Background The intervention reported in this paper was a follow up to an empirical study conducted in Malawi with the aim of assessing trial participants’ understanding of randomisation, double-blinding and placebo use. In the empirical study, the majority of respondents (61.1%; n= 124) obtained low scores (lower than 75%) on understanding of all three concepts under study. Based on these findings, an intervention based on a narrative which included all three concepts and their personal implications was designed. The narrative used (...) daily examples from the field of Agriculture because Malawi has an agro-based economy. Methods The intervention was tested using a sample of 36 women who had been identified as low scorers during the empirical study. The 36 low scorers were randomly assigned to control (n=18) and intervention arms ( n =18). The control arm went through a session in which they were provided with standard informed consent information for the microbicide trial. The intervention arm went through a session in which they were provided with a narrative in ChiChewa, the local language, with the assistance of a power point presentation which included pictures as well as discussions on justification and personal implications of the concepts under study. Results The findings on the efficacy of the intervention suggest that the 3 scientific concepts and their personal implications can be understood by low literacy populations using simple language and everyday local examples. The findings also suggest that the intervention positively impacted on understanding of trial procedures under study, as 13 of the 18 women in the intervention arm, obtained high scores (above 75%) during the post intervention assessment and none of the 18 in the control arm obtained a high score. Using Fischer’s exact test, it was confirmed that the effect of the intervention on understanding of the three procedures was statistically significant (p=0.0001). Conclusions Potential trial participants can be assisted to understand key clinical trial procedures, their justification and personal implications by using innovative tailored local narratives.

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.

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.

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 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.

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.

I have argued that forgiveness paradigmatically involves overcoming moral anger, of which resentment is the central case. I have argued, as well, that forgiveness may involve overcoming any form of anger so long as the belief that you have been wrongfully harmed is partially constitutive of it, and that overcoming other negative emotions caused by a wrongdoer's misdeed may, given appropriate qualifications, count as forgiveness. Those qualifications indicate, however, significant differences between moral anger and other negative emotions; differences which must (...) be taken into account when determining whether overcoming negative emotions other than moral anger count as forgiveness. I have proposed, too, that forgiveness requires neither overcoming all negative feelings nor the judgment that the offender is a wrongdoer. (shrink)

The value of biodiversity is usually confused with the value of biological resources, both actual and potential. A sharp distinction between biological resources and biodiversity offers a clearer insight into the value of biodiversity itself and therefore the need to preserve it. Biodiversity can be defined abstractly as the differences among biological entities. Using this definition, biodiversity can be seen more appropriately as: (a) a necessary precondition for the long term maintenance of biological resources, and therefore, (b) an essential environmental (...) condition. Three values of biodiversity are identified and arranged in a hierarchy: (1) the self-augmenting phenomenon of biodiversity maintains (2) the conditions necessary for the adaptive evolution of species and higher taxa, which in turn is necessary for providing humans with (3) a range of biological resources in the long term. Two broad policy implications emerge: increments of biodiversity should not be traded off against biological resources as if they were the same, and the conservation of biodiversity should be a constraint on the public interest, not a goal in service of the public interest.

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.

Theories of content purport to explain, among other things, in virtue of what beliefs have the truth conditions they do have. The desire for such a theory has many sources, but prominent among them are two puzzling facts that are notoriously difficult to explain: beliefs can be false, and there are normative constraints on the formation of beliefs.2 If we knew in virtue of what beliefs had truth conditions, we would be better positioned to explain how it is possible for (...) an agent to believe that which is not the case. Moreover, we do not say merely of such an agent that he believes that p when p is not the case. We say the agent made a mistake, and often criticize him accordingly; we think agents ought not have false beliefs, and that such beliefs should be changed; etc. An adequate theory of content would, presumably, reveal the source of these normative facts about the mental lives of agents. Indeed, it is typically taken to be an adequacy constraint on a theory of content that it help explain the possibility of error and the "normativity" of content. Teleological theories of content promise to do just this. (shrink)

The predominant function of Australian clinical ethics committees (CECs) is policy formation. Some committees have an educational role. Few committees play any direct role in advising on ethics in the management of individual patients and this occurs only in exceptional circumstances. There is a tendency to exaggerate both the number and function of committees. It is suggested that studies of ethics committees, based on questionnaire surveys, should be interpreted cautiously. An examination of ethical issues indicates that there is a role (...) for a critical analysis of power relations in Australian hospitals that is not fulfilled by CECs. (shrink)

A study of how syntax relates to meaning by a leader of the new generation of philosopher-linguists.

