We review evidence of the psychological and social costs associated with punishing. We propose that these psychological and social costs should be considered (in addition to material costs) when searching for evidence of costly punishment.

We propose that revenge responses are often influenced more by affective reactions than by deliberate decision making as McCullough et al. suggest. We review social psychological evidence suggesting that justice judgments and reactions may be determined more by emotions than by cognitions.

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants’ locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant’s real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by (...) a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

Between 1765 and 1767 Quesnay published Droit naturel and Despotisme de la Chine. I show that these texts are strongly related. I study their various versions and editions, some of which were previously poorly known, and attempt to evaluate their readership. I uncover a lost manuscript and neglected sources of Despotisme de la Chine which help to clarify various points about the text. It is shown that it was finished most probably well before the end of 1766. Its economic contents (...) are briefly described, whether they are similar to other writings of Quesnay or seem to alter his doctrine. It is suggested that Despotisme de la Chine was read by Adam Smith and that he took from it many lines on China found in Wealth of Nations. The paper ends with a proposal of a new edition of Droit naturel and Despotisme de la Chine. (shrink)

Walking is an activity that always unfolds within a certain landscape. Tim Ingold has used the notion of “taskscape” to denote pragmatic uses of terrain. Whilst walking, we come to intersect with a variety of taskscapes. As Julia Tanney has highlighted, formal language can only get us so far when thinking about spontaneous, non-theoretical and non-representational activities. Borrowing Gilbert Ryle’s distinction between “knowing that” and knowing how”, I argue for a concept of walking that does not privilege intentions. When somebody (...) walks, they melt into a taskscape not entirely of their own design. Mind is inherently ecological. It is enacted within a certain ecology, and is actually inseparable from its environment. Mind is the sum of intelligent enactments. According to the position I seek to advance in this article, walking may be approached in an object-oriented manner. Each form of behavior composes an enactment that meshes with a certain ecology, what W. Teed Rockwell has called a “behavioral field.” Mind is the inherently relational enactment of a set of behavioral dispositions which are always already enmeshed within a field. When these dispositions enter what, following Markus Gabriel, may be called “fields of sense”, mind and walking become independent objects in their own right. (shrink)

Islam as both religion and socioeconomic system is based on five main pillars, that is – five basic acts considered mandatory by Muslims, summarized in the hadith of Gabriel. One of them is zakāt (almsgiving), i.e. giving 2.5% of one’s wealth to the poor and needy. In contrary to Christian religion, where question of charity is rather of a voluntary matter, the role of zakāt in Islam is much more rigidly described. Almsgiving is considered as a duty of a pious (...) Muslim towards the poor. Thus in Islamic economy, strongly based on Islam principles given by Allah to Muhammad, zakāt is imposed by law and is not considered a charity but duty rather. The notion of zakāt is mentioned in Qur-an over a 100 times, solely or in conjunction with other commandments. On a basis that zakāt is to be paid as a part of total wealth exceeding given minimum wealth (nisab) it is then justifiable to say that zakāt is principally a tax. A role of this essay is to shed some light on a utilisation and role of zakāt in Islamic economies in socioeconomic context, with an example of Islamic Republic of Pakistan, where in 1980 the Zakāt Ordinance was imposed. The concept of zakāt is present in many Islamic countries, but its nature varies, being dependent from the interpretation of religious law in a given country. Everywhere though, its social role as an important tool maintaining social justice is strongly expressed. Of course zakāt system also has its drawbacks and is subjected to much criticism. The article aims to present both advantages and negative aspects of zakāt. (shrink)

All observers of our legal system recognize that criminal statutes can be complex and obscure. But statutory obscurity often takes a particular form that most observers have overlooked: uncertainty about the identity of the wrong a statute aims to punish. It is not uncommon for parties to disagree about the identity of the underlying wrong even as they agree on the statute's elements. Hidden in plain sight, these unexamined disagreements underlie or exacerbate an assortment of familiar disputes—about venue, vagueness, and (...) mens rea; about DUI and statutory rape; about hate crimes, child pornography, and counterterrorism laws; about proportionality in punishment; and about the proper ambit of the criminal law. Each of these disputes may hinge on deeper disagreements about the identity of the wrong a statute aims to punish, and these deeper disagreements can be surprisingly hard to resolve, fueled as they are by the complex inner structure of our penal laws and the discretionary mechanisms of their administration.

