This dissertation proposes the central elements of a Social Enactive Theory of Perception. According to SEP, perception consists in sensory-based practices of interaction with objects, events, and states of affairs that are socially constituted. I oppose the representational view that perception is an indirect contact with the world, consists of the passive receiving and processing of sensory input, is in need of constant assessment of accuracy, and is a matter of individuals alone. I share the basic enactivist (...) insight that perception is a type of activity, but I depart from standard enactivism on the grounds of its individualistic bias and its limited conception of activity. Instead of motor actions, I formulate the concept of perceptual practices as the appropriate framework to understand perception. Perception is woven into socially informed, contextual, sensory-based everyday activities, such as food, dance, and dress, and even seemingly independent, basic perceptual activities and concepts are constituted by such practices. Perceptual individual interactions instantiate social perceptual practices but are not just repetitions of a script. We perceive objects in virtue of perspectives or appearances, not in spite of them, and on this basis I offer SEPâs take on experience, properties, and contents. I conceive perceptual experience as finely grained interactions between subjects and objects, both of which are spatially, temporally, and pragmatically situated. Objects and their sensory properties are perceived dynamically and always in multiple appearances. Perceptual content offers a pragmatic specification of the perceptual objects in the specific ways they appear to subjects. For SEP, perception is normatively structured. SEPâs perceptual normativity is not a worry about a supposed constant threat that our perceptions be nonveridical, but about the placement of perceptual things in a system of possibilities and expectations, cast in terms of degrees of fulfillment of expectations and in a horizon of pragmatic significance, both of which are functions of the socially constituted interactions between a perceiver and a rich theory of appearances.

Despite its admirable bottom-up methodology, Roy Sorensen's Seeing Dark Things (OUP, 2008) raises difficult theoretical questions concerning the metaphysics and perception of absences. Metaphysical difficulties include how to individuate, count, locate, and classify absences, and what determines their features. Perceptual difficulties include how to distinguish experiences of absences and presences, especially when nonveridical, and what subjects contribute to perceptual experience according to Sorensen's causal theory. In addition to articulating these difficulties, this paper also presents and explores, on Sorensen's (...) terms, an alternative account of silence. (shrink)

Brain-centered theories of consciousness seem to face insuperable difficulties. While some philosophers now doubt that the hard problem of consciousness will ever be solved, others call for radically new approaches to conscious experience. In this article I resurrect a largely forgotten approach to consciousness known as neorealism. According to neorealism, consciousness is merely a part, or cross-section, of the environment. Neorealism implies that all conscious experiences, veridical or otherwise, exist outside of the brain and are wholly independent of being perceived (...) or not; nonveridical perceptions of the environment over an arbitrarily short period of time are supposed to be objective constituents of the environment over a more extended time scale. I argue here that neorealism fares at least as well as brain-centered theories of consciousness on a number of fundamental issues. On one fundamental issue—the nature of the relation between veridical and nonveridical perceptions—neorealism outperforms its competitors. (shrink)

The main aim of this dissertation is to trace the systematic development of Husserl's early theory of intentionality, particularly as it reflects and influences his understanding of the mind-world relation. The dissertation is divided into two parts. ;In the first part, I trace the historical roots of phenomenology back to Husserl's teacher Franz Brentano. I argue that for Brentano, intentionality is a purely mental relation between a mental act and a mentally immanent intentional object or content. I also argue that (...) Brentano embeds this view in a roughly Lockean or "critical realist" position which adds a third element to the two elements of the intentional relation, viz., a really existing, extramental or worldly object---or, as Brentano prefers to call it, "thing." This "thing" is not psychologically accessible but is rather hypothesized by the natural scientist as a causal explanation for our intentional experiences. ;In the second part of the dissertation I chart the course of Husserl's early intellectual development in the period immediately following his philosophical apprenticeship under Brentano, again focusing on intentionality. I document Husserl's initial adoption of the Brentanian view, as well as his growing doubts about Brentano's immanentism. Through his work on the problem of nonveridical intentionality and the descriptive psychology of perception, Husserl is led to reject altogether the idea that intentionality is a genuine relation and to adopt instead an adverbial account which explains intentionality as an exclusive feature of mental acts, one that can be studied without any reference to the objects at which these acts aim. In the Logical Investigations , this conception of intentionality is coupled with a Cartesian, epistemologically oriented methodology to yield a conception of the philosophical study of the mind and its experiences in which no reference is made to the objects of the real world. I conclude the dissertation by indicating briefly how Husserl in subsequent years would augment and deepen this position through his concept of the noema. (shrink)

