As standardly conceived, an illusion is an experience of an object o appearing F where o is not in fact F. Paradigm examples of color illusion, however, do not fit this pattern. A diagnosis of this uncovers different sense of appearance talk that is the basis of a dilemma for the standard conception. The dilemma is only a challenge. But if the challenge cannot be met, then any conception of experience, such as representationalism, that is committed to the (...) standard conception is false. Perhaps surprisingly, naïve realism provides a better account of color illusion.An apparence ymaad by som Magyk. Chaucer. (shrink)
Saul Smilansky presents an original new approach to the problem of free will, which lies at the heart of morality and self-understanding. He maintains that the key to the problem is the role played by illusion. Smilansky boldly claims that we could not live adequately with a complete awareness of the truth about human freedom and that illusion lies at the center of the human condition.
Sir Peter Strawson’s ‘Freedom and Resentment’ was a landmark in the philosophical understanding of the free will problem. Building upon it, I attempt to defend a novel position, which purports to provide, in outline, the next step forward. The position presented is based on the descriptively central and normatively crucial role of illusion in the issue of free will. Illusion, I claim, is the vital but neglected key to the free will problem. The proposed position, which may be (...) called ‘Illusionism’, is shown to follow both from the strengths and from the weaknesses of Strawson’s position. (shrink)
In recent years, a pair of intriguing phenomena has caused researchers working on vision and visual attention to reevaluate many of their assumptions. These phenomena, which have come to be called change blindness (CB) and inattentional blindness (IB), have led many to the conclusion that ordinary perceivers labor under a ``grand illusion'' concerning perception - an illusion that is..
In The illusion of conscious will , Daniel Wegner offers an exciting, informative, and potentially threatening treatise on the psychology of action. I offer several interpretations of the thesis that conscious will is an illusion. The one Wegner seems to suggest is "modular epiphenomenalism": conscious experience of will is produced by a brain system distinct from the system that produces action; it interprets our behavior but does not, as it seems to us, cause it. I argue that the (...) evidence Wegner presents to support this theory, though fascinating, is inconclusive and, in any case, he has not shown that conscious will does not play a crucial causal role in planning, forming intentions, etc. This theory's potential blow to our self-conception turns out to be a glancing one.

Autism spectrum disorder (ASD) is characterised by differences in unimodal and multimodal sensory and proprioceptive processing, with complex biases towards local over global processing. Many of these elements are implicated in versions of the rubber hand illusion (RHI), which were therefore studied in high-functioning individuals with ASD and a typically developing control group. Both groups experienced the illusion. A number of differences were found, related to proprioception and sensorimotor processes. The ASD group showed reduced sensitivity to visuotactile-proprioceptive discrepancy (...) but more accurate proprioception. This group also differed on acceleration in subsequent reach trials. Results are discussed in terms of weak top-down integration and precision-accuracy trade-offs. The RHI appears to be a useful tool for investigating multisensory processing in ASD. (shrink)
This major study of Kant provides a detailed examination of the development and function of the doctrine of transcendental illusion in his theoretical philosophy. The author shows that a theory of 'illusion' plays a central role in Kant's arguments about metaphysical speculation and scientific theory. Indeed, she argues that we cannot understand Kant unless we take seriously his claim that the mind inevitably acts in accordance with ideas and principles that are 'illusory'. Taking this claim seriously, we can (...) make much better sense of Kant's arguments and reach a deeper understanding of the role he allots human reason in science. (shrink)
The belief that conscious will is merely "an illusion created by the brain" appears to be gaining in popularity among cognitive neuroscientists. Its main adherents usually refer to the classic, but controversial 'Libet-experiments', as the empirical evidence that vindicates this illusion-claim. However, based on recent work that provides other interpretations of the Libet-experiments, we argue that the illusion-claim is not only empirically invalid, but also theoretically incoherent, as it is rooted in a category mistake; namely, the presupposition (...) that neuronal activity causes conscious will. We show that the illusion-claim is based on the behaviorist 'input-output' paradigm, and discuss the notions of 'self-organization' and 'self-steering' to provide an alternative perspective on the causal efficacy of conscious will. In the final sections, a tentative theoretical picture is sketched of conscious will as an instance of self-steered self-organization. We conclude that the subjective experience of conscious will is not a misguided one, but rather that the mechanisms supporting conscious will are considerably more complex than mainstream cognitive neuroscience currently acknowledges.