The identity theory was called into doubt not because the prospects for a materialist account of our mental capacities were thought to be poor, but because it seemed unlikely that the arrival of an adequate materialist theory would bring with it the nice one-to-one match-ups, between the concepts of folk psychology and the concepts of theoretical neuroscience, that intertheoretic reduction requires. The reason for that doubt was the great variety of quite different physical systems that could instantiate the required functional (...) organization. Eliminative materialism also doubts that the correct neuroscientific account of human capacities will produce a neat reduction of our common-sense framework, but here the doubts arise from a quite different source.

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)

The Mind-Body Problem Questions: What is the mind? What is its connection to the body? Most basic division of answers: Dualist and Materialist (or Physicalist) responses.

In a recent paper, Bar-On and Risjord (henceforth, 'B&R') contend that Davidson provides no 1 good argument for his (in)famous claim that "there is no such thing as a language." And according to B&R, if Davidson had established his "no language" thesis, he would thereby have provided a decisive reason for abandoning the project he has long advocated--viz., that of trying to provide theories of meaning for natural languages by providing recursive theories of truth for such languages. For he would (...) have shown that there are no languages to provide truth (or meaning) theories of. Davidson thus seems to be in the odd position of arguing badly for a claim that would undermine his own work. (shrink)

In this comment on Yli-Vakkuri and Hawthorne's illuminating book, Narrow Content, I address some issues related to externalist conceptions of linguistic meaning.

Proactive law enforcement techniques such as sting operations sometimes go too far, resulting in innocent people being "entrapped" into committing crime. Fortunately, the criminal law recognizes entrapment as a defense to a criminal charge. There is, however, much confusion about entrapment. In this paper I argue that this confusion is a result of misunderstanding the _moral status of entrapment. Since all proactive law enforcement violates the autonomy of those subject to it, it undermines moral agency and criminal liability. Although this (...) is sometimes justifiable, proactive law enforcement that does so in a way that constitutes entrapment is not. (shrink)

An updated version of Plato's Dialogues, this adaptation takes place in contemporary times and is set at Reed College in Portland, Oregon. Through the characters' central discussions of Creationist and Materialist theories of evolution, together with their moral and social implications and ramifications, the author defines philosophy and science. This fresh approach to complex philosophical subjects will be an interesting supplement to courses in philosophy.

Functionalism in the philosophy of mind is here criticized from the perspective of a more naturalistic and less compromising form of materialism. Parallels are explored between the problem of cognitive activity and the somewhat more settled problem of vital activity. The lessons drawn suggest that functionalism in the philosophy of mind may be both counterproductive as a research strategy, and false as a substantive position.

The event analysis of action sentences seems to be at odds with plausible (Davidsonian) views about how to count actions. If Booth pulled a certain trigger, and thereby shot Lincoln, there is good reason for identifying Booths' action of pulling the trigger with his action of shooting Lincoln; but given truth conditions of certain sentences involving adjuncts, the event analysis requires that the pulling and the shooting be distinct events. So I propose that event sortals like 'shooting' and 'pulling' are (...) true of complex events that have actions (and various effects of actions) as parts. Combining this view with some facts about so-called causative verbs, I then argue that paradigmatic actions are best viewed as tryings, where tryings are taken to be intentionally characterized events that typically cause peripheral bodily motions. The proposal turns on a certain conception of what it is to be the Agent of an event; and I conclude by elaborating this conception in the context of some recent discussions about the relation of thematic roles to grammatical categories.

In this book, Livingston develops the political implications of formal results obtained over the course of the twentieth century in set theory, metalogic, and computational theory. He argues that the results achieved by thinkers such as Cantor, Russell, Godel, Turing, and Cohen, even when they suggest inherent paradoxes and limitations to the structuring capacities of language or symbolic thought, have far-reaching implications for understanding the nature of political communities and their development and transformation. Alain Badiou's analysis of logical-mathematical structures forms (...) the backbone of his comprehensive and provocative theory of ontology, politics, and the possibilities of radical change. Through interpretive readings of Badiou's work as well as the texts of Giorgio Agamben, Jacques Lacan, Jacques Derrida, Gilles Deleuze, and Ludwig Wittgenstein, Livingston develops a formally based taxonomy of critical positions on the nature and structure of political communities. These readings, along with readings of Parmenides and Plato, show how the formal results can transfigure two interrelated and ancient problems of the One and the Many: the problem of the relationship of a Form or Idea to the many of its participants, and the problem of the relationship of a social whole to its many constituents.

