Post-Gibson attempts to set out a definition of affordance generally agree that this notion can be understood as a property of the environment with salience for an organism’s behavior. According to this view, some scholars advocate the idea that affordances are dispositional properties of physical objects that, given suitable circumstances, necessarily actualize related actions. This paper aims at assessing this statement in light of a theory of affordance perception. After years of discontinuity between strands of empirical and theoretical (...) research, the time is ripe for addressing the question of whether the dispositional interpretation of affordance is in accordance with some recent evidence from cognitive science and neuroscience. Following this line, I clarify that there are some cases of affordance-related effects that neither require the actualization of an action, nor the presence of an action-related property bearer in the environment, and that the identification of affordance with physical properties provides only a partial explanation of the wide range of affordance-related effects. Accordingly, I argue in favor of a more general account of affordance perception based on the ability to directly detect perceptual patterns in the environment. (shrink)

This article is interdisciplinary in its claims. Evolving around the ecological concept of affordance, it brings together pragmatics and ecological psychology. Starting from the theoretical writings of Peirce, Dewey and James, the biosemiotic claims of von Uexküll, Gibson’s ecological approach to perception and some empirical evidence from recent neurobiological research, it elaborates on the concepts of experiential and enactive cognition as applied to music. In order to provide an operational description of this approach, it introduces some conceptual tools from (...) the domain of cybernetics with a major focus on the concept of circularity, which links perception to action in a continuous process of sense-making and interaction with the environment. As such, it is closely related to some pragmatic, biosemiotic and ecosemiotic claims which can be subsumed under the general notion of functional significance. An attempt is made to apply this conceptual framework to the process of musical sense-making which involves the realisation of systemic cognition in the context of epistemic interactions that are grounded in our biology and possibilities for adaptive control. Central in this approach is the concept of coping with the environment, or, in musical terms, to perceive the sounding music in terms of what it affords for the consummation of musical behaviour.

I provide an analysis of the concept of an “affordance” that enables one to conceive of “structural affordance” as a kind of affordance relation that might hold between an agent and its body. I then review research in the science of humanoid bodily movement to indicate the empirical reality of structural affordance.

An embodied movement-planning field cannot account for behavior and cognition more abstract than that of reaching. Instead, we propose an affordance field, and we sketch how it could enhance the analysis of the A-not-B error, underlie cognition, and serve as a base for language. Admittedly, a dynamic systems account of an affordance field awaits significant further development.

Millikan's discussion of substance concepts in terms of their information-gathering role ignores the analyses of information-based perception and action developed within the tradition of ecological psychology. Her introduction and use without definition of key Gibsonian terms such as “affordance” and “direct perception” leaves those of us investigating such concepts uncertain of the extent to which she appreciates their theoretical importance. Due recognition of the realist account of categorical perception developed by J. J. Gibson would provide mutual benefit to modern (...) externalist philosophy as well as to experimental psychology and to those investigating the ecological approach to perception–action. (shrink)

Opposed to Norman's proposal, processing of affordance is likely to occur not solely in the dorsal stream but also in the ventral stream. Moreover, the dorsal stream might do more than just serve an important role in motor actions. It supports egocentric location coding as well. As such, it would possess a form of representational memory, contrary to Norman's proposal.

This paper revisits the concept of affordance and explores its contribution to an understanding of the use of ICT for teaching and learning. It looks at Gibson‟s original idea of affordance and at some of the difficulties long associated with the use of the word. It goes on to describe the translation of the concept of affordance into the field of design through the work, in particular, of Norman. The concept has since been translated into research concerning (...) ICT and further opportunities and difficulties emerge. The paper locates key points of divergence within the usage of „affordance‟, as involving direct perception, invariant properties and complementarity. It concludes by arguing that affordance offers a distinctive perspective on the use of ICT in education because of its focus on possibilities for action. (shrink)

Metacognition is associated with planning, monitoring, evaluating and repairing performance Designers of elearning systems can improve the quality of their environments by explicitly structuring the visual and interactive display of learning contexts to facilitate metacognition. Typically page layout, navigational appearance, visual and interactivity design are not viewed as major factors in metacognition. This is because metacognition tends to be interpreted as a process in the head, rather than an interactive one. It is argued here, that cognition and metacognition are part (...) of a continuum and that both are highly interactive. The tenets of this view are explained by reviewing some of the core assumptions of the situated and distribute approach to cognition and then further elaborated by exploring the notions of active vision, visual complexity, affordance landscape and cue structure. The way visual cues are structured and the way interaction is designed can make an important difference in the ease and effectiveness of cognition and metacognition. Documents that make effective use of markers such as headings, callouts, italics can improve students' ability to comprehend documents and 'plan' the way they review and process content. Interaction can be designed to improve 'the proximal zone of planning' - the look ahead and apprehension of what is nearby in activity space that facilitates decisions. This final concept is elaborated in a discussion of how e-newspapers combine effective visual and interactive design to enhance user control over their reading experience. (shrink)

The complexities of bodily experience are outlined; its spatial phenomenology is specified as the explanatory target. The mereological structure of body representation is discussed; it is claimed that global spatial representations of the body are not necessary, as structural features of the actual body can be exploited in partial internal representation. The spatial structure of bodily experience is discussed; a structural affordance theory is introduced; it is claimed that bodily experience and subpersonal representation have action-orientated content; and that egocentric (...) terms continue to make sense in application to bodily experience.

These comments claim that a shift has occurred between early discussions of online trust, where the focus was on the possibility of such trust and later ones, such as Ess’s, where the concern is more with the influence of the new communication technologies on trust in general. The comments, then, focus on affordance as examined by Ess, arguing that it is, indeed, a central issue in new communications and trust.

We propose to understand social affordances in the broader context of responsiveness to a field of relevant affordances in general. This perspective clarifies our everyday ability to unreflectively switch between social and other affordances. Moreover, based on our experience with Deep Brain Stimulation for treating OCD patients, we suggest that psychiatric disorders may affect affordance-responsiveness, including responsiveness to social affordances.

I argue that the most promising approach to understanding J.J. Gibson's "affordances" takes affordances themselves as ontological primitives, instead of treating them as dispositional properties of more primitive things, events, surfaces, or substances. These latter are best treated as coalescences of affordances present in the environment (or "coalescences of use-potential," as in Sanders (1994) and Hilditch (1995)). On this view, even the ecological approach's stress on the complementary organism/environment pair is seen as expressing a particular affordance relation between the (...) world and the analyst. That the world is parsed in any way among events and objects, perceivers and worlds, etc., reflects equally features of certain real or possible perspectives on the world and features of the world itself. In section 1, I begin by contending that, contrary to the apparent expectations of some in the field, the bare existence of affordances is surely quite uncontroversial. In section 2, I argue that the most reasonable approach to foundational ontology is a relativistic one. In section 3, I address the claim that affordances must be ontologically complemented by effectivities for the sake of completeness, and I shall argue against that claim on grounds that I take to reflect some of Gibson's most important insights. This work will help to clarify the way affordances are to be used in the fourth and final section, where I argue that ontological work, even within special sciences, should not be merely "regional," and that the most attractive general approach to ontological questions is one that is based on affordances, rather than upon things, events, surfaces, and the like.

