A study in the philosophy of science, proposing a strong form of the doctrine of scientific realism' and developing its implications for issues in the philosophy of mind.

Paul M. Pietroski presents an ambitious new account of human languages as generative procedures that respect substantive constraints. He argues that meanings are neither concepts nor extensions, and sentences do not have truth conditions; meanings are composable instructions for how to access and assemble concepts of a special sort.

The problem of explaining consciousness remains a problem about the meaning of language: the ordinary language of consciousness in which we define and express our sensations, thoughts, dreams and memories. This book argues that the problem arises from a quest that has taken shape over the twentieth century, and that the analysis of history provides new resources for understanding and resolving it. Paul Livingston traces the development of the characteristic practices of analytic philosophy to problems about the relationship of (...) experience to linguistic meaning, focusing on the theories of such philosophers as Carnap, Schlick, Neurath, Husserl, Ryle, Putnam, Fodor and Wittgenstein. Clearly written and avoiding technicalities, this book will be eagerly sought out by professionals and graduate students in philosophy and cognitive science. (shrink)

In _ Plato's Camera_, eminent philosopher Paul Churchland offers a novel account of how the brain constructs a representation -- or "takes a picture" -- of the universe's timeless categorical and dynamical structure. This construction process, which begins at birth, yields the enduring background conceptual framework with which we will interpret our sensory experience for the rest of our lives. But, as even Plato knew, to make singular perceptual judgments requires that we possess an antecedent framework of abstract categories (...) to which any perceived particular can be relevantly assimilated. How that background framework is assembled in the first place is the motivating mystery, and the primary target, of Churchland's book. Unexpectedly, this neurobiologically grounded account of human cognition also provides a systematic story of how such low-level epistemological activities are integrated within an enveloping framework of linguistic structures and regulatory mechanisms at the social level. As Churchland illustrates, this integration of cognitive mechanisms at several levels has launched the human race on an epistemological adventure denied to all other terrestrial creatures. (shrink)

In recent years there has been substantial support for heart rate variability biofeedback (HRVB) as a treatment for a variety of disorders and for performance enhancement ( Gevirtz, 2013 ). Since conditions as widely varied as asthma and depression seem to respond to this form of cardiorespiratory feedback training, the issue of possible mechanisms becomes more salient. The most supported possible mechanism is the strengthening of homeostasis in the baroreceptor ( Vaschillo et al., 2002 ; Lehrer et al., 2003 ). (...) Recently, the effect on the vagal afferent pathway to the frontal cortical areas has been proposed. In this article, we review these and other possible mechanisms that might explain the positive effects of HRVB. (shrink)

Paul Pietroski presents an original philosophical theory of actions and their mental causes. We often act for reasons: we deliberate and choose among options, based on our beliefs and desires. However, bodily motions always have biochemical causes, so it can seem that thinking and acting are biochemical processes. Pietroski argues that thoughts and deeds are in fact distinct from, though dependent on, underlying biochemical processes within persons.

In the Logic of Being: Realism, Truth, and Time, the influential philosopher Paul M. Livingston explores and illuminates truth, time, and their relationship by employing methods from both Continental and analytic philosophy.

Eliminative materialism is the thesis that our common-sense conception of psychological phenomena constitutes a radically false theory, a theory so fundamentally defective that both the principles and the ontology of that theory will eventually be displaced, rather than smoothly reduced, by completed neuroscience. Our mutual understanding and even our introspection may then be reconstituted within the conceptual framework of completed neuroscience, a theory we may expect to be more powerful by far than the common-sense psychology it displaces, and more substantially (...) integrated within physical science generally. My purpose in this paper is to explore these projections, especially as they bear on (1) the principal elements of common-sense psychology: the propositional attitudes (beliefs, desires, etc.), and (2) the conception of rationality in which these elements figure.

Paul M. Pietroski, University of Maryland I had heard it said that Chomsky’s conception of language is at odds with the truth-conditional program in semantics. Some of my friends said it so often that the point—or at least a point—finally sunk in.

