When we reach to pick up an object, our actions are effortlessly informed by the object’s spatial information, the position of our limbs, stored knowledge of the object’s material properties, and what we want to do with the object. A substantial body of evidence suggests that grasps are under the control of “automatic, unconscious” sensorimotor modules housed in the “dorsal stream” of the posterior parietal cortex. Visual online feedback has a strong effect on the hand’s in-flight grasp aperture. Previous work (...) of ours exploited this effect to show that grasps are refractory to cued expectations for visual feedback. Nonetheless, when we reach out to pretend to grasp an object (pantomime grasp), our actions are performed with greater cognitive effort and they engage structures outside of the dorsal stream, including the ventral stream. Here we ask whether our previous finding would extend to cued expectations for haptic feedback. Our method involved a mirror apparatus that allowed participants to see a “virtual” target cylinder as a reflection in the mirror at the start of all trials. On “haptic feedback” trials, participants reached behind the mirror to grasp a size-matched cylinder, spatially coincident with the virtual one. On “no-haptic feedback” trials, participants reached behind the mirror and grasped into “thin air” because no cylinder was present. To manipulate haptic expectation, we organized the haptic conditions into blocked, alternating, and randomized schedules with and without verbal cues about the availability of haptic feedback. Replicating earlier work, we found the strongest haptic effects with the blocked schedules and the weakest effects in the randomized uncued schedule. Crucially, the haptic effects in the cued randomized schedule was intermediate. An analysis of the influence of the upcoming and immediately preceding haptic feedback condition in the cued and uncued random schedules showed that cuing the upcoming haptic condition shifted the haptic influence on grip aperture from the immediately preceding trial to the upcoming trial. These findings indicate that, unlike cues to the availability of visual feedback, participants take advantage of cues to the availability of haptic feedback, flexibly engaging pantomime, and natural modes of grasping to optimize the movement.

The cogito ergo sum of Descartes is one of the best-known of all philosophical formulations, but ever since it was first propounded it has defied any formal accounting of its validity. How is it that so simple and important an argument has caused such difficulty and such philosophical controversy? In this pioneering work, Jerrold Katz argues that the problem with the cogito lies where it is least suspected--in a deficiency in the theory of language and logic that Cartesian scholars (...) have brought to the study of the cogito. Katz contends that the laws of traditional logic have distorted Descartes's reasoning so that it no longer fits either Descartes's own account of the cogito in his writings or the role he assigns it in his project. Katz proposes that the cogito can be understood as an example of "analytic entailment," a concept in the philosophy of language whereby a statement can be a formally valid inference without depending on a law of logic. Developing and defending his thesis, he shows us that by grappling with an historical philosophical problem it is possible to make an original contribution to the advance of contemporary philosophy.

The study of anarchism as a philosophical, political, and social movement has burgeoned both in the academy and in the global activist community in recent years. Taking advantage of this boom in anarchist scholarship, Nathan J. Jun and Shane Wahl have compiled twenty-six cutting-edge essays on this timely topic in New Perspectives on Anarchism.

Deleuze Connections Series Editor: Ian Buchanan Eleven top Deleuze scholars reclaim Deleuzian philosophy as moral philosophy Ethics plays a crucial, if subtle, role in Gilles Deleuze's philosophical project. Michel Foucault claimed that Anti-Oedipus was `a book of ethics, the first book of ethics to be written in France in quite a long time'. But what is the nature of the immanent ethics that is developed in Deleuze's thought? How does it differ from previous conceptions of ethics? And what paths does (...) it open for future thought, given the ethical challenges facing humanity in so many domains? Each of the eleven essays in this collection explores the ethical dimension of Deleuze's thought along a new and singular trajectory, and in so doing, attempts to reclaim his philosophy as an ethical philosophy.

Although they take different approaches, both Taede A. Smedes and Kevin Sharpe have challenged the theology-and-science enterprise and raised important questions about theological and scientific assumptions behind this work. Smedes argues that theology should be taken more seriously, and Sharpe believes that theology should be more scientific. A proposed middle way involves engaging in the dialogue itself and exploring the questions and methodological implications that arise in the context of problem-focused interactions.

AbstractAgroecosystems in the Midwestern United States are undergoing changes that pressure farmers to adapt their farming practices. Because farmers decide what practices to implement on their land, there are needs to understand how they adapt to competing demands of changes in global markets, technology, farm sizes, and decreasing rural populations. Increased understanding of farmer decision-making can also inform agricultural policy in ways that encourage farmer adoption of sustainable practices. In this research we adopt a grounded view of farmers by interpreting (...) their decision-making through their stories of everyday life. We use a narrative analysis to identify recurrent themes that characterize farmer decisions as active negotiations between the demands of efficiency in maximizing crop yields with a desire to steward land through past, present, and future generations. Together these narratives portray farmer decisions as a place-making process that seeks compatibility among distinct aspirations for their land. (shrink)

_Brill’s Companion to Anarchism and Philosophy_ offers a broad thematic overview of the relationship between anarchism and philosophy.

Over the course of the last four decades, William Leon McBride has distinguished himself as one of the most esteemed and accomplished philosophers of his generation. This volume—which celebrates the occasion of his seventy-fifth birthday—includes contributions from colleagues, friends, and formers students and pays tribute to McBride’s considerable achievements as a teacher, mentor, and scholar.

We address the claim that nonhuman animals do not represent unobservable states, based on studies of physical cognition by rooks and social cognition by scrub-jays. In both cases, the most parsimonious explanation for the results is counter to the reinterpretation hypothesis. We suggest that imagination and prospection can be investigated in animals and included in models of cognitive architecture.

Peter Harrison's Gifford Lectures demonstrate that the modern concepts of “religion” and “science” do not correspond to any fixed sphere of life in the pre-modern world. Because these terms are incommensurate and ideological, they misconstrue the past. I examine the influence and affinities of Ludwig Wittgenstein's philosophy on Harrison's study in order to argue that Harrison's project approaches Wittgenstein's. Harrison's book is a therapeutic history, untying a knot in scholarly language. I encourage Harrison, however, to clarify how future scholars can (...) progress in their study of phenomena once termed “scientific” or “religious” without succumbing to these same mistakes.

Before curing was a possibility, medicine was devoted to the relief of suffering. Attention to the relief of suffering often takes a back seat in modern biomedicine. This book seeks to place suffering at the center of biomedical attention, examining suffering in its biological, psychological, clinical, religious, and ethical dimensions.
