PurposeTo use the power of knowledge acquisition and machine learning in the development of a collaborative computer classification system based on the features of age-related macular degeneration (AMD).MethodsA vocabulary was acquired from four AMD experts who examined 100 ophthalmoscopic images. The vocabulary was analyzed, hierarchically structured, and incorporated into a collaborative computer classification system called IDOCS. Using this system, three of the experts examined images from a second set of digital images compiled from more than 1000 patients with AMD. Images (...) were annotated, and features were identified and defined. Decision trees, a machine learning method, were trained on the data collected and used to extract patterns. Interrelationships between the data from the different clinicians were investigated.ResultsSix drusen classes in the structured vocabulary were largely sufficient to describe all the identified features. The decision trees classified the data with 76.86% to 88.5% accuracy and distilled patterns in the form of hierarchical trees composed of 5 to 15 nodes. Experts were largely consistent in their characterization of soft, and to a lesser extent, hard drusen, but diverge in definition of other drusen. Size and crystalline morphology were the main determinants of drusen type across all experts.ConclusionsMachine learning is a powerful tool for the characterization of disease phenotypes. The creation of a defined feature set for AMD will facilitate the development of an IDOCS-based classification system. (shrink)

This book is the fruit of twenty-five years of study of Spinoza by the editor and translator of a new and widely acclaimed edition of Spinoza's collected works. Based on three lectures delivered at the Hebrew University of Jerusalem in 1984, the work provides a useful focal point for continued discussion of the relationship between Descartes and Spinoza, while also serving as a readable and relatively brief but substantial introduction to the Ethics for students. Behind the Geometrical Method is actually (...) two books in one. The first is Edwin Curley's text, which explains Spinoza's masterwork to readers who have little background in philosophy. This text will prove a boon to those who have tried to read the Ethics, but have been baffled by the geometrical style in which it is written. Here Professor Curley undertakes to show how the central claims of the Ethics arose out of critical reflection on the philosophies of Spinoza's two great predecessors, Descartes and Hobbes. The second book, whose argument is conducted in the notes to the text, attempts to support further the often controversial interpretations offered in the text and to carry on a dialogue with recent commentators on Spinoza. The author aligns himself with those who interpret Spinoza naturalistically and materialistically. (shrink)

There is good reason to take a virtue-based approach to business ethics. Moral principles are fairly useful in assessing actions, but understanding how moral people behave and how they become moral requires reference to virtues, some of which are important inbusiness. We must go beyond virtues and refer to character, of which virtues are components, to grasp the relationship between moralassessment and psychological explanation. Virtues and other character traits are closely related to (in technical terms, they superveneon) personality traits postulated (...) by personality psychologists. They may therefore be featured in respectable psychological explanations.But good character fits no familiar psychological pattern. A person of good character is sufficiently self-aware and rational that his or hervirtues are not accompanied by the vices that psychologists find usually associated with them. A course in business ethics can helpdevelop this self-awareness, which a good life in business requires. (shrink)

To teach that being ethical requires knowing foundational ethical principles – or, as Socrates claimed, airtight definitions of ethical terms – is to invite cynicism among students, for students discover that no such principles can be found. Aristotle differs from Socrates in claiming that ethics is about virtues primarily, and that one can be virtuous without having the sort of knowledge that characterizes mathematics or natural science. Aristotle is able to demonstrate that ethics and self-interest may overlap, that ethics is (...) largely compatible with common sense, and that Aristotle’s virtuous person can make ethical decisions rationally. Case studies can help students improve their ethical perception and keep their values from being overwhelmed by corporate culture. (shrink)