This paper expounds that besides the well-known spatio-temporal problem there is a causal problem of entanglement: even when one neglects spatio-temporal constraints, the peculiar statistics of EPR/B experiment is inconsistent with usual principles of causal explanation as stated by the theory of causal Bayes nets. The conflict amounts to a dilemma that either there are uncaused correlations or there are caused independences . I argue that the central ideas of causal explanations can be saved if one accepts the latter horn (...) and explains the unfaithful independences by a stable fine-tuning of the causal parameters.

The assignment events, objects, state of beings, etc., to an experiential category is a fundamental activity carried out by human (and by other animals). So rudimentary are the processes involved in categorizing that it is indeed impossible to imagine conscious awareness to exist without the presence of categories. A considerable body of writing exists on categories dating from the times of Classical philosophy. Plato developed a categorical ontology and Aristotle produced one of the earliest examples of a complex understanding of (...) basic ontologies. A number of other categorially structured ontologies have been proposed including those by Lowe, Westerhoff, Chisholm, etc. The book is an edited collection of up to the moment essays that address critical aspects on the understanding of categories and categorial systems. The perspectives included in the book are drawn from philosophy, psychology, theology, divinity, comparative cognition and facet theory. The authors are all renowned experts in the area of their writing. Topics addressed include both contemporary advances in the understanding of perennial debates and latest thinking upon how categories are employed to structure our experiences of the world we live in. The book is distinct as being written by philosophers and psychologists. The book is a collection of writings from selected academics at the fore of debates and understandings of categories in contemporary thought. The text provides a single source for contemporary scholarship in categories. No single text that brings together expositions of categorial experiences for students and academics within the above listed disciplines. (shrink)

Davidsonian analyses of action reports like ‘Alvin chased Theodore around a tree’ are often viewed as supporting the hypothesis that sentences of a human language H have truth conditions that can be specified by a Tarski-style theory of truth for H. But in my view, simple cases of adverbial modification add to the reasons for rejecting this hypothesis, even though Davidson rightly diagnosed many implications involving adverbs as cases of conjunct-reduction in the scope of an existential quantifier. I think the (...) puzzles in this vicinity reflect “framing effects,” which reveal the implausibility of certain assumptions about how linguistic meaning is related to truth and logical form. We need to replace these assumptions with alternatives, instead of positing implausible values of event-variables or implausible relativizations of truth to linguistic descriptions of actual events.

During mammalian fertilization sperm bind to the egg's zona pellucida (ZP) after undergoing capacitation. Capacitated mouse sperm bind to mZP3 (one of three ZP glycoproteins), undergo the acrosome reaction, penetrate the ZP, and fuse with egg plasma membrane. Sperm protein 56 (sp56), a member of the C3/C4 superfamily of binding proteins, was identified nearly 20 years ago as a binding partner for mZP3 by photoaffinity cross‐linking of acrosome‐intact sperm. However, subsequent research revealed that sp56 is a component of the sperm's (...) acrosomal matrix and, for sperm with an intact acrosome, should be unavailable for binding to mZP3. Recently, this dilemma was resolved when it was recognized that some acrosomal matrix (AM) proteins, including sp56, are released to the sperm surface during capacitation. This may explain why uncapacitated mammalian sperm are unable to bind to the unfertilized egg ZP. (shrink)

_Philosophy and the Vision of Language_ explores the history and enduring significance of the twentieth-century turn to language as a specific object of investigation and resource for philosophical reflection. It traces the implications of the access to language in some of the most prominent projects and results of the historical and contemporary tradition of analytic philosophy, including the projects of Frege, Wittgenstein, Sellars, Quine, Brandom, and Cavell. Additionally, it demonstrates the deep and enduring connections between the analytic tradition’s inquiry into (...) language and the parallel inquiries of phenomenology, critical theory, and deconstruction over the course of the twentieth century. Finally, it documents some of the enduring consequences of philosophy’s inquiry into language for contemporary questions of social and political life. The book provides a clear, accessible and widely inclusive introduction to the relevance of language for analytic and continental philosophy in the twentieth century and is readable by non-specialist audiences. It should contribute to a growing historical sense of the location of the analytic tradition in a broader geography of social, political and critical thought. Furthermore, it contributes to building bridges between this tradition and the neighboring continental ones from which it has all too often been estranged. (shrink)

