Artificial Intelligence as a discipline has gotten bogged down in subproblems of intelligence. These subproblems are the result of applying reductionist methods to the goal of creating a complete artificial thinking mind. In Brooks (1987) 1 have argued that these methods will lead us to solving irrelevant problems; interesting as intellectual puzzles, but useless in the long run for creating an artificial being.
We have previously built a small IKg ([Angle 89] and [Brooks 89]) six legged walking robot named Genghis. It was remarkably successful as a testbed to develop walking and learning algorithms. It encouraged us to build a more fully engineered robot with higher performance. We are building two copies of the robot, both 1.6Kg in mass. Their generic name is Attila. Attila has 24 actuators and over 150 sensors, all connected via a local network (the I2C bus) to 11 (...) onboard computers. (shrink)
Once seen as synonymous with "anti-feminism" postfeminism is now understood as the theoretical meeting ground between feminism and anti-foundationalist movements such as postmodernism, post-structuralism and post-colonialsm. In this clear exposition of some of the major debates, theorists and practitioners, Ann Brooks shows how feminism is being redefined for the twenty first century. Individual chapters look at postfeminism in relation to feminist epistemology, Foucault, psychoanalytic theory and semiology, postmodernism and postcolonialism, cultural politics, popular culture, film and media, and sexuality and (...) identity. For all students looking for guidance through the sometimes murky waters of contemporary feminist theory, this book will provide a reassuring first port of call. (shrink)
In this article, I argue that - despite the absence of any clear influence of one theory on the other - the legal theories of Dworkin and Hegel share several similar and, at times, unique positions that join them together within a distinctive school of legal theory, sharing a middle position between natural law and legal positivism. In addition, each theory can help the other in addressing certain internal difficulties. By recognizing both Hegel and Dworkin as proponents of a position (...) lying in between natural law and legal positivist jurisprudence, we can gain clarity in why their general legal theories seem to fit uncomfortably, if indeed they can be said to fit at all, within so many different camps - while fitting comfortably in no particular camp - as well as highlight what has been overlooked.

This article argues that even if we grant that murderers may deserve death in principle, retributivists should still oppose capital punishment. The reason? Our inability to know with certainty whether or not individuals possess the necessary level of desert. In large part due to advances in science, we can only be sure that no matter how well the trial is administered or how many appeals are allowed or how many years we let elapse, we will continue to execute innocent persons (...) for as long as we legalize capital punishment. Thus, on grounds of desert, this article argues that retributivists should oppose capital punishment. (shrink)
Artificial intelligence research has foundered on the issue of representation. When intelligence is approached in an incremental manner, with strict reliance on interfacing to the real world through perception and action, reliance on representation disappears. In this paper we outline our approach to incrementally building complete intelligent Creatures. The fundamental decomposition of the intelligent system is not into independent information processing units which must interface with each other via representations. Instead, the intelligent system is decomposed into independent and parallel activity (...) producers which all interface directly to the world through perception and action, rather than interface to each other particularly much. The notions of central and peripheral systems evaporateeverything is both central and peripheral. Based on these principles we have built a very successful series of mobile robots which operate without supervision as Creatures in standard office environments. (shrink)
Polygamy is a hotly contested practice and open to widespread misunderstandings. This practice is defined as a relationship between either one husband and multiple wives or one wife and multiple husbands. Today, 'polygamy' almost exclusively takes the form of one husband with multiple wives. In this article, my focus will centre on limited defences of polygamy offered recently by Chesire Calhoun and Martha Nussbaum. I will argue that these defences are unconvincing. The problem with polygamy is primarily that it is (...) a structurally inegalitarian practice in both theory and fact. Polygamy should be opposed for this reason. (shrink)
It is widely accepted by the scientific community and beyond that human beings are primarily responsible for climate change and that climate change has brought with it a number of real problems. These problems include, but are not limited to, greater threats to coastal communities, greater risk of famine, and greater risk that tropical diseases may spread to new territory. In keeping with J. S. Mill's 'Harm Principle', green political theorists often respond that if we are contributing a harm to (...) others in contributing to climate change and its negative effects, we then have a negative duty to assist those we have harmed and to reduce our carbon emissions. In this paper, I will take seriously negative duties stemming from a contribution to climate change and demonstrate that our negative duties do not demand that we necessarily end our contribution to climate change if we were able to compensate those who may be affected by climate change. Thus, the conclusion of many green political theorists - that we must reduce our carbon emissions - does not necessarily follow from the view that humans are primarily responsible for climate change and its attended ill effects.

