In the last decade, reading research has seen a paradigmatic shift. A new wave of computational models of orthographic processing that offer various forms of noisy position or context-sensitive coding have revolutionized the field of visual word recognition. The influx of such models stems mainly from consistent findings, coming mostly from European languages, regarding an apparent insensitivity of skilled readers to letter order. Underlying the current revolution is the theoretical assumption that the insensitivity of readers to letter order reflects the (...) special way in which the human brain encodes the position of letters in printed words. The present article discusses the theoretical shortcomings and misconceptions of this approach to visual word recognition. A systematic review of data obtained from a variety of languages demonstrates that letter-order insensitivity is neither a general property of the cognitive system nor a property of the brain in encoding letters. Rather, it is a variant and idiosyncratic characteristic of some languages, mostly European, reflecting a strategy of optimizing encoding resources, given the specific structure of words. Since the main goal of reading research is to develop theories that describe the fundamental and invariant phenomena of reading across orthographies, an alternative approach to model visual word recognition is offered. The dimensions of a possible universal model of reading, which outlines the common cognitive operations involved in orthographic processing in all writing systems, are discussed. (shrink)

Face perception is a highly conserved process that directs our attention from infancy and is supported by specialized neural circuitry. Oxytocin can increase accuracy and detection of emotional faces, but these effects are mediated by valence, individual differences, and context. We investigated the temporal dynamics of oxytocin’s influence on the neural substrates of face perception using event related potentials (ERP). In a double blind, placebo controlled within-subject design, 21 healthy male adults inhaled oxytocin or placebo and underwent ERP imaging during (...) two face processing tasks. Experiment 1 investigated effects of oxytocin on neural correlates of fearful versus neutral facial expressions, and Experiment 2 manipulated point-of-gaze to neutral faces. In Experiment 1, we found that oxytocin reduced N170 latency to fearful faces. In Experiment 2, N170 latency was decreased when participant gaze was directed to the eyes of neutral faces; however, there were no oxytocin-associated effects in response to different facial features. Findings suggest oxytocin modulates early stages of social perception for socially complex information such as emotional faces relative to neutral. These results are consistent with models suggesting oxytocin impacts the salience of socially informative cues during processing, which leads to downstream effects in behavior. Future work should examine how oxytocin affects neural processes underlying basic components of social behavior (such as, face perception) while varying emotional expression of stimuli or comparing different characteristics of participants (e.g., gender, personality traits).

Do our lives have meaning? Should we create more people? Is death bad? Should we commit suicide? Would it be better to be immortal? Should we be optimistic or pessimistic? Since Life, Death, and Meaning: Key Philosophical Readings on the Big Questions first appeared, David Benatar's distinctive anthology designed to introduce students to the key existential questions of philosophy has won a devoted following among users in a variety of upper-level and even introductory courses.

The book's key questions concern whether we have a right to believe whatever we choose and whether we have significant control over our beliefs. After exploring four case studies in which the question of a right to believe arises and querying what epistemic obligations are, we consider how epistemic obligations might be grounded, whether in prudence, morality, or human virtues. Some argue that epistemic excellence is less concerned with our obligations to believe the truth and avoid falsehood than with seeing (...) that the beliefs we hold are justified. We argue that our epistemic responsibility is best fulfilled somewhere in between the strict objectivist and strict subjectivist views. We proceed to defend the thesis that we have not only indirect but direct control over our beliefs. We then examine the nature of belief, contending for belief as both disposition and an action. In the final chapter we discuss the relation between epistemic obligations and moral accountability. (shrink)

To understand what a fallacy is one needs to understand what a bad argument is and what it is for an argument to appear good. I will argue that from an intuitive standpoint a good argument should be understood in roughly the way Richard Feldman has proposed, that is, as an argument that gives people reason to believe its conclusion. However, I will also argue that an externalist condition that requires that the premises really do support the conclusion must (...) be added to the internalist account which only requires that a person be justified in believing the premises support the conclusion.

