The Nature of Perceptual Experience

Since the transparency approach to introspection need not posit a dedicated mechanism specialized for detecting one’s own mental states, its economy is often viewed as a major advantage by both proponents and opponents. But sometimes economy comes at the cost of relying on controversial views of the natures of mental states. Perceptual experience is a case in point. For example, Alex Byrne’s account relies on the view that experience constitutively involves belief, and Matthew Boyle’s account relies on the view that (...) experience constitutively involves a form of implicit consciousness of experience. In this paper, I develop a transparency account of our access to our experiences that retains the benefit of economy while avoiding the cost of relying on controversial views of the nature of experience. I start by discussing Byrne’s and Boyle’s accounts. I focus on the problems that lead them to hold the controversial views they do, and raise some challenges to their solutions. I then develop my own account. I argue that when you attend to an object, your experience gives you justification to believe that you see the object (under some descriptions). I close by highlighting some advantages of my account. I argue that it (1) can solve the problems facing Byrne and Boyle without relying on controversial views of the nature of experience; (2) respects the idea that there is something special about our access to our minds; and (3) can be generalized to other cases of introspection.

Perceptual Confidence is the thesis that perceptual experiences can be probabilistic. This thesis has been defended and criticised based on a variety of phenomenological, epistemological, and explanatory arguments. One gap in these arguments is that they neglect the question of whether perceptual experiences satisfy the formal conditions that define the notion of probability to which Perceptual Confidence is committed. Here, we focus on this underexplored question and argue that perceptual experiences do not satisfy such conditions. But if they do not, (...) then ascriptions of perceptual confidence are undefined; and so, Perceptual Confidence cannot be true. (shrink)

In this commentary on Neil Mehta's excellent book, A Pluralist Theory of Perception, I argue that Mehta's commitments lead to dualism. To this end, I give three arguments against physicalism that centrally rely on claims Mehta accepts. Since the relevant claims are highly plausible, the three arguments give everyone, not just Mehta, reason to reject physicalism.

What is active touch? A common conception of active touch gives a rough but rather intuitive sketch. That is, active touch can be understood as mainly object-oriented, controlled movement. While parts or the totality of this characterization is espoused by an important number of researchers on touch, I will argue that this conception faces important challenges when we pay close attention to each of these features. I hold that active touch should be considered as before all else purposive. This view (...) has its roots in the active sensing literature in robotics but will be amended to give insight into human touch in the natural world. (shrink)

There has been a long-standing debate in philosophy and psychology about the role of representation in visual perception. Here, we argue on the basis of evidence from philosophy, psychology, and neuroscience that episodic and schematic memory representations are pivotal to the visual perception of objects and scenes. In the visual perception of objects and scenes, sensory information is initially matched with object and scene templates, or schemas, in long-term memory. The most relevant representations are then selected for encoding in working (...) memory. We furthermore argue that activations of episodic memory representations contribute to the fineness of grain of visual representations. The representational view of visual perception that emerges is what we call the "template tuning view." According to this view, prior information – specifically, long-term memories – shape the representational content of visual perception. In the final section of the chapter, we argue that unlike representational conceptions of visual perception, naïve and direct realist theories have difficulties accommodating these findings.

What is perception? What is, if any, its content? What is the contribution of perception to knowledge? This book addresses these questions clearly and directly. The chief thesis the author argues for is that perception has conceptual, propositional, and world-dependent content. After criticizing those theories of experience that conceive it as contentless (the causal-linkage approach and naïve realism), the book examines the nature of perceptual content. Here, the author critically scrutinizes different varieties of non-conceptualism and claims that the content of (...) experience is partly conceptual. Having established that thesis, the author defends the propositional-attitude view, according to which perceptual content is propositional in nature. A crucial step in the book comes when the author explores the world-dependent character of such content. He holds here that the content of experience is composed of concepts and the presented objects, such as they appear from the subject’s point of view and determined environmental conditions. This view allows him to state that perception provides non-inferential knowledge of the truth-makers of our judgments and beliefs. Furthermore, and importantly, that view sheds light on how the mind relates to the world. (shrink)

