This essay seeks to understand the complex response to the current Black Lives Matter protests against police violence, which pose deeper questions about the forms of politics that black citizens—who are experiencing a defining moment of racial terror in the United States in the twenty-first century—can and should pursue. When other citizens and state institutions betray a lack of care and concern for black suffering, which in turn makes it impossible for those wrongs to be redressed, is it fair to (...) ask blacks to enact “appropriate” democratic politics? These questions are explored via a reading of Danielle Allen and Ralph Ellison’s meditations on the problem of democratic loss and Hannah Arendt’s critique of school desegregation battles in the 1960s. I suggest that there is a conceptual trap in romantic historical narratives of black activism (especially the civil rights movement) that recast peaceful acquiescence to loss as a form of democratic exemplarity.

Several popular arguments against teaching business ethics are examined: (a) the ethical duty of business people is to maximize profit within the law, whence the irrelevance of ethics courses (the Milton Friedman argument); (b) business people respond to economic and legal incentives, not to ethical sentiments, which means that teaching ethics will have no effect; (c) one cannot study ethics in any meaningful sense anyway, because it is a matter of personal preference and is unsusceptible to rational treatment; (d) moral (...) character is formed in early childhood, not while sitting in ethics class; and (e) business students see no motivation to study ethics and will not take it seriously. The mistakes and confusion that underlie these arguments are exposed. (shrink)

Solidarity-the reciprocal relations of trust and obligation between citizens that are essential for a thriving polity-is a basic goal of all political communities. Yet it is extremely difficult to achieve, especially in multiracial societies. In an era of increasing global migration and democratization, that issue is more pressing than perhaps ever before. In the past few decades, racial diversity and the problems of justice that often accompany it have risen dramatically throughout the world. It features prominently nearly everywhere: from the (...) United States, where it has been a perennial social and political problem, to Europe, which has experienced an unprecedented influx of Muslim and African immigrants, to Latin America, where the rise of vocal black and indigenous movements has brought the question to the fore. Political theorists have long wrestled with the topic of political solidarity, but they have not had much to say about the impact of race on such solidarity, except to claim that what is necessary is to move beyond race. The prevailing approach has been: How can a multicultural and multiracial polity, with all of the different allegiances inherent in it, be transformed into a unified, liberal one? Juliet Hooker flips this question around. In multiracial and multicultural societies, she argues, the practice of political solidarity has been indelibly shaped by the social fact of race. The starting point should thus be the existence of racialized solidarity itself: How can we create political solidarity when racial and cultural diversity are more or less permanent? Unlike the tendency to claim that the best way to deal with the problem of racism is to abandon the concept of race altogether, Hooker stresses the importance of coming to terms with racial injustice, and explores the role that it plays in both the United States and Latin America. Coming to terms with the lasting power of racial identity, she contends, is the starting point for any political project attempting to achieve solidarity. (shrink)

The late Colin Macleod's commentary on Iliad 24 has rightly received praise for its sensitivity to the nuances of Homeric language and its appreciation of the entire poem as a carefully constructed work of art. Although reluctant to accept the more radical solutions proposed by the ‘oral’ school, Macleod showed himself fully aware of the contribution made by the oral theory towards elucidating the history of the epic. Nevertheless, his commentary is concerned principally with the Iliad as we have it: (...) a poem which is at one level a masterly re-telling of saga but at another a sublime tragedy, commiserating the sorrows inseparable from human existence and holding up for our admiration the heroes who nobly confront pain and death. I believe that much, and probably most, of the Iliad can and should be viewed in this light. The last book of all, as Macleod himself has shown, offers especially rich rewards to an interpreter who keeps in the front of his mind the overriding aims of the great poet. Yet Macleod's method, like any other single method, will never yield a fully satisfactory answer on all occasions. However the ‘definitive’ or ‘monumental’ composition of the Iliad was brought about, it formed only one stage in the development of the Greek epic. Our Iliad cannot have been the first or the only treatment, on a large scale, of the matter of Troy. (shrink)

Merging logic and mathematics in deductive inference-an innovative, cutting-edge approach. Optimization methods for logical inference? Absolutely, say Vijay Chandru and John Hooker, two major contributors to this rapidly expanding field. And even though "solving logical inference problems with optimization methods may seem a bit like eating sauerkraut with chopsticks... it is the mathematical structure of a problem that determines whether an optimization model can help solve it, not the context in which the problem occurs." Presenting powerful, proven optimization techniques for (...) logic inference problems, Chandru and Hooker show how optimization models can be used not only to solve problems in artificial intelligence and mathematical programming, but also have tremendous application in complex systems in general. They survey most of the recent research from the past decade in logic/optimization interfaces, incorporate some of their own results, and emphasize the types of logic most receptive to optimization methods-propositional logic, first order predicate logic, probabilistic and related logics, logics that combine evidence such as Dempster-Shafer theory, rule systems with confidence factors, and constraint logic programming systems. Requiring no background in logic and clearly explaining all topics from the ground up, Optimization Methods for Logical Inference is an invaluable guide for scientists and students in diverse fields, including operations research, computer science, artificial intelligence, decision support systems, and engineering.

This book develops an intellectual framework for analyzing ethical dilemmas that is both grounded in theory and versatile enough to deal rigorously with real-world issues. It sees ethics as a necessary foundation for the social infrastructure that makes modern life possible, much as engineering is a foundation for physical infrastructure. It is not wedded to any particular ethical philosophy but draws from several traditions to construct a unified and principled approach to ethical reasoning. Rather than follow the common academic practice (...) of seeking a reflective equilibrium of moral intuitions and principles, it builds on a few bedrock principles of rational thought that serve as criteria for valid argumentation. It develops the ideas from the ground up, without presupposing any background in ethics or philosophy. Epistemologically, the book views ethics as parallel to mathematics, in that it relies on generally accepted proof techniques to establish results. Whereas mathematics rests on such proof paradigms as mathematical induction and proof by contradiction, ethics can be seen as relying on proof by applying consistency tests, such as generalizability and respect for autonomy. Utilitarianism also plays a key role, but it is reconceived as a deontological criterion. This approach obviously requires that these criteria be formulated more rigorously than is normally the case. To accomplish this, the book begins with the classical idea that an action is distinguishable from mere behavior by virtue of its having a coherent rationale, where coherence requires passing certain consistency tests such as generalizability. An action is therefore inseparable from its rationale, and generalizability is defined in terms of consistency with the rationale. A utilitarian criterion receives a similar treatment with respect to a means-end rationale. Respect for autonomy is grounded in a carefully developed action theory that takes into account such concepts as joint autonomy, implied consent, and the permissibility of interference with unethical behavior. It provides an account of responsibility that is both practical and theoretically satisfying, and it yields a novel solution of the much-discussed trolley car dilemmas. The book is written for a general audience and strives to be as readable and engaging as possible, while maintaining rigor. It begins by dispelling a raft of misconceptions that trivialize ethics and block its development as an essential tool of modern life, such as the notion that ethics is just a matter of opinion without rational foundation. After presenting the ethical principles just described, along with many examples, it provides several chapters that analyze real-life dilemmas, many obtained from the author's students and professional workshop participants. One cannot understand physics or chemistry without seeing how their principles are applied to real problems, and the same is true of ethics. These chapters demonstrate that a unified normative theory can deal with a wide range of real cases while achieving a reasonable level of objectivity and rigor. (shrink)
