George Berkeley's linguistic account of sense perception is one of the most central tenets of his philosophy. It is intended as a solution to a wide range of critical issues in both metaphysics and theology. However, it is not clear from Berkeley's writings just how this ‘universal language of the Author of Nature’ is to be interpreted. This paper discusses the nature of the theory of sense perception as language, together with its metaphysical and (...) theological motivations, then proceeds to develop an account of the semantics of the perceptual language, using Berkeley's theory of reference for human language as a guide.

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.

John Foster addresses the question: what is it to perceive a physical object? He rejects the view that we perceive such objects directly, and argues for a new version of the traditional empiricist account, which locates the immediate objects of perception in the mind. But this account seems to imply that we do not perceive physical objects at all. Foster offers a surprising solution, which involves embracing an idealist view of the physical world.

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 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 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.

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)

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)

Making sense of the world around us is a process involving both semiotic and material mediation—the use of signs and sign systems and various kinds of tools. As we use them, we experience them subjectively as extensions of our bodily selves and objectively as instruments for accessing the world with which we interact. Emphasizing this bipolar nature of language and technics, understood as intertwined "forms of sense," Robert Innis studies the multiple ways in which they are rooted (...) in and transform human perceptual structures in both their individual and social dimensions. The book foregrounds and is organized around the notion of "semiotic embodiment." Language and technics are viewed as "probes" upon which we rely, in which we are embodied, and that themselves embody and structure our primary modes of encountering the world. While making an important substantive contribution to present debates about the "biasing" of perception by language and technics, Innis also seeks to provide a methodological model of how complementary analytical resources from American pragmatist and various European traditions can be deployed fruitfully in the pursuit of new insights into the phenomenon of meaning-making.

In lieu of an abstract, here is a brief excerpt of the content:150 PERCEPTIONS, OBJECTS AND THE NATURE OF MIND In this paper I consider the relation between perceptions and objects for Hume and the bearing which this has on his conception of the mind as composed of perceptions. But first it is necessary to distinguish at least two senses in which he uses the term 'object'. In the first, "perceptions of the human mind" — both impressions and ideas (...) — are referred to as "our objects" (T 1,2). Objects in this sense are intentional objects. Hume almost consistently uses the noun 'perception', rarely the verb 'to perceive'. This serves to emphasize that for him perception is an object, not the perceiving of an object — a departure from the tradition of Locke and Berkeley for whom perceptions are cognitive acts having objects. That perception is not conceived by Hume as a cognitive act or form of awareness but purely as an object of awareness is evident when he says, For since all actions and sensations of the mind are known to us by consciousness, they must necessarily appear in every particular what they are, and be what they appear. Everything that enters the mind, being in reality a perception, 'tis impossible anything shou'd to feeling appear different. This were to suppose, that even when we are most intimately conscious, we might be mistaken (T 190). 1 Or again, "The only existences, of which we are certain, are perceptions, which being immediately present to us by consciousness, command our strongest assent...." (T 212). In its other sense the term 'object' is used to denote bodies, or that to which we attribute a continued existence "distinct from the mind and perception", or, borrowing Locke's expression "external 151 objects". It is just because we attribute a continued and independent existence to bodies that we distinguish them from perceptions, for "all impressions are internal and perishing existences, and appear as such" (T 194). But while we make this distinction in our everyday role of common man, the difference between a perception and an (external) object is really only a difference between two types of perceptions, on the one hand those that are characterized in their occurrence by constancy and coherence, and on the other those, for example the passions, which exhibit a different type of "regularity" in their occurrence (T 195). The constancy and coherence which some perceptions exhibit, together with a natural tendency of the mind "to bestow on the objects a greater regularity than what is observ'd in our mere perceptions" (T 197) causes us to attribute to these perceptions an uninterrupted and independent existence, an existence which is, of course, fictitious, because all perceptions are really internal and perishing. 'Tis certain, that almost all mankind, and even philosophers themselves, for the greatest part of their lives, take their perceptions to be their only objects, and suppose, that the very being, which is intimately present to the mind, is the real body or material existence (T 206). This is not to say, however, that "what any common man means by a hat, or shoe, or stone" (T 202) he also believes to be a perception. What he does believe is that the hat or the shoe is immediately present to the mind, or directly appears to his consciousness. It is Hume, the philosopher, who is here interposing the philosophical doctrine that "no beings are ever present to the mind but perceptions" (T 212). This is, of course, not an empirical generalization. It is the definition of a perception as "whatever can be present 152 to the mind" (Abstract 647). It is this definition which gives sense to the statement "their perceptions are their only objects", the term "objects" here referring to "external objects". And the common man would, no doubt, be surprised to learn that these hats, shoes, etc., which directly appear to his consciousness, are by that circumstance really only his own perceptions which he has imagined, falsely, to have a continued and independent existence. Only a few experiments, however, are needed for the philosopher to realize that perceptions, i.e., what is present to the mind, do not have a continued and independent existence.

