Recently, there has been a resurgence of interest in general, comprehensive models of human cognition. Such models aim to explain higher-order cognitive faculties, such as deliberation and planning. Given a computational representation, the validity of these models can be tested in computer simulations such as software agents or embodied robots. The push to implement computational models of this kind has created the field of artificial general intelligence (AGI). Moral decision making is arguably one of the most challenging tasks for computational (...) approaches to higher-order cognition. The need for increasingly autonomous artificial agents to factor moral considerations into their choices and actions has given rise to another new field of inquiry variously known as Machine Morality, Machine Ethics, Roboethics, or Friendly AI. In this study, we discuss how LIDA, an AGI model of human cognition, can be adapted to model both affective and rational features of moral decision making. Using the LIDA model, we will demonstrate how moral decisions can be made in many domains using the same mechanisms that enable general decision making. Comprehensive models of human cognition typically aim for compatibility with recent research in the cognitive and neural sciences. Global workspace theory, proposed by the neuropsychologist Bernard Baars (1988), is a highly regarded model of human cognition that is currently being computationally instantiated in several software implementations. LIDA (Franklin, Baars, Ramamurthy, & Ventura, 2005) is one such computational implementation. LIDA is both a set of computational tools and an underlying model of human cognition, which provides mechanisms that are capable of explaining how an agent’s selection of its next action arises from bottom-up collection of sensory data and top-down processes for making sense of its current situation. We will describe how the LIDA model helps integrate emotions into the human decision-making process, and we will elucidate a process whereby an agent can work through an ethical problem to reach a solution that takes account of ethically relevant factors.

Building artificial moral agents (AMAs) underscores the fragmentary character of presently available models of human ethical behavior. It is a distinctly different enterprise from either the attempt by moral philosophers to illuminate the “ought” of ethics or the research by cognitive scientists directed at revealing the mechanisms that influence moral psychology, and yet it draws on both. Philosophers and cognitive scientists have tended to stress the importance of particular cognitive mechanisms, e.g., reasoning, moral sentiments, heuristics, intuitions, or a moral grammar, (...) in the making of moral decisions. However, assembling a system from the bottom-up which is capable of accommodating moral considerations draws attention to the importance of a much wider array of mechanisms in honing moral intelligence. Moral machines need not emulate human cognitive faculties in order to function satisfactorily in responding to morally significant situations. But working through methods for building AMAs will have a profound effect in deepening an appreciation for the many mechanisms that contribute to a moral acumen, and the manner in which these mechanisms work together. Building AMAs highlights the need for a comprehensive model of how humans arrive at satisfactory moral judgments. (shrink)
We present a theoretical account of implicit and explicit learning in terms of ACT-R, an integrated architecture of human cognition as a computational supplement to Dienes & Perner's conceptual analysis of knowledge. Explicit learning is explained in ACT-R by the acquisition of new symbolic knowledge, whereas implicit learning amounts to statistically adjusting subsymbolic quantities associated with that knowledge. We discuss the common foundation of a set of models that are able to explain data gathered in several signature paradigms of implicit (...) learning. (shrink)
A principal goal of the discipline of artificial morality is to design artificial agents to act as if they are moral agents. Intermediate goals of artificial morality are directed at building into AI systems sensitivity to the values, ethics, and legality of activities. The development of an effective foundation for the field of artificial morality involves exploring the technological and philosophical issues involved in making computers into explicit moral reasoners. The goal of this paper is to discuss strategies for implementing (...) artificial morality and the differing criteria for success that are appropriate to different strategies. (shrink)
The implementation of moral decision making abilities in artificial intelligence (AI) is a natural and necessary extension to the social mechanisms of autonomous software agents and robots. Engineers exploring design strategies for systems sensitive to moral considerations in their choices and actions will need to determine what role ethical theory should play in defining control architectures for such systems. The architectures for morally intelligent agents fall within two broad approaches: the top-down imposition of ethical theories, and the bottom-up building of (...) systems that aim at goals or standards which may or may not be specified in explicitly theoretical terms. In this paper we wish to provide some direction for continued research by outlining the value and limitations inherent in each of these approaches. (shrink)
