According to capacitism, to perceive is to employ personal-level, perceptual capacities. In a series of publications, Schellenberg (2016, 2018, 2019b, 2020) has argued that capacitism offers unified analyses of perceptual particularity, perceptual content, perceptual consciousness, perceptual evidence, and perceptual knowledge. “Capacities first” (2020: 715); appealing accounts of an impressive array of perceptual and epistemological phenomena will follow. We argue that, given the Schellenbergian way of individuating perceptual capacities which underpins the above analyses, perceiving an object does not require employing a (...) perceptual capacity which picks it out. Although each eye, used on its own, can suffice for perceiving objects in one’s environment, binocular vision allows one to see the same object(s) via both eyes, taking advantage of informational disparities registered by each eye. Yet in certain conditions it is possible to simultaneously see one object via the left eye and a distinct object via the right eye (at least when the inputs are sufficiently similar to prevent the onset of binocular rivalry). We argue that capacitism has trouble making sense of this. After surveying responses, we conclude that not all of the above phenomena can be unified under the capacitist framework. We then present a more nuanced, disjunctivist account of how capacities are individuated. While it may be illuminating to think of perceiving as the employment of perceptual capacities, this picture does not best favour a ‘common factor’ theory of perceptual content in the way existing presentations have envisaged.

Amodal completion is usually characterized as the representation of those parts of the perceived object that we get no sensory stimulation from. In the case of the visual sense modality, for example, amodal completion is the representation of occluded parts of objects we see. I argue that relationalism about perception, the view that perceptual experience is constituted by the relation to the perceived object, cannot give a coherent account of amodal completion. The relationalist has two options: construe the perceptual relation (...) as the relation to the entire perceived object or as the relation to the unoccluded parts of the perceived object. I argue that neither of these options are viable. (shrink)

Pitt :735–741, 2017) has argued that reductive representationalism entails an absurdity akin to the “paramechanical hypothesis” Ryle attributed to Descartes. This paper focuses on one version of reductive representationalism: the property-complex theory. We contend that at least insofar as the property-complex theory goes, Pitt is wrong. The result is not just a response to Pitt, but also a clarification of the aims and structure of the property-complex theory.

Various attempts have been made recently to bring Husserl into the contemporary analytic discussion on sensory illusion and hallucination. On the one hand, this has resulted in a renewed interest in what one might call a ‘phenomenology of sense-deception.’ On the other hand, it has generated contrasting—if not utterly incompatible—readings of Husserl’s own account of sense perception. The present study critically evaluates the contemporary discourse on illusion and hallucination, reassesses its proximity to Husserl’s reflection on sensory perception, and highlights the (...) philosophical limits and structural deficiencies of the current debate in light of some of Husserl’s insights. The analysis first provides a synopsis of the argumentative structures, aims, and assumptions informing the conjunctivism-disjunctivism debate. This assessment is then critically elaborated through the lens of Husserlian phenomenology in its historical and theoretical distance from the recent debate. Contrary to certain readings of Husserl, the reconstruction of some cardinal phenomenological themes provides all the elements necessary to dislocate his own account from the conjunctivism-disjunctivism dispute, by means of both a ‘global’ and a ‘local’ analysis, and both exegetically and theoretically. Most importantly, a ‘return’ to Husserl shows the philosophical untenability of the whole controversy as not only leaving untouched the core problem of perception but also altering some of its essential traits. This critique of the image of experience portrayed in the contemporary discussion is conducted through a phenomenological clarification of perception as a distinct ‘structure of rules’ of consciousness and, more specifically, by means of a descriptive analysis centered on the core notion of horizonal-intentionality.

Unconscious perceptions have recently become a focal point in the debate for and against naive realism. In this paper I defend the naive realist side. More specifically, I use an idea of Martin’s to develop a new version of naive realism—neuro-computational naive realism. I argue that neuro-computational naive realism offers a uniform treatment of both conscious and unconscious perceptions. I also argue that it accommodates the possibility of phenomenally different conscious perceptions of the same items, and that it can answer (...) a further challenge to naive realism raised by Berger and Nanay.