In this paper we introduce a paradigm of experiment which, we believe, is of interest both in psychology and philosophy. There the subject wears an HMD (head-mount display), and a camera is set up at the upper corner of the room, in which the subject is. As a result, the subject observes his own body through the HMD. We will mainly focus on the philosophical relevance of this experiment, especially to the thesis of so-called 'immunity to error through misidentification relative (...) to the first-person pronoun'. We will argue that one experiment conducted in this setting, which we call the bodily illusion experiment, provides a counterexample to that thesis. (shrink)
The psychological concept of illusion is defined as a process involving an interaction of logical and empirical considerations. Common usage suggests that an illusion is a discrepancy between one's awareness and some stimulus. Following preliminary definitions of classes of stimuli, five definitions of illusion are considered, based upon the possible discrepancies between awareness and a stimulus. It is found that each of these definitions fails to make important distinctions, even to the point of equating all illusory and (...) perceptual phenomena. This dilemma is resolved by redefining illusion without reference to truth or falsity, but relative to the functioning of a given perceptual system under different conditions. The definition accepted as best is 'a discrepancy between one's perceptions of an object or event observed under different conditions'. Conditions may differ in terms of stimulus exposure, stimulus context, or experiental context. The philosophical and psychological implications are discussed of accepting a definition of illusion not based on a discrepancy between awareness and a stimulus. (shrink)
Why does cinema exert such power over our emotions? Many have wanted to answer by appeal to the idea that film sustains some illusion concerning the events it narrates. I compare three such views: that film sustains the illusion that those events are before us; that it sustains that illusion, but only partially; and that, though viewers are always fully aware of seeing pictures, those pictures are experienced as the moving photographic record of the narrated events. I (...) identify these positions’ successes and failures in explaining film’s emotional power, and various ways in which the issue between them might be tested further. (shrink)
The Appendix to the Transcendental Dialectic of Kant's first Critique is notorious for two reasons. First, it appears to contradict itself in saying that the idea of the systematic unity of nature is and is not transcendental. Second, in the passages in which Kant appears to espouse the former alternative, he appears to be making a significant amendment to his account of the conditions of the possibility of experience in the Transcendental Analytic. I propose a solution to both of these (...) difficulties. With regard to the first, I argue that Kant does not contradict himself. With regard to the second, I argue that Kant is not making any change to his view of the conditions of the possibility of experience espoused in the Transcendental Analytic. The underlying cause of these apparent problems is also their solution: the transcendental illusion that nature is necessarily systematic. (shrink)
In rubber hand illusions and full body illusions, touch sensations are projected to non-body objects such as rubber hands, dolls or virtual bodies. The robustness, limits and further perceptual consequences of such illusions are not yet fully explored or understood. A number of experiments are reported that test the limits of a variant of the rubber hand illusion. Methodology/Principal Findings -/- A variant of the rubber hand illusion is explored, in which the real and foreign hands are aligned (...) in personal space. The presence of the illusion is ascertained with participants' scores and temperature changes of the real arm. This generates a basic illusion of touch projected to a foreign arm. Participants are presented with further, unusual visuotactile stimuli subsequent to onset of the basic illusion. Such further visuotactile stimulation is found to generate very unusual experiences of supernatural touch and touch on a non-hand object. The finding of touch on a non-hand object conflicts with prior findings, and to resolve this conflict a further hypothesis is successfully tested: that without prior onset of the basic illusion this unusual experience does not occur. Conclusions/Significance -/- A rubber hand illusion is found that can arise when the real and the foreign arm are aligned in personal space. This illusion persists through periods of no tactile stimulation and is strong enough to allow very unusual experiences of touch felt on a cardboard box and experiences of touch produced at a distance, as if by supernatural causation. These findings suggest that one's visual body image is explained away during experience of the illusion and they may be of further importance to understanding the role of experience in delusion formation. The findings of touch on non-hand objects may help reconcile conflicting results in this area of research. In addition, new evidence is provided that relates to the recently discovered psychologically induced temperature changes that occur during the illusion. (shrink)
Tibetan Buddhist writings frequently state that many of the things we perceive in the world are in fact illusory, as illusory as echoes or mirages. In Twelve Examples of Illusion , Jan Westerhoff offers an engaging look at a dozen illusions--including magic tricks, dreams, rainbows, and reflections in a mirror--showing how these phenomena can give us insight into reality. For instance, he offers a fascinating discussion of optical illusions, such as the wheel of fire (the "wheel" seen when a (...) torch is swung rapidly in a circle), discussing Tibetan explanations of this phenomenon as well as the findings of modern psychology, and significantly clarifying the idea that most phenomena--from chairs to trees--are similar illusions. The book uses a variety of crystal-clear examples drawn from a wide variety of fields, including contemporary philosophy and cognitive science, as well as the history of science, optics, artificial intelligence, geometry, economics, and literary theory. Throughout, Westerhoff makes both Buddhist philosophical ideas and the latest theories of mind and brain come alive for the general reader. -/- "This delightful book offers a rich and satisfying philosophical feast to anyone interested in the phenomenon of illusion itself or in the Buddhist analysis of the human condition. Westerhoff draws together classical Buddhist scholarship, contemporary cognitive science and his own judicious philosophical reflection in a serious but refreshingly accessible engagement with the Buddhist tradition in the exploration of the role of illusion in our cognitive and emotional lives." Jay L. Garfield, author of Fundamental Wisdom of the Middle Way: Nagarjuna's Mulamadhyamakakarika -/- "Jan Westerhoff creatively juxtaposes an important Buddhist study of illusion with fascinating modern researches on illusory experiences, using the latter to illuminate the former. The result is a revealing account of the pervasiveness of illusion in our cognitive experience and the very structure of our cognitive apparatus. It brings to life the Buddhist discussion of illusion, making it relevant to our everyday experience instead of being high-minded intellectual exercises only." -/- Tao Jiang, author of Contexts and Dialogue: Yogacara Buddhism and Modern Psychology on the Subliminal Mind -/- "The twelve similes for the illusory nature of this world are very profound, and Westerhoff does them wonderful justice in this excellent book." -/- Robert Thurman, Jey Tsong Khapa Professor of Buddhist Studies, Columbia University.