The notion of veridicality has and continues to play a significant role in both the psychology and philosophy of perception. This paper raises questions about the very idea of perceptual veridicality. In particular, it examines the role the veridical/nonveridical distinction plays in our conception of visual illusions and visual constancies.

This essay attempts to develop a psychologically informed semantics of perception reports, whose predictions match with the linguistic data. As suggested by the quotation from Miller and Johnson-Laird, we take a hallmark of perception to be its fallible nature; the resulting semantics thus necessarily differs from situation semantics. On the psychological side, our main inspiration is Marr's (1982) theory of vision, which can easily accomodate fallible perception. In Marr's theory, vision is a multi-layered process. The different layers (...) have filters of different gradation, which makes vision at each of them approximate. On the logical side, our task is therefore twofold • to formalise the layers and the ways in which they may refine each other, and • to develop logical means to let description vary with such degrees of refinement. The first task is formalised by means of an inverse systems of first order models, with reality appearing as its inverse limit. The second task is formalised by means of so-called conditional quantifiers, a new form of generalised quantification which can best be described as resource bounded quantification. We show that the logic provides for a semantics and pragmatics of direct perception reports. In particular, direct perception reports have a possibly nonveridical, approximative semantics, which becomes veridical only by virtue of our pragmatic expectation that what is perceived would continue to be the case, were we to perceive more accurately. It is a general feature of resource bounded logics that the underlying logics are weak, but that stronger principles can be obtained pragmatically, by strengthening the resource. For the logic of vision this feature is clarified by showing how changes in the resource capture different notions of partiality, and by studying how the perception verb interacts with connectives and quantifiers in different visual contexts. The inference Veridicality, which is now viewed rather as a nonmonotonic inference, is also studied in depth. We end with an attempt to buttress the proposed model by comparing it with suggestions put forward in Cognitive or Conceptual Semantics, in the literature on evidentials, and in Husserl's philosophy of 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)

In this work Tim Ingold provides a persuasive new approach to the theory behind our perception of the world around us. The core of the argument is that where we refer to cultural variation we should be instead be talking about variation in skill. Neither genetically innate or culturally acquired, skills are incorporated into the human organism through practice and training in an environment.They are as much biological as cultural.

There is an important division in the human mind between perception and reasoning. We reason from information that we have already, but perception is a means of taking in new information. Susanna Siegel argues that these two aspects of the mind become deeply intertwined when beliefs, fears, desires, or prejudice influence what we perceive.

Philosophy, scientific psychology, and common sense all distinguish perception from cognition. While there is little agreement about how the perception–cognition boundary ought to be drawn, one prominent idea is that perceptual states are dependent on a stimulus, or stimulus-dependent, in a way that cognitive states are not. This paper seeks to develop this idea in a way that can accommodate two apparent counterexamples: hallucinations, which are prima facie perceptual yet stimulus-independent; and demonstrative thoughts, which are prima facie cognitive (...) yet stimulus-dependent. The payoff is not only a specific proposal for marking the perception–cognition boundary, but also a deeper understanding of the natures of hallucination and demonstrative thought. (shrink)

The essays in this collection examine the moral import of emotion, motivation, judgment, perception, and group identifications, and explore how all these psychic capacities contribute to a morally good life. They examine moral exemplars and the "moral saints" debate, the morality of rescue during the Holocaust, role morality as lying between "personal" and "impersonal" perspectives, Carol Gilligan's theory of women and morality, Iris Murdoch's moral philosophy, and moral responsiveness in young children.