The problem of global poverty has reached terrifying proportions. Since the end of the Cold War, ordinary deaths from starvation and preventable diseases amount to approximately 250 million people, most of them children. Thomas Pogge argues that wealthy states have a responsibility to help those in severe poverty. This responsibility arises from the foreseeable and avoidable harm the current global institutional order has perpetrated on poor states. Pogge demands that wealthy states eradicate global poverty not merely because they have the (...) resources, but because they share responsibility for its continuation. For Pogge, global poverty is more than a wrong imposed on the poor: it is a violation of human rights and a crime. In this paper, I critically examine Pogge's claim that global poverty is a crime. My aim is to demonstrate that Pogge's conclusions do not follow from his arguments. That is, if affluent states have a negative duty to assist those in severe poverty, their duty is not absolute because they are not fully responsible for this poverty. Moreover, if global poverty is one of the greatest crimes against humanity, then it seems inappropriate at best to champion proposals, pace Pogge, that lets the guilty parties walk free. (shrink)
The most widespread interpretation amongst contemporary theorists of Kant's theory of punishment is that it is retributivist. On the contrary, I will argue there are very different senses in which Kant discusses punishment. He endorses retribution for moral law transgressions and consequentialist considerations for positive law violations. When these standpoints are taken into consideration, Kant's theory of punishment is more coherent and unified than previously thought. This reading uncovers a new problem in Kant's theory of punishment. By assuming a potential (...) offender's intentional disposition as Kant does without knowing it for certain, we further exacerbate the opportunity for misdiagnosis. (shrink)
In a recent article, Thomas Christiano defends the intrinsic justice of democracy grounded in the principle of equal consideration of interests. Each citizen is entitled to a single vote, equal in weight to all other citizens. The problem with this picture is that all citizens must meet a threshold of minimal competence. My argument is that Christiano is wrong to claim a minimum threshold of competency is fully consistent with the principle of equality. While standards of minimal competency may be (...) justifiable, these standards justify political inequality. This paper explores the relationship between equality and democracy in terms of minimal competency, demonstrating how minimal competency is justified and why it is inegalitarian in interesting ways.

Nearly every major philosophy, from Plato to Hegel and beyond, has argued that democracy is an inferior form of government, at best. Yet, virtually every contemporary political philosophy working today - whether in an analytic or postmodern tradition - endorses democracy in one variety or another. Should we conclude then that the traditional canon is meaningless for helping us theorize about a just state? In this paper, I will take up the criticisms and positive proposals of two such canonical figures (...) in political philosophy: Plato and Hegel. At first glance, each is rather disdainful, if not outright hostile, to democracy. This is also how both have been represented traditionally. However, if we look behind the reasons for their rejection of (Athenian) democracy and the reasons behind their alternatives to democracy, I believe we can uncover a new theory of government that does two things. First, it maps onto the so-called Schumpeterian tradition of elite theories of democracy quite well. Second, perhaps surprisingly, it actually provides an improved justification for democratic government as we practice it today than rival theories of democracy. Thus, not only are Plato and Hegel not enemies of modern democratic thought after all, but each is actually quite useful for helping us develop democratic theory in a positive, not negative, manner.

This paper offers two potential worries in Robert B. Talisse's A Pragmatist Philosophy of Democracy. The first worry is that is that the picture of democracy on offer is incomplete. While Talisse correctly argues that democracy is about more than elections, democracy is also about more than deliberation between citizens. Talisse's deliberative democracy is problematic to the degree its view of deliberation fails to account for democracy. The second worry we may have concerns the relationship between Talisse's Peircean pragmatism and (...) deliberative democracy. If this pragmatism is always open to revision and change in light of future evidence, then no pragmatist should adhere to only one particular political system, such as democracy. When we claim that only one system can ever be justified, then we fail to honour our professed openness to revision and change in the future. If my analysis is correct, then I do not aim to demonstrate that Talisse's Peircean pragmatism is incorrect, only incomplete. Thus, the hope of this paper is to help develop this pragmatism further.