From the very beginning, phenomenology met with sound inquiry. Not only the relationship between Husserl and Stumpf, whose investigations influenced numerous philosophers and twenty-century trends, but a whole musicological thread (Mersmann, Eimert, Güldenstein, Bekker) referred to phenomenology during the twenties and following decades (Besseler, Leibowitz, Schaeffer, Rognoni). From another side, explicit aesthetic reflections are traceable in the Göttingen Circle but also in W. Conrad, Schütz, Plessner, and Anders-Stern. Even Heidegger, Merleau-Ponty, up to Smith, Ihde, Dufrenne, Clifton, Ferrara, and Piana, which (...) more or less systematically dealt with sound. The aim of this work is to show the fundamental cores of a phenomenology of sound; then, the continuing need for research. Through themes like the constitution of the sound-object, the phenomenological distinction between sounds and noises, and the spatial features of sound, the phenomenological scenario of sound inquiry will be pointed out and analyzed.

Perception, as the most fundamental process in cognition, serves as the foundation for human understanding and cognition of the external world and the self. In recent years, emerging artificial perception technologies have surpassed human sensory limitations, expanding human cognition of the world and the self. This transition from natural perception to artificial perception poses new challenges to human cognition. Artificial perception technology not only mimics human sensory capabilities but also transcends traditional modes of perception, possessing distinct characteristics from natural senses. (...) By integrating artificial technology with human brain interaction, artificial perception creates a novel form of human perception. However, a unilateral enhancement of human perception through artificial means may not necessarily achieve cognitive enhancement; instead, it may disrupt and interfere with innate human natural perception and existing logical reasoning.

It is first shown that many questions could be raised about phenomenal concepts and the popular answer to the question what Mary learns upon release, namely, that this is what it is like to see red. It is then shown that the category of quale is actually a postulate of philosophical theories and philosophers posit qualia because they fail to see how to account for the two related features of experience, namely, subjectivity and phenomenality. It is argued that we don't (...) need qualia to explain the subjectivity and phenomenality of experience because we don't have to posit apparent properties. It is then proposed that experiencing is a way of knowing and that the new knowledge Mary acquires upon release is her knowledge by acquaintance with red. (shrink)

It is widely thought that there are limits to how things can perceptually appear to us. For instance, nothing can appear both square and circular, or both pure red and pure blue. Adam Pautz has dubbed such constraints “laws of appearance.” But if the laws of appearance obtain, then what explains them? Here I examine the prospects for an empirical explanation of the laws of appearance. First, I challenge extant empirical explanations that appeal purely to the format of perceptual representation. (...) I then develop a hybrid approach, on which the laws are explained not merely by format, but by two further factors: ecological constraints imposed by our environments, and computational constraints embodied by our perceptual systems. While the hybrid approach implies that the laws of appearance are contingent, I argue that this implication is empirically defensible, since even some of the most intuitively compelling laws have real-world counterexamples.

[Open Access.] Perceptual experiences have presentational phenomenology: we seem to encounter real situations in the course of visual experiences, for instance. The current paper articulates and defends the claim that the contents of at least some perceptual experiences are inherently presentational. On this view, perceptual contents are not always forceless in the way that, say, the propositional content that 2 + 2 = 4 is generally taken to be, as a content that may be asserted or denied or merely supposed; (...) rather, there are perceptual contents such that any mental state or episode which has the relevant content must be one in which things seem to the given subject to be a certain way. Intuitive motivation for the view is presented and an explanatory line of argument in support of it is developed: it is argued that the recognition of inherently presentational perceptual contents allows us to explain certain representational limitations to which ordinary visualizations and other forms of perceptual mental imagery are subject. Some potential objections to the position are explored, leading to further elaboration of it. (shrink)

___MERGING of temporally distant events: One perceives a singular causal relation that c causes e whenever c instantiates a mental property C which anticipates a certain mental property E instantiated by e.

