Over the centuries the nature of erroneous perception has been thoroughly discussed by Indian philosophers of nearly every school. This text aims to pursue important issues in the discussion of perceptual error. It sheds light on why Indian philosophers devoted so much attention to the problem of erroneous perception but also on why the ontological status of the object of error became such an important issue. The result is a history of the interactions among rival theories of (...) perceptual error. (shrink)

Perception of the external world is an essential part of the animal (including human) life, both as a source of knowledge and as a way to survive. Medieval authors accepted this view, and despite general concerns about the reliability of the senses in the acquisition of certain and objective knowledge, they thought that for the most part our perceptual system gets things right when it comes to the perceptual features of things—but not always. Our article focuses on thirteenth- (...) and fourteenth-century philosophical discussions of illusions and other types of perceptual errors. Reception of incorrect information, misjudgments concerning perceptual objects, the binding problem, and similar cases that explain perceptual errors will be analyzed. We discuss what might be called medieval Aristotelian/Avicennian theories of perception and the internal senses (drawing mainly from Albertus Magnus and Thomas Aquinas), as well as the so-called perspectivist accounts of perception, especially that by Alhacen. Finally, we take up a debate between Peter Auriol and his critics, which contains elements that can be seen as precursors of later skeptical worries. The concern here is that, just like in contemporary discussions leading to disjunctivism, the absence of a secure way to distinguish between veridical and non-veridical perception leads to a general worry about the reliability of our experience of the world.

Claude Romano and Andrea Staiti have recently discussed Husserl’s account of perception in relation to debates in current analytic philosophy between so-called “conjunctivists” and “disjunctivists”. Romano and Staiti offer strikingly different accounts of the nature of illusion and hallucination, and opposing readings of Husserl. Romano thinks hallucinations and illusions are fleeting, fragile phenomena, while Staiti claims they are inherently retrospective phenomena. Romano reads Husserl as being committed to a form of conjunctivism that Romano rejects in favour of a version of (...) disjunctivism. Staiti, by contrast, claims that, from a Husserlian viewpoint, conjunctivism and disjunctivism are equally untenable. I suggest that both Romano and Staiti offer implausible accounts of illusions and hallucinations, and deliver premature verdicts on Husserl in relation to the analytic debates on perception.

This paper argues that Locke cannot provide a satisfactory account of perceptual error.

Aristotle sometimes claims that the perception of special perceptibles by their proper sense is unerring. This claim is striking, since it might seem that we quite often misperceive things like colours, sounds and smells. Aristotle also claims that the perception of common perceptibles is more prone to error than the perception of special perceptibles. This is puzzling in its own right, and also places constraints on the interpretation of. I argue that reading Alexander of Aphrodisias on perceptual (...) class='Hi'>error can help to make good sense of both of Aristotle’s claims. (shrink)

Locke claims that we have sensitive knowledge of the external world, in virtue of the fact that simple ideas are real, true, and adequate. However, despite his dismissive remarks about Cartesian external-world skepticism, Locke gives us little to go on as to how knowledge of the external world survives the fact of perceptual error, or even how perceptual error is possible. I argue that Locke has an in-principle problem explaining perceptual error.

My paper has three parts. First I will outline the act/object theory of perceptual experience and its commitments to (a) a relational view of experience and (b) a view of phenomenal character according to which it is constituted by the character of the objects of experience. I present the traditional adverbial response to this, in which experience is not to be understood as a relation to some object, but as a way of sensing. In the second part I argue (...) that acceptance of (a) is independent of acceptance of (b). I then present a modified adverbialism that presents experience as relational in nature but whose character is nevertheless to be explained in terms of the way in which one senses an object. Finally, I will offer an explanation of how a naïve realist about experience can adopt this modified adverbialism and in so doing accommodate the possibility of perceptual error. (shrink)

