Ecological psychology has maintained that perception is a process in which the action of the subject and the physical features of the environment converge. The opportunities for action (affordances) perceived by a person depend on the interaction between subject and environment. However, perceiving certain affordances can be conditioned by the norms that govern our social practices: the unjust norms related to an unprivileged identity group can limit the set of affordances available for the people of that group.

Human behavior is an underlying cause for many of the ecological crises faced in the 21st century, and there is no escaping from the fact that widespread behavior change is necessary for socio-ecological systems to take a sustainable turn. Whilst making people and communities behave sustainably is a fundamental objective for environmental policy, behavior change interventions and policies are often implemented from a very limited non-systemic perspective. Environmental policy-makers and psychologists alike often reduce cognition ‘to the brain,’ focusing only to (...) a minor extent on how everyday environments systemically afford pro-environmental behavior. Symptomatic of this are the widely prevalent attitude–action, value–action or knowledge–action gaps, understood in this paper as the gulfs lying between sustainable thinking and behavior due to lack of affordances. I suggest that by adopting a theory of affordances as a guiding heuristic, environmental policy-makers are better equipped to promote policies that translate sustainable thinking into sustainable behavior, often self-reinforcingly, and have better conceptual tools to nudge our socio–ecological system toward a sustainable turn. Affordance theory, which studies the relations between abilities to perceive and act and environmental features, is shown to provide a systemic framework for analyzing environmental policies and the ecology of human behavior. This facilitates the location and activation of leverage points for systemic policy interventions, which can help socio–ecological systems to learn to adapt to more sustainable habits. Affordance theory is presented to be applicable and pertinent to technically all nested levels of socio–ecological systems from the studies of sustainable objects and households to sustainable urban environments, making it an immensely versatile conceptual policy tool. Finally, affordance theory is also discussed from a participatory perspective. Increasing the fit between local thinking and external behavior possibilities entails a deep understanding of tacit and explicit attitudes, values, knowledge as well as physical and social environments, best gained via inclusive and polycentric policy approaches.

In this paper we introduce the device perspective as a methodological contribution to platform studies. Through an engagement with debates about the notion of affordances, which focus on the relation between the technical and the social, we put forward an approach to study the production of data within platforms by engaging with the material properties of platforms as well as their interpretation and deployment by various types of users. As a case in point, we study how the affordances (...) of Wikipedia are deployed in the production of encyclopedic knowledge and how this can be used to study controversies. The analysis shows how Wikipedia affords unstable encyclopedic knowledge by having mechanisms in place that suggest the continuous negotiation of existing knowledge. We furthermore showcase the use of our open-source software, Contropedia, which can be utilized to study knowledge production on Wikipedia. (shrink)

What are the affordances of artifacts? One view is that the affordances of artifacts, just as the affordances of natural objects, pertain to possible ways in which they can be manipulated. Another view maintains that, given that artifacts are sociocultural objects, their affordances pertain primarily to their culturally-derived function. Whereas some have tried to provide a unifying notion of affordance to capture both aspects, here I argue that they should be kept separate. In this paper, I (...) introduce a distinction between standard affordances, which concern the function of artifacts, and ad-hoc affordances, which refer to how artifacts are manipulated. I then argue for the neuropsychological plausibility of such a distinction, linking it to the dissociation between function knowledge and manipulation knowledge. Finally, I defend the equal status of these forms of knowledge and, hence, of standard and ad-hoc affordances, and I show that this has some implications for the debate on the role of motor processes in the conceptual knowledge of artifacts.

Many of our sources of knowledge only afford us knowledge that is inexact. When trying to see how tall something is, or to hear how far away something is, or to remember how long something lasted, we may come to know some facts about the approximate size, distance or duration of the thing in question but we don’t come to know exactly what its size, distance or duration is. In some such situations we also have some pointed (...) class='Hi'>knowledge of how inexact our knowledge is. That is, we can knowledgeably pinpoint some exact claims that we do not know. We show that standard models of inexact knowledge leave little or no room for such pointed knowledge. We devise alternative models that are not afflicted by this shortcoming. (shrink)

A word of warning concerning the aims of this volume is in order. Other wise some readers might be unpleasantly surprised by the fact that two of the chapters of an ostensibly historical book are largely topical rather than historical. They are Chapters 7 and 9, respectively entitled 'Are Logical Truths Analytic?' and 'A Priori Truths and Things-In-Them selves'. Moreover, the history dealt with in Chapter 11 is so recent as to have more critical than antiquarian interest. This mixture of (...) materials may seem all the more surprising as I shall myself criticize (in Chapter I) too facile assimilations of earlier thinkers' concepts and problems to later ones. There is no inconsistency here, it seems to me. The aims of the present volume are historical, and for that very purpose, for the purpose of understanding and evaluating earlier thinkers it is vital to know the conceptual landscape in which they were moving. A crude analogy may be helpful here. No military historian can afford to neglect the topo graphy of the battles he is studying. If he does not know in some detail what kind of pass Thermopylae is or on what sort of ridge the battle of Bussaco was fought, he has no business of discussing these battles, even if this topographical information alone does not yet amount to historical knowledge.