Prominent theories of the criminal law borrow heavily from the two leading theories of temptation—the evaluative conception of temptation, which conceives emotion and desire as essentially involving a kind of evaluation, and the mechanistic conception of temptation, which conceives emotion and desire as essentially involving felt motivation. As I explain, both conceptions of temptation are inconsistent with the possibility of akratic action, that is, action contrary to a person’s conscious better judgment. Both are inconsistent with the possibility of akratic action (...) because both are covertly inconsistent with a two-fold psychological assumption that undergirds common beliefs about human action and lies at the heart of the law of criminal responsibility: that resisting a powerful temptation is extremely difficult yet not ordinarily impossible. I reveal these inconsistencies and offer in place of the leading theories of temptation a theory of affective desire as primitive psychic attraction, an elemental psychological state typically accompanied by evaluation and motivation but not reducible to either one. I then show how this theory of desire is consistent with the possibility of akratic action, with the two-fold psychological assumption at the heart of the law of criminal responsibility, and, in particular, with the defense of provocation.

In a characteristically iconoclastic essay, “Does the State Have a Monopoly to Punish Crime?”, Douglas Husak argues that the state’s moral right to punish crime is all but self-evident while its supposed monopoly on punishment is a fiction. Husak draws this bracing conclusion from a modest, quasi-Lockean premise – that persons and other entities have a right to impose stigmatizing deprivations on those who wrong them. This premise evokes John Locke’s far stronger claim that everyone enjoys a natural right to (...) inflict potentially severe sanctions on any wrongdoer. The quasi-Lockean premise also evokes the familiar idea that all criminal wrongdoing is an attack on the broader community, and that law-breakers consequently owe a debt to society that they can repay through punishment. In this essay, I argue that the inferences Husak draws from the quasi-Lockean premise are unsound, but for reasons that reveal important lessons about the state’s right to punish crime and about the limits of what we can extract from the venerable idea that a central victim of criminal wrongdoing is the community as a whole. In Part II, I argue that the quasi-Lockean premise does not ground the state’s right to punish the kind of wrongs traditionally thought central to the criminal law, namely, wrongs perpetrated on individual human victims. In Part III, I answer Husak’s implicit challenge to describe a kind of stigmatizing deprivation – a kind of punishment – that the state alone has a right to inflict. I suggest that no entity but the state may inflict sanctions that constitute prima facie invasions of moral rights. (shrink)

This article seeks to explore the European debate on commercial nobility at the beginning of the Seven Years War in the light of the intense reform debates over French absolutism in the 1730s and 1740s and Montesquieu's rigid refutation of noble trade in The Spirit of the Laws. In early 1756, Montesquieu's position against noble trade had come under severe attack by Gabriel François Coyer's Noblesse Commerçante. Claiming that the royal absolutist system had transformed the nobles into an idle class (...) without any political, economic, or military function that stood in sharp contrast to the dynamism of modern commercial society, Coyer perceived noble enterprises in maritime, wholesale, and even retail trade as a necessary means to help France compete with commercially more advanced states such as England and Holland. Coyer's pamphlet roused heated controversies in Paris and beyond and soon engaged the leading minds of the time in debates over the actual and desired role of the hereditary aristocracy in monarchies. Coyer's strongest opponents, like the Chevalier d’Arc, vehemently defended Montesquieu's contention that the upkeep of the non-commercial status of the nobility was a political necessity. Yet they, too, conceded that the nobility had to undergo severe reforms not to hamper France's military standing and future economic success. The article finally turns to Johann Heinrich Gottlob von Justi, the most interesting commentator on the debate in Germany, who, by October 1756, had translated Coyer's and d’Arc's texts into German and written an own treatise on the same issue. Justi's pamphlet reveals that his political theory was deeply shaped by the debate and thus disproves the long-held assumption in the literature that German cameralism, with Justi as its main representative, was an allegedly isolated current of thought that neither received significant external influences, nor exerted any considerable impact beyond the boundaries of the Germanic world.

