John Foster presents a penetrating investigation into the question: what is it to perceive a physical object? Is perceptual contact with a physical object, he asks, something fundamental, or does it break down into further factors? If the latter, what are these factors, and how do they combine to secure the contact? For most of the book, Foster addressed these questions in the framework of a realist view of the physical world. But the arguments which thereby unfold - arguments which (...) undermine direct realism and establish a version of the sense-datum theory - lead to the conclusion that we do no perceive physical objects at all. The only way to avoid this conclusion is by abandoning physical realism for a form of idealism, and this is the option which Foster finally embraces. The Nature of Perception makes an important contrbution to the ongoing debate: it sheds fresh light on the traditional issues, and breathes new life into positions which most current philosophers assumeto be dead.

Following his earlier books The Case for Idealism and The Immaterial Self John Foster once again defends a form of idealism. For much of this book, however, idealism remains in the background. Instead, the focus is on theories of perception; Foster examines what purports to be an exhaustive taxonomy of physical realist theories of perception and, finding each one wanting, portrays idealism as the only acceptable alternative. The arguments, a selection of which are summarized below, are highly organized (...) and clearly expressed but make relatively little explicit reference to recent literature on perception. (shrink)

Hamlyn's book is exactly what the subtitle says it is: a history of the philosophy of perception, where this is taken to be a part of what is now called the philosophy of mind, as distinguished from the theory of knowledge. He expounds and criticizes, clearly and carefully, the views of Western philosophers from the pre-Socratics to Ryle and Sartre, and in a final chapter of about ten pages he offers some conclusions of his own. He holds that "in (...) the primary sense, perception can signify any means whereby we come to recognize, identify or characterize something by means of the senses" ; that there is a conceptual connection between perception and sensation, in the sense that "an essential condition of our application of the concept of perception to a being of any kind is that such a being should have sense experiences or sensations" ; but that it is a mistake "to ask what experiences, processes or activities constitute perception... [although] this is just the question which has so often been asked in the history of philosophy and psychology". "An understanding of the concepts of sensation and perception comes... not by asking what experiences, processes or activities these terms stand for. It can come only as the result of an inquiry into the concepts which form the schemes to which these particular concepts belong". These schemes, Hamlyn says, center around the concept of knowledge, and include such concepts as those of identification, recognition, and awareness. (shrink)

The process of recognition or isolation of one or several entities from among many possible entities is termed intellego perception. It is shown that not only are many of our everyday percepts of this type, but perception of microscopic events using the methods of quantum mechanics are also intellego in nature. Information theory seems to be a natural language in which to express perceptual activity of this type. It is argued that the biological organism quantifies its sensations using (...) an information theoretical measure. This, in turn, sets the stage for a mathematical theory of sensory perception.

Can philosophical theories of perception defer to perceptual science when fixing their ontological commitments regarding the objects of perception? Or in other words, can perceptual science inform us about the nature of perception? Many contemporary mainstream philosophers of perception answer affirmatively. However, in this essay I provide two arguments against this idea. On the one hand, I will argue that perceptual science is not committed to certain assumptions, relevant for determining perceptual ontology, which however are generally (...) relied upon by philosophers when interpreting such science. On the other hand, I will show how perceptual science often relies on another assumption, which I call the ‘Measuring instrument conception’ of sensory systems, which philosophers of perception should clearly reject. Given these two symmetric lines of argument, I will finally suggest that we ought to think differently about the relationship between perceptual science and the philosophy of perception. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy: the constructive nature of human perception. Many of the things that we believe are generated by our senses interacting with the outside world. Our brains make decisions about what information to interpret and how to do so mostly based on our assumptions, preconceptions, and desires. An assumption that informs how we interpret the information that our brain receives is that the size, color, and shape of objects is (...) constant. This allows us to perceive an object the same way even if how we are seeing it is changing. There are of course countless visual illusions that demonstrate this fact. This is why science has proved to be such a powerful tool in understanding the world; it is designed specifically to guard against the way our senses can lead us astray. (shrink)

It can seem puzzling that there is such a thing as the philosophy of sense-perception. Psychology and the neurosciences study the mechanisms by which our senses receive information about the environment. So conceived, perception is a psychological and physiological process, whose underlying nature will be discovered empirically. Since few philosophers these days would presume to interfere with the empirical products of these sciences, the question arises as to the nature of philosophy’s distinctive role in the study of (...) class='Hi'>perception. There is not a philosophy of digestion as there is a philosophy of perception; so what is it, exactly, that the philosophy of perception is supposed to do? (shrink)