Many urgent problems that societies currently face—from climate change to a global pandemic—require citizens to engage with scientific information as members of democratic societies as well as to solve problems in their personal lives. Most often, to solve their epistemic aims (aims directed at achieving knowledge and understanding) regarding such socio-scientific issues, individuals search for information online, where there exists a multitude of possibly relevant and highly interconnected sources of different perspectives, sometimes providing conflicting information. The paper provides a (...) review of the literature aimed at identifying (a) constraints and affordances that scientific knowledge and the online information environment entail and (b) individuals' cognitive and motivational processes that have been found to hinder, or conversely, support practices of engagement (such as critical information evaluation or two-sided dialogue). Doing this, a conceptual framework for understanding and fostering what we callonline engagement with scientific informationis introduced, which is conceived as consisting of individual engagement (engaging on one's own in the search, selection, evaluation, and integration of information) and dialogic engagement (engaging in discourse with others to interpret, articulate and critically examine scientific information). In turn, this paper identifies individual and contextual conditions for individuals' goal-directed and effortful online engagement with scientific information. (shrink)

According to a standard assumption in epistemology, if one only partially believes that p , then one cannot thereby have knowledge that p. For example, if one only partially believes that that it is raining outside, one cannot know that it is raining outside; and if one only partially believes that it is likely that it will rain outside, one cannot know that it is likely that it will rain outside. Many epistemologists will agree that epistemic agents are capable (...) of partial beliefs in addition to full beliefs and that partial beliefs can be epistemically assessed along some dimensions. However, it has been generally assumed that such doxastic attitudes cannot possibly amount to knowledge. In Probabilistic Knowledge, Moss challenges this standard assumption and provides a formidable defense of the claim that probabilistic beliefs—a class of doxastic attitudes including credences and degrees of beliefs—can amount to knowledge too. Call this the probabilistic knowledge claim . Throughout the book, Moss goes to great lengths to show that probabilistic knowledge can be fruitfully applied to a variety of debates in epistemology and beyond. My goal in this essay is to explore a further application for probabilistic knowledge. I want to look at the role of probabilistic knowledge within a “knowledge-centered” psychology—a kind of psychology that assigns knowledge a central stage in explanations of intentional behavior. My suggestion is that Moss’s notion of probabilistic knowledge considerably helps further both a knowledge-centered psychology and a broadly intellectualist picture of action and know-how that naturally goes along with it. At the same time, though, it raises some interesting issues about the notion of explanation afforded by the resulting psychology. (shrink)

Many philosophers believe that aesthetic testimony can provide aesthetic knowledge. This leaves us with the question: why does getting aesthetic knowledge by experience – by seeing a painting up close, or witnessing a performance first-hand – nevertheless seem superior to aesthetic testimony? I argue that it is due to differences in their epistemic value; in the diversity of epistemic goods each one provides. Aesthetic experience, or the experience of art or other aesthetic objects, affords multiple, distinctive epistemic goods (...) whereas aesthetic testimony affords less. In particular, it provides aesthetic knowledge of truths, a kind of propositional knowledge, as well as aesthetic knowledge of things, a kind of non-propositional knowledge. Although aesthetic experience is superior because it has more epistemic value, this doesn’t mean that aesthetic testimony provides weaker justification for aesthetic belief than aesthetic experience; the difference is evaluative, not normative. In this way, we can explain a key pessimistic intuition about aesthetic testimony – that it is inferior to aesthetic experience – whilst preserving the optimistic view that aesthetic testimony makes aesthetic knowledge available to others. The superior epistemic value of first-hand aesthetic experience is compatible with a number of important observations about aesthetic testimony, including the importance of aesthetic trust. (shrink)

Open peer commentary on the article “I Can’t Yet and Growth Mindset” by Fiona Murphy & Hugh Gash.: When a student changes to a growth mindset, a new set of affordances becomes available for that student. In my commentary, I discuss how Murphy and Gash’s approach to influencing both teacher’s and students’ beliefs about learning differs from the more prevalent and traditional approach based on the idea of transmission of knowledge. Then I consider how this approach to reflexivity (...) is relevant to bringing about change in schools, in teacher education, and in other settings. (shrink)

Sarah Moss argues that degrees of belief, or credences, can amount to knowledge in much the way that full beliefs can. This essay explores a new kind of objective Bayesianism designed to take us some way toward securing such knowledge-constituting credences, or "probabilistic knowledge." Whatever else it takes for an agent's credences to amount to knowledge, their success, or accuracy, must be the product of _cognitive ability_ or _skill_. The brand of Bayesianism developed here helps ensure (...) this ability condition is satisfied. Cognitive ability, in turn, helps make credences valuable in other ways: it helps mitigate their dependence on epistemic luck, for example. What we end up with, at the end of the day, are credences that are particularly good candidates for constituting probabilistic knowledge. What's more, examining the character of these credences teaches us something important about what the pursuit of probabilistic knowledge demands from us. It does _not_ demand that we give hypotheses equal _treatment_, by affording them equal credence. Rather, it demands that we give them equal _consideration_, by affording them an equal chance of being discovered. (shrink)

