Many philosophers hold that if an agent acts intentionally, she must know what she is doing. Although the scholarly consensus for many years was to reject the thesis in light of presumed counterexamples by Donald Davidson, several scholars have recently argued that attention to aspectual distinctions and the practical nature of this knowledge shows that these counterexamples fail. In this paper I defend a new objection against the thesis, one modelled after Timothy Williamson’s anti-luminosity argument. Since this argument relies on (...) general principles about the nature of knowledge rather than on intuitions about fringe cases, the recent responses that have been given to defuse the force of Davidson’s objection are silent against it. Moreover, the argument suggests that even weaker theses connecting practical entities with knowledge are also false. Recent defenders of the thesis that there is a necessary connection between knowledge and intentional action are motivated by the insight that this connection is non-accidental. I close with a positive proposal to account for the non-accidentality of this link without appeal to necessary connections by drawing an extended analogy between practical and perceptual knowledge.

In this paper I argue that Direct realism is less prone to internal incoherence as a theory of knowledge than alternative theories. The theory of Direct realism best grounds our capacity for cognition of the external world, whereas other epistemological theories claim to ground our capacity for cognition, but end in skepticism in the final analysis. I propose to show this contrast by bringing in different theories of a well-known Indirect realist, Bertrand Russell. Illustrating this point mainly through Russell makes (...) the approach purely historical in nature even when the paper includes a brief discussion of two theories in the current debate that support Direct realism.

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)

In this paper I argue for a theory of perception distinct both from classical sense-datum theories and from intentionalist theories, that is theories according to which one perceives external objects by dint of a relation with a propositional content. The alternative I propose completely rejects any representational element in perception. When one sees that an object has a property, the situation or state of affairs of its having that property is one's perception, so that the object and property are literally (...) part of one's mind. The most obvious objection to this view is that it embodies a rampant form of idealism. It is argued to the contrary, via consideration of the metaphysics of situations, that the theory is entirely consistent with a robustly realist view of the world. (shrink)

Disjunctivists (Hinton 1973, Snowdon 1990, Martin 2002, 2006) often motivate their approach to perceptual experience by appealing in part to the claim that in cases of veridical perception, the subject is directly in contact with the perceived object. When I perceive a table, for example, there is no table-like sense-impression that stands as an intermediary between the table and me. Nor am I related to the table as I am to a deer when I see its footprint in the snow. (...) I do not experience the table by experiencing some- thing else over and above the table and its facing surface. I see the facing surface of the table directly. (shrink)

According to the Dependency Theory, truth asymmetrically depends on the world, in the following sense: true propositions are true because the world makes them true. The Dependency Theory strikes many philosophers as incontrovertible, but in this paper I reject it. I begin by presenting a problem for the Dependency Theory. I then develop an alternative to the Dependency Theory which avoids that problem. This alternative is an immodest Identity Theory of Truth, and I end the paper by responding to Dodd’s (...) charge that immodest Identity Theories are incoherent. (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)

Relationalism maintains that perceptual experience involves, as part of its nature, a distinctive kind of conscious perceptual relation between a subject of experience and an object of experience. Together with the claim that perceptual experience is presentational, relationalism is widely believed to be a core aspect of the naive realist outlook on perception. This is a mistake. I argue that naive realism about perception can be upheld without a commitment to relationalism.

In the first part of the paper I try to explain why the disjunctive theory of perception can seem so counterintuitive by focusing on two of the standard arguments against the view-the argument from subjective indiscriminability and the causal argument. I suggest that by focusing on these arguments, and in particular the intuitions that lie behind them, we gain a clearer view of what the disjunctive theory is committed to and why. In light of this understanding, I then present an (...) argument for the disjunctive theory based on the claim that the content of experience is particular and not general. (shrink)