It is generally considered the case that an authorial preface is an author’s opportunity to give the reader a hand in interpreting the work he or she is about to read. It is strange then that the Preface to Wittgenstein’s Tractatus (1922) has often been overlooked. Max Black’s (1964) influential A Companion toWittgenstein’sTractatus, for example, passes over the Preface in silence. And even in the latest published edition of the so-called Prototractatus (1996), the Preface is the only part that appears (...) in hand-written facsimile but is not reproduced in typescript form. Perhaps an argument for not so-reproducing the Preface of the Pro- totractatus in typescript is also an argument for the importance of the Preface: not one letter of this early hand-written text of the Preface is different from the final published edition (I will return to this later). Only of late has the Preface to the Tractatus been seen as having any kind of focal importance.This recent interest in the Preface has largely been spawned by Cora Diamond’s and James Conant’s “New” view of Wittgenstein. This New view (designated as such subsequent to the publication in 2000 of the volume entitled The New Wittgenstein) uses the Preface as a central interpretive tool that, according to this view, shows that the Tractatus takes “a strong anti-metaphysical stand” which is “most explicit in Wittgenstein’s statements in the book’s Preface and concluding remarks.1”The third and fourth paragraphs of the Preface are seen as especially revealing of Wittgenstein’s anti-metaphysical purpose.

My overall aim here is to intersect two issues central to Max Velmans' wide-ranging paper. The first concerns one of the most vexing problems in consciousness research — how best to approach the terms 'mental' and 'physical'. The second looks at the phenomenology of volition, and the degree to which information presumably necessary for making voluntary conscious decisions is, or is not, present in consciousness. Velmans offers three general reasons to motivate his position: the physical world is 'causally closed' to (...) the influence of consciousness; consciousness does not contain the information necessary for making volitional decisions; conscious feelings of volition occur before the acts they supposedly cause. It seems to me that none of this holds up well under scrutiny. I will concentrate on the first two reasons, since I think they involve more basic and widespread aspects of consciousness research.

A new theory of how the brain constructs emotions that could revolutionize psychology, health care, law enforcement, and our understanding of the human mind Emotions feel automatic, like uncontrollable reactions to things we think and experience. Scientists have long supported this assumption by claiming that emotions are hardwired in the body or the brain. Today, however, the science of emotion is in the midst of a revolution on par with the discovery of relativity in physics and natural selection in biology--and (...) this paradigm shift has far-reaching implications for us all. Leading the charge is psychologist and neuroscientist Lisa Feldman Barrett, whose theory of emotion is driving a deeper understanding of the mind and brain, and shedding new light on what it means to be human. Her research overturns the widely held belief that emotions are housed in different parts of the brain and are universally expressed and recognized. Instead, she has shown that emotion is constructed in the moment, by core systems that interact across the whole brain, aided by a lifetime of learning. This new theory means that you play a much greater role in your emotional life than you ever thought. Its repercussions are already shaking the foundations not only of psychology but also of medicine, the legal system, child-rearing, meditation, and even airport security. Why do emotions feel automatic? Does rational thought really control emotion? How does emotion affect disease? How can you make your children more emotionally intelligent? How Emotions Are Made answers these questions and many more, revealing the latest research and intriguing practical applications of the new science of emotion, mind, and brain. (shrink)

Evidence and theory ranging from traditional philosophy to contemporary cognitive research support the hypothesis that consciousness has a two-part structure: a focused region of articulated experience surrounded by a field of relatively unarticulated, vague experience.William James developed an especially useful phenomenological analysis of this "fringe" of consciousness, but its relation to, and potential value for, the study of cognition has not been explored. I propose strengthening James′ work on the fringe with a functional analysis: fringe experiences work to radically condense (...) context information in consciousness; are vague because a more explicit representation of context information would overwhelm consciousness′ limited articulation capacity; help mediate retrieval functions in consciousness; and contain a subset of monitoring and control experiences that cannot be elaborated in focal attention and are "ineffable." In general, the phenomenology of the fringe is a consequence of its cognitive functions, constrained by consciousness′ limited articulation capacity. Crucial to monitoring and control is the feeling of "rightness." Rightness functions as a summary index of cognitive integration, representing, in the fringe, the degree of positive fit between a given conscious content and its parallel, unconsciously encoded context. Rightness appears analogous to the connectionist metric of global network integration, known variously as goodness-of-fit, harmony, or minimum energy. (shrink)