It may be nearly impossible to use standard principles to make a decision about a complex ethical case. The best decision, say virtue ethicists in the Aristotelian tradition, is often one that is made by a person of good character who knows the salient facts of the case and can frame the situation appropriately. In this respect ethical decisions and strategic decisions are similar. Rationality plays a role in good ethical decision-making, but virtue ethicists emphasize the importance ofintuitions and emotions (...) as well.Virtue ethics suggests a reconciliation of the factual and the normative. Virtues may explain as well as justify actions. The same is true of other psychological states and events. That psychological terms have normative implications does not render them useless in explanation. As Aristotle does not distinguish cleanly between the normative and empirical, so many moral philosophers today reject the is-ought dichotomy. They are prepared to learn from economists, psychologists,and other empirical scientists who offer information about the nature of the good life and of values. Social psychologists who study community or corporate culture suggest a close relationship between organizational and ethical features, much as Aristotle saw a close relationship between politics and ethics. We should infer from all this that in business ethics there is good reason for philosophers and organization scholars to work closely together. (shrink)

During the past decade many individuals have sought to create a connection between their work persona and their religious/spiritual persona. Management education has a legitimate role to play in introducing teachings drawn from our religious traditions into business ethics and other courses. Thereby, we can help prepare students to consider the possibility that business endeavors, spirituality and religious commitment can be inextricable parts of a coherent life.

A complex organization is in effect a commons, which supervisory techniques cannot preserve from free riding. A corporate culture strong enough to create the requisite community-minded second-order desires and beliefs may be morally illegitimate. What morality requires is not local enforcement of foundational moral principles-a futile undertaking-but that the organization be a good community in that it permits the disaffected to exit, encourages reflective consideration of morality and the good life, and creates appropriate loyalty.

Phillips and Margolis argue that moral philosophy is a poor basis for business ethics, but their narrow view of moral philosophywould exclude Aristotle, for one. They criticize me for assimilating states and organizations in using the Rawlsian device, but they puttoo much faith in Rawls's distinction between states and voluntary organizations and pay too little attention to the continuities betweenthem. Their plea for a conceptually autonomous ethics for organizations I interpret as reasonable and largely compatible with my ownstated opinion.

Behaviorism is consistent with the assumptions of perfect competition, with the homo economicus model, and with a form of ethics that enshrines market-based notions of utility, justice, and rights and encourages rational maximizing. Economics and business courses foster this deficient form of ethics, assuming an overriding desire for money, which, according to MacIntyre and Aristotle, crowds out the associative virtues. These beliefs, often associated with Taylor and Friedman, lead to such practices as incentive compensation, which would be effective only if (...) employees were homines economici and thus rational in the sense of knowing how to satisfy whatever desires they have. Against Davidson’s view that psychology cannot be a natural science, Aristotle believes that there can be a teleological, if not exact, science of behavior. Aristotle believes that emotions and objectives may be rational or irrational. But rationality—phronesis, practical wisdom—is not a matter of applying algorithms. Doris questions whether character generates the first premises of an agent’s practical syllogisms, while Haidt has argued that we often act on emotions rather than on the basis of the reasons that we claim motivate us. Aristotle agrees that many people are not virtuous and that weakness of the will is a common occurrence, and he agrees that emotion drives actions. But if you are virtuous, your emotions and desires support your rationality. Aristotle gives us reason to reject the notion that people are homines economici and to treat them as rational deliberators, in part by creating an appropriate culture. The claim that it is in the nature of human beings to deliberate rationally is in part aspirational, but also in part scientific—in Aristotle’s modest sense. (shrink)

Aristotelian naturalism is a good vantage point from which to consider the moral implications of evolution. Sociobiologists err in arguing that evolution is the basis for morality: not all or only moral features and institutions are selected for. Nor does the longevity of an institution argue for its moral status. On the other hand, facts about human capacities can have implications concerning human obligations, as Aristotle suggests. Aristotle’s eudaimonistic approach to ethics suggests that the notion of interests is far subtler (...) than many have realized, and leaves open the possibility that cooperativeness may be adaptive, virtuous, and a good thing for the agent. Lawrence and Nohria argue along remarkably similar lines, and they provide evidence against those who would question the existence of character. But promising as the Aristotelian approach is, it seems to give an inadequate account of our moral responsibility to those who are not members of our community. (shrink)

