The logical structure of Quantum Mechanics (QM) and its relation to other fundamental principles of Nature has been for decades a subject of intensive research. In particular, the question whether the dynamical axiom of QM can be derived from other principles has been often considered. In this contribution, we show that unitary evolutions arise as a consequences of demanding preservation of entropy in the evolution of a single pure quantum system, and preservation of entanglement in the evolution of composite quantum (...) systems. 6.

We discuss the role of the notion of information in the description of physical reality. We consider theories for which dynamics is linear with respect to stochastic mixing. We point out that the no-cloning and no-deleting principles emerge in any such theory, if law of conservation of information is valid, and two copies contain more information than one copy. We then describe the quantum case from this point of view.

Convolutional neural networks (CNNs) are increasingly widely used in psychology and neuroscience to predict how human minds and brains respond to visual images. Typically, CNNs represent these images using thousands of features that are learned through extensive training on image datasets. This raises a question: How many of these features are really needed to model human behavior? Here, we attempt to estimate the number of dimensions in CNN representations that are required to capture human psychological representations in two ways: (1) (...) directly, using human similarity judgments and (2) indirectly, in the context of categorization. In both cases, we find that low-dimensional projections of CNN representations are sufficient to predict human behavior. We show that these low-dimensional representations can be easily interpreted, providing further insight into how people represent visual information. A series of control studies indicate that these findings are not due to the size of the dataset we used and may be due to a high level of redundancy in the features appearing in CNN representations.

The classical theory of rational choice is built on several important internal consistency conditions. In recent years, the reasonableness of those internal consistency conditions has been questioned and criticized, and several responses to accommodate such criticisms have been proposed in the literature. This paper develops a general framework to accommodate the issues raised by the criticisms of classical rational choice theory, and examines the broad impact of these criticisms from both normative and positive points of view.

Absent mistake or misrepresentation, most scholars assume that parties who agree to contract do so voluntarily. Scholars tend further to regard that choice as an important exercise in moral agency. Hanoch Dagan and Michael Heller are right to question the quality of our choices. Where the fundamental contours of the transaction are legally determined, parties have little opportunity to exercise autonomous choice over the terms on which they deal with others. To the extent that our choices in contract do not (...) reflect our individual moral constitutions — our values, virtues, vices, the set of reasons we reject and the set of reasons we endorse — we are not justified in regulating contracts reluctantly. Contracts are entitled to the privilege of liberal regulatory deference only to the extent that they are the work product of individual autonomy. The assumption that contract is voluntary does enormous work in most normative theories of contract. This Article takes still more seriously the obstacles to autonomous choice that contracting parties face. The most important constraints are not in contract law itself but in the material and moral imperatives that dictate parties’ contracting preferences. Many contracts are driven by circumstantial considerations or actual background obligations. While these contracts are not wholly lacking in the element of voluntariness, we should distinguish them from those choices — and those contracts — which more fully realize our potential to self-consciously author our relations with others. Autonomous choice in contract requires more than Dagan and Heller imply, and it is likely beyond the power of contract law standing alone to deliver it. (shrink)

Arguments for the expansion of formal schooling have long focused on individual outcomes from schooling, including increasing income, reducing poverty, delaying marriage, and improving health, particularly for girls and women. For nearly three decades now, global education agendas have supported girls’ education in an effort to achieve these outcomes. A large body of research analyzes girls’ individual empowerment from schooling, but less attention is given to how schooling is creating change in families and communities, particularly for lowered-caste girls in India. (...) This article places longitudinal data from a three-year qualitative interview study of schoolgirls in Rajasthan alongside qualitative life-history interviews of girls who completed secondary school in Uttarakhand to understand how schooling affects social changes for lower castes. The analysis, using an intersectional and relational approach, illustrates how girls’ schooling shifts kin and caste relations connected to marriage and work but in ways that do not transform the stickiness of caste and gender norms. We argue that educational policies and programs must attend to the ways in which caste is implicated in achieving outcomes of delayed marriage and formal employment for lowered-caste girls in Indian communities if schooling is to create positive social change.

