Those accustomed to the thoroughness, exactitude, and incisiveness of Alston’s epistemological forays will not be disappointed by this work. Once more, Alston takes a keen-edged scalpel to various central issues such as externalism versus internalism, reliabilism, foundationalism, coherence, truth-conduciveness, epistemic virtue, skepticism, contextualism, and epistemic probability. However, his central thesis is that researchers should replace the notion of “justified belief” with a series of positive distinctively epistemic features of beliefs, called “epistemic desiderata” or “EDs.” He maintains that philosophers have been (...) bamboozled by focusing on the question of when a belief is justified. The field is much more crowded. Although not every petitioner warrants entrance, a number of candidate EDs deserve consideration. (shrink)

The correspondence of a sensory object to the category of a descriptive statement requires a reflexive-identity of the object, and such a reflexive-identity is primarily based on the cognition of spatiality. Spatiality is, however, constituted through visual perception. There are only two occasions on which definitive reflexive-identity is exemplified: the infinitesimal point and the infinite “One,” and others are just human stipulations that meet pragmatic needs of rough identification of things at hand. However, if a spatial point is not different (...) from any so-called “other” spatial point, to validate the reflexive identity of any spatial point implies a validation of the reflexive identity of all spatial points. Thus, as “one” and “many” here become absolutely unitary, the infinitely small and the infinitely immense are identical. (shrink)

Colour fascinates all of us, and scientists and philosophers have sought to understand the true nature of colour vision for many years. In recent times, investigations into colour vision have been one of the main success stories of cognitive science, for each discipline within the field - neuroscience, psychology, linguistics, computer science and artificial intelligence, and philosophy - has contributed significantly to our understanding of colour. Evan Thompson's book is a major contribution to this interdisciplinary project. Colour (...) class='Hi'>Vision provides an accessible review of the current scientific and philosophical discussions of colour vision. Thompson steers a course between the subjective and objective positions on colour, arguing for a relational account. This account develops a novel `ecological' approach to colour vision in cognitive science and the philosophy of perception. It is vital reading for all cognitive scientists and philosophers whose interests touch upon this central area. (shrink)

Colour vision plays a foundational explanatory role in the philosophy of colour, and serves as perennial quarry in the wider philosophy of perception. I present two contributions to our understanding of this notion. The first is to develop a constitutive approach to characterizing colour vision. This approach seeks to comprehend the nature of colour vision qua psychological kind, as contrasted with traditional experiential approaches, which prioritize descriptions of our ordinary visual experience of colour. The second contribution is (...) to argue that colour vision does not constitutively involve the ability to see colours, in a natural and categorically committed sense. I argue that two subjects exactly alike in respect of their constitutive colour vision abilities could differ in respect of whether or not they have categorical perception of colour. The argument is supported by thought experiment and dissociations observed in cognitive neuropsychology. The argument also bears connections to recent neo-Whorfian accounts of colour categorization. _1._ Introduction _2._ Colour Vision, Experience, and Natures _3._ The Central Argument _3.1._ Colour constancy and discrimination _3.2._ Dissociating colour vision and categorical perception for colour _4._ Whorf and the View from Cognitive Neuropsychology _5._ Conclusion.

L'éducation est dans ce livre envisagée comme un geste anthropologique intégral par lequel chaque personne s'achemine vers la plénitude de son être, dans le respect de sa destination naturelle et surnaturelle. À la lumière de cette mystique éducative qui nous fait entrer au coeur de la réalité humaine, l'existence se trouve intensifiée, parce que vécue avec un maximum de profondeur. Encore trop méconnu, l'apport d'Edith Stein en matière d'éducation méritait d'être enfin présenté sous une forme synthétique et accessible. La question (...) éducative occupe une place centrale dans la pensée d'Edith Stein, sans toutefois faire l'objet d'une mise en forme systématique. Cela justifie amplement le projet d'une reconstitution de son architecture d'ensemble. (shrink)

This paper considers an objection to intentionalism (the view that the phenomenal character of experience supervenes on intentional content) based on the phenomenology of blurred vision. Several intentionalists, including Michael Tye, Fred Dretske, and Timothy Crane, have proposed intentionalist explanations of blurred vision phenomenology. I argue that their proposals fail and propose a solution of my own that, I contend, is the only promising explanation consistent with intentionalism. The solution, however, comes at a cost for intentionalists; it involves (...) rejecting the "transparency of experience", a doctrine that has been the basis for the central argument in favor of intentionalism.

