Many of Margaret Cavendish’s criticisms of Thomas Hobbes in the Philosophical Letters (1664) relate to the disorder and damage that she holds would result if Hobbesian pressure were the cause of visual perception. In this paper, I argue that her “two men” thought experiment in Letter IV is aimed at a different goal: to show the explanatory potency of her account. First, I connect Cavendish’s view of visual perception as “patterning” to the “two men” thought experiment in Letter (...) IV. Second, I provide a potential reply on Hobbes’s behalf that appeals to physiological differences between perceivers’ sense organs, drawing upon Hobbes’s optics in De homine. Third, I argue that such a reply would misunderstand Cavendish’s objective of showing the limited explanatory resources available in understanding visual perception as pressing when compared to her view of visual perception as patterning.

Here are four examples of “seeing.” You see that something green is wriggling. You see that an iguana is in distress. You see that someone is wrongfully harming an iguana. You see that torturing animals is wrong. The first is an example of low-level perception. You visually represent color and motion. The second is an example of high-level perception. You visually represent kind properties and mental properties. The third is an example of moral perception. You have an (...) impression of moral properties. The fourth is an example of intuition. You intellectually grasp a general moral truth. Should moral perceptions be thought of as high-level perceptions or as intuitions? Most proponents of moral perception have thought of them as high-level perceptions. I give epistemological and methodological reasons for thinking that at least some are examples of what I call low-level intuitions—experiences in which we both apprehend abstract generalities and apply them to concrete particulars.

When we see an object, we also represent those parts of it that are not visible. The question is how we represent them: this is the problem of amodal perception. I will consider three possible accounts: (a) we see them, (b) we have non-perceptual beliefs about them and (c) we have immediate perceptual access to them, and point out that all of these views face both empirical and conceptual objections. I suggest and defend a fourth account, according to which (...) we represent the occluded parts of perceived objects by means of mental imagery. This conclusion could be thought of as a (weak) version of the Strawsonian dictum, according to which “imagination is a necessary ingredient of perception itself”. (shrink)

Kant argued that the perceptual representations of space and time were templates for the perceived spatiotemporal ordering of objects, and common to all modalities. His idea is that these perceptual representations were specific to no modality, but prior to all—they are pre-modal, so to speak. In this paper, it is argued that active perception—purposeful interactive exploration of the environment by the senses—demands premodal representations of time and space.

This study examined students’ perception of rape and sexual violence and methods of prevention in tertiary institutions in Lagos State. It was a cross-sectional study carried out among one thousand, two hundred and eleven (1,211) female undergraduates selected from two tertiary institutions in Lagos State. The sample size for the study was one hundred and twenty-one (121) representing 10% of the population. Inferential statistics was used for analysis. The results revealed that majority of the students are aware of the (...) different types of rape but did not consider forced sexual intercourse between spouses as rape. The students have a good knowledge of rape and sexual violence. The students perceive that rape can have detrimental effects on the victims’ mental, physical and reproductive health. Avoiding late nights, dressing decently, increasing the presence of security officers at strategic places on campus and the likes were identified ways of preventing rape in tertiary institutions. Among the recommendations proffered are that students should review their dressing styles to conform to the morals of the society to prevent the occurrence of rape. (shrink)

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

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

One necessary condition on any adequate account of perception is clarity regarding whether unconscious perception exists. The issue is complicated, and the debate is growing in both philosophy and science. In this paper we consider the case for unconscious perception, offering three primary achievements. First, we offer a discussion of the underspecified notion of central coordinating agency, a notion that is critical for arguments that purportedly perceptual states are not attributable to the individual, and thus not genuinely (...) perceptual. We develop an explication of what it is for a representational state to be available to central coordinating agency for guidance of behavior. Second, drawing on this explication, we place a more careful understanding of the attributability of a state to the individual in the context of a range of empirical work on vision-for-action, saccades, and skilled typing. The results place pressure on the skeptic about unconscious perception. Third, reflecting upon broader philosophical themes running through debates about unconscious perception, we highlight how our discussion places pressure on the view that perception is a manifest kind, rather than a natural kind. In doing so, we resist the tempting complaint that the debate about unconscious perception is merely verbal. (shrink)