How can we have a sense of the presence of ordinary three-dimensional objects (e.g., an apple on my desk, a partially occluded cat behind a picket fence) when we are only presented with some parts of objects perceived from a particular egocentric viewpoint (e.g., the facing side of the apple, the unoccluded parts of the cat)? This paper presents and defends a novel answer to this question by incorporating insights from two prominent contemporary theories of perception, naïve realism and sensorimotor (...) theory. Naïve realism is the view that perception is fundamentally a matter of obtaining a relation of ‘acquaintance’ with some mind-independent entities (e.g., objects, properties, events). Sensorimotor theory holds that perception involves implicit practical understanding or ‘anticipation’ of the covariance between movements and sensory changes. I argue that perceptual presence is best accounted for in terms of the combination of our direct ‘acquaintance’ with some parts of perceived objects and sensorimotor ‘anticipations’ of how the objects would look different depending on some movements and actions.

In the philosophical literature, it is customary to think of perception as being assessable with respect to epistemic norms. E.g., the whole discussion around disjunctivism, which is now often considered to be the dominant, if not the default position in philosophy of perception, is, by and large, framed and motivated by epistemological concerns about truth and falsity. This book argues that perception is normative in another, more fundamental sense. Perception is governed by norms that Doyon calls perceptual, that is, immanent (...) to its own structure. This does not mean that perceptual norms are cut-off from external facts; it rather means that they are constitutive moments of our experience of these facts. Perceptual norms are, in that sense, constitutive or enabling norms in that they establish what perception is. To articulate this view, he draws in the repertoire of the phenomenological tradition, in the work of Edmund Husserl and Maurice Merleau-Ponty in particular. Like Kant, both phenomenologists were concerned with the question of the unity of experience and sought to identify the conditions of possibility for having a perception, which they conceive not as a mere sensible experience of the outer world, but as a continuous and meaningful experience of reality. Unlike Kant, however, neither phenomenologist immediately identified these conditions with cognition or epistemic criteria. For both phenomenologists, perception has its own standards, its own conditions of possibility. Perception obtains when it unfolds concordantly or coherently; and when the perceptual progression corresponds to or is in harmony with one's goal or interest, perception can also be said to be optimal. From the phenomenological point of view, concordance (Einstimmigkeit) and optimality (Optimalität) are the two basic perceptual norms governing over perceptual experience, and much of the book is devoted to clarifying their meaning and to address the philosophical consequences that follow from this insight.

In this short paper, I outline four philosophical arguments concerning the objects we perceive. These arguments build up to the conclusion that the objects of perceptual experience are material objects. I then show that the first three of these arguments parallel important psychological positions in vision science. Thus, (1) the notion of object used in Logical Atomism resembles the concept as it is defined in the Feature Integration Theory of Treisman and Gelade (1980). But (2) Frank Jackson's (1975) Many-Property Problem (...) leads to a substrate-quality structure for visual experience that corresponds to the structure of attended experience in Feature Integration Theory. A third philosophical argument (3) concerns the perception of movement. This argument culminates in the proposition that perceptual features are seen as belonging to material objects. There is a close resemblance between these objects and those of Zenon Pylyshyn's (1980) FINSTs. Finally, (4) I argue that material objects are the only substrates of multimodal perceptual experience. Perceptual psychology has yet to investigate this structure. (shrink)

In several of his works, Immanuel Kant insists on the transcendental role of imagination in perception. In the Kantian scholarship, this claim has been interpreted in at least three ways: it is believed that the imagination is necessary to solve the riddle of the amodal character of perception, to justify the possibility of perceptual identity across time, and to explain the possibility of perceiving particular objects as such, viz. as belonging to a specific class of objects. The paper aims to (...) show how E. Husserl inherited these sets problems without however having recourse to the imagination at all. In the last section, I will briefly analyse two types of mixed acts where perception and imagination unite, namely image consciousness (Bildbewusstsein) and what Husserl calls perceptual phantasy (perzeptive Phantasie). I here argue that these analyses do not contradict, but rather strengthen the argument defended throughout the paper, namely that in Husserl's phenomenology, and contrary to Kant's, the imagination does not assume a synthetic or transcendental function in perception.

