This article introduces a simple and effective new algorithm for image encryption using a chaotic system which is based on the magic squares. This novel 3D chaotic system is invoked to generate a random key to encrypt any color image. A number of chaotic keys equal to the size of the image are generated by this chaotic system and arranged into a matrix then divided into non-overlapped submatrices. The image to be encrypted is also divided into sub-images, and each sub-image (...) is multiplied by a magic matrix to produce another set of matrices. The XOR operation is then used on the resultant two sets of matrices to produce the encrypted image. The strength of the encryption method is tested in two folds. The first fold is the security analysis which includes key space analysis and sensitivity analysis. In the second fold, statistical analysis was performed, which includes the correlation coefficients, information entropy, the histogram, and analysis of differential attacks. Finally, the time of encryption and decryption was computed and show very good results. (shrink)

I Can we make promises to ourselves? This is a question that has not received much consideration in the large body of philosophical work on promising. And in what commentary there is, the answer is uniformly negative. I think this negativity is a mistake, and that the conventional view that we can't make reflexive promises is wrong. I also think that this has some important implications for promissory theory in general. In what follows, I will attempt to argue for the (...) first of these two claims, and to briefly outline my reasons for the second. (shrink)

This paper examines the moral case for a right to religious accommodation, which requires that religious conduct be free of any serious burdens placed on it by the state. Two different types of normative argument for this right are outlined and rejected. The first appeals to religion as a ‘basic good’, and the second to religion as an ‘intense preference’. In place of these, I suggest that a third type of argument has greater prospects of success. Religious accommodation is justified (...) on the grounds that religious conduct is a ‘derivative good’— that is, it derives its value from its being necessary for something else, namely, the integrity of the religious person.

This article examines how a just society must address the needs of its imprudent members. I defend compulsory insurance as an answer to this question. It has been assumed that compulsory insurance can only be justified on paternalistic grounds. I argue that this assumption is incorrect, and defend non-paternalistic compulsory insurance. To display the merits of NPCI, I identify a trilemma that arises for views about how to address the needs of the imprudent, including libertarian and so-called ‘ luck -egalitarian’ (...) views. I then suggest that NPCI enables us to escape the trilemma. (shrink)

This article develops the argument that the state must provide parental subsidies if, and to the extent that, individuals would, under certain specified hypothetical conditions, purchase ‘insurance cover’ that would provide the funds they need for adequate childrearing. I argue that most citizens would sign up to an insurance scheme, in which they receive a guarantee of a means-tested parental subsidy in return for an obligation to pay a progressive income tax to fund the scheme. This argument from insurance bolsters (...) the weaker case that proponents of parental subsidies might offer were they to rely exclusively on arguments from fair play and efficiency. (shrink)

This paper provides a critical examination of the strongest defenses of the pure lifetime view, according to which justice requires taking only people's whole lives as relevant when assessing and establishing their distributive entitlements and obligations. The paper proposes that we reject a pure lifetime view and replace it with an alternative view, on which some time-specific considerations--that is to say, considerations about how people fare at specific points in time--have nonderivative weight in determining what our obligations are to them.

Permaculture design seeks to create sustainable communities, and over time has established itself as a transnational community of practice. Based on original interviews with permaculture practitioners from around the world, and drawing on the three core elements of communities of practice – shared domain, communality and shared practices – as our analytical framework, this paper makes three arguments. First, the shared domain of permaculture as a body of knowledge, a system of ethics and set of practical design principles creates an (...) overarching teleological regime that anchors the globally dispersed collective activities of permaculture practitioners. Second, communality in the international permaculture community is centred around the permaculture design course, national and international permaculture convergences, and organisations and demonstration sites that act as hubs for practitioner interaction, linked across national borders by social media networks. Third, shared practices in the permaculture community centre on relationship-building and local-level community organisation. (shrink)