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.

Seeing, Doing, and Knowing is an original and comprehensive philosophical treatment of sense perception as it is currently investigated by cognitive neuroscientists. Its central theme is the task-oriented specialization of sensory systems across the biological domain. Sensory systems are automatic sorting machines; they engage in a process of classification. Human vision sorts and orders external objects in terms of a specialized, proprietary scheme of categories - colours, shapes, speeds and directions of movement, etc. This 'Sensory Classification Thesis' implies (...) that sensation is not a naturally caused image from which an organism must infer the state of the world beyond; it is more like an internal communication, a signal concerning the state of the world issued by a sensory system, in accordance with internal conventions, for the use of an organism's other systems. This is why sensory states are both easily understood and persuasive.Sensory classification schemes are purpose-built to serve the knowledge-gathering and pragmatic needs of particular types of organisms. They are specialized: a bee or a bird does not see exactly what a human does. The Sensory Classification Thesis helps clarify this specialization in perceptual content and supports a new form of realism about the deliverances of sensation: 'Pluralistic Realism' is based on the idea that sensory systems coevolve with an organism's other systems; they are not simply moulded to the external world. The last part of the book deals with reference in vision. Cognitive scientists now believe that vision guides the limbs by means of a subsystem that links up with the objects of physical manipulation in ways that bypass sensory categories. In a novel extension of this theory, Matthen argues that 'motion-guiding vision' is integrated with sensory classification in conscious vision. This accounts for the quasi-demonstrative form of visual states: 'This particular object is red', and so on. He uses this idea to cast new light on the nature of perceptual objects, pictorial representation, and the visual representation of space. (shrink)

Research on meditation and mindfulness practice has flourished in recent years. While much of this research has focused on well-being outcomes associated with mindfulness practice, less research has focused on how perception of self may change as a result of mindfulness practice, or whether these changes in self-perception may be mechanisms of mindfulness in action. This is somewhat surprising given that mindfulness derives from traditions often described as guiding people to realise and experience the non-separation of self from (...) the world or its ‘oneness’ with the whole of reality. The current study used a collective intelligence methodology, Interactive Management (IM), to explore the nature of oneness experiences. Five IM sessions were conducted with five separate groups of experienced meditators. Participants generated, clarified, and selected oneness self-perceptions they believed most characterised their experience both during meditation and in their everyday experience in the world. Each group also developed structural models describing how highly ranked aspects of oneness self-perceptions are interrelated in a system. Consistent themes and categories of oneness experience appeared across the five IM sessions, with changes in the sense of space (unboundedness), time, identity, wholeness and flow highlighted as most influential. Results are discussed in light of emerging theory and research on oneness self-perception and non-dual awareness. (shrink)

There is an important tension within Francis Bacon’s discussions of sense-perception. On the one hand, he sometimes seems to regard sense-percep­tion as a certain and unquestionable source of information about the world. On the other hand, he refers to errors, faults, desertions, and deceptions of the senses; indeed, he aims to offer a method which can remedy these errors. Thus, Bacon may appear conflicted about whether sense-perception provides reliable information about the world. But, I argue, (...) this appearance of a conflict is itself illusory. Bacon offers us a coherent and compelling account of sense-perception that acknowledges not only its weaknesses but also its strengths. I explain his account by exploring its roots in the atomist and natural magic traditions, drawing special attention to the similarity between Bacon’s response to skepticism and earlier atomist responses to skepticism. One of the key features of the view is the analogy between sense organs and scientific instruments, both of which infallibly register information based on causal principles. (shrink)