Defending a form of naïve realism about visual experiences is quite popular these days. Those naïve realists who I will be concerned with in this paper make a central claim about the subjective aspects of perceptual experiences. They argue that how it is with the perceiver subjectively when she sees worldly objects is literally determined by those objects. This way of thinking leads them to endorse a form of disjunctivism, according to which the fundamental psychological nature of seeings and hallucinations (...) is distinct. I will oppose their central claim by defending a version of the so-called ‘causal argument’, which dwells on ideas about causation and explanation in perception. The aim of this discussion is to highlight that the subjective aspects of perceptual experiences cannot be explained in naïve realist terms. Instead, it will be argued that one needs to appeal to a mental factor which does not involve worldly objects as constituents, and which is common to seeings and hallucinations. (shrink)

Fish proposes that we need to elucidate what 'disjunctivism' stands for, and he also proposes that it stands for the rejection of a principle about the nature of experience that he calls the decisiveness principle. The present paper argues that his first proposal is reasonable, but then argues, in Section II, that his positive suggestion does not draw the line between disjunctivism and non-disjunctivism in the right place. In Section III, it is argued that disjunctivism is a thesis about the (...) special nature of perceptual experience, and the thesis as elucidated here is then distinguished from and related to certain other ideas about perception, namely, direct realism and also McDowell's epistemological disjunctivism. (shrink)

Many philosophers believe that aesthetic testimony can provide aesthetic knowledge. This leaves us with the question: why does getting aesthetic knowledge by experience – by seeing a painting up close, or witnessing a performance first-hand – nevertheless seem superior to aesthetic testimony? I argue that it is due to differences in their epistemic value; in the diversity of epistemic goods each one provides. Aesthetic experience, or the experience of art or other aesthetic objects, affords multiple, distinctive epistemic goods whereas aesthetic (...) testimony affords less. In particular, it provides aesthetic knowledge of truths, a kind of propositional knowledge, as well as aesthetic knowledge of things, a kind of non-propositional knowledge. Although aesthetic experience is superior because it has more epistemic value, this doesn’t mean that aesthetic testimony provides weaker justification for aesthetic belief than aesthetic experience; the difference is evaluative, not normative. In this way, we can explain a key pessimistic intuition about aesthetic testimony – that it is inferior to aesthetic experience – whilst preserving the optimistic view that aesthetic testimony makes aesthetic knowledge available to others. The superior epistemic value of first-hand aesthetic experience is compatible with a number of important observations about aesthetic testimony, including the importance of aesthetic trust. (shrink)

Phenomenal character is the what-it's-likeness of subjective experience. I develop an ontology of phenomenal feel as process. My being in some phenomenal state R is the process of my instantiating R’s neurological correlate. The ontology explains why we have asymmetric epistemic access to phenomenal characters: the ontological ground for the subjective or first-personal stance is different from the ontological ground for the objective or third-personal stance. I end by situating my account in debates about physicalism.

This paper sets out a novel response to the ‘screening off problem’ for naïve realism. The aim is to resist the claim (which many naïve realists accept) that the kind of experience involved in hallucinating also occurs during perception, by arguing that there are causal constraints that must be met if an hallucinatory experience is to occur that are never met in perceptual cases. Notably, given this response, it turns out that, contra current orthodoxy, naïve realists need not adopt any (...) particular view about the psychological nature of hallucinatory experience to handle the screening off problem. Consequently, room opens up for naïve realists to endorse whatever theory of hallucinatory experience seems to best capture the distinctive nature of such episodes. (shrink)

It seems possible to see a star that no longer exists. Yet it also seems right to say that what no longer exists cannot be seen. We therefore face a puzzle, the traditional answer to which involves abandoning naïve realism in favour of a sense datum view. In this article, however, I offer a novel exploration of the puzzle within a naïve realist framework. As will emerge, the best option for naïve realists is to embrace an eternalist view of time, (...) and claim that in the relevant case, one sees a still existent star‐stage located somewhere in the distant past. (shrink)

A perceptual experience of a given object seems to make the object itself present to the perceiver’s mind. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) provides a better account of this phenomenological directness of perceptual experience than does the content view (the view that to perceive is to represent the world to be a certain way). But the naïve realist account of this phenomenology (...) has a conspicuous shortcoming: it explains the phenomenological directness of veridical perceptual experiences but not of hallucinations. Conversely, I maintain that a particular variety of the content view provides a unified account of the phenomenological directness of both veridical and hallucinatory experiences. If so, then contrary to what is often assumed, the phenomenological facts concerning perceptual experience are explained better by the content view than by naïve realism, and consequently, we have a compelling reason to prefer the content view to naïve realism. (shrink)