Philosophers have taken little heed of the fact that people often act contrary to their better judgment not because they suffer a volitional infirmity like weakness of will or compulsion but instead because they care too little about what they judge best (they are unconcerned) or they care too much about something else (they are compromised). Unconcerned and compromised action, being varieties of akratic action that do not involve volitional infirmity, are phenomena worth examining not only in their own right (...) but also for what they reveal about the better known varieties of akratic action for which they might easily be mistaken, such as weak-willed action and action (or inaction) that stems from accidie. Unconcern and compromise also are worth examining for what they reveal about a topic beyond philosophical psychology, namely, moral and legal accountability. Forgiveness, resentment, and retributive punishment each may have less to do with what an offender (morally) believes than with what he cares about. (shrink)

In his penetrating book on the criminal culpability of children, Gideon Yaffe advances a novel theory of desert. According to the theory, the punishment you deserve for committing a given crime is the punishment the prospect of which would have led you to deliberate correctly about how to act, had that punishment been presented to you beforehand as an inevitable consequence of your committing the crime. Although fascinating and ambitious, Yaffe’s theory of desert struggles as an account of who deserves (...) what, and it falls short of explaining why and how desert is normatively significant—why and how desert matters.

People ordinarily make sense of their own behavior and that of others by invoking concepts like belief, desire, and intention. Philosophers refer to this network of concepts and related principles as 'folk psychology.' The prevailing view of folk psychology among philosophers of mind and psychologists is that it is a proto-scientific theory whose function is to explain and predict behavior.

In lieu of an abstract, here is a brief excerpt of the content:How Old Are Modern Rights? On the Lockean Roots of Contemporary Human Rights DiscourseS. Adam SeagraveArguing for the proper placement of John Locke’s natural rights theory within intellectual history is a particularly high-stakes enterprise for historians of political thought and political theorists alike. This is due in large part to the fact that, as Brian Tierney notes in his recent study, it is “widely agreed that Locke’s work was (...) an important influence in the formation of modern liberal ideas, including ideas concerning rights.”1 Our understanding of Locke thus contributes to our reflective self-understanding as “modern liberals” (of one stripe or another) to an extent perhaps unequaled by any other thinker so far removed from our own time.As a result of the rare promise of studying Locke’s natural rights theory, there has been no shortage of scholarly attempts to determine its place in intellectual history on the basis of Locke’s own writings and their relation both to preceding and subsequent traditions and modes of thought. Although John Dunn had argued in his influential study that Locke’s political thought was too thoroughly steeped in theology to remain relevant in the contemporary context, this thesis has since been persuasively challenged (albeit in very different ways) by Simmons, Zuckert and Waldron, among others.2 Each of these scholars has contributed to an emerging agreement [End Page 305] that the thread of Locke’s natural rights theory may indeed be carried all the way up to current political and moral debates in some form or another. The precise length of this thread as it extends in the other historical direction has, however, remained a point of heated controversy. The scholarly literature on this issue may be broadly described in terms of a spectrum determined by two opposing emphases in understanding the relation of Locke’s natural rights theory to its medieval predecessors: a continuity emphasis and a discontinuity emphasis.On the discontinuity end of the spectrum stand those such as Michel Villey, Leo Strauss, C. B. Macpherson and, more recently, Michael Zuckert who argue for the existence of some sort of “Copernican moment” separating medieval natural rights theories from their modern counterparts.3 Whether this moment is identified with William of Ockham in the fourteenth century or Hobbes in the seventeenth century, these scholars tend to emphasize the distinctively “modern” character of Lockean natural rights theory and its significant departures from medieval modes of thought. According to many of the advocates of discontinuity, Lockean natural rights are not only “modern” in their political applications but also in their more profound meaning as foundations for morality, and particularly in their newly conceived relation to the concept of natural law.4The continuity end of the spectrum is, perhaps, more variegated, including scholars such as Tuck, Tierney, Tully, Oakley, Nederman, Coleman, and Swanson, among others.5 Despite their many important differences, [End Page 306] these scholars each focus upon the similarities between various elements or strains of medieval thought and modern natural rights theories rather than the differences between them. Insofar as the scholars on this end of the spectrum explicitly consider Locke’s natural rights theory, they tend to emphasize Locke’s intellectual debt to various preceding traditions and thinkers rather than his innovations upon them. Building explicitly upon the work of Tuck, Tierney and Tully, Janet Coleman finds “some extraordinarily Lockean moments” in the medieval thinkers John of Paris and Godefroid of Fontaines, and argues that Locke ought to be understood as contributing to this medieval tradition of thought rather than departing from it.6 Scott Swanson, in turn, builds upon Coleman’s scholarship in carefully connecting medieval understandings of the rights of subsistence and the principle of extreme necessity to Locke’s natural rights theory. Swanson initially goes even further than Coleman in asserting that “all of Locke’s celebrated doctrine is here [in John of Paris’s writings] offered in a nutshell” before concluding on the more moderate note, echoed by Cary Nederman, that Locke’s “application of natural rights of subsistence to politics” may indeed have been something “new under the sun.”7Brian Tierney, who has long been a prominent...

