The aim of this paper is to argue that action-guiding vision is not cognitively impenetrable and arguments that suggest otherwise rely on an unjustified identification between actionguiding vision and dorsal vision – a functional and an anatomical way of describing the mind. The examination of these arguments show the importance of making a distinction between the functional and the anatomical level when addressing the problem of cognitive penetrability.

Is action-guiding vision cognitively penetrable? More specifically, is the visual processing that guides our goal-directed actions sensitive to semantic information from cognitive states? This paper critically examines a recent family of arguments whose aim is to challenge a widespread and influential view in philosophy and cognitive science: the view that action-guiding vision is cognitively impenetrable. I argue, in response, that while there may very well be top–down causal influences on action-guiding vision, (...) they should not be taken to be an instance of cognitive penetration. Assuming otherwise is to assign a computational role to the influencing states that they cannot perform. Although questions about cognitive penetrability are ultimately empirical, the issues addressed in this paper are largely philosophical. The discussion here highlights an important set of considerations that help better understand the relations between cognition, vision, and action. (shrink)

According to Milner and Goodale’s dual visual systems (DVS) theory, a division obtains between visual consciousness and motor action, in that the visual system producing conscious vision (the ventral stream) is distinct from the one guiding action (the dorsal stream). That there would be this division is often taken (by Andy Clark and others) to undermine the folk view on how consciousness and action relate. However, even if this division obtains, this leaves open the possibility (...) that con- scious ventral information is often transmitted to the uncon- scious dorsal stream and then used to guide action, a possibility seeming to preserve a significant role for consciousness in action. This article assesses this possibility. In course of doing so, we will review those arguments recently having been made against the DVS view on how visual consciousness and action relate (ones due to, e.g., Briscoe and Schwenkler, or Schenk and McIntosh). What we will find is that, if we properly analyze the data upon which these arguments are based, we are still left with the impression that the DVS view is largely correct; i.e., it is only rarely that visual experience guides action.

David Milner and Melvyn Goodale’s dissociation hypothesis is commonly taken to state that there are two functionally specialized cortical streams of visual processing originating in striate (V1) cortex: a dorsal, action-related “unconscious” stream and a ventral, perception-related “conscious” stream. As Milner and Goodale acknowledge, findings from blindsight studies suggest a more sophisticated picture that replaces the distinction between unconscious vision for action and conscious vision for perception with a tripartite division between unconscious vision for (...) class='Hi'>action, conscious vision for perception, and unconscious vision for perception. The combination excluded by the tripartite division is the possibility of conscious vision for action. But are there good grounds for concluding that there is no conscious vision for action? There is now overwhelming evidence that illusions and perceived size can have a significant effect on action (Bruno & Franz, 2009; Dassonville & Bala, 2004; Franz & Gegenfurtner, 2008; McIntosh & Lashley, 2008). There is also suggestive evidence that any sophisticated visual behavior requires collaboration between the two visual streams at every stage of the process (Schenk & McIntosh, 2010). I nonetheless want to make a case for the tripartite division between unconscious vision for action, conscious vision for perception, and unconscious vision for perception. My aim here is not to refute the evidence showing that conscious vision can affect action but rather to argue (a) that we cannot gain cognitive access to action-guiding dorsal stream representations, and (b) that these representations do not correlate with phenomenal consciousness. This vindicates the semi-conservative view that the dissociation hypothesis is best understood as a tripartite division. (shrink)

It is natural to assume that the fine-grained and highly accurate spatial information present in visual experience is often used to guide our bodily actions. Yet this assumption has been challenged by proponents of the Two Visual Systems Hypothesis , according to which visuomotor programming is the responsibility of a “zombie” processing stream whose sources of bottom-up spatial information are entirely non-conscious . In many formulations of TVSH, the role of conscious vision in action is limited to “recognizing (...) objects, selecting targets for action, and determining what kinds of action, broadly speaking, to perform” . Our aim in this study is to show that the available evidence not only fails to support this dichotomous view but actually reveals a significant role for conscious vision in motor programming, especially for actions that require deliberate attention.

For almost half a century dual-stream advocates have vigorously defended the view that there are two functionally specialized cortical streams of visual processing originating in the primary visual cortex: a ventral, perception-related ‘conscious’ stream and a dorsal, action-related ‘unconscious’ stream. They furthermore maintain that the perceptual and memory systems in the ventral stream are relatively shielded from the action system in the dorsal stream. In recent years, this view has come under scrutiny. Evidence points to two overlapping (...) class='Hi'>action pathways: a dorso-dorsal pathway that calculates features of the object to be acted on, and a ventro-dorsal pathway that transmits stored information about skilled object use from the ventral stream to the dorso-dorsal pathway. This evidence suggests that stored information may exert significantly more influence on visually guided action than hitherto assumed. I argue that this, in turn, supports the notion of skilled automatic action that is nonetheless agential. My focus here will be on actions influenced by implicit biases (stereotypes/prejudices). Action that is biased in this way, I argue, is in an important sense intentional and agential. (shrink)