Christopher Hill's Perceptual experience is a must‐read for philosophers of mind and cognitive science. Here I consider Hill's representationalist account of spatial perception. I distinguish two theses defended in the book. The first is that perceptual experience does not represent the enduring, intrinsic properties of objects, such as intrinsic shape or size. The second is that perceptual experience does represent certain viewpoint‐dependent properties of objects—namely, Thouless properties. I argue that Hill's arguments do not establish the first thesis, (...) and then I raise questions about the Thouless‐property view and its role in Hill's defense of representationalism. (shrink)

A process model of concept development is proposed as a means of understanding the mind body problem. This paper reviews some definitions and views of mind, reiterates Karl Popper's description of the development of scientific as compared to essentialist methods of concept definition, compares the development of physical and psychological concepts, notes an apparent illogic of the mind and body issue, and discusses a range of psychological theories in relation to this process model, that is, Skinner's behavior view, to Pribram's (...) presentation of cognitive theory, to Epstein's theory of the self concept, and to existentialistic views. In terms of meaning and usefulness, mind and behavioral concepts appear to evolve in the same manner. (shrink)

Epistemological realists have long struggled to explain perceptual error without introducing a tertium quid between perceivers and physical objects. Two leading realist philosophers, Thomas Reid and Everett Hall, agreed in denying that mental entities are the immediate objects of perceptions of the external world, but each relied upon strange metaphysical entities of his own in the construction of a realist philosophy of perception. Reid added ‘visible figures’ to sensory impressions and specific sorts of mental events, while Hall utilized (...) an array of ways that he maintained properties may participate in the world. This paper assesses each realist's attempt to explain perceptual relativity and illusion without contradicting either the science of his time or the structure of common sense. (shrink)

Despite the fact that many of our beliefs are justified by perceptual experience, there is relatively little exploration of the connections between epistemic justification and perceptual content. This is unfortunate since it seems likely that some views of justification will require particular views of content, and the package of the two might be quite a bit less attractive than either view considered alone. I will argue that this is the case for epistemic internalism. In particular, epistemic internalism requires (...) a view of perceptual content that results in an error theory of perception. This, in turn, hobbles the internalist’s account of perceptual justification. While there are various stages along the way at which one can resist the argument, each one will involve significant commitments that highlight heretofore unacknowledged connections between justification and content. Even if the internalist is willing to make these moves and resist the argument, the argument reveals a novel way for the epistemic externalist to resist one of internalism’s main arguments. (shrink)

A period of exposure to trains of simultaneous but spatially offset auditory and visual stimuli can induce a temporary shift in the perception of sound location. This phenomenon, known as the 'ventriloquist aftereffect', reflects a realignment of auditory and visual spatial representations such that they approach perceptual alignment despite their physical spatial discordance. Such dynamic changes to sensory representations are likely to underlie the brain's ability to accommodate inter-sensory discordance produced by sensory errors (particularly in sound localization) and variability (...) in sensory transduction. It is currently unknown, however, whether these plastic changes induced by adaptation to spatially disparate inputs occurs automatically or whether they are dependent on selectively attending to the visual or auditory stimuli. Here, we demonstrate that robust auditory spatial aftereffects can be induced even in the presence of a competing visual stimulus. Importantly, we found that when attention is directed to the competing stimuli, the pattern of aftereffects is altered. These results indicate that attention can modulate the ventriloquist aftereffect. © 2010 Elsevier B.V. (shrink)

Perceptions "present" objects as red, as round, etc.-- in general as possessing some property. This is the "perceptual content" of the title, And the article attempts to answer the following question: what is a materialistically adequate basis for assigning content to what are, after all, neurophysiological states of biological organisms? The thesis is that a state is a perception that presents its object as "F" if the "biological function" of the state is to detect the presence of objects that (...) are "F". The theory contrasts with causal/informational theories, and with internalist theories, for example those which assign content on the basis of introspected feel. Its advantages are that it permits perceptual error while at the same time allowing content to be expressed in terms of external properties. The argument of the paper is illustrated throughout by examples from biology and computational psychology. (shrink)

Causal theories of perception typically have problems in explaining deviant causal chains. They also have difficulty with other unusual putative cases of perception involving prosthetic aids, defective perception, scientifically extended cases of perception, and so on. But I show how a more adequate reflexive causal theory, in which objects or properties X cause a perceiver to acquire X-related dispositions toward that very same item X, can provide a plausible and principled perceptual explanation of all of these kinds of cases. (...) A critical discussion of David Lewis's perceptual descriptivist views is also provided, including a defense of the logical possibility of systematic misperception or perceptual error for a perceiver, in spite of its empirical improbability.