This paper shows that direct-object perceptual verbs, such as "hear", "smell", "taste", "feel", and "see", share a collection of distinctive semantic behaviors with depictive verbs, among which are "draw'', "paint", "sketch", and "sculpt". What explains these behaviors in the case of depictives is that they are causative verbs, and have lexical decompositions that involve the creation of concrete artistic artifacts, such as pictures, paintings, and sculptures. For instance, "draw a dog" means "draw a picture of a dog", where the latter (...) occurrence of "draw" denotes a creative activity. While perceptual verbs are not obviously causatives, they have analogous decompositions involving noun phrases that denote modality-specific sense-objects, such as a sounds, smells, flavors, touches, and sights. Thus, "hear a trumpet" means "hear the sound of a trumpet", and the same holds, mutatis mutandis, for verbs denoting the other sensory modes. If we take this analogy at face value, our perceptual reports will commit us to a form of the sense-datum theory of perception. While the analogy can be resisted, resistance requires taking on unexpected commitments. (shrink)

Questions concerning perception are as old as the field of philosophy itself. Using the first-person perspective as a starting point and philosophical documents, the study examines the relationship between knowledge and perception. The problem is that of how one knows what one immediately perceives. The everyday belief that an object of perception is known to be a material object on grounds of perception is demonstrated as unreliable. It is possible that directly perceived sensible particulars are mind-internal (...) images, shapes, sounds, touches, tastes and smells. According to the appearance/reality distinction, the world of perception is the apparent realm, not the real external world. However, the distinction does not necessarily refute the existence of the external world. We have a causal connection with the external world via mind-internal particulars, and therefore we have indirect knowledge about the external world through perceptual experience. The research especially concerns the reasons for George Berkeley’s claim that material things are mind-dependent ideas that really are perceived. The necessity of a perceiver’s own qualities for perceptual experience, such as mind, consciousness, and the brain, supports the causal theory of perception. Finally, it is asked why mind-internal entities are present when perceiving an object. Perception would not directly discern material objects without the presupposition of extra entities located between a perceiver and the external world. Nevertheless, the results show that perception is not sufficient to know what a perceptual object is, and that the existence of appearances is necessary to know that the external world is being perceived. However, the impossibility of matter does not follow from Berkeley’s theory. The main result of the research is that singular knowledge claims about the external world never refer directly and immediately to the objects of the external world. A perceiver’s own qualities affect how perceptual objects appear in a perceptual situation. (shrink)

This article discusses the theories of perception of Robert Kilwardby and Peter of John Olivi. Our aim is to show how in challenging certain assumptions of medieval Aristotelian theories of perception they drew on Augustine and argued for the active nature of the soul in sense perception. For both Kilwardby and Olivi, the soul is not passive with respect to perceived objects; rather, it causes its own cognitive acts with respect to external objects and thus allows the (...) subject to perceive them. We also show that Kilwardby and Olivi differ substantially regarding where the activity of the soul is directed to and the role of the sensible species in the process, and we demonstrate that there are similarities between their ideas of intentionality and the attention of the soul towards the corporeal world.

For scatterplots with gaussian distributions of dots, the perception of Pearson correlation r can be described by two simple laws: a linear one for discrimination, and a logarithmic one for perceived magnitude (Rensink & Baldridge, 2010). The underlying perceptual mechanisms, however, remain poorly understood. To cast light on these, four different distributions of datapoints were examined. The first had 100 points with equal variance in both dimensions. Consistent with earlier results, just noticeable difference (JND) was a linear function of (...) the distance away from r = 1, and the magnitude of perceived correlation a logarithmic function of this quantity. In addition, these laws were linked, with the intercept of the JND line being the inverse of the bias in perceived magnitude. Three other conditions were also examined: a dot cloud with 25 points, a horizontal compression of the cloud, and a cloud with a uniform distribution of dots. Performance was found to be similar in all conditions. The generality and form of these laws suggest that what underlies correlation perception is not a geometric structure such as the shape of the dot cloud, but the shape of the probability distribution of the dots, likely inferred via a form of ensemble coding. It is suggested that this reflects the ability of observers to perceive the information entropy in an image, with this quantity used as a proxy for Pearson correlation. (shrink)

How do therapists learn to manage sexual feelings in the therapeutic relationship in an ethical, responsible manner? Data from 293 university-based psychotherapists show that the minority who report that their training prepared them to do so "very well" were more likely to have received "content-specific" training related to the topic or an opportunity to explore themselves as sexual beings, or both. In addition, they had experience with supervisors who modeled the belief that sexual feelings are a normal, expected part of (...) any human relationship and must be anticipated and planned for by therapists.

This essay provides an interpretation of Jonathan Edwards's moral thought that calls attention to the motif of perception in his conception of true virtue. The aim is to illumine the extent to which Edwards's virtue ethics can be included in and contribute to prevailing approaches to virtue in contemporary theological ethics. To advance this proposal, this essay attends to the question of moral agency that Edwards's reflections on charity, the new spiritual sense, and religious affections raise. This procedure offers (...) an acute sense of the significance of perception for Edwards's virtue ethics, which in turn allows for a constructive Edwardsean entry into current theological discussions on the narrative character of virtue.