James Gibson’s concept of affordances was an attempt to undermine the traditional dualism of the objective and subjective. Gibson himself insisted on the continuity of “affordances in general” and those attached to human artifacts. However, a crucial distinction needs to be drawn between “affordances in general” and the “canonical affordances” that are connected primarily to artifacts. Canonical affordances are conventional and normative. It is only in such cases that it makes sense to talk of the affordance of the object. (...) Chairs, for example, are for sitting-on, even though we may also use them in many other ways. A good deal of confusion has arisen in the discussion of affordances from (1) the failure to recognize the normative status of canonical affordances and (2) then generalizing from this special case.

There are important structural similarities in the way that animals and humans engage in unreflective activities, including unreflective social interactions in the case of higher animals. Firstly, it is a form of unreflective embodied intelligence that is ‘motivated’ by the situation. Secondly, both humans and non-human animals are responsive to ‘affordances’ (Gibson 1979); to possibilities for action offered by an environment. Thirdly, both humans and animals are selectively responsive to one affordance rather than another. Social affordances are a subcategory (...) of affordances, namely possibilities for social interaction offered by an environment: a friend’s sad face invites comforting behavior, a person waiting for a coffee machine can afford a conversation, and an extended hand affords a handshake. I will review recent insights in the nature of the bodily intentionality characteristic of unreflective action. Such ‘motor intentionality’ can be characterized as “our direct bodily inclination to act in a situated, environmental context” (Kelly 2005, p. 106). Standard interpretations of bodily intentionality see grasping an object as the paradigmatic example of motor intentionality. I will discuss the implications of another, novel perspective that emphasizes the importance of unreflective switches from one activity to another (Rietveld 2004) and understands bodily intentionality in terms of adequate responsiveness to a field of relevant affordances. In the final section I will discuss some implications for cognitive neuroscientists who use empirical findings related to the ‘mirror neuron system’ as a starting point for a theory of motor intentionality and social cognition.

In his ecological approach to perception, james gibson introduced the concept of affordance to refer to the perceived meaning of environmental objects and events. this paper examines the relational and causal character of affordances, as well as the grounds for extending affordances beyond environmental features with transcultural meaning to include those features with culturally-specific meaning. such an extension is seen as warranted once affordances are grounded in an intentional analysis of perception. toward this end, aspects of merleau-ponty's treatment of (...) perception are explored. finally, a resolution of the apparent tension between the relational and perceiver-independent nature of affordances is presented.

I examine the central theoretical construct of ecological psychology, the concept of an affordance. In the first part of the paper, I illustrate the role affordances play in Gibson's theory of perception. In the second part, I argue that affordances are to be understood as dispositional properties, and explain what I take to be their characteristic background circumstances, triggering circumstances and manifestations. The main purpose of my analysis is to give affordances a theoretical identity enriched by Gibson's visionary insight, (...) but independent of the most controversial claims of the Gibsonian movement.

According to John McDowell, representational perceptual content is conceptual through and through. This paper criticizes this view by claiming that there is a certain kind of representational and non-conceptual perceptual content that is sensitive to bodily skills. After a brief introduction to McDowell's position, Merleau-Ponty's notion of body schema and Gibson's notion of affordance are presented. It is argued that affordances are constitutive of representational perceptual content, and that at least some affordances, (...) the so-called 'conditional affordances', are essentially related to the body schema. This means that the perceptual content depends upon the nature of the body schema. Since the body schema does not pertain to the domain that our conceptual faculties operate upon, it is argued that this kind of perceptual content cannot be conceptual. At least some of that content is representational, yet it cannot feature as non-demonstrative conceptual content. It is argued that if it features as demonstrative conceptual content, it has to be captured by private concepts. Since McDowell's theory does not allow for the existence of a private language, it is concluded that at least some representational perceptual content is non-conceptual. (shrink)

Intentionalism is the view that the phenomenal character of a conscious experience is wholly determined by, or even reducible to, its representational content. In this essay I put forward a version of intentionalism that allows (though does not require) the reduction of phenomenal character to representational content. Unlike other reductionist theories, however, it does not require the acceptance of phenomenal externalism (the view that phenomenal character does not supervene on the internal state of the subject). According the view offered here, (...) phenomenal characters essentially represent subject-environment relations that are relevant to the possibilities for causal interaction between the subject and the environment; relations of the kind that J. J. Gibson dubbed affordances. I argue for this view chiefly through an examination of spatial perception, though other cases are also considered. The view assumes that a phenomenal character has an essential functional role; though it need not be assumed that a functional role is sufficient for a phenomenal character. (shrink)

Using hypersets as an analytic tool, we compare traditionally Gibsonian (Chemero 2003; Turvey 1992) and representationalist (Sahin et al. this issue) understandings of the notion ‘affordance’. We show that representationalist understandings are incompatible with direct perception and erect barriers between animal and environment. They are, therefore, scarcely recognizable as understandings of ‘affordance’. In contrast, Gibsonian understandings are shown to treat animal-environment systems as unified complex systems and to be compatible with direct perception. We discuss the fruitful connections between (...) Gibsonian affordances and dynamical systems explanation in the behavioral sciences and point to prior fruitful application of Gibsonian affordances in robotics. We conclude that it is unnecessary to re-imagine affordances as representations in order to make them useful for researchers in robotics. (shrink)

In this paper I aim to present an explanation of object permanence that is derived from an ecological account of perceptually based action. In understanding why children below a certain age do not search for occluded objects, one must first understand the process by which these children perform certain intentional actions on non-occluded items; and to do this one must understand the role affordances play in eliciting retrieval behaviour. My affordance-based explanation is contrasted with Shinskey and Munakata's graded representation (...) account; and although I do not reject totally the role representations play in initiating intentional action I nevertheless maintain that only by incorporating direct perception into an account of object permanence can a fuller understanding of this phenomenon be achieved.