This collection of essays by eminent philosopher Fred Dretske brings together work on the theory of knowledge and philosophy of mind spanning thirty years. The two areas combine to lay the groundwork for a naturalistic philosophy of mind. The fifteen essays focus on perception, knowledge, and consciousness. Together, they show the interconnectedness of Dretske's work in epistemology and his more contemporary ideas on philosophy of mind, shedding light on the links which can be made between the two. The first (...) section of the book argues the point that knowledge consists of beliefs with the right objective connection to facts; two essays discuss this conception of knowledge's implications for naturalism. The next section articulates a view of perception, attempting to distinguish conceptual states from phenomenal states. A naturalized philosophy of mind, and thus a naturalized epistemology, is articulated in the third section. This collection will be a valuable resource for a wide range of philosophers and their students, and will also be of interest to cognitive scientists, psychologists, and philosophers of biology.

Most contemporary moral philosophy is concerned with issues of rationality, universality, impartiality, and principle. By contrast Laurence Blum is concerned with the psychology of moral agency. The essays in this collection examine the moral import of emotion, motivation, judgment, perception, and group identifications, and explore how all these psychic capacities contribute to a morally good life. Blum takes up the challenge of Iris Murdoch to articulate a vision of moral excellence that provides a worthy aspiration for human beings. Drawing (...) on accounts of non-Jewish rescuers of Jews during the Holocaust Blum argues that impartial principle can mislead us about the variety of forms of moral excellence. (shrink)

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.

[Penultimate draft] I present the perceptualist/representationalist theories of pain in broad outline and critically examine them in light of a competing view according to which awareness of pain is essentially introspective. I end the essay with a positive sketch of a naturalistic proposal according to which pain experiences are intentional but not fully representational. This proposal makes sense of locating pains in body parts as well as taking pains as subjective experiences.

Moral perceptualism is the view that perceptual experience is attuned to pick up on moral features in our environment, just as it is attuned to pick up on mundane features of an environment like textures, shapes, colors, pitches, and timbres. One important family of views that incorporate moral perception are those of virtue theorists and sensibility theorists. On these views, one central ability of the virtuous agent is her sensitivity to morally relevant features of situations, where this sensitivity is (...) often spoken of in perceptual terms. However, sensibility theorists have often not been careful to specify how to understand their claims about moral sensibilities as perceptual. In this paper, we distinguish between what we call Attentional Moral Perception and Contentful Moral Perception. We argue that sensibility theorists should endorse Attentional Moral Perception, because it has very powerful empirical evidence in its favor, and it can play all of the explanatory roles that the sensibility theorist needs in her theory of moral sensibilities.

Our perception of where touch occurs on our skin shapes our interactions with the world. Most accounts of cutaneous localisation emphasise spatial transformations from a skin-based reference frame into body-centred and external egocentric coordinates. We investigated another possible method of tactile localisation based on an intrinsic perception of ‘skin space’. The arrangement of cutaneous receptive fields (RFs) could allow one to track a stimulus as it moves across the skin, similarly to the way animals navigate using path integration. (...) We applied curved tactile motions to the hands of human volunteers. Participants identified the location midway between the start and end points of each motion path. Their bisection judgements were systematically biased towards the integrated motion path, consistent with the characteristic inward error that occurs in navigation by path integration. We thus showed that integration of continuous sensory inputs across several tactile RFs provides an intrinsic mechanism for spatial perception. (shrink)