This paper considers the question of virtues appropriate to a corporate actor's moral character. A model of corporate appetites is developed by analogy with animal appetities; and the pursuit of initially virtuous corporate tendencies to an extreme degree is shown to be morally perilous. The author thus refutes a previous argument which suggested that (1) corporate virtues, unlike human virtues, need not be located on an Aristotelian mean between opposite undesirable extremes because (2) corporations do not have appetites; and (3) (...) corporate virtues must serve the end of sustainable profit. If these disanalogies between corporate and human virtue no longer hold, then the stage is set for us to formulate a more adequate model of good corporate character that would encompass other-regarding virtues.

The premise of contract law is that the redistribution of entitlements that results from contract is justified by the process of agreement. But theories of contract differ importantly on how and when voluntary exchange justifies a resorting of entitlements. Pure theories regard the principles of contract as essentially derivative from some aspect of the principle of autonomy; contracting parties’ intent to assume legal obligation is in principle necessary and sufficient for its enforcement. Perfect theories do not view contract as self-justifying (...) but regard the process of agreement as reliable evidence that contracts are welfare-improving. This article demonstrates the limitations of pure and perfect views. It favours instead imperfect theories of contract, which would have judges self-consciously pursue the normative ends of contract law as they apply context-sensitive rules. (shrink)

There is something missing in existing discussions of domination. While republican theory, antisubordination theory, and critical legal theory each have contributed significantly to our understanding of domination, their focus on structural relationships and group subordination can leave out of focus the individual wrongs that make up domination, each of which is an unjustified exercise of power by one person over another. Private law (supported by private law theory) plays an important role in filling out our pictures of domination and the (...) role of the state in limiting it. Private law allows us to recognize domination in wrongs by one person against another, and it has the potential to articulate the state-enforced boundaries on domination as well as a framework for thinking through inevitable compromises between the aspiration to nondomination and other basic interests of a liberal state. We can understand employment law as continuous with private law, that is, attempting to vindicate a nondomination principle in the context of employment by regulating specific acts of employers. Alternatively, we might understand employment relationships to define group membership, commonly recognized along class lines. In that case, employment law is not about individual nondomination but about mitigating class subordination. It might do this in service of the antisubordination principle, or in order to ensure that employees are capable and ready to exercise the responsibilities of democratic citizenship. While these various purposes largely coincide, there are points of normative divergence which sometimes require that we prioritize one or other function of employment law over the others. (shrink)

Extending a nascent line of Asian philosophical research in music education, we mine Indian philosophies of music and education. Three key questions guide our project: What are Vedic philosophies of music? What are Vedic philosophies of education? Taken together, what insights can we draw for contemporary music education writ large? To address our questions, we analyze key passages from the Upanishads and synthesize ideas from these texts. A quartet of inter-related ideas emerge from our analysis: the guru, the shishya, vidya, (...) and moksha. In brief, the guru (teacher) is revered as one would god, for it is the teacher who leads the shishya (student) toward vidya (knowledge) and through that toward moksha (liberation of the soul), which can also be attained via making music, such as the singing of Om (the absolute sound). In addition to proffering insights for contemporary music education, particularly in terms of how the ancient Vedic guru-shishya parampara adds nuance to contemporary discussions on the master-apprentice model of music education, we imagine how music education philosophy might look like if it were to be sung.

This article suggests that criminality in leaders might best be understood by ethicists as a matter of degree. Leaders may take without legitimate claim a variety of tangible or intangible goods including ideas and personal health. The extent to which any such act should be disfavoured is subject to debate. Moreover, both theft and control may be understood as continuous phenomena. Kleptocratic regimes within workplace or family may foster in people a habit of accepting similar treatment from economic and political (...) leaders at all levels. Forms of governance may be arranged on a continuum from those that serve to those that exploit their subjects. Responses to kleptocratic regimes range from acceptance through unconscious and conscious resistance to violent revolt. (shrink)