Carter and Pritchard (2016) and Pritchard (2010, 2012, 2016) have tried to reconcile the intuition that perceptual knowledge requires only limited discriminatory abilities with the closure principle. To this end, they have introduced two theoretical innovations: a contrast between two ways of introducing error-possibilities and a distinction between discriminating and favoring evidence. I argue that their solution faces the “sufficiency problem”: it is unclear whether the evidence that is normally available to adult humans is sufficient to retain knowledge (...) of the entailing proposition and come to know the entailed proposition. I submit that, on either infallibilist or fallibilist views of evidence, Carter and Pritchard have set the bar for deductive knowledge too low. At the end, I offer an alternative solution. I suggest that the knowledge-retention condition of the closure principle is not satisfied in zebra-like scenarios. (shrink)

This book explores the important yet neglected relationship between the philosophy of time and the temporal structure of perceptual experience. It examines how time structures perceptual experience and, through that structuring, the ways in which time makes perceptual experience trustworthy or erroneous. -/- Sean Power argues that our understanding of time can determine our understanding of perceptual experience in relation to perceptual structure and perceptual error. He examines the general conditions under which an (...) experience may be sorted into different kinds of error such as illusions, hallucinations, and anosognosia. Power also argues that some theories of time are better than others at giving an account of the structure and errors of perceptual experience. He makes the case that tenseless theory and eternalism more closely correspond to experience than tense theory and presentism. Finally, the book includes a discussion of the perceptual experience of space and how tenseless theory and eternalism can better support the problematic theory of naïve realism. -/- Philosophy of Time and Perceptual Experience originally illustrates how the metaphysics of time can be usefully applied to thinking about experience in general. It will appeal to those interested in the philosophy of time and debates about the trustworthiness of experience. (shrink)

This thesis offers a fresh interpretation and defense of epistemological disjunctivism about perceptual knowledge. I adopt a multilevel approach according to which perceptual knowledge on one level can enjoy factive rational support provided by perceptual knowledge of the same proposition on a different level. Here I invoke a distinction Ernest Sosa draws between ‘judgmental’ and ‘merely functional’ belief to articulate what I call the bifurcated conception of perceptual knowledge. The view that results is a form of (...) epistemological disjunctivism about perceptual knowledge specifically at the higher judgmental level, layered over a straightforward externalism about perceptual knowledge at the lower merely functional level. The first chapter orients the reader to epistemological disjunctivism— with particular emphasis on the ‘reflective epistemological disjunctivism’ defended by Duncan Pritchard with inspiration from John McDowell. Here I review the arguments for thinking such a proposal true, as well as highlight some problems and three emerging challenges for the view: what I call the internalist challenge, the new access challenge, and the ‘new evil genius’ challenge. These challenges largely inspire the chapters to follow. In the second chapter I present the positive proposal: a fresh interpretation of epistemological disjunctivism in terms of perceptual knowledge at the specifically judgmental level. I argue that this is a modification that epistemological disjunctivists should adopt since it inoculates their view against the internalist challenge: the challenge of explaining why perception should provide one with knowledge by providing one with motivating reasons for belief. In the third chapter I motivate the view further in connection with the more familiar ‘basis problem’ for epistemological disjunctivism. I argue that this approach supports a unique strategy for solving that problem: one that is consistent both with what is known as ‘the entailment’ thesis and the thought that we can reduce perceptual knowledge to a kind of rationally supported belief. In the fourth chapter I move to playing defense. I defend the proposal against the so-called ‘new evil genius’ challenge. This is the challenge to explain why subjects in pairs of ‘good’ and ‘bad’ cases can seem equally justified for sustaining their perceptual beliefs. I argue that what we are being sensitive to here, rather, is the fact that both subjects can be equally epistemically responsible and/or reasonable for believing what they do. Before concluding this chapter I also offer an error theory. In the fifth chapter I defend the proposal against the new access challenges raised in chapter one. These alleged challenges for epistemological disjunctivism arise specifically for versions of reflective epistemological disjunctivism that hold that one’s rational support for perceptual beliefs is not only factive but reflectively accessible as well. Rather than address the challenges head on, I try to dislodge the thought they depend upon—viz., that one’s factive rational support for perceptual beliefs is reflectively accessible to the subject. Here I argue that the reflective accessibility of one’s factive rational support is actually a wheel turning idly in the debate with the underdetermination-based radical sceptic—so that we can simply drop it without consequence. The result is an epistemological disjunctivism that is immune to access problems. I then offer a final summary and conclude. At the end of this thesis I have attached an appendix, which is an excursion into religious epistemology and an exploration of a form of religious epistemological disjunctivism. Here I apply the epistemological disjunctivist insight to the case of religious perception in order to defend the idea that one can offer independent rational support for theistic belief by appealing to religious beliefs that are justified on the basis of religious experiences. This appendix chapter is in keeping with the general spirit of the thesis insofar as it seeks to developed epistemological disjunctivism in new and fruitful directions. (shrink)

