We prove that the problem of determining the minimum propositional proof length is NP- hard to approximate within a factor of 2 log 1 - o(1) n . These results are very robust in that they hold for almost all natural proof systems, including: Frege systems, extended Frege systems, resolution, Horn resolution, the polynomial calculus, the sequent calculus, the cut-free sequent calculus, as well as the polynomial calculus. Our hardness of approximation results usually apply to proof length measured either by (...) number of symbols or by number of inferences, for tree-like or dag-like proofs. We introduce the Monotone Minimum (Circuit) Satisfying Assignment problem and reduce it to the problems of approximation of the length of proofs. (shrink)

Alan Turing’s 1950 imitation game has been widely understood as a means for testing if an entity is intelligent. Following a series of papers by Diane Proudfoot, I offer a socio-technological interpretation of Turing’s paper and present an alternative way of understanding both the imitation game and Turing’s concept of intelligence. Turing, I claim, saw intelligence as a social concept, meaning that possession of intelligence is a property determined by society’s attitude toward the entity. He realized that as long as (...) human society held a prejudiced attitude toward machinery—seeing machines a priori as mindless objects—machines could not be said to be intelligent, by definition. He also realized, though, that if humans’ a priori, chauvinistic attitude toward machinery changed, the existence of intelligent machines would become logically possible. Turing thought that such a change would eventually occur: He believed that when scientists overcome the technological challenge of constructing sophisticated machines that could imitate human verbal behavior—i.e., do well in the imitation game—humans’ prejudiced attitude toward machinery will have altered in such a way that machines could be said to be intelligent. The imitation game, for Turing, was not an intelligence test, but a technological aspiration whose realization would likely involve a change in society’s attitude toward machines. (shrink)

What effect does creativity have on individuals, groups and societies, and on the fundamental values on which they base their actions and institutions? What constitutes good and evil, right and wrong, and how does creativity disrupt these beliefs? The Ethics of Creativity brings together an impressive collaboration of thinkers from several countries and disciplines to illuminate the thorny issues that arise when novel ideas and products brought forth by creativity collide with the rules and norms of what we believe to (...) be 'right' or 'good'. This book tackles questions of why most people claim to love creativity yet, in practice, may quash creative intentions, how creative innovations can create new ethical problems, when creativity and ethics tend to coincide and when they tend to conflict, and how both creativity and ethics might be harnessed to support a brighter future for all.

This paper presents a new approach to the demarcation of social emotions, based on their dependence on social appraisals that are designed to assess events bearing on social concerns. Previous theoretical attempts to characterize social emotions are compared, and their inconsistencies highlighted. Evidence for the present formulation is derived from theory and research into links between appraisals and emotions. Emotions identified as social using our criteria are also shown to bring more consistent consequences for social behavior than nonsocial emotions. We (...) conclude by considering ways of validating and refining our classification. (shrink)

Weiner’s attribution theory of motivation and emotion assumes emotions are determined by beliefs about causality. Individuals share a naïve understanding of this linkage between causal attribution and emotions and use it in order to draw inferences from and influence others’ emotions. Evidence for such uses is provided and recent research and theory that goes beyond the attribution–emotion linkage is discussed. Specifically, recent research considers the naïve use of a larger set of emotions and appraisals and their connections, and the role (...) of context in this process. However, still missing is a fuller understanding when this naïve knowledge is employed and how and when it is based on an explicit understanding of the emotion–appraisal linkage rather than more automatic processes.

Libertarian paternalism's notion of “nudging” refers to steering individual decision making so as to make choosers better off without breaching their free choice. If successful, this may offer an ideal synthesis between the duty to respect patient autonomy and that of beneficence, which at times favors paternalistic influence. A growing body of literature attempts to assess the merits of nudging in health care. However, this literature deals almost exclusively with health policy, while the question of the potential benefit of nudging (...) for the practice of informed consent has escaped systematic analysis. This article focuses on this question. While it concedes that nudging could amount to improper exploitation of cognitive weaknesses, it defends the practice of nudging in a wide range of other conditions. The conclusion is that, when ethically legitimate, nudging offers an important new paradigm for informed consent, with a special potential to overcome the classical dilemma between paternalistic beneficence and respect for autonomy.