A broad, though not unanimous, consensus among commentators is that the later Wittgenstein subscribes to a redundancy conception of truth. I reject that interpretation. No doubt much depends on what is meant by a redundancy theory. But once even mildly plausible versions of that view are isolated a review of the relevant texts shows that the evidence for that interpretation collapses. Moreover, the redundancy interpretation is at odds with guiding prescriptions in the post‐1932 corpus. Wittgenstein doesn’t hold that truth (...) can be defined or characterized thinly, as redundancy theorists propose, but that it isn’t susceptible to any such generic treatment. (shrink)

Pakṣilasvāmin Vātsyāyana (c. 450 CE) is the author of the Commentary on Nyāya (Nyāya-bhāṣya), the first full commentary on the Nyāya-sūtra of Gautama (c. 150 CE), which is itself the foundational text of the school of philosophy called “Nyāya.” The Nyāya tradition is home to a number of leading voices within the classical Indian philosophical scene and is celebrated in later doxographies as one of the six “orthodox” systems of Hindu thought. Given the way that sūtra texts and their first (...) commentaries are profoundly intertwined, Vātsyāyana’s work provides a formative vision of Nyāya’s self-conception as a philosophical system as well as interpretive strategies, central lines of argumentation, and determinations of importance that later Naiyāyikas (Nyāya philosophers) often take to be as much as a given as the original text itself. Along with its sustained defense of metaphysical realism across various fronts, Nyāya is best known for its achievements in epistemology and logic, and as indicated by the title of this chapter, the lens through which we will explore Vātsyāyana’s thought is his theory of knowledge. We will give special attention to his account of the nature and importance of cognition as a guide to action and will illustrate the way in which this theme informs a number of apparently distinct elements of his project including his realism, his account of epistemic entitlement, and his notion of philosophy’s contribution to living well.

This paper defends a dynamic model of the way in which perception is integrated with action, a model I refer to as ‘the navigational account’. According to this account, employing vision and other forms of distance perception, a creature acquires information about its surroundings via the senses, information that enables it to select and navigate routes through its environment, so as to attain objects that satisfy its needs. This form of perceptually guided activity should be distinguished from other (...) kinds of semi-automatic responses to visual stimuli that do not necessarily involve conscious experiences. It essentially involves inner states, which involve both the awareness of phenomenal qualities, and also a representational component. The navigational account is compared here with the enactive approach to perception, which opposes the view that perceptual experiences are inner states. This paper argues that a full account of perception raises a number of different questions. One central explanatory project concerns questions about the kinds of processes that currently enable a creature to identify and respond appropriately to distant objects: the answer, it is argued, lies in acknowledging the role of conscious inner representations in guiding navigational behaviour through complex environments. The fact that perception and action are interdependent does not conflict with the claim that inner representational states comprise an essential stage in visual processing. (shrink)

Choking under pressure describes the phenomenon of people performing well below their expected standard under circumstances where optimal performance is crucial. One of the prevailing explanations for choking is that pressure increases the conscious attention to the underlying processes of the performer's task execution, thereby disrupting what would normally be a relatively automatic process. However, research on choking has focused mainly on the influence of pressure on motor performance, typically overlooking how it might alter the way that vision is (...) controlled when performing these motor actions. In this article we ask whether the visual component of expert motor-skill execution is susceptible to choking much like the motor component is thought to be. To do so, we draw heavily on empirical findings from studies of sporting expertise, in particular focussing on the role of gaze in three types of visually-guided actions: interceptive actions, aiming tasks, and anticipatory skill. For each of these skills we evaluate the nature of the expert advantage, discuss the role of consciousness in their control, examine the potential impact of pressure on task performance, and consider interventions designed to reduce the likelihood of choking when performing these tasks.

In _Action in Perception _Alva No develops and presents a sensorimotor account of vision and of visual consciousness. According to such an account seeing (and indeed perceiving more generally) is analysed as a kind of skilful bodily activity. Such a view is consistent with the emerging emphasis, in both philosophy and cognitive science, on the critical role of embodiment in the construction of intelligent agency. I shall argue, however, that the full sensorimotor model faces three important challenges. The first (...) is to negotiate a path between two prima facie unsatisfactory readings of the central claim that conscious perceptual experience is constituted by knowledge of patterns of sensorimotor dependence. The second is to convince us that the sensorimotor contribution, in such cases, is actually constitutive of perceptual experience rather than merely causally implicated in the origination of such experience.² And the third is to respond to the important challenge raised by what I will dub 'sensorimotor summarizing' models of the relation between conscious experience and richly detailed sensorimotor routines. According to such models³ conscious perceptual experience only rather indirectly reflects the rich detail of our actual sensorimotor engagements, which are instead lightly sampled as a coarse guide, optimized for planning and reasoning, and geared and filtered according to current needs and purposes.