In his paper, MacKay reviews his Node Structure theory of error detection, but precedes it with a critical discussion of the Perceptual Loop theory of self-monitoring proposed in Levelt . The present commentary is concerned with this latter critique and shows that there are more than casual problems with MacKay's argumentation.

Although current debates in epistemology and philosophy of mind show a renewed interest in perceptual illusions, there is no systematic work in the philosophy of perception and in the psychology of perception with respect to the concept of illusion and the relation between illusion and error. This book aims to fill that gap.

The distinction between true belief and knowledge is one of the most fundamental in philosophy, and a remarkable effort has been dedicated to formulating the conditions on which true belief constitutes knowledge. For decades, much of this epistemological undertaking has been dominated by a single strategy, referred to here as the modal approach. Shared by many of the most widely influential constraints on knowledge, including the sensitivity, safety, and anti-luck/risk conditions, this approach rests on a key underlying assumption — the (...) modal profiles available to known and unknown beliefs are in some way asymmetrical. The first aim of this paper is to deconstruct this assumption, identifying its plausibility with the way in which epistemologists frequently conceptualize human perceptual systems as excluding certain varieties of close error under conditions conducive to knowledge acquisition. The second aim of this paper is to then argue that a neural phase phenomenon indicates that this conceptualization is quite likely mistaken. This argument builds on the previous introduction of this neural phase to the context of epistemology, expanding the use of neural phase cases beyond relatively narrow questions about epistemic luck to a much more expansive critique of the modal approach as a whole.

Part of a symposium on Christopher Hill's book, Perceptual experience. Hill argues that perceptual experiences typically represent objects as having exotic properties that he calls Thouless properties. This and his representational pluralism allow him to attribute less perceptual error than the view that experiences represent simple relational properties (only). However, I think it is plausible that perceptual systems do make these sorts of errors, which although pervasive and systematic, are relatively subtle and perfectly explicable. I (...) also express some concerns about representational pluralism, especially in the context of a representationalist view of the phenomenal character of experience. (shrink)

The current investigation was conducted to elucidate whether errors of commission in the Sustained Attention to Response Task are indicators of perceptual or motor decoupling. Twenty-eight participants completed SARTs with motor and perceptual aspects of the task manipulated. The participants completed four different SART blocks whereby stimuli location uncertainty and stimuli acquisition were manipulated. In previous studies of more traditional sustained attention tasks stimuli location uncertainty reduces sustained attention performance. In the case of the SART the motor manipulation (...) , but not the perceptual manipulation significantly reduced commission errors. The results suggest that the majority of SART commission errors are likely to be indicators of motor decoupling not necessarily perceptual decoupling. (shrink)

