Does perceptual consciousness require cognitive access? Ned Block argues that it does not. Central to his case are visual memory experiments that employ post-stimulus cueing—in particular, Sperling's classic partial report studies, change-detection work by Lamme and colleagues, and a recent paper by Bronfman and colleagues that exploits our perception of ‘gist’ properties. We argue contra Block that these experiments do not support his claim. Our reinterpretations differ from previous critics' in challenging as well a longstanding and common view of visual (...) memory as involving declining capacity across a series of stores. We conclude by discussing the relation of probabilistic perceptual representations and phenomenal consciousness. (shrink)

A large part of the contemporary literature on dehumanization is committed to three ideas: (a) dehumanization involves some degree of denial of humanness, (b) such denial is to be comprehended in mental terms, and (c) whatever exact mechanisms underlie the denial of humanness, they belong in the realm of post-perceptual processing. This chapter examines (c) and argues that the awareness of minds might belong to perceptual processing. This paves the way for the possibility that dehumanization might, at least in part, (...) be a perceptual phenomenon, such that dehumanizers visually perceive the dehumanized as exhibiting lesser-than-human minds. It is perhaps unsurprising that the first systematic investigations of dehumanization approached the phenomenon as linked to contexts of war, genocide, extreme hatred, and violence. One guiding hypothesis was that dehumanizers exclude the dehumanized from a moral community of human beings, implicitly conceptualized as displaying distinct individualities and being embedded in caring interpersonal relations. By comprehending the dehumanized as deindividuated entities to which moral norms and considerations of fairness do not apply (Opotow 1990), dehumanizers are able to disengage from moral restrictions and self-sanctions (Bandura 1999).

A SECOND COMPLETELY REVISED EDITION OF THIS TEXTBOOK ON INTERDISCIPLINARY RESEARCH WAS PUBLISHED WITH AMSTERDAM UNIVERSITY PRESS IN 2022. Check out that version here and a PDF of its ToC and Introduction, as this first edition (AUP 2016) is no longer available. [This book (128 pp.) serves as an introduction and manual to guide students through the interdisciplinary research process. We are becoming increasingly aware that, as a result of technological developments and globalisation, problems are becoming so complex that they (...) can only be solved through cooperation between multiple disciplines. Healthcare, climate change, food security, energy, financial markets and quality of life are just a few examples of issues that require scientists and academics to work in a crossdisciplinary way. As a result of these developments, an interdisciplinary approach is becoming increasingly popular in higher education and must be considered an absolute necessity. Young academics are being called on to step beyond the boundaries of traditional disciplines in order to contribute to addressing fundamental problems and solving challenges facing society. There is a need for people who are not afraid to ask critical questions, who can work together well and can look beyond the boundaries of their own field. This means students need to learn more about how they can integrate and apply knowledge, methods and skills from different fields. Interdisciplinary research projects and practical training courses offer students more than one perspective on the same subject. Comparing and contrasting, connecting, adding and adapting concepts, theories and methodologies from different disciplines ultimately results in new insights and better answers to complex problems.].

Is color experience cognitively penetrable? Some philosophers have recently argued that it is. In this paper, we take issue with the claim that color experience is cognitively penetrable. We argue that the notion of cognitive penetration that has recently dominated the literature is flawed since it fails to distinguish between the modulation of perceptual content by non-perceptual principles and genuine cognitive penetration. We use this distinction to show that studies suggesting that color experience can be modulated by factors of the (...) cognitive system do not establish that color experience is cognitively penetrable. Additionally, we argue that even if color experience turns out to be modulated by color-related beliefs and knowledge beyond non-perceptual principles, it does not follow that color experience is cognitively penetrable since the experiences of determinate hues involve post-perceptual processes. We conclude with a brief discussion of the implications that these ideas may have on debates in philosophy. (shrink)

Blindsight and vision for action seem to be exemplars of unconscious visual processes. However, researchers have recently argued that blindsight is not really a kind of uncon- scious vision but is rather severely degraded conscious vision. Morten Overgaard and col- leagues have recently developed new methods for measuring the visibility of visual stimuli. Studies using these methods show that reported clarity of visual stimuli correlates with accuracy in both normal individuals and blindsight patients. Vision for action has also come (...) under scrutiny. Recent findings seem to show that information processed by the dor- sal stream for online action contributes to visual awareness. Some interpret these results as showing that some dorsal stream processes are conscious visual processes (e.g., Gallese, 2007; Jacob & Jeannerod, 2003). The aim of this paper is to provide new support for the more traditional view that blindsight and vision for action are genuinely unconscious per- ceptual processes. I argue that individuals with blindsight do not have access to the kind of purely qualitative color and size information which normal individuals do. So, even though people with blindsight have a kind of cognitive consciousness, visual information process- ing in blindsight patients is not associated with a distinctly visual phenomenology. I argue further that while dorsal stream processing seems to contribute to visual awareness, only information processed by the early dorsal stream (V1, V2, and V3) is broadcast to working memory. Information processed by later parts of the dorsal stream (the parietal lobe) never reaches working memory and hence does not correlate with phenomenal awareness. I con- clude that both blindsight and vision for action are genuinely unconscious visual processes. (shrink)

Perceptual processes, in particular modular processes, have long been understood as being mandatory. But exactly what mandatoriness amounts to is left to intuition. This paper identifies a crucial ambiguity in the notion of mandatoriness. Discussions of mandatory processes have run together notions of automaticity and ballisticity. Teasing apart these notions creates an important tool for the modularist's toolbox. Different putatively modular processes appear to differ in their kinds of mandatoriness. Separating out the automatic from the ballistic (...) can help the modularist diagnose and explain away some putative counterexamples to multimodal and central modules, thereby helping us to better evaluate the evidentiary status of modularity theory.

