David Schmidtz

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.

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.

This essay considers whether acts of altruism can be rational. Rational choice, according to the standard instrumentalist model, consists of maximizing one's utility, or more precisely, maximizing one's utility subject to a budget constraint. We seek the point of highest utility lying within our limited means. The term ‘utility’ could mean a number of different things, but in recent times utility has usually been interpreted as preference satisfaction . To have a preference is to care , to want one alternative more than another

Christopher Morris’s book is a product of years of reflection, scholarship, and worldly experience. I have read books that were too long in the making, such that the young author who began and the older author who finished did not even use basic terms in the same way. In Morris’s case, however, the years of reflection were altogether salutary. Morris’s book started out clever and ended up wise. Any reader interested in political philosophy is bound to find it richly rewarding. Morris makes bold claims, but his arguments are unfailingly moderate, measured, and circumspect. This review largely will let Morris speak for himself

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.

This essay compares Rawls's and Nozick's theories of justice. Nozick thinks patterned principles of justice are false, and offers a historical alternative. Along the way, Nozick accepts Rawls's claim that the natural distribution of talent is morally arbitrary, but denies that there is any short step from this premise to any conclusion that the natural distribution is unjust. Nozick also agrees with Rawls on the core idea of natural rights liberalism: namely, that we are separate persons. However, Rawls and Nozick interpret that idea in different ways-momentously different ways. The tension between their interpretations is among the forces shaping political philosophy to this day.

We have taken the “why be moral?” question so seriously for so long. It suggests that we lack faith in the rationality of morality. The relative infrequency with which we ask “why be prudent?” suggests that we have no corresponding lack of faith in the rationality of prudence. Indeed, we have so much faith in the rationality of prudence that to question it by asking “why be prudent?” sounds like a joke. Nevertheless, our reasons and motives to be prudent are every bit as contingent as our reasons and motives to be moral–or so I argue in Sections II and III.A second theme of this essay is thatconflictbetween morality and self-interest is contingent as well. The moral perspective, as characterized in Section IV, does not require a universal regard for others, whereas the kind of self-interested perspective characterized in Section III does not require a wholesale disregard for others. Both perspectives make room for a deep although not universal other-regard–or so I argue in Section V.

According to conservationism, scarce and precious resources should be conserved and used wisely. According to preservation ethics, we should not think of wilderness as merely a resource. Wilderness commands reverence in a way mere resources do not. Each philosophy, I argue, can fail by its own lights, because trying to put the principles of conservationism or preservationism into institutional practice can have results that are the opposite of what the respective philosophies tell us we ought to be trying to achieve. For example, if the wisest use of South American rainforests is no use at all, then in that case conservationism by its own lights defers to preservationism. Analogously, if, when deprived of the option of preserving elephants as a resource, Africans respond by not preserving elephants at all, then in that case preservationism by its own lights defers to conservationism