When can ever be justified in banning a religious practice? This paper focusses on Martha Nussbaum's capabilities approach. Certain religious practices create a clash between capabilities where the capability to religious belief and expression is in conflict with the capability of equal status and nondiscrimination. One example of such a clash is the case of polygamy. Nussbaum argues that there may be circumstances where polygamy may be acceptable. On the contrary, I argue that the capabilities approach cannot justify polygamy in (...) any circumstance. Her approach rules out polygamy, but may not rule out all non-monogamous relationships, such as polyamory. Finally, I conclude that the capabilities approach would benefit from a more robust understanding of recognition. (shrink)
The first part of this paper explores the general issues in using Artificial Life techniques to program actual mobile robots. In particular it explores the difficulties inherent in transferring programs evolved in a simulated environment to run on an actual robot. It examines the dual evolution of organism morphology and nervous systems in biology. It proposes techniques to capture some of the search space pruning that dual evolution offers in the domain of robot programming. It explores the relationship between robot (...) morphology and program structure, and techniques for capturing regularities across this mapping. (shrink)
Hegel's legacy is particularly controversial, not least in legal theory. He has been classified as a proponent of either natural law, legal positivism, the historical school, pre-Marxism, postmodern critical theory, and even transcendental legal theory. To what degree has Hegel actually influenced contemporary legal theorists? This review article looks at Michael Salter's collection Hegel and Law. I look at articles on civil disobedience, contract law, feminism, and punishment. I conclude noting similarities between Hegel's legal theory and that of Ronald Dworkin. (...) I also criticize the volume's emphasis on Hegel's postmodern credentials, all of which I doubt. (shrink)
Academic publishing is a world filled with more mystery than revelation. Often the best advice is made available only to those lucky enough to hear it by word of mouth. This is no less true with editing academic journals. I have enjoyed the honour of launching the Journal of Moral Philosophy and serving as its editor for the last ten years. I actively sought out the best advice on a number of issues from editors serving on leading journals as well (...) as their publishers. Despite the fact that most of the conversations focused on journals in the areas of law, philosophy, and political science, I believe that much of the general advice remains true for most disciplines. This editorial brings together some lessons learned over the years and reveals some secrets about the trade. My purpose is to improve the information available to share best practice and offer some insight into the minds of academic journal editors. This is a task I have performed previously on the topics of publishing advice and referee guidelines that I extend now to journal editing. I begin with a brief note about my background experiences before moving to advice on how to successfully propose a new journal to a publisher. I then discuss topics such as managing a journal launch before considering advice on the effective management of submissions received and further advice on journal development. (shrink)
In both Great Britain and the United States there has been a growing debate about the modern acceptability of jury nullification. Properly understood, juries do not have any constitutional right to ignore the law, but they do have the power to do so nevertheless. Juries that nullify may be motivated by a variety of concerns: too harsh sentences, improper government action, racism, etc. In this article, I shall attempt to defend jury nullification on a number of grounds. First, I discuss (...) the use of general verdicts and reject their replacement in criminal trials by special verdicts. Second, I examine verdicts based upon mistakes and racial prejudice, turning my attention to perverse verdicts and the question of whether or not juries are guilty of legislating when nullifying the law. Finally, I look at the problem of the awarding of excessive damages by juries. My goal will be to provide a sound theoretical defence of the practice of jury nullification. (shrink)
The purpose of this essay is to critically appraise J. Angelo Corlett's recent interpretation of Kant's theory of punishment as well as his rejection of Hegel's penology. In taking Kant to be a retributivist at a primary level and a proponent of deterrence at a secondary level, I believe Corlett has inappropriately wed together Kant's distinction between moral and positive law. Moreover, his support of Kant on these grounds is misguided as it is instead Hegel who holds such a distinction. (...) Finally, I attempt to refute the almost timeless retributivist rejection of deterrence-based theories of punishment on the grounds that the latter somehow would condone in some cases the punishment of innocent persons. These individuals almost always demand that no innocent person be punished as a rule of the highest order. (shrink)
In this journal, Michael Clark defends a "A Non-Retributive Kantian Approach to Punishment". I argue that both Kant's and Rawls's theories of punishment are retributivist to some extent. It may then be slightly misleading to say that by following the views of Kant and Rawls, in particular, as Clark does, we can develop a nonretributivist theory of punishment. This matter is further complicated by the fact Clark nowhere addresses Rawls's views on punishment: Rawls endorses a mixed theory combining retributive and (...) utilitarian features. Of those discussed by Clark, only Scanlon defends the use of nonretributivist punishments. Yet, here too Clark nowhere addresses Scanlon's views on punishment. Thus, Clark's views on retributive punishment are highly problematic. (shrink)
David Miller raises a number of interesting concerns with both weak and strong variants of cosmopolitanism. As an alternative, he defends a connection theory to address remedial responsibilities amongst states. This connection theory is problematic as it endorses a position where states that are causally and morally responsible for deprivation and suffering in other states may not be held remedially responsible for their actions. In addition, there is no international mechanism to ensure either that remedially responsible states offer assistance to (...) particular states nor some level of accountability for causally and/or morally responsible states. I suggest that an intermediary theory of cosmopolitanism offers one way of overcoming these difficulties. (shrink)

