Philosophy of Perception, General

Defenders of moral perception have famously argued that seeing value is relevantly similar to seeing color. Some critics think, however, that the analogy between color-seeing and value-seeing breaks down in several crucial respects. Defenders of moral perception, these critics say, have not succeeded in providing examples of non-moral perception that are relevantly analogous to cases of moral perception. Therefore, it can be doubted whether there is such a thing as moral perception at all. I argue that, although the analogy between (...) color perception and moral perception does indeed break down in several crucial respects, that conclusion does not weaken the case of defenders of moral perception, because better analogies are available. If defenders of moral perception seek to draw support from an analogy, then seeing emotion will protect them better against criticisms than will seeing color. (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.

This chapter argues that the only tenable unconscious inferences theories of cognitive achievement are ones that employ a theory internal technical notion of representation, but that once we give cash-value definitions of the relevant notions of representation and inference, there is little left of the ordinary notion of representation. We suggest that the real value of talk of unconscious inferences lies in (a) their heuristic utility in helping us to make fruitful predictions, such as about illusions, and (b) their providing (...) a high-level description of the functional organization of subpersonal faculties that makes clear how they equip an agent to navigate its environment and pursue its goals.

Como tantas vezes na filosofia, o título não só estabelece a linha de batalha, mas expõe os preconceitos e erros do autor, pois se podemos ou não entender o jogo de linguagem 'Ver as coisas como elas são' e se é possível ter uma "teoria filosófica" de percepção" (que é Pode ser sobre como a linguagem da percepção funciona), ao contrário de uma científica, que é uma teoria sobre como o cérebro funciona, são exatamente os problemas. Este é o Searle (...) Classic, excelente e provavelmente pelo menos tão bom quanto qualquer um pode produzir, mas sem uma compreensão completa das ideias fundamentais do Wittgenstein posterior e sem entender os dois sistemas-quadro de pensamento, que poderia ter feito brilhante. Como em seu trabalho anterior, Searle evita em grande parte a ciência, mas há lapsos frequentes e não entende que problemas são sempre sobre jogos de idiomas, uma falha que ele compartilha com quase todos. Depois de fornecer uma estrutura composta por uma Mesa de Intencionalidade baseada nos dois sistemas de pensamento e pensamento e pesquisa de decisões, faço uma análise detalhada do livro. Aqueles que querem uma estrutura completa até o momento para o comportamento humano do ponto de vista moderno de dois sistemas podem consultar meus livros Talking Monkeys 3rd ed (2019), Estrutura Lógica da Filosofia, Psicologia, Mente e Linguagem em Ludwig Wittgenstein e John Searle 2ª ed (2019), Suicide Pela Democracy 4ª ed (2019), The Logical Structure of Human Behavior (2019), The Logical Structure of Consciousness (2019, Understanding the Connections Between Science, Philosophy, Psychology, Religion, Politics and Economics (2020) e Illusions Utopias Suicidas no Século 21 6ª ed (2020), Observações sobre Impossibilidade, Incompletude, Paraconsistência, Indecidabilidade, Aleatoriedade, Computação, Paradoxo e Incerteza em Chaitin, Wittgenstein, Hofstadter, Wolpert, Doria, da Costa, Godel, Searle, Rodych Berto, Floyd, Moyal-Sharrock e Yanofsky (2019) e outros.

An ongoing philosophical discussion concerns how various types of mental states fall within broad representational genera—for example, whether perceptual states are “iconic” or “sentential,” “analog” or “digital,” and so on. Here, I examine the grounds for making much more specific claims about how mental states are structured from constituent parts. For example, the state I am in when I perceive the shape of a mountain ridge may have as constituent parts my representations of the shapes of each peak and saddle (...) of the ridge. More specific structural claims of this sort are a guide to how mental states fall within broader representational kinds. Moreover, these claims have significant implications of their own about semantic, functional, and epistemic features of our mental lives. But what are the conditions on a mental state's having one type of constituent structure rather than another? Drawing on explanatory strategies in vision science, I argue that, other things being equal, the constituent structure of a mental state determines what I call its distributional properties—namely, how mental states of that type can, cannot, or must co‐occur with other mental states in a given system. Distributional properties depend critically on and are informative about the underlying structures of mental states, they abstract in important ways from aspects of how mental states are processed, and they can yield significant insights into the variegation of psychological capacities.