A longstanding debate exists in both academic literature and popular culture about whether non-informative marketing tactics are manipulative. However, given that we tend to believe that some marketing tactics are manipulative and some are not, the question that marketers, their critics, and consumers need to ask themselves is that of how to actually determine whether any particular marketing tactic is manipulative and whether a given manipulative tactic is, in fact, immoral. This article proposes to operationalize criteria that can be used (...) by marketers for making such determinations and attempts to provide some clarification toward our under- standing of the concept of manipulation and the conditions for the moral acceptability of manipulative marketing practices. It argues that a marketing tactic is manipulative if it is intended to motivate by undermining what the marketer believes is his/her audience’s normal decision-making process either by deception or by playing on a vulnerability that the marketer believes exists in his/her audience’s normal decision-making process. Such a tactic is morally objectionable on several grounds, which make it morally impermissible unless outweighed by sufficient “redemptive” moral considerations. (shrink)

We reviewed 272 phase I oncology trial consent forms and then created an improved informed consent template in both English and Spanish by redesigning and rewording the consent form to be specific to phase I trials, to avoid repetition, and to use simplified language, identifiable sections framed by first-person questions, and tables to present information. The resulting consent form template is shorter than average and considerably easier to read . The template also meets the recommended eighth-grade maximum reading level for (...) consent forms. Use of this template should help improve the informed consent process. (shrink)

There is a disturbing kind of situation that presents agents with only two possibilities of moral action—one especially praiseworthy, the other condemnable. I describe such scenarios and argue that moral action in them exhibits a unique set of parameters: performing the commendable action is especially praiseworthy; not performing is not blameworthy; not performing is wrong. This set of parameters is distinct from those which characterize either moral obligation or supererogation. It is accordingly claimed that it defines a distinct, yet unrecognized, (...) deontic category, to which the name ‘Forced Supererogation’ is appropriate. The moral parameters of Forced Supererogation and the relations between them are discussed, especially the divergence of wrongness and blame. I argue that this new category allows a more accurate classification of moral actions than that imposed by the strained dichotomy of obligation versus supererogation. (shrink)

The nonidentity problem is a deep puzzle challenging the moral intuition that what is bad must be bad for someone. The first part of the paper constructs a new theory of harming, whereas the second part builds on the conclusions of the first to offer a new solution to the NIP. The first part discusses the neglected question of when a burden inflicted in the context of overall benefitting can be discretized as a separate entity—only when it can, is it (...) possible to identify the burden as harm, and only then is it possible to harm in bringing into overall good existence. The second part explains how, in those cases where creating is indeed harming, we can use the logic of concept expansion to construct a concept of wronging that applies to creation cases. (shrink)

Authority and Estrangement addresses a set of questions about self-knowledge and seeks to answer them in the context of the broader differences between the first-person and third-person perspectives on oneself. Attention to these broader differences takes the discussion from epistemology to moral psychology, and seeks to relate some of the issues of contemporary philosophy of mind to the concerns with self-consciousness in post-Kantian thought.

John Rawls, father of contemporary distributive justice, professed the metaphysical neutrality of his theory, and formulated an additional theory to support such neutrality generally. This article exposes Rawls’s own theological underpinnings concerning his conception of the moral arbitrariness of existence, and his structural dichotomous approach for engaging it. I show how both of his theories are reminiscent of Calvin, employing methods of bifurcation, and thus generating tensions within both the concept of justice and moral personality. I end with analysis of (...) the relationship of this structural rationality to arbitrariness. This exposure of Rawls’s theological debt is part of a wider argument concerning the theological basis of distributive justice theory, and the relevance of Theology for philosophical ethics.