In the following essay, I attempt to defend a novel position on ‘the free will problem’. In particular, I intend to provide (in outline) a position based on the descriptively central and normatively crucial role of illusion in the free will issue. Illusion, I claim, is the vital but neglected key to the free will problem. The proposed position, which can be called ‘Illusionism’, can be defended independently from its derivation from P. F. Strawson’s ‘reactive-naturalism’. However, since the (...) role of illusion emerges only at a late stage of the train of arguments pertaining to free will, we will get to our destination by ‘free-riding’ most of the way on Strawson’s train, and then continue a bit further by ourselves, into the uncharted and dangerous Land Of Illusion.

Recent debates between representational and relational theories of perceptual experience sometimes fail to clarify in what respect the two views differ. In this essay, I explain that the relational view rejects two related claims endorsed by most representationalists: the claim that perceptual experiences can be erroneous, and the claim that having the same representational content is what explains the indiscriminability of veridical perceptions and phenomenally matching illusions or hallucinations. I then show how the relational view can claim that errors associated (...) with perception should be explained in terms of false judgments, and develop a theory of illusions based on the idea that appearances are properties of objects in the surrounding environment. I provide an account of why appearances are sometimes misleading, and conclude by showing how the availability of this view undermines one of the most common ways of motivating representationalist theories of perception.

Philosophers of mind have recently sought to establish a theoret- ical use for nonconceptual content. Although there is disagreement about what nonconceptual content is supposed to be, this much is clear. A state with nonconceptual content is mental. Hence, while one may deny that refrigerators and messy rooms have conceptual capacities, their states, as physical and not mental, do not have nonconceptual content. A state with nonconceptual content is also intentional, which is to say that it represents a feature of (...) the world for a subject. It may be tempting to think of qualitative states as having nonconceptual content since they can be experienced by indi- viduals independently of their possession of the requisite concepts, e.g. someone could experience pains, itches or tingles without possessing the concept pain, itch or tingle. But on such a view, one would have to assume that qualitative states are representational since mental states cannot be candidates for nonconceptuality unless they have intentional properties.2.

