In this paper I tell the story of the evolution of the climate change regime, locating its origins in "the dream of Rio," which supposed that the nations of the world would join in addressing the interlocking crises of environment and development. I describe the failure at Copenhagen and then go on to discuss the "reboot" of the climate negotiations advocated by Eric A. Posner and David Weisbach. I bring out some ambiguities in their notion of International Paretianism, which is supposed to effectively limit the influence of moral ideals in international affairs, and pose a dilemma. I go on to discuss the foundations of their views regarding climate justice, arguing that the most reasonable understandings of their favored theoretical views would not lead to some of their conclusions. Finally, I return to the climate regime, and make some observations about the road ahead, concluding that for the foreseeable future the most important climate change action will be within countries rather than among them.

Consequentialism is the family of theories that holds that acts are morally right, wrong, or indifferent in virtue of their consequences. Less formally and more intuitively, right acts are those that produce good consequences. A consequentialist theory includes at least the following three elements: an account of the properties or states in virtue of which consequences make actions right, wrong, or indifferent; a deontic principle which specifies how or to what extent the properties or states must obtain in order for an action to be right, wrong, or indifferent; and finally, a specification of what is in the domain of the deontic principle. For example, mental state and desire theories provide different accounts of the first element; maximizing and satisficing are distinct deontic principles; and Act and Rule Consequentialism specify different domains over which a deontic principle ranges. A wide range of alternative theories can be generated by modifying these three elements. For example, Hedonistic Act Utilitarianism which requires that each act maximize pleasure, and Perfectionist Lifetime Minimalism which requires that each life satisfy some minimal standard of perfection are both varieties of Consequentialsm. The conceptual space Consequentialism describes is vast, versions of Consequentialism vary radically in their plausibility, and few objections count against all versions of Consequentialism

Philosophers, like generals, tend to fight the last war. While activists and policy-makers are in the trenches fighting the problems of today, intellectuals are typically studying the problems of yesterday. There are some good reasons for this. It is more difficult to assess and interpret present events than those which are behind us. Time is needed for reflection and to gather reliable information about what has occurred. The desire to understand leads to a style of life that is primarily contemplative and retrospective

The contrast typically made between utilitarianism and virtue theory is overdrawn. Utilitarianism is a universal emulator: it implies that we should lie, cheat, steal, even appropriate Aristotle, when that is what brings about the best outcomes. In some cases and in some worlds it is best for us to focus as precisely as possible on individual acts. In other cases and worlds it is best for us to be concerned with character traits. Global environmental change leads to concerns about character because the best results will be produced by generally uncoupling my behavior from that of others. Thus, in this case and in this world, utilitarians should be virtue theorists

What is the environment, and how does it figure in an ethical life? This book is an introduction to the philosophical issues involved in this important question, focussing primarily on ethics but also encompassing questions in aesthetics and political philosophy. Topics discussed include the environment as an ethical question, human morality, meta-ethics, normative ethics, humans and other animals, the value of nature, and nature's future. The discussion is accessible and richly illustrated with examples. The book will be valuable for students taking courses in environmental philosophy, and also for a wider audience in courses in ethics, practical ethics, and environmental studies. It will also appeal to general readers who want a reliable and sophisticated introduction to the field.

This chapter sketches a broad history of practical ethics. It identifies five distinguishable styles of work in practical ethics: the Vertical Approach, the Horizontal Approach, Analysis and Intuition, Reasoning From Middle-Level Principles, and the Case Approach. It is argued that practical ethics is today a glorious mess, as evidenced by the different philosophical views implied by the different approaches. Some philosophers also practice more than one of these styles, sometimes in the same paper, which helps to explain the tension between practical ethics and the discipline of philosophy. If people working in this field cannot agree about what they are doing, then it is difficult to locate this field on a map of the discipline.

In recent years both philosophers and scientists have been sceptical about the existence of animal minds. This is in distinction to Hume who claimed that '...no truth appears to me more evident, than that beasts are endow'd with thought and reason as well as men'. I argue that Hume is correct about the epistemological salience of our ordinary practices of ascribing mental states to animals. The reluctance of contemporary philosophers and scientists to embrace the view that animals have minds is primarily a fact about their philosophy and science rather than a fact about animals. The recognition of this fact is the beginning of any serious effort to develop a science of cognitive ethology