This article is about a sidebar in James Gibson's last book, The ecological approach to visual perception. In this sidebar, Gibson, the founder of the ecological perspective of perception and action, argued that to perceive an affordance is not to classify an object. Although this sidebar has received scant attention, it is of great significance both historically and for recent discussions about specificity, direct perception, and the functions of the dorsal and ventral streams. It is argued that Gibson's acknowledgment (...) of Wittgenstein's ideas of classification suggests a limited scope of his theory of direct perception?it cannot account for the classification of objects. The implications for both the specification debate and theorizing about the brain's dorsal and ventral pathways are explored. Based on a recent ecological conception of information and direct perception, we ultimately argue that both affordance perception and classification are direct. (shrink)

Interest in "embodiment", and over how one may best express the implications of embodiment, is no parochial question, of interest only to a small number of effete philosophers. It confronts perceptual psychologists, developmental psychologists, and psychotherapists, of course. It may not be surprising, either, that it has become an important issue to some students of history and sociology, and to linguists, literary theorists and aestheticians. But that's not all. As physicists -- working within the very bastion of "objective" analysis -- (...) have tried to find expression for what seems to be going on in the domain of sub-atomic nature, they have begun to suggest that physical description itself is inevitably situated. And within the study of artificial intelligence, support is growing for the contention that intelligence cannot be understood entirely formalistically. Intelligence must at least be embodied -- it must somehow display "engaged agency" -- if it is to be recognizable as intelligence. It is within this context that the contribution offered by this essay must be understood. I shall contend that a particular conception -- that of "affordances" -- can, when suitably qualified, offer a conceptual tool of quite exceptional value in the construction of a positive theory of embodied agency, and of its philosophical consequences.

Upshot: Chemero provides a modern re-interpretation of Gibson’s ecological psychology and his affordance concept that is more coherent than the original and in line with antirepresentationalist, dynamical theories in embodied cognitive science. He argues for a radical embodied cognitive science, in which ecological and enactive approaches join forces against the more watered-down, mainstream embodied cognitive science that still maintains traditional commitments to representationalism and computationalism. He also defends a special version of realism, entity realism, which many constructivists might not (...) find entirely convincing, but which is nevertheless more or less compatible with enactive theories of embodied cognition.

The recent confirmation of the constitutionality of the Obama administration’s Patient Protection and Affordable Care Act (PPACA) by the US Supreme Court has brought to the fore long-standing debates over individual liberty and religious freedom. Advocates of personal liberty are often critical, particularly in the USA, of public health measures which they deem to be overly restrictive of personal choice. In addition to the alleged restrictions of individual freedom of choice when it comes to the question of whether or not (...) to purchase health insurance, opponents to the PPACA also argue that certain requirements of the Act violate the right to freedom of conscience by mandating support for services deemed immoral by religious groups. These issues continue the long running debate surrounding the demands of religious groups for special consideration in the realm of health care provision. In this paper I examine the requirements of the PPACA, and the impacts that religious, and other ideological, exemptions can have on public health, and argue that the exemptions provided for by the PPACA do not in fact impose unreasonable restrictions on religious freedom, but rather concede too much and in so doing endanger public health and some important individual liberties.

This paper illustrates how affordance-based design can contribute to solutions for the grand challenges that society faces. The design methodology of ‘strategic interventions’ is explained.

This paper widens the scope of our previous paper (Harré and Llored in Found Chem 13:63–76, 2011) by scrutinizing how whole/parts relations are involved in the study of molecules. In doing so, we point out two mereological fallacies which endanger both philosophical and chemical inferences. We also further explore how the concept of affordance is related to our mereological investigation. We then refer to quantum chemistry in order to pave the way for a new mereological approach for chemistry.

In her essay --?Information, Perception and Action--, Claire Michaels reaches two conclusions that run very much against the grain of ecological psychology. First, she claims that affordances are not perceived, but simply acted upon; second, because of this, perception and action ought to be conceived separately. These conclusions are based upon a misinterpretation of empirical evidence which is, in turn, based upon a conflation of two proper objects of perception: objectively with properties and affordances.

In this essay we respond to some criticisms of the guidance theory of representation offered by Tom Roberts. We argue that although Roberts’ criticisms miss their mark, he raises the important issue of the relationship between affordances and the action-oriented representations proposed by the guidance theory. Affordances play a prominent role in the anti-representationalist accounts offered by theorists of embodied cognition and ecological psychology, and the guidance theory is motivated in part by a desire to respond to the critiques of (...) representationalism offered in such accounts, without giving up entirely on the idea that representations are an important part of the cognitive economy of many animals. Thus, explorations of whether and how such accounts can in fact be related and reconciled potentially offer to shed some light on this ongoing controversy. Although the current essay hardly settles the larger debate, it does suggest that there may be more possibility for agreement than is often supposed. (shrink)

Recent economic and political advances in developing countries on the African continent and South East Asia are threatened by the rising death and morbidity rates of HIV/AIDS. In the first part of this paper we explain the reasons for the absence of affordable access to essential AIDS medication. In the second part we take a closer look at some of the pivotal frameworks relevant for this situation and undertake an ethical analysis of these frameworks. In the third part we discuss (...) a few of the proposed solutions to the problem and conclude with an argument in support of our preferred course of action. In this article we argue for compulsory licensing of essential AIDS medications in the current conditions of public health emergency. We argue on broadly consequentialist grounds that compulsory licensing is preferable both morally and pragmatically to the alternatives, notably the currently offered price cuts and drug donation schemes.

The Patient Protection and Affordable Care Act (ACA) sets in motion a wide range of programs that substantially affected the health system in the United States and signify a moderate but important regulatory shift in the role of the federal government in public health. This article briefly addresses two interesting policy paradoxes about the ACA. First, while the legislation primarily addresses health care financing and insurance and establishes only a few initiatives directly targeting public health, the ACA nevertheless has the (...) potential to produce extensive public health benefits across the United States population by improving access to health care and services and reducing cost. Essentially, the ACA does not take the explicit form of a public health law but instead strives to advance public health indirectly through its effects. Second, while the ACA does not establish a right to health — or even a right to health insurance — in the United States, it does set in motion a number of significant structural and normative changes to United States law that comport with the attainment of the right to health. Most significantly, key provisions of the bill are designed to improve availability, accessibility, acceptability, and quality of conditions necessary for health, and to prompt the government to respect, protect, and fulfill these conditions. These developments mean that, to a degree, the United States essentially has undertaken the same types of legal and policy steps that a country would be required to take to uphold the right to health without actually recognizing the right to health in any formal or legally binding way.Despite these dual paradoxes and the upside potential for public health improvements resulting from the ACA, the public health impact of the law remains uncertain and will be decided by numerous subsequent regulatory and implementation decisions. The ACA authorizes multiple federal agencies to engage in rulemaking, a process that will largely dictate the systemic and health impacts that will become its legacy. This reality opens up ample opportunity to bolster public health aspects and interpretations of the law, and to simultaneously augment the corresponding components of the right to health. (shrink)

In a target article that appeared in this journal, Thomas Stoffregen 2000 questions the possibility of ecological event perception research. This paper describes an experiments performed to examine the perception of the disappearance of gap-crossing affordances, a variety of event as defined by Chemero 2000. We found that subjects reliably perceive both gap-crossing affordances and the disappearance of gap-crossing affordances. Our findings provide empirical evidence in favor of understanding events as changes in the layout of affordances, shoring up event perception (...) research in ecological psychology. (shrink)

The Affordable Care Act (ACA) transforms the U.S.'s public and private health care financing systems into vehicles for promoting public health by making evidence-based preventive services available nationwide through individual and group health plans, Medicare, and Medicaid. The ACA accomplishes this transformation by breaking down two barriers: (1) the public health-health care divide, which led to a dominance of curative medicine over preventive health measures and (2) ERISA preemption, which created an obstacle to the provision of a uniform set of (...) evidence-based preventive services that could be made available to the U.S. population through individual and group health plans. As a result, prevention measures with proven effectiveness will now be provided on a national and uniform basis to a majority of Americans, with the potential to improve health outcomes and reduce costs.