Despite the accumulation of substantial cognitive science research relevant to education, there remains confusion and controversy in the application of research to educational practice. In support of a more systematic approach, we describe the Knowledge-Learning-Instruction (KLI) framework. KLI promotes the emergence of instructional principles of high potential for generality, while explicitly identifying constraints of and opportunities for detailed analysis of the knowledge students may acquire in courses. Drawing on research across domains of science, math, and language learning, we (...) illustrate the analyses of knowledge, learning, and instructional events that the KLI framework affords. We present a set of three coordinated taxonomies of knowledge, learning, and instruction. For example, we identify three broad classes of learning events (LEs): (a) memory and fluency processes, (b) induction and refinement processes, and (c) understanding and sense-making processes, and we show how these can lead to different knowledge changes and constraints on optimal instructional choices.

I argue that Bartolomé de las Casas and Juan Ginés de Sepúlveda differed in their conclusions regarding the status of Indigenous persons at least partly because las Casas had significant, yet incomplete, understanding of Indigenous persons, culture and societies and Sepúlveda had mere knowledge of them. To this end, I show that the epistemic state of understanding explains why Las Casas properly concluded that Indigenous persons deserve the same moral status afforded to Europeans. And I show how las Casas’ (...) understanding of Indigenous persons, culture and societies related to what he got wrong about Indigenous persons. (shrink)

Digital texts have for decades been a challenge for reading research, creating a range of questions about reading and a need for new theories and concepts. In this paper, we focus on materialities of texts and suggest an embodied, enacted, and extended approach to the research on digital reading. We refer to findings showing that cognitive activities in reading are grounded in bodily and social experiences, and we explore the cognitive role of the body in reading, claiming that–influenced by tacit (...) knowledge and the task at hand–textual meaning is enacted through a mental and physical engagement with text. Further, applying the concept of affordances, we examine how digital technologies have induced new ways of physically handling and mentally interpreting text, indicating that brain, body, text, and technologies are integrated parts of an extended process of reading. The aim of the paper is to encourage empirical research on the interplay between body, text, and text materialities, a focus we argue will deepen our understand of the current transformation of reading.

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)

Over the past decades, science funding shows a shift from recurrent block funding towards project funding mechanisms. However, our knowledge of how project funding arrangements influence the organizational and epistemic properties of research is limited. To study this relation, a bridge between science policy studies and science studies is necessary. Recent studies have analyzed the relation between the affordances and constraints of project grants and the epistemic properties of research. However, the potentially very different affordances and constraints (...) of funding arrangements such as awards, prizes and fellowships, have not yet been taken into account. Drawing on eight case studies of funding arrangements in high performing Dutch research groups, this study compares the institutional affordances and constraints of prizes with those of project grants and their effects on organizational and epistemic properties of research. We argue that the prize case studies diverge from project-funded research in three ways: 1) a more flexible use, and adaptation of use, of funds during the research process compared to project grants; 2) investments in the larger organization which have effects beyond the research project itself; and 3), closely related, greater deviation from epistemic and organizational standards. The increasing dominance of project funding arrangements in Western science systems is therefore argued to be problematic in light of epistemic and organizational innovation. Funding arrangements that offer funding without scholars having to submit a project-proposal remain crucial to support researchers and research groups to deviate from epistemic and organizational standards.

The Platonic view that art is incapable of providing us with knowledge is sufficiently widely held as to merit a serious attempt at refutation. Once it is acknowledged that there are alternative forms of knowledge other than propositional, then it is possible to establish the truth of the claim that the knowledge which art affords has a value on a par with that provided by other disciplines. Art, it is argued, has a unique potential to provide imaginative (...) insights by reference to which we may understand what it is like to experience and to feel, in ways very different from those with which we may be familiar. It is shown to be instrumental in enabling us to refine our moral concepts as well as in determining what is salient from the moral point of view. As a powerful tool in the education of the emotions, artworks have the power to increase our moral sensitivity and to sharpen our perception of what is required of us inways that are otherwise unobtainable.

Purpose While online classes have enabled many universities to carry out their regular academic activities, they have also given rise to new and unanticipated ethical concerns. We focus on the “dark side” of online class settings and attempt to illuminate the ethical problems associated with them. The purpose of this study is to investigate the affordances stemming from the technology-user interaction that can result in negative outcomes. We also attempt to understand the context in which these deleterious affordances (...) are actualized. Design/methodology/approach We obtain the data from narratives written by students at a top private university in Bangladesh about their experiences of online classes and exams and from focus group discussions with them. We use the lens of affordance theory to identify the abilities that goal-oriented actors – primarily students – obtain from the technology-user interactions, which result in negative outcomes. We also attempt to understand the contextual actualization of those affordances through the lens of Routine Activity Theory (RAT). Findings We find three deleterious affordances and three associated deviant outcomes. Non-monitorability which results in academic dishonesty, disguiseability which results in cyber-truancy, and intrudeability which results in embarrassment and harassment. Our findings reveal a deeper underlying problem with the existing educational approach in the universities of Bangladesh and suggest that there is a need to introduce more modern teaching techniques focused on issues such as student engagement and interactive learning. Originality/value To the best of our knowledge, this is the first paper that combines affordance theory with RAT to identify unethical practices observed in online class settings in the context of a least developed country like Bangladesh and to examine the environmental components that give rise to the pre-conditions for the unethical practices to surface.

