Humans can learn complex functional relationships between variables from small amounts of data. In doing so, they draw on prior expectations about the form of these relationships. In three experiments, we show that people learn to adjust these expectations through experience, learning about the likely forms of the functions they will encounter. Previous work has used Gaussian processes—a statistical framework that extends Bayesian nonparametric approaches to regression—to model human function learning. We build on this work, modeling the process of learning (...) to learn functions as a form of hierarchical Bayesian inference about the Gaussian process hyperparameters. (shrink)

Since the cognitive revolution, psychologists have developed formal theories of cognition by thinking about the mind as a computer. However, this metaphor is typically applied to individual minds. Humans rarely think alone; compared to other animals, humans are curiously dependent on stores of culturally transmitted skills and knowledge, and we are particularly good at collaborating with others. Rather than picturing the human mind as an isolated computer, we can imagine each mind as a node in a vast distributed system. Viewing (...) human cognition through the lens of distributed systems motivates new questions about how humans share computation, when it makes sense to do so, and how we can build institutions to facilitate collaboration.

By closely examining the sources, movements, and persons of the Renaissance and the Reformation, Voegelin reveals the roots of today's political ideologies in this fourth volume of his _History of Political Ideas._ This insightful study lays the groundwork for Voegelin's critique of the modern period and is essential to an understanding of his later analysis. Voegelin identifies not one but two distinct beginnings of the movement toward modern political consciousness: the Renaissance and the Reformation. Historically, however, the powerful effects of (...) the second have overshadowed the first. In this book, Voegelin carefully examines both periods and their presence in modern thought. The Renaissance, represented by the works of Niccolò Machiavelli, Desiderius Erasmus, and Thomas More, is characterized by a struggle for balance. Machiavelli and Erasmus both looked to a virtuous prince to achieve order, one calling for brute force and the other for Christian spirituality to reach their goal. Also a participant in the first beginning of modernity, More was a complex thinker identified as a saint both of the church and of the communist movement. The issues he explored in _Utopia,_ as Voegelin demonstrates, indirectly gave rise to concepts that have profoundly affected Western history: colonization, imperialism, national socialism, and communism. Exploring the transition from the Renaissance to the Reformation is a brilliant chapter, "The People of God," which examines the sectarian movement. These pages contain the rich historical background that led to Voegelin's later conclusions about Gnosticism and its modern influences. Voegelin offers a controversial view of the Reformation as well as the political and religious situation directly preceding it. Yet he sheds light on the strengths and inadequacies of its key figures, Martin Luther and John Calvin. The driving force behind the Reformation stemmed solely from the powerful personality of Luther. What began as an abstract, purely technical discussion developed into a full-blown revolt. Later in the period, Calvin confronted the problems left behind by Luther and endeavored to create his own universal church to supplant the Catholic Church. His theory of a new elite would have a distinct impact on history. By examining the political ideas that first emerged during the Renaissance and Reformation, this fascinating volume provides a foundation for understanding the events of centuries to follow.

Iconicity, or the resemblance between form and meaning, is often ascribed to a special status and contrasted with default assumptions of arbitrariness in spoken language. But does iconicity in spoken language have a special status when it comes to learnability? A simple way to gauge learnability is to see how well something is retrieved from memory. We can further contrast this with guessability, to see (1) whether the ease of guessing the meanings of ideophones outperforms the rate at which they (...) are remembered; and (2) how willing participants’ are to reassess what they were taught in a prior task—a novel contribution of this study. We replicate prior guessing and memory tasks using ideophones and adjectives from Japanese, Korean, and Igbo. Our results show that although native Cantonese speakers guessed ideophone meanings above chance level, they memorized both ideophones and adjectives with comparable accuracy. However, response time data show that participants took significantly longer to respond correctly to adjective–meaning pairs—indicating a discrepancy in a cognitive effort that favored the recognition of ideophones. In a follow‐up reassessment task, participants who were taught foil translations were more likely to choose the true translations for ideophones rather than adjectives. By comparing the findings from our guessing and memory tasks, we conclude that iconicity is more accessible if a task requires participants to actively seek out sound‐meaning associations. (shrink)

We provide a retrospective of 25 years of the International Conference on AI and Law, which was first held in 1987. Fifty papers have been selected from the thirteen conferences and each of them is described in a short subsection individually written by one of the 24 authors. These subsections attempt to place the paper discussed in the context of the development of AI and Law, while often offering some personal reactions and reflections. As a whole, the subsections build into (...) a history of the last quarter century of the field, and provide some insights into where it has come from, where it is now, and where it might go.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