Since we explain behavior by ascribing intentional states to the agent, many philosophers have assumed that some guiding principle of folk psychology like [Intentional States and Actions] must be true. [Intentional States and Actions]: If A and B are different actions, then the agents performing them must differ in their intentional states at the time they are performed. Recent results in the physiology of vision present a prima facie problem for this principle. These results show that some visual (...) information that guides spatial manipulation and fine motor control is unavailable for verbal report. Plausibly, this information is not consciously available to the agent, and as such, not available to inform the content of intentional states. Thus, it is hard to see how every difference in action is subject to intentional explanation, as [Intentional States and Actions] requires. I articulate the prima facie problem and argue that the most plausible solution requires us to reject [Intentional States and Actions]. (shrink)

Modern society has undergone a fundamental change to a society built around purposively established organizations. Social theory in this context can be a guide to social construction. Foundations of Social Theory is dedicated to this aim. Being oriented towards the design of social institutions it has to choose a voluntaristic, purposive theory of action and must make the behavior of social systems explainable in terms of the combination of individual actions. It has to deal with the emergence and maintenance (...) of norms and rights, the concepts of authority, trust, law and legitimacy, the viability of organizations and the efficiency of social systems. But more important than the specific points is the vision of a new role for social theory in an increasingly constructed social environment. This vision is the motivation behind Foundations of Social Theory. (shrink)

The present proposal is an approach to the vision, cosmogony and philosophy of the Totonacapan people, and particularly with the inhabitants of the Totonacapan region in Veracruz Mexico, a town whose wisdom is manifested to this day, in the conservation of customs and traditions , as well as the hierarchy of collective desire that seeks health, well-being and peace in the region, are guides in the evolution of their cultural processes, where a closeness, respectful and deep with Mother Nature (...) stands out. This wisdom by the Council of Elders, transmitted to the new generations, by the Supreme Council of Totonacapan who seek share the basis to understand and conceive the current world, from the ancestral vision and cosmogony to identify their space, thought, spirituality and in the building your social context. In the Totonacapan region, the first pre-hispanic population concentrations were located around 1259 to 1311. Already by the year 1450, there is a record of incursions and the conquest of Totonaca territory, by the Mexica, establishing a relationship of domain and subordination. As a result of the presence of "Mexica" in the Totonaco territory, there was an imposition of customs and language, since in some areas they begin to speak in Nahuatl, resulting in the presence of a bilingualism (Nahuatl-Totonac) , situation that persists, until the encounter with the Spaniards in the year of 1519. At present, the Totonacapan region includes the area that extends from the Cazones River to the north, to the towns of Gutiérrez Zamora and Tecolutla, in the State of Veracruz in Mexico. 2 The importance of the document is that it constitutes an invitation to deepen and understand the vision of the inhabitants of Totonacapan, in the construction of their social context and their connection with nature, as part of an ancient culture, which creates and recreates their vision, in the search for the feeling of belonging and as an inheritance of the children of thunder (Tajin), as well as the need to preserve the benefits that nature itself offers them, seeking a peaceful and harmonious coexistence, in the social and environmental environment. However, the preservation of its history, tradition and philosophy of life, contrast with public policy strategies, particularly in the social sphere, and which are aimed at achieving economic development in the fight against multidimensional poverty and marginalization, all Once they have not incorporated into them, the feeling and living of the relationship between individual and nature, as the guiding axis, of the philosophy of the Totonacapan people. What is sustainability for the people of Totonacapan? What is social justice in the search for sustainability? And what is your concept of justice in sustainability and human development? From the vision and philosophy of the people of Totonacapan, as part of the history and tradition of the children of thunder "Tajin" and in whose worldview, he is responsible for regulating the rain, climate and life of the people of the region. How does the people of Totonacapan live and live in the face of the maelstrom of actions that, from public policy, that seek human development? How do you adjust, your way of life and how do you adapt to the requirements, which from the perspective of justice, are required to contribute to the objectives of the 2030 development agenda? This document is an effort to learn and recognize one of the most important millenary cultures in Mexico, in the construction of a more inclusive vision of the social development of the Totonacapan people, which invites us to reflect on the direction and scope of this response.

Philosophical personalism has generated a very powerful field of study in the twentieth and twenty first centuries but has not produced a systematic exposition. This book fills this big gap by offering for the first time a full systematic personalistic vision of the human person. This ambitious volume offers a pedagogical and integrated exposition of philosophical personalism, answering vital questions about human identity and existence in a way that the reader can achieve an integrated view of the person. The (...) book points to the real life of each person so that, by partially unraveling the mystery of the personal being, it becomes a philosophical guide for life. For these reasons, the book can be used both for academic purposes, as a manual of philosophy of man or for personal enlightenment. Divided in five parts, the first part of the book works as an introduction, offering an overview of the human person and of the notion of person. The second part describes the internal structure of the human being addressing topics as corporeity as a personal fact; sensibility and the senses; affectivity; intelligence; freedom understood as choice and self-determination and, finally, the personal self. The third part analyses the person in action and some special types of action such as work and language. The fourth part deals with interpersonal relationships beginning with I-You relationship and following with the family and the social structure. Finally, part five deals with the so-called ultimate questions, that is, those that decide the final meaning of each person's life, namely, time, death, immortality, and religion. (shrink)