What chemists take as molecular structure is a theoretical construct based on the concepts of chemical bond, atoms in molecules, etc. and hence it should be distinguished from tangible structures around us.

But it is not derived a priori from quantum mechanical treatments of the molecule and criticized for being irrelevant to the reality of the molecule. There is persistent skepticism about it. The (...) present study aims to overcome this skepticism by having recourse to the concepts of affordance and phenomenal field. The basic idea of our approach is suggested by the following statement of Niels Bohr: ‘evidence obtained under different experimental conditions cannot be comprehended within a single picture but must be regarded as complementary in the sense that only the totality of the phenomena exhausts the possible information about the objects’. This implies that we should take account of a context in which the cognition of a fact arises when we think about human activities including science. This can be realized by invoking affordances of a complex such as {agent, devices, methods, substances, surroundings}. That is to say, affordances are context-relative dispositional attributes of {agent-material world} complexes as is asserted by Harré and Llored. The phenomenal field is a conceptual device which schematizes the contextual aspect of affordance and, more importantly, serves as a link between the concept of affordance and Kant’s theory of knowledge, by which alone affordances are realized as the dispositional properties of {agent-material world} complexes. Because affordances become actualized in various phenomenal fields, affordances of one and the same object may well be distinct from one another. In conclusion we can take that molecular structure is the affordance of a complex that includes a chemist who is engaged in organic synthesis, whereas a quantum mechanical picture of the molecule may be one of the possible affordances of a complex that includes a quantum chemist who cares about electronic states of the molecule.

John Hawthorne’s recent monograph Knowledge and Lotteries1 is centred on the following puzzle: Suppose you claim to know that you will not be able to afford to summer in the Hamptons next year.

Most of us have the intuition that you do not know that your ticket is a loser. However, (...) your alleged knowledge of not being able to afford to summer in the Hamptons puts you in a position to know that your ticket is a loser. For the proposition that you will not be able to afford to summer in the Hamptons entails the proposition that you will lose the lottery. And the following principle, what Hawthorne calls ‘Single Premise Closure’ ( p. 34), is very plausible: If you know that p, p entails q, and you competently deduce q from p thereby coming to believe that q (all the while retaining your knowledge of p), then you come to know q.

Social media is a prominent communication platform. Its active usage permeates all generations and it is imperative that the platform be fully optimized for knowledge transfer and innovation diffusion. However, there are several considerations regarding platform usage, including media affordances. Social media affordances enable users to interact with the world around them through features of modality, agency, interactivity, and navigation. Previous studies have indicated that social media affordances significantly influence user behavior and usage. However, research exploring (...) the effect of social media affordances on knowledge acquisition and the reduction of decision-making complexities is limited. Therefore, focusing on 179 paddy farmers in Malaysia, this study examined the effect of social media affordances on information quality, knowledge acquisition, and complexity reduction regarding innovation adoption decisions using a quantitative approach. This study’s findings reveal that social media affordances have a significant effect on perceived information quality, knowledge acquisition, and complexity reduction. (shrink)

Digital social analytics is a subset of Big Data methods that is used to understand the social environment in which people and organizations have to act. This paper presents an analysis of eight projects that are experimenting with the use of these methods for various purposes. It shows that two specific technological features influence the work with such methods in all the cases. The first concerns the need to distribute choices about the structure of data to third-party actors and the (...) second concerns the need to balance machine intelligence and human intuition when automating the analysis. These features set specific conditions for knowledge production, and the paper identifies two opposite approaches for engaging with each of these conditions. These features and approaches are finally combined into a two-dimensional affordance space that illustrates how there is flexibility in the way project leaders interact with the features of the data environment. It thereby also shows how digital social analytics come to have different affordances for different projects. (shrink)

Skilled cooperative action means being able to understand the communicative situation and know how and when to respond appropriately for the purpose at hand. This skill is of the performance of knowledge in co-action and is a form of social intelligence for sustainable interaction. Social intelligence, here, denotes the ability of actors and agents to manage their relationships with each other. Within an environment we have people, tools, artefacts and technologies that we engage with. Let us consider all of (...) these as dynamic representations of knowledge. When this knowledge becomes enacted, i.e., when we understand how to use it to communicate effectively, such that it becomes invisible to us, it becomes knowledge in co-action. A challenge of social intelligence design is to create mediating interfaces that can become invisible to us, i.e., as an extension of ourselves. In this paper, we present a study of the way people use surfaces that afford graphical interaction, in collaborative design tasks, in order to inform the design of intelligent user interfaces. This is a descriptive study rather than a usability study, to explore how size, orientation and horizontal and vertical positioning, influences the functionality of the surface in a collaborative setting.