Multisensory processing encompasses all of the various ways in which the presence of information in one sensory modality can adaptively influence the processing of information in a different modality. In Part I of this survey article, I begin by presenting a cartography of some of the more extensively investigated forms of multisensory processing, with a special focus on two distinct types of multisensory integration. I briefly discuss the conditions under which these different forms of multisensory processing occur as well as (...) their important perceptual consequences and interrelations. In Part II, I then turn to examining of some of the different possible ways in which the structure of conscious perceptual experience might also be characterized as multisensory. In addition, I discuss the significance of research on multisensory processing and multisensory consciousness for philosophical attempts to individuate the senses. (shrink)

Is consciousness based in prefrontal circuits involved in cognitive processes like thought, reasoning, and memory or, alternatively, is it based in sensory areas in the back of the neocortex? The no-report paradigm has been crucial to this debate because it aims to separate the neural basis of the cognitive processes underlying post-perceptual decision and report from the neural basis of conscious perception itself. However, the no-report paradigm is problematic because, even in the absence of report, subjects might engage (...) in post-perceptual cognitive processing. Therefore, to isolate the neural basis of consciousness, a no-cognition paradigm is needed. Here, I describe a no-cognition approach to binocular rivalry and outline how this approach can help resolve debates about the neural basis of consciousness. (shrink)

The first part of this survey article presented a cartography of some of the more extensively studied forms of multisensory processing. In this second part, I turn to examining some of the different possible ways in which the structure of conscious perceptual experience might also be characterized as multisensory. In addition, I discuss the significance of research on multisensory processing and multisensory consciousness for philosophical debates concerning the modularity of perception, cognitive penetration, and the individuation of the senses.

A central debate in philosophy and neuroscience pertains to whether PFC activity plays an essential role in the neural basis of consciousness. Neuroimaging and electrophysiology studies have revealed that the contents of conscious perceptual experience can be successfully decoded from PFC activity, but these findings might be confounded by post- perceptual cognitive processes, such as thinking, reasoning, and decision-making, that are not necessary for con- sciousness. To clarify the involvement of the PFC in consciousness, we present a synthesis of (...) research that has used intracranial electrical stimulation (iES) for the causal modulation of neural activity in the human PFC. This research provides compelling evidence that iES of only certain prefrontal regions (i.e., orbitofrontal cortex and anterior cingu- late cortex) reliably perturbs conscious experience. Conversely, stimulation of anterolateral prefrontal sites, often con- sidered crucial in higher-order and global workspace theories of consciousness, seldom elicits any reportable alterations in consciousness. Furthermore, the wide variety of iES-elicited effects in the PFC (e.g., emotions, thoughts, and olfactory and visual hallucinations) exhibits no clear relation to the immediate environment. Therefore, there is no evidence for the kinds of alterations in ongoing perceptual experience that would be predicted by higher-order or global workspace theories. Nevertheless, effects in the orbitofrontal and anterior cingulate cortices suggest a specific role for these PFC subregions in supporting emotional aspects of conscious experience. Overall, this evidence presents a challenge for higher-order and global workspace theories, which commonly point to the PFC as the basis for con- scious perception based on correlative and possibly confounded information.

The goal of this piece is to put some pressure on Brian O’Shaughnessy’s claim that perceptual experiences are necessarily mental processes. The author targets two motivations behind the development of that view. First, O’Shaughnessy resorts to pure conceptual analysis to argue that perceptual experiences are processes. The author argues that this line of reasoning is inconclusive. Secondly, he repeatedly invokes a thought experiment concerning the total freeze of a subject’s experiential life. Even if this case is coherent, however, (...) it does not show that perceptual experiences are processes. (shrink)

Predictive Processing theory, hotly debated in neuroscience, psychology and philosophy, promises to explain a number of perceptual and cognitive phenomena in a simple and elegant manner. In some of its versions, the theory is ambitiously advertised as a new theory of conscious perception. The task of this paper is to assess whether this claim is realistic. We will be arguing that the Predictive Processing theory cannot explain the transition from unconscious to conscious perception in its proprietary terms. The explanations offer (...) by PP theorists mostly concern the preconditions of conscious perception, leaving the genuine material substrate of consciousness untouched. (shrink)

In this paper, I argue that theories of perception that appeal to Helmholtz’s idea of unconscious inference (“Helmholtzian” theories) should be taken literally, i.e. that the inferences appealed to in such theories are inferences in the full sense of the term, as employed elsewhere in philosophy and in ordinary discourse. -/- In the course of the argument, I consider constraints on inference based on the idea that inference is a deliberate acton, and on the idea that inferences depend on the (...) syntactic structure of representations. I argue that inference is a personal-level but sometimes unconscious process that cannot in general be distinguished from association on the basis of the structures of the representations over which it’s defined. I also critique arguments against representationalist interpretations of Helmholtzian theories, and argue against the view that perceptual inference is encapsulated in a module. (shrink)

Cognitive penetration of perception, broadly understood, is the influence that the cognitive system has on a perceptual system. The paper shows a form of cognitive penetration in the visual system which I call ‘architectural’. Architectural cognitive penetration is the process whereby the behaviour or the structure of the perceptual system is influenced by the cognitive system, which consequently may have an impact on the content of the perceptual experience. I scrutinize a study in perceptual learning that provides empirical evidence that (...) cognitive influences in the visual system produce neural reorganization in the primary visual cortex. The type of cognitive penetration can be synchronic and diachronic. (shrink)

The basis of perception is the processing and categorization of perceptual stimuli from the environment. Much progress has been made in the science of perceptual categorization. Yet there is still no consensus on how the brain generates sensory individuals, from sensory input and perceptual categories in memory. This chapter argues that perceptual categorization is highly variable across perceivers due to their use of different perceptual strategies for solving perceptual problems they encounter, and that the perceptual system structurally adjusts to the (...) strategies that are most successful. Despite this variability, the different sensory individuals that result when different perceivers rely on different strategies nonetheless correspond to actual external world objects/features. This view is called 'perceptual pluralism'. (shrink)

Can perceptual experiences be states of uncertainty? We might expect them to be, if the perceptual processes from which they're generated, as well as the behaviors they help produce, take account of probabilistic information. Yet it has long been presumed that perceptual experiences purport to tell us about our environment, without hedging or qualifying. Against this long-standing view, I argue that perceptual experiences may well occasionally be states of uncertainty, but that they are never probabilistically structured. I criticize a (...) powerful line of reasoning that we should expect perceptual experience to be probabilistic, given their interfaces with unconscious probabilistic information, with behavior responsive to it, and with credences.