When you have a perceptual experience of a given physical object that object seems to be immediately present to you in a way it never does when you consciously think about or imagine it. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) can provide a satisfying account of this phenomenological directness of perceptual experience while the content view (the view that to perceive is to (...) represent the world to be a certain way) cannot. I argue that this claim is false. Specifically, I maintain that the only acceptable naïve realist account of the relevant phenomenology is circular and that the content view can provide a similar account. In addition, I maintain that a certain specific variety of the content view provides a non-circular and thus more satisfactory account of this phenomenology. If so, then contrary to what is commonly assumed there are powerful phenomenological grounds for preferring the content view to naïve realism. (shrink)

Naïve realism (also called ‘relationalism’ or ‘object view’) is becoming increasingly popular, but the specific outline of its commitments remains often underspecified by proponents and misunderstood by critics. Naïve realism is associated with two claims, both concerning genuine, veridical perceptual experience (where this excludes hallucinations). Constitutive Claim (CC): The phenomenal character of perception is (partly) constituted by the mind-independent objects in one’s surrounding and their properties. Relational Claim (RC): Perception is a relation to mind-independent objects in the environment and their (...) properties. Some philosophers use the two claims interchangeably while talking about naïve realism, while others use only one or the other, although they do not explicitly discuss if the other claim is also a core commitment of naïve realism, or if naïve realism can be held without the other claim. This raises the question of how RC and CC relate to one another, together with the most pressing question of what each claim ultimately commits one to. After discussing the shortcomings of alternative interpretations, I argue that naïve realism should be understood as committed to, first and foremost, RC. This should be understood as a claim about the phenomenal character of perception, rather than about its nature, structure or essence (whatever that means). CC, on the other hand, should be understood as a corollary of RC. This doesn’t only offer a better characterisation of how naïve realists understand phenomenal character: it also helps us understand how we can simultaneously claim that the object of perception is a constitutive element of perception, while also allowing for it to play a causal role in determining perception. (shrink)

I defend a view of the structure of visual property-awareness by considering the phenomenon of perceptual constancy. I argue that visual property-awareness is a three-place relation between a subject, a property, and a manner of presentation. Manners of presentation mediate our visual awareness of properties without being objects of visual awareness themselves. I provide criteria of identity for manners ofpresentation, and I argue that our ignorance of their intrinsic nature does not compromise the viability of a theory that employs them. (...) In closing, I argue that the proposed manners of presentation are consistent with key direct-realist claims about the structure of visual awareness. (shrink)

Recently representationalists have cited a phenomenon known as the transparency of experience in arguments against the qualia theory. Representationalists take transparency to support their theory and to work against the qualia theory. In this paper I argue that representationalist assessment of the philosophical importance of transparency is incorrect. The true beneficiary of transparency is another theory, naïve realism. Transparency militates against qualia and the representationalist theory of experience. I describe the transparency phenomenon, and I use my description to argue for (...) naïve realism and against representationalism and the qualia theory. I also examine the relationship between phenomenological study and phenomenal character, and discuss the results in connection with the argument from hallucination. (shrink)

In this paper, I argue for phenomenology, Husserlian phenomenology to be precise, as providing a solid paradigm on how to determine and assess hallucination. To be more explicit, in the context of my deliberations, I analyze Susanna Schellenberg’s arguments for “phenomenal” evidence and “factive” evidence, as regards her evidential theory of perception. To pinpoint the inadequacies raised in her account of (the hallucinating) Hallie and (the veridically perceiving) Percy sharing any kind of evidence, I propose Edmund Husserl’s epistemic fulfillment as (...) a detailed epistemological analysis of perception, which takes into consideration the latter’s phenomenological complexity. (shrink)