The nature of mystical experience has been hotly debated. Essentialists divide into two camps: 1) immediate identity beyond any subject-object structure 2) the mystical object maintaining some distinctness at the point of contact. Paul Tillich’s mystical a priori has some affinities with the former, while William James’ model of religious experience coheres only with the latter. Opposing the essentialists are constructivists. After noting some ironies of the constructivist position, this article elaborates difficulties with 1) the traditional model of pure (...) identity with the divine by certain mystics, 2) the Tillichian universal mystical awareness, and 3) the Jamesian direct perceptual model. Finally, it proposes that the human body and brain mediate mystical experience, which consists of a distinctive sense of bodily harmony conjoined with openness to the potentialities of an integrated environment, involving distinctive neurological processes.

My argument is that Chalmers' zombie fiction and his rigid-designator-argument going back on Kripke comes down to a petitio principii. Rather, at the core it appears to be more related to the essential 'privacy' of the phenomenal internal perspective. In return for Chalmers I argue that the 'principle self-preservation' of living organisms necessarily implies subjectivity and the emergence of sense. The comparison with a robot proves instructive. The mode of 'mere physical' being is transcended if, in the form of (...) phenomenal perception, sense appears on the stage of higher animals – a transition explained here as an emergence phenomenon based on the systemic co-operation of perception, valuation and action ('perc-val-act system'). Some fundamental considerations are added: Those consequences implied by the principle self-preservation reveal the natural-biological origin of the organism – primarily seeming a more insignificant circumstance – as a momentous fundamental difference (end-in-itself-character, subjectivity, constitution of sense) compared to technical artefacts (robot). And the emergentist approach indicates the – maybe paradoxical – possibility of a dualism of physical and psychical phenomena in an overall physical system, that is not dualistic at the same time.

It will be obvious to anyone with a slight knowledge of twentieth-century analytic philosophy that one of the central themes of this kind of philosophy is the nature of perception: the awareness of the world through the five senses of sight, touch, smell, taste, and hearing. Yet it can seem puzzling, from our twenty-first-century perspective, why there is a distinctively philosophical problem of perception at all. For when philosophers ask ‘what is the nature of perception?’, (...) the question can be confused with other, purely empirical, questions. For example: how do our sense-organs actually work? What are the mechanisms of smell and taste? How do vision and touch actually provide us with information about the world around us? There is much general agreement, in its broad outlines, about how to answer such questions empirically; but it is not clear what role, if any, philosophy has to play in answering these empirical questions. So if these were the only questions about the nature of perception, then it would not be clear exactly what the philosophy of perception is supposed to be about. (shrink)