Since industrial trade fair Hannover Messe 2011, the term “Industrie 4.0” has ignited a vision of a new Industrial Revolution and has been inspiring a lively, ongoing debate among the German public about the future of work, and hence society, ever since. The discourse around this vision of the future eventually spread to other countries, with public awareness reaching a temporary peak in 2016 when the World Economic Forum’s meeting in Davos was held with the motto “Mastering the (...) Fourth Industrial Revolution.” How is it possible for a vision originally established by three German engineers to unfold and bear fruit at a global level in such a short period of time? This article begins with a summary of the key ideas that are discussed under the label Industrie 4.0. The main purpose, based on an in-depth discourse analysis, is to debunk the myth about the origin of this powerful vision and to trace the narrative back to the global economic crisis in 2009 and thus to the real actors, central discourse patterns, and hidden intentions of this vision of a new Industrial Revolution. In conclusion, the discourse analysis reveals that this is not a case of visioneering but one of a future told, tamed, and traded. (shrink)

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.

As an imaginative vision of life as a whole is a central part of our mental equipment for any serious study, we must be careful what vision we espouse. If science is not furnished with a sensible one, it cannot fail to gather a wild one.

The beatific vision is central to St. Thomas Aquinas’ doctrine of the soul’s enlightenment. In its vision of the essence of God, the soul/intellect achieves its telos, its highest goal. But the resurrection of the body is a central dogma of the Christian faith, so the main question of this essay concerns the manner in which the resurrected body of the blessed benefits from the soul’s apprehension of the beatific vision. For St. Thomas, the physical eyes do (...) not see the beatific vision, since they can only see magnitude and proportion, and God is beyond both. The soul is the body’s substantial form, and a person is not fully a person without the union of soul and body. As the body’s substantial form, the soul/intellect has the beatific vision as its substantial form. The result of the enlightened intellect with the resurrected body will be that the physical eyes will be able to see more readily the glory of God in creation and in redeemed humanity, and more supremely in the incarnate Christ himself.

Technology clearly plays a central role in Black Panther. Black Panther tries to make us think about the benefits and risks of employing vibranium – and by extension any advanced technology – to different ends. Through the blend of traditional cultures and technology, the Black Panther movie works as a powerfully imaginative thought experiment that explores the technological and cultural ramifications of an enlightened technologically advanced Afrofuturistic civilization. Wakanda's depiction as an independent African technological utopia where people live in harmony (...) with nature and among themselves offers a celebration both of the fruits of technology and of traditional African cultures. By imagining what an African techno‐utopia might look like, the movie tries to reimagine the relations between technology and culture. Vibranium has a cultural and spiritual role that is more prominent than its strictly technological properties. (shrink)

Various geoengineering technologies that would deliberately alter the climate system have been proposed as a way to alleviate risks of global warming. Technologies that would shield incoming sunlight to cool the planet, so called solar radiation management, are particularly controversial. Considering insights from social studies of simulation modeling and research on expectations in science and technology, I argue that climate modeling has a central role in producing visions of SRM. I draw upon an empirical analysis of scientific research on SRM (...) to examine how a creative play with technological ideas becomes possible through climate modeling. This enables scientists to project and study environmental impacts of speculative SRM methods in virtual experiments and to develop and refine ideas for adjusting sunlight. Hence, while climate models are used to improve scientific understandings of climate system behavior and to anticipate possible environmental impacts of SRM, they also become inventive tools, allowing scientists to envision novel ways of climate control and optimization. Given the importance of simulation studies to knowledge production on SRM, I critically reflect on the challenges that arise when visions about an engineered climate future are first and foremost produced in climate simulations.