This chapter has four parts. I distinguishes some types of perceptual skills and highlights their importance in everyday perception. II identifies a well-studied class of perceptual skills: cases of perceptual expertise. III discusses a less studied possible instance of perceptual skill: picture perception. Finally, IV outlines some important mechanisms underlying perceptual skills, with special emphasis on attention and mental imagery.

How does an audience receive a work of art? Does the experience only affect the viewer or does it have an effect and thus influence his or her actions? It is the cultural philosopher Ernst Cassirer and his successors in philosophy and developmental psychology as well as in neuroscience to this day who postulate that perception in general and perception of art in particular are not neutral in their origins but alive and thus meaningful. They assume that both are based (...) on analogous principles: in the perception of moving forms and spatial forms in the world and rhythms of forms, colors, light and shadow in art. In practice, this means that perception and its felt effects have an effect on the feelings of the viewer and thus help him to inform himself directly and intensively about the world through art. In contrast to this general epistemological aesthetic theory, which philosophers in particular accept, it is to be shown that this assumption must be redefined not with reference to the world, but with reference to art and design. For the latter, the approach will be extended to a semiotic theory. The background is that in contrast to the world, the designed forms and thus the designed intentions of the artist and designer or his client in relation to the chosen theme have an impact on the viewer and thus on culture and its communicative dynamics.

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

The paper argues that the reconciliation of the Causal Theory of Perception with Disjunctivism requires the rejection of causal particularism – the idea that the ontology of causation is always and everywhere an ontology of particulars (e.g., events). The so-called ‘Humean Principle’ that causes must be distinct from their effects is argued to be a genuine barrier to any purported reconciliation, provided causal particularism is retained; but extensive arguments are provided for the rejection of causal particularism. It is then explained (...) how the reconciliation of the causal theory with disjunctivism can proceed on the basis of an ontology of facts. (shrink)

Philosophers and psychologists often assume that mirror reflections are optical illusions. According to many authors, what we see in a mirror appears to be behind it. I discuss two strategies to resist this piece of dogma. As I will show, the conviction that mirror reflections are illusions is rooted in a confused conception of the relations between location, direction, and visibility. This conception is unacceptable to those who take seriously the way in which mirrors contribute to our experience of the (...) world. My argument may be read as an advertisement of the neglected field of philosophical catoptrics, the philosophical study of the optical properties of mirrors. It enables us to recast familiar issues in the philosophy of perception. (shrink)

ABSTRACTIneffability of musical meaning is a frequent theme in music philosophy. However, talk about musical meaning persists and seems to be not only inherently enjoyable and socially acceptable, but also functionally useful. Relying on a phenomenological account of musical meaning combined with a naturalist explanatory attitude, we argue for a novel explanation of how ineffability is a feature of musical meaning and experience and we show why it cannot be remedied by perfecting language or musico-philosophical study.Musical meaning is seen as (...) an experiential phenomenon that consists of layers, some recent, others archaic. As such, musical meaning is strongly characterized by asubjectivity. It is in-between, in a state where the division of subject and object is not yet valid or valid anymore. A naturalistic interplay of experiential layers in music brings about a non-reified dynamics driving for expressions, interpretations, engenderings of subjects and objects or even for political action. Generally speaking, the in-betweenness of musical meaning can never be universally reified or symbolic nor can it ever be “subjective,” “mine” or present “at the origin.”In this view, ineffability has two primary reasons. First, the criteria offered for defining musical meaning are often too strict, resulting in untenable pretensions of universality. Second, the processual and relational nature of the in-between keeps meaning in flux; any snapshot creates a new situation and new meanings. (shrink)

In this paper, I put forward an argument for the view that emotional responses of esteem to perceived demonstrations of good character represent the perceived character traits as valuable, and hence, as virtues. These esteeming experiences are analogous to perceptual representations in other modalities in their epistemic role as causing, providing content for and justifying beliefs regarding the value of the traits they represent. I also discuss the role that the perceiver’s own character plays in their ability to recognize and (...) respond appropriately to virtue in others, showing that moral virtues are also epistemic virtues when it comes to facilitating knowledge about the character of people we encounter. (shrink)