The vast majority of theologians accept true news, sound senses and healthy working mind as sources of knowledge. Due to the fact that the mind is counted among the sources of knowledge, reason-based evidence has been used in many subjects. It is known that Māturīdī was the first theologian who dealt with the mentioned sources of knowledge in his work. At the very beginning of his Kitāb al-Tawhīd, he determined the ways of acquiring knowledge as correct news, sound senses and (...) reason, and elaborated them in detail. Māturīdī mostly prefers the term inference to describe the use of reason. He has proven his views on theological issues with many types of inference as well as true news and sense knowledge. These include matters related to the hereafter, too. The visible over the invisible, which is a type of inference, was used as evidence by Māturīdī to prove almost every subject. Many definitions of the method of the method the visible as an evidence for the invisible have been made. However, it is possible to understand the structure on which it is built as follows: There are areas that human beings cannot comprehend and have will no definite knowledge about. These areas called as al-ghaib “the invisible” may be related to ontological differences or may be due to differences in time and space. The difference between humans and Allah is ontological difference, and Allah is an ontological invisible for humans. While events that have not yet happened are invisible in terms of time, happenings what beyond the mountain for example, are invisible in terms of spatial difference. It is not possible for human beings to fully understand (perceive) the attributes of Allah, who is ontologically invisible. For this reason, many theologians have used the method the visible as an evidence for the invisible especially in making the attributes of Allah understandable and have tried to explain the divine attributes with this method. Belief in the hereafter is also related to the realm of the unvisible. There are a lot of revelations (true knowledge) about the hereafter. However, because of the conditions of the hereafter are different from this world, it is necessary to make the revelations about that place comprehensible. Accordingly, it is interesting how Māturīdī uses the aforementioned method to understand the nature of reward and punishment in the hereafter, which is the area of the unvisible. Māturīdī sometimes understood the verses about reward and punishment in the hereafter with their real meanings, and sometimes attributed different meanings to these verses. In this context, while dealing with the verses about the afterlife, he listed the possibilities regarding what they might mean, and included interpretations based the method the visible as an evidence for the invisible. Thus, Māturīdī tried to make the hereafter, intelligible based on human being’s experiences in this world. According to Māturīdī, the mind also has a function in understanding the hereafter. The mind has the capacity to go beyond the senses and gives us information about that field. Our mind, based on what we can perceive and understand, can go beyond itself and make inferences about the issues that are incapable of understanding. Knowing the pleasures and tortures of the world in order to understand the reward and punishment that will be given to humans in the hereafter happens in a similary way. In addition, he makes inferences based on events, situations, characteristics, etc. (visible) that people know from worldly life in order to better understand the expressions in such verses, which is quite remarkable for our study. In this context, while interpreting many verses, Māturīdī bases on the aspects of the realm of the visible similar to the realm of the hereafter. He explains the similarities of the hereafter to the worldly life, mostly through human nature, the Arabs’ perception of reward and punishment, and people’s perception of color and direction. In addition to these, he takes our knowledge, which has increased to the knowledge of observation, as a basis even though we learn through news, and evaluates the divine narrations for the hereafter on these principles. For the hereafter can be understood through things known, visible, lived and experienced in the life of this world. Māturīdī emphasizes the similarity of the world and the hereafter as well as the different aspects of the hereafter and uses these differences as a basis for his inferences. Our study is aimed at understanding how Māturīdī brings evidence to what people know from worldly life while explaining the nature of reward and punishment in the hereafter. In this context, methods such as interpretation, comparison, concept analysis, and literature review were used, and the study was limited to the books of Kitāb al-Tawhīd and Ta’wīlāt of Māturīdī.

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.

A recent turn in the cognitive sciences has deepened the attention on embodied and situated dynamics for explaining different cognitive processes such as perception, emotion, and social cognition. This has fostered an extensive interest in the social and ‘intersubjective’ nature of moral behavior, especially from the perspective of enactivism. In this paper, I argue that embodied and situated perspectives, enactivism in particular, nonetheless require further improvements with regards to their analysis of the social nature of human morality. (...) In brief, enactivist proposals still do not define what features of the social-relational context, or which kind of processes within social interactions, make an evaluation or action morally relevant or distinctive from other types of social normativity. As an alternative to this proclivity, and seeking to complement the enactive perspective, I present a definition of the process of moral sense-making and offer an empirically-based ethical distinction between different domains of social knowledge in moral development. For doing so, I take insights from the constructivist tradition in moral psychology. My objective is not to radically oppose embodied and enactive alternatives but to expand the horizon of their conceptual and empirical contributions to morality research. (shrink)

Why does aristotle say that the common sensibles are susceptible to error while the specific sensibles are not? various solutions of this problem are discussed and finally it is concluded that aristotle's meaning here is teleological. The specific senses were fashioned by nature to perceive the specific sensibles but not the common sensibles and so error sometimes (often) creeps in. The common sense is really not a sense faculty as the eye, The ear etc.

