Categorical loudness scaling (CLS) measures provide useful information about an individual’s loudness perception across the dynamic range of hearing. A probability model of CLS categories has previously been described as a multi-category psychometric function (MCPF). In the study, a representative “catalog” of potential listener MCPFs was used in conjunction with maximum-likelihood estimation to derive CLS functions for participants with normal hearing and with hearing loss. The approach of estimating MCPFs for each listener has the potential to improve the accuracy of (...) the CLS measurements, particularly when a relatively low number of data points are available. The present study extends the MCPF approach by using Bayesian inference to select stimulus parameters that are predicted to yield maximum expected information (MEI) during data collection. The accuracy and reliability of the MCPF-MEI approach were compared to the standardized CLS measurement procedure (ISO16832:2006). A non-adaptive, fixed-level, paradigm served as a “gold-standard” for this comparison. The test time required to obtain measurements in the standard procedure is a major barrier to its clinical uptake. Test time was reduced from approximately 15 minutes to approximately 3 minutes with the MEI-adaptive procedure. Results indicated that the test-retest reliability and accuracy of the MCPF-MEI adaptive procedures were similar to the standardized CLS procedure. Computer simulations suggest that the reliability and accuracy of the MEI procedure were limited by intrinsic uncertainty of the listeners represented in the MCPF catalog. In other words, the MCPF provided insufficient predictive power to significantly improve adaptive-tracking efficiency under practical conditions. Concurrent optimization of both the MCPF catalog and the MEI-adaptive procedure have the potential to produce better results. Regardless of the adaptive-tracking method used in the CLS procedure, the MCPF catalog remains clinically useful for enabling maximum-likelihood determination of loudness categories. (shrink)

Guided by neuroscience, animal behavior, evolution, philosophy, and psychology, Asma burrows deep into the human psyche to look right at the enigmatic but powerful engine that is our improvisational creativity—the source, he argues, of our remarkable imaginational capacity. How is it, he asks, that a story can evoke a whole world inside of us? How are we able to rehearse a skill, a speech, or even an entire scenario simply by thinking about it? How does creativity go beyond experience and (...) help us make something completely new? And how does our moral imagination help us sculpt a better society? As he shows, we live in a world that is only partly happening in reality. Huge swaths of our cognitive experiences are made up by “what-ifs,” “almosts,” and “maybes,” an imagined terrain that churns out one of the most overlooked but necessary resources for our flourishing: possibilities. Considering everything from how imagination works in our physical bodies to the ways we make images, from the mechanics of language and our ability to tell stories to the creative composition of self-consciousness, Asma expands our personal and day-to-day forms of imagination into a grand scale: as one of the decisive evolutionary forces that has guided human development from the Paleolithic era to today. The result is an inspiring look at the rich relationships among improvisation, imagination, and culture, and a privileged glimpse into the unique nature of our evolved minds. (shrink)

From the school yard to the workplace, there’s no charge more damning than “you’re being unfair!” Born out of democracy and raised in open markets, fairness has become our de facto modern creed. The very symbol of American ethics—Lady Justice—wears a blindfold as she weighs the law on her impartial scale. In our zealous pursuit of fairness, we have banished our urges to like one person more than another, one thing over another, hiding them away as dirty secrets of our (...) humanity. In Against Fairness, polymath philosopher Stephen T. Asma drags them triumphantly back into the light. Through playful, witty, but always serious arguments and examples, he vindicates our unspoken and undeniable instinct to favor, making the case that we would all be better off if we showed our unfair tendencies a little more kindness—indeed, if we favored favoritism. Conscious of the egalitarian feathers his argument is sure to ruffle, Asma makes his point by synthesizing a startling array of scientific findings, historical philosophies, cultural practices, analytic arguments, and a variety of personal and literary narratives to give a remarkably nuanced and thorough understanding of how fairness and favoritism fit within our moral architecture. Examining everything from the survival-enhancing biochemistry that makes our mothers love us to the motivating properties of our “affective community,” he not only shows how we favor but the reasons we should. Drawing on thinkers from Confucius to Tocqueville to Nietzsche, he reveals how we have confused fairness with more noble traits, like compassion and open-mindedness. He dismantles a number of seemingly egalitarian pursuits, from classwide Valentine’s Day cards to civil rights, to reveal the envy that lies at their hearts, going on to prove that we can still be kind to strangers, have no prejudice, and fight for equal opportunity at the same time we reserve the best of what we can offer for those dearest to us. Fed up with the blue-ribbons-for-all absurdity of "fairness" today, and wary of the psychological paralysis it creates, Asma resets our moral compass with favoritism as its lodestar, providing a strikingly new and remarkably positive way to think through all our actions, big and small.