This paper addresses the questions of how we should interpret the autonomy of children and of how we should identify the treatment their autonomy demands of others. In examining this question, the paper casts doubt on two views of the nature and relevance of the autonomy of children. It criticises Joel Feinberg’s well-known view that the autonomy claims of children are reducible to the autonomy claims of the future adults the children will become. It also raises objections to Matthew Clayton’s (...) proposal that the treatment of children should be constrained not only by their future autonomy, but also by a particular component of their autonomy, namely, their independence. We believe Clayton’s proposal has the merit that it does not, unlike Feinberg’s proposal, restrict the basis of the autonomy-claims of children purely to the future autonomy they will enjoy as adults. Nevertheless, we do not believe that the concern with independence adequately captures the autonomy claims of children. After considering these alternative views, the paper proposes that the autonomy claims of children are in fact routed in their evolving capacities for autonomous decision-making. We argue that this proposal both fits with some common-sense ideas about how children ought to be treated, and upholds Clayton's radical proposal that parents should not enrol their children into their comprehensive views about the good life, including their religious views.

This book provides a clear and nuanced appraisal of Hegel's treatment of Africa, India, and Islam, and of the implications of this treatment for postcolonial and global studies. Analyzing Hegel's master-slave dialectic and his views on Africa, India, and Islam, it situates these views not only within Hegel's historical scheme but also within a broader European philosophical context and the debates they have provoked within Hegel scholarship. Each chapter explores various in depth readings of Hegel by postcolonial critics, investigating both (...) the Eurocentric and potentially global nature of his dialectic. Ultimately, the book shows both where of this profoundly influential thinker archetypally embodies certain Eurocentric traits that have characterized modernity and how, ironically, he himself gives us the tools for working towards a more global vision. Offering a concise introduction not only to an important dimension of Hegel's thought - his orientation towards "empire" - but also to the various issues raised by postcolonial theory and global studies, this book will be of use to philosophers as well as advanced students of literary and cultural theory alike.

Policies that shift the costs of higher education from the taxpayer to the university student or graduate are increasingly popular, yet they have not been subjected to a thorough normative analysis. This paper provides a critical survey of the standard arguments that have been used in the public debate on higher education funding. These arguments are found to be wanting. In their place, the paper offers a more systematic approach for dealing with the normative issues raised by the funding of (...) higher education. This approach is drawn from the political theory of John Rawls, whose view seeks to reconcile the values of equality, efficiency, and liberty. I show that, contrary to what we may think at first, an egalitarian approach like Rawls’ does not in principle rule out policies that shift the funding burden from taxpayers to students or graduates. Which funding policy that approach selects as most fair will instead depend on the likely impact on the lifetime income prospects of the worst-off group in society, and this is a question which will need to be settled by empirical evidence.

Philosophers often understand environmental sustainability as a duty of distributive justice between the generations of the earth. Since every generation is equally entitled to the bounty of the natural environment (the thinking goes) every generation should have a fair share of that bounty. But since generations precede each other in time, it is the duty of earlier generations to ensure that later generations receive their fair share. Acting sustainably is the way of meeting this duty, since sustainable practices are those (...) that (ideally) preserve the environment for the future. But what is a ‘fair’ share of something as complex, varied and dynamic as ‘the environment'? How are we to value nature for the purposes of measuring ‘shares’ of it? I think the answer to these questions lies in the difference between sharing something by parts, like a pie, and sharing something by turns, like a bicycle. The generations share the earth by turns, not by parts, and so questions about fairness of shares are questions about turns, not parts. We need to ask what constitutes a ‘fair turn’ with the earth, and for that question we don't necessarily need to be able to commensurate the various parts of nature, just as we don't need to know the relative value of the parts of a bicycle to say what constitutes a fair turn with it.