Non-sensory experiences represent almost all context information in consciousness. They condition most aspects of conscious cognition including voluntary retrieval, perception, monitoring, problem solving, emotion, evaluation, meaning recognition. Many peculiar aspects of non-sensory qualia (e.g., they resist being 'grasped' by an act of attention) are explained as adaptations shaped by the cognitive functions they serve. The most important nonsensory experience is coherence or "rightness." Rightness represents degrees of context fit among contents in consciousness, and between conscious and non-conscious processes. Rightness (not (...) familiarity) is the feeling-of-knowing in implicit cognition. The experience of rightness suggests that neural mechanisms "compute" signals indicating the global dynamics of network integration. (shrink)

Philosophy long sought to set knowledge on a firm foundation, through derivation of indubitable truths by infallible rules. For want of such truths and rules, the enterprise foundered. Nevertheless, foundationalism's heirs continue their forbears' quest, seeking security against epistemic misfortune, while their detractors typically espouse unbridled coherentism or facile relativism. Maintaining that neither stance is tenable, Catherine Elgin devises a via media between the absolute and the arbitrary, reconceiving the nature, goals, and methods of epistemology. In Considered Judgment, she argues (...) for a reconception that takes reflective equilibrium as the standard of rational acceptability. A system of thought is in reflective equilibrium when its components are reasonable in light of one another, and the account they comprise is reasonable in light of our antecedent convictions about the subject it concerns.Many epistemologists now concede that certainty is a chimerical goal. But they continue to accept the traditional conception of epistemology's problematic. Elgin suggests that in abandoning the quest for certainty we gain opportunities for a broader epistemological purview--one that comprehends the arts and does justice to the sciences. She contends that metaphor, fiction, emotion, and exemplification often advance understanding in science as well as in art. The range of epistemology is broader and more variegated than is usually recognized. Tenable systems of thought are neither absolute nor arbitrary. Although they afford no guarantees, they are good in the way of belief. (shrink)

The current paper synthesizes theory and data from the field of life history (LH) evolution to advance a new developmental theory of variation in human LH strategies. The theory posits that clusters of correlated LH traits (e.g., timing of puberty, age at sexual debut and first birth, parental investment strategies) lie on a slow-to-fast continuum; that harshness (externally caused levels of morbidity-mortality) and unpredictability (spatial-temporal variation in harshness) are the most fundamental environmental influences on the evolution and development of LH (...) strategies; and that these influences depend on population densities and related levels of intraspecific competition and resource scarcity, on age schedules of mortality, on the sensitivity of morbidity-mortality to the organism’s resource-allocation decisions, and on the extent to which environmental fluctuations affect individuals versus populations over short versus long timescales. These interrelated factors operate at evolutionary and developmental levels and should be distinguished because they exert distinctive effects on LH traits and are hierarchically operative in terms of primacy of influence. Although converging lines of evidence support core assumptions of the theory, many questions remain unanswered. This review demonstrates the value of applying a multilevel evolutionary-developmental approach to the analysis of a central feature of human phenotypic variation: LH strategy. (shrink)

This paper reports an analysis of the content of the codes of ethics of 15 professional business organizations in the United States, representing the broad range of disciplines found in business. The analysis was conducted to identify common ethical issues faced by business professionals. It was also structured to highlight ethical issues that are either unique to or of particular importance for business professionals. No attempt is made to make value judgments about either the codes of ethics studied or of (...) their content. General ethical values identified include honesty and integrity, general legal compliance, discreditable or harmful acts, and obligations related to social values. More business-specific issues include confidentiality, responsibilities to employers/clients, obligations to the profession, independence and objectivity, and business-specific legal and technical compliance issues.