The essays in this volume explore those aspects of Kant’s writings which concern issues in the philosophy of mind. These issues are central to any understanding of Kant’s critical philosophy and they bear upon contemporary discussions in the philosophy of mind. Fourteen specially written essays address such questions as: What role does mental processing play in Kant’s account of intuition? What kinds of empirical models can be given of these operations? In what sense, and in what ways, are intuitions (...) object-dependent? How should we understand the nature of the imagination? What is inner sense, and what does it mean to say that time is the form of inner sense? Can we cognize ourselves through inner sense? How do we self-ascribe our beliefs and what role does self-consciousness play in our judgments? Is the will involved in judging? What kind of knowledge can we have of the self ? And what kind of knowledge of the self does Kant proscribe? These essays showcase the depth of Kant’s writings in the philosophy of mind, and the centrality of those writings to his wider philosophical project. Moreover, they show the continued relevance of Kant’s writings to contemporary debates about the nature of mind and self. Contents: 0. Introduction Anil Gomes and Andrew Stephenson 1.

This volume focuses on philosophical problems concerning sense perception in the history of philosophy. It consists of thirteen essays that analyse the philosophical tradition originating in Aristotle’s writings. Each essay tackles a particular problem that tests the limits of Aristotle’s theory of perception and develops it in new directions. The problems discussed range from simultaneous perception to causality in perception, from the representational nature of sense-objects to the role of conscious attention, and from (...) the physical/mental divide to perception as quasi-rational judgement. -/- The volume gives an equal footing to Greek, Arabic, and Latin philosophical traditions. It makes a substantial contribution not just to the study of the Aristotelian analysis of sense perception, but to its reception in the commentary tradition and beyond. Thus, the papers address developments in Alexander of Aphrodisias, Themistius, Avicenna, John of Jandun, Nicole Oresme, and Sayf al-Din al-Amidi, among others. The result of this is a coherent collection that attacks a well-defined topic from a wide range of perspectives and across philosophical traditions. (shrink)

Impressions, energy radiated by phenomena in the momentary environmental scene, enter sensory neurons, creating in afferent nerves a data stream. Following Kant, by our inner sense the mind perceives its own thoughts as it ties together sense data into an internalized scene. The mind, residing in the brain, logically a Language Machine, processes and stores items as coded grammatical entities. Kantian synthetic unity in the linguistic brain is able to deliver our experience of the scene as we appear (...) to see it. Uniquely, the brain records its own history, synthesizing a Movie-in-the-Brain, called the Noumenal Cosmos. Attempting thereby to represent the actual Universe, this makes for a sovereign brain that governs itself. The brain is domicile of an Ego, with its selfhood at stake at all times. Yet, it can know itself only by its actions, in which it appears as an actor in its own movie. Phenomena enter garbled, as confused apparitions, and must be put in good form using top–down feedback control by Ego, so that each movie frame makes rational sense within the overall context of the Noumenal Cosmos. A stack of frames is processed typically in 40 Hz rhythm with 300 ms process time each, for about 12 in the stack at any time. Successive neural centers are processing the stack in the brain assembly line, based on data from increasingly global receptive fields. Ego stitches together the movie frames, but only the top frame is in consciousness for 25 ms. The top frame contains the whole scene where the Ego makes an appearance as the actor that imposes Kantian synthetic unity on the scene, merely an assembly of grammatical texts, in a system-internal coded process language, fitting the scene into the Noumenal Cosmos. But Ego observes Ego only to the extent permitted by the objectivity rule, only what it does and thinks, not its true face. From the Noumenal Cosmos, the Ego receives grammatical messages in the internal sense code. They are integrated into a whole in the reaction of the Ego to the momentary scene. The voluntary nature of Ego’s decisions is explained, based on its ability to code in advance its own actions sequentially in time, as it sees fit with a view to an orderly Noumenal Cosmos, records of code being arranged spatially in neural structures.

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.