Retribution? Restitution? Reconciliation? “Justice” comes in many forms as witnessed by the spike in war crimes tribunals, Truth & Reconciliation Commissions, hybrid tribunals and genocide trials. Which, if any form is appropriate should be influenced by the culture of the people affected. It took Cambodia over three decades to finally address the ghosts of its Khmer Rouge past with the creation of a hybrid Khmer Rouge Tribunal. But how meaningful is justice to the majority of survivors of the Khmer Rouge (...) auto-genocide when only a handful of top officials are tried? Further, given the persistent abuse of political and economic rights in post-conflict Cambodia, we are skeptical that justice or reconciliation is presently possible. (shrink)

The months preceding and following the inauguration of Donald Trump as the 45th President of the United States have incited furious debate about the authenticity of media discourse in the shaping of reality, including in particular the reporting of refugees from predominantly Muslim regions and their resettlement in Western nations. Much of this debate is rooted in how opposing discourse clans, such as liberal and conservative ideologies, construct a narrative of nationhood around contested views of refugees. Examining mainstream and alternative (...) media from a critical discourse analytic perspective, the article uncovers how two key narratives about the Syrian refugee crisis emerge when the media attempt to orient their respective audiences to government policy through the discursive formation of the American Dream. Drawing on aspects of historicity, linguistic and semiotic action, and social impact, the analysis of the data reveals a discursive fracas between a humanistic perspective on the crisis that exploits a banal understanding of the American Dream and a more dichotomous narrative that homogenises refugees as a threat to the American way of life. These observations add to the growing body of literature that questions the ways in which the media discursively shapes, and is shaped by, political ideologies. (shrink)

This paper takes the position that interpretations of legal discourse are invariably taken in the context of socio-pragmatic realities to which a particular instance of discourse applies. What makes this process even more complicated is the fact that social realities themselves are often negotiated within the mould of one’s subjective conceptualisations of reality. Institutions and organisations, including people in power, often represent socio-political realities from an ideologically fuelled perspective, engendering many ‘illusory’ categories often a result of contested versions of reality. (...) To substantiate this view, we discuss interpretations of a number of interesting contemporary and controversial laws, including America’s Patriot Act and Hong Kong’s proposed Article 23 of the Basic Law. Both laws can be seen as illustrative of the definitional conflict that abstract concepts such as democracy and human rights are subjected to in their own specific socio-political contexts. While America crowns itself with democracy and Hong Kong struggles to achieve it in effective synthesis with its unique political arrangement, the laws produced by both contrasting political systems are unexpectedly similar, aiming for the moderation of basic rights. The actions of both governments set against their beliefs and discourses, and furthermore set against one another and other media voices, particularly those of non-governmental organisations, political activists, and other socio-political groups, demonstrate contestation of realities, giving rise to ‘discursive illusions’, which seem to be interpreted not so much on the basis of their linguistic construction but more on the basis of socio-pragmatic factors, such as trust, belief, transparency, control and power.

Colloquially, episodic memory is described as “the memory of personally experienced events”. Even though episodic memory has been studied in psychology and neuroscience for about six decades, there is still great uncertainty as to what episodic memory is. Here we ask how episodic memory should be characterized in order to be validated as a natural kind. We propose to conceive of episodic memory as a knowledge-like state that is identified with an experientially based mnemonic representation of an episode that allows (...) for a mnemonic simulation thereof. We call our analysis the Sequence Analysis of Episodic Memory since episodes will be analyzed in terms of sequences of events. Our philosophical analysis of episodic memory is driven and supported by experimental results from psychology and neuroscience. We discuss selected experimental results that provide exemplary evidence for uniform causal mechanisms underlying the properties of episodic memory and argue that episodic memory is a natural kind. The argumentation proceeds along three cornerstones: First, psychological evidence suggests that a violation of any of the proposed conditions for episodic memory amounts to a deficiency of episodic memory and no form of memory or cognitive process but episodic memory fulfills them. Second, empirical results support a claim that the principal anatomical substrate of episodic memory is the hippocampus. Finally, we can pin down causal mechanisms onto neural activities in the hippocampus to explain the psychological states and processes constituting episodic memory. (shrink)