There is a widespread, popular view—and one I basically endorse—that Nietzsche is, in one sense of the word, a nihilist. As Arthur Danto put it some time ago, according to Nietzsche, “there is nothing in [the world] which might sensibly be supposed to have value.” As interpreters of Nietzsche, though, we cannot simply stop here. Nietzsche's higher men, Übermenschen, “genuine philosophers”, free spirits—the types Nietzsche wants to bring forth from the human, all-too-human herds he sees around him with the fish (...) hooks, as he says, of his books—seem to engage in what looks like valuing. These free spirits are supposed to revalue the old values—revaluing, as is clear from the texts, is not simply to remove the old values from circulation (Nietzsche uses “umwerten” and not “entwerten”)—and they are supposed to create new values. And, of course, Nietzsche himself, free spirit that he is, takes on the task of revaluing all values and seems to assert many a strident evaluation. So we need to say more here. What are Nietzsche and his free spirits up to when they engage in what looks, for all the world, like a practice of valuing? What is the practice of valuing Nietzsche is recommending for his free spirits? I argue for two claims: (i) First, we end up facing an interpretive puzzle when we attempt to explain how Nietzsche's free spirits are supposed to engage in a practice of valuing. (ii) Second, we can solve the interpretive puzzle by taking Nietzsche's free spirits to be engaged in a fictionalist simulacrum of valuing. (shrink)
Wegner’s analysis of the illusion of conscious will is close to my own account of how conscious experiences relate to brain processes. But our analyses differ somewhat on how conscious will is not an illusion. Wegner argues that once conscious will arises it enters causally into subsequent mental processing. I argue that while his causal story is accurate, it remains a first-person story. Conscious free will is not an illusion in the sense that this first-person story is (...) compatible with and complementary to a third-person account of voluntary processing in the mind/brain.

The question how to account for illusion has had a prominent role in shaping theories of perception throughout the history of philosophy. Prevailing philosophical wisdom today has it that phenomena of illusion force us to choose between the following two options. First, reject altogether the early modern empiricist idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience. Instead we must characterize perceptual experience entirely in terms (...) of its representational content. Second, retain the early modern idea that the core subjective character of experience is simply constituted by the identity of its direct objects, but admit that these must be mind-dependent entities, distinct from the mind-independent physical objects we all know and love. I argue here that the early modern empiricists had an indispensable insight. The idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience is more fundamental than any appeal to perceptual content, and can account for illusion, and indeed hallucination, without resorting to the problematic postulation of any such mind-dependent objects.

de Anima III.10 characterizes akrasia as a conflict between phantasia (“imagination”) on one side and rational cognition on the other: the akratic agent is torn between an appetite for what appears good to her phantasia and a rational desire for what her intellect believes good. This entails that akrasia is parallel to certain cases of perceptual illusion. Drawing on Aristotle's discussion of such cases in the de Anima and de Insomniis , I use this parallel to illuminate the difficult (...) discussion of akrasia in Nicomachean Ethics VII.3, arguing that its account of akrasia as involving ignorance is compatible with, and in fact crucially supplements, the more straightforward account we find elsewhere in the corpus of akrasia as a struggle between desires.