In this Introduction we introduce the central themes of the Evaluative Perception volume. After identifying historical and recent contemporary work on this topic, we discuss some central questions under three headings: (1) Questions about the Existence and Nature of Evaluative Perception: Are there perceptual experiences of values? If so, what is their nature? Are experiences of values sui generis? Are values necessary for certain kinds of experience? (2) Questions about the Epistemology of Evaluative Perception: Can evaluative experiences (...) ever justify evaluative judgments? Are experiences of values necessary for certain kinds of justified evaluative judgments? (3) Questions about Value Theory and Evaluative Perception: Is the existence of evaluative experience supported or undermined by particular views in value theory? Are particular views in value theory supported or undermined by the existence of value experience? (shrink)

Traditional accounts of the perception/cognition divide tend to draw it in terms of subpersonal psychological processes, processes into which the subject has no first-person insight. Whatever betides such accounts, there seems to also be some first-personally accessible difference between perception and thought. At least in normal circumstances, naïve subjects can typically tell apart their perceptual states from their cognitive or intellectual ones. What are such subjects picking up on when they do so? This paper is an inconclusive search (...) for an answer. At its end, I conclude, without joy, that we may have to simply accept the perception/cognition distinction as a primitive and inexplicable bright line within the sphere of conscious phenomena.

According to a traditional view, there is no categorical difference between the phenomenology of perception and the phenomenology of imagination; the only difference is in degree (of intensity, resolution, etc.) and/or in accompanying beliefs. There is no categorical difference between what it is like to perceive a dog and what it is like to imagine a dog; the former is simply more vivid and/or is accompanied by the belief that a dog is really there. A sustained argument against this (...) traditional view is prosecuted by Sartre, who develops an alternative according to which there is a categorical difference between the two phenomenologies. This paper draws on Sartre’s work in this area to develop a similar account of perception and imagination as categorically different. (shrink)

It seems plausible that visual experiences of darkness have perceptual phenomenal content that clearly differentiates them from absences of visual experiences. I argue, relying on psychological results concerning auditory attention, that the analogous claim is true about auditory experiences of silence. More specifically, I propose that experiences of silence present empty spatial directions like ‘right’ or ‘left’, and so have egocentric spatial content. Furthermore, I claim that such content is genuinely auditory and phenomenal in the sense that one can, in (...) principle, recognize that one is experiencing silence. This position is far from obvious, as the majority of theories concerning silence perception do not ascribe perceptual phenomenal content to experiences of silence. (shrink)

We intend to demonstrate that human perception is better understood when thought from the perspective of Aristotelian-Thomistic Philosophy. After concluding for its existence, Descartes, in the 17th century, concludes that there are ideas that we all possess, such as the idea of “perfection”. This idea cannot result from experience, and it’s God the source of the idea of perfection in us, and the one who guarantees the existence not only of external reality but also of our own correct reasoning. (...) Very far from the God of Thomas Aquinas who is Alpha and Omega, Descartes' god is a god situated and secondary between the subject and reality which, in turn, is guaranteed by God, in a vicious circle between God and the subject. It’s a subjective or logical God, such as Kant's, but not a real God. Reality is, therefore, subjectively intelligible and truth objectively achieved, and the principle of causality is, in this way, subjectively valid. Reality is intelligible not because it’s provided by intelligible forms — by intelligible (and not only sensitive matter) that we, in fact, perceive — but because it is a reality presented by extension that is nothing more than a reflection of the logical-mathematical universe, thought by Modernity and which, with this thinker, is innate to the subject. This is a pure and finished reason. The extensive reality is purged of subjective elements; it is logical-mathematical (therefore, it is thought). It’s a kind of idealism and not realism and which results in a physicalist and materialist view of reality. Materialism, called physicalism in mainstream culture, consists of the idea that there is a world out there that is not experiential. It is material, but the way the word is used here has a strict conceptual definition. Matter is something that can be specifically described by numbers. It's a world without qualities. The world is purely quantitative and, because we are part of this world, we are also quantitative. The entire world of qualities that, deep down, constitutes our reality, is generated, according to materialism, in a not very well specified way and by a brain inside our head. The world outside has no flavors, colors, smells or sounds. We cannot see it because it has no qualities. The best we can do is imagine it as some kind of set of mathematical equations floating in the void. (shrink)