Hailed as "a feast" (Washington Post) and "a modern-day bestiary" (The New Yorker), Stephen Asma's On Monsters is a wide-ranging cultural and conceptual history of monsters--how they have evolved over time, what functions they have served for us, and what shapes they are likely to take in the future. Beginning at the time of Alexander the Great, the monsters come fast and furious--Behemoth and Leviathan, Gog and Magog, Satan and his demons, Grendel and Frankenstein, circus freaks and headless children, (...) right up to the serial killers and terrorists of today and the post-human cyborgs of tomorrow. Monsters embody our deepest anxieties and vulnerabilities, Asma argues, but they also symbolize the mysterious and incoherent territory beyond the safe enclosures of rational thought. Exploring sources as diverse as philosophical treatises, scientific notebooks, and novels, Asma unravels traditional monster stories for the clues they offer about the inner logic of an era's fears and fascinations. In doing so, he illuminates the many ways monsters have become repositories for those human qualities that must be repudiated, externalized, and defeated. (shrink)

How we feel is as vital to our survival as how we think. This claim, based on the premise that emotions are largely adaptive, serves as the organizing theme of Why We Need Religion. This book is a novel pathway in a well-trodden field of religious studies and philosophy of religion. Stephen Asma argues that, like art, religion has direct access to our emotional lives in ways that science does not. Yes, science can give us emotional feelings of wonder (...) and the sublime--we can feel the sacred depths of nature--but there are many forms of human suffering and vulnerability that are beyond the reach of help from science. Different emotional stresses require different kinds of rescue. Unlike secular authors who praise religion's ethical and civilizing function, Asma argues that its core value lies in its emotionally therapeutic power. No theorist of religion has failed to notice the importance of emotions in spiritual and ritual life, but truly systematic research has only recently delivered concrete data on the neurology, psychology, and anthropology of the emotional systems. This very recent "affective turn" has begun to map out a powerful territory of embodied cognition. Why We Need Religion incorporates new data from these affective sciences into the philosophy of religion. It goes on to describe the way in which religion manages those systems--rage, play, lust, care, grief, and so on. Finally, it argues that religion is still the best cultural apparatus for doing this adaptive work. In short, the book is a Darwinian defense of religious emotions and the cultural systems that manage them. (shrink)

This article is a rebuttal to Robert G. Cavin and Carlos A. Colombetti’s article, “Assessing the Resurrection Hypothesis: Problems with Craig’s Inference to the Best Explanation,” which argues that the Standard Model of current particle physics entails that non-physical things (like a supernatural God or a supernaturally resurrected body) can have no causal contact with the physical universe. As such, they argue that William Lane Craig’s resurrection hypothesis is not only incompatible with the notion of Jesus physically appearing to the (...) disciples, but the resurrection hypothesis is significantly limited in both its explanatory scope and explanatory power. This article seeks to demonstrate why their use of the Standard Model does not logically entail a rejection of the physical resurrection of Jesus when considering the scope and limitations of science itself.

The concepts of form and function have traditionally been defined in terms of biology and then extended to other disciplines. Stephen T. Asma examines the various interpretations of form and function in science and philosophy, reflecting on the philosophical presuppositions underlying the work of Geoffroy, Cuvier, Darwin, and others. -/- In the continental tradition of Canguilhem and Foucault, Asma's treatment of the historical form/function dispute analyzes the complex interactions among ideologies, metaphysical commitments, and research programs. Following Form and Function (...) is a significant contribution to the history of science, history of philosophy, and disputes within contemporary biology. (shrink)

In this paper I shall discuss a certain theodicy, or line of argument in response to the problem of evil, viz, the so-called ‘free will defence’. What I propose to do is defend this theodicy against an objection that has been made to it in recent years.

Theists typically believe the following two propositions: God is omniscient, and Human beings are free. Are they consistent? In order to decide, we must first ask what they mean. Roughly, let us say that a being is omniscient if for any proposition he knows whether it is true or false. Since I have no wish to deny that there are true and false propositions about future states of affairs , omniscience includes foreknowledge, which we can say is knowledge of the (...) truth value of propositions about future states of affairs. For example, I believe the proposition ‘Davis will wear shoes tomorrow’ is true today, and if it is true today, i.e. if I will wear shoes tomorrow, an omniscient being knows today that it is true – and, if this being is eternally omniscient, he knew it millions of years ago.

