Recent investigations and theorising about category-specific deficits have begun to focus upon patients with progressive brain disease such as semantic dementia and Alzheimer's disease. In this commentary we briefly review what insights have been gained from studying patients of this type. We concentrate on four specific issues: the sensory/functional distinction, correlation between features, neuroanatomical considerations, and confounding factors.

The extended Church-Turing thesis posits that any computable function can be calculated efficiently by a probabilistic Turing machine. If this thesis held true, the global effort to build quantum computers might ultimately be unnecessary. The thesis would however be strongly contradicted by a physical device that efficiently performs a task believed to be intractable for classical computers. BosonSampling - the sampling from a distribution of n photons undergoing some linear-optical process - is a recently developed, and experimentally accessible example of (...) such a task [1].

Ralph Cudworth’s goal in his manuscript writings on freewill is to argue that our actions are in our own power in a robust sense that entails the ability to do otherwise. Cudworth’s unorthodox views about the nature of desire threaten to undermine this project, however. Cudworth maintains that only desire is able to distinguish good and evil and, consequently, that desire alone motivates our actions. Therefore, since Cudworth holds that desire itself is not in our own power, he appears (...) committed to the conclusion that our actions are not in our own power either. Cudworth’s solution, I argue, is to emphasize our inward responses to desire, which Cudworth does take to be in our own power. I focus in particular on attention: by directing attention differently in response to desire, Cudworth holds that we are able actively to influence the way in which desire motivates our actions. Our actions are in our own power, therefore, only because such inward responses to desire are in our own power. (shrink)

In his unpublished freewill manuscripts, Ralph Cudworth seeks to complete the project that he begins in The True Intellectual System of the Universe (1678) by arguing for an account of human liberty that avoids the opposing poles of necessitarianism and indifferency. I argue that Cudworth’s account rests upon a crucial distinction between the will and the power of freewill. Whereas we necessarily will the greater apparent good, freewill is a more fundamental power by which we endeavour to discern the (...) greater good before willing to pursue it. Cudworth thus opposes necessitarianism by arguing for a libertarian account of freewill while nonetheless rejecting the indifferentist claim that we can will contrary to the greater apparent good.

Henry More famously argues that all substances are extended, body and spirit alike. In The True Intellectual System of the Universe, More’s friend and fellow Cambridge Platonist Ralph Cudworth notes More’s position but refrains from criticizing it. By contrast, in a passage from one of Cudworth’s unpublished manuscripts that has escaped scholarly attention and that is included here as an appendix, Cudworth addresses More directly, raising objections against More’s view and responding to two of More’s arguments. My aim in (...) this paper is to provide a detailed analysis of Cudworth’s response to More in this passage. (shrink)

Ralph Cudworth’s The True Intellectual System of the Universe (1678) is credited with the first instance of the English word “consciousness” used in a distinctively philosophical sense. While Cudworth says little in the System about the nature of consciousness, he has more to say in his (largely unpublished) freewill manuscripts. I argue that, in these manuscripts, Cudworth distinguishes two kinds of consciousness, which I call “bare consciousness” and “reflective consciousness”. What both have in common is that each is a (...) kind of reflection or reflexive perception that therefore involves a “duplication” of the soul as both subject and object. While it is less clear how Cudworth takes these two kinds of consciousness to differ, I argue that the central difference for Cudworth is that, whereas bare consciousness is always directed towards individual cogitations, reflective consciousness is the kind of consciousness that the soul achieves through reflection upon itself as a whole. As a result, reflective consciousness introduces a unity into our experience that is not present at the level of bare consciousness. (shrink)

We determine precisely those locally finite varieties of unary algebras of finite type which, when augmented by a ternary discriminator, generate a variety with a decidable theory.

This book is a collection of secondary essays on America's most important philosophic thinkers—statesmen, judges, writers, educators, and activists—from the colonial period to the present. Each essay is a comprehensive introduction to the thought of a noted American on the fundamental meaning of the American regime.

