The Contents of Perception

This chapter introduces and motivates the Null View about standard causally matching hallucinations. The Null View holds that these hallucinations fail to present any objects or sensible qualities, despite being dead ringers for perceptions of ordinary objects and their qualities. Motivation for the Null View comes from a neglected observation about perception-based thought, namely that perception can permit perception-based thought about a sensible quality even while misleading a subject about that quality. The chapter's other contribution is defensive. Most reject the (...) Null View on phenomenological or epistemic grounds. These objections to the Null View are sharpened and then undermined. (shrink)

In the philosophical literature, it is customary to think of perception as being assessable with respect to epistemic norms. E.g., the whole discussion around disjunctivism, which is now often considered to be the dominant, if not the default position in philosophy of perception, is, by and large, framed and motivated by epistemological concerns about truth and falsity. This book argues that perception is normative in another, more fundamental sense. Perception is governed by norms that Doyon calls perceptual, that is, immanent (...) to its own structure. This does not mean that perceptual norms are cut-off from external facts; it rather means that they are constitutive moments of our experience of these facts. Perceptual norms are, in that sense, constitutive or enabling norms in that they establish what perception is. To articulate this view, he draws in the repertoire of the phenomenological tradition, in the work of Edmund Husserl and Maurice Merleau-Ponty in particular. Like Kant, both phenomenologists were concerned with the question of the unity of experience and sought to identify the conditions of possibility for having a perception, which they conceive not as a mere sensible experience of the outer world, but as a continuous and meaningful experience of reality. Unlike Kant, however, neither phenomenologist immediately identified these conditions with cognition or epistemic criteria. For both phenomenologists, perception has its own standards, its own conditions of possibility. Perception obtains when it unfolds concordantly or coherently; and when the perceptual progression corresponds to or is in harmony with one's goal or interest, perception can also be said to be optimal. From the phenomenological point of view, concordance (Einstimmigkeit) and optimality (Optimalität) are the two basic perceptual norms governing over perceptual experience, and much of the book is devoted to clarifying their meaning and to address the philosophical consequences that follow from this insight.

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)

Contentful Moral Perceptualists such as Audi (2013), Lord (2018), McNaughton (1988), McBrayer (2010a, 2010b), Cowan (2014, 2015), and Werner (2016, 2018) claim that moral propositions can serve as the content of perception for moral subjects. However, in my original interpretation, recent critics of moral perceptualism, such as Faraci (2015), Väyrynen (2018), and Chudnoff (2015), subtly suggest that it is more reasonable to claim that moral propositions are the content of cognition rather than perception. Faraci, Väyrynen, and Chudnoff argue that the (...) so-called "moral perception" posited by Contentful Moral Perceptualists is actually dominated by dominative moral principles, representing a psychological state inferred from principles. Therefore, these critics believe that the so-called "moral perception" lacks the non-inferential characteristic of genuine perceptual experience and is not true perception. This paper will evaluate whether the "contentful moral perceptual model" can respond to the challenges posed by these critics. I will provide a preliminary defense for an affirmative answer. -/- Keywords: Moral Perception, Phenomenal Contrast Method, Perceptual Content, Phenomenal Experience, Non-Inferential Characteristics of Perception .

The debate over the metaphysics of sounds is about the nature of what we immediately auditorily perceive. There are good reasons to identify a sound with some kind of event. But what kind of event? I articulate and defend the _broad event view_ of sounds, on which a sound is identified with a broad event that produces and shapes an acoustic wave. I show that other views that identify a sound with some kind of event face serious problems. In particular, (...) Casati and Dokic’s (La philosophie du son, Editions Jacqueline Chambon, 1994 ) monadic event view fails to capture the full range of sounds, while O’Callaghan’s (Sounds: a philosophical theory, Oxford University Press, 2007 ; in: Nudds, O’Callaghan (eds) Sounds and perception: new philosophical essays, Oxford University Press, 2009 ; Oxford Stud Metaphys 5:247–270, 2010 ) relational event view identifies sounds with too narrow of an event, leading to problems capturing important differences between sounds and putting the perceiver at an unnecessary remove from the kind of broad events she typically cares about. The broad event view avoids these pitfalls. (shrink)