In this paper we ask whether liberal egalitarians can endorse workfare policies that require that welfare recipients should work in return for their welfare benefits. In particular, we focus on the fairness-based case for workfare, which holds that people should be responsible for their own welfare since they would otherwise impose unfair costs on others. Two versions of the fairness-based case are considered: The first defends workfare on the grounds that it would form part of an unemployment insurance scheme that (...) individuals would endorse under certain hypothetical conditions that are salient for the purposes of determining just public policy. The second appeals to the notion of reciprocity in order to justify the requirement that people work for their benefits. We cast doubt on both of these arguments for workfare. Neither argument shows that the unconditional provision of welfare benefits is unjust; hence, the fairness case for workfare is inconclusive. (shrink)

Rafey Habib's book offers a comprehensive study of Eliot's philosophical writings and attempts to assess their impact on both his early poetry through 'The Waste Land' and the central concepts of his literary criticsm. Habib presents the first scholalrly analysis of Eliot's difficult unpublished papers on Kant and Bergson and establishes the nature of Eliot's connections with major figures in the Western philosophical tradition, including Plato, Aristotle, Locke, Hume, Hegel, Schopenhauer, Nietzsche, Bradley and Russell. The Early T. S. (...) Eliot and Western Philosophy attempts to unravel the complex notions of irony underlying Eliot's poetry, arguing that these originate in his philosophical thinking and achieve persistent expression in his early aesthetics. This book offers close readings of Eliot's major poems and critical essays, shedding valuable light on his views on language, tradition, impersonality and emotion, and situating these in a broad aesthetic and philosophical context.

This article reconstructs the main arguments in John Locke’s first political writings, the highly rhetorical, and often obscure, Two Tracts on Government . The Tracts support the government’s right to impose religious ceremonies on its people, an astonishing fact given Locke’s famous defense of toleration in his later works. The reconstruction of the Tracts developed here allows us to see that rather than a pessimistic view of the prospects for peace under religious diversity, what mainly animates the young Locke is (...) a desire to defend the rule of law against an anarchical conception of religious freedom. The article also argues that the evolution of Locke’s thinking on religious freedom was in large part governed by Locke’s attempt to interpret religious freedom in a way that avoids its having anarchical implications.

Racial profiling appears to be morally more troubling when the racial group that is the object of the profile suffers from background injustice. This article examines two accounts of this intuition. The responsibility-based account maintains that racial profiling is morally more problematic if the higher offender rate within the profiled group is the result of social injustices for which other groups in society are responsible. The expressive harm based account maintains that racial profiling is more problematic if it makes background (...) injustice vivid and thereby causes the profiled to feel resentment. I raise problems with both accounts and suggest a third account. On the humiliation-based account, individuals who are subjected to racial profiling in a context of background injustice are placed in a situation in which they cannot prevent appearing to onlookers in a demeaning way.

With a wealth of detail, this book traces the acceptance and rejection of Soren Kierkegaard's thought in the late nineteenth and early twentieth centuries. Engaging the reader with biographical sketches of Kierkegaard and his contemporaries, Habib Malik presents a fascinating historical narrative of the early reception of Kierkegaard's thought. At the center of this story is an exploration of how Kierkegaard's ideas moved from the relative obscurity of Copenhagen at the time of his death in 1855 to the center (...) of European intellectual culture in the mid-1920s. Receiving Soren Kierkegaard is the first serious attempt to chronicle the early "lost years" of Kierkegaard's intellectual legacy. It analyzes Kierkegaard's profound impact on the lives and thought of such figures as Orsted, Ibsen, Jacobsen, Brandes, Nietzsche, Dilthey, Unamuno, Joyce, Rilke, Kafka, Lukacs, and Kassner.

Do the various forms of literary theory - deconstruction, Marxism, new historicism, feminism, post-colonialism, and cultural/digital studies - have anything in common? If so, what are the fundamental principles of theory? What is its ideological orientation? Can it still be of use to us in understanding basic intellectual and ethical dilemmas of our time? These questions continue to perplex both students and teachers of literary theory. Habib finds the answers in theory's largely unacknowledged roots in the thought of German (...) philosopher Hegel. Hegel's insights continue to frame the very terms of theory to this day. Habib explains Hegel's complex ideas and how they have percolated through the intellectual history of the last century. This book will interest teachers and students of literature, literary theory and the history of ideas, illuminating how our modern world came into being, and how we can better understand the salient issues of our own time.