This paper presents a general computational treatment of how mammals are able to deal with visual objects and environments. The model tries to cover the entire range from behavior and phenomenological experience to detailed neural encodings in crude but computationally plausible reductive steps. The problems addressed include perceptual constancies, eye movements and the stable visual world, object descriptions, perceptual generalizations, and the representation of extrapersonal space.The entire development is based on an action-oriented notion of perception. The observer is assumed (...) to be continuously sampling the ambient light for information of current value. The central problem of vision is taken to be categorizing and locating objects in the environment. The critical step in this process is the linking of visual information to symbolic object descriptions; this is calledindexing, from the analogy of identifying a book from index terms. The system must also identifysituationsand use this knowledge to guide movement and other actions in the environment. The treatment focuses on the different representations of information used in the visual system.The four representational frames capture information in the following forms: retinotopic, head-based, symbolic, and allocentric. The functional roles of the four frames, the communication among them, and their suggested neurophysiological realization constitute the core of the paper. The model is perforce crude, but appears to be consistent with all relevant findings. (shrink)

Two major functions of the visual system are discussed and contrasted. One function of vision is the creation of an internal model or percept of the external world. Most research in object perception has concentrated on this aspect of vision. Vision also guides the control of object-directed action. In the latter case, vision directs our actions with respect to the world by transforming visual inputs into appropriate motor outputs. We argue that separate, but interactive, visual (...) systems have evolved for the perception of objects on the one hand and the control of actions directed at those objects on the other. This 'duplex' approach to high-level vision suggests that Marrian or 'reconstructive' approaches and Gibsonian or 'purposive-animate-behaviorist' approaches need not be seen as mutually exclusive, but rather as complementary in their emphases on different aspects of visual function.

L'examen de la politique audiovisuelle extérieure de la France en matière de télévision, de 1984 à aujourd'hui, permet de constater que celle-ci a été relativement stable, notamment à travers le développement de la chaîne TV5. Après avoir souligné que la création de cette chaîne s'inscrit dans une vision très culturelle de la diffusion audiovisuelle, nous montrons qu'elle entretient des rapports ambigus avec la question francophone en matière de public, de programmes et de langue. Le cas de l'information, ensuite envisagé, (...) est d'autant plus intéressant que le gouvernement développe à l'heure actuelle un projet qui relève plus d'une stratégie politique que de la logique culturelle et francophone qui sous-tendait TV5.It can be noted that, since 1984, French audiovisual foreign policy has remained quite steady particularly regarding the development of the TV5 channel. We consider this channel particularly representative of a largely cultural vision of audiovisual broadcasting. We also show that TV5 has an ambiguous attitude to the francophone issue in terms of audience, TV schedules and the language itself. It also seems that in the field of news broadcasting, the French government is more interested in political strategy than in the cultural and francophone guiding principles that used to be TV5's mission.

Depuis 2012, nous disposons enfin en français d'une traduction satisfaisante des livres publiés par Hannah Arendt aux Etats-Unis de 1951 à 1972. Il est ainsi possible à tout citoyen francophone curieux de cette pensée d'accéder directement à l'une des oeuvres politiques les plus originales du XXe siècle. Pensée toujours vivante et qui, dans un moment de changement d'époque, peut nous aider non à trouver les solutions, mais, ce qui est plus essentiel, à nous poser des questions pertinentes. Les commentaires sur (...) l'oeuvre d'Arendt se sont tellement multipliés depuis trente ans que le travail critique a peut-être fini par empêcher l'accès direct à sa pensée. Cet ouvrage poursuit donc un objectif : fournir un guide de voyage à travers l'oeuvre politique d'Arendt. La première partie est consacrée à la genèse, comme penseur politique, de Hannah Arendt depuis sa naissance en Allemagne en 1906 jusqu'à la publication aux Etats-Unis des Origines du totalitarisme en 1951. La deuxième partie constitue le coeur du livre. Le premier chapitre propose une vision d'ensemble des oeuvres en naviguant d'un ouvrage à l'autre et en saisissant le développement d'une pensée s'élaborant à partir des événements. Les sept chapitres suivants permettent au lecteur de s'orienter dans chacun des sept livres. Le dernier chapitre propose un glossaire, le lecteur voyageant, à nouveau, à travers les sept livres avec, pour fil directeur, un choix des notions et distinctions qu'ils abordent. La troisième et dernière partie ouvre une réflexion sous forme de questionnement. En quoi la matière apportée par l'oeuvre de Hannah Arendt peut-elle nous aider à penser nos choix et nos actions?