It is impossible to do good science without having an appreciation for the problems and concepts in the other levels of abstraction (at least in the direction from biology towards physics), but there are whole sets of tools, methods of analysis, theories and explanations within each discipline which do not cross those boundaries.
Plato justifies the concentration and exercise of power for persons endowed with expertise in political governance. This article argues that this justification takes two distinctly different sets of arguments. The first is what I shall call his 'ideal political philosophy' described primarily in the Republic as rule by philosopher-kings wielding absolute authority over their subjects. Their authority stems solely from their comprehension of justice, from which they make political judgements on behalf of their city-state. I call the second set of (...) arguments Plato's 'practical political philosophy' underlying his later thought, where absolute rule by philosopher-kings is undermined by the impure character of all political knowledge. Whereas the complete comprehension of justice sanctions the absolute political power of those with this expertise, partial knowledge of justice disallows for such a large investment of power. Plato's practical political philosophy argues for a mixed theory of governance fusing the institutions of monarchy with democracy in the best practical city-state. Thus, Plato comes to realize the insurmountable difficulties of his ideal political thought, preferring a more practical political philosophy instead. (shrink)
This article offers a justification for the continued use of jury trials. I shall critically examine the ability of juries to render just verdicts, judicial impartiality, and judicial transparency. My contention is that the judicial system that best satisfies these values is most preferable. Of course, these three values are not the only factors relevant for consideration. Empirical evidence demonstrates that juries foster both democratic participation and public legitimation of legal decisions regarding the most serious cases. Nevertheless, juries are costly (...) and, therefore, economically less efficient than competing modes of trial. I do not argue that all human beings possess an inalienable legal right to be tried by a jury. However, it is my hope that this analysis will make clear what we might gain or lose when we propose jury reforms. (shrink)
abstract Shame punishments have become an increasingly popular alternative to traditional punishments, often taking the form of convicted criminals holding signs or sweeping streets with a toothbrush. In her Hiding from Humanity, Martha Nussbaum argues against the use of shame punishments because they contribute to an offender's loss of dignity. However, these concerns are shared already by the courts which also have concerns about the possibility that shaming might damage an offender's dignity. This situation has not led the courts to (...) reject all uses of shaming, but only to accept shaming within certain safeguards. Thus, despite Nussbaum's important reservations against shame punishments, it may still be possible for her to accept shaming within specific parameters such as those set out by the courts that protect the dignity of an offender. As a result, she need not be opposed to the use of legitimate shame punishment. (shrink)
Most animals have significant behavioral expertise built in without having to explicitly learn it all from scratch. This expertise is a product of evolution of the organism; it can be viewed as a very long term form of learning which provides a structured system within which individuals might learn more specialized skills or abilities. This paper suggests one possible mechanism for analagous robot evolution by describing a carefully designed series of networks, each one being a strict augmentation of the previous (...) one, which control a six legged walking machine capable of walking over rough terrain and following a person passively sensed in the infrared spectrum. As the completely decentralized networks are augmented. the robot’s performance and behavior repetoire demonstrably improve. The rationale for such demonstrations is that they may provide a hint as to the requirements for automatically building massive networks to carry out complex sensory-motor tasks. The experiments with an actual robot ensure that an essence of reality is maintained and that no critical disabling problems have been ignored. (shrink)
This Comment demonstrates that policy judgements are not masked by philosophical references, nor do philosophers play any crucial role in contentious judicial decisions. Neomi Rao’s study is flawed for many reasons: incomplete content analysis, poor assessment of data, and an inadequate definition of philosophy. She should be criticised for hypocritically praising Court philosopher references in some instances and not others, especially with regard to the Court’s early development. This Comment searched unsuccessfully for an instance where philosophers were cited just once (...) in controversial cases regarding racial integration, capital punishment’s abolition and re-legality, and the 2000 Presidential election. Philosophers are peculiarly absent from major controversial cases. Rao claims the Court’s majority decisions avoided the “Philosophers’ Brief” because the philosophers’ argument was grounded in theory, not substantive legal argument surrounding issues of judicial precedent. This Comment challenges Rao’s use of “philosophy” as something entirely abstract and steeped in metaphysics. Philosophy is presented as a large umbrella covering diverse sub-fields, two of which are philosophy of law and political philosophy. These sub-fields are of great use to law. Thus, the Court has not illegitimately used philosophers to support personal policy preferences. Nor is the use of philosophy incommensurable with judicial decision-making. (shrink)
I want to raise the question of why we should give the Preface this special treatment. What do we hope to learn from such an extended examination of the Preface that will help further the study of Hegel's work beyond its present state?