Mark Changizi et al. (2008) claim that it is possible systematically to organize more than 50 kinds of illusions in a 7 × 4 matrix of 28 classes. This systematization, they further maintain, can be explained by the operation of a single visual processing latency correction mechanism that they call “perceiving the present” (PTP). This brief report raises some concerns about the way a number of illusions are classified by the proposed systematization. It also poses two general problems—one empirical and (...) one conceptual—for the PTP approach. (shrink)
In recent decades, with advances in the behavioral, cognitive, and neurosciences, the idea that patterns of human behavior may ultimately be due to factors beyond our conscious control has increasingly gained traction and renewed interest in the age-old problem of free will. In this book I examine both the traditional philosophical problems long associated with the question of free will, such as the relationship between determinism and free will, as well as recent experimental and theoretical work directly related to consciousness (...) and human agency. I argue that our best scientific theories indeed have the consequence that factors beyond our control produce all of the actions we perform and that because of this we do not possess the kind of free will required for genuine or ultimate responsibility. I further argue that the strong and pervasive belief in free will, which I consider an illusion, can be accounted for through a careful analysis of our phenomenology and a proper theoretical understanding of consciousness. Indeed, the primary goal of this book is to argue that our subjective feeling of freedom, as reflected in the first-person phenomenology of agentive experience, is an illusion created by certain aspects of our consciousness. So after working to establish that free will is an illusion in the early chapters, I then proceed to give a novel account of just how that illusion is created in the later chapters. I present my illusionist account using one leading theory of consciousness—the higher-order thought (or HOT) theory of consciousness. I maintain that by combining the theoretical framework of the HOT theory with empirical findings in the behavioral, cognitive, and neurosciences, we can come to see that the illusion of free will is created by the particular way our higher-order thoughts make us conscious of our mental states and how our sense of self is constructed within consciousness.

Wegner (Wegner, D. (2002). The illusion of conscious will. MIT Press) argues that conscious will is an illusion, citing a wide range of empirical evidence. I shall begin by surveying some of his arguments. Many are unsuccessful. But one—an argument from the ubiquity of self-interpretation—is more promising. Yet is suffers from an obvious lacuna, offered by so-called ‘dual process’ theories of reasoning and decision making (Evans, J., & Over, D. (1996). Rationality and reasoning. Psychology Press; Stanovich, K. (1999). (...) Who is rational? Studies of individual differences in reasoning. Lawrence Erlbaum; Frankish, K. (2004). Mind and supermind. Cambridge University Press). I shall argue that this lacuna can be filled by a plausible a priori claim about the causal role of anything deserving to be called ‘a will.’ The result is that there is no such thing as conscious willing: conscious will is, indeed, an illusion.

It is common among philosophers who take an interest in the phenomenon of vagueness in natural language not merely to acknowledge higher-order vagueness but to take its existence as a basic datum— so that views that lack the resources to account for it, or that put obstacles in the way, are regarded as deficient just on that score. My main purpose in what follows is to loosen the hold of this deeply misconceived idea. Higher-order vagueness is no basic datum but (...) an illusion, fostered by misunderstandings of the nature of (ordinary, if you will ‘first-order’) vagueness itself. To see through the illusion is to take a step that is prerequisite for a correct understanding of vagueness, and for any satisfying dissolution of its attendant paradoxes. (shrink)
Plato links pleasure with illusion, and this link explains his rejection of the view that all desires are rational desires for the good. The Protagoras and Gorgias show connections between pleasure and illusion: the Republic develops these into a psychological theory. One part of the soul is not only prone to illusions, but also incapable of the kind of reasoning that can dispel them. Pleasure appears good; therefore this part of the soul (the appetitive part) desires pleasures qua (...) good but ignores reasoning about what is really good. Hence the new moral psychology of the Republic: not all desires are rational, and thus virtue depends on bringing one's non-rational desires under the control of reason. (shrink)
The thesis that there is a troublesome explanatory gap between the phenomenal aspects of experiences and the underlying physical and functional states is given a number of different interpretations. It is shown that, on each of these interpretations, the thesis is false. In supposing otherwise, philosophers have fallen prey to a cognitive illusion, induced largely by a failure to recognize the special character of phenomenal concepts.
The purpose of this paper is to defend what I call the action-oriented coding theory (ACT) of spatially contentful visual experience. Integral to ACT is the view that conscious visual experience and visually guided action make use of a common subject-relative or 'egocentric' frame of reference. Proponents of the influential two visual systems hypothesis (TVSH), however, have maintained on empirical grounds that this view is false (Milner & Goodale, 1995/2006; Clark, 1999; 2001; Campbell, 2002; Jacob & Jeannerod, 2003; Goodale & (...) Milner, 2004). One main source of evidence for TVSH comes from behavioral studies of the comparative effects of size-contrast illusions on visual awareness and visuo- motor action. This paper shows that not only is the evidence from illusion studies inconclusive, there is a better, ACT-friendly interpretation of the evidence that avoids serious theoretical difficulties faced by TVSH.