Both traditional and recent accounts of the beneficial and therapeutic effects of psychedelic experiences tie these effects to specifically epistemic changes, for example the enabling of spiritual or psychological insight, or disruption of problematic beliefs or thought patterns. While these alleged benefits have sometimes been thought to be facilitated by false or even delusional beliefs (e.g. Pollan 2015), recent philosophical discussion strikes a more optimistic tone, arguing that the epistemic risks involved with psychedelic drug use tend to be relatively benign (...) and outweighed by epistemic benefits (Letheby 2021). In this paper, we seek to nuance this picture by drawing attention to the crucial role played by social factors in determining the epistemic effects of psychedelic experiences. We argue that the very openness of mind and heightened sense of clarity and certainty that is often thought to facilitate the epistemic benefits of psychedelic drug use, also make the user more vulnerable to adverse epistemic influence from the social environment, to a degree not acknowledged in the current literature. Examining the epistemic influences of the social environment is thus important for understanding the necessary precautions of informed consent and overall safe drug use. (shrink)

Representationalists hold that perceptual experience is a conscious representational state with content, something which is accurate or inaccurate in certain conditions. The most common version of Representationalism takes perceptual content to be singular in the object-place and otherwise consisting of attribution of properties (Singularism/Attributionism). Schellenberg has recently developed a version on which perceptual content is singular even in the property-place in containing a de re mode of presentation of a property-instance (Particularism). In this paper, I show that Particularism faces a (...) version of the problem of the Unity of Perceptual Content. Namely, its supporters haven’t told us how objects can be bound together with property-instances into a content such that it represents them and has accuracy-conditions. Furthermore, I argue that Particularists face an in-principle obstacle in solving it. In contrast, Attributionists can solve the problem and that establishes their view as the only game in town.

Perception involves the processing of content or information about the world. In what form is this content represented? I argue that perception is widely compositional. The perceptual system represents many stimulus features (including shape, orientation, and motion) in terms of combinations of other features (such as shape parts, slant and tilt, common and residual motion vectors). But compositionality can take a variety of forms. The ways in which perceptual representations compose are markedly different from the ways in which sentences or (...) thoughts are thought to be composed. I suggest that the thesis that perception is compositional is not itself a concrete hypothesis with specific predictions; rather it affords a productive framework for developing and evaluating specific empirical hypotheses about the form and content of perceptual representations. The question is not just whether perception is compositional, but how. Answering this latter question can provide fundamental insights into perception. (shrink)

Traditional debates between semantic temporalists and eternalists appeal to the efficacy of temporal operators and the intuitive (in)validity of instances of temporal reasoning. In this paper, I argue that such debates are inconclusive at best and that under-explored arguments concerning perceptual experience, memory, and knowledge offer more productive means of advancing debates between temporalists and eternalists and rendering salient several significant potential costs and benefits of these views.

Tagging is the phenomenon in which regions of a picture, map, or diagram are annotated with words or other symbols, to provide descriptive information about a depicted object. The interpretive principles that govern tagged images are not well understood, due in part to the difficulty of integrating pictorial and linguistic semantic rules. Rather than directly combining these rules, I propose to use the framework of perspectival feature maps as an intermediary representation of content, in which the outputs of pictorial and (...) linguistic interpretation may be assimilated. The result is a simple and compositional semantics for tagged images. (shrink)

The notion of hyle seems problematic for a phenomenological foundation of experience. For this very reason, its completed invalidity was generally postulated. At the same time, there are many reflections in Husserlian writings that help us understand it better. This paper attempts to show how hyletic experience, by existing in the lived body, triggers in parallel rhythmic, vibrating, and sonorous experiences as bodily experiences. Sounds are experienced by the body before any reflections or conscious experiences of them. In this way, (...) the aporetical instance of hyletic data founds a proposal of resolution in the fundamental corporeal experience of sound. (shrink)

This article presents a dual purpose: to carefully consider objections against the existentialist conception of the content of visual experience and to develop and defend a version of it that avoids such objections, specifically addressing the so-called "problem of particularity." The main thesis is that the existential content of visual experience should be understood as relativized, being incomplete content (rather than classical, complete propositions), modeled as a function of the sextuple of the object, agent, time, place, causal relation, and world (...) to absolute values.

