In Defense of the Land Ethic: Essays in Environmental Philosophy brings into a single volume J. Baird Callicott’s decade-long effort to articulate, defend, and extend the seminal environmental philosophy of Aldo Leopold. A leading voice in this new field, Callicott sounds the depths of the proverbial iceberg, the tip of which is “The Land Ethic.” “The Land Ethic,” Callicott argues, is traceable to the moral psychology of David Hume and Charles Darwin’s classical account of the origin and evolution of Hume’s (...) moral sentiments. Leopold adds an ecological vision of organic nature to these foundations. How can an evolutionary and ecological environmental ethic bridge the gap between is and ought? How may wholes—species, ecosystems, and the biosphere itself—be the direct objects of moral concern? How may the intrinsic value of nonhuman natural entities and nature as a whole be justified? In addition to confronting and resolving these distinctly philosophical queries, Callicott engages in lively debate with proponents of animal liberation and rights—finally to achieve an integrated theory of animal welfare and environmental ethics. He critically discusses the land ethic that is alleged to have prevailed among traditional American Indian peoples and points toward a new and equally revolutionary environmental aesthetic. (shrink)

There is an important distinction between a person's ’initial genetic endowment’ and his ’post‐conception inputs’ such as nutrition and education. From a left‐libertarian perspective that views persons as self‐owning, children have an enforceable claim that parents should provide adequate ’post‐conception’ inputs. Moreover, with the revolution in genetic science, it is now possible to effect genetic changes without altering identity. If so, children can, in principle, claim a right against ’genetic‐disablement’.

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.

More than twenty years after its original publication, The Case for Animal Rights is an acknowledged classic of moral philosophy, and its author is recognized as the intellectual leader of the animal rights movement. In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

When we compare contemporary moral philosophy with the well-known moral systems of earlier centuries, we should be struck by the fact that a certain assumption about human well being that is now widely taken for granted was universally rejected in the past. The contemporary moral climate predisposes us to be pluralistic about the human good, whereas earlier systems of ethics embraced a conception of well being that we would now call narrow and restrictive. One way to convey the sort of (...) contrast I have in mind is to note that according to Plato and Aristotle, there is one kind of life, that of the philosopher, that represents the summit of human flourishing, and all other lives are worth leading to the extent that they approximate this ideal. Certain other ethical theories of the past were in a way more narrow than this, for whereas Plato and Aristotle maintained that many things are in themselves worthwhile, others argued that there is only one intrinsic good—pleasure according to the Epicureans, virtue according to the Stoics. By contrast, it is now widely assumed that all such approaches are too exclusive, that not only are there many types of intrinsic goods but there is no one specific kind of life—whether it is that of a philosopher or a poet or anyone else—that is the single human ideal. Even hedonism, a conception of the good that had a powerful influence in the modern period, has few contemporary proponents. A consensus has arisen in our time that there is no single ultimate good that provides the measure by which the worth of all other goods must be assessed. (shrink)

In this article I examine the proposition that severe cognitive disability is an impediment to moral personhood. Moral personhood, as I understand it here, is articulated in the work of Jeff McMahan as that which confers a special moral status on a person. I rehearse the metaphysical arguments about the nature of personhood that ground McMahan’s claims regarding the moral status of the “congenitally severely mentally retarded” (CSMR for short). These claims, I argue, rest on the view that only intrinsic (...) psychological capacities are relevant to moral personhood: that is, that relational properties are generally not relevant. In addition, McMahan depends on an argument that species membership is irrelevant for moral consideration and a contention that privileging species membership is equivalent to a virulent nationalism (these will be discussed below). In consequence, the CSMR are excluded from moral personhood and their deaths are less significant as their killing is less wrong than that of persons. To throw doubt on McMahan’s conclusions about the moral status and wrongness of killing the CSMR I question the exclusive use of intrinsic properties in the metaphysics of personhood, the dismissal of the moral importance of species membership, and the example of virulent nationalism as an apt analogy. I also have a lot to say about McMahan’s empirical assumptions about the CSMR. (shrink)

Burgess-Jackson argues that the duties we have to our companion animals are similar to the duties we have to our children. Specifically, he argues that a person who takes custody of either a nonhuman animal or a child elevates the moral status of the child or animal, endowing each with rights neither had before. These rights obligate that person to provide for the well being of the creature—animal or child—in question. This paper offers two arguments against this position. First, a (...) creature's rights rest solely on the creature's intrinsic properties. Thus, the person taking custody of a creature does not endow the creature with new rights. Rather, the custodian assumes the responsibilities associated with ensuring that the creature's rights are protected and preserved. Second, our children possess intrinsic properties and, hence, rights—most important, the right to life—that our pets lack. This difference undermines the analogy on which Burgess-Jackson's argument depends. Our pets are not like our children, as Burgess-Jackson claims. Instead, they are more akin to our slaves. (shrink)

This article argues that it is not necessary to abolish all incidents of animal ownership in order to achieve justice for them. It claims that ownership does not grant owners a right to absolute control of their property. Rather, it argues that ownership is a much more qualified concept, conveying different rights in different contexts. With this understanding of ownership in mind, the article argues that it is possible for humans to own animals and at the same time to treat (...) them justly: to recognize that they possess moral status; to assign them meaningful rights; and to consider their interests equally.

Leif Wenar examines the impact on takings scholarship of the redefinition of "property" early in the twentieth century. He argues that the Hohfeldian characterization of property as rights (instead of as tangible things) forced major scholars such as Michelman, Sax, and Epstein into extreme interpretations of the Takings Clause. This extremism is unnecessary, however, since the original objections to the idea that "property is things" are mistaken.