To study how religiosity affects family business goals, we merge literatures on goal setting, temporal orientation, and family business to argue that family business goals can be distinguished into short-term and long-term orientations and propose that religiosity affects both orientations, but to varying degrees. Drawing on a sample of private U.S. family businesses and applying partial least squares structural equations modeling, we find tentative support that religiosity has a stronger positive effect on long-term goal orientation than on short-term goal orientation. (...) We discuss implications for theory development and future research involving religiosity and family business goals. (shrink)

Metamorphoses of the Zoo marshals a unique compendium of critical interventions that envision novel modes of authentic encounter that cultivate humanity's biophilic tendencies without abusing or degrading other animals. These take the form of radical restructurings of what were formerly zoos or map out entirely new, post-zoo sites or experiences. The result is a volume that contributes to moral progress on the inter-species front and eco-psychological health for a humankind whose habitats are now mostly citified or urbanizing.

Matthew H. Bowker offers a novel analysis of "experience": the vast and influential concept that has shaped Western social theory and political practice for the past half-millennium. While it is difficult to find a branch of modern thought, science, industry, or art that has not relied in some way on the notion of "experience" in defining its assumptions or aims, no study has yet applied a politically-conscious and psychologically-sensitive critique to the construct of experience. Doing so reveals that most (...) of the qualities that have been attributed to experience over the centuries — particularly its unthinkability, its correspondence with suffering, and its occlusion of the self — are part of unlikely fantasies or ideologies. By analyzing a series of related cases, including the experiential education movement, the ascendency of trauma theory, the philosophy of the social contract, and the psychological study of social isolation, the book builds a convincing case that ideologies of experience are invoked not to keep us close to lived realities and ‘things-in-themselves,’ but, rather, to distort and destroy true knowledge of ourselves and others. In spite of enduring admiration for those who may be called champions of experience, such as Michel de Montaigne, Ralph Waldo Emerson, and others treated throughout the work, the ideologies of experience ultimately discourage individuals and groups from creating, resisting, and changing our experience, urging us instead to embrace trauma, failure, deprivation, and self-abandonment.

Reading Certainty offers incisive historical analysis of the foundational questions of the Christian tradition: how are we to read scripture, and how can we know we are saved? This collection of essays honors the work and thought Susan E. Schreiner by exploring the import of these questions across a wide range of time periods. With contributions from renowned scholars and from Schreiner's students from her more than three decades of teaching, each of the contributions highlights the nexus of certainty, perception, (...) authority, and exegesis that has defined her scholarly work. Intellectual historians, early modernists, and scholars of Christianity will all appreciate this testament to Schreiner's influence. Contributors include: Vincent Evener, Bruce Gordon, Ralph Keen, Mark Lambert, Kevin J. Madigan, Richard A. Muller, Willemien Otten, Daniel Owings, Elizabeth Palmer, Karen Park, Barbara Pitkin, Ronald K. Rittgers, William Schweiker, Jonathan Strom, and Matthew Vanderpoel. (shrink)

Like philosophy itself, Dune explores everything from politics to art to life to reality, but above all, the novels ponder the mysteries of mind. Voyaging through psychic expanses, Frank Herbert hits upon some of the same insights discovered by indigenous people from the Americas. Many of these ideas are repeated in mainstream American and European philosophical traditions like pragmatism and existential phenomenology. These outlooks share a regard for mind as ecological, which is more or less to say that minds extend (...) beyond the brain into the rest of the body and the surrounding environment. -/- The cross-cultural strands in Dune tie closely to Herbert’s life and interests. An outdoorsman born in the Pacific West, he had an abiding bond with a friend from the Quileute tribe, Howie Hansen. Herbert advocated for aboriginal rights and crafted well-intentioned if slightly stereotypical tales about indigenous characters, partly based on his visits with Northwest tribes. Carl Jung (1875-1961), whose idea of collective consciousness echoes aboriginal views, was among Herbert’s European influences. So was existential phenomenology, especially as developed by Martin Heidegger (1889-1976). The names of characters in one of Herbert’s novels—The Santaroga Barrier—in fact coincide with terms that Heidegger used to articulate how emotionally colored coping with our environment defines our existence. Many indigenous philosophers have treated phenomenology and its American cousin pragmatism in approving ways. Indeed, the ideas of North America’s first inhabitants seem to have been absorbed by pragmatists and even earlier by transcendentalists like Ralph Waldo Emerson (1803-1882) and Henry David Thoreau (1817-1862). -/- These different philosophies all advance a place-based psychology. Anne Waters, herself of mixed tribal heritage, generalizes the mindset of her people this way: “American Indian consciousness, and hence American Indian identity is … interdependent with our land base.” Lee Hester, a Choctaw thinker, adds that practices—not mere beliefs—are most important for native thought. American transcendentalists and pragmatists, as well as European phenomenologists, similarly see hands-on practices and environmental interactions as the core of experience. Extending this a little, they sometimes suggest experience isn’t individual but instead cultural. “Culture” is here understood as interactions within communities that define our worlds and experiences, as when we talk about the “French experience,” “culture” or “world,” or the “experience of parenthood.” This theme also shows up in indigenous thought. -/- Exploring the Dune universe, we find everything from land-based concepts of personal identity, to the idea of sharpening the mind through hands-on training, to collective notions of experience in cooperative tribes or through the genetic memory of central characters. The stories explore fate versus free will in cosmic contexts, introducing views from indigenous thought and the pragmatic philosophy of William James (1842-1910). Different forms of spiritualism mingle to shape minds and cultural mixtures around the globe, and the same occurs in the Dune series. The customs and personalities of characters fuse elements from Buddhism, Christianity, Hinduism, Judaism, Taoism, and especially Islam. The series not only highlights that religion shapes psychology, but also that faith connects to place, especially paralleling Judeo-Christian-Islamic desert faiths. In capturing these points, the Dune novels show that “our values, our lifestyles and even the ways we think and feel have been strongly influenced by our locations in history and geography. The study of the human mind is fundamentally the study of place.”. (shrink)

