affairs in the natural world have intrinsic value. This seemingly straightforward claim has been the focus of much recent philosophical discussion of environmental issues. Its clarity is, however, illusory. The term ‘intrinsic value’ has a variety of senses and many arguments on environmental ethics suffer from a conflation of these different senses: specimen hunters for the fallacy of equivocation will find rich pickings in the area. This (...) paper is largely the work of the underlabourer. I distinguish different senses of the concept of intrinsic value, and, relatedly, of the claim that non-human beings in the natural world have intrinsic value; I exhibit the logical relations between these claims and examine the distinct motivations for holding them. The paper is not however merely an exercise in conceptual underlabouring. It also defends one substantive thesis: that while it is the case that natural entities have intrinsic value in the strongest sense of the term, i.e., in the sense of value that exists independently of human valuations, such value does not as such entail any obligations on the part of human beings. The defender of nature’s intrinsic value still needs to show that such value contributes to the well-being of human agents. (shrink)

Linking the process of rational decision making to emotions, an award-winning scientist who has done extensive research with brain-damaged patients notes the dependence of thought processes on feelings and the body's survival-oriented regulators. 50,000 first printing.

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)

Biophilia is Edward O. Wilson's most personal book, an evocation of his own response to nature and an eloquent statement of the conservation ethic. Wilson argues that our natural affinity for life―biophilia―is the very essence of our humanity and binds us to all other living species.

Marc Hauser puts forth the theory that humans have evolved a universal moral instinct, unconsciously propelling us to deliver judgments of right and wrong independent of gender, education, and religion. Combining his cutting-edge research with the latest findings in cognitive psychology, linguistics, neuroscience, evolutionary biology, economics, and anthropology, Hauser explores the startling implications of his provocative theory vis-à-vis contemporary bioethics, religion, the law, and our everyday lives.