As controversial as Lockean interpretation relating to the ideas of the law of nature and natural rights has always been, few would dispute the inextricable connection between them in the context of John Locke's thought. The historical development of natural rights language out of the natural law tradition is mirrored to a certain extent in the order within and between Locke's own writings. Locke intimates a persuasive account of the concurrent univocal property of God and the human being in the (...) particular human being herself. The particular human being is the property of God and herself in the very same sense of the word "property", i.e. the product of workmanship or labor. Both slavery and suicide fall foul of Locke's doctrine of the law of nature and natural rights: slavery is a violation of self‐ownership, and suicide is as direct a violation of divine ownership as one can imagine.

This paper contends that the natural law theory of Saint Thomas Aquinas has been inappropriately removed from its foundation in the classical philosophical traditions of Cicero and Aristotle. Critics charge that because it refers to the eternal law, and hence divine revelation, St. Thomas’s natural law theory is not “natural.” The author in reply demonstrates the Ciceronian and Aristotelian—and therefore pagan, naturalist—roots of the Thomistic theory. St. Thomas’s discussion of natural law in the Summa mirrors Cicero’s attempted derivation of natural (...) law from “a rational encounter with objective reality.” Further, St. Thomas’s Summa includes demonstrations that God is the Cause of all objective reality. This truth does not however deny the “naturalness” of human rational consideration of reality, but rather shows that humans internally apprehend an external order which owes its reality to the First Cause of all being. Human reason and natural law thereby necessarily involve a participation in the eternal law. The author concludes that attempts to dissociate Thomistic natural law theory from its Ciceronian and Aristotelian roots lessen the force and persuasive power of the former. The proper approach involves, not an abandonment of the traditional theory, but its further development and its application to present issues. (shrink)

This is the first anthology to bring together a selection of the most important contemporary philosophical essays on the nature and moral significance of self-respect. Representing a diversity of views, the essays illustrate the complexity of self-respect and explore its connections to such topics as personhood, dignity, rights, character, autonomy, integrity, identity, shame, justice, oppression and empowerment. The book demonstrates that self-respect is a formidable concern which goes to the very heart of both moral theory and moral life. Contributors: Bernard (...) Boxill, Stephen L.

This commentary highlights the observation that social motivation is usually an imprecisely specified construct. We suggest four social motivation conceptualizations across levels of analysis and explore where the target article situates among these. We then offer theoretical and practical guidance for operationalization and measurement of social motivation to support more comprehensive future research on this complex construct in the autism literature.