There are passages in Kant’s writings according to which empirical intuitions have to be (a) singular, (b) object-dependent, and (c) immediate. It has also been argued that empirical intuitions (d) are not truth-apt, and (e) need to provide the subject with a proof of the possibility of the cognized object. Having relied on one or another of the a-e constraints, the naïve realist readers of Kant have argued that it is not possible for empirical intuitions to be representations. Instead they (...) have argued for a relationalist reading of empirical intuitions in terms of an acquaintance relation between the subject and the intuited object. -/- For the sake of argument, I will grant the naïve realist reader of Kant that empirical intuitions should satisfy all the a-e constraints. Nevertheless, by incorporating these constraints, one by one, into a representationalist theory of empirical intuitions, I will show that not only doesn’t a naïve realist reading of empirical intuitions follow, but also that the naïve realist has hastily overlooked a range of perfectly representationalist readings of intuitions available to Kant and his representationalist allies. On the positive side, I will argue that there is an extra constraint on intuitions—i.e., that givenness does not require presence to consciousness—that directly goes against any naïve realist account of intuitions. (shrink)

I assume that there exists a general phenomenon, the phenomenon of the explanatory gap, surrounding consciousness, normativity, intentionality, and more. Explanatory gaps are often thought to foreclose reductive possibilities wherever they appear. In response, reductivists who grant the existence of these gaps have offered countless local solutions. But typically such reductivist responses have had a serious shortcoming: because they appeal to essentially domain-specific features, they cannot be fully generalized, and in this sense these responses have been not just local but (...) parochial. Here I do better. Taking for granted that the explanatory gap is a genuine phenomenon, I offer a fully general diagnosis that unifies these previously fragmented reductivist responses. (shrink)

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

Phenomenal particularism is the view that particular external objects are sometimes part of the phenomenal character of perceptual experience. It is a central part of naïve realist or relational views of perception. We consider a series of recent objections to phenomenal particularism and argue that naïve realism has the resources to block them. In particular, we show that these objections rest on assumptions about the nature of phenomenal character that the naïve realist will reject, and that they ignore the full (...) resources that naïve realism has to offer in explaining phenomenal character.

I aim to give a new account of picture perception: of the way our visual system functions when we see something in a picture. My argument relies on the functional distinction between the ventral and dorsal visual subsystems. I propose that it is constitutive of picture perception that our ventral subsystem attributes properties to the depicted scene, whereas our dorsal subsystem attributes properties to the picture surface. This duality elucidates Richard Wollheim’s concept of the “twofoldness” of our experience of pictures: (...) the “visual awareness not only of what is represented but also of the surface qualities of the representation.” I argue for the following four claims: (a) the depicted scene is represented by ventral perception, (b) the depicted scene is not represented by dorsal perception, (c) the picture surface is represented by dorsal perception, and (d) the picture surface is not necessarily represented by ventral perception.

My primary aim in this article is to provide a philosophical account of the unity of hallucinations, which can capture both perceptual hallucinations (which are subjectively indistinguishable from perceptions) and non-perceptual hallucinations (all others). Besides, I also mean to clarify further the division of labour and the nature of the collaboration between philosophy and the cognitive sciences. Assuming that the epistemic conception of hallucinations put forward by M. G. F. Martin and others is largely on the right track, I will (...) focus on two main tasks: (a) to provide a satisfactory phenomenology of the subjective character of perceptions and perceptual hallucinations and (b) to redress the philosophers’ neglect of non-perceptual hallucinations. More specifically, I intend to apply one of the central tenets of the epistemic conception—that hallucinations can and should be positively characterised in terms of their phenomenological connections to perceptions—to non-perceptual hallucinations as well. That is, I will try to show that we can positively specify the class of non-perceptual hallucinations by reference to the distinctive ways in which we first-personally experience them and perceptions in consciousness. The task of saying more about their underlying third-personal nature may then be left to the cognitive sciences. (shrink)

The main focus of acquaintance theorists has been the nature and mechanism of perceptual acquaintance with particulars. Generally, one’s view of perceptual acquaintance with general features has taken its bearings from one’s view of perceptual acquaintance with particulars. This has led to the glossing over of significant differences in the mechanisms of perceptual acquaintance with particulars and with general features. The difference in mechanisms suggests a difference in the sort of epistemic state at play in the two kinds of cases. (...) While the existence of such a difference might initially seem to spell trouble for acquaintance theorists, it can be made palatable by being traced back to the distinct basic functions concepts of particulars and of general features serve in thought.

