When one visually hallucinates, the object of one’s hallucination is not before one’s eyes. On the standard view, that is because the object of hallucination does not exist, and so is not anywhere. Many different defenses of the standard view are on offer; each have problems. This paper defends the view that there is always an object of hallucination—a physical object, sometimes with spatiotemporally scattered parts.

This paper is a contribution to the philosophical debate on visual blur from a relationalist perspective. At the same time, it offers a methodological reflection on the adequacy of explanations of phenomenal similarities and differences among perceptual experiences. The debate on seeing blurrily has been shaped by two implicit assumptions concerning our explanations of differences and similarities between experiences of seeing blurrily and other experiences. I call those assumptions into question, and argue that we do not need to provide a (...) unified explanation of the character of blurry experiences for our account to be adequate. The diversity of blurry experiences supports a different, pluralist approach to explanations of how things appear to subjects. (shrink)

Visual perception is widely taken to present properties such as redness, roundness, and so on. This in turn might be thought to give rise to accuracy conditions for experience, and so content, regardless of which metaphysical view of perception one endorses. An influential version of this argument—Susanna Siegel’s ’Argument from Appearing’—aims to establish the existence of content as common ground between representational and relational views of perception. This goes against proponents of ‘austere’ relationalism who deny that content plays a substantive (...) role in philosophical explanations of conscious perceptual experience. Though Siegel’s argument purports to be neutral with respect to the metaphysics of perception, it relies upon an equivocation between the presentation of property-types and property-instances. Consequently, the argument begs the question against the austere relational view, and so fails to establish the desired conclusion. So while relationalists can and should allow that experiences have accuracy conditions, it does not follow from this that they have contents of any philosophically interesting or significant kind.

In a companion paper (Byrne and Green 2023) we disentangled the main characterizations of naïve realism and argued that illusions provide the best proving ground for naïve realism and its main rival, representationalism. According to naïve realism, illusions never involve perceptual error. We assessed two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and concluded that they fail. This paper considers another prominent attempt, from Craig French and Ian Phillips, and also sketches the case (...) for representationalism. (shrink)

In this chapter we will explore new avenues for developing and defending Naïve Realism (also known as Relationalism), understood as a thesis about the phenomenal character of experience. The core claim of Naive Realism is that ‘what it’s like’ for a subject who enjoys a normal, successful perceptual experience of her surroundings consists in her being directly consciously aware of mind-independent entities in her external environment. It is widely agreed that the strongest challenge to Naïve Realism comes from the alleged (...) possibility of total hallucinations, and the orthodox line of response has been to adopt Disjunctivism about perceptual experience. In this chapter, we will instead focus on an emerging alternative family of responses, which we’ll call ‘New Wave Relationalism’ (NWR). The core commitment of NWR is to reject the initial assumption that there can be total hallucinations that are both non-relational and subjectively indistinguishable from genuine perceptions. The primary aim for this chapter will be to explore and defend this broad NWR strategy for responding to the threat posed by hallucinations to Naïve Realism. We will argue that which specific version or species of NWR a Naïve Realist should adopt will depend on their background methodological and metaphysical commitments. (shrink)

Different authors offer subtly different characterizations of naïve realism. We disentangle the main ones and argue that illusions provide the best proving ground for naïve realism and its main rival, representationalism. According to naïve realism, illusions never involve per- ceptual error. We assess two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and conclude that they fail. Another lead- ing attempt is assessed in a companion paper, which also sketches an alternative representational account.

Brain activity determines which relations between objects in the environment are perceived as differences and similarities in colour, smell, sound, etc. According to selectionism, brain activity does not create those relations; it only selects which of them are perceptually available to the subject on a given occasion. In effect, selectionism entails that perceptual experience is diaphanous, i.e. that sameness and difference in the phenomenal character of experience is exhausted by sameness and difference in the perceived items. It has been argued (...) that diaphaneity is undermined by phenomenological considerations and empirical evidence. This paper considers five prominent arguments of this sort and shows that none of them succeeds. (shrink)

Confronted with the great variety one can find today in the work of those often labelled (either by themselves or by others) as “relationalists”, “naïve realists” or “disjunctivists”, one could be excused for thinking that relationalism has no common core, but is instead a constellation of views, which at best bear a kind of family resemblance to each other. We believe that this impression would be inaccurate. Relationalism is best thought of not as a constellation of loosely interrelated views, but (...) as a single wellspring of views, which has both a common core, and a variety of versions which differ from each other along two central axes of variation. In the first half of this introduction, we articulate this structure of relationalist views by constructing a common logical space for them. In the introduction’s second part, we use this logical space to introduce the various contributions this volume collects. (shrink)

I first show that a growing body of literature about the phenomenological and epistemic role of the structural features of experience can be recruited in favour of the view that absence experience is non‐veridical. Then I argue that such literature is in fact amenable to the view that absence experience is veridical if we rethink our conception of absence, and presence, itself.