The central problem of the ‘normativity of law’ concerns how legal rules or directives give us reasons for actions. The core of this question is how something that is external to the agent, such as legal rules or directives, can be ‘part of the agent’, and how they can guide the agent in performing complex actions (such as legal rule-following) that persist over time. David Enoch has denied that the normativity of law poses any interesting challenge to theories of law. (...) He argues that law provides reasons for actions in terms of what he calls triggering-reasons and he advances the view that because there are many circumstances in which reasons are triggered, law does not pose a special challenge. According to Enoch, once we understand the way that triggering reasons operate, we can understand how legal rules and directives provide us with reasons for actions. In §II of this paper, I set the stage for the debate and establish a set of principles that emerge from the common sense of view of reasons for actions and argue that any theory of reasons for action should provide a coherent explanation of these key principles. I focus on the idea that a satisfactory account of reasons for action should also explain reasons in actions. In §III I explain briefly the different theories of reasons for action and locate Enoch’s conception of reasons for action as triggering-reasons within this theoretical framework. In §IV I show that Enoch’s conception of reasons for actions does not explain some of the key features or principles that emerge from our common sense view of reasons for action and nor does it explain reasons in actions.Resumen:El problema central de la ‘normatividad del derecho’ versa sobre cómo las reglas o directrices jurídicas nos dan razones para la acción. El núcleo de esta cuestión reside en cómo algo que es externo al agente, tal como las reglas o directrices jurídicas, pueden ser ‘parte del agente’, y cómo pueden guiar a ese agente al llevar a cabo acciones complejas (tal como la obediencia de las reglas) que persisten en el tiempo. David Enoch ha negado que la normatividad del derecho presente algún reto interesante a las teorías del derecho. Arguye que el derecho provee razones para la acción en términos de lo que él llama razones detonantes (triggering-reasons) y propone la perspectiva de que, dado que hay muchas circunstancias bajo las cuales se detonan las razones, el derecho no plantea ningún reto especial. De acuerdo con Enoch, una vez que entendemos la manera en que operan las razones detonantes, podemos comprender cómo las reglas y directrices jurídicas nos proveen razones para la acción. En la sección II de este artículo, fijo el escenario para el debate y establezco una serie de principios que emergen de la visión de sentido común sobre las razones para las acciones, y sostengo que cual- quier teoría de las razones para la acción debería proporcionar una explicación coherente de estos principios clave. Me centro en la idea de que una concepción satisfactoria de las razones para la acción también debe- ría explicar las razones en las acciones. En la sección III, explico brevemente las diferentes teorías de las razones para la acción y ubico la concepción de Enoch de razones para la acción como razones detonantes (triggering-reasons) dentro de este marco teórico. En la sección IV muestro que la concepción de Enoch de razones para las acciones no explica algunas de las principales características o principios que emergen de nuestra visión de las razones para la acción basada en el sentido común, ni tampoco explica las razones en las acciones.

Vision substitution by electro-stimulation has been studied since the 60s beginning with P. Bach-y-Rita. Camera pictures or movies encoded in gray levels are displayed using an electro-stimulation display device on the surface of a body part, such as the skin or the tongue. Medical-technical devices have been developed on this principle to compensate for sensory-motor disabilities such as blindness or loss of balance, or to guide specific actions, such as surgery. However, the electrical signals of stationary or moving slowly (...) moving objects, displayed on a Tongue display unit , are quickly lost due to saturation of receptors undergoing electrostimulation. We propose to add random saccades or sparkle to the displayed visual scene to increase the quality of pattern recognition by the subjects. In the present experimental trimodal study , we show that the presence of a moderate sparkle level enhances the perception of the direction of lines drawn on a TDU and reduces the response time.