Menschen sind häufig nicht ganz bei der Sache. Oft finden wir sie abwesend, nicht ganz da, sich in Tagträume verlierend, in Gedanken schon bei der nächsten Sache; finden sie irgendwie nicht ganz hinein in die Situationen, mit denen sie sich gerade konfrontiert finden. Der Beitrag entwickelt die These, dass die Rede von der "Immersivität" von Erfahrung nicht erst bei technologisch oder ästhetisch mediierten Erlebnissen des Versetztseins in künstliche oder virtuelle "Welten" und Umgebungen am Platz, gewöhnliche menschliche Erfahrung vielmehr ganz grundsätzlich (...) durch eine immersive Dynamik des Hineinfindens in und Hinausgeratens aus Situationen charakterisiert ist: Noch bevor wir uns ein bewusstes Bild konkreter Umstände und Möglichkeiten gemacht haben, finden wir uns gewöhnlich schon in Situationen verortet. Diese zeichnen bestimmte Rhythmen und Richtungen, Valenzen und Tendenzen, Bedeutsamkeiten und Möglichkeiten vor. Der Beitrag skizziert eine Phänomenologie der Immersion, die auch ein tieferes Verständnis technologisch oder ästhetisch mediierter Immersionserfahrungen verspricht. (shrink)

Der Aufsatz untersucht, inwiefern der Sprache in der Phänomenologie die Rolle zukommt, das Individuum deiktisch in den Situationen seiner Existenz zu orientieren, indem sie kategorial auf Gegebenheiten seiner Erfahrung zeigt. Phänomenologisches Philosophieren geht in dieser Hinsicht über das bloße, innertheoretische Geben und Nehmen von Gründen sowie die Absicherung objektiver Wissensbestände (zu denen es gleichfalls nicht in Opposition tritt) hinaus, und zielt dabei evokativ auf orientierende Erkenntniseffekte im Subjekt. Statt als innersprachliche "Deskriptionen" oder Bezeichnungen von Phänomenen fungieren phänomenologische Begriffe und Beschreibungen (...) als verbale Zeigegesten, die dem Individuum im erfolgreichen Fall die bezeigten (und in diesem Sinne "be-deuteten") Phänomene selbst vor Augen führen.

When we watch movies, or are tricked by a trompe-l'oeil painting, we seem to be visually representing possible worlds; often non-actual possible worlds. This suggests that we really can visually represent possible worlds. The suggested claim is refined and developed here into a theory of visual experience that holds that all visual experiences, both veridical and non-veridical, represent possible worlds, many of which are non-actual.

With what modes of mentality can we build a visceral, subjective sense of being in some specific mass-political society? Theorists and political cultivators standardly call upon the imagination – the kind prompted by symbols and rituals, for example. Could perception ever play such a role? I argue that it can, but that perceptions of mass-political publics come with costs of cruelty and illusion that neither democratic theorists nor participants should be willing to pay. The clearest examples of such perceptions are (...) found in fascist political culture. My discussion aims to illuminate what it is about publics, perception, and democracy that makes this so. -/- .

Intentionalism is the view that perceptual phenomenology depends on perceptual content. The aim of this paper is to make explicit an ambiguity in usual formulations of intentionalism, and to argue in favor of one way to disambiguate it. It concerns whether perceptual phenomenology depends on the content of one and only one representation (often construed as being identical to a certain perceptual experience), or instead depends on a collection of many different representations throughout the perceptual system. We argue in favor (...) of the latter option. Intentionalism so conceived can make better sense of contemporary neuroscience of perception, and is better equipped to confront several influential objections to traditional intentionalism.

The notion of hyle seems problematic for a phenomenological foundation of experience. For this very reason, its completed invalidity was generally postulated. At the same time, there are many reflections in Husserlian writings that help us understand it better. This paper attempts to show how hyletic experience, by existing in the lived body, triggers in parallel rhythmic, vibrating, and sonorous experiences as bodily experiences. Sounds are experienced by the body before any reflections or conscious experiences of them. In this way, (...) the aporetical instance of hyletic data founds a proposal of resolution in the fundamental corporeal experience of sound. (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)