Of all the problems facing science none are more challenging yet fascinating than those posed by consciousness. In The Science of Consciousness leading researchers examine how consciousness is being investigated in the key areas of cognitive psychology, neuropsychology and clinical psychology. Within cognitive psychology, special focus is given to the function of consciousness, and to the relation of conscious processing to nonconscious processing in perception, learning, memory and information dissemination. Neuropsychology includes examination of the neural conditions for consciousness and the (...) effects of brain damage. Finally, mind/body interactions in clinical and experimental settings are considered, including the somatic effects of imagery, biofeedback and placebo effects. Every chapter is written by an expert in the field. They each provide a clear overview of existing research along with an exciting new synthesis of consciousness studies. The The Science of Consciousness will be invaluable for students, researchers and clinicians interested in the developments and directions of this rapidly growing field. (shrink)

A great deal of interest in codes of ethics exists in both the business community and the academic community. Within the academic community, this interest has given rise to a number of studies of codes of ethics. Many of these studies have focused on the content of various codes.One important way the study of codes of ethics can be advanced is by applying formal tools of analysis to codes of ethics. An understanding of important dimensions that may differ across codes (...) of ethics, a common terminology to describe these dimensions, and a means to measure these dimensions will facilitate applying such tools. They will also facilitate discussion, enable comparisons, and advance our understanding of codes of ethics. The present paper describes a classification scheme to use in studying codes of ethics. This scheme uses six important dimensions to distinguish among codes of ethics: length, focus, level of detail, shape, thematic content, and tone. The paper also introduces metrics that can be used to measure the dimensions. (shrink)

James Sterba has constructed a powerful argument for there being a conflict between the presence of evil in the world and the existence of God. I contend that Sterba’s argument depends on a crucial assumption, namely, that God has an obligation to act according to the principle of meticulous providence. I suggest that two of his analogies confirm his dependence on this requirement. Of course, his argument does not rest on either of these analogies, but they are illustrative of the (...) role that meticulous providence plays in his argument. I then investigate the ethical principles Sterba invokes in his use of meticulous providence and suggest that not only do we often not predicate goodness of human persons based on these principles of obligation, but that these principles are much too stringent to function to determine moral obligations and moral goodness. From there, I contend that to think that God has a similar obligation regarding meticulous providence in order to be good encounters several serious problems, especially with respect to the soul-building Sterba wants to preserve. I conclude by considering Sterba’s reply in terms of a limited application of meticulous providence. (shrink)

“Clinical ethics consultants” have been practicing in the United States for about 50 years. Most of the earliest consultants—the “pioneers”—were “outsiders” when they first appeared at patients' bedsides and in the clinic. However, if they were outsiders initially, they acclimated to the clinical setting and became “insiders” very quickly. Moreover, there was some tension between traditional academics and those doing applied ethics about whether there was sufficient “critical distance” for appropriate reflection about the complex medical ethics dilemmas of the day (...) if one were involved in the decision making. Again, the pioneers deflected concerns by identifying and instituting safeguards to assure professional objectivity in clinical ethics consultation services. One might suggest that in moving inside and establishing normative practices, the pioneer clinical ethics consultants anticipated adoption of their routines and professionalization of the field.

Current debate on business ethics in Australia continues apace as the excesses of the 1980s are exposed. Codes of Ethics have been a high profile instrument in the American business scene. A survey of Australia''s largest business corporations reveals a different situation. Codes are not as commonly used, tend to refer to legal requirements and do not have as high a profile within the corporation. Given the changing legal framework in Australia a greater role for Codes of Ethics may emerge.

