The volume documents, and makes an original contribution to, an astonishing period in twentieth-century philosophy_the progress of Arne Naess's ecophilosophy from its inception to the present. It includes Naess's most crucial polemics with leading thinkers, drawn from sources as diverse as scholarly articles, correspondence, TV interviews and unpublished exchanges. The book testifies to the skeptical and self-correcting aspects of Naess's vision, which has deepened and broadened to include third world and feminist perspectives. Philosophical Dialogues is an essential addition to the literature on environmental philosophy

Human beings are, as far as we know, the only animals to have moral concerns and to adopt moralities, but it would be a mistake to be misled by this fact into thinking that humans are also the only proper objects of moral consideration. I argue that we ought to allow even nonliving things a significant moral status, thus denying the condusion of much contemporary moral thinking. First, I consider the possibilityof giving moral consideration to nonliving things. Second, I put forward grounds which justify this extension of morality beyond its conventional boundarles. Third, I argue that natural objects have a status different from a special dass of artifacts -works of art. Fourth, I discuss the notion of interest, and fifth I look brietly at the status of natural systems and at ways we might link the proposed extension of moral considerability with the rest of our moral thinking.

Cost-benefit analysis makes the assumption that everything from consumer goods to endangered species may in principle be given a value by which its worth can be compared with that of anything else, even though the actual measurement of such value may be difficult in practice. The assumption is shown to fail, even in simple cases, and the analysis to be incapable of taking into account the transformative value of new experiences. Several kinds of value are identified, by no means all commensurable with one another – a situation with which both economics and contemporary ethical theory must come to terms. A radical moral pluralism is recommended as in no way incompatible with the requirements of rationality, which allows that the business of living decently involves many kinds of principles and various sorts of responsibilities. In environmental ethics, pluralism offers the hope of reconciling various rival theories, even if none of them is universally applicable

This book sets out a new theory of the unity of objects. The author introduces the reader to the central problems faced by philosophical accounts of identity, problems which can, to a large extent, be solved using the theory developed in the book. In his consideration of the vexed issue of personal identity, the author argues that in our everyday thinking about persons we merge radically different kinds of notions. He suggests that our assessment of sameness of person is not founded on any determinate concept of person. Many central topics in epistemology and metaphysics are addressed in the course of the book and the author provides an original examination of each: the nature of physical objects, the metaphysics of possible worlds, the meaning of continuity in space and time and the nature of philosophical theorizing itself. The book is written in non-technical language and so will be of interest to the non-specialist philosopher
