We consider three accepted truths about iris biometrics, involving pupil dilation, contact lenses and template aging. We also consider a relatively ignored issue that may arise in system interoperability. Experimental results from our laboratory demonstrate that the three accepted truths are not entirely true, and also that interoperability can involve subtle performance degradation. All four of these problems affect primarily the stability of the match, or authentic, distribution of template comparison scores rather than the non-match, or imposter, distribution of scores. (...) In this sense, these results confirm the security of iris biometrics in an identity verification scenario. We consider how these problems affect the usability and security of iris biometrics in large-scale applications, and suggest possible remedies. (shrink)

_"One of the most important political books of 2018."—Rod Dreher, ___American Conservative__ Of the three dominant ideologies of the twentieth century—fascism, communism, and liberalism—only the last remains. This has created a peculiar situation in which liberalism’s proponents tend to forget that it _is _an ideology and not the natural end-state of human political evolution. As Patrick Deneen argues in this provocative book, liberalism is built on a foundation of contradictions: it trumpets equal rights while fostering incomparable material inequality; its (...) legitimacy rests on consent, yet it discourages civic commitments in favor of privatism; and in its pursuit of individual autonomy, it has given rise to the most far-reaching, comprehensive state system in human history. Here, Deneen offers an astringent warning that the centripetal forces now at work on our political culture are not superficial flaws but inherent features of a system whose success is generating its own failure.

This book steers a middle course between two opposing conceptions that currently dominate the field of semantics, the logical and cognitive approaches. Patrick Duffley brings to light the inadequacies of both of these frameworks, arguing that linguistic semantics must be based on the linguistic sign itself and on the meaning that it conveys across the full range of its uses. The book offers 12 case studies that demonstrate the explanatory power of a sign-based semantics, dealing with topics such as (...) complementation with aspectual and causative verbs, control and raising, wh- words, full-verb inversion, and existential-there constructions. It calls for a radical revision of the semantics/pragmatics interface, proposing that the dividing line be drawn between content that is linguistically encoded and content that is not encoded but still communicated. While traditional linguistic analysis often places meaning at the level of the sentence or construction, this volume argues that meaning belongs at the lower level of linguistic items, where the linguistic sign is stored in a stable, permanent, and direct relation with its meaning outside of any particular context. Building linguistic analysis from the ground up in this way provides it with a more0solid foundation and increases its explanatory power. (shrink)

This essay addresses a stream of thought manifested in some forms of social justice activism – namely, that members of marginalized groups have privileged insight into the nature of social reality which others cannot understand, much less critique. This position, which I call “epistemic isolationism,” seems to rest on the claim that the knowledge that is embedded in lived experience is incommunicable. The essay proceeds in three parts: first, there is a brief overview of standpoint epistemology, including a recent version (...) which seems to support epistemic isolationism. Second, there is an explication of the concept of “lived experience” as developed by Wilhelm Dilthey. Third, there is an argument against the claim that lived experience is incommunicable, drawing from the work of Dilthey, Hans-Georg Gadamer, and Paul Ricoeur. The payoff of the argument is that sharing lived experience through expressions like literature and narrative inspires mutual recognition and respect which can, in turn, support a robust form of solidarity and serve as a foundation for more effective social justice advocacy.

This book examines the theory and practice of argument in primary, secondary and tertiary education. Several of its chapters offer theoretical discussion of the forms and functions of argument within social, philosophical, historical and rhetorical contexts.

Social entrepreneurship activity continues to surge tremendously in market and economic systems around the world. Yet, social entrepreneurship theory and understanding lag far behind its practice. For instance, the nature of the entrepreneurial discovery phenomenon, a critical area of inquiry in general entrepreneurship theory, receives no attention in the specific context of social entrepreneurship. To address the gap, we conceptualize social entrepreneurial discovery based on an extension of corporate social responsibility into social entrepreneurship contexts. We develop a model that emphasizes (...) mobilization and timing as underpinnings of social entrepreneurial discovery and offer distinct conceptual aspects and theoretic propositions instrumental to future social entrepreneurship research.

How are we to make sense of madness and psychosis? For most of us the words conjure up images from television and newspapers of seemingly random, meaningless violence. It is something to be feared, something to be left to the experts. But is madness best thought of as a medical condition? Psychiatrists and the drug industry maintain that psychoses are brain disorders amenable to treatment with drugs, but is this actually so? There is no convincing evidence that the brain is (...) disordered in psychosis, yet governments across the world are investing huge sums of money on mental health services that take for granted the idea that psychosis is an illness to be treated with medication. Although some people who use mental health services find medication helpful, many do not, and resist the idea that their experiences are symptoms of illnesses like schizophrenia. Consequently they are forced into having treatment against their wishes. So, how do we make sense of this situation? Postpsychiatry addresses these questions. It involves an attempt to rethink some of the fundamental assumptions of mental health work, showing how recent developments in philosophy and ethics can help us to clarify some of the dilemmas and conflicts around different understandings of madness. Throughout, the authors examine the conflicting ways in which politicians, academics, and mental health professionals appear to understand madness, and contrast this with voices and experiences that are usually excluded - those of the people who use mental health services. They then examine the power of psychiatry to shape how we understand ourselves and our emotions, before considering some of the basic limitations of psychiatry as science to make madness meaningful. In the final section of the book they draw on evidence from service users and survivors, the humanities and anthropology, to point out a new direction for mental health practice. This new direction emphasises the importance of cultural contexts in understanding madness, placing ethics before technology in responding to madness, and minimising 'therapeutic' coercion. (shrink)