Photography matters, writes Jerry Thompson, because of how it works -- not only as an artistic medium but also as a way of knowing. It matters because how we understand what photography is and how it works tell us something about how we understand anything. With these provocative observations, Thompson begins a wide-ranging and lucid meditation on why photography is unique among the picture-making arts. Thompson, a working photographer for forty years, constructs an argument that moves with (...) natural logic from Thomas Pynchon to Jonathan Swift to Plato to Emily Dickinson to detailed readings of photographs by Eugène Atget, Garry Winogrand, Marcia Due, Walker Evans, and Robert Frank. He questions Susan Sontag's assertion in On Photography that "nobody" can any longer imagine literate, authoritative, or transcendent photographs. He considers the money-fueled expansion of the market for photography, and he compares ambitious "meant-for-the-wall" photographs with smaller, quieter works. Forcefully and persuasively, Thompson argues for photography as a medium concerned with understanding the world we live in -- a medium whose business is not constructing fantasies pleasing to the eye or imagination but describing the world in the toughest and deepest way.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

_The Laws_, Plato's longest dialogue, has for centuries been recognized as the most comprehensive exposition of the _practical_ consequences of his philosophy, a necessary corrective to the more visionary and utopian _Republic_. In this animated encounter between a foreign philosopher and a powerful statesman, not only do we see reflected, in Plato's own thought, eternal questions of the relation between political theory and practice, but we also witness the working out of a detailed plan for a new political order that (...) embodies the results of Plato's mature reflection on the family, the status of women, property rights, criminal law, and the role of religion and the fine arts in a healthy republic. "Because it succeeds in being both literal and comprehensive, it is by far superior to any translation available. By reproducing dramatic detail often omitted, such as oaths, hesitations, repetitions, and forms of address, Pangle allows the reader to follow the dialogue's interplay between argument and dramatic context.... Pangle's translation captures the excitement and the drama of Plato's text."—Mary P. Nichols, _Ancient Philosophy_ "Pangle's achievement is remarkable.... The accompanying interpretive essay is an excellent distillation of a dialogue three times its size. The commentary is thoughtful, even profound; and it amply demonstrates the importance of reading Plato carefully and from a translation that is true to his language."—Patrick Coby, _American Political Science Review_.

The Spirit of the Laws —Montesquieu’s huge, complex, and enormously influential work—is considered one of the central texts of the Enlightenment, laying the foundation for the liberally democratic political regimes that were to embody its values. In his penetrating analysis, Thomas L. Pangle brilliantly argues that the inherently theological project of Enlightenment liberalism is made more clearly—and more consequentially— in Spirit than in any other work. _ In a probing and careful reading, Pangle shows how Montesquieu believed that rationalism, (...) through the influence of liberal institutions and the spread of commercial culture, would secularize human affairs. At the same time, Pangle uncovers Montesquieu’s views about the origins of humanity’s religious impulse and his confidence that political and economic security would make people less likely to sacrifice worldly well-being for otherworldly hopes. With the interest in the theological aspects of political theory and practice showing no signs of diminishing, this book is a timely and insightful contribution to one of the key achievements of Enlightenment thought.

Contemporary moral philosophers have produced an enormous amount of rich and varied published work on virtually all the issues falling within the scope of ethics and moral philosophy. Morality and the Good Life is a comprehensive survey of contemporary ethical theory that collects thirty-four selections on morality and the theory of value. Emphasizing value theory, metaethics, and normative ethics, it is non-technical and accessible to a wide range of readers. Selections are organized under six main topics: Concepts of Goodness What (...) Things are Good? Virtues and Ethics Realism vs. Anti-Realism Value and Obligation The Value and Meaning of Life The text includes both a substantial general introduction featuring explanatory summaries of all the selections and an extensive topical bibliography, which enhance the volume's research and pedagogical utility. The most up-to-date and wide-ranging survey of its kind, Morality and the Good Life is ideal for advanced undergraduate and graduate courses in contemporary ethical theory, moral philosophy, and theory of value.

Few moral questions have greater bearing on the conduct of our everyday lives than questions about the morality of lying. These questions are also important for ethical theory. An important test of any theory of right and wrong is whether it gives an adequate account of the morality of lying. Conceptual questions about the nature of lying are prior to questions about the moral status of lying. Any theory about the moral status of lying presupposes an account of what lying (...) is.