This paper tries to meet the three basic constraints in the metaphysics of perception—that, following Schellenberg, I call here the particularity constraint, the indistinguishable constraint, and the phenomenological constraint—by putting forward a new combination of the two well-known contradictory views in this field: the relational view and the content view. Following other compatibilists, I do think that it is possible to reconcile the two views, recognizing that experience has both a relational and a representational dimension. However, in opposition to the (...) current ways of combining these two views, I reject the idea of gappy contents. Instead, my proposal is builds on Lewis’s famous semantic, according to which the content of sentences is best modeled as complex functions from context-index pairs to truth-values. In conformity with the content view, I want to suggest that perceptual experiences do represent complex properties or complex functions that are either veridical or falsidical of particulars in contexts and indexes. In this relativist framework, I can also accommodate the relational claim that our experience of particulars must be understood as a fundamental cognitive relation rather than as a representation. In this way, particulars also play a key role in individuating perceptual experiences. Two token experiences, e and e′, are different when one of the following conditions is met: first, if two different particulars, a and a′, are causally responsible for the token experiences e and e′, respectively, regardless of the time and location in which the perceptual experiences take place; second, if the same particular a, which is causally responsible for both e and e′, is either located in a different place or is in the same location but at a different time.

Object files are mental representations that enable perceptual systems to keep track of objects as numerically the same. How is their reference fixed? A prominent approach, championed by Zenon Pylyshyn and John Campbell, makes room for a non-satisfactional use of properties to fix reference. This maneuver has enabled them to reconcile a singularist view of reference with the intuition that properties must play a role in reference fixing. This paper examines Campbell’s influential defense of this strategy. After criticizing it, a (...) new approach is sketched. The alternative view introduces representational contents to explain perceptual individuation. After arguing that those contents are not satisfactional, it is concluded that there is room for a third view of reference fixing that does not fit into the singularist/descriptivist dichotomy. (shrink)

There are two very different ways of thinking about perception. According to the first one, perception is representational: it represents the world as being a certain way. According to the second, perception is a genuine relation between the perceiver and a token object. These two views are thought to be incompatible. My aim is to work out the least problematic version of the representational view of perception that preserves the most important considerations in favor of the relational view. According to (...) this version of representationalism, the properties represented in perception are tropes—abstract particulars that are logically incapable of being present in two distinct individuals at the same time. I call this view ‘trope representationalism’. (shrink)

Naïve realism is a theory of perception with great explanatory ambitions. It has been influentially argued that, in order to realize these explanatory ambitions, the naïve realist should say that any perception belongs to just one fundamental kind. I think, however, that adopting this commitment does not particularly help the naïve realist to realize her explanatory ambitions, and so is not warranted. This result is significant because once this commitment about fundamental kinds is relinquished, we see that it is possible (...) to develop some new and surprising forms of naïve realism—most notably, what I call pluralist naïve realism.

The paper discusses radical constructivism about episodic memory as developed by Kourken Michaelian under the name of “simulationism”, a view that equates episodic memory with mental time travel. An alternative, direct realist view is defended, which implies disjunctivism about the appearance of remembering. While admitting the importance of mental time travel as an underlying cognitive mechanism in episodic memory, as well as the prima facie reasonableness of the simulationist’s critique of disjunctivism, I formulate three arguments in defense of disjunctivism, which (...) thus appears to be a feasible alternative to radical constructivism. (shrink)

According to the phenomenological argument for disjunctivism, the reasons why we should prefer the disjunctive theory over its rivals is that (1) the disjunctive theory conforms the most to our pretheoretical or natural convictions about perception (what Michael Martin calls naïve realism), and (2) we should commit ourselves to naïve realism because it conforms the most to the phenomenology of the perceptual experience of objects. In this paper, I try to explain why is the phenomenal argument exceptionally strong argument for (...) disjunctivism and at the same time against sense-datum and intentional theories. Furthermore, I try to show that the disjunctivist’s explanation of hallucination (which is allegedly the weak point of the theory) is as plausible as its rivals’. (shrink)

In the present paper, I shall argue that disjunctively construed naïve realism about the nature of perceptual experiences succumbs to the empirically inspired causal argument. The causal argument highlights as a first step that local action necessitates the presence of a type-identical common kind of mental state shared by all perceptual experiences. In a second step, it sets out that the property of being a veridical perception cannot be a mental property. It results that the mental nature of perceptions must (...) be exhausted by the occurrence of inner sensory experiences that narrowly supervene on the perceiver. That is, empirical objects fail directly to determine the perceptual consciousness of the perceiver. The upshot is that not only naïve realism, but also certain further forms of direct realism have to be abandoned. (shrink)