A perceptual realism that is naive in a good way must be naively realistic about world and mind. But contemporary self-described naive realists often have trouble acknowledging that both the good cases of successful perception and the bad cases of illusion and hallucination involve internal experiential states with intentional contents that present the world as being a certain way. They prefer to think about experience solely in relational terms because they worry that otherwise we won’t be able to escape from (...) radical skepticism. I argue that experiential relations to objects require that their subjects be in internal experiential states. But this does not mean that these states are our epistemological starting point which can be known independently of any knowledge of the external world. We do escape the epistemological predicament of radical skepticism because the good cases are primary over the bad ones. But this is not because the good cases alone provide reasons for belief, but because we do not need a reason to think we are in a good case, but do need a reason to think we are not, and such a reason must come from a good case. So bad cases can only be thought of as deviations from good cases. And we can only understand experiences as states with contents distinct from their objects and present in good and bad cases once we understand misrepresentation, that is, bad cases, and therefore only as we ascribe knowledge of the external world to ourselves.

I offer some responses to Prosser’s ‘Experiencing Time’, one of whose goals is to debunk a view of temporal experience somewhat prevalent in the metaphysics literature, which I call ‘Perceptualism’. According to Perceptualism: it is part of the content of perceptual experience that time passes in a metaphysically strong sense: the present has a metaphysically privileged status, and time passes in virtue of changes in which events this ‘objective present’ highlights, and moreover this gives us evidence in favor of strong (...) passage. Prosser argues that perception cannot be sensitive to whether the strong passage obtains, and therefore cannot represent strong passage in a way that gives us evidence of its truth. Although I accept this conclusion, I argue that Prosser’s argument for it is problematic. It threatens to over-generalize to rule out uncontroversial cases of perceptual knowledge, such as our knowledge that we live in a spatial world. Furthermore, a successful argument ruling out perceptual evidence for strong passage would have to give constraints on the theory/observation distinction of a kind not provided by Prosser’s discussion. I also comment on several other parts of the book. (shrink)

In this paper I claim that perceptual discriminatory skills rely on a suitable type of environment as an enabling condition for their exercise. This is because of the constitutive connection between environment and perceptual discriminatory skills, inasmuch as such connection is construed from an ecological approach. The exercise of a discriminatory skill yields knowledge of affordances of objects, properties, or events in the surrounding environment. This is practical knowledge in the first-person perspective. An organism learns to perceive an object by (...) becoming sensitized to its affordances. I call this position ecological disjunctivism. A corollary of this position is that a case of perception and its corresponding case of hallucination—which is similar to the former only in some respects—are different in nature. I show then how the distinguishability problem is addressed by ecological disjunctivism. (shrink)

In this paper, I develop and defend a new adverbial theory of perception. I first present a semantics for direct-object perceptual reports that treats their object positions as supplying adverbial modifiers, and I show how this semantics definitively solves the many-property problem for adverbialism. My solution is distinctive in that it articulates adverbialism from within a well-established formal semantic framework and ties adverbialism to a plausible semantics for perceptual reports in English. I then go on to present adverbialism as a (...) theory of the metaphysics of perception. The metaphysics I develop treats adverbial perception as a directed activity: it is an activity with success conditions. When perception is successful, the agent bears a relation to a concrete particular, but perception need not be successful; this allows perception to be fundamentally non-relational. The result is a novel formulation of adverbialism that eliminates the need for representational contents, but also treats successful and unsuccessful perceptual events as having a fundamental common factor.

According to a certain kind of naïve or folk understanding of physical matter, everyday ‘solid’ objects are composed of a homogeneous, gap-less substance, with sharply defined boundaries, which wholly fills the space they occupy. A further claim is that our perceptual experience of the environment represents or indicates that the objects around us conform to this sort of conception of physical matter. Were this further claim correct, it would mean that the way that the world appears to us in experience (...) conflicts with the deliverances of our best current scientific theories in the following respect: perceptual experience would be intrinsically misleading concerning the structure of physical matter. I argue against this further claim. Experience in itself is not committed to, nor does it provide evidence for, any such conception of the nature of physical matter. The naïve/folk conception of matter in question cannot simply be ‘read-off’ from perceptual appearances. (shrink)

Review of Searl's book Seeing Things as They are.