In the conclusion of the last section, we suggested that it is illuminating to compare Sellars' philosophy with that of Kant. This can clearly be seen with reference to his attack on the "myth of the given," his positive analysis of concepts, and his classification of the manifest image as phenomenal. But the analogy with Kant is also helpful in clarifying two further notions that are essential for completing the sketch of Sellars' system: persons and reality. Although Sellars has written (...) a number of papers that delineate and defend the logic of intentions, which is the heart of what is distinctive about persons, one topic that he has not explored in great detail is the "unity of the persons." The category of persons which is the fundamental category of the manifest image and which must be joined with the scientific image if we are to achieve a true synoptic vision of man-in-the-universe presents a central difficulty for Sellars' systematic edifice. For he attempts to show the compatibility of what at first seem to be contradictory claims. On the one hand he maintains that a reconstruction of the category of persons in terms of the fundamental concepts of the scientific image "is in principle impossible, the impossibility in question being a strictly logical one". On the other hand, he claims that persons can in principle be exhaustively described and explained in terms of the scientific image. A person is nothing more than a multiplicity of logical subjects and the precise nature of these subjects can eventually be revealed in the development of scientific inquiry. (shrink)

Is vision informationally encapsulated from cognition or is it cognitively penetrated? I shall argue that intentions penetrate vision in the experience of visual spatial constancy: the world appears to be spatially stable despite our frequent eye movements. I explicate the nature of this experience and critically examine and extend current neurobiological accounts of spatial constancy, emphasizing the central role of motor signals in computing such constancy. I then provide a stringent condition for failure of informational encapsulation that emphasizes (...) a computational condition for cognitive penetration: cognition must serve as an informational resource for visual computation. This requires proposals regarding semantic information transfer, a crucial issue in any model of informational encapsulation. I then argue that intention provides an informational resource for computation of visual spatial constancy. Hence, intention penetrates vision. (shrink)

Recent work on non-visual modalities aims to translate, extend, revise, or unify claims about perception beyond vision. This paper presents central lessons drawn from attention to hearing, sounds, and multimodality. It focuses on auditory awareness and its objects, and it advances more general lessons for perceptual theorizing that emerge from thinking about sounds and audition. The paper argues that sounds and audition no better support the privacy of perception’s objects than does vision; that perceptual objects are more diverse (...) than an exclusively visual perspective suggests; and that multimodality is rampant. In doing so, it presents an account according to which audition affords awareness as of not just sounds, but also environmental happenings beyond sounds. (shrink)

The pinnacle of the Novak’s reflections on possible perspectives for the future of the world and the development of international relations is his vision of “Caritapolis” (“Civilization of love”), which is presented especially in the book The universal hunger for liberty – Why the clash of civilizations is not inevitable (2004a). Novak builds the concept on the religious assumptions and on the minimum level of general belief in basic principles (cultural humility, regulative idea of truth, the dignity of the (...) individual person, solidarity), which he considers to be the key to the world security, prosperity and the democratic future of the globalized world. This “vision for the 21st century” is to contribute to the consideration of a universal civilization that would respect all its internal variations and create a certain unity despite its rich diversity of value and religious ideas. The aim of this paper is to present Novak’s concept of Caritapolis and to evaluate it in terms of context of the social doctrine of the Church, Catholic social thought debates, relevance in the context of debates in the social sciences, especially the theories of international relations.