We perceive a world of mind-independent macroscopic material objects such as stones, tables, trees, and animals. Our experience is the joint upshot of the way these things are and our route through them, along with the various relevant circumstances of perception; and it depends on the normal operation of our perceptual systems. How should we characterise our perceptual experience so as to respect its basis and explain its role in grounding empirical thought and knowledge? I offered an answer to (...) this question in Perception and its objects. Here I aim to clarify some of my central arguments and to develop and defend the position further in the light of subsequent critical discussion. (shrink)

Abstract The content of an emotion, unlike the content of a perception, is directly dependent on the motivational set of the subject experiencing the emotion. Given the instability of this motivational set, it might be thought that there is no sense in which emotions can be said to pick up information about the environment in the same way that perception does. Whereas it is admitted that perception tracks for us what is the case in the environment, no (...) such tracking relation, it is argued, holds between one's emotions and what they are about. It is to this worry – that the construal of the emotions as perceptions inevitably raises – that this paper tries to respond. In this paper, I suggest that when it is realized that one dimension of perception itself is directly dependent on the perceiver's perspective on her environment, then emotion, which is also essentially perspectival in this sense, bears the comparison with perception very well. After having clarified the nature and the role that perspective plays in perception, I argue that, in the case of emotions, the same perspectival role can be played by agents’ long-standing evaluative tendencies and character traits. The resulting conception of emotion as perception is then tested against possible objections. (shrink)

This paper presents a theory of how perception provides a basis for moral knowledge. To do this, the paper sketches a theory of perception, explores the sense in which moral perception may deserve that name, and explains how certain moral properties may be perceptible. It does not presuppose a causal account of moral properties. If, however, they are not causal, how can we perceive, say, injustice? Can it be observable even if injustice is not a causal property? (...) The paper answers these and other questions by developing an account of how moral properties, even if not causal, can figure in perception in a way that grounds moral knowledge. (shrink)

There are good, even if inconclusive, reasons to think that cognitive penetration of perception occurs: that cognitive states like belief causally affect, in a relatively direct way, the contents of perceptual experience. The supposed importance of – indeed as it is suggested here, what is definitive of – this possible phenomenon is that it would result in important epistemic and scientific consequences. One interesting and intuitive consequence entirely unremarked in the extant literature concerns the perception of art. Intuition (...) has it that knowledge about art changes how one aesthetically evaluates artworks. A profound explanation of this intuitive fact is that perceptual experiences vary with artistic expertise. Cognitive penetration provides an explanatory mechanism for this latter effect. What one knows or otherwise thinks about art may affect, in one of two ways sketched below, how one perceives art. Differences in aesthetic evaluation may follow, either because high-level aesthetic properties can be perceptually represented or because they causally depend on low-level perceptible properties. All of this lends credence to the hypothesis that the expert better judges art because she better perceives art. And she better perceives art because she better knows art. (shrink)

This paper develops a form of transcendental naïve realism. According to naïve realism, veridical perceptual experiences are essentially relational. According to transcendental naïve realism, the naïve realist theory of perception is not just one theory of perception amongst others, to be established as an inference to the best explanation and assessed on the basis of a cost-benefit analysis that weighs performance along a number of different dimensions: for instance, fidelity to appearances, simplicity, systematicity, fit with scientific theories, and (...) so on. Rather, naïve realism enjoys a special status in debates in the philosophy of perception because it represents part of the transcendental project of explaining how it is possible that perceptual experience has the distinctive characteristics it does. One of the potentially most interesting prospects of adopting a transcendental attitude towards naïve realism is that it promises to make the naïve realist theory of perception, in some sense, immune to falsification. This paper develops a modest form of transcendental naïve realism modelled loosely on the account of the reactive attitudes provided by Strawson in ‘Freedom and Resentment’, and suggests one way of understanding the claim that naïve realism is immune to falsification.