While there has been much discussion of how the scientific establishment’s culture can engender research misconduct and scientific irreproducibility, this has been discussed much less frequently with respect to the medical profession. Here the authors posit that a lack of self-criticism, an encouragement of novel scientific research generated by the recruitment policies of the UK Royal Training Colleges along with insufficient training in the sciences are core reasons as to why research misconduct and dishonesty prevail within the medical community. Furthermore, (...) the UK General Medical Council’s own data demonstrates a historic inattentiveness to the ease with which doctors can engage in research misconduct. Suggestions are made as to how these issues can be investigated and alternative incentives for career advancement are adumbrated. (shrink)

How, exactly, must we strike the balance between security and equality? Must we insist, out of respect for the equality of persons, that the police refrain from using ethnic profiling and opt for some other strategy in their pursuit of terrorists, or must we allow the police to continue with this policy, which seems to sacrifice equality for the sake of security? This paper assesses the ethical status of ethnic profiling from the perspective of the ideal of equality. The paper (...) shows how the ethical status of ethnic profiling changes depending on how exactly we specify the egalitarian ideal. Furthermore, it argues that on a plausible interpretation of the ideal of equality, ethnic profiling is not in principle objectionable. (shrink)

While the current Internet has brought comforts in our lives, the future of the Internet that is the Internet of Things promises to make our daily living even much easier and convenient. The IoT presents a concept of smart world around us, where things are trying to assist and benefit people. Patient monitoring outside the hospital environment is one case for the IoT in healthcare. The healthcare system can get many benefits from the IoT such as patient monitoring with chronic (...) disease, monitoring of elderly people, and monitoring of athletes fitness. However, the comfort may bring along some worries in the form of people’s concerns such as right or wrong actions by things, unauthorised tracking, illegal monitoring, trust relationship, safety, and security. This paper presents the ethical implications of the IoT in eHealth on people and society, and more specifically discusses the ethical issues that may arise due to distinguishing characteristics of the IoT.

According to the most influential contemporary reading of John Locke's Letter Concerning Toleration, his main argument against religious persecution is unsuccessful. That argument holds that coercion is ineffective as a means of instilling religious beliefs in its victims. I propose a different reading of the Letter. Locke's main consideration against persecution is not the unsuccessful belief-based argument just outlined, but what I call the sincerity argument. He believes that religious coercion is irrational because it is ineffective as a means of (...) inculcating the right intentions in people. Once this alternative argument is placed at its centre, the Letter is seen to be a more fertile source of political argument than is suggested by alternative readings. In particular, the sincerity argument gives us a powerful reason for rejecting state moral paternalism, the doctrine that the state may use coercion to make people morally virtuous. If moral virtue depends upon people having the right intentions, and if coercion is ineffective as a means of instilling the right intentions in people, then state moral paternalism is ineffective and hence irrational.

This is a study of Master Ramchandra, a nineteenth-century Indian mathematician, social commentator and Urdu journalist. The contradictions manifest in his projects, it is contended, were actually the products of the contradictions manifest in the political and ideological thinking of the period. One encounters in his writings a dominant critique of the prevalent religious, social and educational systems and also a call for social transformation, wherein scientific rationality and realism came to play an important role. Ramchandra's understanding is quite close (...) to that of the Comtean positivists. An attempt is made here to locate this emerging scientism within the context of nineteenth-century colonial politics. (shrink)