Perceptual experience supports the assignment of confidences in belief – doxastic confidences. To explain this fact, many philosophers appeal to Perceptual Indeterminacy, which holds that perceptual content can be more or less determinate. Others instead appeal to Perceptual Confidence, which says that perceptual experience supports doxastic confidences because it assigns confidences too. Morrison argues that a primary reason to favour Perceptual Confidence is that it is uniquely capable of accounting for bell-shaped doxastic confidence distributions; we call this the bell curve (...) objection to Perceptual Indeterminacy. Here we show that two recent defences of Perceptual Indeterminacy, due to Nanay and Raleigh and Vindrola, fail to adequately address the bell curve objection. But we also argue that all is not lost for proponents of Perceptual Indeterminacy. They can counter the bell curve objection by embracing a third view, which we call Perceptual Noise. (shrink)

The purpose of this article is to offer a new view of the key relation between the content and the conscious character of visual experience. The author aims to support the following claims. First, the author rejects the qualia realist claim that conscious character is an intrinsic, nonrepresentational property of visual experience, for example, a pattern of activation of neurons. However, the author also rejects the rival widespread representationalist claim that the conscious character of visual experience is identical to, or (...) supervenes on, any specific property represented by visual experience. The positive proposal is the following. Conscious character is identical to those patterns of activation of neurons that are referentially or representationally alive. Conscious redness, for example, is a pattern of activations of neurons that is normally created only when brains of physical duplicates come in visual contact with some distal property. This pattern of activation is recruited by natural selection to represent that property. This is called meaning representationalism. (shrink)

This article presents a dual purpose: to carefully consider objections against the existentialist conception of the content of visual experience and to develop and defend a version of it that avoids such objections, specifically addressing the so-called "problem of particularity." The main thesis is that the existential content of visual experience should be understood as relativized, being incomplete content (rather than classical, complete propositions), modeled as a function of the sextuple of the object, agent, time, place, causal relation, and world (...) to absolute values.

This volume takes cue from the idea that the thought of no philosopher can be understood without considering it as the result of a constant, lively dialogue with other thinkers, both in its internal evolution as well as in its reception, re-use, and assumption as a starting point in addressing past and present philosophical problems. In doing so, it focuses on a feature that is crucially emerging in the historiography of early modern philosophy and science, namely the complexity in the (...) production of knowledge. The book explores the applicability of this approach to a long-considered armchair philosopher, namely René Descartes, who is now more and more understood as a full-blown scientist, networker, and intellectual éminence grise rather than as the mere philosopher of the cogito, as well as the originator of different ‘Cartesianisms’ which encompassed many ideas and approaches for long captured by dichotomic historiographical categories as rationalism and empiricism, or speculative and experimental philosophy. The essays gathered in the volume aim to address the ways in which Descartes’s philosophy evolved and was progressively understood by scientists, philosophers, and intellectuals from different contexts and eras, either by considering direct interlocutors of Descartes such as Isaac Beeckman and Elisabeth of Bohemia, early modern thinkers who developed upon his ideas and on particular topics as Nicolas Malebranche or Thomas Willis, those who adapted his overall methodology in developing new systems of knowledge as Johannes Clauberg and Pierre-Sylvain Régis, and contemporary thinkers from continental and analytic traditions like Emanuele Severino and Peter Strawson.

In recent work, Scott Soames (2010, 2013, 2015, 2019) and Peter Hanks (2011, 2013, 2015) have developed a theory of propositions on which these are constituted by complexes of intellectual acts. In this article, I adapt this type of theory to provide an account of perceptual content. After introducing terminology in section 1, I detail the approach proffered by Soames and Hanks in section 2, focusing on Hanks’s version. In section 3, I introduce a problem that these theories face, namely, (...) how to account for the unity among the relevant intellectual acts. Section 4 provides an answer to this problem of unity, while section 5 explicates the relation to Soames and Hanks. In section 6, I extend the model to a theory of the unity of experiential consciousness. Finally, in section 7, I apply the preceding considerations to debates about the nature of perceptual representation. The upshot will be that experiential unity is not simply a phenomenal feature of consciousness, but central to an account of the role perceptual representation plays in perceptual cognition.