The idea of a 'property-owning democracy' became central to John Rawls's re-evaluation of his theory of justice. This article traces the origins of Rawls's concept of `property-owning democracy' first to the writings of the economist James Meade and then to those of early twentieth-century British conservatives, focusing on the question of how the meaning of democracy was defined and re-defined throughout this history. I argue that Rawls inherited a discursive matrix from the British conservatives in which the notion of 'property-owning (...) democracy' refers to the limits that should be set on democratic practices to make democracy compatible with the needs and interests of property-owners. In addition to tracing the genealogy of the idea of a 'property-owning democracy', the article points toward more recent attempts, partially inspired by Rawls's 'political turn', to re-examine the distribution of property-ownership from the perspective of what is required for viable democratic deliberations. The article ends with an addendum lamenting the fact that when George W. Bush's administration adopted the British ideas and policies associated with 'property-owning democracy' it chose to omit 'democracy' altogether and to describe its initiative as 'ownership society'.

When the stored representation of the meaning of a stimulus is accessed through the processing of a sensory input it is maintained in an activated state for a certain amount of time that allows for further processing. This semantic activation is generally accompanied by conscious identification, which can be demonstrated by the ability of a person to perform discriminations on the basis of the meaning of the stimulus. The idea that a sensory input can give rise to semantic activation without (...) concomitant conscious identification was the central thesis of the controversial research in subliminal perception. Recently, new claims for the existence of such phenomena have arisen from studies in dichotic listening, parafoveal vision, and visual pattern masking. Because of the fundamental role played by these types of experiments in cognitive psychology, the new assertions have raised widespread interest. (shrink)

Machine vision is one of the main applications of artificial intelligence. In China, the machine vision industry makes up more than a third of the national AI market, and technologies like face recognition, object tracking and automated driving play a central role in surveillance systems and social governance projects relying on the large-scale collection and processing of sensor data. Like other novel articulations of technology and society, machine vision is defined, developed and explained by different actors through (...) the work of imagination. In this article, we draw on the concept of sociotechnical imaginaries to understand how Chinese companies represent machine vision. Through a qualitative multimodal analysis of the corporate websites of leading industry players, we identify a cohesive sociotechnical imaginary of machine vision, and explain how four distinct visual registers contribute to its articulation. These four registers, which we call computational abstraction, human–machine coordination, smooth everyday, and dashboard realism, allow Chinese tech companies to articulate their global ambitions and competitiveness through narrow and opaque representations of machine vision technologies.

Rabbi HaCohen Kook’s essay on vegetarianism and peace, first published in instalments in 1903–4, and reissued 60 years later, is the only treatise in rabbinic Judaism on the relationship between humans and animals. It is here examined as central to his ethical beliefs. His writings, shaped by his background as rabbi and mystic, illuminate the history of environmental and applied ethics. A century ago, he perceived the main challenge that confronts reform movements: multiculturalism.

Few sectors are more ethically contentious than dairy, with debates tending to be polarised between “intensification” and “abolitionist” narratives which often drown out alternative voices operating in-between. This paper examines the marginal spaces occupied by a group of farmers in the United Kingdom who are attempting to move towards what they see as “more ethical” dairying. Drawing on findings from ethnographic research on five farms which have adopted “cow-calf contact rearing”—which focuses on keeping calves with their mothers longer, in opposition (...) to conventional practices of removing them shortly after birth—it asks what values underpin this alternative approach, and how and why “ethical” dairies seek to dairy ethically. To do this, it draws on a feminist epistemology and methodology that sees ethics as situated and contextual, and finds an “ethics of care” to be central to changing entanglements between humans and nonhuman animals. Instead of casting dairy as either “good” or “bad”, it explores the activities of farms which are trying to move towards what they perceive to be “better”, and draws three conclusions: (a) “ethical” dairying demonstrates a heterogeneity of dairy practices which are grounded in “care” and are happening between narrative extremes of intensification versus abolition; (b) although this practice may be, and could be, commodified, farmers are primarily guided by strong ideological principles and influenced by affective and empathetic “entanglements” with cows and calves, the agency of bovines themselves, and their social and ecological environment; and (c) “cow-calf contact rearing” represents a significant shift from a focus on the broader welfare environment towards centring the quality of individual cows’ lives. Ultimately, the paper argues that we should pay greater attention to alternative economies built on an “ethics of care” when envisaging new sustainable food and agricultural systems. (shrink)

Resulta extraño que tanto en las Investigaciones filosóficas como en la mayoría de los trabajos posteriores al Tractatus Logico-philosophicus Ludwig Wittgenstein no mencione explícitamente a la ética ni trate cuestiones relativas a ella.