From their inception, the social issues in management (SIM) field and the SIM Division within the Academy of Management have provided venues to examine the complex, dynamic, two-way relation between economic institutions of our society and the social systems in which they operate. They have blended the normative with the scientific, the speculative with the empirical, and the philosophical with the pragmatic. The field and the Division have served, perhaps most importantly, as the conscience of management education and the Academy. (...) Their enduring quest and raison d’étre is to foster corporate capitalism that is accountable, ethical, and humane. (shrink)

We have reached a rough moral consensus in the field of business ethics. We believe in capitalism with a safety net and enoughregulation to deal with serious market imperfections. We favor autonomy for individuals and democracy for governments, thoughnot necessarily for organizations. We recognize the rights of citizens and the different rights of employees. We respect a variety of possible sets of values, and so countenance a distinction between public and private. In other words, we are capitalists, pluralists, and liberals. (...) But globalization will force us and businesspeople who share our views to deal with significant stakeholders who do not. The 21st century will see the accelerating pace of globalization. The great challenge for business ethics, for its philosophers and its scholars of business, will be to identify and advocate morality that takes adequate account of globalization, and that in so doing avoidsuntenable parochialism without falling into relativism.

This essay addresses directions for the Social Issues in Management (SIM) Division from the perspective of “Back to the Future.” The author was chair of the SIM Division in 1983 to 1984 and the 1989 recipient of the SIM Division’s Sumner Marcus Distinguished Service Award. The essay reviews the general history of SIM during the 1960s and 1970s in which the University of California, Berkeley, played a key role in organizing conferences. The author explains his approach as an applied empiricist (...) to research concerning SIM. The essentials are power, legitimacy, responsibility, rationality, and values, and understanding how they impact the ongoing day-to-day interactions within, between, and among business organizations, their leadership, and other sectors of society. SIM is a field of diverse inquiry which has been the recipient of perspectives and persons drawn not only from multiple disciplines, particularly from the social sciences, law, and management, but also from the humanities and sciences. SIM is patently multi- and inter-disciplinary. (shrink)

Christopher McMahon links political theory and business ethics and thereby takes the latter to a new level of philosophical sophistication. McMahon argues that legitimate authority, political or managerial, characteristically preempts certain of one’s judgments, so that one may reasonably submit to a directive to do something that contravenes one’s principles. Authoritative preemption does not involve weighing reasons pro and con, as one who is considering breaking a promise must do: it disqualifies competing considerations.

This article reviews the development of business ethics and corporate social policy from the perspective of a long-time major in the field.

In the opening lines of Aristophanes' Acharnians, Dicaeopolis counts first among his greatest joys ‘the five talents Cleon coughed up’, and he professes his love of the Knights for this service ‘worthy of Hellas’. The ancient scholiast gave what he thought an obvious explanation from Theopompus : he tells us that Cleon was accused of taking bribes to lighten the tribute of the islanders, and he was then fined ‘because of the outrage against the Knights’. Evidently Theopompus connected the charges (...) against Cleon with some earlier proceedings instigated by Cleon against the Cavalry. There is, as often, some difficulty in determining what Theopompus said and what the scholiast inferred, and, aside from that editorial problem, the scholiast's all-too-simple solution faces at least three major objections regarding the legal and political implications of such a trial. On the strength of such objections it was long ago supposed that Dicaeopolis rejoices not at a recent political defeat for the demagogue, but in recalling a theatrical expose in Babylonians of the previous year. This theory of a stage trial, however, encounters obstacles of its own in any reconstruction of the lost play. In recent work there have been many comments but no altogether satisfactory solution on this problem. It is the view of many that Cleon indeed suffered some political defeat in the year preceding Ach.; but, by this approach, ingenious solutions are required to make sense of the scholia. The assumption of a stage-trial, involving the Knights and Cleon in Babylonians, is still found persuasive by others, but if we are to discount the fragment of Theopompus, which has supporting testimony elsewhere in the scholiastic tradition, we would like to have something more than mere inference that Cleon was tried and convicted in Babylonians. The purpose of this paper is to find a more cogent explanation for these lines in Ach. and the equally puzzling scenario in Theopompus. It will be helpful to begin with the broad outlines of the problem, and then proceed to re-examine the prevailing views, the stage-trial theory and historical theories based upon the scholia.