Perceptually secured knowledge consists of beliefs that amount to knowledge just because they are based on suitable perceptual states. Relationism about the ground of perceptually secured knowledge is the view that if a perceptual state can make a belief based on it amount to knowledge, then it can do that because it constitutes an appropriate kind of relational state, e.g., a state of perceptual acquaintance. I explore the prospects of both maintaining that some beliefs amount to perceptually secured knowledge and (...) developing a relationist account of their ground. (shrink)

An “inferentialist” semantic theory for some language L aims to account for the meanings of the sentences of L solely in terms of the inferential rules governing their use. A “hyper-inferentialist” theory admits into the semantics only “narrowly inferential” rules that normatively relate sentences of L to other sentences of L. A “strong inferentialist” theory also admits into the semantics “broadly inferential” rules that normatively relate perceptual states to sentences of L or sentences of L to intentional actions. It is (...) widely thought that only the latter of these two sorts of semantic theories is at all viable. I argue here that the opposite is so. Negatively, strong inferentialism is viciously circular: including rules into the semantic theory that relate perceptual states to sentences of the language requires us to appeal, in individuating those perceptual states, to the very meanings for which we are supposed to be inferentially accounting. Hyper-inferentialism does not face this problem because it does not appeal to any nonlinguistic states. Positively, though hyper-inferentialism is widely thought to be a theoretical non-starter, I argue here that it is a genuine theoretical possibility insofar as it essentially includes cross-perspectival inferences, inferences along the lines of the one from the sentences “The ball is in front of n,” “The ball is red,” and “The lighting is good” to the sentence “n sees that the ball is red.” I make the further exegetical claim that Robert Brandom, though unanimously taken to be a strong inferentialist, is in fact a hyper-inferentialist.

A prominent view holds that perception and memory are distinguished at least partly by their temporal orientation: Perception functions to represent the present, while memory functions to represent the past. Call this view perceptual presentism. This chapter critically examines perceptual presentism in light of contemporary perception science. I adduce evidence for three forms of perceptual sensitivity to the past: (i) shaping perception by past stimulus exposure, (ii) recruitment of mnemonic representations in perceptual processing, and (iii) perceptual representation of present objects (...) as possessing past properties. I argue that forms (i) and (ii) are consistent with perceptual presentism, while form (iii) poses a genuine threat to the view. While the empirical case for form (iii) remains inconclusive, I suggest that the most serious challenges to perceptual presentism derive from representations that integrate mnemonic and present-tensed elements in the performance of canonical perceptual functions, such as perceiving object continuity over time.

In recent work, Scott Soames (2010, 2013, 2015, 2019) and Peter Hanks (2011, 2013, 2015) have developed a theory of propositions on which these are constituted by complexes of intellectual acts. In this article, I adapt this type of theory to provide an account of perceptual content. After introducing terminology in section 1, I detail the approach proffered by Soames and Hanks in section 2, focusing on Hanks’s version. In section 3, I introduce a problem that these theories face, namely, (...) how to account for the unity among the relevant intellectual acts. Section 4 provides an answer to this problem of unity, while section 5 explicates the relation to Soames and Hanks. In section 6, I extend the model to a theory of the unity of experiential consciousness. Finally, in section 7, I apply the preceding considerations to debates about the nature of perceptual representation. The upshot will be that experiential unity is not simply a phenomenal feature of consciousness, but central to an account of the role perceptual representation plays in perceptual cognition.

The various themes explored in this superb collection of essays are organised around one thinker, John McDowell, and one central idea.

A large part of the contemporary literature on dehumanization is committed to three ideas: (a) dehumanization involves some degree of denial of humanness, (b) such denial is to be comprehended in mental terms, and (c) whatever exact mechanisms underlie the denial of humanness, they belong in the realm of post-perceptual processing. This chapter examines (c) and argues that the awareness of minds might belong to perceptual processing. This paves the way for the possibility that dehumanization might, at least in part, (...) be a perceptual phenomenon, such that dehumanizers visually perceive the dehumanized as exhibiting lesser-than-human minds. It is perhaps unsurprising that the first systematic investigations of dehumanization approached the phenomenon as linked to contexts of war, genocide, extreme hatred, and violence. One guiding hypothesis was that dehumanizers exclude the dehumanized from a moral community of human beings, implicitly conceptualized as displaying distinct individualities and being embedded in caring interpersonal relations. By comprehending the dehumanized as deindividuated entities to which moral norms and considerations of fairness do not apply (Opotow 1990), dehumanizers are able to disengage from moral restrictions and self-sanctions (Bandura 1999).