The focus of this paper is on E. H. Gombrich's claim that pictorial perception is a case of illusion. My aim is to point out that, on the one hand, the interpretation of this claim that is widely accepted in pictorial theory is not supported by Gombrich's analysis of pictorial perception; and, on the other hand, that the interpretation of the claim that I see as more compatible with Gombrich's analysis is not consistent with relevant facts about our relation (...) to pictures. However, I will argue, Gombrich's elaboration of the claim of illusion is significant to the extent that it highlights important aspects of the system of pictorial representation. (shrink)
Following the pattern set by the early German Romantics, Kierkegaard conveys many of his insights through literature rather than academic prose. What makes him a valuable member of this tradition is the theory he develops to support it, his so-called “theory of indirect communication.” The most exciting aspect of this theory concerns the alleged importance of indirect communication: Kierkegaard claims that there are some projects only it can accomplish. This paper provides a critical account of two arguments Kierkegaard offers in (...) defense of this claim. The first argument is that he needs to use indirect communication in order to discourage people from losing themselves in the “crowd”. The second argument is that he needs to use it in order to help people out of a “monstrous illusion”. It is shown that while both arguments justify Kierkegaard’s decision to use indirect communication, neither one supports the original claim about its indispensability. (shrink)
Experiments on scene perception and change blindness suggest that the visual system does not construct detailed internal models of a scene. These experiments therefore call into doubt the traditional view that vision is a process in which detailed representations of the environment must be constructed. The non-existence of such detailed representations, however, does not entail that we do not perceive the detailed environment. The “grand illusion hypothesis” that our visual world is an illusion rests on (1) a problematic (...) “reconstructionist” conception of vision, and (2) a misconception about the character of perceptual experience.

This paper considers a form of scepticism according to which sentences, along with other linguistic entities such as verbs and phonemes, etc., are never realized. If, whenever a conversational participant produces some noise or other, they and all other participants assume that a specific sentence has been realized (or, more colloquially, spoken), communication will be fluent whether or not the shared assumption is correct. That communication takes place is therefore, one might think, no ground for assuming that sentences are realized (...) during a typical conversation. I reject both this ‘folie-a-deux’ view and the arguments for it due to Georges Rey. I do so by drawing on Gilbert Harrnan’s no-false-lemmas principle. Since testimony is a form of knowledge and, according to the principle, knowledge cannot depend essentially on false assumptions, testimony is incompatible with the claim that sentence realization is but an illusion. Much of the paper is given over to defending this appeal to the no-false-lemmas principle. After all, a more attractive option might seem to be to infer instead that the principle is itself falsified by the folie-a-deux view. (shrink)
Gregory Currie, arguing against recent psychoanalytic and semiotic film theory, has defended various realist theses about film. The strongest of these is that ‘weak illusionism’—the view that the motion of film images is an illusion—is false. That is, Currie believes film images really do move. In this paper I defend the common-sense position of weak illusionism, firstly by showing that Currie underestimates the power of some arguments for it, especially one based on the mechanics of projection, and secondly by (...) showing that film images exhibit neither garden-variety motion, nor a special response-dependent kind.