The argument from appearance for the content view or intentionalism attracts a lot of attention recently. In my paper, I follow Charles Travis to argue against the key premise that representational content can be ‘read off’ from a certain way that a thing looks to a subject. My arguments are built upon Travis’s original objection and a reinterpretation of Rodrick Chisholm’s comparative and noncomparative uses of appearance words. Byrne, Schellenberg and others interpret Travis’ ‘visual looks’ as Chisholm’s comparative use, and (...) appeal to the noncomparative use as an alternative to avoid Travis’s objection. I demonstrate that they misunderstand both Chisholm and Travis. Both the comparative use and the noncomparative use are semantic notions, while ‘visual looks’ is a metaphysical one. Although Chisholm’s appearance objectivism –– that appearance expressions attribute appearances to ordinary objects –– is close to ‘visual looks’, appearance objectivism is not exceptional to the noncomparative use as Byrne interprets. In the end, I also show that Byrnean’s conception of distinctive visual gestalt cannot exclude contrary representational contents, because a distinctive visual gestalt can be shared by different kinds of things. Besides, Byrne and others do not explain why a distinctive visual gestalt should be presented as ‘being instantiated’. Therefore, I conclude that representational content cannot be read off from a certain way that a thing looks to a subject; the argument from appearance thus fails. (shrink)

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.

How many factors, i.e. departures from normality, are necessary to explain a delusion? Maher’s classic one-factor theory argues that the only factor is the patient’s anomalous experience, and a delusion arises as a normal explanation of this experience. The more recent two-factor theory, on the other hand, contends that a second factor is also needed, with reasoning abnormality being a potential candidate, and a delusion arises as an abnormal explanation of the anomalous experience. In the past few years, although there (...) has been an increasing number of scholars offering a variety of arguments in defence of Maher’s one-factor theory, these arguments have not been adequately addressed by two-factor theorists. This paper aims to address this gap by critically examining the arguments on three crucial issues: the intelligibility of delusions, the dissociation between anomalous experiences and delusions, and the empirical evidence of a second factor. I will argue that the Maherian notion of anomalous experience is not sufficient for explaining delusions and the two-factor theory is on the right track in its search for the missing factor in the aetiology of delusions.

Extended reality devices provide users with unprecedented immersive and hybrid perceptual experiences, and users will act their bodies according to the information perceived. This shows that visual perception plays a crucial role in the formation and shaping of self-perception and spatial position. Users have a strong perceptual experience of their physical presence and self-perception in the real world as a result of their avatar perspective based on visual perception in a virtual hybrid environment, as is issued by Chalmers in his (...) "Mirror Argument". However, users can still clearly differentiate their self and spatial experience between virtual and reality. To refute Chalmers' argument regarding perceptual experience in virtual reality, this article proposes a thought experiment called "Mary's Room in the Virtual Reality World" based on the experimental evidence of neuroscience. Finally, a possible future solution to this dilemma is presented. (shrink)

Em seu exame da teoria da verdade cartesiana, Raul Landim (1993, 2009) enuncia as três questões que toda teoria da verdade deve responder: (a) o sentido de ‘verdade’; (b) a possibilidade de conhecimentos verdadeiros e (c) a possibilidade do reconhecimento de conhecimentos verdadeiros. Os argumentos a serem apresentados dizem respeito sobretudo à terceira questão, mas consideram a necessidade de ser assegurar uma resposta adequada à segunda questão. Para tanto, retomarei (I) brevemente alguns pontos de um artigo anterior sobre o tema (...) (2017) para, em seguida, dar prosseguimento ao estudo ali iniciado, que ainda deverá ser completado em um terceiro texto, sobre atenção, representação e intecionalidade. Com efeito, três contextos argumentativos são relevantes para o exame da noção de atenção: (i) o tratamento psicofísico da atenção; (ii) as condições para a busca da verdade, no qual a atenção designa, prima facie, uma modulação do pensar, que é relevante para o método; (iii) a explicação do caráter intencional do pensar humano, no qual a atenção é um aspecto do pensar concernente à seleção do conteúdo pensado no tempo presente (presença). Somente o segundo será considerado aqui. Após a retomada dos resultados anteriores, apresentarei indícios da relação entre a atenção e o conceito de intenção na história da filosofia que precede Descartes e, em seguida, farei uma breve análise das ocorrências do texto na obra cartesiana (II). Por fim, na seção (III), passarei à análise daquelas ocorrências ligadas ao método do filósofo, tanto no que se refere à sua intervenção na determinação do critério de reconhecimento da verdade (a regra geral da verdade, ou regra do claro e do distinto), quanto no esclarecimento da via analítica do método de demonstração geométrico.