In a recent important book,The Ethics of International Business, Tom Donaldson argues that multinational corporations (as well as individuals and nationstates) must, at a minimum, respect international human rights. For a purported right to be such a fundamental right it must satisfy three conditions. Donaldson calls the third condition the fairness-affordability condition. The affordability part of this condition holds that moral agents must be capable of paying for the burdens and responsibilities that a proposed human right would impose. If this (...) is impossible, then the purported right is not an international human right.I argue that Donaldson''s affordability condition is subject to four objections which reveal its untenability as one of the conditions upon which identification of international human rights must rest. I offer another way of treating problems of affordability and capability when it comes to such rights that all moral agents must respect. (shrink)

This article presents a new proposal for understanding the establishment and maintenance of cooperation: the cooperation afforder with framing hypothesis, producing what can be called cooperation from afforder-framing . Three key moves are present. First, a special variety of the Stag Hunt game, the Cooperation Afforder game, will reliably produce mutualistic cooperation through an evolutionary process. Second, cognitive framing is a credible candidate mechanism to meet the special conditions and requirements of the Cooperation Afforder game. Third, once mutualistic cooperation is (...) established in this way, it will plausibly lead to broader forms of cooperation, even to limited forms of altruism. (shrink)

This study investigates the relationship between workers'' perceptions of distributive and procedural justice afforded by a grievance system and their more general belief in an underlying moral order in the workplace. Using samples representing five ocupationally distinct groups, the presence of any moderating effects of occupation received only weak support. Consistent with previous work, however, workers'' perceptions of procedural justice (i.e., fairness in the process) were a stronger predictor of workers'' belief in workplace justice than were perceptions of distributive justice (...)

Despite evidence indicating that public health services are the most effective means of improving the population's health status, health care services receive the bulk of funding and political support. The recent passage of the Affordable Care Act, which focused on improving access to health care services through insurance reform, reflects the primacy of health care over public health. Although policymakers typically conceptualize health care and public health as two distinct systems, gains in health status are most effectively and cost-efficiently achieved (...) through their integration into a single health system. The Act does little to compel integration; however, there are numerous opportunities to encourage the coordination of public health and health care in the Act's implementation. (shrink)

How is meaning assigned to those terms in a theory which are remote from direct observational instantiation? Models and analogies play a role, but close examination of theories in high energy physics shows that the design of experimental apparatus also influences the interpretation of such terms. Certain apparatus favours certain kinds of effects, and this affects the way mathematical theories are interpreted. In particular track producing apparatus becomes involved with theories in which photonic terms are picked out in the theory. (...) A further conceptual constraint is thus introduced. It is argued that this situation favours the interpretation of dispositional properties as affordances rather than as simple dispositions. (shrink)

The cost of health care imposes an extremely difficult, and often impossible, burden for many people to bear. It is also a burden that men and women do not experience in the same way. Evidence shows that “women have greater difficulty affording health care” (Patchias and Waxman 2007, 6). In the United States, 62 percent of working-age women in 2007—compared to 48 percent of working-age men—reported problems in affording health care, including not being able to pay medical bills, foregoing or (...) delaying needed care because of cost, or both (Rustgi, Doty, and Collins 2009).

The idea that natural language grammar and planned action are relatedsystems has been implicit in psychological theory for more than acentury. However, formal theories in the two domains have tendedto look very different.

Viewing them in thisway suggests simpler and more cognitively plausible accounts of bothsystems, and suggests that the language faculty evolved in the (...) speciesand develops in children by a rather direct adaptation of a moreprimitive apparatus for planning purposive action in the world bycomposing affordances of objects or tools.

Dr Anne Merriman is the founder of Hospice Africa and Hospice Africa Uganda. She is presently Director of Policy and International Programmes. Here she tells the story of how HAU was founded. Dr Richard Harding is an academic researcher working on palliative care in Sub-Saharan Africa. This paper described Dr Merriman's experience in pioneering palliative care provision. In particular it examines the steps to achieving wider availability of opioids for pain management for those with far advanced disease. Hospice Africa Uganda (...) has been a model facility in achieving high quality clinical care embedded in a strategy of advocacy and education, using a multifaceted approach that has addressed logistical, policy and legislative barriers. Until 1990 control of severe pain in Sub-Saharan Africa was non-existent except in Zimbabwe and S Africa. Oral affordable morphine was brought to Kenya through Nairobi Hospice that year, and to Uganda through Hospice Africa Uganda in 1993. This paper offers an example of a highly effective and cost efficient model of care that has transformed the ability to humanely manage the problems of those with terminal illness, and to offer a culturally appropriate "good death". Thus it is now possible to complete the ethical circle of care in resource poor circumstances. (shrink)

Within philosophy there is not yet an integrative account of unreflective skillful action. As a starting point, contributions would be required from philosophers from both the analytic and continental traditions. Starting from the McDowell-Dreyfus debate, shared Aristotelian-Wittgensteinian common ground is identified. McDowell and Dreyfus agree about the importance of embodied skills, situation-specific discernment and responsiveness to relevant affordances. This sheds light on the embodied and situated nature of adequate unreflective action and provides a starting point for the development of an (...) account that does justice to insights from both philosophical traditions.