In Chapter 1 I discuss the basic problem which made me undertake the issue of human death. That problem was the dualism in the depiction of human nature which has not been fully overcome yet, the dualism which leads to the emergence of new difficulties in contemporary attempts at adequately solving the problem of human death. They include the separation of soul from the body in the moment of death, and the borderline between the moment of death and the moment (...) of resurrection. Chapter 2 is devoted to the presentation of a new anthropological perspective, of an anthropology build “from the bottom up”, that is “from foundations”, and taking into account man’s rooting in the biological environment, and thus also in the genetic heritage taken over from our pre-human ancestors. That anthropology brings new aspects into traditional anthropology by extending it to include new ways of explaining the genesis of the human body and spirit, and new depictions of man’s death. In Chapter 2 I will also present the concept of evolution proposed by P.T. de Chardin, which I appreciate for its comprehensive evolutionary perception of the world. This concept has provoked various responses, but it certainly provides a creative inspiration for further attempts at applying the idea of evolution to various issues. The general framework of the evolutionary model proposed by the French researcher turns out to be useful also when applied to the evolutionary understanding of human death. Chapter 3 contains a discussion of the principal premises of the evolutionary concept of human death taken from analyses carried out by T. Wojciechowski concerning the issue of time, space, and the structure of variable material beings. A being is variable because it has a temporal structure, and the changes that occur are the derivatives of that structure. The temporal structure may be seen as endless, in which a being, even though its existence had a beginning, will exist for ever. Material substance should not be seen statically, but in dynamic and evolutionary terms. In evolution, time becomes a driver of development, an element shaping and directing the evolution of the entire cosmos. Man’s substance has been made capable of two levels of being and acting: the spatial and temporal level, and the endless and immanent level. Together, they form the one essence of man. Thus, the human person is partially immersed in the material cosmos, and partially elevated above it. Chapter 4 presents the evolutionary approach to the moment of man’s death. The views of T. Wojciechowski will be presented in which the moment of death is seen as a moment of transformation and perfection of the structure of the essence of human existence. Furthermore, the issue of the relationship existing, according to T. Wojciechowski, between man’s death and resurrection will be discussed. Understood in evolutionary terms, the moment of death is the time when the structure of human existence is transformed. Death transfers man fully into eternity and enables his life on a higher level of existential being. The element of flesh is retained, but changes its nature. Such view of death allows it to be understood as the moment of resurrection and the culmination of the evolutionary process of life. Death is therefore an “invention” of the evolution and should be seen as a natural and positive phenomenon. At this point, I also propose a solution to the question about reconciliation between temporal and endless existence. In Chapter 5 I take up the issue of consequences flowing from the postulated understanding of human death. They have been pointed to by T. Wojciechowski, but need to be further developed and clarified. He believed two lines in man’s development need to be recognized: that of natural and that of supernatural evolution. Both have the same direction, while occurring on different planes. In each of these lines, death is a natural element of life, pre-planned and, so to say, “encoded” in the cosmic matter. Therefore, the treatment of biological death as the consequence of sin is not only contrary to the evolutionary understanding of life, but in addition artificially combines that which is natural with that which is supernatural. Man’s authentic experience of his own present is a condition of his achieving full existential perfection in the moment of this death. Full engagement in the present is, in a way, a harbinger of the future; thus, the life “here” and “there” may not be inherently inconsistent. In the light of the evolutionary concept, death is not a punishment, but the most positive experience of man’s life in that it enables him to achieve full existential perfection. Chapter 6 is devoted to a substantiation of the possibility of evolutionary transformation of the structure of human existence in the moment of death. An adequate cause needs to be identified which could substantiate that transformation and achievement of perfection. I believe an appropriate substantiation can be found in God’s creative act, interpreted in evolutionary terms. The process of evolution, with its subsequent stages, is only a necessary condition for that “transformation” and “elevation”. The sufficient condition is fulfilled by the continuous creative intervention of God. The concept of God’s creative activity in the moment of man’s death finds its continuation in Chapter 7, where I present a detailed analysis of God’s activity at the time of man’s death. The concept of God’s creative activity extended over the entire process of evolution makes it possible to consider the moment of death as the moment of man’s resurrection. The moment of death is thus a moment of creation in evolutionary terms. Thus, as long as man is related to temporal and spatial elements, his development, or creation, continues. Death is only the completion of the final stage of creation, which may be painful and evoke fear, but in fact should give hope, for it involves resurrection. I also propose that the creative act in the moment of man’s death-resurrection be considered a basic action of God, which explains the manner in which God’s activity is contained within the framework of the creative act, encompassing also the moment of death-resurrection. The final Chapter 8 describes a didactic model illustrating the concept proposed here. I use the analogy of white light dispersion effect in the prism, and compare the incident ray to the creative act, and the dispersed rays going through the prism to the line of man’s natural and supernatural evolution. This model also shows the difference in the perspectives from which the phenomenon of death is seen by God and by man. (shrink)