This paper takes as its point of departure recent research into the possibility that human beings can perceive single photons. In order to appreciate what quantum perception may entail, we first explore several of the leading interpretations of quantum mechanics, then consider an alternative view based on the ontological phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Next, the philosophical analysis is brought into sharper focus by employing a perceptual model, the Necker cube, augmented by the topology of the Klein (...) bottle. This paves the way for addressing in greater depth the paper’s central question: Just what would it take to observe the quantum reality of the photon? In formulating an answer, we examine the nature of scientific objectivity itself, along with the paradoxical properties of light. The conclusion reached is that quantum perception requires a new kind of observation, one in which the observer of the photon adopts a concretely self-reflexive observational posture that brings her into close ontological relationship with the observed.

Jennifer Church presents a new account of perception, which shows how imagining alternative perspectives and possibilities plays a key role in creating and validating experiences of self-evident objectivity. She explores the nature of moral perception and aesthetic perception, and argues that perception can be both literal and substantive.

In exploring the nature of psychological explanation, this book looks at how psychologists theorize about the human ability to calculate, to speak a language and the like. It shows how good theorizing explains or tries to explain such abilities as perception and cognition. It recasts the familiar explanations of "intelligence" and "cognitive capacity" as put forward by philosophers such as Fodor, Dennett, and others in terms of a theory of explanation that makes established doctrine more intelligible to professionals and (...) their students.In particular, the book shows that vestigial adherence to the positivists' D-N model has distorted the view of philosophers of science about what psychologists (and biologists) do and has masked the real nature of explanation. Major sections in the book cover Analysis and Subsumption; Functional Analysis; Understanding Cognitive Capacities; and Historical Reflections.Robert Cummins is Associate Professor of Philosophy at the University of Illinois, Chicago Circle.

Theory-ladenness of perception and cognition is pervasive and variable. Emerging maturationally natural perception and cognition, which are on-line, fast, automatic, unconscious, and, by virtue of their selectivity, theoretical in import, if not in form, define normal development. They contrast with off-line, slow, deliberate, conscious perceptual and cognitive judgments that reflective theories, including scientific ones, inform. Although culture tunes MN systems, their emergence and operation do not rely on culturally distinctive inputs. The sciences advance radically counter-intuitive representations that depart (...) drastically from MN systems’ deliverances. Extensive experience with RCI scientific theories can result in a practiced naturalness with their perceptual and cognitive consequences; nevertheless, automatic MN verdicts persistently intrude. Fodor suggests that the uniformity of the biases MN systems introduce can serve as a theory-neutral means for adjudicating scientific disputes. Findings about vision challenge Fodor’s proposal for circumventing problems that MN theory-ladenness presents. These considerations indicate that RCI scientific ideas are difficult to learn, master, and deploy; consequently, the corrective import of science’s social and institutional arrangements plays a critical role in its epistemic stature.

The 500th anniversary of theReformation, which is celebrated in Ukraine at the state level, gives an opportunity to evaluate this event in various dimensions of its foundation, development and transformation in the context of the European transition from feudal relations and their citadel - the Catholic Church to the establishment of protestantism as an innovation faith and ideologiy of a new social formation. The process of the spread of early protestantism in Ukraine an its perception by the Ukrainian mentality (...) and modern functionality in independent Ukraine are researched. (shrink)

The author defends the naturalizing program of the notion of representation against the primitivist view according to which the notion of representation as belonging to psychology as a mature science is irreducible. First, the author concedes that the original teleological project trivializes the concept of representation by applying it to bacteria, protozoa, amoeba, when the best available explanation is the assumption that primitive organisms and artifacts are merely indicating proximal stimulation rather than representing the distal causes of stimulation. Yet, the (...) author does not believe that this presents an unsurmountable obstacle for the naturalizing program when what is in question is genuine sensory representation, namely perception. In the author’s view, what matters for the naturalizing program are not cases in which the concept of representation is misemployed, but rather cases in which the focus is genuine sensory representation, that is, genuine perceptions; or so he shall argue.

Perceptual constancies have been studied by psychologists for decades, but in recent years, they have also become a major topic in the philosophy of mind. One reason for this surge of interest is Tyler Burge’s (2010) influential claim that constancy mechanisms mark the difference between perception and mere sensitivity, and thereby also the difference between organisms with genuine representational capacities and ‘mindless’ beings. Burge’s claim has been the subject of intense debate. It is becoming increasingly clear, however, that we (...) cannot hope to settle this debate (as well as related debates in the philosophy of mind) without a clear and substantive theoretical account of what perceptual constancies are. In the first part of this paper, I argue that the standard definitions in the literature fall short of providing such an account. Still, as I aim to show in the second part of the paper, by taking a closer look at some of the paradigm examples, it is possible to construct a plausible general account of perceptual constancies that is both clear and substantive, and that can serve as a firm foundation for settling debates like the dispute about Burge’s ‘constancy mechanism criterion’ for perception.