"An invaluable guide to avoiding the stuff of science-fiction nightmares."--John Gilby, Times Higher Education -/- "Moral Machines is a fine introduction to the emerging field of robot ethics. There is much here that will interest ethicists, philosophers, cognitive scientists, and roboticists."-Peter Danielson, Notre Dame Philosophical Reviews -/- "Written with an abundance of examples and lessons learned, scenarios of incidents that may happen, and elaborate discussions on existing artificial agents on the cutting edge of research/practice, Moral Machines goes beyond what is (...) known as computer ethics into what will soon be called the discipline of machine morality. Highly recommended."-G. Trajkovski, CHOICE -/- "...the book does succeed in making the essential point that the phrase 'moral machine' is not an oxymoron. It also provides a window onto an area of research with which psychologists are unlikely to be familiar and one from which, at some point, we may be able to learn quite a lot."-PsycCRITIQUES -/- "Moral Machines represents a valuable addition to, and extension of, the current literature on machine morality. As the development of autonomous artificial moral agents becomes closer to being realized, I suspect that this book will only gain in importance."--Metapsychology. (shrink)
PC Wars: Politics and Theory in the Academy addresses the very issue of political correctness and the current skirmishes in the culture wars. It includes statements from many of our leading contemporary public intellectuals, including Joan Wallach Scott, Michael Be;rube;, Bruce Robbins, Henry Giroux, and Gerald Graff. The collection marks a watershed in the debate about "pc" in that it presents serious considerations and analyses of the factors, causes, and consequences of the culture wars. Carefully examining the construction (...) of "pc," PC Wars analyses political correctness by focusing on the mass media, class politics, and the ideology of managerial democracy. It places the disputes around "pc" in the context of contemporary developments in critical and cultural theory and the current backlash against theory, manifested in the recent attacks on Marxism, feminism and deconstruction. The book also scrutinizes the undercurrents of anti-intellectualism and anti-professionalism which have tended to create a fertile ground for the "pc" hysteria. Offering much more than slogans and slinging arrows, PC Wars provides a spirited and critical look at the reaction, ideology, and political forces that have coalesced around the term. Contributors: Michael Be;rube;, Reed Way Dasenbrock, Frank Farmer, Henry Giroux, Gerald Graff, Darlene Hantzis and Devoney Looser, John S. Howard and James M. Lang, Tom Lewis, James Neilson, Christopher Newfield, Richard Ohmann, Burce Robbins, Barry Sarchett, Joan W. Scott, Michael Sprinker, Jeffrey Williams. (shrink)
This paper traces the history of uses of the word "gender". It suggests that though "gender" has been recuperated and become commonplace, many issues persist around the way "women" and "men", and the power relations between them, are defined and are evolving. Provided it still allows us to question the meanings attached to the sexes, how they are established and in what contexts, gender remains a useful, because critical, analytical category.
Wendell Wallach and Colin Allen’s Moral Machines: Teaching Robots Right From Wrong (Oxford University Press, 2009) explores efforts to develop machines that, not only can be employed for good or bad ends, but which themselves can be held morally accountable for what they do— artificial moral agents (AMAs). This essay is a critical response to Wallach and Allen’s conjectures. Although Wallach and Allen do not suggest that we are close to being able to create full-fledged AMAs, they (...) do talk seriously about making incremental progress in the direction of creating them (even if we never fully succeed). However, there are important questions about the moral development of AMAs that Moral Machines does not address. Given the responsibilities entrusted to human moral agents, we take questions about their moral development very seriously. In the case of children, the hope is that eventually they will develop into full-fledged moral agents. How might we expect this to go with less than fully formed AMAs? Will there be a comparable story of moral development and moral education that we can tell? (shrink)
In his famous 1950 paper where he presents what became the benchmark for success in artificial intelligence, Turing notes that "at the end of the century the use of words and general educated opinion will have altered so much that one will be able to speak of machines thinking without expecting to be contradicted" (Turing 1950, 442). Kurzweil (1990) suggests that Turing's prediction was correct, even if no machine has yet to pass the Turing Test. In the wake of the (...) computer revolution, research in artificial intelligence and cognitive science has pushed in the direction of interpreting "thinking" as some sort of computational process. On this understanding, thinking is something computers (in principle) and humans (in practice) can both do. It is difficult to say precisely when in history the meaning of the term "thinking" headed in this direction. Signs are already present in the mechanistic and mathematical tendencies of the early Modern period, and maybe even glimmers are apparent in the ancient Greeks themselves. But over the long haul, we somehow now consider "thinking" as separate from the categories of "thoughtfulness" (in the general sense of wondering about things), "insight" and "wisdom." Intelligent machines are all around us, and the world is populated with smart cars, smart phones and even smart (robotic) appliances. But, though my cell phone might be smart, I do not take that to mean that it is thoughtful, insightful or wise. So, what has become of these latter categories? They seem to be bygones left behind by scientific and computational conceptions of thinking and knowledge that no longer have much use for them. In 2000, Allen, Varner and Zinser addressed the possibility of a Moral Turing Test (MTT) to judge the success of an automated moral agent (AMA), a theme that is repeated in Wallach and Allen (2009)..

