ANGUS J, HODNETT E and O’BRIEN-PALLAS L. Nursing Inquiry 2003; 10: 218–228Implementing evidence-based nursing practice: a tale of two intrapartum nursing unitsDespite concerns that the rise of evidence-based practice threatens to transform nursing practice into a performative exercise disciplined by scientific knowledge, others have found that scientific knowledge is by no means the preeminent source of knowledge within the dynamic settings of health-care. We argue that the contexts within which evidence-based innovations are implemented are as influential in the outcomes (...) as the individual practitioners who attempt these changes. A focused ethnography was done in follow-up to an earlier trial that evaluated the effectiveness of a marketing strategy to encourage the adoption of evidence-based intrapartum nursing practice. Bourdieu's (1990, 1991) concepts of habitus, capital and social field were used in our refinement of the analysis of the ethnographic findings. Nursing leadership, interprofessional struggle with physicians, the characteristics of the community and the physical environment were prominent issues at all of the sites. Detailed descriptions of the sociohistorical context and of the experiences at two sites are presented to illustrate the complexities encountered when implementing innovations. (shrink)

Toward evidence‐based policy decisions: a case study of nursing health human resources in Ontario, CanadaThis paper reflects how health services research ‘evidence’ was used to influence decisions in the province of Ontario, Canada. The process involved interaction among a variety of stakeholders and decision‐makers with researchers to reduce uncertainty and to substantiate emerging service provision issues in the province. The issues presented here focus specifically on an analysis of the nursing situation completed in 1998 for the Minister of Health’s Nursing (...) Task Force, which examined key issues in service delivery. The issues were: restructured work environments; nurse supply and declining enrollments; labour trends and utilization of the nursing workforce; patient acuity and complexity of work environments and the influence on workload; and the paucity of reliable and valid data bases for analysis of nursing’s contribution to the health system. Ontarians can be confident that the Task Force recommendations were born from solid research‐based evidence and now the challenge becomes to monitor the implementation of these resolutions over time.

It has been widely accepted that intentional actions are “the actions to which “a certain sense of the question ‘why?’ is given application” (Anscombe 1957/2000: 9). But there are robust reasons for thinking that this claim is false. First, there are intentional actions for which such questions are unsound. We have good reasons for thinking that the questions are not “given application” in these cases. Second, when these questions are “given application” this is best explained, it is argued, not in (...) terms of a necessary link between intentional action and this type of enquiry, but in terms of the fact that this is an enquiry that we pursue when we take an agent to have exercised certain of their rational capacities.

In chapter 3 of Wild Animal Ethics Johannsen argues for a collective obligation based on beneficence to intervene in nature in order to reduce the suffering of wild animals. In the same chapter he claims that the non-identity problem is merely a “theoretical puzzle” which doesn’t affect our reasons for intervention. In this paper I argue that the non-identity problem affects both the strength and the nature of our reasons to intervene. By intervening in nature on a large scale we (...) change which animals come into existence. In doing so, we enable harmful animals to inflict harms on other animals, and we put other animals in harm’s way. The harms that these animals will inflict and endure are foreseeable. Furthermore, since non-human animals aren’t moral agents, harmful animals cannot be morally responsible for their harmful actions. I argue therefore that by causing animals to exist, knowing that they will inflict and suffer harms, we become morally responsible for those harms. By engaging in identity-affecting actions then we take on secondary moral duties towards the animals we have thereby caused to exist, and these secondary moral duties may be extremely demanding, even more so than the initial costs of intervention. Finally, these duties are duties of justice rather than duties of beneficence, and as such are more stringent than purely beneficence-based moral reasons. Furthermore, this conclusion flows naturally from several plausible principles which Johannsen explicitly endorses. (shrink)