The strengthening of intolerance and religious movements of various mass organisations after the 1998 reform in Indonesia caused social friction. The Ministry of Religious offers religious moderation as an essential aspect of the plurality of spiritual life. What is the concept and practice of religious moderation for each mass organisation? This research is qualitatively descriptive, with a sociological approach to religion. The concept of religious moderation of mass organisastions is different; they claim to understand the principle of wasathiyyah so that (...) it becomes a view of life that accepts religious differences outside themselves. Religious moderation is in the form of religious views, attitudes, and behaviours that balance the interests of life, the world and the hereafter, personal with the public, and others. There are four indicators of religious moderation: nationalism, tolerance, non-violence, and local cultural accommodation. MTA understands religious moderation based on two principles: not being self-righteous, and do not blame other groups; FPI departs from its vision, religious moderation over the spirit of ‘amar ma’ruf nahi munkar; LUIS sees religious moderation based on the principles of Islam as a religion of rahmatan lil’alamin, the implications for the balance of the relationship between habl min Allah; habl min an-nass and habl min al-’alam; and MMI understands religious moderation based on three aspects: Islam is a religion that is syumul and rahmatan li’alamin; religious moderation related to sharia enforcement; and religious moderation means that fulfillment of maqashid asy-syariah includes ushul al-khamsah: hifdz al-din, hifdz an-nafs, hifdz al-mal, hifdz al-’aql, and hifdz an-nasb.

Hegel's philosophy is central to the very foundations of modern Western thought. His speculative system brought into confluence two movements—the Enlightenment and Romanticism—which have shaped modernity, and it gave rise to many streams of thought, including Marxism, Anglo-American Idealism, and various forms of historicism. Equally, his thought provoked widespread and pervasive reactions such as those embodied in positivism, realism, and existentialism.One of the more recent series of reactions—particularly within the areas of literary and cultural theory—has been against Hegel's Eurocentrism, which (...) has been examined in its treatment of Africa and the "Orient" in general.

One of the most distinctive features of Ronald Dworkin’s egalitarian theory is its commitment to holding individuals responsible for the costs to others of their ambitions. This commitment has received much criticism. Drawing on Dworkin’s latest statement of his position in Justice for Hedgehogs (2011), we suggest that it seems to be in tension with another crucial element of Dworkin’s own theory, namely, its endorsement of the importance of people leading authentic lives – lives that reflect their own values. We (...) examine this tension between responsibility and authenticity, and some strategies Dworkin does and could deploy to defuse it, which we think are unsuccessful. We then propose a solution for reconciling the demands of responsibility and authenticity, which is, so we claim, friendly to Dworkin’s fundamental commitments but which leads to a revisionist interpretation of the demands of equality of resources.

According to Tocqueville, the freedom of the press, which he treats as an extension of the freedom of speech, is a primary constituent element of liberty. Tocqueville treats the freedom of the press in relation to and as an extension of the right to assemble and govern one’s own affairs, both of which he argues are essential to preserving liberty in a free society. Although scholars acknowledge the importance of civil associations to liberty in Tocqueville’s political thought, they routinely ignore (...) the importance he places on the freedom of the press and speech. His reflections on the importance of the free press and speech may help to shed light on the dangers of recent attempts to censor the press and speech. (shrink)

In this comment, I reply to two objections John Tate raises against my discussion of the trajectory of Locke's ideas on toleration Tate maintains that I misunderstand the role of natural law and civil peace in Locke's thought. I defend my interpretation of the role of natural law and show that Tate is mistaken in his claim that Locke's concern to preserve civil peace conflicted with his separate concern to protect individual rights.

Politics, Philosophy & Economics, Ahead of Print. When skilled individuals emigrate from developing states to developed states, they leave a burdened state behind and bring their valuable human capital to a state that enjoys vast advantages by comparison. Most of the normative debate to date on this so-called ‘brain drain’ has focused on the duties that skilled emigrants owe to their home state after they emigrate. This article shifts the focus to the question of whether their host state acquires special (...) duties toward their home state and argues for an affirmative answer to that question. After identifying the conditions under which ‘exploitative free-riding’ can occur, the article shows that the brain drain is a case of exploitation that gives rise to special duties of compensation for developed host states.