Recent work in cognitive and computational neuroscience depicts the brain as in some sense implementing probabilistic inference. This suggests a puzzle. If the processing that enables perceptual experience involves representing or approximating probability distributions, why does experience itself appear univocal and determinate, apparently bearing no traces of those probabilistic roots? In this paper, I canvass a range of responses, including the denial of univocality and determinacy itself. I argue that there is reason to think that it is our conception (...) of perception itself that is flawed. Once we see perception aright, as the slave of action, the puzzlement recedes. Perceptual determinacy reflects only the mundane fact that we are embodied, active, agents who must constantly engage the world they perceptually encounter. (shrink)

La théorie lockienne de la perception a été lue tantôt comme une forme de représentationnalisme, tantôt comme relevant d'un réalisme direct n'impliquant pas d'entité intermédiaire entre l'esprit et les choses. Cet article entreprend de clarifier cette question à partir des analyses de l'Essai sur la distinction et la confusion des idées. Celles-ci interrogent à la fois la nature de l'idée comme image et le fait qu'elle n'est déterminée que lorsque l'esprit lui donne un nom. Pour faire comprendre ce (...) dernier point, Locke utilise la métaphore de l'anamorphose en peinture, et plus particulièrement de l'anamorphose cylindrique. En reliant cette métaphore aux théories de la perspective du XVIIe siècle, à la camera obscura de l'esprit, et enfin à l'optique du XVIIe siècle, l'article parvient à plusieurs conclusions. Faire de l'idée une image ne conduit jamais Locke à voir en elle un objet qui s'interpose entre l'esprit et les choses. Une idée comme celle de sense data est étrangère à sa pensée. Si Locke ne met jamais en doute la réalité du monde extérieur, c'est que pour lui l'idée nous donne d'emblée accès à une extériorité, qu'il s'agit de déterminer. Enfin, la perception lockienne ne relève pas d'un modèle sémantique dont l'origine serait à trouver dans Descartes et qui préparerait celui de l'empirisme du XVIIIe siècle, faisant de l'idée un signe. Elle se rapprocherait plutôt, paradoxalement, de l'idée austinienne du silence des sens. (shrink)

The phenomenology of agency and perception is probably underpinned by a common cognitive system based on generative models and predictive coding. I defend the hypothesis that this cognitive system explains core aspects of the sense of having a self in agency and perception. In particular, this cognitive model explains the phenomenological notion of a minimal self as well as a notion of the narrative self. The proposal is related to some influential studies of overall brain function, and (...) to psychopathology. These elusive notions of the self are shown to be the natural upshots of general cognitive mechanisms whose fundamental purpose is to enable agents to represent the world and act in it. (shrink)

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)

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)

We investigate the nature of the sense of presence that usually accompanies perceptual experience. We show that the notion of a sense of presence can be interpreted in two ways, corresponding to the sense that we are acquainted with an object, and the sense that the object is real. In this essay, we focus on the sense of reality. Drawing on several case studies such as derealization disorder, Parkinson’s disease and virtual reality, we argue (...) that the sense of reality is two-way independent from the spatial and sensory contents of experience. We suggest that the sense of reality is an affective experience akin to a metacognitive feeling. Finally, we present a potentially important implication of our account for the current debate between Intentionalism and Naïve Realism. Since perception is “opaque” with respect to the reality of what is perceived, Intentionalism cannot refer to the sense of reality as what differentiates perception from sensory-like experiences such as imaginings. In contrast, Naïve Realism has an independent explanation of the specificity of perception. (shrink)

This thesis explores Epicurus' attempt to establish sense-perception as the primary or basic means by which we can gain knowledge about the world. In It is argued that it was this aim, along with his belief that perceptions are all equal in trustworthiness, which lead him to maintain "All perceptions are true", this being the thesis that all sense-perceptions present states of affairs which actually obtain. The heart of the thesis is then a discussion of how Epicurus (...) dealt with apparent counter-examples to "All perceptions are true", which aims to establish that, for him, all such counter-examples are in fact instances of being mistaken about what is being presented. The thesis then discusses Epicurus' account of how people are able to trust the judgements they make on the basis of sense-perceptions, and how knowledge of the perceptible world serves as a basis for making judgements about the non-evident..