Many Christians are split on whether they believe we should endorse or oppose capital punishment. Each side claims Biblical support for their professed position. This essay cannot hope to bring this debate to a conclusion. However, it will try to offer a different perspective.

The proposed way forward is not to claim there is a contradiction, but to place greater emphasis on understanding these statements in their (...) particular contexts, specifically with reference to their relation to Jesus’ New Covenant. Such a perspective should lead us to oppose capital punishment. (shrink)
This comment argues for the importance of global institutions to regulate nuclear power. Nuclear power presents challenges across national borders irrespective of whether plants are maintained safely. There are international agreements in place on the disposal of nuclear waste, an issue of great concern in terms of environmental and health effects for any nuclear power policy. However, there remains a pressing need for an international agreement to ensure the safe maintenance of nuclear facilities. Safe nuclear power beyond waste disposal should (...) receive more attention. Nuclear power policy is often a matter of pure state interest with national governments alone responsible for regulating the safe maintenance of nuclear facilities. It ought not be left to national governments alone to regulate the safe administration of nuclear power given the many threats to environmental safety and public health. This comment argues that global institutions may best address this problem. The comment concludes with recommendations on how nuclear power policy might be regulated. (shrink)
Integrating concepts of maintenance and of origins is essential to explaining biological diversity. The unified theory of evolution attempts to find a common theme linking production rules inherent in biological systems, explaining the origin of biological order as a manifestation of the flow of energy and the flow of information on various spatial and temporal scales, with the recognition that natural selection is an evolutionarily relevant process. Biological systems persist in space and time by transfor ming energy from one state (...) to another in a manner that generates structures which allows the system to continue to persist. Two classes of energetic transformations allow this; heat-generating transformations, resulting in a net loss of energy from the system, and conservative transformations, changing unusable energy into states that can be stored and used subsequently. All conservative transformations in biological systems are coupled with heat-generating transformations; hence, inherent biological production, or genealogical proesses, is positively entropic. There is a self-organizing phenomenology common to genealogical phenomena, which imparts an arrow of time to biological systems. Natural selection, which by itself is time-reversible, contributes to the organization of the self-organized genealogical trajectories. The interplay of genealogical (diversity-promoting) and selective (diversity-limiting) processes produces biological order to which the primary contribution is genealogical history. Dynamic changes occuring on times scales shorter than speciation rates are microevolutionary; those occuring on time scales longer than speciation rates are macroevolutionary. Macroevolutionary processes are neither redicible to, nor autonomous from, microevolutionary processes. (shrink)

Applications of learning to autonomous agents (simulated or real) have often been restricted to learning a mapping from perceived state of the world to the next action to take. Often this is couched in terms of learning from no previous knowledge. This general case for real autonomous robots is very difficult. In any case, when building a real robot there is usually a lot of a priori knowledge (e.g., from the engineering that went into its design) which doesn’t need to (...) be learned. We describe the behavior-based approach to autonomous robots, and then examine four classes of learning problems associated with such robots. (shrink)
This paper reviews the experience of 174 of Canada's largest 1500 public and private sector corporations which have begun to incorporate sustainable development management and reporting as part of their operations. Answers are provided to three main questions: Why have they implemented this initiative? What progress has been made in terms of sustainability audit practice – frequency, focus, organization of the audit team –, internal communication, and external reporting? And where has, and will the leadership for the sustainability audit movement (...) come from as why? Sustainable development auditing and reporting in Canada is voluntary. Practice varies from an elementary level to a sophisticated integrated assessment of social, environmental, labour, sourcing and trading, and governance issues. The depth of practice and experience in this area depends on several factors, including: corporate commitment, the degree of public perception of sector-wide environmental issues, exposure to legal liability, and the extent of dialogue and transparency associated with the auditing process. Differences of opinion about accounting and auditing standards as well as whether all, or parts of, audits should be independent are explored. The sources of data used for this paper include the EthicScan Corporate 1500 DataBase, The Corporate Ethics Monitor, various reports prepared by EthicScan Canada, and the consultancies of both authors.