In his article, ‘Recovering Humanity: Movement, Sport, and Nature’, Doug Anderson addresses the place of endurance sport, or more generally sport at large, as a potential catalyst for the good life. Anderson contrasts transcendental themes of Henry David Thoreau and Ralph Waldo Emerson with the pragmatic claims of William James and John Dewey, who focus on human possibility and growth. Our aim is to pursue the pragmatic line of thought championed by James and Dewey as a contrasting but not (...) mutually exclusive motive to Anderson’s analysis. We contend that movement can provide humanizing possibilities even more pronounced for those subscribing to pragmatic themes (i.e., growth and the strenuous mood). We will use running and cycling to demonstrate how the strenuous mood enhances the possibility for this humanizing condition. Specifically, we argue that moving in a committed fashion allows us to deepen our relationship with the respective practice and thus opens the possibilities for ‘recovering our humanity’. (shrink)

The generalizability crisis is compounded, or even partially caused, by a lack of specificity in psychological theories. Expanding the use of mechanistic models among psychologists is therefore important, but faces numerous hurdles. A cultural evolutionary approach can help guide and evaluate interventions to improve modeling efforts in psychology, such as developing standards and implementing them at the institutional level.

For many decades, researchers have explored the true potential of human achievement. The expertise field has come a long way since the early works of de Groot (1965) and Chase and Simon (1973). Since then, this inquiry has expanded into the areas of music, science, technology, sport, academia and art. Despite the vast amount of research to date, the capability of study methodologies to truly capture the nature of expertise remains questionable. Some considerations include (i) the individual bias in the (...) retrospective recall of developmental activities, (ii) the ability to develop ecologically valid tasks, and (iii) difficulties capturing the influence of confounding factors on expertise. This article proposes that expertise research in electronic sports (esports) presents an opportunity to overcome some of these considerations. Esports involves individuals or teams of players that compete in video game competitions via human-computer interaction. Advantages of applying the expert performance approach in esports include (i) developmental activities are objectively tracked and automatically logged online, (ii) the constraints of representative tasks correspond with the real-world environment of esports performance, and (iii) expertise has emerged without the influence of guided systematic training environments. Therefore, this article argues that esports research provides an ideal opportunity to further advance research on the development and assessment of human expertise. (shrink)