The essay attempts to delineate how Maurice Merleau-Ponty’s phenomenology of perception can be applied to theories of sign processes, and how it reworks the framework of the phenomenalist conception of communication. His later philosophy involved a reformulation of subjectivity and a resolution of the subject/object dualism. My claim is that this non-reductionist theory of perception reveals a different view of nature as we experience it in an expressive and meaningful interaction. The perspective that another living being has (...) and communicates entails a form of depth, the invisible dimension of the visible or audible. These two aspects of perception and dialogue are intertwined in a dialectic of presence and absence, so that sense arises in the perceptual field rather than in subjectivity. This, I argue, is the most fundamental result of his theory. The origination of meaning in the workings of the chiasm of visible and invisible in perception opens up an objective sense of intersubjective nature. The essay also deals with the role of the phenomenological reduction; a suspension of beliefs and existence claims in experience. The reduction enables us to take a step back and look more closely at our understanding of nature in light of the historical and cultural influence on our thinking. (shrink)

Metaphysical and epistemological commitments seem to determine the course of research in the field of logic as well as its theoretical interpretation. What we take the objects of logical investigation to be determines our views on how they are to be known, and our view of the possible types of knowledge in turn places restrictions on what kinds of things those objects could be. Perhaps it is true that logical studies can be pursued to great lengths without indulging in general (...) declarations about the nature of reality or of human knowledge. But to say this is very far from admitting the possibility of “logic without ontology.” The thoughtful beginning student in logic quickly wants to know what it is he or she is really studying and what, precisely, it has to do with the real worlds. The slightest philosophical stimulation will lead him or her, further, to ask about the evidence supporting the various sorts of claims made as the course progresses, and about the methodology of logic from a scientific point of view. Rarely is any answer given to such questions, much less a reasonable and well elaborated one. Questions of this type are usually discouraged and avoided by text books and instructors, and there may even be some suggestion that to ask them evidences confusion and stupidity. But when they are pressed it turns out that logic as a field of knowledge and inquiry remains in chaos at its philosophical foundations. I mean by this that the leading investigators cannot agree—indeed, they disagree in dimensions categorial—concerning what the subject of logical knowledge is, and concerning the modes of logical knowledge.

This remarkable book--the fruit of almost two decades of study--traces in compelling fashion the changes in Western attitudes toward death and dying from the earliest Christian times to the present day. A truly landmark study, The Hour of Our Death reveals a pattern of gradually developing evolutionary stages in our perceptions of life in relation to death, each stage representing a virtual redefinition of human nature. Starting at the very foundations of Western culture, the eminent historian Phillipe Aries shows (...) how, from Graeco-Roman times through the first ten centuries of the Common Era, death was too common to be frightening; each life was quietly subordinated to the community, which paid its respects and then moved on. Aries identifies the first major shift in attitude with the turn of the eleventh century when a sense of individuality began to rise and with it, profound consequences: death no longer meant merely the weakening of community, but rather the destruction of self. Hence the growing fear of the afterlife, new conceptions of the Last Judgment, and the first attempts (by Masses and other rituals) to guarantee a better life in the next world. In the 1500s attention shifted from the demise of the self to that of the loved one (as family supplants community), and by the nineteenth century death comes to be viewed as simply a staging post toward reunion in the hereafter. Finally, Aries shows why death has become such an unendurable truth in our own century--how it has been nearly banished from our daily lives--and points out what may be done to "re-tame" this secret terror. The richness of Aries's source material and investigative work is breathtaking. While exploring everything from churches, religious rituals, and graveyards (with their often macabre headstones and monuments), to wills and testaments, love letters, literature, paintings, diaries, town plans, crime and sanitation reports, and grave robbing complaints, Aries ranges across Europe to Russia on the one hand and to England and America on the other. As he sorts out the tangled mysteries of our accumulated terrors and beliefs, we come to understand the history--indeed the pathology--of our intellectual and psychological tensions in the face of death.