In this paper I want to propose that we see solipsism as arising from certain problems we have about identifying ourselves as subjects in an objective world. The discussion will centre on Wittgenstein’s treatment of solipsism in his Tractatus Logico- Philosophicus. In that work Wittgenstein can be seen to express an unusually profound understanding of the problems faced in trying to give an account of how we, who are subjects, identify ourselves as objects in the world. We have in his (...) compressed remarks, the kernels of a number of arguments which all come together to form what can be called the problem of self-identification. I want to argue that the solipsism of the Tractatus arises at least in part as a solution to, or – to put it less optimistically – as a symptom or articulation of this problem. In approaching Wittgenstein’s early discussion of solipsism in this way I will obviously be in disagreement with some other interpretations of the work. For example, there are those who think that there is no ‘solipsism of the Tractatus’.1 In fact, the Tractarian arguments presented below as motivating solipsism have been seen as fulfilling the quite opposite function of refuting it. I do not intend in this piece to engage with alternative interpretations. Let me say a little bit about why I have granted myself the licence not to do so. First, the focus of my concern with solipsism is on how it connects with what I have called the problem of self-identification. While it is a concern that emerged in an attempt to make sense of Wittgenstein’s remarks in. (shrink)

How is it that we think and refer in the first-person way? For most philosophers in the analytic tradition, the problem is essentially this: how two apparently conflicting kinds of properties can be reconciled and united as properties of the same entity. What is special about the first person has to be reconciled with what is ordinary about it. The range of responses reduces to four basic options. The orthodox view is optimistic: there really is a way of reconciling these (...) apparently contradictory properties as contained within the same thing. The heretical views are pessimistic and content to be so: there is no such way, and that is because there is simply nothing to reconcile – because there is really nothing special about what is in question; or there is really nothing ordinary about it; or there is really nothing ….

The twelve specially written essays in this volume investigate the neglected topic of mental action, and show its importance for the metaphysics, epistemology, and phenomenology of mind. The essays investigate what mental actions are, how we are aware of them, and what is the relationship between mental and physical action.

Although connectionism is advocated by its proponents as an alternative to the classical computational theory of mind, doubts persist about its _computational_ credentials. Our aim is to dispel these doubts by explaining how connectionist networks compute. We first develop a generic account of computation—no easy task, because computation, like almost every other foundational concept in cognitive science, has resisted canonical definition. We opt for a characterisation that does justice to the explanatory role of computation in cognitive science. Next we examine (...) what might be regarded as the “conventional” account of connectionist computation. We show why this account is inadequate and hence fosters the suspicion that connectionist networks aren’t genuinely computational. Lastly, we turn to the principal task of the paper: the development of a more robust portrait of connectionist computation. The basis of this portrait is an explanation of the representational capacities of connection weights, supported by an analysis of the weight configurations of a series of simulated neural networks.

It is commonplace for both philosophers and cognitive scientists to express their allegiance to the "unity of consciousness". This is the claim that a subject’s phenomenal consciousness, at any one moment in time, is a single thing. This view has had a major influence on computational theories of consciousness. In particular, what we call single-track theories dominate the literature, theories which contend that our conscious experience is the result of a single consciousness-making process or mechanism in the brain. We argue (...) that the orthodox view is quite wrong: phenomenal experience is not a unity, in the sense of being a single thing at each instant. It is a multiplicity, an aggregate of phenomenal elements, each of which is the product of a distinct consciousness-making mechanism in the brain. Consequently, cognitive science is in need of a multi-track theory of consciousness; a computational model that acknowledges both the manifold nature of experience, and its distributed neural basis.