Declaring that the universe was created in a certain order, Almighty Allah said, "Do not make mischief on earth after it has been brought into order." With this statement she made, she warned humanity not to disturb the established order. Natural disasters such as epidemics, earthquakes, floods and landslides that we face in the 21st century make it necessary to draw attention to the actions of people once again. Human beings, who interfere with nature irresponsibly, disrupt the balances in the (...) universe, and these disturbed balances return to humanity as a calamity over time. Almighty Allah knows in many verses that these calamities are the result of people's own deeds. To this situation; He emphasizes with the expressions “bimâ kesebû, “bimâ kesebet eydinnâs”, “febimâ kesebet eydiküm”, “bimâ kaddemet eydîhim”,“bimâ zalemû”. It is understood from these expressions that a significant part of the calamities are caused by human error, negligence and unjust interventions. While troubles and calamities mean punishment/retribution for some people, the same event can be a test or a lesson for other people. In this context, it is stated in the Qur'an that many troubles and calamities that have been experienced in the past, such as Noah's Flood, have been made a lesson for all humanity as follows: “As for the people of Noah, We drowned them because they denied their prophet, and made them a sign for the people. We have prepared a painful chastisement for the wrongdoers.” As can be seen, while it is stated in the verse that the cause of the torment is people's denial of the prophets, on the other hand, it is emphasized that this event is a lesson for all humanity. However, it is stated in the next verse that those who do not take lessons from these events and warnings and insist on doing what their souls want deserve punishment. However, the words of the Prophet also guide us regarding the epidemic that befell us and our attitude towards troubles. He (sas) prayed to Allah so that his ummah would not be destroyed altogether. He said that "taun" is a kind of punishment that Allah punishes some people, but it is a mercy for believers. In line with the verses we have mentioned, although most of the calamities are the result of human actions, it is out of the question to call every calamity a divine punishment. Because the prophets suffered the greatest of troubles. This topic is too broad to be tackled from a single point of view. The individual, social, human, divine and test dimensions of the subject should be evaluated as a whole. Therefore, such a sensitive issue that needs to be evaluated from multiple perspectives; Bringing only a part of it to the fore as "trouble equals divine punishment" would be to deviate the subject from its target. In this study, within the framework of the scriptures, the individual, social and divine dimensions of troubles and calamities, these calamities may have spiritual causes as well as material reasons; it will be examined that every calamity is not caused by the mistakes of people, but some of them are caused by what people do. In addition, it will be pointed out that troubles and calamities should be evaluated in a multi-dimensional way within the framework of main elements such as faith, test, hope, precaution, trust, patience, prayer and divine providence.

This book develops some of the most important themes of Sen's works over the last decade. He argues in a rich and subtle approach that we should be concerned with people's capabilities rather than their resources or welfare.

Commodities and Capabilities presents a set of inter-related theses concerning the foundations of welfare economics, and in particular about the assessment of personal well-being and advantage. The argument presented focuses on the capability to function, i.e. what a person can do or can be, questioning in the process the more standard emphasis on opulence or on utility. In fact, a person's motivation behind choice is treated here as a parametric variable which may or may not coincide with the pursuit of (...) self-interest. Given the large number of practical problems arising from the roles and limitations of different concepts of interest and the judgement of advantage and well-being, this scholarly investigation is both of theoretical interest and practical import.

This book discusses the study and analysis of the physical aspects of social systems and models, inspired by the analogy with familiar models of physical systems and possible applications of statistical physics tools. Unlike the traditional analysis of the physics of macroscopic many-body or condensed matter systems, which is now an established and mature subject, the upsurge in the physical analysis and modelling of social systems, which are clearly many-body dynamical systems, is a recent phenomenon. Though the major developments in (...) sociophysics have taken place only recently, the earliest attempts of proposing "Social Physics" as a discipline are more than one and a half centuries old. Various developments in the mainstream physics of condensed matter systems have inspired and induced the recent growth of sociophysical analysis and models. In spite of the tremendous efforts of many scientists in recent years, the subject is still in its infancy and major challenges are yet to be taken up. An introduction to these challenges is the main motivation for this book. (shrink)