En segundo lugar, presentaré la nueva forma de pensar de Wittgenstein, que encuentra en las Investigaciones filosóficas su expresión más elaborada. En la última sección del texto intentaré articular de manera coherente con el pensamiento tardío de Wittgenstein los diferentes aspectos respecto a lo ético, que espero destaquen a lo largo de este escrito.

Despite its oft-noted ambiguities, critical reception of Ridley Scott's Blade Runner ; Director's Cut ; Final Cut ) has tended to converge upon seeing it as a futuristic sci-fi film noir whose central concern is what it means to be human, a question that is fraught given the increasingly human-like replicants designed and manufactured by the Tyrell Corporation for human use on off-world colonies. Within the terms of this way of seeing things a great deal of discussion has been devoted (...) to putative criteria of being human and the question whether the once-retired blade runner, Rick Deckard, is or is not a replicant. I aim to explore a radically different course of interpretation, which sees the film in fundamentally moral and religious terms. Put in the starkest light, the film is not about what makes us human but whether we can be saved from ourselves, from our terrifying inhumanity, our moral blindness. (shrink)

Abstract.What we urgently need at the beginning of the twenty‐first century is a christological vision that can shape and inform a new and powerful way of helping humankind to interpret their place within the universe. A christological vision that is unintelligible and uninteresting can have a profoundly deleterious soteriological implication: the orbit of God's saving grace will not be wide enough to encompass the universal place of humankind. Arthur Peacocke's move is clear and to the point: Only when (...) the foundations and universal scope of God's grace are fully established for all of creation, only then can the importance of God's specific work in Jesus the Christ be established.

I argue for the centrality of the concepts of biophysical and human nature in science-and-religion studies, consider five different metaphors, or “visions,” of nature, and explore possibilities and challenges in reconciling them. These visions include (a) evolutionary nature, built on the powerful explanatory framework of evolutionary theory; (b) emergent nature, arising from recent research in complex systems and self-organization; (c) malleable nature, indicating both the recombinant potential of biotechnology and the postmodern challenge to a fixed ontology; (d) nature as (...) sacred, a diffuse popular concept fundamental to cultural analysis; and (e) nature as culture, an admission of epistemological constructivism. These multiple visions suggest the famous story of the blind men and the elephant, in which each man made the classic mistake of part-whole substitution in believing that what he grasped (the tail, for example) represented the elephant as a whole. Indeed, given the inescapability of metaphor, we may have to admit that the ultimate truth about the “elephant” (nature, or the reality toward which science and religion point) is a mystery, and the best we can hope for is to confess the limitations of any particular vision.

In this paper, I discuss substance-induced visions and consider their epistemic status, meaning, and modes of proper interpretation. I focus on the visions induced by ayahuasca, a powerful psychoactive plant-made brew that has had a central status and role in the indigenous tribal cultures of the upper Amazonian region. The brew is especially famous for the visions seen with it. These are often coupled with personal psychological insights, mentations concerning topics of special significance to one, intellectual (notably, philosophical and metaphysical) (...) ideations, as well as powerful religious and spiritual sentiments. Thus, under the intoxication, people often feel that they gain significant knowledge and understanding. The present discussion takes a cognitive-phenomenological perspective coupled with a philosophical analysis of the various epistemological questions at hand. (shrink)