I aim to show that perception depends counterfactually on the action we want to perform. Perception is not all-purpose: what we want to do does influence what we see. After clarifying how this claim is different from the one at stake in the cognitive penetrability debate and what counterfactual dependence means in my claim, I will give a two-step argument: one’s perceptual attention depends counterfactually on one’s intention to perform an action and one’s perceptual processing depends counterfactually on (...) one’s perceptual attention. If we put these claims together, what we get is that one’s perceptual processing depends counterfactually on one’s intention to perform an action. (shrink)

The success of the Bayesian approach to perception suggests probabilistic perceptual representations. But if perceptual representation is probabilistic, why doesn't normal conscious perception reflect the full probability distributions that the probabilistic point of view endorses? For example, neurons in MT/V5 that respond to the direction of motion are broadly tuned: a patch of cortex that is tuned to vertical motion also responds to horizontal motion, but when we see vertical motion, foveally, in good conditions, it does not look (...) at all horizontal. This article argues that the best Bayesian approach to this problem does not require probabilistic representation. (shrink)

The experiments reported herein probe the visual cortical mechanisms that control near–far percepts in response to two-dimensional stimuli. Figural contrast is found to be a principal factor for the emergence of percepts of near versus far in pictorial stimuli, especially when stimulus duration is brief. Pictorial factors such as interposition (Experiment 1) and partial occlusion Experiments 2 and 3) may cooperate, as generally predicted by cue combination models, or compete with contrast factors in the manner predicted by the FACADE model. (...) In particular, if the geometrical conŽ guration of an image favors activation of cortical bipole grouping cells, as at the top of a T-junction, then this advantage can cooperate with the contrast of the conŽ guration to facilitate a near–far percept at a lower contrast than at an X-junction. Varying the exposure duration of the stimuli shows that the more balanced bipole competition in the X-junction case takes longer exposure times to resolve than the bipole competition in the T-junction case (Experiment 3).

Predictive approaches to the mind claim that perception, cognition, and action can be understood in terms of a single framework: a hierarchy of Bayesian models employing the computational strategy of predictive coding. Proponents of this view disagree, however, over the extent to which perception is direct on the predictive approach. I argue that we can resolve these disagreements by identifying three distinct notions of perceptual directness: psychological, metaphysical, and epistemological. I propose that perception is plausibly construed as (...) psychologically indirect on the predictive approach, in the sense of being constructivist or inferential. It would be wrong to conclude from this, however, that perception is therefore indirect in a metaphysical or epistemological sense on the predictive approach. In the metaphysical case, claims about the inferential properties of constructivist perceptual mechanisms are consistent with both direct and indirect solutions to the metaphysical problem of perception (e.g. naïve realism, representationalism, sense datum theory). In the epistemological case, claims about the inferential properties of constructivist perceptual mechanisms are consistent with both direct and indirect approaches to the justification of perceptual belief. In this paper, I demonstrate how proponents of the predictive approach have conflated these distinct notions of perceptual directness and indirectness, and I propose alternative strategies for developing the philosophical consequences of the approach.