Perceptual modalities have been traditionally considered the product of dedicated biological systems producing information for higher cognitive processing. Psychological and neuropsychological evidence is offered which undermines this point of view and an alternative account of modality from the enactive approach to understanding cognition is suggested. Under this view, a perceptual modality is a stable form of perception which is structured not just by the biological sensitivities of the agent, but by their goals and the set of skills or expertise which (...) they are deploying at a given time. Such a view suggests that there is no such thing as an experience that is purely visual, auditory, or otherwise modal and that our attempts to understand consciousness and the mind must be conducted within a framework that provides an account of embodied, goal-directed adaptive coping with the world.

Post-truth has an impression that the facts have been only corrupted with it. Many examples support this impression. However, it should not be perceived as just a disruption of the truth considering only political events. In different fields, such as creative industries, it may have different implications. Despite studies regarding education, there has not been much discussion on the design process and education. The objective of this research is to develop an introductory examination of what the design process (with statements (...) in the book 'How Designers Think') can produce in post-truth cases and to seek the productive potentials of post-truth. Therefore, the claims were reviewed - as design problems, solutions and process itself - within the framework of the post-truth era. Some of the results are as follows: For design problems, designers need to find a way to oscillate among objectives without based on truth. Post-truth environments may trigger finding out unique spatial possibilities with designs of unique hierarchies. For design solutions, in post-truth era, the only optimal thing is to be apathetic about truth. There is no need to seek the optimal solutions. The ideal of wholeness is expired for the solutions. This situation fosters free circulations of tiny parts of solutions in the post-truth universe. For the design process, the correctness of the process is much more questionable anymore. Identifying problem is a crucial part of the design process. As the truth disappears, it becomes more difficult to discriminate the characteristics and value of the problems. (shrink)

Theories of consciousness divide over whether perceptual consciousness is rich or sparse in specific representational content and whether it requires cognitive access. These two issues are often treated in tandem because of a shared assumption that the representational capacity of cognitive access is fairly limited. Recent research on working memory challenges this shared assumption. This paper argues that abandoning the assumption undermines post-cue-based “overflow” arguments, according to which perceptual conscious is rich and does not require cognitive access. Abandoning it also (...) dissociates the rich/sparse debate from the access question. The paper then explores attempts to reformulate overflow theses in ways that don’t require the assumption of limited capacity. Finally, it discusses the problem of relating seemingly non-probabilistic perceptual consciousness to the probabilistic representations posited by the models that challenge conceptions of cognitive access as capacity-limited.

Proponents of cognitive penetration often argue for the thesis on the basis of combined intuitions about categorical perception and perceptual learning. The claim is that beliefs penetrate perceptions in the course of learning to perceive categories. I argue that this "diachronic" penetration thesis is false. In order to substantiate a robust notion of penetration, the beliefs that enable learning must describe the particular ability that subjects learn. However, they cannot do so, since in order to help with learning they must (...) instruct learners to employ previously existing abilities. I argue that a better approach recognizes that we can have sophisticated causal precursors to perceptual learning, but that the learning process itself must operate outside of cognitive influence.

In the paper I argue that medieval philosophers proposed several notions of the senses’ activity in perception. I illustrate the point using the example of two Franciscan thinkers – Peter Olivi (ca. 1248–1298) and Peter Auriol (ca. 1280–1322). Olivi’s notion of active perception assumes that every perceptual act demands a prior focusing of the mind’s attention. Furthermore, Olivi is partially inspired by the extramissionist theories of vision and reinterprets the notion of a visual ray postulated by them as a useful (...) model for explaining attention and attentional shifts. In Auriol’s view, perception is active because it participates in producing a perceptual content. e senses not only receive information from the environment, they also actively process it and, in Auriol’s words, put the external object into apparent being. e peculiar feature of Auriol’s account is his obvious tendency to conceive perceptual content as both dependent on our perceptual activity and external to the senses. Finally, I consider the two theories in the context of mirror perception – while Olivi focused on the ability of mirrors to switch attention’s direction, Auriol investigated the metaphysical nature of mirror images.

Many philosophers take experience to be an essential aspect of perceptual justification. I argue against a specific variety of such an experientialist view, namely, the Looks View of perceptual justification, according to which our visual beliefs are mediately justified by beliefs about the way things look. I describe three types of cases that put pressure on the idea that perceptual justification is always related to looks-related reasons: unsophisticated cognizers, multimodal identification, and amodal completion. I then provide a tentative diagnosis of (...) what goes wrong in the Looks View: it ascribes a specific epistemic role to beliefs about looks that is actually fulfilled by subpersonal perceptual processes.