A number of authors have recently cited phenomenal effects of covert attention as a source of objection to representationalism. These authors maintain that covert attention brings about changes to phenomenology that cannot be explained by changes in representational content. This paper deals with two related issues that are central to this debate: (1) how attention interacts with representational content, and (2) how variations in the precision or determinacy of representational content should be incorporated into representationalist accounts of perceptual phenomenology. I (...) address these issues in the course of responding to several recent anti-representationalist arguments that have been advance by Ned Block. I argue that attention can increase the precision of range content and that this provides a basis for defusing both the concerns raised by Block and more general concerns related to covert attention. I conclude by situating my response with respect to analogous proposals that have been developed around the determination relation. (shrink)

The purpose of this essay is exegesis. I explicate Nicolas Malebranche's (1674, 1678, 1688, 1714) concept of intelligible extension. I begin by detailing how the concept matured throughout Malebranche's work, and the new functions it took on within his metaphysical system. I then examine Gustav Bergmann's “axiomatic” interpretation, as well as the criticism of it offered by Daise Radner. I argue that Radner's criticism of the interpretation is only partly successful; some of her objections can be met; others cannot. I (...) then develop a novel interpretation of the concept, given insights from this dispute. I call it the “programmatic interpretation.” I argue that this interpretation coheres well with Malebranche's famous Vision in God thesis, as well as many of his other commitments. I conclude by considering a certain pertinent objection to my proposal, summarizing the dialectic, and forcefully restating my case. (shrink)

Mystice videre: un modo particolare di vedere, sperimentato, lungo la storia dell’umanità, da coloro che hanno vissuto un’esperienza straordinaria di incontro con il sacro (termine che qui utilizzo nella sua accezione più ampia, di “ciò che è separato da” tutto ciò che è ordinario). Alludo ai mistici, ovviamente. Qualcuno, clinicamente parlando, potrebbe considerarli, con qualche ragione, individui patologici, ma sotto il profilo religioso si tratta di persone che hanno avuto la grazia di un incontro con il divino attraverso visioni profonde, (...) che, dalle tenebre del mistero, li hanno portati alla pienezza della luce interiore e hanno fatto sì che lo splendore che li ha illuminati si irradiasse all’esterno, dando un senso non solo al loro mondo interiore, ma anche al mondo che li circondava. Questo fecondo dinamismo tra “ciò che sta dentro” e “ciò che sta fuori” vale in tanti campi dell’esperienza umana, non solo nell’ambito del sacro, ma è in quest’ultimo che, elettivamente, l’attentio cordis determina l’irruzione nell’ombra di una luce che trasforma e permette di comprendere se stessi e l’intero cosmo.

Representationalists have routinely expressed skepticism about the idea that inflexible responses to stimuli are to be explained in representational terms. Representations are supposed to be more than just causal mediators in the chain of events stretching from stimulus to response, and it is difficult to see how the sensory states driving reflexes are doing more than playing the role of causal intermediaries. One popular strategy for distinguishing representations from mere causal mediators is to require that representations are decoupled from specific (...) stimulus conditions. I believe this requirement on representation is mistaken and at odds with explanatory practices in sensory ecology. Even when sensory states have the job of coordinating a specific output with a specific input, we can still find them doing the work of representations, carrying information needed for organisms to respond successfully to environmental conditions. We can uncover information at work by intervening specifically on the information conveyed by sensory states, leaving their causal role undisturbed. (shrink)

Daniel Dennett and others have suggested that qualia and introspectible phenomena do not exist. Dennett's account of consciousness, along with several related approaches, has been called illusionism by Keith Frankish. Frankish's analysis is helpful and provocative. As currently presented, however, his 'strong' version of illusionism suffers from several basic confusions, particularly regarding its relationship to eliminative materialism. This paper contrasts strong illusionism with an alternative that is easier to understand and more sharply focused -- fallibilist experiential realism, or, less technically, (...) modest realism. Fallibilist realism affirms the existence of experiential states that are commonly considered qualitative and phenomenal, but shares Frankish's agenda of thoroughly re-evaluating our judgments about such experiences. To illustrate the advantages of modest realism, I compare the ways illusionism and modest realism address two challenging puzzles: explaining how qualitative differences among sensory experiences could be constituted by differences among neural states, and explaining how neural states could constitute any conscious experiences whatsoever.

In this paper, I defend Non-Inferentialism about mental states, the view that we can perceive some mental states in a direct, non-inferential way. First, I discuss how the question of mental state perception is to be understood in light of recent debates in the philosophy of perception, and reconstruct Non-Inferentialism in a way that makes the question at hand—whether we can perceive mental states or not—scientifically tractable. Next, I motivate Non-Inferentialism by showing that under the assumption of the widely-accepted Principle (...) of Cognitive Economy, any account that treats mental state perception as an inferential process commits itself to an unrealistically inefficient picture of our cognitive architecture. Drawing on research in cognitive science, I will then show that my Non-Inferentialist view receives direct support by the available empirical evidence. I conclude that there is no psychologically relevant sense in which perception of mental states differs from paradigmatic cases of perception, such as the perception of ordinary objects. (shrink)