Let me begin with a true story. Years ago, early in my career as a professor of philosophy, I had a fascinating series of conversations with a student whom I will call Peter. He was a bright and incisive senior, with a double major in philosophy and psychology. Raised in a religious family, the son of a Christian minister, he was himself unable to believe. His doubts were too strong. But the odd fact was that he genuinely wanted to believe. (...) His religious scepticism deeply troubled him; part of him envied the faith of his parents. How do you go about making yourself believe?, he asked me. How do you go about having the kinds of religious experiences that lead people to faith? These were long and intense conversations, and I was unable to move Peter away from his doubts. So far as I know he is still a sceptic. (shrink)

The natural history museum is a place where the line between "high" and "low" culture effectively vanishes--where our awe of nature, our taste for the bizarre, and our thirst for knowledge all blend happily together. But as Stephen Asma shows in Stuffed Animals and Pickled Heads, there is more going on in these great institutions than just smart fun. Asma takes us on a wide-ranging tour of natural history museums in New York and Chicago, London and Paris, interviewing curators, (...) scientists, and exhibit designers, and providing a wealth of fascinating observations. We learn how the first museums were little more than high-toned side shows, with such garish exhibits as the pickled head of Peter the Great's lover. In contrast, today's museums are hot-beds of serious science, funding major research in such fields as anthropology and archaeology. "Rich in detail, lucid explanation, telling anecdotes, and fascinating characters.... Asma has rendered a fascinating and credible account of how natural history museums are conceived and presented. It's the kind of book that will not only engage a wide and diverse readership, but it should, best of all, send them flocking to see how we look at nature and ourselves in those fabulous legacies of the curiosity cabinet."--The Boston Herald.

After a long hiatus, psychology and philosophy are returning to formal study of imagination. While excellent work is being done in the current environment, this article argues for a stronger thesis than usually adopted. Imagination is not just a peripheral feature of cognition or a domain for aesthetic research. It is instead the core operating system or cognitive capacity for humans and has epistemic and therapeutic functions that ground all our sense-making activities. A sketch of imagination as embodied cognition is (...) offered, followed by suggestions of how to organize imagination studies into a more rigorous science–humanities research area. (shrink)

Recently a new question has emerged in the philosophy of religion: not whether God exists, but whether God’s existence is or would be preferable. The existing literature on the subject is sparse. The present essay, in dialogue form, is an attempt to marshal and evaluate arguments on both sides.

Philosopher Davis argues that Christian belief in the resurrection is rational on historical, philosophical, and theological grounds. Each of the book's ten chapters takes up a different aspect of the Christian concept of bodily resurrection and subsequently deals with such matters as perservation of personal identity and soul-body dualism, issues in biblical scholarship, and the reliability of New Testament accounts.

Let’s call “Cartesian omnipotence” the view that an omnipotent being can bring about any state of affairs at all, even logically impossible ones. The present paper explores what can be said in support of CO. It turns out that several powerful and interesting arguments can be given in its defense, although in the end, along with the vast majority of philosophers of religion, I reject it.

Philosophers and scientists have historically conceptualized race according to two main metaphors; internal differentiation (theological, philosophical and genetic), and external differentiation (environmental). This paper examines these metaphors and theories in Descartes, Kant, Hegel, and also Darwin and the subsequent racial theories of recent history. The paper argues that the externalist metaphor has a more liberal and potentially egalitarian tradition.

Christian Philosophical Theology constitutes a Christian philosopher's look at various crucial topics in Christian theology, including belief in God, the nature of God, the Trinity, christology, the resurrection of Jesus, the general resurrection, redemption, and theological method.

While the work is written from a broadly Reformed Protestant perspective and the author does not avoid controversial topics, the aim is to present a (...) 'merely Christian' world view. That is, Stephen T. Davis attempts to write as much as possible from the perspective of the broad centre of Christian understanding. (shrink)

This article considers the concepts of revelation and inspiration. The two notions are distinct but closely connected in Christian theology; they come together preeminently in discussions of the Bible. The purpose of revelation is to bring it about that humans come into a personal relationship with God, one that involves freely chosen love as well as worship and obedience. Inspiration is that influence of the Holy Spirit on the writing of the Bible which ensures that the words of its various (...) texts are appropriate both for the role which they play in Scripture and for the overall salvific purpose of Scripture itself. In other words, working in conjunction with the human author, God ensures that the words written are revelatory and fit God's purposes. Because of inspiration, God speaks to us in the Bible. Scripture is not just a record of revelation; it in itself is revelatory. (shrink)