During the nineteenth and early twentieth centuries, a wide variety of American writers proposed the existence of energies connecting human beings to cosmic processes. From varying points of view--scientific, philosophical, religious, and literary--they suggested that such energies would eventually result in the perfection of individual and collective bodies, assuming that assimilation into larger networks of being meant the expansion of humanity's powers and potentialities--a belief that continues to inform much posthumanist theory today. Universes without Us explores a lesser-known countertradition in (...) American literature. As Matthew A. Taylor's incisive readings reveal, the heterodox cosmologies of Edgar Allan Poe, Henry Adams, Charles Chesnutt, and Zora Neale Hurston reject the anthropocentric fantasy that sees the universe as a kind of reservoir of self-realization. For these authors, the world can be made neither "other" nor "mirror." Instead, humans are enmeshed with "alien" processes that are both constitutive and destructive of "us." By envisioning universes no longer our own, these cosmologies picture a form of interconnectedness that denies any human ability to master it. Universes without Us demonstrates how the questions, possibilities, and dangers raised by the posthuman appeared nearly two centuries ago. Taylor finds in these works an untimely engagement with posthumanism, particularly in their imagining of universes in which humans are only one category of heterogeneous thing in a vast array of species, objects, and forces. He shows how posthumanist theory can illuminate American literary texts and how those texts might, in turn, prompt a reassessment of posthumanist theory. By understanding the posthuman as a materialist cosmology rather than a technological innovation, Taylor extends the range of thinkers who can be included in contemporary conversations about the posthuman.

What is the relationship between lying, belief, and knowledge? Prominent accounts of lying define it in terms of belief, namely telling someone something one believes to be false, often with the intent to deceive. This paper develops a novel account of lying by deriving evaluative dimensions of responsibility from the knowledge norm of assertion. Lies are best understood as special cases of vicious assertion; lying is the anti-paradigm of proper assertion. This enables an account of lying in terms of knowledge: (...) roughly, lying is telling someone something you know ain't so. (shrink)

A great deal of ink has been spilt debating the relative merits of foundationalism and coherentism in contemporary epistemology. In this dissertation, I argue that the debate itself, lively as it's been, rides atop a fundamental mistake. Careful examination of the defenses of these views indicates that both sides rest on a set of problematic presuppositions about justification and the nature of mind. More specifically, they all assume, in one form or another, that epistemic dependence must be inferential, and, as (...) a result, that direct access to the world could only be understood as resting on a class of entities which asymmetrically convey justification to other beliefs without receiving support from them. Revealing these assumptions promises to show that there is a much larger range of options for explaining our knowledge of the world than we can see when we are in the grips of an approach to epistemology and the philosophy of mind which requires us to choose between foundationalism and coherentism.

In the processing of subject-verb agreement, non-subject plural nouns following a singular subject sometimes “attract” the agreement with the verb, despite not being grammatically licensed to do so. This phenomenon generates agreement errors in production and an increased tendency to fail to notice such errors in comprehension, thereby providing a window into the representation of grammatical number in working memory during sentence processing. Research in this topic, however, is primarily done in related languages with similar agreement systems. In order to (...) increase the cross-linguistic coverage of the processing of agreement, we conducted a self-paced reading study in Modern Standard Arabic. We report robust agreement attraction errors in relative clauses, a configuration not particularly conducive to the generation of such errors for all possible lexicalizations. In particular, we examined the speed with which readers retrieve a subject controller for both grammatical and ungrammatical agreeing verbs in sentences where verbs are preceded by two NPs, one of which is a local non-subject NP that can act as a distractor for the successful resolution of subject-verb agreement. Our results suggest that the frequency of errors is modulated by the kind of plural formation strategy used on the attractor noun: nouns which form plurals by suffixation condition high rates of attraction, whereas nouns which form their plurals by internal vowel change (ablaut) generate lower rates of errors and reading-time attraction effects of smaller magnitudes. Furthermore, we show some evidence that these agreement attraction effects are mostly contained in the right tail of reaction time distributions. We also present modeling data in the ACT-R framework which supports a view of these ablauting patterns wherein they are differentially specified for number and evaluate the consequences of possible representations for theories of grammar and parsing.

Juslin & Vll's (J&V's) discussions of evaluative conditioning and episodic memory focus on circumstances in which music becomes associated with arbitrary life events. However, analyses of film music suggest that viewers experience consistent pairings between types of music and types of narrative content. Researchers have demonstrated that the emotional content of film music has a major impact on viewers' emotional experiences of a narrative.

