David Schmidtz

The Macmillan Interdisciplinary Handbooks: Philosophy series serves undergraduate college students who have had little or no exposure to philosophy, as well as the curious lay reader. Following this first primer volume, which introduces both the discipline and the topics of the remaining nine volumes, each handbook will usher the reader into a subfield of philosophy, and explore fifteen to thirty topics in that subfield. Every chapter in each volume will use vehicles such as film to facilitate understanding of philosophical issues; for example, the film Dead Man Walking may be used as an introduction to issues related to the death penalty.

Is it rational to be moral? How do rationality and morality fit together with being human? These questions are at the heart of David Schmidtz's exploration of the connections between rationality and morality. This inquiry leads into both metaethics and rational choice theory, as Schmidtz develops conceptions of what it is to be moral and what it is to be rational. He defends a fairly expansive conception of rational choice, considering how ends as well as means can be rationally chosen and explaining the role of self-imposed constraints in a rational life plan. His moral theory is dualistic, ranging over social structure as well as personal conduct and building both individual and collective rationality into its rules of recognition for morals. To the "why be moral" question, Schmidtz responds that being moral is rational, but he does not assume we have reasons to be rational. Instead, Schmidtz argues that being moral is rational in a particular way and that beings like us in situations like ours have reasons to be rational in just that way. This approach allows him to identify decisive reasons to be moral; at the same time, it explains why immorality is as prevalent as it is. This book thus offers a set of interesting and realistic conclusions about how morality fits into the lives of humanly rational agents operating in an institutional context like our own.

Libertarians often bill their theory as an alternative to both the traditional Left and Right. _The Routledge Handbook of Libertarianism_ helps readers fully examine this alternative, without preaching it to them, exploring the contours of libertarian thinking on justice, institutions, interpersonal ethics, government, and political economy. The 31 chapters--all written specifically for this volume--are organized into five parts. Part I asks, what should libertarianism learn from other theories of justice, and what should defenders of other theories of justice learn from libertarianism? Part II asks, what are some of the deepest problems facing libertarian theories? Part III asks, what is the right way to think about property rights and the market? Part IV asks, how should we think about the state? Finally, part V asks, how well can libertarianism deal with some of the major policy challenges of our day, such as immigration, trade, religion in politics, and paternalism in a free market. Among the _Handbook_’s chapters are those from critics who write about what they believe libertarians get right as well as others from leading libertarian theorists who identify what they think libertarians get wrong. As a whole, the _Handbook_ provides a comprehensive, clear-eyed look at what libertarianism has been and could be, and why it matters.

Significantly revised in this third edition, Environmental Ethics: What Really Matters, What Really Works examines morality from an environmental perspective. Featuring accessible selections—from classic articles to examples of cutting-edge original research—it addresses both theory and practice. Asking what really matters, the first section of the book explores the abstract ideas of human value and value in nature. The second section turns to the question of what really works—what it would take to solve our real-world environmental problems. Moving beyond the "hype," it presents authoritative essays on applying environmental ethics to the issues that matter right now. The selections present philosophical, biological, and socially scientific approaches to the major issues. Environmental Ethics also features first-hand descriptions from people who have actually been involved in wildlife and conservation initiatives.

What is justice? Questions of justice are questions about what people are due. However, what that means in practice depends on the context in which the question is raised. Depending on context, the formal question of what people are due is answered by principles of desert, reciprocity, equality, or need. Justice, therefore, is a constellation of elements that exhibit a degree of integration and unity. Nonetheless, the integrity of justice is limited, in a way that is akin to the integrity of a neighborhood rather than that of a building. A theory of justice offers individuals a map of that neighborhood, within which they can explore just what elements amount to justice.

It is widely held that the proper role of criminal punishment is to ensure in a cost-efficient manner that criminal laws will be obeyed. As James Buchanan puts it,the reason we have courts is not that we want people to be convicted of crimes but that we want people not to commit them. The whole procedure of the law is one, essentially, of threatening people with unpleasant consequences if they do things which are regarded as objectionable.According to the deterrence theory of punishment, which I will here accept without argument in order to tease out some of its implications, legislators must be aware of opportunities to maximize the threat value of criminal prohibitions. By maximizing deterrence, we minimize the cost of crime. On the other hand, creating these threats, and carrying them out, is also costly. So we also wish to minimize the cost of avoiding crime. An efficient deterrent, therefore, will be one which minimizes the sum of the costs of crime and crime avoidance, where ‘cost’ is to be broadly construed.

Samuel Scheffler says, “none of the most prominent contemporary versions of philosophical liberalism assigns a significant role to desert at the level of fundamental principle.” To the extent that this is true, the most prominent contemporary versions of philosophical liberalism are mistaken. In particular, there is an aspect of what we do to make ourselves deserving that, although it has not been discussed in the literature, plays a central role in everyday moral life, and for good reason. As with desert, reciprocity inspires skepticism. What Allen Buchanan calls justice as reciprocity implies that duties of justice obtain only among those who can do each other favors. So characterized, justice as reciprocity is at best only a part of justice – a part that is silent on duties between people who have no favors to offer each other. Still, the more modest root idea of reciprocity – the idea that returning favors is at very least a good thing – remains compelling. What can we say on behalf of this root idea? This article is part of a larger work on the elements of justice. Both parts of it begin with and build on James Rachels’ seminal paper “What People Deserve.”.

Species egalitarianism is the view that all species have equal moral standing. To have moral standing is, at a minimum, to command respect, to be something more than a mere thing. Is there any reason to believe that all species have moral standing in even this most minimal sense? If so — that is, if all species command respect — is there any reason to believe they all command equal respect. The article summarises critical responses to Paul Taylor’s argument for species egalitarianism, then explains why other species command our respect but also why they do not command equal respect. The intuition that we should have respect for nature is part of what motivates people to embrace species egalitarianism, but one need not be a species egalitarian to have respect for nature. The article closes by questioning whether species egalitarianism is even compatible with respect for nature.

Sometimes people act contrary to environmentalist values because they reject those values. This is one kind of conflict: conflict in values. There is another kind of conflict in which people act contrary to environmentalist values even though they embrace those values: because they cannot afford to act in accordance with them. Conflict in priorities occurs not because people’s values are in conflict, but rather because people’s immediate needs are in conflict. Conflict in priorities is not only an environmental conflict, but also often an economic conflict—a conflict rooted in differing economic circumstance. Such a conflict cannot be resolved as an environmental conflict unless it is also resolved as an economic one.