It is argued that two aspects of the progress of mature science characterize, at least in combination, no other fields; hence, that these aspects can usefully serve as a demarcation criterion. Scientific progress is: (1) cumulative, regardless of crisis or revolution, from the viewpoint of concrete applications; (2) capable of unrestricted growth towards universal coerciveness of argument and evidence. Before these aspects of progress are discussed, some clarifications are made and corrections offered to Kuhn's view of the nature of scientific (...) progress across revolutions; afterwards, the suggested criterion is used to distinguish, concretely, various fields from science. Finally, it is shown that the "style" of scientific progress is not a useful demarcation criterion. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Buddhist CarolPaul M. KeelingI will live in the Past, the Present, and the Future! The Spirits of all Three shall strive within me.—Scrooge on Christmas DayTo the Buddhas of the past, present and all future time... I will prostrate and bow.—ŚāntidēvaCharles Dickens's A Christmas Carol is one of the greatest tales of human redemption known in the Western world. As a child I heard it read aloud every (...) Christmas, and there was always a thrilling magic to rehearing the story of Scrooge's moving spiritual transformation. Yet, the story raises an important spiritual question: Scrooge is a new man on Christmas day, but what about after that? We often vow to be better people and fail. Why is this? A Christmas Carol is, of course, pure fantasy—a deeply heartwarming fantasy that bears repeated hearings—but it nonetheless does raise a real question about how spiritual enlightenment is actually achieved.I still appreciate A Christmas Carol as much as I did when I was a child, but as I have grown older, and after having encountered Buddhist philosophy, I have also begun to contemplate the story of Scrooge's spiritual transformation in a new light. The Buddhist notion of karma entails that, even if we are deeply moved now to change our ways for the better, the unexamined patterns of thought that underpinned our past actions retain a latent force in our mind stream that can influence us unexpectedly. If we are not observant of these patterns of thought, we are likely to repeat the kinds of actions we have performed in the past. Because the force of karma can be very strong, "overnight" spiritual and moral transformations are comparatively rare. On a Buddhist reading, the end of A Christmas Carol is where the spiritual journey for Scrooge actually begins.This underestimation of the force of karma on Dickens's part was, of course, a necessary case of artistic license, but is somewhat conspicuous given that a realization of the law of karma plays a critical (albeit unnamed) role in the story of Scrooge's putative enlightenment. Scrooge's transformation begins with a visit from the ghost [End Page 25] of his deceased business partner, Jacob Marley, a man who was as miserly and selfish as Scrooge himself. Marley's ghost is weighed down by a heavy chain, which represents his regret for having lived such a greedy and shortsighted life. "I wear the chain I forged in life. I made it link by link, yard by yard: I girded it on my own free will, and of my own free will I wore it."1 He warns that Scrooge will be visited by three spirits whose lessons he must heed in order to redeem himself. "Without their visits," Marley declares, "you cannot hope to shun the path I tread."2 Upon Marley's departure we are then treated to a Dickensian image of the Buddhist "lower realms." Scrooge looks out the window into the cold night air and sees a swarm of unfortunate ghostly forms, suffering and encumbered by heavy chains of remorse: "The air was filled with phantoms, wandering hither and thither in restless haste, and moaning as they went.... The misery with them all was, clearly, that they sought to interfere, for good, in human matters, and had lost this power for ever."3 Later, Scrooge's nephew Fred makes this pithy karmic observation: "Scrooge's offences carry their own punishment.... Who suffers by his ill whims? Himself, always."4Throughout the remainder of the night Scrooge is visited sequentially by the three spirits representing the Christmases past, present, and future, who, like helpful bodhisattvas, show him scenes from his life in order to awaken him to a realization of the law of karma. By the Ghost of Christmas Past Scrooge is presented with painful images of his childhood suffering as well as the kindness shown to him by others in the past, and learns how the present direction of his life has been shaped by these experiences. The Ghost of Christmas Present reminds Scrooge of the precious opportunities all around him to do good by his fellow... (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)

I argue that linguistic meanings are instructions to build monadic concepts that lie between lexicalizable concepts and truth-evaluable judgments. In acquiring words, humans use concepts of various adicities to introduce concepts that can be fetched and systematically combined via certain conjunctive operations, which require monadic inputs. These concepts do not have Tarskian satisfaction conditions. But they provide bases for refinements and elaborations that can yield truth-evaluable judgments. Constructing mental sentences that are true or false requires cognitive work, not just an (...) exercise of basic linguistic capacities. (shrink)

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)

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.

It is argued herein that there are two distinct ways in which all observation vocabularies are prejudiced with respect to theory. An argument based on the demands of adequate translation is invoked to show that even the simplest of our observation predicates must display the first and more obvious grade of bias--intensional bias. It is also argued that any observation vocabulary whose predicates are corrigibly applicable must manifest a second and equally serious grade of bias--extensional bias--independently of whatever intensional bias (...) its predicates may or may not have.

The doctrine that the character of our perceptual knowledge is plastic, and can vary substantially with the theories embraced by the perceiver, has been criticized in a recent paper by Fodor. His arguments are based on certain experimental facts and theoretical approaches in cognitive psychology.