Research shows that the physician’s personal attributes and social characteristics have a strong association with their end-of-life decision making. Despite efforts to increase patient, family and surrogate input into EOL decision making, research shows the physician’s input to be dominant. Our research finds that physician’s social values, independent of religiosity, have a significant association with physician’s tendency to withhold or withdraw life sustaining, EOL treatments. It is suggested that physicians employ personal social values in their EOL medical coping, because they (...) have to cope with existential dilemmas posed by the mystery of death, and left unresolved by medical decision making mechanisms such as advanced directives and hospital ethics committees.

This article presents the results of an experiment that completely measures the utility function and probability weighting function for different positive and negative monetary outcomes, using a representative sample of N = 1,935 from the general public. The results confirm earlier findings in the lab, suggesting that utility is less pronounced than what is found in classical measurements where expected utility is assumed. Utility for losses is found to be convex, consistent with diminishing sensitivity, and the obtained loss-aversion coefficient of (...) 1.6 is moderate but in agreement with contemporary evidence. The estimated probability weighting functions have an inverse-S shape and they imply pessimism in both domains. These results show that probability weighting is also an important phenomenon in the general population. Women and lower educated individuals are found to be more risk averse, in agreement with common findings. In contrast to previous studies that ascribed gender differences in risk attitudes solely to differences in the degree utility curvature, however, our results show that this finding is primarily driven by loss aversion and, for women, also by a more pessimistic psychological response toward the probability of obtaining the best possible outcome.

The appeal to expert opinion is an argument form that uses the verdict of an expert to support a position or hypothesis. A previous scheme-based treatment of the argument form is formalized within a Bayesian network that is able to capture the critical aspects of the argument form, including the central considerations of the expert's expertise and trustworthiness. We propose this as an appropriate normative framework for the argument form, enabling the development and testing of quantitative predictions as to how (...) people evaluate this argument, suggesting that such an approach might be beneficial to argumentation research generally. We subsequently present two experiments as an example of the potential for future research in this vein, demonstrating that participants' quantitative ratings of the convincingness of a proposition that has been supported with an appeal to expert opinion were broadly consistent with the predictions of the Bayesian model.

Bayesian probability has recently been proposed as a normative theory of argumentation. In this article, we provide a Bayesian formalisation of the ad Hitlerum argument, as a special case of the ad hominem argument. Across three experiments, we demonstrate that people's evaluation of the argument is sensitive to probabilistic factors deemed relevant on a Bayesian formalisation. Moreover, we provide the first parameter-free quantitative evidence in favour of the Bayesian approach to argumentation. Quantitative Bayesian prescriptions were derived from participants' stated subjective (...) probabilities (Experiments 1 and 2), as well as from frequency information explicitly provided in the experiment (Experiment 3). Participants' stated evaluations of the convincingness of the argument were well matched to these prescriptions. (shrink)