It is largely agreed that if constructivism contributes anything to meta-ethics it is by proposing that we understand ethical objectivity “in terms of a suitably constructed point of view that all can accept” (Rawls 1980/1999: 307). Constructivists defend this “practical” conception of objectivity in contrast to the realist or “ontological” conception of objectivity, understood as an accurate representation of an independent metaphysical order. Because of their objectivist but not realist commitments, Kantian constructivists place their theory “somewhere in the space between (...) realist and relativist accounts of ethics” (O’Neill 1988: 1). Furthermore, they argue that their practical conception of objectivity succeeds in making sense of certain features of morality, such as its categorical authority and its relation to rational agency, which escape rival theories (Korsgaard 1996b, Korsgaard 2003b). To this extent, constructivism claims a privileged place in meta-ethics. The legitimacy of this claim is widely challenged. Precisely because of its practical conception of objectivity, many – including some constructivists — regard constructivism as a first-order normative theory, rather than as a meta-ethical position, hence not on a par with realism. Some critics object that constructivism fails to offer a distinct meta-ethics because it is structurally incomplete and thus must be combined with a fully-fledged meta-ethics (Hussain and Shah 2006); others argue that it tacitly relies on realism (Timmons 2003; Shafer-Landau 2003; Larmore 2008). Thus far, the debate about the prospects of constructivism as a meta-ethical theory has been driven by the conviction that the case for or against constructivism depends on its ontological commitments. In this chapter, I propose a change in perspective. My aim is to defend constructivism as an objectivist account of practical knowledge. Its defining feature is the claim that practical knowledge is knowledge by principles. Its task is to establish a constitutive relation between knowledge of oneself as a practical subject and knowledge about what one ought to do. By focusing on the issue of practical knowledge I hope to show that the difficulty in situating Kantian constructivism firmly on the meta-ethical map, along with other meta-ethical theories, reflects ambiguities and oscillations about the practical significance of ethics. Even though the term is ambiguous, I retain the qualification “Kantian” for the constructivist theory I outline, and for two reasons. First, while the theory I outline differs from current agnostic or anti-realist variants, it is closer to its origins, since Kant treats practical reason as a cognitive capacity and takes moral judgments to be objective moral cognitions, which importantly differ from other sorts of rational cognitions because they bind us in the first person. Practical cognitions are common knowledge because they are such that all subjects endowed with rationality can arrive at them by reasoning and find them authoritative. Thus understood, Kantian constructivism carves a distinct logical space in the meta-ethical debate that other sorts of constructivism fail to identify. This is the second reason for keeping the qualification “Kantian”. On this formulation, constructivism is antagonistic to non-cognitivist theories denying that moral judgments have cognitive contents, because they deny that there is something to be known; but it is also a rival to cognitivist theories denying that knowledge can be practical in itself. How constructivism differs over the realist theories of practical reason is the least understood aspect of this debate. This essay aims to make the case that practical reason is both discursive and emotional. In contrast to foundational and anti-realist accounts of practical reasoning, it attempts to show that the moral feeling of respect plays a cognitive but non-evidential role in the account of the cognitive and practical powers of reason. The argument proceeds as follows. In section 1, I consider some prominent constructivist arguments against the model of applied knowledge and show that they are driven by non-cognitivist assumptions about the practicality of ethics and the legitimacy of epistemological claims. In section 2, I argue that these arguments do not succeed in disposing of the idea of practical knowledge as incoherent, because they trade on an ambiguity regarding the proper object of practical knowledge. To solve this ambiguity, I turn to Anscombe’s contrast between “practical” and “speculative” knowledge as models for understanding action. I thus suggest that Anscombe’s account of practical knowledge as knowledge of oneself as an agent is an important resource for Kantian constructivism. This finding prompts us to reset the current dispute about the ontological and epistemological commitments of Kantian constructivism, as illustrated in section 3. While constructivism does not postulate any moral ontology prior to reasoning, it attributes to reasoning the cognitive powers to establish a distinctive relation between the agent and her action. The task of sections 4-7 is to account for the distinctive features of Kantian constructivism understood as an objectivist account of practical knowledge. In section 4, I argue that in order for reasoning to accomplish its normative tasks, it should be conceived as a self-legislating activity. I respond to some objections to the idea of self-legislation as the form of rational willing by offering a dialogical view of practical reason. In section 5, I propose a non-standard interpretation of Kant’s argument of “the fact of reason” to show that the constructivist account of self-legislation does not build on realism about value, as its detractors claim. The “basis of construction” is the subjective experience of respect for the self-legislative capacity itself. This moral feeling conveys our awareness of rational agency and shows our responsiveness to the demands of practical reason. It is an emotional mode of practical knowledge of oneself as an agent (in the sense specified in section 2), but not as a mode of moral discernment. In section 6, I show how practical knowledge of oneself as an agent relates to practical knowledge about what one ought to do. I thus account for the relation between respect as emotional moral consciousness and respect as a deliberative constraint. Finally, in section 7, I reply to the objection of subjectivism. I explain how the complex sort of objectivity that Kantian constructivism affords is at the same time more ambitious and more modest than is generally assumed. (shrink)