Book description: * Seventeen brand-new essays by leading philosophers and psychologists * Genuinely interdisciplinary work, at the forefront of both fields * Includes a valuable introduction, uniting common threads Leading philosophers and psychologists join forces to investigate a set of problems to do with agency and self-awareness, in seventeen specially written essays. In recent years there has been much psychological and neurological work purporting to show that consciousness and self-awareness play no role in causing actions, and indeed to demonstrate that (...) free will is an illusion. The essays in this volume subject the assumptions that motivate such claims to sustained interdisciplinary scrutiny. Patients with Anarchic Hand syndrome sometimes find their hands perform apparently goal-directed actions which the patients disown, yet seem to be unable to suppress (for example, reaching out for someone else's food in a restaurant). On the face of it, these patients lack the kind of control and self-awareness we ordinarily take ourselves to have when acting intentionally. Questions raised by this phenomenon include: What is involved in being aware of an action as one's own? What is the nature of the control these patients are lacking and which characterizes normal intentional actions? What is the relation between a priori explanations of consciousness and self-consciousness, on the one hand, and empirical work on the information-processing mechanisms involved in action control, on the other? Questions of action control and self-awareness tend to be treated separately in both philosophy and psychology. The central idea behind this volume is that outstanding unresolved issues on both topics, and in both disciplines, can only be resolved by an interdisciplinary examination of the relations between them. The editors' useful introductory essay offers a guide to cross-disciplinary reading of the contributions, and makes connections between them explicit. The book will be compulsory reading for psychologists and philosophers working on action explanation, and for anyone interested in the relation between the brain sciences and consciousness. (shrink)

In our contemporary post-modern context, it has become increasingly awkward to talk about a good that is shared by all. This is particularly true in the context of mammoth multi-national corporations operating in global markets. Nevertheless, it is precisely some of these same enormous, aggrandizing forces that have given rise to recent corporate scandals. These, in turn, raise questions about ethical systems that are focused too myopically on self-interest, or the interest of specific groups, locations or cultures. The obvious traditional (...) alternative to moral bellybutton gazing is the common good, which challenges the modern business enterprise to realize non-instrumental values that can only be attained in our life together. The common good dictates that leadership should be judged, first of all, according to moral criteria rather than professional competence. It helps correct the distorted prioritization of the maximization of profit in every business decision, recognizing that businesses have a multitude of rights and responsibilities, and the common good reminds us that the first of these is not always profit-making.

My aim in this paper is to articulate further what may be called an agency theory of self-knowledge. Many theorists have stressed how important agency is to self- knowledge, and much work has been done drawing connections between the two notions.² However, it has not always been clear what _epistemic_ advantage agency gives us in this area and why it does so. I take it as a constraint on an adequate account of how a subject knows her own mental states (...) and acts, that it construe the known mental states and acts realistically and as independent of their self-ascription, and that it deliver genuine epistemic standing to the knower. The main task of the paper will, then, be to explore how our having rational agency with respect to our mental states may be able to secure genuine epistemic warrant for our self-ascriptions of states or acts independent of the ascriptions. This task will be carried out by focussing on the question of what account we should give of our knowledge of what I call our acts of judging. In the remainder of this section, I will do a little to clarify what is meant by that question. Section 2 will attempt to introduce us to elements of the best way to approach the question by considering some alternative strategies. Section 3 is devoted to forming some idea of what _kind_ of warrant we are looking for when considering how agency might give us self-knowledge. Section 4 aims to present a suggestion as to how agency gives us the kind of warrant identified over our acts of judging. Section 5 deals with some objections. (shrink)

There have been a number of challenges to the Simple View—the view that an intention to A is necessary if an agent is to A intentionally. Michael Bratman’s celebrated video game case has convinced many that the view is false. This article presents a novel objection to Bratman’s case. It is argued, first, that the Simple View is not undermined by the case, and second, that the real import of the case is that it raises the question of how we (...) can rationally intend mutually exclusive ends. I offer a solution to this puzzle that draws on what I call the Self-Evaluation aspect of intention. (shrink)

Stich begins his paper "What is a Theory of Mental Representation?" by noting that while there is a dizzying range of theories of mental representation in today's philosophical market place, there is very little self-conscious reflection about what a theory of mental representation is supposed to do. This is quite remarkable, he thinks, because if we bother to engage in such reflection, some very surprising conclusions begin to emerge. The most surprising conclusion of all, according to Stich, is that most (...) of the philosophers in this field are undertaking work that is quite futile: " It is my contention that most of the players in this very crowded field have _no_ coherent project that could possibly be pursued successfully with the methods they are using. " Stich readily admits that this is a startling conclusion; so startling, he thinks, that some may even take it as an indication that he has simply "failed to figure out what those who are searching for a theory of mental representation are up to". But it is a conclusion that he is willing to stand by, and he sets about it defending it in the body of his paper. (shrink)