Several important philosophical problems (including the problems of perception, free will, and scepticism) arise from antinomies that are developed through philosophical paradoxes. The critical strand of ordinary language philosophy (OLP), as practiced by J.L. Austin, provides an approach to such ‘antinomic problems’ that proceeds from an examination of ‘ordinary language’ (how people ordinarily talk about the phenomenon of interest) and ‘common sense’ (what they commonly think about it), and deploys findings to show that the problems at issue are artefacts of (...) fallacious reasoning. The approach is capable, and in need of, empirical development. Proceeding from a case-study on Austin’s paradigmatic treatment of the problem of perception, this paper identifies the key empirical assumptions informing the approach, assesses them in the light of empirical findings about default inferences, contextualisation failures, and belief fragmentation, and explores how these findings can be deployed to address the problem of perception. This facilitates a novel resolution of the problem of perception. Proceeding from this paradigm, the paper proposes ‘experimental critical OLP’ as a new research program in experimental philosophy that avoids apparent non-sequiturs of OLP, extends and transforms experimental philosophy’s ‘sources program’, and provides a promising new strategy for deploying empirical findings about how people ordinarily talk and think about phenomena, to address longstanding philosophical problems.

Sensory Individuals: Unimodal and Multimodal Perspectives provides an interdisciplinary, well-balanced, and comprehensive look at different aspects of unisensory and multisensory objects, using both nuanced philosophical analysis and informed empirical work. The research presented in this book represents the field's progression from treating neural sensory processes as primarily modality-specific towards its current state of the art, according to which perception, and its supporting neural processes, are multi-modal, modality-independent, meta-modal, and task-dependent. Even within such approaches sensory stimuli, properties, brain activations, and corresponding (...) perceptual phenomenology can still be characterized in a modality-specific way. The book examines the basic building blocks of human perception, and whether they are best understood as sense modality dependent units of different forms or multimodal perceptual objects. The book combines a variety of innovative and integrative angles to explore the topic and acts as a catalyst for an increasingly diverse field of research, which is in an exciting phase of growth and advancement. New questions are arising as quickly as they are being answered, and the collection Sensory Individuals provides an original and up-to-date addition to the field. (shrink)

The kind of empathy that is communicated through expressions like “I feel your pain” or “I share your sadness” is important, but peculiar. For it seems to require something perplexing and elusive: sharing another’s experience. It’s not clear how this is possible. We each experience the world from our own point of view, which no one else occupies. It’s also unclear exactly why it is so important that we share others' pains. If you are in pain, then why should it (...) matter, and be a good thing, that I am also in the same pain? Our goal in this paper is to address these questions. Specifically, our goal is to clarify how empathy, in the regimented sense of sharing another’s pain, is possible and why it is important. Central to our account is the concept of being acquainted with—that is, directly aware of—pain. When I feel my own pain, and am acquainted with it, I want the pain to stop, and I’m moved—sometimes compelled—to stop it. My acquaintance with the pain is what reveals that it is no good, to be gotten rid of, and to be avoided in the future. Acquaintance also appears to be implicated in our understanding of, and motivation to relieve, others’ pains. When I say “I feel your pain” I express an awareness of your pain, a direct appreciation of its noxious qualities, and, as with my own pain, an understanding of why it ought to be eased. Explaining how empathy is both possible and important therefore involves clarifying the nature of acquaintance: its limits, epistemic role, and motivational significance. What our analysis reveals is that agents have both epistemic and moral reasons to share other people’s pain because pain-sharing is the source of a species of character-building knowledge that we have no other way of accessing except through direct acquaintance with pain.