The article entitled “Post-COVID-19: Education and Thai Society in Digital Era” has two objectives: 1) to study digital technology 2) to study the living life in Thailand in the digital era after COVID-19 pandemics. According to the study, it was found that the new digitized service is a service process on digital platforms such as ordering food, hailing a taxi, and online trading. It is a service called via smartphone. The information is used digitally. Public relations, digital marketing, and living (...) in cyberspace play an increasingly digital role. People have communication skills, use Line, Facebook, social media, have tools to search for knowledge, learn and improve themselves. People in the new era of life have a new way of life therefore there is social life in the cyber world. There should be ethics, attitudes, values, and click-on images that are linked to digital use. For a good time life, It is important to have digital intelligence (Digital Quotient) to live after post-COVID19, the digital era. (shrink)

Assuming a radical stance on embodied cognition, according to which the information ac- quired through basic cognitive processes is not contentful (Hutto and Myin, 2013), and as- suming that perception is a source of rationally grounded knowledge (Pritchard, 2012), a pluralistic account of perceptual knowledge is developed. The paper explains: (i) how the varieties of perceptual knowledge fall under the same broader category; (ii) how they are subject to the same kind of normative constraints; (iii) why there could not (...) be a conflict between the different varieties of perceptual knowledge; and (iv) why the traditional episte- mological inquiry is inclined to overestimate the role of propositional perceptual knowledge.

When a user integrates a sensory substitution device into her life, the process involves perceptual learning, that is, ‘relatively long-lasting changes to an organism’s perceptual system that improve its ability to respond to its environment’ (Goldstone 1998: 585). In this paper, I explore ways in which the extensive literature on perceptual learning can be applied to help improve sensory substitution devices. I then use these findings to answer a philosophical question. Much of the philosophical debate surrounding sensory substitution devices concerns (...) what happens after perceptual learning occurs. In particular, should the resultant perceptual experience be classified in the substituted modality (as vision), in the substituting modality (as auditory or tactile), or in a new sense modality? I propose a novel empirical test to help resolve this philosophical debate. (shrink)

Since the time Nietzsche declared the death of God, while Auguste Comte postulated in the Law of Three Stages that humankind had gone pass the religious/mythical stage as well as the metaphysical/speculative stage and was now living in the positive/scientific stage, there has been the consistent institutionalization of atheism and secularism. The early part of the 20th century saw Freud’s publication of the Future of an Illusion in which he predicted that as science continues to advance, religion will become obsolete. (...) The logical positivist too lumped up metaphysical and religious propositions as meaningless and nonsensical. It is within this atmosphere that Alfred North Whitehead comes into philosophy. The main question that this paper seeks to answer is: Why does the concept of God occupy an eminent place in Whitehead’s system when all his contemporaries consider God a hypothesis they no longer needed as Laplace had earlier maintained? Of great interest here is the fact that before 1925 Whitehead’s writings had no concern for God. However, in his 1925 Science and the Modern World, the chapter on “Abstractions” required that there be such an explanatory factor, reason for which it is immediately followed by the chapter on “God”. The last part of his Process and Reality treats elaborately the nature of the relationship between God and the world. This paper explores the reasons why Whitehead places a lot of interest on God and the role that this God plays in his system. (shrink)

This paper introduces post-place branding in the context of the post-representationalist turn in marketing research by drawing on Deleuze and Guattari’s (A thousand plateaus: capitalism and schizophrenia, University of Minnesota Press, Minneapolis, 1987) theory of nomadology. By engaging critically with fundamental concepts in the place and destination branding literature, post-place branding offers an alternative perspective to entrenched definitions of subjectivity, place, and event experiencing, by effecting a paradigmatic shift from processing monad to nomad, from event as symbolic structure to micro-events, (...) from pre-constituted place to spacing in the process of deand reterritorializations. Post-place branding is illustrated by re-imagining the brand architectural components of the experiential events of 70,000 Tons of Metal and The Boiler Room. The analysis culminates in a metaphorical modeling exercise that draws nomadological guidelines for brandcomms’ message strategy. (shrink)

This chapter explores to what extent some core ideas of predictive processing can be applied to the phenomenology of time consciousness. The focus is on the experienced continuity of consciously perceived, temporally extended phenomena (such as enduring processes and successions of events). The main claim is that the hierarchy of representations posited by hierarchical predictive processing models can contribute to a deepened understanding of the continuity of consciousness. Computationally, such models show that sequences of events can be represented as (...) states of a hierarchy of dynamical systems. Phenomenologically, they suggest a more fine-grained analysis of the perceptual contents of the specious present, in terms of a hierarchy of temporal wholes. Visual perception of static scenes not only contains perceived objects and regions but also spatial gist; similarly, auditory perception of temporal sequences, such as melodies, involves not only perceiving individual notes but also slightly more abstract features (temporal gist), which have longer temporal durations (e.g., emotional character or rhythm). Further investigations into these elusive contents of conscious perception may be facilitated by findings regarding its neural underpinnings. Predictive processing models suggest that sensorimotor areas may influence these contents. (shrink)

Although symmetry has been discussed in terms of a major law of perceptual organization since the early conceptual efforts of the Gestalt school (Wertheimer, Metzger, Koffka and others), the first quantitative measurements testing for effects of symmetry on processes of Gestalt formation have seen the day only recently. In this study, a psychophysical rating study and a “foreground”-“background” choice response time experiment were run with human observers to test for effects of bilateral symmetry on the perceived strength of figure-ground (...) in triangular Kanizsa configurations. Displays with and without bilateral symmetry, identical physically-specified-to-total contour ratio, and constant local contrast intensity within and across conditions, but variable local contrast polarity and variable orientation in the plane, were presented in a random order to human observers. Configurations with bilateral symmetry produced significantly stronger figure-ground percepts reflected by greater subjective magnitudes and consistently higher percentages of “foreground” judgments accompanied by significantly shorter response times. These effects of symmetry depend neither on the orientation of the axis of symmetry, nor on the contrast polarity of the physical inducers. It is concluded that bilateral symmetry, irrespective of orientation, significantly contributes to the, largely sign-invariant, visual mechanisms of figure-ground segregation that determine the salience of figure-ground in perceptually ambiguous configurations.