Our everyday activities unfold in situations that offer a multiplicity of possibilities for action. While typing this text, the apple on the right side of my laptop affords eating, my e-mail checking, and the glass of water drinking from it. Every now and then I unreflectively switch from typing to eating or drinking and back to typing again. A relevant possibility for action is embedded in a field of other soliciting possibilities for action (Rietveld, 2008). Michael Wheeler and Hubert Dreyfus (...) have an interesting debate on the important issue of cognition in context. They both take a naturalistic and broadly Heideggerian approach to the problem of adequate sensitivity to context-dependent relevance (the frame-problem). Their debate focuses on such sensitivity in episodes of online intelligence (Wheeler, 2005, p. 252, p. 280), typing for instance. They agree that a central phenomenon to be understood is how one switches from one context to another by being responsive to what is relevant in a given situation. I use this latter agreement as a starting point for a new perspective on online intelligence. (shrink)

The primary difference between direct and inferential theories of perception concerns the location of perceptual content, the meaning of our perceptions. In inferential theories of perception, these meanings arise inside animals, based upon their interactions with the physical environment. Light, for example, bumps into receptors causing a sensation. The animal (or its brain) performs inferences on the sensation, yielding a meaningful perception. In direct theories of perception, on the other hand, meaning is in the environment, and perception does not depend (...) upon meaning- conferring inferences. Instead the animal simply gathers information from a meaning- laden environment. But if the environment contains meanings, then it cannot be merely physical. This places a heavy theoretical burden on direct theories of perception, a burden so severe that it may outweigh all the advantages to conceiving perception as. (shrink)

For Merleau-Ponty,consciousness in skillful coping is a matter of prereflective ‘I can’ and not explicit ‘I think that.’ The body unifies many domain-specific capacities. There exists a direct link between the perceived possibilities for action in the situation (‘affordances’) and the organism’s capacities. From Merleau-Ponty’s descriptions it is clear that in a flow of skillful actions, the leading ‘I can’ may change from moment to moment without explicit deliberation. How these transitions occur, however, is less clear. Given that Merleau-Ponty suggested (...) that a better understanding of the self-organization of brain and behavior is important, I will re-read his descriptions of skillful coping in the light of recent ideas on neurodynamics. Affective processes play a crucial role in evaluating the motivational significance of objects and contribute to the individual’s prereflective responsiveness to relevant affordances. (shrink)

We present work demonstrating that the nature of an object for our visual system depends on the actions we are programming and on the presence of action relations between stimuli. For example, patients who show visual extinction are more likely to become aware of two objects if the objects fall in appropriate visual locations for a common action. This effect of the action relations between objects is modulated both by the familiarity of the positioning of the objects for action, and (...) by the mere possibility of action (the ‘affordance’) between the objects. In addition, the programming of an action to a part of an object alters the representation of that object, making the ‘part’ into the object selected by the visual system. These results point to object coding being a rather flexible process, affected not only by the perceptual properties of stimuli but also by the relations between these properties and action. We discuss the implications for theories of perception as well as considering why action information, in particular, may be important for perception. (shrink)

The idea that knowledge can be extended by inference from what is known seems highly plausible. Yet, as shown by familiar preface paradox and lottery-type cases, the possibility of aggregating uncertainty casts doubt on its tenability. We show that these considerations go much further than previously recognized and significantly restrict the kinds of closure ordinary theories of knowledge can endorse. Meeting the challenge of uncertainty aggregation requires either the restriction of knowledge-extending inferences to single premises, or eliminating epistemic uncertainty in (...) known premises. The first strategy, while effective, retains little of the original idea—conclusions even of modus ponens inferences from known premises are not always known. We then look at the second strategy, inspecting the most elaborate and promising attempt to secure the epistemic role of basic inferences, namely Timothy Williamson’s safety theory of knowledge. We argue that while it indeed has the merit of allowing basic inferences such as modus ponens to extend knowledge, Williamson’s theory faces formidable difficulties. These difficulties, moreover, arise from the very feature responsible for its virtue- the infallibilism of knowledge. (shrink)

Cynthia Freeland’s investigation of four kinds of ‘fidelity’ in portraiture is cut across by more general philosophical concerns. One is about what might be called the expression of persons--the persons or ‘inner selves’ of portrait subjects and of portrait artist: whether either is possible across each of the four kinds of fidelity, and whether these two kinds of expression are in tension. More fundamental is the problem of telling how self-expression is at all possible in any of these forms. Finally, (...) she wonders how photography affects all these questions. This comment addresses portraiture not so much in terms of the four fidelities, but with another quartet of concepts: four ordinary types of ‘display’, in terms of which we see how artists’ self-expression is possible in all these forms, also including photography. Its key idea is that portraits are displays simply by being pictures or sculptures, which are kinds of artifacts, hence things that we perceive as having intentional affordance: that is, as being intentionally made ‘for’ something.

Nagel has argued that the ‘mind-body’ problem, as traditionally conceived, is insoluble. His challenge to philosophers is to devise a metaphysical scheme that incorporates materialist concepts in describing first person experience and mentalistic concepts in describing third person experience, such that the internal relations between the concepts thereby constructed are necessary. Nagel's own suggestion, a scheme not unlike the ‘underlying process’ schemes of the physical sciences, seems to lead him towards a covert materialism. Progress can be made in meeting the (...) challenge by tackling the problem first by taking the units in each ‘sphere’ to be brains and persons. I show that a metaphysics based on the metaphor of person defined tasks and materially defined tools does satisfy both Nagel's challenge conditions. To devise a scheme for qualia and brain-states I turn back to Locke's presentation of the primary/secondary quality distinction. This depends on the concept of a causal power, grounded in material states of the world. While this scheme is inadequate, a variation, based on Gibson's concept of an affordance, and drawing on Bohr's resolution of the seeming incompatibility between wave and particle ontologies for physics, is promising. The world, whatever it is, affords material states to our perceptual apparatus, and mental states to our proprioceptual apparatus. The mental states/brain states duality is not a duality of types of states, which might stand in causal relations to one another, but is a duality of means of access to two classes of affordances of whatever the world is. There is no mind-body problem in the traditional sense, namely ‘How could a material state cause or be caused by a mental state?’. (shrink)

This paper is an exploration of how we do things with music—that is, the way that we use music as an esthetic technology to enact micro-practices of emotion regulation, communicative expression, identity construction, and interpersonal coordination that drive core aspects of our emotional and social existence. The main thesis is: from birth, music is directly perceived as an affordance-laden structure. Music, I argue, affords a sonic world, an exploratory space or nested acoustic environment that further affords possibilities for, among (...) other things, (1) emotion regulation and (2) social coordination. When we do things with music, we are engaged in the work of creating and cultivating the self, as well as creating and cultivating a shared world that we inhabit with others. I develop this thesis by first introducing the notion of a musical affordance . Next, I look at how emotional affordances in music are exploited to construct and regulate emotions. I summon empirical research on neonate music therapy to argue that this is something we emerge from the womb knowing how to do. I then look at social affordances in music, arguing that joint attention to social affordances in music alters how music is both perceived and appropriated by joint attenders within social listening contexts. In support, I describe the experience of listening to and engaging with music in a live concert setting. Thinking of music as an affordance-laden structure thus reaffirms the crucial role that music plays in constructing and regulating emotional and social experiences in everyday life. (shrink)