Two themes run through Wollheim’s work: the importance of history to the practice and appreciation of the arts, and the centrality of experience in appreciation. Prima facie, these are in tension. Reconciling them requires two steps. First, we should follow Wollheim in adopting a notion of experience on which features can be experienced even if we must have experience-independent access to the fact that the work exhibits them. Second, we need to state what makes a particular experience appropriate to the (...) work. What does so? An obvious answer is that the experience reflects the work’s nature. Wollheim toyed with a more ambitious line, one linking the appropriate experience to our abilities to discriminate instances of the property appreciated. He allowed that having the right experience might require knowledge of the work, and thus that that experience need not be born of the ability to discriminate the property appreciated. But he seems to have held that the appropriate experience must engender that ability, at least against the background of those actual items that might be confused with instances of the property. I argue that Wollheim’s answer is less appealing than the obvious one. (shrink)

I interpret the anti-idealist manoeuverings of the second half of Moore's 'The refutation of idealism', material as widely cited for its discussion of 'transparency' and 'diaphanousness' as it is deeply obscure. The centerpiece of these manoeuverings is a phenomenological argument for a relational view of perceptual phenomenal character, on which, roughly, 'that which makes the sensation of blue a mental fact' is a non-intentional relation of conscious awareness, a view close to the opposite of the most characteristic contemporary view going (...) under the transparency rubric. The discussion of transparency and diaphanousness is a sidelight, its principal purpose to shore up the main line of argumentation against criticism; in those passages all Moore argues is that the relation of conscious awareness is not transparent, while acknowledging that it can seem to be. (shrink)

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)

If you want to understand McDowell's spatial metaphors when he talks about perceptual knowledge, place him side-by-side with Dretske on perceptual knowledge. Though McDowell shows no evidence of reading Dretske's writings on knowledge from the late 1960s onwards (McDowell mentions "Epistemic Operators" once in passing), McDowell gives the same four arguments as Dretske for the conclusion that knowledge requires "conclusive" reasons that rule of the possibility of mistake. Despite various differences, we think it is best to read McDowell as re-discovering (...) Dretske on perceptual knowledge. Since Dretske is easy to understand, all of McDowell's metaphors become easy to understand. But what about McDowell's disjunctivism? Turns out McDowell is not an ontological disjunctivist, and his epistemological disjunctivism is really just the banal point that some perceptual experiences provide conclusive reasons for perceptual belief and some do not. Perceptual experiences are either conclusive or inconclusive. Dretske would agree. (shrink)

Naïve Realists think that the ordinary mind-independent objects that we perceive are constitutive of the character of experience. Some understand this in terms of the idea that experience is diaphanous: that the conscious character of a perceptual experience is entirely constituted by its objects. My main goal here is to argue that Naïve Realists should reject this, but I’ll also highlight some suggestions as to how Naïve Realism might be developed in a non-diaphanous direction.

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.

One increasingly popular view in the philosophy of perception isexternalismabout sensible qualities, according to which sensible qualities such as colors, smells, tastes, and textures are features, not of our minds, but of mind-independent, external objects in the world. The primary motivation for this view is that perceptual experience seems to betransparent—that is, when we attend to sensible qualities, it seems like what we are attending to are features of external objects, not our own minds. Most (if not all) externalists are (...) either naïve realists or externalist representationalists. However, in this article, I argue that those who are moved by the primary motivation for externalism should instead be sense-datum theorists, for externalists’ primary motivation supports the sense-datum theory, not their actually favored views. I argue that externalists should focus on different motivations, get new ones, or become sense-datum theorists. (shrink)

It is now common to distinguish Metaphysical from Epistemological Disjunctivism. It is equally common to suggest that it is at least not obvious that the latter requires a commitment to the former: at the very least, a suitable bridge principle will need to be identified which takes one from the latter to the former. This paper identifies a plausible-looking bridge principle that takes one from the version of Epistemological Disjunctivism defended by John McDowell and Duncan Pritchard, which I label Reflective (...) Epistemological Disjunctivism, or (RED), to Metaphysical Disjunctivism. Moreover, it identifies a modification the proponent of (RED) could, and should, make to the Internalist component of their theory, and argues that the commitment to Metaphysical Disjunctivism remains, even if such a modification is made. The upshot is that the commitment to Metaphysical Disjunctivism on the part of (RED) is shown to be particularly robust. (shrink)