For as long as humans have pondered philosophical issues, they have contemplated the good life. Yet most suggestions about how to live a good life rest on assumptions about what the good life actually is. Thomas Carson here confronts that question from a fresh perspective. Surveying the history of philosophy, he addresses first-order questions about what is good and bad as well as metaethical questions concerning value judgments. Carson considers a number of established viewpoints concerning the good life. He (...) offers a new critique of Mill's and Sidgwick's classic arguments for the hedonistic theory of value, employing thought experiments that invite us to clarify our preferences by choosing between different kinds of lives. He also assesses the desire- or preference-satisfaction theory of value in detail and takes a fresh look at both Nietzsche's Übermensch ideal and Aristotle's theory of the good life. In exploring foundational questions, Carson observes that many established theories rest on undefended assumptions about the truth of moral realism. Arguing against this stand, he defends the view that good means desirable and presents a divine-preference version of the desire-satisfaction theory. In this he contends that, if there exists a kind and omniscient God who created the universe, then what is good or bad is determined by His preferences; if such a God does not exist, what is good or bad depends on what we as rational humans desire. Value and the Good Life is the only book that defends a divine-preference theory of value as opposed to a divine-command theory of right and wrong. It offers a masterfully constructed argument to an age-old question and will stimulate all who seek to know what the good life truly is. (shrink)

This paper addresses the following three claims that Frankfurt makes about the concept of bullshit:1. Bullshit requires the intention to deceive others.2. Bullshit does not constitute lying.3. The essence of bullshit is lack of concern with the truth of what one says.I offer counterexamples to all three claims. By way of defending my counterexamples, I examine Cohen’s distinction between bullshiting and bullshit and argue that my examples are indeed cases of bullshiting that Frankfurt’s analysis is intended to cover. My examples (...) of bullshitters who are very concerned to say only things that are true show that Frankfurt is mistaken in claiming that the “essence” of bullshit is lack of concern with the truth of what one says.

My interest in the issues considered here arose out of my great frustration in trying to attack the all-pervasive relativism of my students in introductory ethics courses at Virginia Polytechnic Institute and State University. I am grateful to my students for forcing me to take moral relativism and skepticism seriously and for compelling me to argue for my own dogmatically maintained version of moral objectivism. The result is before the reader. The conclusions reached here (which can be described either as (...) a minimal objectivism or as a moderate verson of relativism) are considerably weaker than those that I had expected and would have liked to have defended. I have arrived at these views kicking and screaming and have resisted them to the best of my ability. The arguments of this book are directed at those who deny that moral judgments can ever be correct (in any sense that is opposed to mistaken) and who also deny that we are ever rationally com pelled to accept one moral judgment as opposed to another. I have sought to take their views seriously and to fight them on their own grounds without making use of any assumptions that they would be unwilling to grant. My conclusion is that, while it is possible to refute the kind of extreme irrationalism that one often encounters, it is impossible to defend the kind of objectivist meta-ethical views that most of us want to hold, without begging the question against the non-objectivist.

This paper presents an analysis of bluffing in labor negotiations from legal, economic, and ethical perspectives. It is argued that many forms of bluffing in labor negotiations are legal and economically advantageous, but that they typically constitute lying. Nevertheless it is argued that it is generally morally acceptable to bluff given a typical labor-management relationship where one's negotiating partner is familiar with and most likely employing bluffing tactics him/herself. We also consider whether it is an indictment of our present negotiating (...) practices and our economic system as a whole that, given the harsh realities of the marketplace, bluffing is usually morally acceptable.

Standard definitions of lying imply that intending to deceive others is a necessary condition of one's telling a lie. In an earlier paper, which appeared in this journal, Wokutch, Murrmann and I argued that intending to deceive others is not a necessary condition of one's telling a lie and proposed an alternative definition. In a reply which also appeared in this journal, Gary Jones argues that our arguments fail to establish the claim that it is possible to lie without intending (...) to deceive others, and that the objections which we raise for standard definitions apply equally to our own. The present paper argues that one can lie without intending to deceive others. I concede Jones' second criticism and propose a new alternative definition. (shrink)

This paper examines several issues regarding deception in advertising. Some generally accepted definitions are considered and found to be inadequate. An alternative definition is proposed for legal/regulatory purposes and is related to a suggested definition of the term deception as it is used in everyday language. Based upon these definitions, suggestions are offered for detecting and regulating deception in advertising. This paper additionally considers the grounds for the generally held but largely unquestioned assumption that deceptive advertising is unethical. It is (...) argued that deceptive advertising can be shown to be morally objectionable, on the weak assumption that it is prima facie wrong to harm others. Finally, the implications of this analysis with respect to current regulation of deceptive advertising by the FTC are considered. (shrink)

This paper has two distinct objectives. (1) I defend an analysis of the concept of a conflict of interest. On my analysis the concept of a conflict of interest is broader than is generally supposed. I argue that a very large class of cases not ordinarily regarded as conflicts of interest should be so regarded. Conflicts of interest are an integral feature of many professional relationships and do not (as is often supposed) require the existence of external financial or personal (...) relationships. (2) I defend and explain the commonsense view that conflicts of interest areprima facie wrong and argue that in ordinary cases it is wrong, all things considered, to allow an avoidable conflict of interest to occur. I attempt to establish these claims on the basis of weak and relatively noncontroversial assumptions. (shrink)