Despite decades of study, mimicry continues to inspire and challenge evolutionary biologists. This essay aims to assess recent conceptual frameworks for the study of mimicry and to examine the links between mimicry and related phenomena. Mimicry is defined here as similarity in appearance and/or behavior between a mimic and a model that provides a selective advantage to the mimic because it affects the behavior of a receiver causing it to misidentify the mimic, and that evolved (or is maintained by selection) (...) because of those effects. Mimics copy cues or signals that are already in use as part of a stable communication system, but offer misleading information to receivers. Mimicry overlaps, both conceptually and evolutionarily, with camouflage and perceptual exploitation but the overlap is only partial, which may create some confusion. Certain types of camouflage (e.g. masquerade) conform to the definition of mimicry, while others (e.g. background matching) are not considered mimicry because they prevent detection rather than recognition of the camouflaged animal. Mimicry, on the other hand, works by exploiting peculiarities of the receiver at higher stages of sensory processing involving recognition and classification of stimuli. Perceptual exploitation models of trait evolution are also closely related to mimicry, and sensory traps in particular may act as a precursor for true mimicry to evolve. The common thread through these diverse phenomena is deception of a receiver by a mimic. Thus receiver deception (i.e. perceptual error) emerges as a key characteristic of mimicry shared with some types of camouflage and perceptual exploitation. (shrink)

Predictive Processing theory, hotly debated in neuroscience, psychology and philosophy, promises to explain a number of perceptual and cognitive phenomena in a simple and elegant manner. In some of its versions, the theory is ambitiously advertised as a new theory of conscious perception. The task of this paper is to assess whether this claim is realistic. We will be arguing that the Predictive Processing theory cannot explain the transition from unconscious to conscious perception in its proprietary terms. The explanations (...) offer by PP theorists mostly concern the preconditions of conscious perception, leaving the genuine material substrate of consciousness untouched. (shrink)

Formal models of appearance and reality have proved fruitful for investigating structural properties of perceptual knowledge. This paper applies the same approach to epistemic justification. Our central goal is to give a simple account of The Preface, in which justified belief fails to agglomerate. Following recent work by a number of authors, we understand knowledge in terms of normality. An agent knows p iff p is true throughout all relevant normal worlds. To model The Preface, we appeal to the (...) normality of error. Sometimes, it is more normal for reality and appearance to diverge than to match. We show that this simple idea has dramatic consequences for the theory of knowledge and justification. Among other things, we argue that a proper treatment of The Preface requires a departure from the internalist idea that epistemic justification supervenes on the appearances and the widespread idea that one knows most when free from error.

I here investigate whether there is any version of the principle of charity both strong enough to conflict with an error-theoretic version of nominalism (EN) about abstract objects, and supported by the considerations adduced in favour of interpretive charity in the literature. I argue that in order to be strong enough, the principle, which I call (Charity), would have to read, “For all expressions e, an acceptable interpretation must make true a sufficiently high ratio of accepted sentences containing e”. (...) I next consider arguments based on Davidson's intuitive cases for interpretive charity, the reliability of perceptual beliefs, and the reliability of “non-abstractive inference modes”, and conclude that none support (Charity). I then propose a diagnosis of the view that there must be some universal principle of charity ruling out (EN). Finally, I present a reason to think (Charity) is false, namely, that it seems to exclude the possibility of such disagreements as that between nominalists and realists. (shrink)

In chapter 5 of Knowledge and its Limits, T. Williamson formulates an argument against the principle (KK) of epistemic transparency, or luminosity of knowledge, namely “that if one knows something, then one knows that one knows it”. Williamson’s argument proceeds by reductio: from the description of a situation of approximate knowledge, he shows that a contradiction can be derived on the basis of principle (KK) and additional epistemic principles that he claims are better grounded. One of them is a reflective (...) form of the margin for error principle defended by Williamson in his account of knowledge. We argue that Williamson’s reductio rests on the inappropriate identification of distinct forms of knowledge. More specifically, an important distinction between perceptual knowledge and non-perceptual knowledge is wanting in his statement and analysis of the puzzle. We present an alternative account of this puzzle, based on a modular conception of knowledge: the (KK) principle and the margin for error principle can coexist, provided their domain of application is referred to the right sort of knowledge.