Recently, there has been much interest in epistemic roles of attention, especially in whether visual attention is necessary for warranting (basic) visual belief. Arguably it is not. But attention nevertheless has important roles to play in our warrant from vision. I argue that we must appeal to a competence for shifting visual attention in explaining transsaccadic vision and our epistemic warrant from it. So even if it is not necessary for visual warrant or vision, visual attention plays (...) a central role in both. (shrink)

One necessary condition on any adequate account of perception is clarity regarding whether unconscious perception exists. The issue is complicated, and the debate is growing in both philosophy and science. In this paper we consider the case for unconscious perception, offering three primary achievements. First, we offer a discussion of the underspecified notion of central coordinating agency, a notion that is critical for arguments that purportedly perceptual states are not attributable to the individual, and thus not genuinely perceptual. We develop (...) an explication of what it is for a representational state to be available to central coordinating agency for guidance of behavior. Second, drawing on this explication, we place a more careful understanding of the attributability of a state to the individual in the context of a range of empirical work on vision-for-action, saccades, and skilled typing. The results place pressure on the skeptic about unconscious perception. Third, reflecting upon broader philosophical themes running through debates about unconscious perception, we highlight how our discussion places pressure on the view that perception is a manifest kind, rather than a natural kind. In doing so, we resist the tempting complaint that the debate about unconscious perception is merely verbal. (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)

Peripheral vision has different functional priorities for mammals than foveal vision. One of its roles is to monitor the environment while central vision is focused on the current task. Becoming distracted too easily would be counterproductive in this perspective, so the brain should react to behaviourally relevant changes. Gist processing is good for this purpose, and it is therefore not surprising that evidence from both functional brain imaging and behavioural research suggests a tendency to generalize and blend (...) information in the periphery. This may be caused by the balance of perceptual influence in the periphery between bottom-up and top-down processing channels. Here, we investigated this interaction behaviourally using a peripheral numerosity discrimination task with top-down and bottom-up manipulations. Participants compared numerosity between the left and right peripheries of a screen. Each periphery was divided into a centre and a surrounding area, only one of which was a task relevant target region. Our top-down task modulation was the instruction which area to attend – centre or surround. We varied the signal strength by altering the stimuli durations i.e., the amount of information presented/processed. We found that numerosity perceived in target regions was affected by contextual information in neighbouring areas. This effect appeared as soon as stimulus duration allowed the task to be reliably performed and persisted even at the longest duration. We compared the pattern of results with an ideal-observer model and found a qualitative difference in the way centre and surround areas interacted perceptually in the periphery. When participants reported on the central area, the irrelevant surround would affect the response as a weighted combination – consistent with the idea of a receptive field focused in the target area to which irrelevant surround stimulation leaks in. When participants report on surround, we can best describe the response with a model in which occasionally the attention switches from task relevant surround to task irrelevant centre – consistent with a selection model of two competing streams of information. Overall our results show that the influence of spatial context in the periphery is mandatory but task dependent. (shrink)

A central aspect of the computational theory of vision developed by Marr and his coworkers is the use made of contingent regularities in the physical environment to explain how the visual system determines the shape and location of objects in the world on the basis of the spatial organization of the retinal image. Marr (1982) refers to these environmental regularities as “natural constraints” and “physical assumptions.” In this paper I am concerned with recent arguments concerning the implications of this (...) feature of Marr’s theory for understanding psychological explanation. Burge (1986) claims that Marr’s use of natural constraints shows the theory to be nonindividualistic, in the sense that the individuation of psychological states depends essentially on the objects and conditions of the world external to the subject. While it does capture an important aspect of Marr’s theory, Burge’s account is misleadingly incomplete. To see this it is useful to compare the issue of individualism with the question whether the theory is compatible with methodological solipsism as a research strategy. (shrink)

The purpose of this article is to examine Sellars’s envisaged stereoscopic fusion between the manifest and the scientific image in regard to the central issue of the being of the normative. I shall propose that the best way to make sense of the notion of the Sellarsian ‘stereoscopic fusion’ is to hold both that (a) the core function of normative discourse is to point toward something that does not exist, but ought to exist, namely a regulative ideal and (b) that (...) the raison d’être of normatively infused items is for them to be materially realized at the level of non-normative objects and processes. On this view, the effected elimination (denormativization) of the normative level itself in the Sellarsian ‘synoptic vision’ can be best understood in terms of the concrete realization of what I call ‘generalized absorbed skillful coping,’ that is, our ability for absorbed skillful coping within our—and indeed, in any possible—environment.