Several studies have approached sense perception in the encyclopaedias of Thomas of Cantimpré, Bartholomew the Englishman and Vincent of Beauvais. Yet a systematic overview and comparison of the arrangement of sense perception in these encyclopaedias is still lacking. The overview offered here shows that all encyclopaedias place sense perception beside expositions on psychology and anatomy. There are, however, significant differences in how they treat the objects of sensation. In the case of Bartholomew and Vincent, (...) I argue, these differences reflect two different readings of Aristotle. (shrink)

Several studies have approached sense perception in the encyclopaedias of Thomas of Cantimpré, Bartholomew the Englishman, and Vincent of Beauvais. A comparative analysis of these encyclopaedias shows that all of them arrange sense perception in accordance with the expositions on the soul and with human and animal anatomy. Yet there are significant differences in how they treat the objects of sensation: Thomas does not refer to them at all, Bartholomew considers them to be “accidents,” and Vincent (...) deals with them separately when discussing the features of the sensible world. These differences, I argue, respond to two different readings of Aristotle. (shrink)

In this dissertation, I provide an interpretation and defense of Merleau-Ponty's thesis of the primacy of perception, namely, the thesis that all knowledge is founded in perceptual experience. I take as an interpretative and argumentative key Merleau-Ponty's phenomenological conception of motivation. Whereas epistemology has traditionally accepted a dichotomy between reason and natural causality, I show that this dichotomy is not exhaustive of the forms of epistemic grounding. There is a third type of grounding, the one characteristic of the grounding (...) relations found in perception: motivation. I argue that introducing motivation as a form of epistemic grounding allows us to see how Merleau-Ponty's thesis of the primacy of perception avoids both rationalism and empiricism. Whereas empiricism has argued that all the content of our knowledge is grounded in causal interactions between the world and our senses, and rationalism has held that experience does not suffice as a reason for knowledge, thinking of the relation between experience and knowledge in terms of motivation accommodates the best insights of rationalism and empiricism. Motivation allows us to see how knowledge can be grounded in experience without the content of knowledge being reducible to that of experience. (shrink)

Experts from wine tasters to radiologists to bird watchers have all undergone perceptual learning-long-term changes in perception that result from practice or experience. Philosophers have been discussing such cases for centuries, from the 14th-century Indian philosopher Vedanta Desika to the 18th-century Scottish philosopher Thomas Reid, and into contemporary times. -/- This book uses recent evidence from psychology and neuroscience to show that perceptual learning is genuinely perceptual, rather than post-perceptual. It also offers a taxonomy for classifying cases in the (...) philosophical literature. In some cases, perceptual learning involves changes in how one attends; in other cases, it involves a learned ability to differentiate two properties, or to perceive two properties as unified. Connolly uses this taxonomy to rethink several domains of perception in terms of perceptual learning, including multisensory perception, color perception, and speech perception. -/- As a whole, the book offers a theory of the function of perceptual learning. Perceptual learning embeds into our quick perceptual systems what would be a slower task were it to be done in a controlled, cognitive manner. A novice wine taster drinking a Cabernet Sauvignon might have to think about its features first and then infer the type of wine, while an expert can identify it immediately. This learned ability to immediately identify the wine enables the expert to think about other things like the vineyard or the vintage of the wine. More generally, perceptual learning serves to free up cognitive resources for other tasks. This book offers a comprehensive empirically-informed account, and explores the nature, scope, and theoretical implications of perceptual learning. (shrink)

This paper proposes a set of criteria for an appropriate experiment on the issue of the theory ladenness of perception. These criteria are used to select a number of experiments that use: belief-based ambiguous figures, fragmented figures, or memory color. Crucially, the data in experiments of this type are based on the participant’s qualitative visual experience. Across many different types of experimental designs, different types of stimuli, and different types of belief manipulation, these experiments show the impact of belief/theory (...) on visual perception. Using an ecological validity argument, I conclude that attention-based interpretations of these findings are not successful because the relevant epistemological issues only require that we examine final perception, in the sense of visual awareness of the everyday world. Finally, I argue that the epistemological consequences of theory-ladenness can be reduced by using a top-down/bottom-up theoretical framework and by adopting appropriate methodological procedures to data derived from individual observations.