Human music and language are two systems of communication and expression that, while historically considered to overlap, have become increasingly divergent in their approach and study. Music and language almost certainly co-evolved and emerged from the same semiotic field, and this relationship as well as co-origin are actively researched and debated. For the sake of evaluating the semiotic content of zoomusicology, we investigate music from a ‘bottom-up’ biosemiotic functionalist account considering iconic, indexical, and symbolic forms of meaning not in a (...) hierarchy but according to their effects on agents. Such an approach avoids overintellectualizing the representational aspects of music, and instead inverts, as it were, the traditional hierarchy of semiotic categories to produce illocutionary effects. Understanding aesthetics and action not as a priori separate but rather fundamentally co-arising elements of the same events. The focus of musicality again returns to interpretation and how semiosis precipitates expression. (shrink)

This article reflects on the relative silence of African farmers within debates around the potential for genetically modified crops to transform agriculture on the continent. It proposes two strategies for amplifying these voices—one focused on research methodologies, the other on outreach—in order to transform the conversation around GM’s potential in Africa into one that revolves around farmer preferences and priorities.

Artificial moral agents raise complex ethical questions both in terms of the potential decisions they may make as well as the inputs that create their cognitive architecture. There are multiple differences between human and artificial cognition which create potential barriers for artificial moral agency, at least as understood anthropocentrically and it is unclear that artificial moral agents should emulate human cognition and decision-making. It is conceptually possible for artificial moral agency to emerge that reflects alternative ethical methodologies without creating ontological (...) challenges or existential crises for human moral agents.

I explicate and defend Kant's analysis of “skepticism” as a single, metaphilosophically unified rational phenomenon (at A756–764/B784–797, for instance). Kant anticipates one of the defining trends of contemporary epistemology's approach to radical philosophical skepticism: the thought that skepticism cannot be directly refuted, by demonstrating its falsity, but must be diagnosed, to show that its premises are unnatural, and consequently fail to be rationally compelling from within our own nonskeptical standpoint. Kant's most ambitious claim here is that he will develop this (...) diagnosis in a unitary fashion, by demonstrating that Cartesian, Humean, Pyrrhonian, and Agrippan skepticism are essentially interrelated as so many means to “the skeptic's” defining philosophical end. This “unity thesis” comes in both weak and strong variations. First, and more weakly, Kant argues that apparently distinct skeptical problematics share certain crucial metaphilosophical assumptions about the nature of reason, and the role of philosophical self-knowledge. More strongly, he also claims that the four problematics just mentioned are related hierarchically, in that the more fundamental skeptical worries constitute the essential dialectical context for the less fundamental ones, such that the more superficial problematics only arise if a logically prior worry is first acceded to. By showing how deeply these two unity theses structure Kant's Critical methodology, I argue that the Kantian view of philosophy as a “doctrine of wisdom” incorporates, and arguably surpasses, a number of key insights found in more recent work. The final result is that the transcendental philosopher may hope to co-opt the attractions of skepticism without making any unnecessary concessions along the way. (shrink)

Training in the responsible conduct of research (RCR) is required for many research trainees nationwide, but little is known about its effectiveness. For a preliminary assessment of the effectiveness of a short-term course in RCR, medical students participating in an NIH-funded summer research program at the University of California, San Diego (UCSD) were surveyed using an instrument developed through focus group discussions. In the summer of 2003, surveys were administered before and after a short-term RCR course, as well as to (...) alumni of the courses given in the summers of 2002 and 2001. Survey responses were analyzed in the areas of knowledge, ethical decision-making skills, attitudes about responsible conduct of research, and frequency of discussions about RCR outside of class. The only statistically significant improvement associated with the course was an increase in knowledge, while there was a non-significant tendency toward improvements in ethical decision-making skills and attitudes about the importance of RCR training. The nominal impact of a short-term training course should not be surprising, but it does raise the possibility that other options for delivering information only, such as an Internet-based tutorial, might be considered as comparable alternatives when longer courses are not possible.

ABSTRACT In this paper we report the development of a scale measuring Christian ethical beliefs. Three studies refined the Christian Ethical Beliefs Scale from 63 expert-generated potential items. Studies 1 and 3 sampled undergraduate students at private, Christian colleges, and Study 2 utilized a diverse, online sample. Participants responded to an electronic survey of Likert scale items and demographic questions. Following careful assessment of reliability and validity, we present a 20-item scale divided across five factors: Divine Moral Authority, Privacy of (...) Faith, Moral Individualism, Cognition Essential to Personhood, and Value of all Human Beings. This brief scale offers a new way to measure ethical beliefs in religious or nonreligious populations.