Predictive processing is often presented as a unifying framework for perception, action, and cognition, being able to explain most mental phenomena : with regard to perception, the brain harbours a generative model issuing top-down expectations that are matched against bottom-up sensory feedback. Mismatches lead to error messages and model updates until the brain is 'getting it right'. The core notion of prediction error minimization commits the framework to a specification of accuracy conditions. We therefore turn to issues related (...) to the determination of satisfaction conditions discussed in the philosophy of perception. In particular, we rely on work by Recanati who shows that the accuracy conditions of perceptual content are partly determined by the intentional mode and the perceiver. It is important to notice that the self can enter the specification of accuracy conditions in two ways, namely as subject or as object. Even if we do not perceive ourselves explicitly as an object, we always implicitly represent ourselves as subject. We discuss whether and how these two ways of self-representation can be respected in the predictive processing framework. (shrink)

Robert Brandom makes several mistakes in his discussion of Sellars's "Two-Ply" account of observation. Brandom does not recognize the difference in "level" between observation reports concerning physical objects and 'looks'-statements. He also denies that 'looks'-statements are reports or even make claims. They then demonstrate a more correct reading of Sellars on 'looks'-statements.

The aim of this paper is to defend the view that judgments based on episodic memory are immune to error through misidentification. I will put forward a proposal about the contents of episodic memories according to which a memory represents a perception of a past event. I will also offer a proposal about the contents of perceptual experiences according to which a perceptual experience represents some relations that its subject bears to events in the external world. The (...) combination of the two views will yield the outcome that the subject is always an intentional object of her own memories: In episodic memory, one remembers being the subject whose extrinsic properties were experienced in some past perception. For that reason, one cannot misidentify oneself in memory unless one is having an inaccurate memory. Thus, the source of immunity to error through misidentification in memory lies in the nature of mnemonic content. (shrink)

This paper concerns the role of the structural properties of representations in determining the nature of their content. I take as a starting point Fodor's (2007) and Heck's (2007) recent arguments making the iconic structure of perceptual representations essential in establishing their content as content of a different (nonconceptual) kind. I argue that the prima facie state–content error this strategy seems to display is nothing but a case of “state–content error error,” i.e., the mistake of considering (...) that the properties that characterize the type of content certain representations have are indeed independent of their structural properties. I also consider another objection to the general strategy, namely that it falls short of showing that the nonconceptual content of perceptual experiences thus established is the kind of content that figures in true explanations of intentional behavior. I concede this point in respect of Fodor's version of the strategy, while denying that it has any bearing on Heck's approach. The success of this objection in Heck's case ultimately depends, I argue, upon an unjustified commitment to a certain empirically suspect model of perception. (shrink)

In this paper I want to examine a claim made about the kind of immunity through misidentification relative to the first person (IEM) that attaches to action self-ascriptions. In particular, I want to consider whether we have reason to think a stronger kind of immunity attaches to action self-ascriptions, than attaches to self-ascriptions of bodily movement. I assume we have an awareness of our actions – agent’s awareness – and that agent’s awareness is not a form of perceptual bodily (...) awareness. The issue here is whether agents’ awareness grounds a kind of immunity to error that bodily awareness does not. However, perhaps more importantly, I want to argue that we only get a secure difference in immunity claims if have already decided whether a source of information is essentially first personal or not and made certain, not obviously warranted assumptions, about the transparency of content and about knowledge. If we hold that a subject’s knowledge of her actions is essentially first personal, in a way that a subject’s knowledge of her body through bodily awareness may not be, then we are better off arguing for that claim directly. Or so I will suggest. (shrink)

I address Peter Mott's 'Margins for Error and the Sorites Paradox' , pp. 494–503). Mott criticizes my account of inexact knowledge, on which it satisfies margin for error principles of the form 'If one knows in a given case, one avoids false belief in sufficiently similar cases'. Mott's arguments are shown to be fallacious because they ignore the fact that our knowledge of inexact knowledge is itself inexact. In the examples discussed, the first-level inexact knowledge is perceptual. (...) Since my defense of an epistemicist theory of vagueness explains our ignorance of truth-values in borderline cases as the result of knowledge the inexactness of which has a conceptual source, the paper also contributes to the defense of epistemicism about vagueness.