We present a novel methodology for building humanlike artificially intelligent systems. We take as a model the only existing systems which are universally accepted as intelligent: humans. We emphasize building intelligent systems which are not masters of a single domain, but, like humans, are adept at performing a variety of complex tasks in the real world. Using evidence from cognitive science and neuroscience, we suggest four alternative essences of intelligence to those held by classical AI. These are the parallel themes (...) of development, social interaction, embodiment, and integration. Following a methodology based on these themes, we have built a physical humanoid robot. In this paper we present our methodology and the insights it affords for facilitating learning, simplifying the computation underlying rich behavior, and building systems that can scale to more complex tasks in more challenging environments.

In order to build autonomous robots that can carry out useful work in unstructured environments new approaches have been developed to building intelligent systems. The relationship to traditional academic robotics and traditional artificial intelligence is examined. In the new approaches a tight coupling of sensing to action produces architectures for intelligence that are networks of simple computational elements which are quite broad, but not very deep. Recent work within this approach has demonstrated the use of representations, expectations, plans, goals, and (...) learning, but without resorting to the traditional uses, of central, abstractly manipulable or symbolic representations. Perception within these systems is often an active process, and the dynamics of the interactions with the world are extremely important. The question of how to evaluate and compare the new to traditional work still provokes vigorous discussion. (shrink)
Complex systems and complex missions take years of planning and force launches to become incredibly expensive. The longer the planning and the more expensive the mission, the more catastrophic if it fails. The solution has always been to plan better, add redundancy, test thoroughly and use high quality components. Based on our experience in building ground based mobile robots (legged and wheeled) we argue here for cheap, fast missions using large numbers of mass produced simple autonomous robots that are small (...) b y today's standards (1 to 2 Kg). We argue that the time between mission conception and implementation can be radically reduced, that launch mass can be slashed, that totally autonomous robots can be more reliable than ground controlled robots, and that large numbers of robots can change the tradeoff between reliability of individual components and overall mission success. Lastly, we suggest that within a few years it will be possible at modest cost to invade a planet with millions of tiny robots. (shrink)
Both direct, and evolved, behavior-based approaches to mobile robots have yielded a number of interesting demonstrations of robots that navigate, map, plan and operate in the real world. The work can best be described as attempts to emulate insect level locomotion and navigation, with very little work on behavior-based non-trivial manipulation of the world. There have been some behavior-based attempts at exploring social interactions, but these too have been modeled after the sorts of social interactions we see in insects. But (...) thinking how to scale from all this insect level work to full human level intelligence and social interactions leads to a synthesis that is very different from that imagined in traditional Artificial Intelligence and Cognitive Science. We report on work towards that goal. (shrink)

At the MIT Arti cial Intelligence Laboratory we have been working on technologies for an Intelligent Room. Rather than pull people into the virtual world of the computer we are trying to pull the computer out into the real world of people.

We have built a layered architecture where at the bottom level vision systems track people and identify their activities and gestures, and through word spotting decide whether people in the room are talking to each other or to the room itself. At the next level an agent architecture provides a uniform interface to such specially built systems, and to other o the shelf software, such as web browsers, etc. At the highest level we are able to build application systems that provide occupants of the room with specialized services; examples we have built include systems for command and control situations rooms and as a room for giving presentations.