In this paper, I want to focus on the claim, prominently made by sensorimotor theorists, that perception is something we do. I will argue that understanding perceiving as a bodily doing allows for a strong non-dualistic position on the relation between experience and objective physical events, one which provides insight into why such relation seems problematic while at the same time providing means to relieve the tension. Next I will show how the claim that perception is something we (...) do does not stand in opposition to, and is not refuted by, the fact that we often have perceptual experience without moving. In arguing that cases of motionless perception and perception-like experience are still doings it will be pointed out that the same interactive regularities which are engaged in in active perception still apply to them. Explaining how past interactive regularities can influence current perception or perception-like experience in a way which remains true to the idea that perception is a doing, so I will argue, can be done by invoking the past -- the past itself, however, not its representation. The resulting historical, non-representational sensorimotor approach can join forces with Gibsonian ecological psychology -- provided that such is also understood along lines that don't invoke externalist remnants of contents.

Jody Azzouni argues that we involuntarily experience certain physical items, certain products of human actions, and certain human actions themselves as having meaning-properties. We understand these items as possessing meaning or as having truth values. For example, a sign on a door reading "Drinks Inside" strikes native English speakers as referring to liquids in the room behind the door. The sign has a truth value--if no drinks are found in the room, the sign is misleading. Someone pointing in a direction (...) has the same effect: we experience her gesture as significant. Azzouni does not suggest that we don't recognize the expectations or intentions of speakers ; we do recognize that the person pointing in a certain direction intends for us to understand her gesture's significance. Nevertheless, Azzouni asserts that we experience that gesture as having significance independent of her intentions. The gesture is meaningful on its own. The same is true of language, both spoken and written. We experience the meanings of language artifacts as independent of their makers' intentions in the same way that we experience an object's shape as a property independent of the object's color. There is a distinctive phenomenology to the experience of understanding language, and Semantic Perception shows how this phenomenology can be brought to bear as evidence for and against competing theories of language.

There is a certain excitement in vision science concerning the idea of applying the tools of bayesian decision theory to explain our perceptual capacities. Bayesian models are thought to be needed to explain how the inverse problem of perception is solved, and to rescue a certain constructivist and Kantian way of understanding the perceptual process. Anticlimactically, I argue both that bayesian outlooks do not constitute good solutions to the inverse problem, and that they are not constructivist in nature. In (...) explaining how visual systems derive a single percept from underdetermined stimulation, orthodox versions of bayesian accounts encounter a problem. The problem shows that such accounts need to be grounded in Natural Scene Statistics (NSS), an approach that takes seriously the Gibsonian insight that studying perception involves studying the statistical regularities of the environment in which we are situated. Additionally, I argue that bayesian frameworks postulate structures that hardly rescue a constructivist way of understanding perception. Except for percepts, the posits of bayesian theory are not representational in nature. bayesian perceptual inferences are not genuine inferences. They are biased processes that operate over nonrepresentational states. (shrink)

According to the perceptual theory of emotions, emotions are perceptions of evaluative properties. The account has recently faced a barrage of criticism recently by critics who point out varies disanalogies between emotion and paradigmatic perceptual experiences. What many theorists fail to note however, is that many of the disanalogies that have been raised to exclude emotions from being perceptual states that represent evaluative properties have also been used to exclude high-level properties from appearing in the content of perception. This (...) suggests that emotions are perceptions of high level properties and perceptual theorists can marshal the arguments used by proponents of high-level perception to defend the perceptual theory. This paper therefore defends an account of emotion as high-level perception. (shrink)

Anthony J. Lisska presents a new analysis of Thomas Aquinas's theory of perception. While much work has been undertaken on Aquinas's texts, little has been devoted principally to his theory of perception and less still on a discussion of inner sense. The thesis of intentionality serves as the philosophical backdrop of this analysis while incorporating insights from Brentano and from recent scholarship. The principal thrust is on the importance of inner sense, a much-overlooked area of Aquinas's philosophy of (...) mind, with special reference to the vis cogitativa. Approaching the texts of Aquinas from contemporary analytic philosophy, Lisska suggests a modest 'innate' or 'structured' interpretation for the role of this inner sense faculty. He argues that were it not for the vis cogitativa, Aquinas would be unable to account for an awareness of the principal ontological category in his metaphysics. (shrink)

Everson presents a comprehensive new study of Aristotle's account of perception and related mental capacities. Recent debate about Aristotle's theory of mind has focused on this account, which is Aristotle's most sustained and detailed attempt to describe and explain the behavior of living things. Everson places this account in the context of Aristotle's natural science as a whole, showing how Aristotle applies the explanatory tools he developed in other works to the study of perceptual cognition.