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

The claim currently known as “disjunctivism” is usually interpreted in terms of exclusive disjunction. However, it can be also explicated through the lens of alternative denial. The aim of this paper is to show that the latter interpretation is more accurate. Firstly, it reflects the core of disjunctivism more precisely. Secondly, it reduces metaphysical weight of the claim, thereby making it more plausible.

This thesis is about experiential content: what it is; what kind of account can be given of it. I am concerned with identifying and attacking one main view - I call it the inferentialist proposal. This account is central to the philosophy of mind, epistemology and philosophy of science and perception. I claim, however, that it needs to be recast into something far more subtle and enriched, and I attempt to provide a better alternative in these pages. The inferentialist proposal (...) holds that experiential content is necessarily under¬pinned by sophisticated cognitive influences. My alternative, the continuum theory, holds that these influences are relevant to experience only at certain levels of organisation and that at other levels there are contents which such features do not capture at all. Central to my account is that there are degrees to which cognitive influences affect experiential content; indeed, for the most part, experience is an amalgam of both inferential and non-inferential features. I claim that the inferentialist proposal is fundamentally flawed and deserves replacement, and I argue that my alternative fills the hollow that remains. The thesis is divided into four sections. In Part I, Chapter 1, I introduce two traditionally rival views of experiential content. In Chapter 2, I develop my continuum alternative. Chapter 3 assesses the relationship between experience and language, while Chapter 4 explores the relationship between beliefs and experience. The overall argument is that it has been a mistake to understand experience simply in inferential or non-inferential terms. In Part II, I examine the structure of mental content. Chapter 5 is concerned with the kinds of experiences which escape the inferentialist analysis. Chapter 6 considers Kant’s metaphysic of experience counterpointed to Lorenz’s reading of his work in the light of evolutionary biology. Chapter 7 treats animal experience in relation to the continuum view I am developing, while Chapter 8 reviews Fodor’s contribution to perceptual psychology. It is argued that the view of experiential content being developed is both consistent with empirical data on informationally local perceptual sub-systems, but also accords well with evolutionary theory and a naturalist interpretation of Kant’s taxonomy. Part III deals with inferentialism in the philosophy of science. In Chapter 9, I assess the theory dependence of observation thesis as it is advanced by Paul Feyerabend. I bring out of his account a subtle confusion concerning the importance of inference in the context of scientific inquiry. Part IV deals with the issue of experience in the philosophy of mind. In Chapter 10, I look at Wilfred Sellars’s attack on sense data theories. Chapter 11 confronts Paul Churchland’s treatment of ‘folk psychology’ while Chapter 12 isolates the issue of experiential qualia and the position of property dualism. I offer a critical review of Thomas Nagel’s work in this chapter and claim that his position can be read in a way which is consistent with the continuum account I am developing. I conclude the thesis in the usual fashion with a summary of the central claims. (shrink)

This paper proposes a methodological strategy to investigate the question of the individuation of the senses both from a commonsensical and a scientific point of view. We start by discussing some traditional and recent criteria for distinguishing the senses and argue that none of them taken in isolation seems to be able to handle both points of views. We then pay close attention to the faculty of hearing which offers promising examples of the strategy we pursue of combining commonsense and (...) science. In particular, we argue in favour of a distinction between two kinds of modes of presentation associated with sound perception: a mechanical mode of presentation that makes sounds perceptible by other modalities than audition such as touch and a tonal mode of presentation that makes people conceive of sounds as the proper objects of auditory perception.

The Whorfian hypothesis has received support from recent findings in psychology, linguistics, and anthropology. This evidence has been interpreted as supporting the view that language modulates all stages of perception and cognition, in accordance with Whorf’s original proposal. In light of a much broader body of evidence on time perception, I propose to evaluate these findings with respect to their scope. When assessed collectively, the entire body of evidence on time perception shows that the Whorfian hypothesis has a limited scope (...) and that it does not affect early stages of time perception. In particular, all the available evidence shows that the scope of language modulation is limited in the case of time perception, and that the most important mechanisms for time perception are cognitive clocks and simultaneity windows, which we use to perceive the temporal properties of events. Language modulation has distorting effects, but only at later stages of processing or with respect to specific categorization tasks. The paper explains what is the role of these effects in the context of all the available evidence on time cognition and perception. (shrink)

In this paper, I have outlined an original Metaphysics of Perception which takes into consideration some of the most common views about perception in the contemporary debate. Then I will look at the consequences of this metaphysics about our perception of others and what we know about them.