Direct Social Perception (DSP) is the idea that we can non-inferentially perceive others’ mental states. In this paper, I argue that the standard way of framing DSP leaves the debate at an impasse. I suggest two alternative interpretations of the idea that we see others’ mental states: others’ mental states are represented in the content of our perception, and we have basic perceptual beliefs about others’ mental states. I argue that the latter interpretation of DSP is more promising (...) and examine the kinds of mental states that plausibly could satisfy this version of DSP. (shrink)

This paper argues that a common form of representationalism has trouble accommodating empirical findings about visual space perception. Vision science tells us that the visual system systematically gives rise to different experiences of the same spatial property. This, combined with a naturalistic account of content, suggests that the same spatial property can have different veridical looks. I use this to argue that a common form of representationalism about spatial experience must be rejected. I conclude by considering alternatives to this (...) view. (shrink)

Perceptual processes differ from cognitive, this paper argues, in functioning to be causally controlled by proximal stimuli, and being modular, at least in a modest sense that excludes their being isotropic in Jerry Fodor's sense. This claim agrees with such theorists as Jacob Beck and Ben Phillips that a function of stimulus-control is needed for perceptual status. In support of this necessity claim, I argue, inter alia, that E.J. Green's recent architectural account misclassifies processes deploying knowledge of grammar as perceptual. (...) _Pace_ Beck and Phillips, however, I argue a function of stimulus-control is insufficient for perceptual as opposed to cognitive status. One consideration in favour of such insufficiency, noted but (I argue) not convincingly rebutted by these theorists, concerns perpetually grounded demonstrative thought. Two other considerations trade on the fact that a function of stimulus-control can arise not from blind nature but intentional design or social institutions, where so-functioning processes may but need not be perceptual. I offer two cases where such processes are cognitive, viz. skilful play-by-play announcing of ongoing events, and voluntary visualizing of ongoing events under the guidance of apt play-by-play announcements, dubbed announcement-driven visualizing (ADV). The cognitive status of these three diverse phenomena cannot be explained by an absence of a perception-like representational format or content (for ADV has such) or by a presence of personal-level mental states causally mediating between stimuli and outputs (for perception has such). A bettter explanation invokes, I argue, the non-modular character of the generating process. (shrink)

I argue for three main claims about Leibniz. (1) He views representation as a kind of structural correspondence between the representing thing and its target. (2) The primary sense in which he considers a perception or representation distinct, as opposed to confused, concerns the degree to which its structure is explicit or consciously accessible. (3) This is also the sense in which he takes concepts or ideas to be distinct.

Regardless of the metaphysics that inspires them, theories of perception invariably end up in the trap of subjectivism. Thus, idealism argues that the world can be nothing more than a representation of the mind. As to dualism and materialism, despite fundamental differences, they share the common assumption that perception is a subjective replica of external objects. Opposed to these theories is common sense with its tenacious belief that an external world exists and that things are perceived where they (...) are and as they are. This paper contends that Bergson’s theory of perception should be approached from the question of what the relationship between matter and mind must be for perception to retain an objective character. It shows that only its emergence from things themselves rather than from the subject can provide objectivity to perception. In thus grounding objectivity in the impersonal character of perception, whose implication is that it precedes the subject, which is then posteriorly formed, Bergson’s theory constitutes, so the paper argues, a radical reversal of the traditional position, including that of phenomenology.

While the view that we perceive aesthetic properties may seem intuitive, it has received little in the way of explicit defence. It also gives rise to a puzzle. The first strand of this puzzle is that we often cannot perceive aesthetic properties of artworks without training, yet much aesthetic training involves the acquisition of knowledge, such as when an artwork was made, and by whom. How, if at all, can this knowledge affect our perception of an artwork’s aesthetic properties? (...) The second strand of the puzzle arises when we widen the scope of aesthetic experience. The very same aesthetic properties that seem to require training for their perception in artworks do not appear to require training to perceive in objects of everyday aesthetic appreciation and natural phenomena. In this paper I argue that a prominent extant attempt to explain how training is compatible with aesthetic perception—cognitive permeation—is an inadequate solution. I also develop a positive view of aesthetic perception that provides a unified solution to both strands of the puzzle. (shrink)