ABSTRACT The difference between perception and cognition seems introspectively obvious in many cases. Perceiving and thinking have also been assigned quite different roles, in epistemology, in theories of reference and of mental content, in philosophy of psychology, and elsewhere. Yet what is the nature of the distinction? In what way, or ways, do perception and cognition differ? The paper reviews recent work on these questions. Four main respects in which perception and cognition have been held to differ are discussed. First, (...) their phenomenal character, such as the often-remarked vivacity or immediacy of perception. Second, the way in which they represent the world, e.g. the non-propositional nature of the contents, or non-discursive character of the vehicles, that have been held to characterise perceptual representation. Third, their place in cognitive architecture, i.e., roughly, in the information-flow of the mind, such as their alleged (non-)modularity. Fourth, their mind-world relations, e.g. the way in which perceptions seem to be tightly causally linked with distal or proximal stimuli. Against this background, we distinguish some main options for an account of the perception/cognition distinction, in particular concerning whether there is one, several, or no interesting and principled distinction(s) to be drawn here.

This paper identifies three positions on the relationship between language and experience, the third of which I was not acquainted with before from my reading. It seems absurd.

When I see some object, it visually seems as if the location of that object is distinct from the location from which it is perceived. For example, if I hold out my pencil in front of me, it visually seems to be at some location there, but I seem to it see it from some other location here. The place from which one perceives is, of course, occupied by one's body, and in this chapter I consider whether, in order to (...) capture sight's spatial perspectival character, we need to accept that in normal visual experience, one’s body is always perceptually represented, even though it is typically outside of the visual field (call this the ‘visual bodily awareness claim’, or VBA). I argue that we don’t need to accept VBA, and in particular, that a promising-seeming argument for the claim that we do, fails. Instead, I suggest, aspects of phenomenal character that might lead us to accept VBA can be explained by appeal to structural features of visual experience. (shrink)

Perception can’t have disjunctive content. Whereas you can think that a box is blue or red, you can’t see a box as being blue or red. Based on this fact, I develop a new problem for the ambitious predictive processing theory, on which the brain is a machine for minimizing prediction error, which approximately implements Bayesian inference. I describe a simple case of updating a disjunctive belief given perceptual experience of one of the disjuncts, in which Bayesian inference and predictive (...) coding pull in opposite directions, with the former implying that one’s confidence in the belief should increase, and the latter implying that it should decrease. Thus, predictive coding fails to approximately implement Bayesian inference across the interface between belief and perception. (shrink)

A central claim in contemporary philosophy of mind is that the phenomenal character of experience is entirely determined by its content. This paper considers an alternative called Mode Intentionalism. According to this view, phenomenal character outruns content because the intentional mode contributes to the phenomenal character of the experience. I assess a phenomenal contrast argument in support of this view, arguing that the cases appealed to allow for interpretations which do not require positing intentional modes as phenomenologically manifest aspects of (...) experience.

This paper analyzes the objections of Adolf Reinach to Kant’s transcendental apriorism, shedding light on (1) the speculative distance separating their conceptions of philosophy (namely Reinach’s phenomenology and Kant’s transcendental critique), and (2) the consequential misunderstanding which is at the core of Reinach’s confrontation with Kant. In particular, attention is paid to the issue of the transcendental constitution of objectness, i.e. the question of the givenness of an object with respect to certain functions proper to the subject. In order to (...) illustrate how such a concept is completely absent in Reinach, I will compare his position with those of Husserl, in their relations with Kant’s interpretation of Hume’s philosophy.

Some have defended a Fregean view of perceptual content. On this view, the constituents of perceptual contents are Fregean modes of presentation (MOPs). In this paper, I propose that perceptual MOPs are best understood in terms of object files. Object files are episodic representations that store perceptual information about objects. This information is updated when sensory conditions change. On the proposed view, when a subject perceptually represents some object a under two distinct MOPs, then the subject initiates two object files (...) that both refer to a. My defense of this view appeals to its satisfaction of four constraints that I argue theories of perceptual MOPs should satisfy. Furthermore, I show that some existent accounts of perceptual MOPs fail to satisfy them. The defended constraints also indicate what is unique about perceptual, as opposed to linguistic or cognitive, MOPs. (shrink)