In this paper I critically discuss what has come to be known as the consensus or standard view of interpersonal forgiveness noting some of the paradoxes it appears to generate, how its conceptual resources seem unable to help illuminate several other varieties of forgiveness that are either themselves instances of interpersonal forgiving or at least types of forgiveness that a theory of interpersonal forgiveness should be able to shed some light upon. In the final section I offer some remarks on (...) the nature of revenge, which has recently come to be seen by some philosophers as a morally acceptable alternative to forgiving wrongdoers, note some of the puzzles to which it gives rise, and conclude that while both types of responses to wrongdoers remain morally complex, there is good reason to think that forgiveness is the morally more appropriate response to having been wronged.

_ Source: _Volume 94, Issue 3, pp 301 - 331 The idea that we can understand key aspects of the metaphysics of consciousness by understanding conscious states as having a _presentational_ character plays an essential role in the phenomenological tradition beginning with Brentano and Husserl. In this paper, the author explores some potential consequences of this connection for contemporary discussions of the ontology of consciousness in the world. Drawing on Hintikka’s analysis of epistemic modality, the author argues that the essential (...) presentational character of consciousness can be seen as accounting for the familiar failure of substitutivity of identicals in intensional contexts of conscious presentation and further provides for an ontology of conscious presentation that avoids metaphysically problematic commitments to “special” intentional objects. The author next considers how the irreducibility of intensional contexts, if grounded in the presentational character of consciousness, also may provide for a kind of irreducibility of the “first-person” perspective to third-person or objective description across possible worlds. Finally, drawing on Chalmers’ “two-dimensionalist” semantic framework, the author argues that attention to the presentational aspect of consciousness as thus understood, while it provides significant motivation for the existence of the “hard problem” of the irreducibility of consciousness to physical and structural description, is nevertheless consistent with a globally monist, rather than dualist, ontology.

For the uninitiated, there are two major tendencies in the modeling of human cognition. The older, tradtional school believes, in essence, that full human cognition can be modeled by dividing the world up into distinct entities -- called __symbol s__-- such as “dog”, “cat”, “run”, “bite”, “happy”, “tumbleweed”, and so on, and then manipulating this vast set of symbols by a very complex and very subtle set of rules. The opposing school claims that this system, while it might be good (...) at concluding that Paris is the capital of France or that there must be blood flowing in the left-rear leg of a cow, can never capture the full measure -- indeed, the essence -- of human cognition. For them, the essential features of cognition emerge from the combined effects of myriad, tiny actions far below the surface of consciousness. This is the camp to which Paul Churchland belongs.

In _Matter and Consciousness_, Paul Churchland presents a concise and contemporary overview of the philosophical issues surrounding the mind and explains the main theories and philosophical positions that have been proposed to solve them. Making the case for the relevance of theoretical and experimental results in neuroscience, cognitive science, and artificial intelligence for the philosophy of mind, Churchland reviews current developments in the cognitive sciences and offers a clear and accessible account of the connections to philosophy of mind. For (...) this third edition, the text has been updated and revised throughout. The changes range from references to the iPhone's "Siri" to expanded discussions of the work of such contemporary philosophers as David Chalmers, John Searle, and Thomas Nagel. Churchland describes new research in evolution, genetics, and visual neuroscience, among other areas, arguing that the philosophical significance of these new findings lies in the support they tend to give to the reductive and eliminative versions of materialism. Matter and Consciousness, written by the most distinguished theorist and commentator in the field, offers an authoritative summary and sourcebook for issues in philosophy of mind. It is suitable for use as an introductory undergraduate text. (shrink)

Electronic health record (EHRs) have largely replaced obsolete paper medical charts. This replacement has produced an increased demand on physicians’ time and has compromised efficiency. In an attempt to overcome this perceived obstacle to productivity, physicians turned to medical scribes to perform the work required by EHRs. In doing so, they have introduced an uninvited participant in the physician-patient relationship and compromised patients’ confidentiality. Scribes may be a successful work around for physicians frustrated by EHRs, but patients’ confidentiality should not (...) be sacrificed in the process. (shrink)