Recent research into cultural transmission suggests that humans are disposed to learn, remember, and transmit certain types of information more easily than others, and that any information that is passed between people will be subjected to cognitive selective pressures that alter the content and structure so as to make it maximally transmittable. This paper presents a review of emerging research on content biases in cultural evolution with relevance to the transmission of popular narratives. This is illustrated with content analysis of (...) urban legends, which found that most exploited at least one known content bias, with emotional information and social information being the most frequent. We argue that the narratives do not succeed because of the transmission of adaptively relevant information but because of their exploitation of content biases in human cognition. (shrink)

This book offers a comprehensive overview of the arguments relating to the extent and manner to which social influences enable epistemic agents.

An e-mail discussion can be rendered into print in several ways. Rather than trying to imitate a genuine conversation, this is a personal essay containing comments and replies by the other contributors. Most of the substantial points made in the e-mail discussion are contained here, although not always in the order they happened.

As much a doubter as a believer, Emily Dickinson often expressed views about God in general—and God with respect to suffering in particular. In many of her poems, she contemplates the question posed by countless theologians and poets before her: how can one reconcile a benevolent deity with evil in the world? Examining Dickinson’s perspectives on the role played by a supposedly omnipotent and all-loving God in a world marked by violence and pain, Patrick Keane initially focuses on her (...) poem “Apparently with no surprise,” in which frost, a “blonde Assassin,” beheads a “happy Flower,” a spectacle presided over by “an Approving God.” This tiny lyric,Keane shows, epitomizes the poet’s embattled relationship with the deity of her Calvinist tradition. Although the problem of sufferingis usually couched in terms of natural disasters or human injustice, Dickinson found new ways of considering it. By choosing a flower as her innocent “victim,” she bypassed standard “answers” to the dilemma in order to focus on the problem in its purest symbolic form. Keane goes on toprovide close readings of many of Dickinson’s poems and letters engaging God, showing how she addressed the challenges posed—by her own experience and by an innate skepticism reinforced by a nascent Darwinism—to the argument from design and the concept of a benevolent deity. More than a dissection of a single poem, Keane’s book is a sweeping personal reflection on literature and religion, faith and skepticism, theology and science. He traces the evolving history of the Problem of Suffering from the Hebrew Scriptures, through the writings of Paul, Augustine, and Aquinas, to the most recent theological and philosophical studies of the problem. Keane is interested in _how_ readers today respond to Emily Dickinson’s often combative poems about God; at the same time, she is located as a poet whose creative life coincided with the momentous changes and challenges to religious faith associated with Darwin andNietzsche.Keane also considers Dickinson’s poems and letters in the context of the great Romantic tradition, as it runs fromMilton throughWordsworth, demonstrating how thework of these poets helps illuminate Dickinson’s poetry and thought. Because Dickinson the poet was also Emily the gardener, her love of flowers was an appropriate vehicle for her observations on mortality and her expressions of doubt. _Emily Dickinson’s Approving God _is a graceful study that reveals not only the audacity of Dickinson’s thought but also its relevance to modern readers. In light of ongoing confrontations between Darwinism and design, science and literal conceptions of a divine Creator, it is an equally provocative read for students of literature and students of life.

Although the second and third University Discourses in Newman’s Idea of a University are well known for according theology a place in a university education by showing the relationship of theology to the other sciences, this essay points out that Newman was also arguing against the “natural theology” of British thinkers like William Paley, Lord Brougham, Sir Robert Peel, and Bishop Edward Maltby, who maintained that the study of the natural sciences would necessarily lead to religion; Newman objected that this (...) kind of “natural theology” could easily lead to deism or pantheism.

THE emotive theory of ethics made its first brief and rather tentative appearance in The Meaning of Meaning by Ogden and Richards in 1922. It did not gain currency, however, nor receive anything like a complete formulation until it was adopted by Logical Positivism, and in particular by A J Ayer in Language, Truth and Logic. Ayer’s account was soon superseded by that of Charles L Stevenson, whose views were finally elaborated in Ethics and Language in 1942. This, the classic (...) statement of emotivism, is one of the great works of moral philosophy of this century, worthy to be ranked with the Principia Ethica of G E Moore. (shrink)

Locke famously claimed that morality was capable of demonstration. But he also refused to provide a system of demonstrative morality. This paper addresses the mismatch between Locke’s stated views and his actual philosophical practice. While Locke’s claims about demonstrative morality have received a lot of attention it is rare to see them discussed in the context of his general theory of demonstration and his specific discussions of particular demonstrations. This paper explores Locke’s general remarks about demonstration as well as his (...) claims about demonstration in natural philosophy, mathematics, and morality. Careful attention to these detailed discussions motivates a reevaluation of Locke’s views on demonstrative knowledge of morality. Specifically, while Locke did believe that some demonstrative moral knowledge might be in-principle available to us he also believed that facts about the difficulty of demonstration meant that this knowledge would in-practice be largely unattainable.