We typically test norms with reference to their usefulness in dealing with social problems and issues, though sometimes we use hypernorms to evaluate them. The hypernorms that we find most acceptable do not guide action in the way local norms do. They do, however, raise challenging questions that we should ask in evaluating any practice and its associated norms. In this respect, they differ from the principles associated with traditional, as opposed to modern, morality. As societies become more alike, in (...) part as a result of globalization, they will face increasingly similar problems. Then their local norms will be more similar, and they will be more likely to share hypernorms. Insofar as we can agree to try to justify our hypernorms, we are likely to converge on the hypernorms characteristic of modern rather than traditional morality. But people are often attached to their old norms and so are not very good at seeing how hypernorms raise questions that challenge the old norms. Here moral imagination should aid in the adjustment process. A system of democratic capitalism is hospitable to a good kind of moral convergence. (shrink)

In this paper, I examine the thought of Descartes and Spinoza regarding the immortality of the soul. I conclude that Descartes’s argument(s) for the immortality of the soul—or at least the argument(s) that one can construct based on Descartes’s texts—are disappointing, and that Spinoza’s thought on the soul and its relation to the body leaves little room for the traditional doctrine of personal immortality.

Aristotle holds that virtue is more important to ethics than is following principles, though principles count for something. To act virtuously requires finding a mean between two bad extremes, such as cowardice and foolhardiness. This in turn requires the ability to see which details of a case are salient – or, in Aristotle’s terms, what the essence of the situation is. The enabling faculty Aristotle calls perception. Werhane’s account of moral imagination is similar. Perception can go wrong, according to Aristotle, (...) when we apply the wrong principle to a situation because we do not see the situation for what it really is. This Werhane calls failure of moral imagination.Werhane claims that organizations as well as individuals can have moral imagination. Aristotle believes, somewhat similarly, that one’s community deeply affects one’s character, hence one’s ability to perceive correctly. There remains a problem about finding a mean between the extremes of isolation and surrender of one’s autonomy. (shrink)

A análise da correspondência entre Espinosa e L. van Velthuysen pode ser bastante útil para aperfeiçoar nossa compreensão do Tractatus theologico-politicus e da filosofia de Espinosa em geral. Em sua correspondência, Espinosa é freqüentemente evasivo e lento para ver (ou, ao menos, para reconhecer) um ponto. É uma questão interessante como deveríamos dar conta destas deficiências em suas respostas, e sua correspondência com Velthuysen seria uma boa oportunidade para provar a perspectiva de Bennett. O artigo está dividido em três partes: (...) 1) Velthuysen antes de Espinosa e o contexto de suas críticas; 2) um exame das Cartas 42 e 43; e 3) o debate em torno do deísmo e do ateísmo. (shrink)

In this article, I want to draw attention to one strand ofthe complex web of processes that are involved when people group others, including themselves, into social categories. I will focus on the tendency to treat members of one's own group more favorably than nonmembers, a tendency that has been called ingroup favoritism. The structure of the article has three parts. First I will offer anevolutionary argument as to why ingroup favoritism, or something very much like it, is required by (...) theories of the evolution of altruism. I will then review some of the basic social psychological research findings dealing with social categorization generally, and ingroup favoritism specifically. Finally, I will examine two problems in business ethics from the point of view of ingroup favoritism to suggest ways in which social psychological principles and findings may be mobilized to help solve problems of racial or gender discrimination in business contexts.