_"The Essential Plotinus_ is a lifesaver. For many years my students in Greek and Roman Religion have depended on it to understand the transition from antiquity to the Middle Ages. The translation is crisp and clear, and the excerpts are just right for an introduction to Plotionus's many-layered view of the world and humankind’s place in it." --F. E. Romer, University of Arizona.

This paper argues that Gareth Evans' treatment of first person reference based on the myriad ways we have of receiving information about our bodies and location, cannot secure the guaranteed reference exhibited by first person reference. It faces a problem both when a subject fails to receive such information about herself, and when she receives misinformation.

Reformers urge that representation no longer earns its explanatory keep in cognitive science, and that it is time to discard this troublesome concept. In contrast, we hold that without representation cognitive science is utterly bereft of tools for explaining natural intelligence. In order to defend the latter position, we focus on the explanatory role of representation in computation. We examine how the methods of digital and analog computation are used to model a relatively simple target system, and show that representation (...) plays an in-eliminable explanatory role in both cases. We conclude that, to the extent that biologic systems engage in computation, representation is destined to play an explanatory role in cognitive science. (shrink)

In certain situations, lies can be used to pass on knowledge. The kinds of cases I focus on are those involving a speaker's devious manipulation of the hearer's irrational or prejudiced thought. These cases show that sometimes a speaker's knowledge of a hearer's mind is necessary for the testimonial transmission of knowledge. They also support a 'seeding' model of knowledge transmission, rather than one that is akin to the postal delivery of complete parcels of information.

When it comes to applying computational theory to the problem of phenomenal consciousness, cognitive scientists appear to face a dilemma. The only strategy that seems to be available is one that explains consciousness in terms of special kinds of computational processes. But such theories, while they dominate the field, have counter-intuitive consequences; in particular, they force one to accept that phenomenal experience is composed of information processing effects. For cognitive scientists, therefore, it seems to come down to a choice between (...) a counter-intuitive theory or no theory at all. We offer a way out of this dilemma. We argue that the computational theory of mind doesn't force cognitive scientists to explain consciousness in terms of computational processes, as there is an alternative strategy available: one that focuses on the representational vehicles that encode information in the brain. This alternative approach to consciousness allows us to do justice to the standard intuitions about phenomenal experience, yet remain within the confines of cognitive science. (shrink)

Oaksford & Chater (O&C) have rejected logic in favor of probability theory for reasons that are irrelevant to mental-logic theory, because mental-logic theory differs from standard logic in significant ways. Similar to O&C, mental-logic theory rejects the use of the material conditional and deals with the completeness problem by limiting the scope of its procedures to local sets of propositions.

We think the best prospect for a naturalistic explanation of phenomenal consciousness is to be found at the confluence of two influential ideas about the mind. The first is the _computational _ _theory of mind_: the theory that treats human cognitive processes as disciplined operations over neurally realised representing vehicles.1 The second is the _representationalist theory of _ _consciousness_: the theory that takes the phenomenal character of conscious experiences (the “what-it-is-likeness”) to be constituted by their representational content.2 Together these two (...) theories suggest that phenomenal consciousness might be explicable in terms of the representational content of the neurally realised representing vehicles that are generated and manipulated in the course of cognition. The simplest and most elegant hypothesis that one might entertain in this regard is that conscious experiences are identical to (i.e., are one and the same as) the brain’s representing vehicles.

In assessing what the paradoxes meant to Plato, O'Brien uses certain broad principles of inquiry. First, he insists, any platonic doctrine must be placed in the context of Plato's whole philosophy--a truism not always honored. Second, the conversations of the dialogue form do not merely embellish Plato's philosophical statements but radically affect their expression. Originally published in 1967.