In the conclusion, I recap what has been done to say that others (...) are what we can know after all. (shrink)

As so often in philosophy, the title not only lays down the battle line but exposes the author’s biases and mistakes, since whether or not we can make sense of the language game ‘Seeing things as they are’ and whether it’s possible to have a ‘philosophical’ ‘theory of perception’ (which can only be about how the language of perception works), as opposed to a scientific one, which is a theory about how the brain works, are exactly the issues. This is (...) classic Searle—superb and probably at least as good as anyone else can produce, but lacking a full understanding of the fundamental insights of the later Wittgenstein and with no grasp of the two systems of thought framework, which could have made it brilliant. As in his previous work, Searle largely avoids scientism but there are frequent lapses and he does not grasp that the issues are always about language games, a failing he shares with nearly everyone. After providing a framework consisting of a Table of Intentionality based on the two systems of thought and thinking and decision research, I give a detailed analysis of the book. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

Despite extensive discussion of naïve realism in the wider philosophical literature, those influenced by the phenomenological movement who work in the philosophy of perception have hardly weighed in on the matter. It is thus interesting to discover that Edmund Husserl’s close philosophical interlocutor and friend, the early twentieth-century phenomenologist Johannes Daubert, held the naive realist view. This article presents Daubert’s views on the fundamental nature of perceptual experience and shows how they differ radically from those of Husserl’s. The author argues, (...) in conclusion, that Daubert’s views are superior to those of Husserl’s specifically in the way that they deal with the phenomenon of perceptual constancy. (shrink)

Proponents of enactivism should be interested in exploring what notion of action best captures the type of action-perception link that the view proposes, such that it covers all the aspects in which our doings constitute and are constituted by our perceiving. This article proposes and defends the thesis that the notion of sensorimotor dependencies is insufficient to account for the reality of human perception, and that the central enactive notion should be that of perceptual practices. Sensorimotor enactivism is insufficient because (...) it has no traction on socially dependent perceptions, which are essential to the role and significance of perception in our lives. Since the social dimension is a central desideratum in a theory of human perception, enactivism needs a notion that accounts for such an aspect. This article sketches the main features of the Wittgenstein-inspired notion of perceptual practices as the central notion to understand perception. Perception, I claim, is properly understood as woven into a type of social practices that includes food, dance, dress, music, etc. More specifically, perceptual practices are the enactment of culturally structured, normatively rich techniques of commerce of meaningful multi- and inter-modal perceptible material. I argue that perceptual practices explain three central features of socially dependent perception: attentional focus, aspects’ saliency, and modal-specific harmony-like relations. (shrink)

Drawing on Merleau-Ponty’s “Eye and Mind” and Bergson’s Matière et mémoire and “La perception du changement,” I ask what resources are available in vision for interrupting objectifying habits of seeing. While both Bergson and Merleau-Ponty locate the possibility of seeing differently in the figure of the painter, I develop by means of their texts, and in dialogue with Iris Marion Young’s work, a more general phenomenology of hesitation that grounds what I am calling “critical-ethical vision.” Hesitation, I argue, stems from (...) affect and leads to critical memory. In hesitation, the seeming coincidence between my habits of seeing and the visible is decentered, revealing these habits and their social reference as the constitutive horizon of my field of vision. Hesitation, then, provides the phenomenological moment within which vision may become at once critically watchful, destabilizing its objectifying habits, and ethically responsive, recollecting its affective grounds. The critical and the ethical are here inseparable. Critically, this vision is an awareness of the structures of invisibility, diacritical and habitual, social and historical, to which my vision owes—dimensions which institute particular ways of seeing and being as norm while eliding others. Ethically, this is the recognition of how seeing is already seeing with others—others whose affective influence is operative within vision, even as their existence is reductively represented or denied.

Do we perceptually experience moral properties like rightness and wrongness? For example, as in Gilbert Harman’s classic case, when we see a group of young hoodlums pour gasoline on a cat and ignite it, can we, in the same robust sense, see the action’s wrongness?. Many philosophers have recently discussed this question, argued for a positive answer and/or discussed its epistemological implications. This paper presents a new case for a negative answer by, first, getting much clearer on how such experience (...) could be possible at all; second, responding the only argument for a positive answer; and, finally, arguing that postulation of such experience is explanatorily redundant.