Recent research, especially with functional brain imaging, demonstrated cases where the administration of a placebo produces objective effects in tissues that are indistinguishable from those of the real therapeutic agents. This phenomenon has been shown in treatments of pain, depression, Parkinsonism, and more. The main ethical complaint against placebo treatment is that it is a kind of deception, where supposedly we substitute what works just psychologically for a real drug that actually works on the tissue level. We claim that the (...) scientific findings bring to a new level the seeming deconstruction of the distinction between “placebo” and “real” drugs, and that instances of placebo treatment which fulfill this criterion should be recognized as a unique category—we call it “comparable placebo treatment” (CPT). The paper uses an analysis of the notion of deception to argue that CPT does not amount to deception; that it can preserve patient autonomy; and that it is therefore morally legitimate. (shrink)

ABSTRACTThis paper introduces the category of ‘non-deceptive manipulation that causes false beliefs’, analyzes how it narrows the traditional scope of ‘deception’, and draws moral implications.

The acclaimed and controversial historian turns his critical gaze on the writing of history today. Drawing on his four decades as a professional historian, Shlomo Sand interrogates the academic discipline of history, whose origin lay in the need for a national ideology. In the last few decades, traditional history has begun to fragment, yet only to give rise to a new role of historians as priests of official memory. Working in Israel has sharpened Sand's perspective, since the role of (...) history as national myth is particularly salient in a country where the Bible is treated as a history book. He asks such questions as: Is every historical narrative ideologically marked? Do political requirements and state power weigh down inordinately on historical research and teaching? And, in such conditions, can there be a morally neutral and 'scientific' truth? Despite his trenchant criticism of academic history, Sand would still like to believe that the past can be understood without myth, and sees pointers for this in the work of Weber and Sorel"--Provided by publisher.

Luck egalitarianism is an approach within current distributive justice theory which aims to focus redistributive efforts solely upon disadvantages that ensue from bad luck. This article considers how central assumptions and themes of both luck egalitarianism and its critics parallel those of providence theology and share some of their concerns. These relate to problems such as the basis of equality, the extent and nature of our knowledge, and of course, the paternalism that assessing people’s responsibility over their own disadvantages involves. (...) I highlight the similarity of luck egalitarianism to the role of providence and providence theory thinking, and particularly the tension between egalitarianism as a theological concept and the condescension inherent to imitatio Dei ethics. I approach these issues by analyzing standard criticisms of the luck egalitarian project, espoused by Susan Hurley and Elizabeth Anderson. I then proceed to assess the values of luck egalitarianism itself and consider different models of providence, and the meaning of this analysis for normative ethics. The subject matter of this article is part of a wider comparison of distributive justice and providence theory, within which luck egalitarianism affords a very fruitful and highly relevant case study.

This article argues that the religious epistemology of the rabbinic tradition, which preserves and respects multiple perspectives in intellectual debate, is best understood in comparison to the definitions of truth proposed by philosophical pragmatists, in particular William James and W. V. Quine, and in contrast to those of philosophical liberals, in particular J. S. Mill. Both the rabbis and the pragmatists emphasize the harmony that innovation must maintain with extant webs of meaning. Conceptions of objectivity and subjectivity in Jewish medieval (...) rationalism and in early modern mysticism are considered and compared with those of latter-day European and American epistemology. This article makes a case for a fundamentally pluralistic conception of truth and argues that it is exemplified in the social interaction of the talmudic sages. (shrink)

“de-extinction” refers to the process of resurrecting extinct species by genetic methods. This science-fiction-sounding idea is in fact already in early processes of scientific implementation. Although this recent “revival of the dead” raises deep ethical questions, the ethics of de-extinction has barely received philosophical treatment. Rather than seeking a verdict for or against de-extinction, this paper attempts an overview and some novel analyses of the main ethical considerations. Five dimensions of the ethics of de-extinction are explored: (a) the possible contribution (...) of de-extinction to promoting ecological values, (b) the deontological argument that we owe de-extinction to species we rendered extinct, (c) the question of “playing God” through de-extinction, (d) the utilitarian perspective, and (e) the role of aesthetic considerations in the ethics of de-extinction. A general feature arising from the paper’s discussion is that, due to de-extinction’s special character, it repeatedly tests the limits of our ethical notions. (shrink)