Outside of philosophy, ‘intuition’ means something like ‘knowing without knowing how you know’. Intuition in this broad sense is an important epistemological category. I distinguish intuition from perception and perception from perceptual experience, in order to discuss the distinctive psychological and epistemological status of evaluative property attributions. Although it is doubtful that we perceptually experience many evaluative properties and also somewhat unlikely that we perceive many evaluative properties, it is highly plausible that we intuit many instances of evaluative (...) properties as such. The resulting epistemological status of evaluative property attributions is very much like it would be if we literally perceived such properties. (shrink)

According to G.E.M. Anscombe, an agent’s knowledge of his own intentional actions differs from his knowledge of his unintended behaviors as well as the knowledge others can have of what he intentionally does, in being secured “without observation”. I begin by posing a problem for any conception of this theory according to which non-observational knowledge must be independent of sense-perception, and criticize several recent attempts to get around the problem. Having done this, I develop an alternative account of non-observational (...) knowledge according to which its special character consists in the particular causal role of an agent’s self-awareness in bringing his intentional actions about.

This paper defends doubts about the existence of genuine moral perception, understood as the claim that at least some moral properties figure in the contents of perceptual experience. Standard examples of moral perception are better explained as transitions in thought whose degree of psychological immediacy varies with how readily non-moral perceptual inputs, jointly with the subject's background moral beliefs, training, and habituation, trigger the kinds of phenomenological responses that moral agents are normally disposed to have when they represent (...) things as being morally a certain way.

The possibilities of unconscious perception and unconscious bias prompt parallel debates about unconscious mental content. This chapter argues that claims within these debates alleging the existence of unconscious content are made fraught by ambiguity and confusion with respect to the two central concepts they involve: consciousness and content. Borrowing conceptual resources from the debate about unconscious perception, the chapter distills the two conceptual puzzles concerning each of these notions and establishes philosophical strategies for their resolution. It then argues (...) that empirical evidence for unconscious bias falls victim to these same puzzles, but that progress can be made by adopting similar philosophical strategies. Throughout, the chapter highlights paths forward in both debates, illustrates how they serve as fruitful domains in which to study the relationship between philosophy and empirical science, and uses their combined study to further understanding of a general theory of unconscious content.

Consciousness in the form of sense-certainty wants to apprehend its particular object as being-there (existing). But as demonstrated in previous articles in this series, the only truth of sense-certainty is merely that something is, and because everything is, being is universal. Here it will be shown that perception is the consciousness of the universal as the truth of a particular being. And because universality is the very principle of perception, both object and the I are also universal. Because (...) this universality is arrived at through a mediating process or thinking, it is not just an immediate ‘happening’ as is found in sense-certainty - rather, it proves to be a logically necessitated content.

Some have argued that we can put pressure on a relational view of experience with reference to the fact that the idiosyncrasies of perceivers can affect the qualitative characters of their experiences. Quassim Cassam calls this the problem of idiosyncratic perception. I defend the relational view in response to this problem.

Perception is typically distinguished from cognition. For example, seeing is importantly different from believing. And while what one sees clearly influences what one thinks, it is debatable whether what one believes and otherwise thinks can influence, in some direct and non-trivial way, what one sees. The latter possible relation is the cognitive penetration of perception. Cognitive penetration, if it occurs, has implications for philosophy of science, epistemology, philosophy of mind, and cognitive science. This paper offers an analysis of (...) the phenomenon, its theoretical consequences, and a variety of experimental results and possible interpretations of them. The paper concludes by proposing some constraints for analyses and definitions of cognitive penetrability. (shrink)

In this paper, I argue that perception justifies belief about the external world in virtue of its phenomenal character together with its relations to the external world. But I argue that perceptual relations to the external world impact on the justifying role of perception only by virtue of their impact on its representational content. Epistemic level-bridging principles provide a principled rationale for avoiding more radically externalist theories of perceptual justification.