It seems possible to see a star that no longer exists. Yet it also seems right to say that what no longer exists cannot be seen. We therefore face a puzzle, the traditional answer to which involves abandoning naïve realism in favour of a sense datum view. In this article, however, I offer a novel exploration of the puzzle within a naïve realist framework. As will emerge, the best option for naïve realists is to embrace an eternalist view of time, (...) and claim that in the relevant case, one sees a still existent star‐stage located somewhere in the distant past.

This paper sets out a novel response to the ‘screening off problem’ for naïve realism. The aim is to resist the claim (which many naïve realists accept) that the kind of experience involved in hallucinating also occurs during perception, by arguing that there are causal constraints that must be met if an hallucinatory experience is to occur that are never met in perceptual cases. Notably, given this response, it turns out that, contra current orthodoxy, naïve realists need not adopt any (...) particular view about the psychological nature of hallucinatory experience to handle the screening off problem. Consequently, room opens up for naïve realists to endorse whatever theory of hallucinatory experience seems to best capture the distinctive nature of such episodes. (shrink)

In this paper, I present the enactive theory of color that implies a form of color relationism. I argue that this view constitutes a better alternative to color subjectivism and color objectivism. I liken the enactive view to Husserl’s phenomenology of perception, arguing that both deconstruct the clear duality of subject and object, which is at the basis of the other theories of color, in order to claim the co-constitution of subject and object in the process of experience. I also (...) extend the enactive and phenomenological account of color to the more general topic of the epistemological and ontological status of sensory qualities (qualia), outlining the fields of enactive phenomenology and enactive ontology.

Review of Duncan Pritchard's Epistemological Disjunctivism.

What is the distinctively philosophical problem of perception? Here it is argued that it is the conflict between the nature of perceptual experience as it intuitively seems to us, and certain possibilities which are implicit in the very idea of experience: possibilities of illusion and to the world' which involves direct awareness of existing objects and their properties. But if one can have an experience of the same kind without the object being there -- a hallucination of an object -- (...) then it seems that perceptual experience cannot essentially be such a relation. This is the fundamentally philosophical problem of perception; the various philosophical theories of perception in the 20th and 21st centuries can be seen as responses to it. (shrink)

The topic of this paper is the perception of properties. It is argued that the perception of properties allows for a distinction between the sense of the identity and the sense of the qualitative nature of a property. So, for example, we might perceive a property as being identical over time even though it is presented as more and more determinate. Thus, you might see an object first as red and then as crimson red. In this case, the property is (...) perceived as identical over time, even though the sense of the qualitative nature (the redness, the crimson redness) of the property is changing. The distinction between the sense of identity and the sense of quality is explicated in terms of perceiving a particular property, a trope, and perceiving it as an instance of a universal. It is subsequently argued that the perceived tropes cannot constitute the phenomenal character of the perceptual experience. (shrink)

Western science claims to provide unique, objective information about the world. This is supported by the observation that peoples across cultures will agree upon a common description of the physical world. Further, the use of scientific instruments and mathematics is claimed to enable the objectification of science. In this work, carried out by reviewing the scientific literature, the above claims are disputed systematically by evaluating the definition of physical reality and the scientific method, showing that empiricism relies ultimately upon the (...) human senses for the evaluation of scientific theories and that measuring instruments cannot replace the human sensory system. Nativist and constructivist theories of human sensory development are reviewed, and it is shown that nativist claims of core conceptual knowledge cannot be supported by the findings in the literature, which shows that perception does not simply arise from a process of maturation. Instead, sensory function requires a long process of learning through interactions with the environment. To more rigorously define physical reality and systematically evaluate the stability of perception, and thus the basis of empiricism, the development of the method of dimension analysis is reviewed. It is shown that this methodology, relied upon for the mathematical analysis of physical quantities, is itself based upon empiricism, and that all of physical reality can be described in terms of the three fundamental dimensions of mass, length and time. Hereafter the sensory modalities that inform us about these three dimensions are systematically evaluated. The following careful analysis of neuronal plasticity in these modalities shows that all the relevant senses acquire from the environment the capacity to apprehend physical reality. It is concluded that physical reality is acquired rather than given innately, and leads to the position that science cannot provide unique results. Rather, those it can provide are sufficient for a particular environmental setting. (shrink)

In his initial lecture course at the Collège de France, Merleau-Ponty attempted to develop a new analysis of rational thought in order to clarify its link with corporeal-perceptive life. The formulation of thought in language as the most elaborate human activity of expression explicitly takes over what we already observe in perception as the implicit and mutual reference between the perceiving subject and that which is perceived.The article reconstructs Merleau-Ponty’s argumentation, based on his preparatory notes for the lectures, and provides (...) an interpretation of the key concepts of “expression” and “body schema”.