The nocebo effect, the mirror-phenomenon to the placebo effect, is when the expectation of a negative outcome precipitates the corresponding symptom or leads to its exacerbation. One of the basic ethical duties in health care is to obtain informed consent from patients before treatment; however, the disclosure of information regarding potential complications or side effects that this involves may precipitate a nocebo effect. While dilemmas between the principles of respect for patient autonomy and of nonmaleficence are recognized in medical ethics, (...) there has not yet been an ethical discussion focused on the potential dilemma raised by the nocebo effect of informed consent. This dilemma is especially pernicious, since it involves a direct causality of harm by the caregiver that is unparalleled by other potential harmful effects of information disclosure. This paper articulates the dilemma of the NEIC and offers a seminal ethical analysis. (shrink)

Mitochondrial bioenergetics plays a key role in multiple basic cellular processes, such as energy production, nucleotide biosynthesis, and iron metabolism. It is an essential system for animals' life and death (apoptosis) and it is required for embryo development. This, in conjunction with its being subjected to adaptive processes in multiple species and its gene products being involved in the formation of reproductive barriers in animals, raises the possibility that mitochondrial bioenergetics could be a candidate genetic mechanism of speciation. Here, we (...) discuss genetic and biochemical evidence for the possible involvement of this unique system, encoded by two genomes (the mitochondrial and nuclear genomes), that differ by an order of magnitude in their mutation rates in processes leading to speciation events.

Distributive justice assumes a morally critical judgment of nature, which typically contradicts providential conceptions. Hence, simple conceptions of divine Providence cannot support distributive justice. This essay analyzes and develops a complex strand of theorizing about Providence within Jewish philosophy that is compatible with distributive justice. According to this conception, the actions of divine Providence express different and mutually exclusive considerations of justice. Therefore, the moral value of outcomes is intransitive between the situations of different people. And while each providential action (...) is justified from an ethical perspective, the total outcome is distinct from God's ultimate desire. Human ethics responds to this disparity by redistribution. This conception of Providence also contributes to the additional issue of intergenerational justice through the concomitant idea of life missions. The classical rendering of missions creates problems, however, for distributive justice. I conclude by formulating a conception of life missions that is compatible with both distributive and intergenerational justice. (shrink)

Ever since the discovery of Marx's Early Writings, most of the literature concerned with Marx's intellectual development has centred around the so-called gap between the 'young' Marx, who was considered to be a humanist thinker, and the 'older' Marx, who was held to be a determinist with little concern for anything outside his narrow theory of historical materialism. Dr Avineri claims that such a gap between the 'young' and 'older' Marx did not exist. He supports his claim by a detailed (...) study of the whole corpus of Marx's writing on social and political thought. (shrink)

This study in English of Hegel's political philosophy presents an overall view of the development of Hegel's political thinking. The author has drawn on Hegel's philosophical works, his political tracts and his personal correspondence. Professor Avineri shows that although Hegel is primarily thought of as a philosopher of the state, he was much concerned with social problems and his concept of the state must be understood in this context.

Metaphor enters contemporary philosophical discussion from a variety of directions. Aside from its obvious importance in poetics, rhetoric, and aesthetics, it also figures in such fields as philosophy of mind (e.g., the question of the metaphorical status of ordinary mental concepts), philosophy of science (e.g, the comparison of metaphors and explanatory models), in epistemology (e.g., analogical reasoning), and in cognitive studies (in, e.g., the theory of concept-formation). This article will concentrate on issues metaphor raises for the philosophy of language, with (...) the understanding that the issues in these various fields cannot be wholly isolated from each other. Metaphor is an issue for the philosophy of language not only for its own sake, as a linguistic phenomenon deserving of analysis and interpretation, but also for the light it sheds on non-figurative language, the domain of the literal which is the normal preoccupation of the philosopher of language. A poor reason for this preoccupation would be the assumption that purely literal language is what most language-use consists in, with metaphor and the like sharing the relative infrequency and marginal status of songs or riddles. This would not be a good reason not only because mere frequency is not a good guide to theoretical importance, but also because it is doubtful that the assumption is even true. In recent years, writers with very different concerns have pointed out that figurative language of one sort or another is a staple of the most. (shrink)