While there are numerous differences between the approaches taken by Maurice Merleau-Ponty and James J. Gibson, the basic motivation of the two thinkers, as well as the internal logic of their respective views, is extraordinarily close. Both were guided throughout their lives by an attempt to overcome the dualism of subject and object, and both devoted considerable attention to their "Gestaltist" predecessors. There can be no doubt but that it is largely because of this common cause that the subsequent development (...) of their ideas is so similar. It is not my objective in what follows merely to demonstrate a similarity between two lines of thought. Instead, I will try to show that each approach gains considerably from attention to the other. There are numerous ways to begin such a project, each about as arbitrary as the next. For present purposes, I shall take as of central importance the question of the character of the perceived world, both in relation to the traditionally opposed mental and material "substances", and in relation to its identification and individuation of things vis a vis one another and vis a vis ourselves. This will implicate especially Gibson's "affordances" and Merleau-Ponty's thesis concerning the "materiality of meaning.". (shrink)

Against David Schenck's interpretation, I argue that it is not absolutely clear that Merleau-Ponty ever meant to replace what Schenck refers to as the "unity of meanings" interpretation of "structure" with a "material meanings" interpretation. A particular problem-setting -- for example, an attempt to understand the "truth in naturalism" or the "truth in dualism" -- may very well require a particular mode of expression. I argue that the mode of expression chosen by Merleau-Ponty for these purposes, while unfortunate in some (...) of its apparent implications, need not be interpreted as recommitting him to the doctrine he spent his life working to renounce. I have argued that this would have been clearer had he been able to avail himself of James J. Gibson's notion of affordances, which capture perfectly what he was reaching for. (shrink)

An argument whose conclusion C is essential evidence for one of its premises can provide its target audience with justification for believing C. This is possible because we can enhance our justification for believing a proposition C by integrating it into an explanatory network of beliefs for which C itself provides essential evidence. I argue for this in light of relevant features of doxastic circularity, epistemic circularity, and explanatory inferences. Finally, I confirm my argument with an example and respond to (...) objections. (shrink)

In this paper, I develop the notion of the experiential workspace, or the phenomenal setting generated by the coupling between the enactive body and its affordance-laden environment, in order to carry out a fine-grained analysis of enactive experiential phenomena, in particular those of ordinary lived experience. My purpose is to shed light on some of the ways that empirical methodologies are intrinsically limited in their ability to capture the native phenomena of enactive, embodied (...) experience. Drawing on the work of Merleau-Ponty, I argue that the experiential workspace is characterized by dynamic mutability, emergent norms, and epistemic openness - characteristics that are transphenomenal in nature and thus resistant to empirical measurement. Using concepts from the work of developmental psychologist Lev Vygotsky (1978) and feminist philosopher Iris Marion Young (1998), I will show how our embeddedness in an intersubjective world makes the experiential workspace a mercurial, labile phenomenon, characterized by inherently transphenomenal features that are resistant to naturalistic analysis or modelling.

Exploiting the skills of others enables individuals to reduce the risks and costs of resource innovation. Social corvids are known to possess sophisticated social and physical cognitive abilities. However, their capacity for imitative learning and its inter-individual transmission pattern remains mostly unexamined. Here we demonstrate the large-billed crows' ability to learn problem-solving techniques by observation and the dominance-dependent pattern in which this technique is transmitted. Crows were allowed to observe one of two box-opening behaviours performed by a dominant or subordinate (...) demonstrator and then tested regarding action and technique. The observers successfully opened the box on their first attempts by using non-matching actions but matching techniques to those observed, suggesting emulation. In the subsequent test sessions, dominant observers (i.e. those dominant to the bird acting as demonstrator) consistently used the learned technique, whereas subordinates (i.e. those subordinate to the bird acting as demonstrator) learned alternative techniques by explorative trial and error. Our findings demonstrate crows' capacity to learn by observing behaviours and the effect of dominance on transmission patterns of behavioural skills. Keywords: social learning; imitation; emulation; affordance; culture; innovation. (shrink)

The places where humans meet other animals matter. This is especially true when considering encounters with animals in captivity. Myriad factors come into play in these instances, not the least of which involve the physical structures of each place and the kinds of organized activities that are offered, encouraged or discouraged there. Motivated by a strong desire to get up close to a dolphin, many people seek out tourism activities offering opportunities to "swim with dolphins." But what is the nature (...) of these swim-with-dolphin programs and how are they actually experienced by participants? If people are seeking genuine, spontaneous contact with a dolphin, does the place and activity of encounter make a .. (shrink)

In the present paper we address the issue of the role of the body in shaping our basic self-awareness. It is generally taken for granted that basic bodily self-awareness has primarily to do with proprioception. Here we challenge this assumption by arguing from both a phenomenological and a neurophysiological point of view that our body is primarily given to us as a manifold of action possibilities that cannot be reduced to any form of proprioceptive awareness. By discussing the notion of (...) affordance and the spatiality of the body we show that both have to be construed in terms of the varying range of our power for action. Finally, we posit that the motor roots of our bodily self-awareness shed new light on both the common ground for and the distinguishing criterium between self and other. The properties of the mirror mechanism indicate that the same action possibilities constituting our bodily self also allow us to make sense of other bodily selves inasmuch as their action possibilities can be mapped onto our own ones. Our proposal may pave the way towards a general deconstruction of the different layers at the core of our full-fledged sense of self and others. (shrink)

Metacognition is associated with planning, monitoring, evaluating and repairing performance Designers of elearning systems can improve the quality of their environments by explicitly structuring the visual and interactive display of learning contexts to facilitate metacognition. Typically page layout, navigational appearance, visual and interactivity design are not viewed as major factors in metacognition. This is because metacognition tends to be interpreted as a process in the head, rather than an interactive one. It is argued here, that cognition and metacognition are part (...) of a continuum and that both are highly interactive. The tenets of this view are explained by reviewing some of the core assumptions of the situated and distribute approach to cognition and then further elaborated by exploring the notions of active vision, visual complexity, affordance landscape and cue structure. The way visual cues are structured and the way interaction is designed can make an important difference in the ease and effectiveness of cognition and metacognition. Documents that make effective use of markers such as headings, callouts, italics can improve students’ ability to comprehend documents and ‘plan’ the way they review and process content. Interaction can be designed to improve ‘the proximal zone of planning’ – the look ahead and apprehension of what is nearby in activity space that facilitates decisions. This final concept is elaborated in a discussion of how e-newspapers combine effective visual and interactive design to enhance user control over their reading experience. (shrink)

The idea that dreams function as fright-simulations rests on the adaptionist notion that anything that has form has function, and psychological argument relies on the mentalist assumption that dream reports are accurate reports of experienced events. Neither assumption seems adequately supported by the evidence presented. [Revonsuo].