There are two related points at which J.J. Gibson’s ecological theory of visual perception remains remarkably underspecified: Firstly, the notion of information for perception is not explicated in much detail beyond the claim that it “specifies” the environment for perception, and, thus being an objective affair, enables an organism to perceive action possibilities or “affordances.” Secondly, misperceptions of affordances and perceptual illusions are not clearly distinguished from each other. Although the first claim seems to suggest that any perceptual illusion amounts (...) to the misperception of affordances, there might be some relevant differences between various ways of getting things wrong. In this essay, Gibson’s notion of “specifying” information shall be reconstructed along the lines of Fred Dretske’s relational theory of information. This refined notion of information for perception will then be used to carve out the distinction between perceptual illusions and the misperception of affordances, with some help from the “Empirical Strategy” (developed by Purves et al.). It will be maintained that there are cases where perceptual illusions actually help an organism to correctly perceive an affordance. In such cases, the prima facie misrendered informational relations involved are kept intact by a set of appropriate transformation rules. Two of Gibson’s intuitions shall thus be preserved: the objectivity of informational relations and the empowerment of the organism as an active perceiver who uses those objective relations to his specific ends.

The question of whether perception can be penetrated by cognition is in the limelight again. The reason this question keeps coming up is that there is so much at stake: Is it possible to have theory-neutral observation? Is it possible to study perception without recourse to expectations, context, and beliefs? What are the boundaries between perception, memory, and inference (and do they even exist)? Are findings from neuroscience that paint a picture of perception as an inherently bidirectional and interactive process (...) relevant for understanding the relationship between cognition and perception? We have assembled a group of philosophers and psychologists who have been considering the thesis of cognitive (im)penetrability in light of these questions (Abdel Rahman & Sommer, 2008; Goldstone, Landy, & Brunel, 2011; Lupyan, Thompson-Schill, & Swingley, 2010; Macpherson, 2012; Stokes, 2011). Rather than rehashing previous arguments which appear, in retrospect, to have been somewhat ill-posed (Pylyshyn, 1999), this symposium will present a thesis of cognitive (im)penetrability that is at once philosophically satisfying, empirically testable, and relevant to the questions that cognitive scientists find most interesting.

Naive realism is a widely debated topic in the philosophy of the mind. In this article I will review the theses of naive realism through the works of one of the most influential philosophers who supported and developed them, Michael Martin. Once the reasons why naive realism should be supported are discussed, I will propose an empirical argument to show that naive realism and the most basic scientific knowledge of perceptive processes are contradictory.

You can perceive things, in many respects, as they really are. For example, you can correctly see a coin as circular from most angles. Nonetheless, your perception of the world is perspectival. The coin looks different when slanted than when head-on, and there is some respect in which the slanted coin looks similar to a head-on ellipse. Many hold that perception is perspectival because you perceive certain properties that correspond to the “looks” of things. I argue that this view is (...) misguided. I consider the two standard versions of this view. What I call the PLURALIST APPROACH fails to give a unified account of the perspectival character of perception, while what I call the PERSPECTIVAL PROPERTIES APPROACH violates central commitments of contemporary psychology. I propose instead that perception is perspectival because of the way perceptual states are structured from their parts. (shrink)

A natural starting point for theories of perceptual states is ordinary perception, in which a subject is successfully related to her mind-independent surroundings. Correspondingly, the simplest theory of perceptual states models all such states on perception. Typically, this simple, common-factor relational view of perceptual states has received a perfunctory dismissal on the grounds that hallucinations are nonperceptual. But I argue that the nonperceptual view of hallucinations has been accepted too quickly. I consider three observations thought to support the view, and (...) argue that all three are dealt with equally well by an alternative view, illusionism, on which hallucinations do involve perception. Since this is so, adopting a common-factor relational view of all perceptual states remains a tenable option. (shrink)
