At the heart of ethics reside the concepts of good and bad; they are at work when we assess whether a person is virtuous or vicious, an act right or wrong, a decision defensible or indefensible, a goal desirable or undesirable. But there are many varieties of goodness and badness. At their core lie intrinsic goodness and badness, the sort of value that something has for its own sake. It is in virtue of intrinsic value that other types of value may be understood, and hence that we can begin to come to terms with questions of virtue and vice, right and wrong, and so on. This book investigates the nature of intrinsic value: just what it is for something to be valuable for its own sake, just what sort of thing can have such value, just how such a value is to be computed. In the final chapter, the fruits of this investigation are applied to a discussion of pleasure, pain, and displeasure and also of moral virtue and vice, in order to determine just what value lies within these phenomena.

Are bacteriophage T4 and the long-nosed elephant fish valuable in their own right? Agar defends an affirmative answer to this question by arguing that anything living is intrinsically valuable. The result is a challenge to prevailing definitions of value and a call for a scientifically-informed appreciation of nature.

An innovative and concise exploration of the foundations of ethics.

What is intrinsic value? What is the origin of value? Are people always superior to nature? This book is a philosophical analysis of the human relationship to the non-human world. It is a pioneering study of the philosophy of nature-conservation in relation to the discussion of intrinsic value. Vilkka develops a naturalistic or naturocentric theory of value that is based on ethical extensionism and pluralism. Vilkka analyzes natural values and environmental attitudes: zoocentrism, biocentrism, and ecocentrism. This book forms a taxonomy for nature having intrinsic value. The theory of intrinsic value is based on naturocentric and naturogenic values. The book questions the thesis of weak anthropocentrism that denies the existence of naturogenic values. In Vilkka's theory, animals and nature are the origin of value. She defends the existence of zoogenic and biogenic values in the non-human world and discusses the possibility of ecogenic value, nature as a whole having value independent of human or animal minds. Vilkka analyzes the goodness and rights of nature, the problem of priorities, and ecological humanism. A naturocentric recommendation is that the well-being of animals and nature should have priority over human values at least in some real decision contexts. Ecological humanism recommends an attitude of respect for people, animals, and nature. The book includes an extensive glossary, index, and bibliography.

Recent Work on Intrinsic Value brings together for the first time many of the most important and influential writings on the topic of intrinsic value to have appeared in the last half-century. During this period, inquiry into the nature of intrinsic value has intensified to such an extent that at the moment it is one of the hottest topics in the field of theoretical ethics. The contributions to this volume have been selected in such a way that all of the fundamental questions concerning the nature of intrinsic value are treated in depth and from a variety of viewpoints. These questions include how to understand the concept of intrinsic value, what sorts of things can have intrinsic value, and how to compute intrinsic value. The editors have added an introduction that ties these questions together and places the contributions in context, and they have also provided an extensive bibliography. The result is a comprehensive, balanced, and detailed picture of current thinking about intrinsic value, one that provides an indispensable backdrop against which future writings on the topic may be assessed.

This interdisciplinary and accessible book will help environmentalists to make stronger arguments in favor of conserving biodiversity.