“Perception is controlled hallucination,” according to proponents of predictive processing accounts of vision. I say they are right that something like this is a consequence of their view but wrong in how they have pursued the idea. The focus of my counterproposal is the causal theory of perception, which I develop in terms of a productive concept of causation. Cases of what otherwise seem like successful perception are instead mere veridical hallucination if predictive processing accounts are correct, (...) I argue, because of the role played within such accounts by absences, which cannot enter into productive causal relations. -/- I offer two arguments in support of the productive theory of perception. The first is loosely Kantian, focusing on the role that receptivity and spontaneity play in perception. The second focuses on what perception and hallucination have in common. I conclude with a series of objections and replies. (shrink)

How do we see the world aright? This question is central to Iris Murdoch’s philosophy as well as to that of her great source of inspiration, Simone Weil. For both of them, not only our action, but the very quality of our being depends on the ability to see things as they are, where vision is both a metaphor for immediate understanding and a literal expression of the requirement to train our perception so as to get rid of illusions. (...) For both, too, the method to achieve this goal is attention. For both, finally, attention requires a dethronement of the self, considered as the source of illusion. In this paper I investigate what moral perception means for each of these philosophers and how it operates through attention and its relationship with the self. I will show that, despite many striking similarities, Murdoch’s project does not equal ‘Weil minus God’, but offers a different concept of the self, a different understanding of its removal, and therefore a different picture of attention and moral perception. In evaluating both views, I will gesture towards a third way represented by Zen Buddhism, which both philosophers variously consider but do not embrace. (shrink)

We begin with a puzzle about how to intelligibly combine the active and passive elements of perception. For counsel, we turn to Augustine’s account of perception in De Trinitate. Augustine’s trinitarian account of perception offers an attractive resolution of our puzzle. Augustine’s resolution of our puzzle, however, cannot be straightforwardly adopted. It must be adapted. We end with speculation about how this might be done.

The essay compares Peirce's pragmatist approach to the problem of perceptual experience as a fallible foundation of knowledge to a sophisticated empiricist take on the issue. The comparison suggests that, while empiricism can accommodate the idea of perception as fallible, theoretically laden, and containing conjectural elements, the cardinal difference between pragmatism and empiricism consists in the pragmatist insistence on the intrinsic intelligibility of experience, which also serves as the ultimate source of all forms of intelligibility; whereas empiricism retains a (...) penchant for fitting experiences into abstract conceptual schemes.

What method should we use to determine the nature of perceptual experience? My focus here is the Kantian thought that transcendental arguments can be used to determine the nature of perceptual experience. I set out a dilemma for the use of transcendental arguments in the philosophy of perception, one which turns on a comparison ofthe transcendental method with the first-personal method of early analytic philosophy, and with the empirical methods of much contemporary philosophy of mind. The transcendental method can (...) avoid this dilemma only if it commits to our possessing a capacity for imaginative reflection, one which is capable of identifying certain formal properties of experience.This result indicates some of the commitments which must be made if transcendental arguments are to be used in the philosophy of perception, and it has implications for those views that take the philosophy of perception to be autonomous of the empirical science of perception.

In this paper I suggest ways in which vision theory and psychology of perception may illuminate our understanding of beauty. I identify beauty as a phenomenon which is (i) ineffable, (ii) subjectively universal (intersubjective), and (iii) manifested in objects as formal structure. I present a model of perception by which I can identify a representation whose underlying principles would explain these features of beauty. The fact that these principles underlie the representation rather than constitute the content of representation, (...) provides an explanation for the ineffability and subjective universality of the perception of beauty in the form of objects. In part one, I set out two models of perception conducive to this approach. In part two, I suggest how such theories can offer a way of explaining and understanding the experience of beauty.