Marx believed that what most clearly distinguished him and Engels from the nineteenth-century French socialists was that their version of socialism was “scientific” while the latters' was Utopian. What he intended by this contrast is roughly the following: French socialists such as Proudhon and Fourier constructed elaborate visions of a future socialist society without an adequate understanding of existing capitalist society. For Marx, on the other hand, socialism was not an idea or an ideal to be realized, but a natural (...) outgrowth of the existing capitalist order. Marx's historical materialism is a systematic attempt to discover the laws governing the inner dynamics of capitalism and class societies generally. Although this theory issues in a prediction of the ultimate triumph of socialism, it is a commonplace that Marx had little to say about the details of post-capitalist society. Nevertheless, some of its features can be discerned from his critical analysis of capitalism and what its replacement entails. (shrink)

The essay is concentrated on emotional affects caused by representation of violence in the case of Russia’s war against Ukraine and beyond. Instant accessibility to first-hand visual information created fertile soil for planting and then multiplying manipulative strategies of one or another political interest. Meanwhile, the demand for shocking content continues to steadily rise because it guarantees popularity, spectacle and even a form of pleasure. This, in turn, supports a very propagandistic version of reality where violence plays a central role (...) in the overall design and transmission of contents, which is driven by shock as an affective medium. Blind Spot, Gradual Loss of Vision and Speck in the Eye represent a body of works by Mykola Ridnyi, address the question of what potential response(s) could be given by artistic interventions understood as a dialectical and critical framework able to face and make visible the problem of dehumanization through violence?

In recent years scholars from many disciplines have become interested in the "construction" of the human senses -- in how the human environment shapes both how and what we perceive. Taking a very different approach to the question of construction, Sites of Vision turns to language and explores the ways in which the rhetoric of philosophy has formed the nature of vision and how, in turn, the rhetoric of vision has helped to shape philosophical thought. The central (...) role of vision in relation to philosophy is evident in the vocabulary of the discipline -- in words such as "speculation," "observation," "insight," and "reflection"; in metaphors such as "mirroring," "perspective," and "point of view"; and in methodological concepts such as "reflective detachment" and "representation." Because the history of vision is so pervasively reflected in the history of philosophy, it is possible for both vision and thought to achieve a greater awareness of their genealogy through the history of philosophy. The fourteen contributors to _Sites of Vision_ explore the hypothesis that the nature of visual perception about which philosophers talk must be explicitly recognized as a discursive construction, indeed a historical construction, in philosophical discourse.

Il lavoro consiste in una particolare rilettura del testo cusaniano, nella quale si cerca di evidenziare, tra le altre fonti, soprattutto la presenza di Meister Eckhart. La “discesa” nel fondo dell'anima è presentata come il culmine teoretico di quel cammino di visione a cui e-duca l'aegnima dell'icona. Per queste ragioni l'articolo punta sull'influsso della mistica speculativa in campo teoretico e di quella dottrina che M. Eckhart chiama “Generazione del Logos nell'anima”. Tale trattazione apre poi il senso dell'ampia sezione dedicata alla (...) filosofia negativa e ai “nomi divini” del Deus Trinitas, stavolta sulla scia di Dionigi: Infinito, Non-Aliud e Padre. Centrale è la figura del Cristo, unica vera condizione di possibilità della visione “di” Dio in quanto unico mediatore tra il finito e l'infinito; in Cristo si realizza quella paradossale unione delle due nature ed offre così all'umanità la chiave tanto desiderata per avvicinare l'Infinito.