Since the advent of media archeology, a deep-seated bifurcation has found one end of the field arguing for the interventionist and appropriative weaponization of media whereas the other side has championed a “total war” with technology itself, insisting that new media’s military-industrial roots inherently color its drivability. Here, I implore a moment within the cultural history of net.art and post-internet art to examine how contemporaneous queries about control after militarism and decentralization, as prognosticated by Paul Virilio and Gilles Deleuze, are (...) part of a more deeply entrenched discourse on neural nets, predictive processing algorithms and machine learning, which the current media theory and post-cinema literature has yet to rigorously respond to. Simultaneously parsing philosophical and media sociology corollaries to ground this overview, I push for more attention towards psychopower, autosurveillance and algorithmic governmentality while distancing critique from the standard Foucauldian discourse of biopower.

Sense experience, naïvely conceived, is a way of knowing perceptible properties: the colors, sounds, smells, flavors, and textures in our perceptual environment. So conceived, ordinary experience presents the perceiver with the essential nature of a property like Sky Blue or Middle C, such that how the property appears in experience is identical to how it essentially is. In antiquity, as today, it was controversial whether sense experience could meet the conditions for knowledge implicit in this naïve conception. Aristotle was a (...) partisan in this debate, but his position is poorly understood. This dissertation examines how Aristotle’s perceptual psychology responds to ancient challenges to the naïve conception, and so articulates his defense of perceptual knowledge. -/- Aristotle’s defense relies on an ontology of “perceptual qualities"—a core class of perceptible properties—according to which those qualities, despite having a perceiver-independent essence rooted in the physics of causation and affection, nevertheless can be present in experience as they essentially are. Chapter 1 defends this realist and objectivist reading against competing interpretations, which overlook a crucial distinction between perceptual qualities and perceptual objects. Chapter 2 presents Aristotle’s ontology as a physicalism that uncharacteristically allows for perceptual qualities to appear in experience as they essentially are. -/- This ontology informs Aristotle’s account of the psychological conditions under which perceivers actually are presented with the essence of perceptual qualities. The locus of this account is an obscure passage where Aristotle purports to show that the senses “discriminate” perceptual qualities because the senses are “mean states” (An. 2.11, 424a5–7). Chapter 3 develops a comprehensive interpretation of the sensory mean state, which Chapter 4 uses to elucidate Aristotle’s argument for sensory discrimination. Sensory discrimination turns out to be a process in which the essence of a perceptual quality comes to be present in the affection it produces in a perceiver. For Aristotle, this shows that sense perception meets a condition for knowledge that his predecessors, including Plato, thought it could not meet. For in his view, but not in theirs, sense experience shares in both the truth and the essence of the qualities it perceives. (shrink)

It is often claimed that epistemic bubbles and echo chambers foster post-truth by filtering our access to information and manipulating our epistemic attitude. In this paper, I try to add a further level of analysis by adding the issue of belief formation. Building on cognitive psychology work, I argue for a dual-system theory according to which beliefs derive from a default system and a critical system. One produces beliefs in a quasi-automatic, effortless way, the other in a slow, effortful way. (...) I also argue that digital socio-epistemic environments tend to inculcate disvalues in their agent's epistemic identity, a process that causes the cognitive shortcircuits typical of conspiracy theories.

The overwhelming majority of Albania’s urban population is located in Tirana, a city with a very dynamic socio-spatial reality, resulting as an entry point for people from various origins, including multicultural rural societies, and has significant concentrations of finance and other economic activities. Urban areas demonstrate the dynamics that impact society from many angles, including those related to technology, economics, demographics, and culture, via a diverse and changed perspective. Since 1991, there has been a growing separation between classes, genders, and (...) regions, as well as between individuals and vulnerable groups, due to a lack of social protection and governmental measures for these groups and individuals, and the unrestricted power of the free market. Today, there is a noticeable improvement in the real pattern of social group concentration. This paper focuses on various divisions of social groupings in Tirana, how they are reflected in the city’s everyday life, and how they trend to the fragmentation of contemporary urban regions. In order to comprehend the change over time and transition patterns of Tirana from sites of production to places of consumption, the process method is modified by concentrating on the main stakeholders. The background of enhancing cities’ mobility and competitiveness demonstrates the interaction between different social groups and different living patterns in Tirana. The study also shows the socio-spatial pattern of the new city. The significant level of social fragmentation in Tirana is evident from analysis that only investigated a certain percentage of the city’s social groupings. The new master plans predicted in the city will help to overcome the issue. (shrink)

The chapter outlines an abstract theoretical framework that is currently (re-)emerging in the course of a theoretical convergence of several disciplines. In the first section, the fundamental problem of perception theory is formulated, namely, the generation, by the perceptual system, of meaningful categories from physicogeometric energy patterns. In the second section, it deals with basic intuitions and assumptions underlying what can be regarded as the current Standard Model of Perceptual Psychology and points out why this model is profoundly inadequate for (...) dealing with the fundamental problem of perception theory. In the third section, it discusses a level of analysis that promises to be fruitful for dealing, in conformity with established procedures of the natural sciences, with the problem of perceptual “meaning” and the problem of what constitutes a “perceptual object.” In the fourth section, it outlines a theoretical perspective on basic principles of the perceptual system which centers on the notions of complex data types and conceptual forms, and draws an entirely different theoretical picture of the role of the sensory input than traditional accounts. The final section focusses on the issue of material qualities and discusses, within the general theoretical framework outlined, some observations and results on the perception of certain material properties, namely, lustrous and glassy appearances.