Abstract Companies in the stability operations industry have been subjected to painstaking scrutiny while critics have ignored the value they bring to contingency operations and government clients. Moreover, the scope of the industry is often overlooked by critics who paint a picture of uncontrollable companies making ridiculous profits. In response, this article offers some insight on stability operations, contracting processes, pitfalls, and opportunities. The article then discusses some of the criticisms that surround the industry. These criticisms are often due to (...) sensationalized reporting, and a significant problem is that reports on criminal activity such as fraud and abuse are exaggerated. In contrast, the far larger problem of waste due to poor client planning and oversight is glossed over. Finally, the article discusses industry self-policing efforts that have emerged to support the use of professional and compliant businesses in stability operations. Ultimately it is governmental regulatory enforcement and quality contracting practices that will do the most to marginalize unethical companies, reward better firms, and improve partnerships and success rates in stability operations globally.

This paper argues that Leif Wenar's theory of reparations is not purely forward-looking and that backward-looking considerations play an important role: if there had never been a past injustice, then reparations for the future cannot be acceptable. Past injustice compose the first part of a two-tiered theory of reparations. We must first discover a past injustice has taken place: reparations are for the repair of previous damage. However, for Wenar, not all past injustices warrant reparations. Once we have first passed (...) the initial test of demonstrating a past injustice has taken place, we then determine whether or not to finally accept reparations based upon forward-looking considerations. What is important to note is that this decision to award reparations is based upon forward-looking considerations, but only after first satisfying the test of a past injustice. Thus, backward-looking considerations make up an important first part of Wenar's two-tiered theory of reparations. It is not my argument that this theory is unsafe and I find Wenar's arguments both novel and highly compelling. However, the view that this theory is forward-looking -- and not backward-looking -- is not entirely accurate. My brief reply corrects this part of an important new theory of reparations in the hope of strengthening its persuasive power. (shrink)
This article examines the pressures and players that have shaped business ethics in Canadian corporations, and reports on the status of Canadian corporate social performance in 1995. Business in Canada has not been subject, up to 1996, to a powerful national institutional framework such as the US Securities and Exchange Commission and the Foreign Corrupt Practices Act. Consequently, business ethics in Canada have developed primarily in response to broader socio-political and socio-economic factors than in the US, and will probably continue (...) to do so. Interestingly, the issues, policies and practices developed in Canada may provide insights for US corporations as they respond to broadened pressures. Business ethics in Canada, on the other hand, will benefit increasingly from the US experience as pressures grow for national regulation and statutes governing corruption. (shrink)
Executives, professionals, educators and labour leaders are requesting an update on corporate ethical trends.

An analysis follows of how corporations are responding to this interest, and of how that response might be enhanced through improved second-generation codes of ethical performance.
We describe an algorithm which allows a behavior-based robot to learn on the basis of positive and negative feedback when to activate its behaviors. In accordance with the philosophy of behavior-based robots, the algorithm is completely distributed: each of the behaviors independently tries to find out (i) whether it is relevant (ie. whether it is at all correlated to positive feedback) and (ii) what the conditions are under which it becomes reliable (i.e. the conditions under which i t maximizes the (...) probability of receiving positive feedback and minimizes the probability of receiving negative feedback). The algorithm has been tested successfully on an autonomous 6-legged robot which had to learn how to coordinate its legs so as to walk forward. (shrink)
There are a number of reasons to be interested in building humanoid robots. They include (1) since almost all human artifacts have been designed to easy for humans to interact with, humanoid robots provide backward compatibility with the existing human constructed world, (2) humanoid robots provide a natural form for humans to operate through telepresence since they have the same kinematic design as humans themselves, (3) by building humanoid robots that model humans directly they will be a useful tool in (...) understanding how humans develop and operate as they provide a platform for experimenting with different hypotheses about humans and (4) humanoid robots, given su cient abilities, will present a natural interface to people and people will be able to use their instinctive and culturally developed subconscious techniques for communicating with other people to communicate with humanoid robots. In this paper we take reason (4) seriously, and examine some of the technologies that are necessary to make this hope a reality. (shrink)
The uniqueness of human cognition and language has long been linked to systematic changes in developmental timing. Selection for postnatal skeletal ossification resulted in progressive prolongation of universal patterns of primate growth, lengthening infancy, childhood, and adolescence. Language emerged as communication increased in complexity within and between communities rather than from selection for some unique features of childhood or adolescence, or both.
Both direct, and evolved, behavior-based approaches to mobile robots have yielded a number of interesting demonstrations of robots that navigate, map, plan and operate in the real world. The work can best be described as attempts to emulate insect level locomotion and navigation, with very little work on behavior-based non-trivial manipulation of the world. There have been some behavior-based attempts at exploring social interactions, but these too have been modeled after the sorts of social interactions we see in insects. But (...) thinking how to scale from all this insect level work to full human level intelligence and social interactions leads to a synthesis that is very di erent from that imagined in traditional Arti cial Intelligence and Cognitive Science. We report on work towards that goal. (shrink)
Proponents of two axioms of biological evolutionary theory have attempted to find justification by reference to nonequilibrium thermodynamics. One states that biological systems and their evolutionary diversification are physically improbable states and transitions, resulting from a selective process; the other asserts that there is an historically constrained inherent directionality in evolutionary dynamics, independent of natural selection, which exerts a self-organizing influence. The first, the Axiom of Improbability, is shown to be nonhistorical and thus, for a theory of change through time, (...) acausal. Its perception of the improbability of living states is at least partially an artifact of closed system thinking. The second, the Axiom of Historically Determined Inherent Directionality, is supported evidentially and has an explicit historical component. Historically constrained dynamic populations are inherently nonequilibrium systems. It is argued that living, evolving systems, when considered to be historically constrained nonequilibrium systems, do not appear improbable at all. Thus, the two axioms are not compatible. Instead, the Axiom of Improbability is considered to result from an unjustified attempt to extend the contingent proximal actions of natural selection into the area of historical, causal explanations. It is thus denied axiomatic status, and the effects of natural selection are subsumed as an additional level of constraint in an evolutionary theory derived from the Axiom of Historically Determined Inherent Directionality.