In this paper I want to propose that we see solipsism as arising from certain problems we have about identifying ourselves as subjects in an objective world. The discussion will centre on Wittgenstein.

In this paper we defend a position we call radical connectionism. Radical connectionism claims that cognition _never_ implicates an internal symbolic medium, not even when natural language plays a part in our thought processes. On the face of it, such a position renders the human capacity for abstract thought quite mysterious. However, we argue that connectionism is committed to an analog conception of neural computation, and that representation of the abstract is no more problematic for a system of analog vehicles (...) than for a symbol system. Natural language is therefore not required as a representational medium for abstract thought. Since natural language is arguably not a representational medium _at all_, but a conventionally governed scheme of communicative signals, we suggest that the role of internalised (i.e., self- directed) language is best conceived in terms of the coordination and control of cognitive activities within the brain.

ANALOGY has not just to do with the abstruse details and niceties of metaphysics but rather underlies the structure of all metaphysical thought. It is the heart of metaphysics. No system of metaphysics can discard it, without prejudice to the richness and variety of being. Without analogy there is elimination and over-simplification. Metaphysics is far from being a straightforward science; it is highly complex and its method and style of argument are not easy to master. Its field of inquiry is (...) wide. It is the task of the metaphysician to reduce the world of things to an intelligible unity. (shrink)

In Connectionism and the Philosophy of Psychology, Horgan and Tienson (1996) argue that cognitive processes, pace classicism, are not governed by exceptionless, “representation-level” rules; they are instead the work of defeasible cognitive tendencies subserved by the non-linear dynamics of the brain’s neural networks. Many theorists are sympathetic with the dynamical characterisation of connectionism and the general (re)conception of cognition that it affords. But in all the excitement surrounding the connectionist revolution in cognitive science, it has largely gone unnoticed that connectionism (...) adds to the traditional focus on computational processes, a new focus – one on the vehicles of mental representation, on the entities that carry content through the mind. Indeed, if Horgan and Tienson’s dynamical characterisation of connectionism is on the right track, then so intimate is the relationship between computational processes and representational vehicles, that connectionist cognitive science is committed to a resemblance theory of mental content.

In this chapter I defend a novel view of the relationships among intention for the future, self-control, and co-operation. I argue that when an agent forms an intention for the future she comes to regard herself as criticizable if she does not act in accordance with her intention and as praiseworthy if she does. In forming intentions, then, agents acquire dispositions to have reflexive evaluative attitudes. In contexts where the agent has inclinations that run contrary to her unrescinded intention, these (...) evaluative attitudes help her to resist these inclinations. Intentions have, in other words, a built-in mechanism for self-control. I go on to argue that this mechanism can also function as a mechanism for co-operative behaviour. Sometimes a common species of co-operation just is the exercise of self-controlled behaviour in a social context. If this is on the right track, agents like us are not just equipped to formulate and abide by plans for the future, we are also thereby equipped for exercising self-control and participating in co-operative ventures.

The connectionist vehicle theory of phenomenal experience in the target article identifies consciousness with the brain’s explicit representation of information in the form of stable patterns of neural activity. Commentators raise concerns about both the conceptual and empirical adequacy of this proposal. On the former front they worry about our reliance on vehicles, on representation, on stable patterns of activity, and on our identity claim. On the latter front their concerns range from the general plausibility of a vehicle theory to (...) our specific attempts to deal with the dissociation studies. We address these concerns, and then finish by considering whether the vehicle theory we have defended has a coherent story to tell about the active, unified subject to whom conscious experiences belong.

The project of the paper is a critical examination of the "strong thesis of eliminative materialism" in the philosophy of mind--The claim that all the mental entities that constitute the framework of commonsense psychology are, In principle at least, Eliminable from our ontology. The central conclusion reached is that the traditional formulation of this thesis is demonstrably untenable as it rests on a mistaken view of the relationship between our psychological self-Knowledge and language.