While knowledge represents a valuable commodity, not all forms of knowledge are afforded equal status. The politics of knowledge, which entails the privileging of particular ways of knowing through linkages between the producers of knowledge and other bearers of authority or influence, represents a powerful force driving knowledge development. Within the health research and practice community, biomedical knowledge (i.e. knowledge pertaining to the biological factors influencing health) has been afforded a privileged position, shaping (...) the health research and practice community's view of health, illness and appropriate intervention. The aim of this study is to spark critical reflection and dialogue surrounding the ways in which the politics of knowledge have constrained progress in addressing mental health and illness, one of today's leading public health issues. I argue that the hegemony of biological knowledge represents an ethical issue as it limits the breadth of knowledge available to support practitioners to ‘do good’ in terms of addressing mental illness. Given the power and influence inherent within the nursing community, I propose that nurses ought to engage in critical reflection and action in an effort to better situate the health research and practice community to effectively address the mental health of populations.

The mental representation of one’s own body does not necessarily correspond to the physical body. For instance, a dissociation between perceived and actual reach-ability has been shown, that is, individuals perceive that they can reach objects that are out of grasp. We presented participants with 3D pictures of objects located at four different distances, namely near-reaching space, actual-reaching space, perceived-reaching space and non-reaching space. Immediately after they were presented with function, manipulation, observation or pointing verbs and were required to judge (...) if the verb was compatible with the object.Participants were faster with function and manipulation verbs than with observation and pointing verbs. Strikingly, with both function and manipulation verbs participants were faster when objects were presented in actual than the perceived reaching space. These findings suggest that our knowledge of the world is implicitly built online through behaviour, and is not necessarily reflected in explicit estimates or conscious representations. (shrink)

We propose a view of embodied representations that is alternative to both symbolic/linguistic approaches and purely sensorimotor views of cognition, and can account for procedural and declarative knowledge manipulation. In accordance with recent evidence in cognitive neuroscience and psychology, we argue that anticipatory and simulative mechanisms, which arose during evolution for action control and not for cognition, determined the first form of representational content and were exapted for increasingly sophisticated cognitive uses. In particular, procedural and declarative forms of (...) class='Hi'>knowledge can be explained, respectively, in terms of on-line sensorimotor anticipation and off-line simulations of potential actions, which can give access to tacit knowledge and make it explicit. That is, mechanisms that evolved for the on-line prediction of the consequences of one's own actions (i.e. forward models) determine a (procedural) form of representation, and became exapted for off-line use. They can therefore be used to produce (declarative) knowledge of the world, by running a simulation of the action that would produce the relevant information. We conclude by discussing how embodied representations afford a form of internal manipulation that can be described as internalized situated action. (shrink)

The ability to judge accurately whether or not an action can be accomplished successfully is critical for selecting appropriate response options that enable adaptive behaviors. Such affordance judgments are thought to rely on the perceived fit between environmental properties and knowledge of one's current physical capabilities. Little, however, is currently known about the ability of individuals to judge their own affordances following a stroke, or about the underlying neural mechanisms involved. To address these issues, we employed a signal (...) detection approach to investigate the impact of left or right hemisphere injuries on judgments of whether a visual object was located within reach while remaining still. Regarding perceptual sensitivity and accuracy in judging reachability, there were no significant group differences between healthy controls, right brain damaged and left brain damaged stroke patients. However, while healthy controls and RBD patients demonstrated a negative response criterion and thus overestimated their reach capability, LBD patients' average response criterion converged to zero, indicating no judgment tendency. Critically, the LBD group's judgment tendency pattern is consistent with previous findings in this same sample on an affordance judgment task that required estimating whether the hand can fit through apertures. Lesion analysis suggests that this loss of judgment tendency may be associated with damage to the left insula, the left parietal and middle temporal lobe. Based on these results, we propose that damage to the left ventro-dorsal stream disrupts the retrieval and processing of a stable criterion, leading to stronger reliance on intact on-line body-perceptive processes computed within the preserved bilateral dorsal network.

In 2013, in accordance with a provision in the Patient Protection and Affordable Care Act, the U.S. government began fining hospitals with “excessive” patient readmission rates. Those working to respond to this issue have identified discharge communication with patients as a critical component. In response to this exigency and to contribute to the conversation in the medical humanities about the field’s purview and orientation, this article analyzes studies of and texts about communication in health and medicine, ultimately arguing that the (...) on-going circulation of compliance rhetoric and assumptions has limited efforts to improve patient communication. The article, furthermore, considers that humanist ideals of agentic action, the patient-centered care movement’s emphasis on the patient, and biomedicine’s tendency to treat evidence-based knowledge as fixed and given may have combined to support a rationale for using patient adherence to treatment guidelines as metrics in measurement studies designed to identify effective communication strategies. Finally, the article proposes that those working in the medical humanities consider the value of interdisciplinary posthumanist scholarship—specifically, its treatment of agency and knowledge as emergent, distributed, and contingent—and its potential to transform or extend in productive ways the conversation about what constitutes effective communication with patients.