Naïve Realism claims that veridical perceptual experiences essentially consist in genuine relations between perceivers and mind-independent objects and their features. The contemporary debate in the philosophy of perception has devoted little attention to assessing one of the main motivations to endorse Naïve Realism–namely, that it is the only view which articulates our ‘intuitive’ conception of perception. In this paper, I first clarify in which sense Naïve Realism is supposed to be ‘naïve’. In this respect, I argue that it is put (...) forward as the only view which can take our introspective knowledge of perception at face value, and I identify the two key features of such introspective knowledge. Second, I challenge the claim that one of these features-namely, that it seems as one could not be in the same perceptual state unless the putative objects of perception existed and were perceived–is introspectively evident. Consequently, I argue that a view of perceptual experience–such as Intentionalism–which denies that this feature is true of perception can still take introspection at face value. This undermines the claim that Naïve Realism is the only account which accommodates our intuitions on the nature of perception. (shrink)

Perceptual disjunctivism, as I regard it in this paper, is the view that veridical perceptions and hallucinations, while indistinguishable via introspection, are states of fundamentally different kinds. This fundamental difference can be spelled out in various ways. According to the view I will be concerned with, it is a fundamental difference in the personal-level structure of both states. Against this version of disjunctivism, I will raise a new challenge. It is a variant of what can be seen as the standard (...) challenge against disjunctivism: how to do justice to the indistinguishability of veridical perceptions and hallucinations. It differs, however, from common versions of this challenge in where it locates the potential incompatibility of disjunctivism with the relevant fact of indistinguishability. Commonly, it is the disjunctivist assumption of a fundamental difference between both kinds of states which is regarded as incompatible with the indistinguishability of these states. In contrast, I will suggest that if hallucinations and veridical perceptions differed in the way proposed by structural disjunctivism, this difference would induce a corresponding difference in the psychological processes of their introspection and that the assumption of such a difference in the manner of introspection is most likely incompatible with a properly formulated indistinguishability claim.

Stewart Cohen argues that basic knowledge is problematic, as it implies that subjects can acquire knowledge or justified beliefs about certain matters in ways that are supposedly too easy. Cohen raises two versions of the problem of easy knowledge, one involving the principle of closure and the other track-record style bootstrapping reasoning. In this paper I confront the problem of easy knowledge from the perspective of epistemological disjunctivism about perception. I argue that disjunctivism can do a better job than dogmatism (...) at responding to the version of the problem involving closure. I also argue that while disjunctivism would permit subjects to bootstrap their way to justified beliefs about the reliability of their perceptual powers, the disjunctivist can distinguish in a principled manner between this sort of bootstrapping and instances of it that we should agree are objectionable.

I argue against such "Relation Intentionalist" theories of consciousness as the higher-order thought and inner sense views on the grounds that they understand a subject's awareness of his or her phenomenal characters to be intentional, like seeming-seeing, rather than "direct", like seeing. The trouble with such views is that they reverse the order of explanation between phenomenal character and intentional awareness. A superior theory of consciousness, based on views expressed by Russell and Price, takes the relation of awareness to be (...) a nonintentional "acquaintance". (shrink)

This article is composed of three parts. In the first part of the article I take up a question raised by Susanna Siegel (Philosophical Review 115: 355–388, 2006a). Siegel has argued that subjects have the following anticipation: (PC) If S substantially changes her perspective on o, her visual phenomenology will change as a result of this change. She has left it an open question as to whether subjects anticipate a specific kind of change. I take up this question and answer (...) it in the affirmative. By appealing to a widely held view of perceptual content, the view that we represent ‘factual’ properties in perception, I argue that (PC) can be refined as follows: (PC’) If S substantially changes her perspective on o, her visual phenomenology will present different views of o’s factual properties. In the second part of the article I argue that (PC’) implies that there are cases in which normal perceivers have different perceptual content under identical viewing conditions. The differences in perceptual content are due to differences in the determinacy of visual anticipation. I draw the conclusion that perceptual content is rich in the sense that it includes a unique contribution from individual perceivers. In the final part of the article, I discuss some open issues regarding the way in which (PC’) relates to the personal/sub-personal distinction, empirical models, and the distinction between perception and cognition.