The aim of the study is to spell out and consider Plato' s views on perceptual cog­nition. It is argued that Plato is cornrnitted to the view that perceptual cognition can be rational, and that beliefs about the sensible world need not be confused or ill-founded. Plato' s interest in the matter arises from worries over the way in which his fore­runners and contemporaries conceived of perceptual cognition. They conceived of cognitive processes in terms of corporeal changes and attempted (...) to explain perceptual cognition in causal terms. The problem with such accounts, according to Plato, is that they make perceptual cognition an entirely passive process, and seem incapable of accommodating the freedom of reason. Plato's main target is Protagoras' view on cognition and he accuses him of con­flating different cognitive phenomena that ought to be kept apart. More particularly, he suggests that Protagoras' 'man the measure' thesis is based on the conflation of sen se perception, belief and appearing, and that Protagoras is cornmitted to the view that beliefs are arrived at in a non-rational way. It is shown how Plato takes issue with Protagoras by disentangling these three cognitive phenomena. It is argued that Plato' s way of understanding these notions leaves room for the possibility that reason plays apart in perceptual cognition and that we arrive at beliefs in a rational way. In the course of spelling out the argument, Plato' s views on a number of topics are scrutinised: the perceptual mechanism; the objects of sense perception; perceptual content; the nature of belief; the eon trast between belief and appearing; the nation of reason.

The discipline of knowledge translation (KT) emerged as a way of systematically understanding and addressing the challenges of applying health and medical research in practice. In light of ongoing and emerging critique of KT from the medical humanities and social sciences disciplines, KT researchers have become increasingly aware of the complexity of the translational process, particularly the significance of culture, tradition and values in how scientific evidence is understood and received, and thus increasingly receptive to pluralistic notions of knowledge. Hence, (...) there is now an emerging view of KT as a highly complex, dynamic, and integrated sociological phenomenon, which neither assumes nor creates knowledge hierarchies and neither prescribes nor privileges scientific evidence. Such a view, however, does not guarantee that scientific evidence will be applied in practice and thus poses a significant dilemma for KT regarding its status as a scientific and practice-oriented discipline, particularly within the current sociopolitical climate. Therefore, in response to the ongoing and emerging critique of KT, we argue that KT must provide scope for relevant scientific evidence to occupy an appropriate position of epistemic primacy in public discourse. Such a view is not intended to uphold the privileged status of science nor affirm the “scientific logos” per se. It is proffered as a counterbalance to powerful social, cultural, political and market forces that are able to challenge scientific evidence and promote disinformation to the detriment of democratic outcomes and the public good.

Victor Vasarely's (1906–1997) important legacy to the study of human perception is brought to the forefront and discussed. A large part of his impressive work conveys the appearance of striking three-dimensional shapes and structures in a large-scale pictorial plane. Current perception science explains such effects by invoking brain mechanisms for the processing of monocular (2D) depth cues. Here in this study, we illustrate and explain local effects of 2D color and contrast cues on the perceptual organization in terms of figure-ground (...) assignments, i.e. which local surfaces are likely to be seen as “nearer” or “bigger” in the image plane. Paired configurations are embedded in a larger, structurally ambivalent pictorial context inspired by some of Vasarely's creations. The figure-ground effects these configurations produce reveal a significant correlation between perceptual solutions for “nearer” and “bigger” when other geometric depth cues are missing. In consistency with previous findings on similar, albeit simpler visual displays, a specific color may compete with luminance contrast to resolve the planar ambiguity of a complex pattern context at a critical point in the hierarchical resolution of figure-ground uncertainty. The potential role of color temperature in this process is brought forward here. Vasarely intuitively understood and successfully exploited the subtle context effects accounted for in this paper, well before empirical investigation had set out to study and explain them in terms of information processing by the visual brain.

I. EXECUTIVE SUMMARY The MRCT Center Post-trial Responsibilities: Continued Access to an Investigational Medicine Framework outlines a case-based, principled, stakeholder approach to evaluate and guide ethical responsibilities to provide continued access to an investigational medicine at the conclusion of a patient’s participation in a clinical trial. The Post-trial Responsibilities (PTR) Framework includes this Guidance Document as well as the accompanying Toolkit. A 41-member international multi-stakeholder Workgroup convened by the Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard University (...) (MRCT Center) developed this Guidance and Toolkit. Project Motivation A number of international organizations have discussed the responsibilities stakeholders have to provide continued access to investigational medicines. The World Medical Association, for example, addressed post-trial access to medicines in Paragraph 34 of the Declaration of Helsinki (WMA, 2013): “In advance of a clinical trial, sponsors, researchers and host country governments should make provisions for post-trial access for all participants who still need an intervention identified as beneficial in the trial. This information must also be disclosed to participants during the informed consent process.” This paragraph and other international guidance documents converge on several consensus points: • Post-trial access (hereafter referred to as “continued access” in this Framework [for terminology clarification – see definitions]) is the responsibility of sponsors, researchers, and host country governments; • The plan for continued access should be determined before the trial begins, and before any individual gives their informed consent; • The protocol should delineate continued access plans; and • The plan should be transparent to potential participants and explained during the informed consent process. -/- However, there is no guidance on how to fulfill these responsibilities (i.e., linking specific responsibilities with specific stakeholders, conditions, and duration). To fill this gap, the MRCT Center convened a working group in September of 2014 to develop a framework to guide stakeholders with identified responsibilities. This resultant Framework sets forth applicable principles, approaches, recommendations and ethical rationales for PTR regarding continued access to investigational medicines for research participants.