Reflection on cases involving the occurrence of various types of perceptual activity suggests that the phenomenal character of perceptual experience can be partly determined by agential factors. I discuss the significance of these kinds of case for the dispute about phenomenal character that is at the core of recent philosophy of perception. I then go on to sketch an account of how active and passive elements of phenomenal character are related to one another in activities like watching and looking at (...) things. (shrink)

The paper presents a new theory of perceptual demonstrative thought, the property-dependent theory. It argues that the theory is superior to both the object-dependent theory (Evans, McDowell) and the object-independent theory (Burge).

It has been claimed that naïve realism predicts phenomenological similarities where there are none and, thereby, mischaracterises the phenomenal character of perceptual experience. If true, this undercuts a key motivation for the view. Here, we defend naïve realism against this charge, proposing that such arguments fail (three times over). In so doing, we highlight a more general problem with critiques of naïve realism that target the purported phenomenological predictions of the view. The problem is: naïve realism, broadly construed, doesn’t make (...) phenomenological predictions of the required sort. So, as a result, opponents must resign themselves to attacking specific incarnations of naïve realism, or approach matters quite differently. (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.

Joint attention customarily refers to the coordinated focus of attention between two or more individuals on a common object or event, where it is mutually “open” to all attenders that they are so engaged. We identify two broad approaches to analyse joint attention, one in terms of cognitive notions like common knowledge and common awareness, and one according to which joint attention is fundamentally a primitive phenomenon of sensory experience. John Campbell’s relational theory is a prominent representative of the latter (...) approach, and the main focus of this paper. We argue that Campbell’s theory is problematic for a variety of reasons, through which runs a common thread: most of the problems that the theory is faced with arise from the relational view of perception that he endorses, and, more generally, they suggest that perceptual experience is not sufficient for an analysis of joint attention.

Naïve realists traditionally reject the time lag argument by replying that we can be in a direct visual perceptual relation to temporally distant facts or objects. I first show that this answer entails that some visual perceptions—i.e., those that are direct relation between us and an external material object that has visually changed, or ceased to exist, during the time lag—should also count as illusions and hallucinations, respectively. I then examine the possible attempts by the naïve realist to tell such (...) perceptions apart from illusions and hallucinations, and after showing the inadequacy of the answers relying on a mere counterfactual or causal criterion, I explain why the problem is solved by introducing a view of visual perception as temporally extended into the past of objects and, in particular, as consisting in the whole causal chain of events or states of affairs going from external material objectxto subjectS. But this solution is not immune from defects for the naïve realist. I show that this view of perception raises a number of significant concerns, hence leaving the issue of the time lag problem still open for naïve realism. (shrink)

Is there good reason to worry about celebrity involvement in democratic politics? The rise of celebrity politicians such as Donald Trump and Vladimir Zelensky has led political theorists and commentators to worry that the role of expertise in democratic politics has been undermined. According to one recent critique, celebrities possess a significant degree of epistemic power that is unconnected to appropriate expertise. This presents a problem both for deliberative and epistemic theories of democratic legitimacy, which ignore this form of power, (...) and for real existing democracies attempting to meet the standards of legitimacy set out by these theories. But do these critiques apply to democratic elitism? In this paper, we argue that recognition of celebrity epistemic power in fact represents a valuable resource for supporting the legitimacy and practice of democratic elitism, though these benefits do come with certain risks to which elite theories are particularly vulnerable.