Sensory substitution devices provide through an unusual sensory modality (the substituting modality, e.g., audition) access to features of the world that are normally accessed through another sensory modality (the substituted modality, e.g., vision). In this article, we address the question of which sensory modality the acquired perception belongs to. We have recourse to the four traditional criteria that have been used to define sensory modalities: sensory organ, stimuli, properties, and qualitative experience (Grice, 1962), to which we have added the (...) criteria of behavioral equivalence (Morgan, 1977), dedication (Keeley, 2002), and sensorimotor equivalence (O’Regan & Noe¨, 2001). We discuss which of them are fulfilled by perception through sensory substitution devices and whether this favors the view that perception belongs to the substituting or to the substituted modality. Though the application of a number of criteria might be taken to point to the conclusion that perception with a sensory substitution device belongs to the substituted modality, we argue that the evidence leads to an alternative view on sensory substitution. According to this view, the experience after sensory substitution is a transformation, extension, or augmentation of our perceptual capacities, rather than being something equivalent or reducible to an already existing sensory modality. We develop this view by comparing sensory substitution devices to other ‘‘mind-enhancing tools’’ such as pen and paper, sketchpads, or calculators. An analysis of sensory substitution in terms of mind-enhancing tools unveils it as a thoroughly transforming perceptual experience and as giving rise to a novel form of perceptual interaction with the environment.

I develop a new account of perception on which it is metaphysically and explanatorily prior to illusion, hallucination, and perceptual experience. I argue that this view can rival the mainstream experience-first representationalist approach in explanatory power by using competences as a key theoretical tool: it can help to explain the nature of perception, how illusion and hallucination depend on it, and how cognitive science can help to explain in virtue of what we perceive. According to the Competence View, (...) perception is a kind of target-oriented activity that manifests the agent’s perceptual competence. This characterization of perception helps to explain the role of the subject in perception, as well as how perception has accuracy conditions. Illusion and hallucination are explained as degenerate exercises of perceptual competences. Lastly, I show the Competence View provides a flexible and robust framework for investigation in cognitive science. (shrink)

In this paper, I defend the view that we can have perceptual moral knowledge. First, I motivate the moral perception view by drawing on some examples involving perceptual knowledge of complex non‐moral properties. I argue that we have little reason to think that perception of moral properties couldn't operate in much the same way that our perception of these complex non‐moral properties operates. I then defend the moral perception view from two challenging objections that have yet (...) to be adequately addressed. The first objection is that the moral perception view has implausible commitments concerning the morally blind, people who would claim not to perceive wrongness. The second objection is that the moral perception view is not really compatible with a wide range of the main candidate moral theories. I argue that the moral empiricist has plausible responses to both of these objections. I then address three residual concerns that my defense raises. (shrink)

Students of perception have long puzzled over a range of cases in which perception seems to tell us distinct, and in some sense conflicting, things about the world. In the cases at issue, the perceptual system is capable of responding to a single stimulus — say, as manifested in the ways in which subjects sort that stimulus — in different ways. This paper is about these puzzling cases, and about how they should be characterized and accounted for within (...) a general theory of perception. After rehearsing the sort of case at issue (§1), I’ll examine critically some of the strategies by which philosophers and perceptual psychologists have attempted to account for them (§2). Finally, I’ll present an alternative computational account of the puzzle cases, argue that this view is superior to its competitors, and examine some of its implications (§3). (shrink)