The majority of North American corporations awakened to the need for their own ethical guidelines during the late 1970s and early 1980s, even though modern corporations are subject to a surprising multiplicity of external codes of ethics or conduct. This paper provides an understanding of both internal and external codes through a discussion of the factors behind the development of the codes, an analysis of internal codes and an identification of problems with them.
We agree that treating rules and similarity as dichotomous opposites is unproductive. However, describing all categorization operations as a continuum of varied similarity process obscures a multidimensional contrast. We describe two processes, instantiated rules and abstract analogy, both of which have aspects of rules and similarity, and question whether they can be compared informatively as points on a continuum.
Mahādeviyakka was a radical 12th century Karnataka saint of whom surprisingly little has been written. Considered the most poetic of the Virashaivas, her vacanas are characterized by their desperate searching for Shiva. I attempt to convey Mahādevi's epistemology and its struggle to 'know' Shiva, necessitating a lifetime of searching for him; offer an interpretation of the innate presence of iva in the world and its consequences for epistemology; and explore the sense of tragic love inherent in devotional searching for Shiva. (...) My primary goal is to offer a powerful and positive, yet critical, interpretation of Mahādevi's beautiful prose on her relationship with Shiva. (shrink)
This article explores the kind of detachment needed to conduct comparative law scholarship and teaching, as well as implement its application to practical problems. The full and fair comparison of the law requires a cosmopolitan view which embodies some degree of detachment from adherence to the laws of one's ``home". The Enlightenment efforts to build a science of comparative law to achieve this detachment failed. Modern inheritors of the Enlightenment approach have similarly failed. In a series of articles, I argue (...) that we must return to the ancient effort to achieve a new ``objectivity" through Hellenic deliberation, Hellenistic detachment, Roman rhetoric, Christian dialectic and the canonics of the empire's codification process. This article focuses upon the Hellenistic contributions to achievement of cosmopolitan detachment. The Cynic, Skeptic Stoic and Epicurean doctrines and ethical education offer an alternative route to the detachment necessary for a comparative law. (shrink)
This study addresses how moral judgment development, authenticity, and nonprejudice account for variance in scores pertaining to various motivational functions underlying volunteerism in order to clarify certain problems associated with previous research that has considered such relationships. In the study, 127 participants completed measurements that pertain to these constructs. Correlations revealed that moral judgment had a negligible relationship with both authenticity and nonprejudice, thereby affirming that the former construct is distinct from the latter two. Linear regression analyses supported that moral (...) judgment development and nonprejudice provided the strongest contributions to the variance of the considered indices of volunteer motivation. The motivational function underlying volunteerism was also recognized as an important factor that pertains to the observed contributions of variance. Findings are discussed in concert with and compared to prior considerations of relationships between moral judgment development and considerations of the moral self. Implications where moral education is concerned are also considered. (shrink)