Virtual environment landmarks are essential in wayfinding: they anchor routes through a region and provide memorable destinations to return to later. Current virtual environment browsers provide user interface menus that characterize available travel destinations via landmark textual descriptions or thumbnail images. Such characterizations lack the depth cues and context needed to reliably recognize 3D landmarks. This paper introduces a new user interface affordance that captures a 3D representation of a virtual environment landmark into a 3D thumbnail, called a worldlet. (...) Each worldlet is a miniature virtual world fragment that may be interactively viewed in 3D, enabling a traveler to gain first-person experience with a travel destination. In a pilot student conducted to compare textual, image, and worldlet landmark representations within a wayfinding task, worldlet use significantly reduced the overall travel time and distance traversed, virtually eliminating unnecessary backtracking.

After identifying similarities in the paradigmatic problems of biorobotics and ecological psychology, we suggest a way to compare the performance of robots with that of their biological targets. The crucial comparison is between the intentional dynamics of the robot and those of the targeted animal, a measure that depends critically on recognizing and describing the underlying affordance-effectivity match of the target system.

In two shocking articles that appeared in 1968 and 1974, Garrett Hardin argued that the population explosion was producing a “tragedy of the commons.” Since we lack an effective method of sharing common resources, the strong incentive for individuals to appropriate them selfishly would soon lead to their collapse. To mitigate this danger, Hardin proposed a “lifeboat ethic”: less populated and -polluted Western countries should deny food aid to developing nations, where it would save lives only to increase population pressure, (...) and they should close their borders to immigration to prevent their lifeboats from becoming overcrowded and going down with the rest. This paper challenges and complicates Hardin’s account of the tragedy. While there is something right about his view, its vulnerability to a series of empirical challenges reflects its conceptual limitations. I argue that we need to develop a broadly ethical and arguably religious solution to the twin challenges of population growth and pollution. If the liberal commitment to negative freedom is, ironically, largely responsible for our current ecological bind, our only hope of escape is to build bridges between traditions in search of a thicker sense of ethicopolitical obligation.

Valuation consists in a positive or negative response by a subject S to an entity X. Any positive or negative response has a structure that involves a cognitive and a non-cognitive component, as well as a reason relationship between these. This structure is shown to be present in the explicit value judgement 'Hans is a kraut', and then also pointed out in the reflex-like feeding behaviour of a frog, where S treats X as providing an affordance. The conclusion is (...) that valuation need not involve mental states. The article ends with a discussion of the elusive question: what makes a response positive or negative? (shrink)

The initial stage for the discussion is the distinction between bona fide and fiat objects drawn by Barry Smith and collaborators in the context of formal ontology. This paper aims at both producing a rationale for introducing a hitherto unrecognized kind of object—here called ‘Interactive Fiat Objects’ (IFOs)—into the ontology of objects, and casting light on the relationship between embodied cognition and interactive ontology with the aid of the concepts of affordance and ad hoc category. I conclude that IFOs (...) are similar to fiat objects, affordances and ad hoc categories in a number of ways, yet they differ from these in important respects. Interaction is key to understanding the existence and peculiarities of IFOs. By adopting an embodied perspective on cognition, we can enrich our ontological typologies and highlight relevant features of our physical and symbolic environment that are otherwise overlooked. This should improve our understanding of object ontology and persuade us to include IFOs in our metaphysical inventories. (shrink)

Catholic healthcare institutions live amidst tension between three intersecting primary values, namely, a commitment of service to the poor and vulnerable, promoting the common good for all, and financially sustainability. Within this tension, the question sometimes arises as to whether it is ever justifiable, i.e., consistent with Catholic identity, to place limits on charity care. In this article we will argue that the health reform measures of the Affordable Care Act do not eliminate this tension but actually increase the urgency (...) of addressing it. Moreover, we will conclude that the question of limiting charity care in a manner that is consistent with the obligations of Catholic identity around serving the poor and vulnerable, promoting the common good, and remaining financially sustainable is not a question of if, but of how such limits are established. Such limits, however, cannot be established in light of one overriding moral consideration or principle, but must be established in light of a multitude of principles guiding us to a holistic understanding of the interrelatedness of the moral dimensions of Catholic identity.

The notion of culture implies the relative stability of sets of algorithms that become entrenched in human brains as children become socialized, and, to a lesser extent, when immigrants become assimilated into a new society. The semiotics of culture has used the notion of signs and systems of signs to conceptualize this process, which takes for granted memory as a natural affordance of the brain without raising the question of how and why cultural signs impact behaviour in a durable (...) manner. Indeed, under the influence of structuralism, the semiotics of culture has mostly achieved synchronic descriptions. Dynamic models have been proposed to account for the action of signs (e.g., semiosis, dialogism, dialectic) and their resulting cultural changes and cultural diversity. However, these models have remained remarkably abstract, and somewhat disconnected from the actual brain processes, which must be assumed to be involved in the emergence, maintenance, and transformations of cultures. Semiotic terminology has contributed to a systematic representation of cultural objects and processes but thephilosophical origin of its basic concepts has made it difficult to construct a productive interface with the cognitive neurosciences as they have developed and achieved notable advances in the understanding of memory over the last few decades. The purpose of this paper is to suggest that further advances in semiotics will require a shift from philosophical and linguistic notions toward biological and evolutionary models. (shrink)

Francis Bacon's experimental philosophy is discussed, and the way in which it not only shapes scientific methodology but also deeply pervades all philosophical and social learning. Bacon draws us in to participate in an experiment with experience. The central driving force is the idea that learning how to learn is necessary in order to know. To meet this requirement, he considers the relation of form and content of pivotal importance, and therefore the selection of the literary form and the form (...) of data inscription is decisive in the construction of a heuristic tool. His inductive method serves a dual purpose: first, the so-called indicative form aims at securing knowledge by a comprehensible procedure that controls and guides hypothetical thinking. Second, the literary forms "fragment" and "aphorism" embody the subjunctive, and invite intellectual openness and even speculation. In this article, special emphasis is put on Bacon's use and justification of the aphorism. Bacon's pervasive experimentalism meets in some sense today's broad adoption of the experimental mode. His philosophy calls for an ontology that is also at work in recent notions of co-action and co-working, or of affordance. (shrink)