It is held that the quality of the working environment afforded to an individual critically affects the health and well-being of that individual. This has consequences for both the quality of work which that individual can actually perform, and for the quality of the society in which that individual has a place. Conceptions of a fit working environment have led to the idea of a human-centred system, and this idea is applicable to the area of knowledge-based systems (KBS). A (...) system structure is discussed, which permits a human-centred approach to be adopted towards KBS design. It is held that the performance of such a system will generally exceed that of unaided KBS operation. (shrink)

The problem of knowledge is generally regarded as an essential part of philosophy, and since the time of Descartes at least, every philosopher has found it necessary to show that his own view can afford a solution to the problem. In this paper, however, the method of approach is psychological rather than philosophical, and an attempt is made to deal with the question from a point of view differing in several respects from those more commonly accepted.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.2 (2002) 354-368 [Access article in PDF] Davidson, Self-knowledge, and Autobiographical Writing Garry Hagberg AMONG THE NUMEROUS THINGS that make any autobiographical undertaking so interesting is the fact that there exists no one-to-one correlation between a person's belief, intention, preference, desire, hope, fear, expectation, and so forth (through a list including many of the diverse things philosophers now tend to group together as propositional attitudes) (...) and that person's behavior. Were there such a relation, our knowledge of others would be far more transparent than it is, and autobiographical writing would prove straightforwardly simple: for each remembered action there would be a determinate mental event that stood behind it, and a recording of the past action by the autobiographer would entail the parallel reporting of the mental predecessor, or indeed cause 1 articulated in terms of the content of a single propositional attitude, of that action.Of course, this simple dualistic schema has been subjected to various forms of scrutiny: Nietzsche decried what he generically termed the "antecendentia of action," 2 referring to the explanatory dreamland many philosophers and other theorists have happily but confusedly occupied, wherein the explanations of "outward" human actions proceed in what we will then call prior inward mental determinants. Focusing on the alleged temporal separation of antecedent and consequent action, Nietzsche with characteristic rhetorical force ridicules the [End Page 354] misled many who attempt to explain something in some cases so complex, and in other cases so immediate, as human intentional action. Ryle, focusing on the dualistic separation of inner and outer in any such explanatory schema, famously argued against the very conceptual substructure of the "ghost in the machine" 3 ; the ensuing behaviorism argued against the inner world of mental machinations, yielding a picture of selfhood that was in retrospect fairly close to and anticipatory of one variety of reductive monism, or "animalism," now argued in some quarters. 4 On any such behavioristic-reductionistic view, the project of the autobiographer would precisely be just to recount past actions, show their relations to other actions both before and after, and give an overarching narrative that displays the shape of a life over time—all without explanatory recourse to ghostly prior causes standing behind, and invariably dualistically linked to, the actions being recounted.Wittgenstein's conceptually reorienting remarks avoided the Scylla of dualism and the Charybdis of behaviorism, 5 and although any summary statement of his position is instructively impossible, it can be said that he showed that the language-games of intentional action are intricately, and with an irreducible complexity, interrelated with the language-games of human behavior and—to speak too generally—action-description. 6 Equipped with the view, or rather overview (Wittgenstein's übersicht), that we might gain of those myriad interrelations between language-games as a result of a consideration of cases (of precisely the kinds psychologically mimetic literature affords), we might outlive our desire to thematically encapsulate the (mythical) unitary nature of the relation between intention and action, and correspondingly free ourselves of a misbegotten picture of autobiographical writing, i.e., the very picture of one-to-one action-causation, and hence of autobiographical truth, mentioned above. But deliverance out of the grip of any such picture, to reemploy Wittgenstein's resonant phrase, is not easily won; it is most assuredly not a simple matter of deciding not to think that way anymore, or of being permanently relieved of any such dualistic misconception as a result of reading a few memorable remarks. The impulses to posit Nietzsche's antecedentia, to believe in Ryle's despised ghosts, to cling to a partially submerged belief that autobiographical writing will, with whatever local variations, fit the generic dualistic mold Wittgenstein labors to undercut, is no more the kind of thing one simply leaves behind any more than one simply drops, upon recognition that it is such, what a Freudian calls a repetition-compulsion. [End Page 355]Thus Donald Davidson writes—and (leaving aside what "truer" means) truer words are rarely spoken—that "there is a picture of the mind which... (shrink)

We propose a new topological semantics for evidence, evidence-based justifications, belief, and knowledge. Resting on the assumption that an agent’s rational belief is based on the available evidence, we try to unveil the concrete relationship between an agent’s evidence, belief, and knowledge via a rich formal framework afforded by topologically interpreted modal logics. We prove soundness, completeness, decidability, and the finite model property for the associated logics, and apply this setting to analyze key epistemological issues such as “no (...) false lemma” Gettier examples, misleading defeaters, undefeated justification versus undefeated belief, as well as the defeasibility theories of knowledge.