From the outside, our senses are spatially integrated in our body in manifestly different ways. This paper starts from the suggestion that the philosophical formulation of the problem of spatial perception, as it flows from the modern opposition of mind and world, is partly responsible for the fact that philosophers have often explicitly disregarded the spatial nature of the senses themselves. An indirect consequence is that much philosophical work focuses on how the senses can – or cannot – perceive (...) the same spatial features of objects in the same way, while disregarding the massive differences in performance among the senses. This paper explores the ways in which the spatial integration of our senses determines what each of our senses excels in, and hence what they contribute to our spatial relation to a physical environment. By juxtaposing descriptive analyses of a variety of selected cases, the paper gives priority to how various aspects of the world appear to us in order to obtain insight into the meaning of spatiality for different senses.

For Reid, sensations do not enter into the analysis of perception proper. Instead they “intervene” between the effects of bodily qualities on our sense organs and our perception of those qualities (Inq VI xxi, 174).1 The question addressed in this essay is: What sort of thing does Reid take this interloper to be?2 The answer defended is that sensations are reflexive mental acts, i.e., acts which take themselves as objects.

Le réductionnisme scientiste a privé le monde de ce qui avait été un univers enchanté, empli des formes et des esprits qui hantaient le monde médiéval. Merleau-Ponty et Husserl dans son œuvre tardive tentent de réenchanter la nature, mais du point de vue de la perception. Leur insistance sur la structure et la forme perceptuelles est un moyen de protection contre le réductionnisme et donc, en un sens, réenchante le monde qui, pour parler comme Merleau-Ponty, est « con­damné au (...) sens ». Être « con­damné au sens », cela signifie être forcé de reconnaître à nos réalisations rationnelles les plus abouties, à nos actes visant à relier ce qui est séparé à partir d’une relationalité déjà perçue, une dépendance génétique (ou Fundierung ) par rapport à des événements de niveau inférieur, pré-rationnels, dans lesquels le soi est présent de façon latente. Être « con­damné au sens » signifie que les réalisations logiques et rationnelles pleinement articulées doivent, pour être dotées de sens, être ramenées à des structures proto-rationnelles dans le champ de la perception. Que Merleau-Ponty et Husserl révèlent la sphère pré-prédicative comme une sphère de simple signification, ce fait reflète une critique commune de l’empirisme. Le monde partiellement réenchanté est un monde conditionné par des horizons de signification qui sont de réels aspects du monde à décrire. Je fais valoir que la perception optimalement monstrative atteint les choses mêmes dans leur télos monstratif où elles se montrent le mieux. Je conclus avec quelques remarques sur la manière dont cette conception du réenchantement mobilise la philosophie de John McDowell, qui est, malgré lui, un partisan de la structure dans le champ perceptuel.

The nature of perception has long been a central question in philosophy. It is of crucial importance not just in the philosophy of mind, but also in epistemology, metaphysics, aesthetics, and the philosophy of science. The essays in this 1992 volume not only offer fresh answers to some of the traditional problems of perception, but also examine the subject in light of contemporary research on mental content. A substantial introduction locates the essays within the recent history of the (...) subject, and demonstrates the links between them. The Contents of Experience brings together some prominent philosophers in the field, and offers a major statement on a problem central to current philosophical thinking. Notable contributors include Christopher Peacocke, Brian O'Shaughnessy and Michael Tye. (shrink)

The aim of this special issue of Rivista di Estetica is to investigate the nature of the auditory object and its specific status as an object of perception. The investigation was carried out using different methodologies: 1) focusing on the auditory object in relation to its metaphysical dimension; 2) working on the comparison between auditory and visual perception; 3) finding similarities and differences between auditory and musical objects; and, finally, 4) focusing exclusively on the speci...

This chapter considers how Liberal Naturalism interacts with the main problems and theories in the philosophy of perception. After briefly summarising the traditional philosophical problems of perception and outlining the standard philosophical theories of perceptual experience, it discusses whether a Liberal Naturalist outlook should incline one towards or away from any of these standard theories. Particular attention is paid to the work of John McDowell and Hilary Putnam, two of the most prominent Liberal Naturalists, whose work was also (...) very influential in the philosophy of perception. There is also a section focusing on colour, an especially important topic not only for debates about perceptual experience but also for debates concerning how our ‘manifest image’ of the natural world relates to our best theories in the physical sciences.