What representational state mediates between perception and action? Bence Nanay says pragmatic representations, which are outputs of perceptual systems. This commits him to the view that optic ataxics face difficulty in performing visually guided arm movements because the relevant perceptual systems output their pragmatic representations incorrectly. Here, I argue that it is not enough to say that pragmatic representations are output incorrectly; we also need to know why they are output that way. Given recent evidence that optic ataxia impairs (...) peripersonal space representation, I argue that pragmatic representations are output incorrectly because the organizing principle of the vision-for-action system is blocked by optic ataxia. I then show how this means that this principle, not pragmatic representations, is the representational state that mediates between perception and action, i.e. the principle, not pragmatic representations, is the immediate mental antecedent of action.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Holocaust Visions: Surrealism and Existentialism in the Poetry of Paul CelanVéronique M. FótiHolocaust Visions: Surrealism and Existentialism in the Poetry of Paul Celan, by Clarise Samuels; x & 134 pp. Columbia, South Carolina: Camden House, 1993, $53.50.Samuels’s thesis is that Celan’s poetic work in its entirety can and should be understood as a comprehensive and unified philosophical system, in which each poem is assigned its place. This system (...) is not outlined in terms of its organizing principles, but rather in its topography of three superimposed layers. The top layer (which an empiricist would consider foundational) mirrors an “objective” reality and is informed by finehoned observation, whereas the middle layer constitutes an “ideological program” that “attempts to establish a socio-political value system” (p. 2), while the supporting bottom layer offers an “existentialist epistemology.”Despite her stress on systematicity (obsolete since Hegel), Samuels identifies surrealism (particularly the strand deriving from Breton) and existentialism as the formative influences on Celan’s poetics; and she carefully explores the interrelations of these movements of thought with the heritage of French symbolism, and with Dadaism and Marxism. She does not, however, use guiding concepts, such as “epistemology” or “ideology,” in any precise philosophical sense. By “epistemology” she seems to mean a fundamental concern for reality and truth, coupled with the belief that truth is accessible beyond [End Page 382] social constructions of meaning, whereas “ideology” is used in the various senses of revolutionary program, utopian vision, structure of ideas, or even just ideation (as in “On the ideological level, the Holocaust fulfills the surrealist intention of entering the individual’s subconscious,” p. 108).On the basis of her analyses of surrealist and existentialist thought, Samuels examines Celan’s poetry and poetics with a view to his search for an “alter reality” that would transcend, but not negate, the “Holocaust universe.” She first researches Celan’s syntactic structures, such as the “genitive phrase,” the elliptical sentence, or the fragmentation (and recombination) of words, to move on to a discussion of his tropes, which she arranges broadly into “representations of space, time, persons, and actions” (p. 39). Her discussion of Celan’s spatial tropes, particularly of his devastated imaginary landscapes and places of loss (unfortunately “space” and “place” are not distinguished), is especially compelling. It is further enriched, in the final chapter, which seeks to elucidate Celan’s notion of utopia and to locate utopia in art, by reference to the visual work of Tanguy, Ernst, and Magritte.The book as a whole is meticulously researched and includes extensive discussions of the secondary literature, with a slant toward Germanistik rather than philosophy, and with perhaps a particular debt to Marlies Janz. Its weakness is, in a way, tied to its strength: in her discussions of philosophical concepts and movements, Samuels seems to rely largely on (somewhat dated) secondary literature, so that her philosophical understanding is frequently a confused amalgam. For instance, she links Sartre’s in-itself to the Kantian noumenon (p. 20) and goes on to locate it, not only in the “universe,” but also “at the core of the human self,” so that the for-itself contrasts with it as a “superficial” construction, a sort of artifact that needs to be “controlled.” She assimilates the nihilating character of Sartrean consciousness to a “principle of nihilism” that supposedly characterizes existentialism, while nevertheless interpreting Sartre’s humanism as a turn toward “the eternal aspect” of mankind. Heidegger is cast as an existentialist in search of a literalized authenticity, while his critique of Sartrean humanism is simply ignored.In treating Celan’s poetry as systematically coherent and as, in some sense, ideological, Samuels not only disregards the striking stylistic changes that characterize its various phases, but she also does not try to unravel its intricate textual fabric of allusions (notably to Hölderlin and Trakl), to analyze textual structures such as the displaced re-inscription of the date (notably Büchner’s Jänner), or to respond to its unleashing of the semantic energies that lie latent beneath the surface of ordinary language. Sometimes she overlooks her own inchoate interpretive insights, as in her two discussions of parts of... (shrink)

Comprehensively improving the level of vocational education and teaching quality has become an important initiative to meet the new round of technological revolution and industrial change. The traditional teaching mode can no longer meet the needs of industries and enterprises for job competences, and all higher education institutions are actively thinking about how to carry out teaching reform. Virtual reality can effectively solve the above-mentioned drawbacks, but the hardware facilities of the existing VR systems are extremely expensive, making it impossible (...) to popularize it in teaching. In this context, this paper is based on VR for the design of an interactive teaching platform. This paper discusses the key technologies of virtual reality, introduces the relevant theoretical foundation, and describes the current virtual reality devices with high popularity and their advantages and disadvantages for systematic analysis. From the perspective of teaching design, the design of human-computer interaction teaching process using VR technology to develop learning scenes is studied, introducing 3D modeling techniques, model construction, the production of picture and text panels, the production of video materials, and the establishment of virtual tour guide 3D scenes. The principle of this paper is to build a 3D vision for building 3D views of educational needs to design high quality images and video animation using 3DMAX and unity 3D engines. Then, we introduce the use of VR glasses, smart phones, and Bluetooth wireless handle to build a simple interactive teaching platform; the platform is of low cost of construction and student coverage, to solve the teaching resources shortage, equipment conditions lagging behind, the curriculum content aging, teachers and students who cannot interact in real time, and a series of problems.