Austere relationalism combines two claims. First, the phenomenal character of perception is at least partially constituted by the perceived items. Second, perception doesn’t consist in representing the perceived items as being a certain way. Recently, Daniel Kalpokas, Avner Baz, and Søren Overgaard have cast doubt on the ability of austere relationalism to account for the peculiar phenomenology of aspect-seeing. I show that this explanatory challenge can be met. Some of the claims made by the critics can be resisted, whereas other (...) can be accommodated into austere relationalism. Most notably, I argue that austere relationalists should acknowledge that aspect-seeing is enabled by unconscious perceptual judgment. This not only allows them to meet the challenge, but also provides the means to reconcile the apparently belief-independent phenomenology of aspect-seeing with the arguably indispensable role that concepts and recognition play in it.

Naïve realism is the view according to which perception is a non-representational relation of conscious awareness to mind-independent objects and properties. According to this approach, the phenomenal character of experience is constituted by just the objects, properties, or facts presented to the senses. In this article, I argue that such a conception of the phenomenology of experience faces a clear counter-example, i.e., the experience of seeing aspects. The discussion suggests that, to accommodating such a kind of experience, it must be (...) acknowledged that perception is, at least in part, representational. (shrink)

How can we have a sense of the presence of ordinary three-dimensional objects (e.g., an apple on my desk, a partially occluded cat behind a picket fence) when we are only presented with some parts of objects perceived from a particular egocentric viewpoint (e.g., the facing side of the apple, the unoccluded parts of the cat)? This paper presents and defends a novel answer to this question by incorporating insights from two prominent contemporary theories of perception, naïve realism and sensorimotor (...) theory. Naïve realism is the view that perception is fundamentally a matter of obtaining a relation of ‘acquaintance’ with some mind-independent entities (e.g., objects, properties, events). Sensorimotor theory holds that perception involves implicit practical understanding or ‘anticipation’ of the covariance between movements and sensory changes. I argue that perceptual presence is best accounted for in terms of the combination of our direct ‘acquaintance’ with some parts of perceived objects and sensorimotor ‘anticipations’ of how the objects would look different depending on some movements and actions.

When you hear music, you experience a repeating pulse that you naturally tap along to—you feel a beat. But you can feel a beat differently under sounds you hear as otherwise alike. Heard each way, things sound different. But, heard each way, nothing seems to change. So why do things sound different? I argue that, surprisingly, the usual theories of perception have no good answer. I then develop a view on which different ways of feeling a beat are different ways (...) of perceiving the same mind-independent features of things. On this view, feeling a beat is hearing sounds as organized within periods of time. And just as we can represent the same events using different calendars, we can perceive the same events using different beats. (shrink)

Perception plays a central and wide‐ranging role in the philosophy of Margaret Cavendish. In this paper, I argue that Cavendish holds a naïve realist theory of perception. The case draws on what Cavendish has to say about perceptual presentation, the role of sympathy in experience, the natures of hallucination and of illusion, and the individuation of kinds. While Cavendish takes perception to have representational content, I explain how this is consistent with naïve realism. In closing, I address challenges to the (...) interpretation, one of which turns on whether Cavendish allows for action at a distance. I argue that she does. (shrink)

This paper elaborates on an argument in my book *Perception*. It has two parts. In the first part, I argue against what I call "basic" naive realism, on the grounds that it fails to accommodate what I call "internal dependence" and it requires an empirically implausible theory of sensible properties. Then I turn Craig French and Ian Phillips’ modified naïve realism as set out in their recent paper "Austerity and Illusion". It accommodates internal dependence. But it may retain the empirically (...) implausible theory of sensible properties. And it faces other empirical problems. Representationalism about experiences avoids those problems and is to be preferred. (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.