Auditory perception is traditionally conceived as the perception of sounds — a friend’s voice, a clap of thunder, a minor chord. However, daily life also seems to present us with experiences characterized by the absence of sound — a moment of silence, a gap between thunderclaps, the hush after a musical performance. In these cases, do we positively hear silence? Or do we just fail to hear, and merely judge or infer that it is silent? This longstanding question (...) remains controversial in both the philosophy and science of perception, with prominent theories holding that sounds are the only objects of auditory experience and thus that our encounter with silence is cognitive, not perceptual. However, this debate has largely remained theoretical, without a key empirical test. Here, we introduce a novel empirical approach, presenting experimental evidence that silence can be genuinely perceived (not just cognitively inferred). We ask whether silences can ‘substitute’ for sounds in event-based auditory illusions — empirical signatures of auditory event representation in which auditory events distort perceived duration. Seven experiments introduce three new ‘silence illusions’ — the one-silence-is-more illusion, silence-based warping, and the oddball-silence illusion — each adapted from a prominent perceptual illusion previously thought to arise only from sounds. Subjects were immersed in ambient noise interrupted by silences structurally identical to the sounds in the original illusions. In all cases, silences elicited temporal distortions perfectly analogous to the illusions produced by sounds. Our results suggest that silence is truly heard, not merely inferred, introducing a general approach for studying absence perception. (shrink)

The notion of empathy has been explicated in different ways in the current debate on how to understand others. Whereas defenders of simulation-based approaches claim that empathy involves some kind of isomorphism between the empathizer’s and the target’s mental state, defenders of the phenomenological account vehemently deny this and claim that empathy allows us to directly perceive someone else’s mental states. Although these views are typically presented as being opposed, I argue that at least one version of a simulation-based approach—the (...) account given by de Vignemont and Jacob—is compatible with the direct-perception view. My argument has two parts: My first step is to show that the conflict between these accounts is not—as it seems at first glance—a disagreement on the mechanism by which empathy comes about. Rather, it is due to the fact that their proponents attribute two very different roles to empathy in understanding others. My second step is to introduce Stein’s account of empathy. By not restricting empathy to either one of these two roles, her process model of empathy helps to see how the divergent intuitions that have been brought forward in the current debate could be integrated.

According to Phillips, (1) genuine perception is attributable to the individual (i.e. it’s a personal state/event, as opposed to sub-personal states/events in the individual’s brain); (2) since unconscious perceptual representations are ill-suited to guide action, there’s no good reason to attribute them to the individual; (3) not being attributable to the individual, they don’t instantiate genuine perception, thereby failing to support the hypothesis that genuine perception can occur unconsciously. I argue that this reasoning is flawed and can’t (...) be easily fixed. Phillips contends that unconscious perceptual representations don’t guide action because they fail to meet certain conditions that are sufficient for action guidance. But those conditions may not be necessary for action guidance. Consequently, unconscious perceptual representations may guide action even if they don’t meet Phillips’ conditions. Furthermore, due to his commitment to the distinction between personal and sub-personal states/events, Phillips isn’t in a position to argue that his conditions are necessary for action guidance. For the distinction applies to action as well as to perception, and when genuine action is identified by personal-level criteria, Phillips’ conditions turn out unnecessary for action guidance.

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

The paper argues -- against the standard view in metaphysics -- that the existence of ordinary objects like tomatoes is (near-enough) established by the fact that such things are apparently encountered in perception.

The phenomenal character of perceptual experience involves the representation of colour, shape and motion. Does it also involve the representation of high-level categories? Is the recognition of a tomato as a tomato contained within perceptual phenomenality? Proponents of a conservative view of the reach of phenomenal content say ’No’, whereas those who take a liberal view of perceptual phenomenality say ’Yes’. I clarify the debate between conservatives and liberals, and argue in favour of the liberal view that high-level content can (...) directly inform the phenomenal character of perception. (shrink)

Is temporal representation constitutively necessary for perception? Tyler Burge (2010) argues that it is, in part because perception requires a form of memory sufficiently sophisticated as to require temporal representation. I critically discuss Burge’s argument, maintaining that it does not succeed. I conclude by reflecting on the consequences for the origins of temporal representation.