Reality exists independently of human observers, but does the same apply to its structure? Realist ontologies usually assume so: according to them, the world consists of objects, these have properties and enter into relations with each other, more or less as we are accustomed to think of them. Against this view, Rein Raud develops a radical process ontology that does not credit any vantage point, any scale or speed of being, any range of cognitive faculties with the privilege to judge (...) how the world ‘really’ is. In his view, what we think of as objects are recast as fields of constitutive tensions, cross-sections of processes, never in complete balance but always striving for it and always reconfiguring themselves accordingly. The human self is also understood as a fluctuating field, not limited to the mind but distributed all over the body and reaching out into its environment, with different constituents of the process constantly vying for control. The need for such a process philosophy has often been voiced, but rarely has there been an effort to develop it in a systematic and rigourous manner that leads to original accounts of identity, continuity, time, change, causality, agency and other topics. Throughout his new book, Raud engages with an unusually broad range of philosophical schools and debates, from New Materialism and Object-Oriented Ontology to both phenomenological and analytical philosophy of mind, from feminist philosophy of science to neurophilosophy and social ontology. Being in Flux will be of interest to students and scholars in philosophy and the humanities generally and to anyone interested in current debates about realism, materialism and ontology. (shrink)

La structure du comportement details consciousness-nature relations by navigating between realist and intellectualist alternatives. A phenomenological reading of form guides its attempt to formulate a view that does not reduce consciousness to matter or perceptual structure to a product of mind. I show that this strategy relies on hitherto overlooked idealist commitments. Forms are perceived objects whose intentional structure is intelligibly organized. Having denied that forms are constituted by mind or emergent from matter, Merleau-Ponty likens form-constitution to an ideal process (...) of intentional self-organization. Despite recognizing that Gestalt psychology develops fruitful models of perceptual self-organization, and adopting the transcendental view that form is significant for consciousness, his revisionary interpretation of form outstrips these accounts’ ontologies of mind and nature, and is better understood in light of a post-Kantian philosophical heritage. These results cast Merleau-Ponty’s relation to the Gestalt, post-Kantian, and phenomenological traditions in new light, challenge naturalizing interpretations of Structure, and motivate a rethinking of the status of metaphysics in his early thought.

This article seeks the origin, in the theories of Ibn al-Haytham (Alhazen), Descartes, and Berkeley, of two-stage theories of spatial perception, which hold that visual perception involves both an immediate representation of the proximal stimulus in a two-dimensional ‘‘sensory core’’ and also a subsequent perception of the three dimensional world. The works of Ibn al-Haytham, Descartes, and Berkeley already frame the major theoretical options that guided visual theory into the twentieth century. The field of visual perception was the first area (...) of what we now call psychology to apply mathematics, through geometrical models as used by Euclid, Ptolemy, Ibn al-Haytham, and Descartes (among others). The article shows that Kepler’s discovery of the retinal image, which revolutionized visual anatomy and entailed fundamental changes in visual physiology, did not alter the basic structure of theories of spatial vision. These changes in visual physiology are advanced especially in Descartes' Dioptrics and his L'Homme. Berkeley develops a radically empirist theory vision, according to which visual perception of depth is learned through associative processes that rely on the sense of touch. But Descartes and Berkeley share the assertion that there is a two-dimensional sensory core that is in principle available to consciousness. They also share the observation that we don't usually perceived this core, but find depth and distance to be phenomenally immediate, a point they struggle to accommodate theoretically. If our interpretation is correct, it was not a change in the theory of the psychology of vision that engendered the idea of a sensory core, but rather the introduction of the theory into a new metaphysical context.

Is vision merely a state of the beholder’s sensory organ which can be explained as an immediate effect caused by external sensible objects? Or is it rather a successive process in which the observer actively scanning the surrounding environment plays a major part? These two general attitudes towards visual perception were both developed already by ancient thinkers. The former is embraced by natural philosophers (e.g., atomists and Aristotelians) and is often labelled “intromissionist”, based on their assumption that vision is an (...) outcome of the causal influence exerted by an external object upon a sensory organ receiving an entity from the object. The latter attitude to vision as a successive process is rather linked to the “extramissionist” theories of the proponents of geometrical optics (such as Euclid or Ptolemy) who suggest that an entity – a visual ray – is sent forth from the eyes to the object. The present paper focuses on the contributions to this ancient controversy proposed by some 13th-century Latin thinkers. [...]. (shrink)

This article recapitulates and develops the attempts in the Nietzschean traditions to address and overcome the proliferation of nihilism that Nietzsche predicted to unfold in the next 200 years (WP 2). Nietzsche approached nihilism not merely as a psychology but as a labyrinthic and pervasive historical process whereby the highest values of culture and founding assumptions of philosophical thought prevented the further flourishing of life. Therefore, he thought nihilism had to be encountered and experienced on many, often opposing, fronts to (...) be fully consumed and left behind. Thus, just as Nietzsche captured the subtle reinventions of nihilism in new forms in his time, in the new doers assumed behind new deeds (WP 488), this article focuses on the contemporary tectonic shifts brought by digital technology and challenges subjectivation and narrativization of algorithmic will to power in human-like interfaces such as ChatGPT. Having identified philosophers and himself as the most advanced nihilists in their overvaluation of truth, in the 4th part of Thus Spoke Zarathustra, Nietzsche grappled with the difficult, perhaps impossible, temporality of post-nihilistic historicity that oscillates between highest creativity and highest truths, especially in the sections entitled The Shadow and At Noon whereby he explored new temporal techniques to evade the relapses into temporal nihilisms of the notions of linear progress or eternity (TSZ, 4). By drawing on this juncture, this article offers ways to address transfigurations of nihilism behind new technological performances of subjectivity. The article points toward creative temporalities beyond narrativity and subjectivity insofar as the statistical operations and probabilistic estimations of language-models exceed grammatical construction of meaning. This multifaceted application of his thought on the contemporary ontic reality is necessary to perceive our comet's incalculable movement as a veritable ray of sunshine. (shrink)