In this contribution, we address the issues concerning the semantic value of Wittgenstein’s subject “I”, as in “I have a toothache”, resulting from the use of predicates that involve first-person knowledge of the mental states to which they refer. As is well-known, these contexts give rise to the phenomenon of ‘immunity to error through misidentification’ : the utterer of cannot be mistaken as to whether he is the person having a toothache. We provide a series of arguments in favor (...) of a principled distinction between a de facto IEM, grounded in perceptual and proprioceptive judgments, and a de iure IEM, grounded in experience reports whereby the experience wears the experiencer on its sleeve. From this perspective, the no-referent account of subject “I” advocated by Wittgenstein/Anscombe is correct. In fact, we show how this analysis can be made compatible with a Kaplanian account of first-person indexicals, by identifying the speaker in the context of utterance with the person who has access to the reported private experience.

In recent years sense–datum theories have received much criticism, but there is one type of error frequently involved in the sense–datum concept which is in need of further consideration. This error consists in a category confusion of such a nature that what is properly regarded as perceptual mode is treated as though it were the attribute of a thing. The mode or manner of perception is mistakenly transferred to the sense–datum with results which a little careful reflection (...) shows to be absurd. In what follows a specific case of this error connected with the notion of phenomenal organization will be discussed. (shrink)

In this paper we shall address some issues concerning the relation between the content and the nature of perceptual experience. More precisely, we shall ask whether the claim that perceptual experiences are by nature relational implies that they cannot be intentional. As we shall see, much depends in this respect on the way one understands the possibility for one to be wrong about the phenomenal nature of one’s own experience. We shall argue that once this very possibility is (...) properly understood, the metaphysical claim that perceptual experiences are relational is compatible with the view that they are intentional. Before presenting the argument, we should try to articulate some elements of an intentionalist approach concerning the role of experience in our relation to ourselves and to our environment. The picture should offer a motivation for the arguments that follow. more about illusions etc (see Clatilde’s comments). (shrink)

Contemporary scholars have begun to document the extensive influence of the sixth to seventh century Buddhist philosopher Dharmakīrti on Pratyabhijñā Śaiva thought. Utpaladeva and Abhinavagupta’s adaptation of Dharmakīrti’s apoha theory provides a striking instance of the creative ways in which these Śaivas use Dharmakīrti’s ideas to argue for positions that Dharmakīrti would emphatically reject. Both Dharmakīrti and these Śaivas emphasize that the formation of a concept involves both objective and subjective factors. Working within a certain perceptual environment, factors such (...) as a subject’s desires, habits, and conditioning lead him or her to form a concept based on excluding what is not relevant to the accomplishment of his or her goal. However, the two differ in their account of the relationship between concepts and subject/object duality itself. While Dharmakīrti claims that the division of a cognition into subject, object, and awareness is nonconceptual, the subtly shifted definition of a concept that these Śaivas employ allows them to claim that the error of subject/object duality is actually conceptual. This seemingly small difference in their respective evaluations of the nature of subject/object error has surprisingly large consequences. If, as these Śaivas claim, any awareness involving a duality is conceptual, then subject and object are concepts. Moreover, if the formation of a concept requires desire, then some kind of desire must be inherent to consciousness itself before the formation of a limited subject/object pair. In short, ultimate consciousness must be Śiva, who possesses the freedom to will any and all possible realities. (shrink)

Color relationalism is the view that colors are constituted in terms of relations to perceiving subjects. Among its explanatory virtues, relation- alism provides a satisfying treatment of cases of perceptual variation. But it can seem that relationalists lack resources for saying that a representa- tion of x’s color is erroneous. Surely, though, a theory of color that makes errors of color perception impossible cannot be correct. In this paper I’ll argue that, initial appearances notwithstanding, relationalism contains the resources to (...) account for errors of color perception. I’ll conclude that worries about making room for error are worries the relationalist can meet. (shrink)