This collection of essays focuses on sacrifice in the context of Jewish and Christian scripture and is inspired by the thought and writings of Rene Girard. The contributors engage in a dialogue with Girard in their search for answers to key questions about the relation between religion and violence. The book is divided into two parts. The first opens with a conversation in which Rene Girard and Sandor Goodhart explore the relation between imitation and violence throughout human history, especially in (...) religious culture. It is followed by essays on the subject of sacrifice contributed by some of the most distinguished scholars in the field, including Bruce Chilton, Robert Daly, Louis Feldman, Michael Fishbane, Erich Gruen, and Alan Segal. The second part contains essays on specific scriptural texts. The authors explore new ways of applying Girardian analysis to episodes of sacrifice and scapegoating, demonstrating that fertile ground remains to further our understanding of violence in the Hebrew and Christian scriptures. "In increasing numbers, scholars are turning to the mimetic theory espoused by Rene Girard in their research for answers to key questions about religion and violence. For the first time, the editors of this volume place in conversation with each other scholars who, from the perspective of Christian and Jewish traditions and scholarship, engage from the perspective of mimetic theory the sacrificial and antisacrificial features of ancient Judaism and early Christianity and explore their subsequent trajectories." --_Martha Reineke, University of Northern Iowa _.

I argue that results from foraging theory give us good reason to think some evolutionary phenomena are indeterministic and hence that evolutionary theory must be probabilistic. Foraging theory implies that random search is sometimes selectively advantageous, and experimental work suggests that it is employed by a variety of organisms. There are reasons to think such search will sometimes be genuinely indeterministic. If it is, then individual reproductive success will also be indeterministic, and so too will frequency change in populations of (...) organisms employing such search. (shrink)

This highly original history of ideas considers the impact of Hegel on French philosophy from the 1920s to the present. As Baugh's lucid narrative makes clear, Hegel's influence on French philosophy has been profound, and can be traced through all the major intellectual movements and thinkers in France throughout the 20th Century from Jean Wahl, Sartre, and Bataille to Foucault, Deleuze, and Derrida. Baugh focuses on Hegel's idea of the "unhappy consciousness," and provides a bold new account of Hegel's early (...) reception in French intellectual history. (shrink)

Rightness, not familiarity, is the feeling of knowing. Rightness and familiarity are distinct at both the functional and phenomenological levels of analysis. In problem solving, for example, an unfamiliar solution can still feel right. Rightness is the fringe experience permeating all cases of felt meaning in consciousness, and can occur even when the retrieval of specific content is for whatever reason blocked (e.g., in a tip of the tongue experience). For the most extensive published treatment of rightness and fringe experience, (...) see Mangan (2003): "The conscious 'fringe': Bringing William James up to date" in Essential Sources in the Scientific Study of Consciousness, MIT press.

Newton certainly regarded his second law of motion in the Principia as a fundamental axiom of mechanics. Yet the works that came after the Principia, the major treatises on the foundations of mechanics in the eighteenth century—by Varignon, Hermann, Euler, Maclaurin, d’Alembert, Euler (again), Lagrange, and Laplace—do not record, cite, discuss, or even mention the Principia’s statement of the second law. Nevertheless, the present study shows that all of these scientists do in fact assume the principle that the Principia’s second (...) law asserts as a fundamental axiom in their mechanics. (For what that second law asserts, we rely on Newton’s own testimony.) Some, like Varignon and Hermann, assume the axiom implicitly, apparently unaware that any assumption is being made, while others, like Maclaurin and Euler, assume the axiom explicitly, apparently unaware that the assertion assumed is the second law as Newton himself understood it. But in every case these scientists employ the principle asserted by the Principia’s second law fundamentally, unaware that they should be citing Neutonus, Prin., Phil. Nat. Math., Lex II. (shrink)

The alleged conflict between religion and science most pointedly focuses on what it is to be human. Western philosophical thought regarding this has progressed through three broad stages: mind/body dualism, Neo-Darwinism, and most recently strong artificial intelligence (AI). I trace these views with respect to their relation to Christian views of humans, suggesting that while the first two might be compatible with Christian thought, strong AI presents serious challenges to a Christian understanding of personhood, including our freedom to choose, moral (...) choice itself, self-consciousness, and the relevance of God to our beginning, being, and ending.