Time travelers and battles between people and machines provoke old philosophical questions: Can the past really be changed? How do we differentiate ourselves from machines? Can machines have an inner life? Brown (philosophy & critical thinking, LaGuardia Community Coll.) and Decker (philosophy, Eastern Washington Univ.; coeditor, Star Wars and Philosophy ) collect 19 essays by primarily young academics who pursue these questions with entertaining verve and philosophical skill. The Terminator story is about something well intentioned—a defense project—going wrong, but none (...) of the essays here presses this issue to a clear conclusion (readers whose interest is aroused would do well to read Wendell Wallach and Colin Allen's Moral Machines , concerned with actual machines and ones that might soon exist). Among the book's bright spots are contributions from Harry Chotiner and Jennifer Culver that show us something about how the movies work and explore the feminist issues posed by placing Sarah Connor at the center of the story. One essayist, Phillip Seng, addresses the philosophical trouble at the heart of the tale: telling good from evil in politics is hard. This book will earn a place in libraries by presenting serious issues in a way that attracts readers.—Leslie Armour, Dominican Univ. Coll., Ottawa, Ont. (shrink)
The emerging discipline of Machine Ethics is concerned with creating autonomous artificial moral agents that perform ethically significant actions out in the world. Recently, Wallach and Allen (Moral machines: teaching robots right from wrong, Oxford University Press, Oxford, 2009) and others have argued that a virtue-based moral framework is a promising tool for meeting this end. However, even if we could program autonomous machines to follow a virtue-based moral framework, there are certain pressing ethical issues that need to be (...) taken into account, prior to the implementation and development stages. Here I examine whether the creation of virtuous autonomous machines is morally permitted by the central tenets of virtue ethics. It is argued that the creation of such machines violates certain tenets of virtue ethics, and hence that the creation and use of those machines is impermissible. One upshot of this is that, although virtue ethics may have a role to play in certain near-term Machine Ethics projects (e.g. designing systems that are sensitive to ethical considerations), machine ethicists need to look elsewhere for a moral framework to implement into their autonomous artificial moral agents, Wallach and Allen’s claims notwithstanding.

On March 15, 2006, French President Jacques Chirac signed into law an amendment to his country's education statute, banning the wearing of conspicuous signs of religious affiliation in public schools. Prohibited items included a large cross, a veil, or skullcap. The ban was expressly introduced by lawmakers as an application of the principle of government neutrality, du principe de laïcité. Opponents of the law viewed it primarily as an intolerant assault against the hijab, a head and neck wrap worn by (...) many Muslim women around the world. In Politics of the Veil, Professor Joan Wallach Scott offers an illuminating account of the significance of the hijab in France. Scott's lucid, compact examination of the hijab complements previous feminist scholarship on veiling with a close look at its role in a particular time and place - contemporary France - where it has been the subject matter of a unique political discourse. How different is America's political discourse surrounding religious symbols in the schools as compared to the French? I offer a U.S. constitutional perspective on the rights of religious minorities and women in the public schools, and suggest that a ban on the hijab must be considered unconstitutional. A proposal for a national rule against the hijab in public schools or universities would fall flat in the United States. When compared to U.S. approaches to the hijab, the French experience examined by Joan Wallach Scott underscores an important point: there is more than one way to be a modern, multicultural western liberal democracy with a Muslim population, and some ways are better than others.