This article proposes an action guide to making decisions regarding the ethical allocation of resources that affect access to healthcare services offered by community-based healthcare organizations. Using the filter of empirical data from a study of decision making in two community-based healthcare organizations, we identify potentially relevant conceptual guidance from a review of frameworks and action guides in the public health, health policy, and organizational ethics literature. We describe the development of this action guide. We used data (...) from a prior empirical study of the values that influence decision making about the allocation of resources in particular types of community-based healthcare organizations. We evaluated, organized, and specified the conceptual guidance we found in 14 frameworks for ethical decision making. The result is an action guide that includes four domains that are relevant to the context of the decision to be made, eight domains that are relevant to the process of the decision to be made, and 15 domains that are relevant to the criteria of the decision to be made. We demonstrate the potential use of this action guide by walking through an illustrative resource allocation decision. The action guide provides community-based healthcare organizations with a conceptually grounded, empirically informed framework for ethical decision making. (shrink)

The current discussion of business ethics is nothing new. In fact it has been a topic of common interest to both researchers and top managers since the mid fifties; the focus adjusting to issues and problems of the times. The authors of the article list four themes they believe to be of relevance for future discussion. First, ethics as an instrument of business behavior is entering a new dimension due to negative side effects of economic activities, which are even observed (...) on a global scale and where it is doubtful that governments can adequately manage this complex environment. From this view, ethics becomes a decisive component of efficiency and requires a new way of thinking on the development of the market system and on a new delineation of responsibilities between government and markets. Second, in the process of transformation of the East-European states it seems to be all the more important to emphasize the ethical characteristics which are part of the concept of competition — the gains to the consumer due to the plurality of search and discovery procedures, the capability to correct and absorb wrong decisions, and the specific distributional ethics. Third, business ethics as an element of the firm''s guiding vision has to be incorporated into its corporate culture, which will foster an institutional ethic of the firm — the joint effect of individual ethics within the history of the firm coupled with time and experience. Fourth, conflicting business philosophies must be judged with reference to the process of communication of business ethics. Summing up business ethics has a micro and macro component and is related to the individual firm as well as to the structure of the economic and social order. Ethics will, however, have a limited effect if it is not accompanied by the change in goals, structures and processes. (shrink)

Various political realists claim the superior ‘action-guiding’ qualities of their way of approaching normative political theory, as compared to ‘liberal moralism’. This paper subjects that claim to critique. I first clarify the general idea of action-guidance, and identify two types of guidance that a political theory might try to offer – ‘prescriptive action-guidance’ and ‘orienting action-guidance’ – together with the conditions that must be met before we can understand such guidance as having been successfully offered. (...) I then go on to argue that if we take realist understandings of political psychology seriously, then realist attempts to offer action-guidance appear to fail by realism’s own lights. I demonstrate this by means of engagement with a variety of different realist theorists. (shrink)

What are the main conditions that any theory of human rights should satisfy to guide action? If agents must take action for a fairer world as human rights discourse suggests, this is a crucial question to reflect upon. In this paper, I make a proposal. I argue that any theory of (moral) human rights that guides action on the basis of correlative duties must satisfy three key conditions. The first condition is focused on the specification of act-types, (...) the second concerns the distribution of correlative duties, and the third is focused on the resolution of (resolvable) conflicts of human rights. I show that this proposal has substantive implications because it implies to reject, challenge and, in some cases, resist ideas that are commonly accepted in the literature on human rights. (shrink)

What’s presented in our normal waking perceptual visual experiences feels present to us, while what we “see” in pictures and imagine does not. What about dreams? Does what we “see” in a dream feel present? Jennifer Windt has argued for an affirmative answer, for all dreams. But the dreams which flow from the brain’s registration of myoclonic twitches present a challenge to this answer. During these dreams motion-guiding vision is shut off, and, as Mohan Matthen has argued, motion- (...) class='Hi'>guiding vision seems to be a key mechanism underlying the feeling of presence. I propose that the feeling of presence in fact involves two components: the feeling of immersion, and the feeling of availability for action. I suggest that only the feeling of availability for action derives from motion-guiding vision, and, hence, hypothesize that body-driven dreams lack this component to the feeling of presence. Finally, the distinction between these two varieties of presence has implications for measures of presence in virtual environments, as these measures can diverge over which of the two varieties they track.

In his book, Contemporary Theories of Knowledge, John Pollock argues that all externalist theories of justification should be rejected on the grounds that they do not do justice to the action-guiding character of epistemic norms. I reply that Pollocks argument is ineffective — because not all externalisms are intended to involve action-guiding norms, and because Pollock does not give a good reason for thinking that action-guiding norms must be internalist norms. Second, I consider rehabilitating (...) Pollocks argument by restricting his conclusion to theories that do involve action-guiding norms and providing a better reason to think that action-guiding norms must be internalist norms. But I claim that if Pollocks argument is made strong enough to rule out all externalisms, it rules out too much, namely, any plausible conception of epistemic norms. (shrink)