Distant things look smaller, in a sense. Why? I argue that the reason is not that our experiences have a certain subject matter, or are about certain mind-independent things and features. Instead, distant things look smaller because of our way of perceiving them. I go on to offer a hypothesis about which specific way of perceiving explains why distant things look smaller.

A preview of my book *Perception*. Discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition of chapter summaries, (...) suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.

Bertrand Russell abandoned the notion of acquaintance in July 1918. What changes does this force in his account of the mind? This paper focuses on one puzzle of interpretation about this. In 1913, Russell offered an account of ‘egocentric particulars’, his term for indexicals and demonstratives. He argued that the fundamental objection to neutral monism was that it could not provide an adequate theory of these terms. In 1918, Russell now embraces a form of neutral monism, but he does not (...) return to the problem of indexicals until 1940 in his William James lectures. Is the account given in 1940 significantly different from the one given in 1913? What was the argument against neutral monism in 1913? Does Russell offer a new solution in 1940 or reject his earlier view as mistaken? The answers offered here are used to draw more general morals about the current debate concerning relational theories of sense perception. (shrink)

In this paper, I outline a disjunctivist proposal for understanding the intentionality of perceptions and hallucinations within a naïve realist framework. For the case of genuine perceptual experience, naïve realists can endorse a version of the view that their intentionality is phenomenally-grounded: perceptual experiences have intentionality in virtue of being relations of conscious acquaintance to aspects of the mind-independent environment. By contrast, hallucinations have intentionality dependently or derivatively, in virtue of their indiscriminability from, or similarity with respect to, perceptual experiences. (...) Within this proposal, naïve realists can allow that perceptions and hallucinations have a property in common – that of being intentionally directed at apparently mind-independent entities – whilst having wholly different metaphysical natures.

Different authors offer subtly different characterizations of naïve realism. We disentangle the main ones and argue that illusions provide the best proving ground for naïve realism and its main rival, representationalism. According to naïve realism, illusions never involve perceptual error. We assess two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and conclude that they fail. Another leading attempt is assessed in a companion paper, which also sketches an alternative representational account.

Naïve realists have yet to successfully discharge the problem of supersaturated hue, afterimage-experiences as of hued surfaces that are beyond-maximally saturated. The experiences are a problem for the view because supersaturation, qua property of external objects, is an impossible color property. Accordingly, the experiences cannot be handled in terms of their indiscriminability from perceptions of such surfaces, in the manner of Martin ( 2004 ). Nor can they be handled in terms of seen surfaces looking supersaturated, in the manner of (...) Kalderon ( 2011 ). This ramifies for every naïve realist view which grounds perceptual phenomenology in relation to perceptions, or to the qualities perceptions reveal. (shrink)

This thesis is about perceptual experience, its subjective character, and how it is essentially structured. It focuses specifically on how the nature of perception is shaped not only by our acquaintance with the world but also by the very structure of experience itself. My central claim is that perceptual consciousness incorporates different aspects, some of which constitute the very way in which experiences are organized, sustained, and structured. Over the course of this thesis, I develop and defend an original account (...) of the nature of perceptual experience by integrating naïve realism, a prominent contemporary Anglophone theory of perception, with insights and ideas from the Phenomenological tradition. In particular, I argue that there are fruitful grounds for combining naïve realism and a phenomenologically grounded account of the essential structural features of experience (‘minimal self’, ‘temporality’, ‘anticipation’). Naïve realism holds that perception is fundamentally a matter of being in direct contact with some mind-independent entities. Proponents of naïve realism often emphasize the ‘object-dependent’ nature of perception. The appeal to the structural features of experience offers us a promising way to delineate the oft-overlooked ‘subject-dependent’ nature of perception and capture the phenomenological richness of our conscious experiential life. This thesis offers a rich, phenomenologically informed account of the nature of perception which in turn places us in a better position to understand the nature of hallucination. The integration of naïve realism and the structural approach to consciousness I develop in this thesis yields a novel solution to the problem of hallucination: structural disjunctivism. According to this view, the ‘partially overlapping’ psychological nature of perception and hallucination is accounted for in terms of their structural similarities and differences. I seek to show how detailed analyses and reflections on the structures of perceptual experience pave the way to reconceive the phenomenological basis of naïve realism. (shrink)