This paper focuses on the 1986 Amendments to the False Claims Act of 1863, which offers whistle-blowers financial rewards for disclosing fraud committed against the U.S. government. This law provides an opportunity to examine underlying assumptions about the morality of whistle-blowing and to consider the merits of increased reliance on whistle-blowing to protect the public interest. The law seems open to a number of moral objections, most notably that it exerts a morally corrupting influence on whistle-blowers. We answer these objections (...) and argue that the law is not objectionable on these grounds. Since there are no compelling moral objections to the law, it is appropriate and acceptable to judge the law in terms of its economic costs and benefits. We assess the most salient of these and conclude that the benefits outweigh the costs. We suggest that a mechanism similar to the Act should be considered for protecting stockholders’ interests in the private sector. We conclude by making several proposals for improving the existing legislation. (shrink)

While many (perhaps most) of those engaged in the study of philosophy would accept the continued reality and importance of an analytic/continental divide in the discipline, there has been no serious examination of the political dimensions of this rift. Here a series of political assumptions are revealed to be widely held among the British analytic philosophers who were active during the period in which the analytic/continental divide was being established. This paper will approach demonstrating the analysts’ beliefs about the political (...) affiliations of continental philosophy in three ways. Firstly, it will produce direct evidence of the analysts’ belief in the relationship between 19th century continental philosophy and various politically undesirable regimes. Secondly, it will examine in detail one illustrative example, that of Hegel.

The recent accounting scandals at Enron, WorldCom, and other corporations have helped to fuel a massive loss of confidence in the integrity of American business and have contributed to a very sharp decline in the U.S. stock market. Inasmuch as these events have brought ethical questions about business to the forefront in the media and public consciousness as never before, they are of signal importance for the field of business ethics. I offer some observations and conjectures about the bearing of (...) the recent scandals on the literature on business ethics. I defend the following contentions: 1. Recent events reveal serious weaknesses of the stakeholder theory about the social responsibilities of business which lacks prohibitions against fraud and deception. This is a glaring deficiency of standard versions of the stakeholder theory, but it is easily remedied by adding explicit prohibitions against fraud and deception. In addition, recent events highlight the stakeholder theory's very naive and unrealistic hopes and expectations for business executives as moral arbiters and agents of social improvement. 2. Recent events do not constitute an objection to the shareholder theory about the social responsibilities of business, however, these events make evident the implausibility of strong versions of the invisible hand theory. 3. Schemes of payment and reward often create perverse incentives for individuals to engage in unethical conduct. 4. Both the shareholder theory and the stakeholder theory need to add a constraint that requires executives to respect the professional obligations of employees. (shrink)

The goals and values of economic development strategies vary according to the individual communities that employ them. While economic development strategies are aimed at increasing jobs, income, and community wealth, the issue of who gains and who loses from economic change is often overlooked. The industrial development strategies of the 1960s and 1970s are giving way to local initiatives based on services. Although local efforts may mean greater local control, the globalization of the economy has exposed formerly remote areas to (...) international competition. The challenge to communities will be to achieve a moderate, steady, and manageable pace of “good” growth. Each community will ultimately need to develop a strategy for economic growth that matches community desires with community resources. (shrink)

Marr's levels of analysis—computational, algorithmic, and implementation—have served cognitive science well over the last 30 years. But the recent increase in the popularity of the computational level raises a new challenge: How do we begin to relate models at different levels of analysis? We propose that it is possible to define levels of analysis that lie between the computational and the algorithmic, providing a way to build a bridge between computational- and algorithmic-level models. The key idea is to push the (...) notion of rationality, often used in defining computational-level models, deeper toward the algorithmic level. We offer a simple recipe for reverse-engineering the mind's cognitive strategies by deriving optimal algorithms for a series of increasingly more realistic abstract computational architectures, which we call “resource-rational analysis.”.

Ian Maitland defends sweatshop labor on the grounds that “A wage or labor practice is ethically acceptable if it is freely chosen by informed workers” (he calls his view “the Classical Liberal Standard,” CLS). I present several examples of economic exchanges that are mutually beneficial and satisfy the requirements of the CLS, but, nonetheless, are morally wrong. Maitland’s arguments in defense of sweatshops are unsuccessful because they depend on the flawed “CLS.” My paper criticizes Maitland’s arguments in defense of sweatshops, (...) but I do not claim that his conclusions are false—I do not claim to have shown that the labor practices Maitland defends are morally wrong. I argue that some of the disagreements about sweatshops between Maitland and his critics depend on disagreements about the answers controversial questions in ethical theory. In the absence of definitive answers to those questions , there are no decisive arguments for or against Maitland’s view about sweatshops. (shrink)