The debate between relationalism and representationalism in the philosophy of perception seems to have come to a standstill where opponents radically disagree on methodological principles or fundamental assumptions. According to Fish (this volume) this is because, not unlike Kuhnian scientific paradigms, the debate displays some elements of incommensurability. This diagnosis makes advancing the debate impossible. I argue that what is hindering progress is not a clash of research programmes, but a series of misunderstandings that can be avoided by disentangling the (...) different questions each theory is invested in and by making explicit the hidden assumptions at play in the debate. One such central assumption is what I call the Superficiality Constraint. This is the idea that the phenomenal character of experience is superficial with respect to introspection. I argue that we can make progress in the debate by assessing to what extent and at what cost relationalism can accommodate this constraint. (shrink)

Many contemporary theorists charge that naïve realists are incapable of accounting for illusions. Various sophisticated proposals have been ventured to meet this charge. Here, we take a different approach and dispute whether the naïve realist owes any distinctive account of illusion. To this end, we begin with a simple, naïve account of veridical perception. We then examine the case that this account cannot be extended to illusions. By reconstructing an explicit version of this argument, we show that it depends critically (...) on the contention that perceptual experience is diaphanous, or more minimally and precisely, that there can be no difference in phenomenal properties between two experiences without a difference in the scenes presented in those experiences. Finding no good reason to accept this claim, we develop and defend a simple, naïve account of both veridical perception and illusion, here dubbed Simple, Austere Naïve Realism. (shrink)

The thesis is intended to contribute to the growing understanding of the indispensable role played by phenomenal consciousness in human cognition, and specifically in making our concepts of the external world available. The focus falls on so called observational concepts, a type of rudimentary, perceptually-based objective concepts in our repertoire — picking out manifest properties such as colors and shapes. A theory of such concepts gets provided, and, consequently, the exact role that perceptual consciousness plays in making concepts of this (...) sort available gets settled. In the first half of the thesis, observational concepts get construed as a special type of recognitional concepts. On an analogy with perceptual demonstratives, having such concepts would involve having non-trivial knowledge of their reference. The experiential basis of such concepts would, among other things, provide for such constitutive knowledge. The theoretical background relevant to the hypothesis gets provided in the first chapter. A defence of the hypothesis follows in the second. In the second half of the thesis, care is taken to distinguish among two ways in which the constitutive knowledge of the reference of an observational concept could be fleshed out. In the third chapter, perceptual experience is shown to provide the basis both for knowledge of observational properties by acquaintance, and for knowledge of the essence of such properties — provided that knowledge of essence gets construed in the right, modest way. It might be natural to take knowledge by acquaintance to be the sort relevant to observational concept possession, especially given that in the case of perceptual demonstratives this is the role likely played by experience. However, this initial impression proves to be mistaken. The constitutive knowledge of the referent of an observational concept turns out to consist in the capacity to determine a priori the essence of the respective property. To show this, an argument gets provided in the penultimate fourth chapter, based on the key role played by experiences of instances of observational properties in optimal viewing conditions in enabling the possession of the respective observational concept.

Relationalism claims that the phenomenal character of perception is constituted by the obtaining of a non-representational psychological relation to mind-independent objects. Although relationalism provides what seems to be the most straightforward and intuitive account of how experience strikes us introspectively, it is very often believed that the argument from hallucination shows that the view is untenable. The aim of this thesis is to defend relationalism against the argument from hallucination. The argument claims that the phenomenal character of hallucination and perception (...) deserves the same account, and that relationalism cannot be true for hallucinations, therefore relationalism must be rejected. This argument relies on the Indiscriminability Principle, the claim that two experiences that are introspectively indiscriminable from each other have the same phenomenal character. Before assessing the plausibility of this principle, I first consider and dismiss versions of the argument which wouldn’t depend on IND. Although widely accepted, no satisfactory support for IND has been presented yet. In this thesis I argue that defending IND requires that we understand the notion of ‘indiscriminability’ employed in IND in an impersonal sense. I then identify what underwrites IND: the intuition that, in virtue of its superficiality, the nature of a phenomenal character must be accessible through introspection, together with the claim that it is not possible to deny IND without denying the superficiality of phenomenal characters too. I argue that the relationalist can deny IND while preserving the superficiality of phenomenal characters. This can be done by adopting a negative view of hallucination and an account of introspection whereby the phenomenal character doesn’t exist independently of one’s introspective awareness of it and where having introspective access to our experience depends on our perceptual access to the world.