The overwhelming majority of Albania’s urban population is located in Tirana, a city with a very dynamic socio-spatial reality, resulting as an entry point for people from various origins, including multicultural rural societies, and has significant concentrations of finance and other economic activities. Urban areas demonstrate the dynamics that impact society from many angles, including those related to technology, economics, demographics, and culture, via a diverse and changed perspective. Since 1991, there has been a growing separation between classes, genders, and (...) regions, as well as between individuals and vulnerable groups, due to a lack of social protection and governmental measures for these groups and individuals, and the unrestricted power of the free market. Today, there is a noticeable improvement in the real pattern of social group concentration. This paper focuses on various divisions of social groupings in Tirana, how they are reflected in the city’s everyday life, and how they trend to the fragmentation of contemporary urban regions. In order to comprehend the change over time and transition patterns of Tirana from sites of production to places of consumption, the process method is modified by concentrating on the main stakeholders. The background of enhancing cities’ mobility and competitiveness demonstrates the interaction between different social groups and different living patterns in Tirana. The study also shows the socio-spatial pattern of the new city. The significant level of social fragmentation in Tirana is evident from analysis that only investigated a certain percentage of the city’s social groupings. The new master plans predicted in the city will help to overcome the issue. (shrink)

Can matter, things, nonhuman organisms, technologies, tools and machines, biota or institutions be seen as creative? How does such creativity reposition the visionary activities of humans? This article is an elaboration of such questions as well as an attempt at a partial response. It was written as an editorial for the special issue of the Digital Creativity journal that interrogates the conception of Post-Anthropocentric Creativity. However, the text below is a rather unconventional editorial. It does not attempt to provide an (...) overview of the issue’s theme but, instead, samples it via a particular example. The idea of the issue was to think about post-anthropocentricism by considering (1) agents, recipients and processes of creativity alongside with its (2) purpose, value, ethics and politics. This article addresses the first subtheme by puzzling at the paradoxes of “field learning” and picks at the second by considering the texture of “automated beauty”. Both of these parts use chess for an example. The narrative on chess is intermitted by a section “on creativity” that attempts to contextualize the case-based discussion in the wider context and to consider motivations and implications.

The present paper was written as a contribution to ongoing methodological debates within the NCC project. We focus on the neural correlates of conscious perceptual episodes. Our claim is that the NCC notion, as applied to conscious perceptual episodes, needs to be reconceptualized. It mixes together the processing related to the perceived contents and the neural substrate of consciousness proper, i.e. mechanisms making the perceptual contents conscious. We thus propose that the perceptual NCC be divided into two constitutive subnotions. The (...) main theoretical idea that emerges as a consequence of this reconceptualization is that the neural correlate of a perceptual episode is formed in the neural interaction between content-processing and consciousness-conferring mechanisms. The paper elaborates this distinction, marshals some initial arguments in its favour, and tests it against some of the most debated theories of consciousness. (shrink)

How much does stimulus input shape perception? The common-sense view is that our perceptions are representations of objects and their features and that the stimulus structures the perceptual object. The problem for this view concerns perceptual biases as responsible for distortions and the subjectivity of perceptual experience. These biases are increasingly studied as constitutive factors of brain processes in recent neuroscience. In neural network models the brain is said to cope with the plethora of sensory information by predicting stimulus (...) regularities on the basis of previous experiences. Drawing on this development, this chapter analyses perceptions as processes. Looking at olfaction as a model system, it argues for the need to abandon a stimulus-centred perspective, where smells are thought of as stable percepts, computationally linked to external objects such as odorous molecules. Perception here is presented as a measure of changing signal ratios in an environment informed by expectancy effects from top-down processes. (shrink)

Previously it was found that the Thing is both One Thing and another Thing at the same time. The Understanding rejects such a contradiction but Reason accepts what comes before it and allows the necessity in thought to proceed to its own conclusion. The attempt to maintain distinctions such as essential vs. unessential, singleness vs. universality, etc. may appeal to what is called ‘ordinary common sense,’ but it can now be seen that they are really only abstractions from the actual (...) truth that constitutes the entirety of perceptual consciousness. Those who do not have the presence of mind to rise above the being of the material of sense may proudly assert what they consider to be real and solid, while in truth it is only the play of abstractions that they deal with, so that such boasting is poorest where it fancies itself to be the richest. Rather than apprehending Truth, such an attitude sets itself against the Truth by calling it mere thought, ‘only in the mind’, etc. It is not possible for them to engage in scientific philosophy in which one result proceeds from another by rational necessity because they think that convincing by argument (holding one side against the other) is the natural process for winning Truth. But this is the definition of sophistry, directly the opposite of scientific philosophy in which Truth unveils itself by the rational necessity of its own dialectical development. In fact, Philosophy does also deal with mental entities but at the same time it recognizes thought as the pure essentiality that it is. It is the ignorance of our ‘scientific age’ that we neither appreciate, understand or even know how to comprehend the origin and nature of thought which is so fundamentally essential to human culture. Those who are the most neglectful of such knowledge are at the same time those who most vehemently propound sensuous materialism in the name of realism and seek to annul the place of thought altogether, thus sapping Truth of its own essence. Perceptual understanding holds on to mere abstract fixed essentialities without comprehending their specific determinations, i.e. it apprehends concepts as simple familiarities and therefore does not penetrate into the actual determinateness that constitutes such concepts. In that way it fails to master them; rather such abstract essentialities become the master of this understanding, constraining it to an endless bondage in opposing dualities. By holding on to only one determinateness as truth in opposition to its other and then turning to the opposite one (e.g., as we find in Kant’s antinomies) the ultimate unessentiality of both is established, yet it ignores this fact. What perceptual consciousness should do is accept the unessentiality of both sides and thereby recognize the sublimation of these opposing elements in a higher unity. Instead of doing that, however, it resorts to the in so far as and thus leads itself into abstractions and untruth. (shrink)