This work is an examination of the metaphysical presuppositions involved in the science of organic form. Taking the dichotomy of structuralism versus functionalism in nineteenth century biology as the central subject of my study, I explore a network of unquestioned premises and isolate areas where empirical research programs and underlying metaphysical commitments both inform and hinder each other. ;I begin with the Cuvier-Geoffroy debate of 1830--a debate that clearly articulates the tensions between structuralist and functionalist approaches to organic form. On (...) the side of functionalism, I am led to confront the rich concept of teleological causality. The concept of teleology, frequently taken to be semantically univocal, in fact unfolds into a cluster of related notions. I begin to demarcate significant differences between "intentional," "heuristic," "cosmic," and "organismic" teleology. On the side of structuralism, I set out to unearth the presuppositions of materialist versus idealist conceptions of structure--showing where naturalists have been both liberated and enslaved by their respective metaphysical commitments. With the basic divisions between structuralist and functionalist drawn, I set out to trace the dichotomy through the paradigm shift from fixism to transformism. ;In Darwin's system the structural/functional tensions become synthesized into complementary principles of causality. Here I explore the underlying presuppositional shifts which enabled Darwin to harmonize the previously intractable oppositions. These shifts include: rethinking teleology without "design," rethinking the archetype as real progenitor, and adopting a pluralistic perspective regarding causal mechanisms. ;The relative success of Darwin's appropriation of structuralism and functionalism leads to a discussion of the dichotomous character of the central subject itself. I argue that at the root of the dichotomous characterization of structure and function lies an impoverished understanding of teleology. I then offer "organicist" teleology as a powerful alternative to the French-Anglo tradition of "intentional" teleology. Presupposing the alternative teleology forms a challenge to the way in which French-Anglo naturalists have understood structural and functional relations. Together with Darwin's causal pluralism, a richer notion of teleology provides a different set of metaphysical assumptions and leads to an alternative model for empirical research programs. (shrink)

How do we prove the existence of God? This book tackles head-on this fundamental question. It examines a cross-section of theistic proofs, explaining in clear terms what they are and what they try to accomplish.

Asma, a professor of Buddhism at Columbia College in Chicago and the author of Stuffed Animals and Pickled Heads (2001), recounts his intense and revelatory Cambodian adventures while teaching at Phnom Penh's Buddhist Institute. In an electrifying and frank mix of hair-raising anecdotes and expert analysis, he explicates the vast difference between text-based Buddhist teachings and daily life in a poor and politically volatile Buddhist society. Amid tales of massage parlors, marijuana-spiced pizza, and bloodshed, he cogently explains how Theravada Buddhism, (...) the form practiced throughout Southeast Asia, differs from the Buddhism Westerners are familiar with, and how entwined it is with animistic beliefs. This fusion of Buddhist rationalism with superstition is but one of many juxtapositions Asma relishes as he assesses the terrible scars left by the Khmer Rouge and the profound self-possession of the people he meets. His striking insights into Cambodian reality lead to a bracing critique of American pop culture and the manipulative tactics of Cambodia-based fundamentalist Protestant missionaries--and an incisive argument for learning about and respecting religions other than one's own.

Traditionally, Darwin has been grouped with the functionalists because natural selection (an adaptational mechanism) plays the prominent role in shaping organic form. In this paper, I sketch the dichotomy of functionalism versus structuralism and then argue that Darwin cannot be characterized adequately with this dichotomy. I argue that Darwin can incorporate both causal stories because he makes two important modifications to the traditional metaphysical presuppositions. I then offer some brief reflections on the import of Darwin's causal pluralism for the Philosophy (...) of Science. (shrink)

The ability to evaluate scientific claims made in various media sources is a critical component of scientific literacy. This study compares how a group of 12th grade students and a group of specialists, including scientists and policy analysts with expertise in global warming, evaluated an editorial about global warming published by an oil company on the World Wide Web. Participants were asked to read the editorial and were asked a set of interview questions about it. Examples from the specialists’ interviews (...) indicate the kinds of responses that are possible with in-depth scientific knowledge. In comparison, although some examples from the students’interviews illustrate competent performance for a nonexpert, other student responses illustrate possible pitfalls. The approach of the present study affords a constructive route for formulating goals for scientific literacy. The approach permits identifying examples of students evaluating scientific claims in more or less competent ways—claims that are in the context of an important socioscientific issue and an actual media source.

The use of automobiles is a major cause of worldwide environmental disruption, including global warming. Policies designed to curb the environmental impact of automobiles present tradeoffs that high school graduates should be prepared to evaluate. This article compares how a group of high school students and a group of specialists with expertise in transportation issues, climate change, or both evaluated two policies designed to ameliorate the impact of automobiles. The policies were a $1 per gallon gasoline tax and a “feebate” (...) policy, which creates additional fees on the purchase of fuel-inefficient automobiles but offers rebates on the purchase of fuel-efficient vehicles. One goal of the study was to identify knowledge and beliefs that students bring to the task as well as to identify misconceptions they may have. Another goal was to identify knowledge used by the specialists that may be accessible or useful to high school students. (shrink)

The present essay is a response to Keith Ward’s recent book, Christ and the Cosmos. While deeply appreciative of this fine book, I raise two criticisms of it: Ward’s claim that we can know nothing of the divine essence has disturbing implications, the main one of which is that there may be large disjunctions between what God has revealed to us about the divine nature and the divine nature in itself. Ward’s criticisms of the social theory of the Trinity are (...) not compelling and indeed edge his own view close to modalism. (shrink)