The first proposition of the Principia records two fundamental properties of an orbital motion: the Fixed Plane Property (that the orbit lies in a fixed plane) and the Area Property (that the radius sweeps out equal areas in equal times). Taking at the start the traditional view, that by an orbital motion Newton means a centripetal motion – this is a motion ``continually deflected from the tangent toward a fixed center'' – we describe two serious flaws in the Principia's argument (...) for Proposition 1, an argument based on a polygonal impulse approximation. First, the persuasiveness of the argument depends crucially on the validity of the Impulse Assumption: that every centripetal motion can be represented as a limit of polygonal impulse motions. Yet Newton tacitly takes the Impulse Assumption for granted. The resulting gap in the argument for Proposition 1 is serious, for only a nontrivial analysis, involving the careful estimation of accumulating local errors, verifies the Impulse Assumption. Second, Newton's polygonal approximation scheme has an inherent and ultimately fatal disability: it does not establish nor can it be adapted to establish the Fixed Plane Property. Taking then a different view of what Newton means by an orbital motion – namely that an orbital motion is by definition a limit of polygonal impulse motions – we show in this case that polygonal approximation can be used to establish both the fixed plane and area properties without too much trouble, but that Newton's own argument still has flaws. Moreover, a crucial question, haunted by error accumulation and planarity problems, now arises: How plentiful are these differently defined orbital motions? Returning to the traditional view, that Newton's orbital motions are by definition centripetal motions, we go on to give three proofs of the Area Property which Newton ``could have given'' – two using polygonal approximation and a third using curvature – as well as a proof of the Fixed Plane Property which he ``almost could have given.''.

Standard models of statistical explanation face two intractable difficulties. In his 1984 Salmon argues that because statistical explanations are essentially probabilistic we can make sense of statistical explanation only by rejecting the intuition that scientific explanations are contrastive. Further, frequently the point of a statistical explanation is to identify the etiology of its explanandum, but on standard models probabilistic explanations often fail to do so. This paper offers an alternative conception of statistical explanations on which explanations of the frequency of (...) a property consist in the derivation of that frequency from a statistical specification of the mechanism by which instances of the relevant property are produced. Such explanations are contrastive precisely because they identify the determinate causal etiologies of their explananda. (shrink)

Restorative Free Will examines free will as an adaptive capacity that evolved in humans and many other species, and restores free will to species excluded by claims of human uniqueness. Restorative Free Will recognizes the basic biological value of both libertarian and compatibilist elements of free will, and explains how these traditionally opposed accounts of free will capture an essential element of foraging animals' free will.

Launched in 1982, the so-calledBerliner Wissenschaftsladen e. V.(WILAB) belonged to the scattered West-German ventures in “counter-science”. This article situates the origins of the “Laden” (~ workshop)—an “alternative” spin-off of sorts, spawned from the Technical University of Berlin—in the context of contemporary advances in regional science policy. In this connection, the ailing, de-industrializing “island city” arguably even played a certain pioneering role: elements of its multipronged “innovation offensive”, which peaked in the early-to-mid 1980s, were visible beyond city limits, including the trade (...) showBIG TECHand, notably, theBerlin Center for Innovation and New Enterprises(BIG), the FRG’s first start-up “incubator”, which opened in 1983.In other words, politically-minded scientists in tendency now had to deal with conditions that were less and less conducive to dreams of a “socially engaged” and “non-alienated” (counter-)science. Indeed, while hardly opposed to the new gospel of innovation, it’s not surprising that ventures such as WILAB, committed as they were to the production of “socially useful” science, found themselves increasingly marginalized. It’s as such a marginal venture, my argument goes, that WILAB’s prima facie hopeless attempt to initiate a different, more “humane” information technology sheds an instructive light on the emergence of “entrepreneurial” science in the FRG during the 1970s and 1980s.