In the Nicomachean Ethics Aristotle distinguishes fairly sharply between the practical deliberation of moral virtue and the epistemic reflection of theoretical or truth-focused enquiry. However, drawing on insights from Plato and Iris Murdoch, the present paper seeks a more robust epistemic foundation for virtuous deliberation as primarily grounded in clear or correct perception of the world and human association, character and conduct. While such perception may not be sufficient for moral virtue, it is here argued that it is necessary. Murdoch's (...) view that literature may afford especially effective correction of moral misperception is also supported by appeal to literary examples. (shrink)

This interesting and challenging book addresses the apparent gap between the empiricist account of the origin of ideas and the theory of knowledge in the Essay concerning Human Understanding.

Much has been written about Husserl and the famous problems of intersubjectivity and solipsism, and some work has been done regarding Husserl's notion of empathy and its role in the establishment of intersubjectivity. The vast majority of that work, however, focuses on one of Husserl's texts and on the establishment of the possibility of other subjects. What is lacking in the scholarship is an investigation of the role of empathy in Husserl's corpus which address the related issues: validity, the degrees (...) of evidence with which something can be experienced, the different senses of "objective" in Husserl's texts, whether empathy contributes to knowledge or just to the validity of one's knowledge, where in the empathetic-communicative process something becomes objective. This dissertation begins to fill that gap by offering an investigation of the role of empathy in the attainment of objectively valid knowledge in each of Husserl's three introductions to phenomenology: Ideas: A General Introduction to Pure Phenomenology , Cartesian Meditations: An Introduction to Phenomenology , and The Crisis of European Sciences and Transcendental Phenomenology: An Introduction to Phenomenological Philosophy . ;Despite accusations by commentators that Husserl's is a solipsistic philosophy, I show that empathy is related to one's knowledge on the view offered in each of Husserl's introductions to phenomenology. Empathy is significantly related to knowledge in at least two ways and Husserl's epistemology might, consequently, be called a social epistemology: empathy helps to offer evidence for validity and thus solidify one's knowledge and it helps to broaden one's knowledge by affording the ability to gain access to what others have constituted and known. These roles of empathy are not at odds with one another; rather, both are at play in each of the introductions and, given his position in the earlier work, Husserl needed to expand the role of empathy as he did. Such a reliance on empathy, however, calls into question whether Husserl's is a transcendental philosopher in the sense Husserl claimed it is. (shrink)

Objective Adolescents have had very limited access to research on biomedical prevention interventions despite high rates of HIV acquisition. One concern is that adolescents are a vulnerable population, and trials carry a possibility of harm, requiring investigators to take additional precautions. Of particular concern is preventive misconception, or the overestimation of personal protection that is afforded by enrolment in a prevention intervention trial. Methods As part of a larger study of preventive misconception in adolescent HIV vaccine trials, we interviewed 33 (...) male and female 16–19-year-olds who have sex with men. Participants underwent a simulated HIV vaccine trial consent process, and then completed a semistructured interview about their understanding and opinions related to enrolment in a HIV vaccine trial. A grounded theory analysis looked for shared concepts, and focused on the content and process of adolescent participants’ understanding of HIV vaccination and the components of preventive misconception, including experiment, placebo and randomisation. Results Across interviews, adolescents demonstrated active processing of information, in which they questioned the interviewer, verbally worked out their answers based upon information provided, and corrected themselves. We observed a wide variety of understanding of research concepts. While most understood experiment and placebo, fewer understood randomisation. All understood the need for safer sex even if they did not understand the more basic concepts. Conclusions Education about basic concepts related to clinical trials, time to absorb materials and assessment of understanding may be necessary in future biomedical prevention trials. (shrink)

Normal science involves persistent collective application of an agreed research agenda. Anomaly can threaten normal science, but so too can “undue persistence” in that agenda by a normal science peer group. We consider how “undue persistence” might be a collective effect of the common incentive structure that individual members of the peer group typically face in relation to their careers. To understand how “undue persistence” might be ameliorated, we consider the affordances of a peer’s membership of a departmental collegium, (...) organized on a different basis than the specialist peer group and hence able to supply the individual scholar with kinds of information and critical comment that may occasion off-agenda contributions to the specialty. The idea of brokerage is borrowed from the sociology of innovation to see how a scholar’s departmental colleagues might be able to broker new ways of thinking that can assist in the avoidance of “undue persistence”.

I want to consider how the general characteristics of a discipline might facilitate ?social mechanisms for distributing knowledge? that do not depend on uniformity of use, but, in fact, on different uses by different people. Indeed, I want to show that the ways in which a discipline is organized afford the growth of knowledge and do so, in particular, by facilitating an approach to what Thomas Kuhn described as ?the essential tension? between, on the one hand, the traditional (...) or customary elements of disciplined enquiry, which are prerequisites for there being a community of enquiry, and, on the other hand, the innovative elements of disciplined enquiry, which are needed on account of the always already inadequate character of our engagement with the objects of enquiry.