In this paper, I explore Augustine’s account of sense cognition in book 11 of De Trinitate. His discussion in this context focuses on two types of sensory state—what he calls “outer vision” and “inner vision,” respectively. His analysis of both types of state is designed to show that cognitive acts involving external and internal sense faculties are susceptible of a kind of trinitarian analysis. A common way to read De Trin. 11, is to interpret Augustine’s account of “outer” vision as (...) an analysis of sense perception and his account “inner” vision as an analysis of occurrent sensory memory and imagination. I argue against such a reading of De Trin. 11, however. Insofar as we take perception to be a phenomenally conscious mode of sensory awareness, outer vision cannot, I claim, be the equivalent of ordinary sense perception. For, on Augustine’s view, the deliverances of outer vision only reach the threshold of consciousness, when outer vision occurs in conjunction with inner vision. Hence, on my analysis, sense perception turns out to be a complex, hybrid state—one that involves both outer and inner vision. If I am right, acts of sense perception turn out not to be directly susceptible to trinitarian analysis. Even so, the account is interesting and nuanced for all that. (shrink)

It has been argued that picture perception is sometimes, but not always, ‘inflected’. Sometimes the picture’s design ‘inflects’, or is ‘recruited’ into the depicted scene. The aim of this paper is to cash out what is meant by these metaphors. Our perceptual state is different when we see an object fact to face or when we see it in a picture. But there is also a further distinction: our perceptual state is very different if we perceive objects in pictures (...) in an inflected or uninflected manner. The question is what this difference amounts to. My answer is that it is a difference of attention. In the case of inflected, but not uninflected, picture perception, we are consciously attending to certain properties: to relational property that cannot be fully characterized without reference to both the picture’s design and to the depicted object. I defend this way of interpreting inflected picture perception from some important objections and emphasize the importance of this, inflected, way of perceiving pictures. (shrink)

Is perception cognitively penetrable, and what are the epistemological consequences if it is? I address the latter of these two questions, partly by reference to recent work by Athanassios Raftopoulos and Susanna Seigel. Against the usual, circularity, readings of cognitive penetrability, I argue that cognitive penetration can be epistemically virtuous, when---and only when---it increases the reliability of perception.

A compositional theory of perceptual representations would explain how the accuracy conditions of a given type of perceptual state depend on the contents of constituent perceptual representations and the way those constituents are structurally related. Such a theory would offer a basic framework for understanding the nature, grounds, and epistemic significance of perception. But an adequate semantics of perceptual representations must accommodate the holistic nature of perception. In particular, perception is replete with context effects, in which the (...) way one perceptually represents one aspect of a scene (including the position, size, orientation, shape, color, motion, or even unity of an object) normally depends on how one represents many other aspects of the scene. The ability of existing accounts of the semantics of perception to analyze context effects is at best unclear. Context effects have even been thought to call into question the very feasibility of a systematic semantics of perception. After outlining a compositional semantics for a rudimentary set of percepts, I draw on empirical models from perceptual psychology to show how such a theory must be modified to analyze context effects. Context effects arise from substantive constraints on how perceptual representations can combine and from the different semantic roles that perceptual representations can have. I suggest that context effects are closely tied to the objectivity of perception. They arise from a perceptual grammar that functions to facilitate the composition of reliably accurate representations in an uncertain but structured world. (shrink)

Scene Perception is the visual perception of an environment as viewed by an observer at any given time. It includes not only the perception of individual objects, but also such things as their relative locations, and expectations about what other kinds of objects might be encountered. -/- Given that scene perception is so effortless for most observers, it might be thought of as something easy to understand. However, the amount of effort required by a process often (...) bears little relation to its underlying complexity. A closer look shows that scene perception is a highly complex activity, and that any account of it must deal with several difficult issues: What exactly is a scene? What aspects of it do we represent? And what are the processes involved? Finding the answers to these questions has proven to be extraordinarily difficult. (shrink)