In everyday life we often act adequately, yet without deliberation. For instance, we immediately obtain and maintain an appropriate distance from others in an elevator. The notion of normativity implied here is a very basic one, namely distinguishing adequate from inadequate, correct from incorrect, or better from worse in the context of a particular situation. In the first part of this paper I investigate such ‘situated normativity’ by focusing on unreflective expert action. More particularly, I use Wittgenstein’s examples of craftsmen (...) (tailors and architects) absorbed in action to introduce situated normativity. Situated normativity can be understood as the normative aspect of embodied cognition in unreflective skillful action. I develop Wittgenstein’s insight that a peculiar type of affective behaviour, ‘directed discontent’, is essential for getting things right without reflection. Directed discontent is a reaction of appreciation in action and is introduced as a paradigmatic expression of situated normativity. In the second part I discuss Wittgenstein’s ideas on the normativity of what he calls ‘blind’ rule-following and the ‘bedrock’ of immediate action. What matters for understanding the normativity of (even ‘blind’) rule-following, is not that one has the capacity for linguistic articulation or reflection but that one is reliably participating in a communal custom. In the third part I further investigate the complex relationships between unreflective skillful action, perception, emotion, and normativity. Part of this entails an account of the link between normativity at the level of the expert’s socio-cultural practice and the individual’s situated and lived normativity. (shrink)

This thesis has two main goals: (1) to argue that myths are natural products of human cognition; and (2) that structuralism, as introduced by Claude Levi-Strauss, provides an over-arching theory of myth when supplemented and supported by current research in philosophy of mind, cognitive psychology, and cognitive anthropology. With regard to (1), we argue that myths are naturally produced by the human mind through individuals’ interaction with their natural and social environments. This interaction is constrained by both the type of (...) body the individual has and the environment in which the individual is situated. From this interaction, we argue, is produced the human-body metaphor which plays an essential role in forming analogical mental models which humans use to navigate, predict, and think about their environment(s). With regard to (2), we argue that these analogical mental models are the structures from which myths are created, just as structural anthropology suggests. (shrink)

This discussion paper proposes that a meaningful distinction between science and technoscience can be found at the level of the objects of research. Both notions intermingle in the attitudes, intentions, programs and projects of researchers and research institutions—that is, on the side of the subjects of research. But the difference between science and technoscience becomes more explicit when research results are presented in particular settings and when the objects of research are exhibited for the specific interest they hold. When an (...) experiment is presented as scientific evidence which confirms or disconfirms a hypothesis, this agrees with traditional conceptions of science. When organic molecules are presented for their capacity to serve individually as electric wires that carry surprisingly large currents, this would be a hallmark of technoscience. Accordingly, we propose research on the ontology of research objects. The focus on the character and significance of research objects makes this a specifically philosophical project. (shrink)

I approach the philosophical analyses of the phenomenon of trust vis-à-vis online communication beginning with an overview from within the framework of computer-mediated communication (CMC) of concerns and paradigmatic failures of trust in the history of online communication. I turn to the more directly philosophical analyses of trust online by first offering an introductory taxonomy of diverse accounts of trust that have emerged over the past decade or so. In the face of important objections to the possibility of establishing and (...) fostering trust in online environments—objections that emerge especially from the perspective of virtue ethics and phenomenological approaches to how we know and navigate the world as embodied beings—I then take up three major arguments in recent work in favor of the possibilities of trust online, followed by three vicious circles that run counter to more optimistic views. I close with a summary of some additional reasons for optimism regarding trust online, followed by a final question that emerges out of recent CMC research on social networking sites that poses, I argue, fundamental challenges indeed to how we understand and may foster and experience trust online.

In previous work I urged that the perceptual experience we rational animals enjoy is informed by capacities that belong to our rationality, and - in passing - that something similar holds for our intentional action. In his Presidential Address, Hubert Dreyfus argued that I thereby embraced a myth, "the Myth of the Mental". According to Dreyfus, I cannot accommodate the phenomenology of unreflective bodily coping, and its importance as a background for the conceptual capacities exercised in reflective intellectual activity. My (...) paper responds to this accusation. Dreyfus misreads my invocation of Aristotle, and is thereby led to suppose, wrongly, that I conceive rationality as detached, brought to bear on practical predicaments from a standpoint other than one of immersion in them. I urge that even unreflective bodily coping, on the part of rational animals, is informed by their rationality. Dreyfus mentions Heidegger's distinction, which is picked up by Gadamer, between being oriented towards the world and merely inhabiting an environment. But he sets it aside, whereas it is crucial for the issue between us. Engaged bodily coping involves responsiveness to affordances, and responsiveness to affordances on the part of rational animals belongs to their relation to the world. I explain how the idea that conceptual capacities are actualized in our perceptual experience is connected with the thought that our perceptual experience opens us to the world. Finally, I suggest that the real myth in this area is the conception of rationality underlying Dreyfus's resistance to my picture. (shrink)

This article is about the special, subjective concepts we apply to experience, called “phenomenal concepts”. They are of special interest in a number of ways. First, they refer to phenomenal experiences, and the qualitative character of those experiences whose metaphysical status is hotly debated. Conscious experience strike many philosophers as philosophically problematic and difficult to accommodate within a physicalistic metaphysics. Second, PCs are widely thought to be special and unique among concepts. The sense that there is something special about PCs (...) is very closely tied up with features of the epistemic access they afford to qualia. When we deploy phenomenal concepts introspectively to some phenomenally conscious experience as it occurs, we are said to be acquainted with our own conscious experiences. Accounts of PCs either have to explain the acquaintance relation, or acquaintance with our phenomenal experiences has to be denied. PCs have received much attention in recent philosophy of mind mainly because they figure in arguments for dualism and in physicalist responses to these arguments. The main topic of this article is to explore different accounts of phenomenal concepts and their role in recent debates over the metaphysical status of phenomenal consciousness. (shrink)

Compatibilists often think they can afford to be complacent with regard to scientific findings. But there are apparent threats to free will besides determinism. Robert Kane has recently claimed that if consciousness does not initiate action, all accounts of free will go down, compatibilist and incompatibilist. Some cognitive scientists argue that in fact consciousness does not initiate action. In this paper I argue that they are right (though not for the reasons they advance): as a matter of fact consciousness does (...) not initiate action. But, I contend, Kane is wrong in thinking that it follows that we have no free will. I sketch how we might have free will in spite of the finding that consciousness does not initiate action, and remark on the implications for several well-known accounts of responsibility, include Clarke's agent-causal theory and Fischer and Ravizza's reasons-responsiveness account.

The subject of this paper, Excuses, is one not to be treated, but only to be introduced, within such limits. It is, or might be, the name of a whole branch, even a ramiculated branch, of philosophy, or at least of one fashion of philosophy. I shall try, therefore, first to state what the subject is, why it is worth studying, and how it may be studied, all this at a regrettably lofty level: and then I shall illustrate, in more (...) congenial but desultory detail, some of the methods to be used, together with their limitations, and some of the unexpected results to be expected and lessons to be learned. Much, of course, of the amusement, and of the instruction, comes in drawing the coverts of the microglot, in hounding down the minutiae, and to this I can do no more here than incite you. But I owe it to the subject to say, that it has long afforded me what philosophy is so often thought, and made, barren of -- the fun of discovery, the pleasures of co-operation, and the satisfaction of reaching agreement.