Is it justified to hold that an agent S has a (moral) right to P if the duty-bearer is not specified? There is an intense ongoing debate on this question. There are two positions in the literature. On the one hand, O´Neill´s much-discussed account of rights holds that it is justified to say that an agent S has a right to P if and only if the duty-bearer is sufficiently determined – i.e. if and only if it is clear against (...) whom S may claim her right to P (O’Neill 1986, 1988, 1996, 2000, 2005, 2016). Call this, the ‘claimability condition’. On the other hand, interest-based theorists argue that it can be justified to say that an agent S has a right to P even if the duty-bearer is not sufficiently determined (Caney 2007; Griffin, 2008; Raz 1988; Tasioulas 2007; see also: Etinson, 2013; Ypi 2010). Who (if anyone) is correct in this fundamental discussion about the very nature of rights? In this paper, I provide an answer to this crucial question. Neither O´Neill nor interest-based theorists provide good reasons to justify their positions. However, I argue, the claimability condition is an existence condition of rights justified on the basis of their action-guiding character. The reason is that if the duty-bearer is not specified, the content of the right (its correlative obligation) does not sufficiently guide what the agent should do because it is indeterminate who is required to act (or refrain from acting).

The early Stoics diagnose vicious agents with various psychological diseases, e.g. love of money and love of wine. Such diseases are characterized as false evaluative opinions that lead the agent to form emotional impulses for certain objects, e.g. money and wine. Scholars have therefore analyzed psychological diseases simply as dispositions for assent. This interpretation is incomplete, I argue, and should be augmented with the claim that psychological disease also affects what kind of action-guiding impressions are created prior to (...) giving assent. This proposal respects the Stoic insistence that impression-formation, no less than assent, is an activity of reason. In so far as the wine-lover’s reason is corrupted in a different way from the money-lover’s, the two vicious agents will form different action-guiding impressions when faced with similar stimuli. Here I juxtapose the Stoic account of expertise, according to which experts form more precise action-guiding impressions compared to the amateur, in virtue of possessing a system of grasps (katalēpseis). So expertise enhances, whereas psychological disease degrades, the representational fidelity of the impressions that prefigure action. With these commitments, the Stoics can be seen to offer a nuanced and principled theory of cognitive penetration and to anticipate some recent proposals in epistemology and cognitive science.

I defend moral objectivism against charges that it cannot plausibly preserve or explain morality's action-guiding nature. I take as my starting point the intuitive view that morality has a special connection to motivation: one who genuinely accepts a moral verdict must have a motivating reason to follow its dictates and, indeed, must often enough be motivated to act as it recommends. ;Many have argued that this connection vindicates subjectivism. Some argue that there can be no universally accessible truths (...) whose acknowledgements necessarily give one reason to act, because all reasons for action are based on desires that vary across rational agents. I argue against the Humean doctrine, implicit in this claim, that beliefs alone cannot move rational agents. The 18th-century metaphors of "passive" belief and "active" desire rest on arguments which either beg the question, equivocate, or misunderstand what would be involved in attributing the appropriate motivational power to belief. Others ground their objection in morality's holistic tie to desire, claiming that desires distort truth, rather than reveal it to us. I argue that there is nothing mysterious about the idea that possession of certain desires can be preconditions to seeing how things are. (shrink)

The main objective of the Flemish research project ‘Nanotechnologies for tomorrow’s society’ (NanoSoc) is to develop and try out an interactive process as a suitable methodology for rendering nanoresearchers aware of underlying assumptions that guide nanotech research and integrating social considerations into the research choices they face. In particular, the NanoSoc process should sustain scientists’ capacities to address growing uncertainties on the strategic, scientific and public acceptance level. The article elaborates on these uncertainties and involved dilemmas scientists are facing and (...) proposes a process approach which addresses strategic uncertainty by alternating between ‘visioning’ and ‘technology assessment’; a process design which manages complexity by promoting reflexivity among scientists by exposing them to deliberations in civil society (social experts, stakeholders, citizens) on plausible futures with nanotechnologies; and as an answer to societal ambivalence, certain process quality requirements such as an attitude of perplexity or openness towards ‘plurality’ and an attitude of ‘temporary closure’, both in support of understanding and learning from differences.

Developing an intellectualist account of skill, Stanley and Williamson define skill as a kind of disposition to action-guiding knowledge. The present paper challenges their definition of skill. While we don’t dispute that skill may consist of a cognitive, a dispositional, and an action-guiding component, we argue that Stanley and Williamson’s account of each component is problematic. In the first section, we argue, against Stanley and Williamson, that the cognitive component of skill is not a case of (...) propositional knowledge-wh, which is typically indexical. In the second section, we seek to show that Stanley and Williamson face difficulties in arguing for a generic claim about skill as a kind of disposition, and they fail to defend intellectualism about skill based on the dispositional account. In the third section we argue that Stanley and Williamson need a more detailed account of the action-guiding aspect of skill to avoid several difficulties, including a threat of a regress. We close with some lessons for the debate over intellectualism and anti-intellectualism about skill. (shrink)

The aim of this paper is to raise some serious worries about anti-representationalism: the recently popular view according to which there are no perceptual representations. Although anti-representationalism is more and more popular, I will argue that we have strong empirical reasons for mistrusting it. More specifically, I will argue that it is inconsistent with some important empirical findings about dorsal perception and about the multimodality of perception.