We seem, or so it seems to some theorists, to experience a rich stream of highly detailed information concerning an extensive part of our current visual surroundings. But this appearance, it has been suggested, is in some way illusory. Our brains do not command richly detailed internal models of the current scene. Our seeings, it seems, are not all that they seem. This, then, is the Grand Illusion. We think we see much more than we actually do. In this (...) paper I shall (briefly) rehearse the empirical evidence for this rather startling claim, and then critically examine a variety of responses. One especially interesting response is a development of the so-called ‘skill theory’, according to which there is no illusion after all. Instead, so the theory goes, we establish the required visual contact with our world by an ongoing process of active exploration, in which the world acts as a kind of reliable, interrogable, external memory (Noe, Pessoa and Thompson (2000), Noe (2001). The most fully worked-out versions of this response ( Noe and O’Regan (2000), O’Regan and Noe 2001) tend, however, to tie the contents of conscious visual experience rather too tightly to quite low-level features of this ongoing sensorimotor engagement. This (I shall argue) undervalues the crucial links between perceptual experience, reason and intentional action, and opens the door to a problem that I will call ‘sensorimotor chauvinism’: the premature welding of experiential contents to very specific details of our embodiment and sensory apparatus. Drawing on the dual visual systems hypothesis of Milner and Goodale (1995), I sketch an alternative version of the skill theory, in which the relation between conscious visual experience and the low-level details of sensorimotor engagement is indirect and non-constitutive. The hope is thus to embrace the genuine insights of the skill theory response, while depicting conscious visual experience as most tightly geared to knowing and reasoning about our world.. (shrink)
This paper resurrects two discredited ideas in the philosophy of mind. The first: the idea that perceptual illusion might have something metaphysically significant to tell us about the nature of phenomenal consciousness. The second: that the colours and other qualities that ‘fill’ our sensory fields are occurrent properties (rather than representations of properties) that are, nevertheless, to be distinguished from the ‘objective’ properties of things in the external world. Theories of consciousness must recognize the existence of what Daniel Dennett (...) mockingly labels ‘figment,’ but this result—though metaphysically and epistemologically significant—is not incompatible with either physicalism or naturalized semantics.

Projecting Illusion offers a systematic analysis of the impression of reality in the cinema and the pleasure it gives to the film spectator. Film provides a compelling experience that can be considered as a form of illusion akin to the experience of day-dream and dream. Examining the concept of illusion and its relationship to fantasy in the experience of visual representation, Richard Allen situates his explanation within the context of an analytical criticism of contemporary film and critical (...) theory. He argues that many contemporary film theorists correctly identify the significance of the impression of reality, although their explanation of it is incorrect because of an invalid philosophical understanding of the relationship between the mind, representation and reality. Offering a clear presentation and critique of the central arguments of contemporary film and critical theory, Allen also touches on fundamental issues in current discourses of philosophy, art history and feminist theory.

Daniel Wegner argues that conscious will is an illusion. I examine the adequacy of his theory of apparent mental causation and whether, if accurate, it suggests that our experience of agency and authorship should be considered illusory. I examine various interpretations of this claim and raise problems for each interpretation. I also distinguish between the experiences of agency and authorship.
The Müller-Lyer illusion is the natural consequence of the construction of the vertebrate eye, retina and visual processing system. Due to imperfections in the vertebrate eye and retina and due to the subsequent processing in the system by ever increasing receptive fields, the visual information becomes less and less precise with respect to exact location and size. The consequence of this is that eventually the brain has to calculate a weighted mean value of the information, which is spread out (...) over a population of neurons. In the case of the Müller-Lyer illusion this inevitably leads to extension of one and reduction of the other line. The arguments presented explain several published experimental results concerning the Müller-Lyer illusion and shed new light upon the philosophical neutrality of observation sentences. (shrink)
Experimental phenomenology has demonstrated that perception is much richer than stimulus. As is seen in color perception, one and the same stimulus provides more than several modes of appearance or perceptual dimensions. Similarly, there are various perceptual dimensions in form perception. Even a simple geometrical figure inducing visual illusion gives not only perceptual impressions of size, shape, slant, depth, and orientation, but also affective or aesthetic impressions. The present study reviews our experimental phenomenological work on visual illusion and (...) experimental aesthetics, and examines how aesthetic preference is influenced by stimulus factors determining visual illusions including anomalous surface and transparency as well as geometrical illusion. Along with line figures producing geometrical illusions, illusory surface figures inducing neon color spreading and transparency effects were used as test patterns. Participants made both of psychophysical judgments and of aesthetic judgments for the same test pattern. Both of geometrical illusions and aesthetic preferences were found to change similarly as a function of stimulus variables such as the number of filling lines and the size ratio of the inner and outer figural components. Also, following specific stimulus variables such as lightness contrast ratio and spatial interval between inducing figural elements (so called ``packmen''), strong effects of color spreading and transparency were accompanied with strong preferences. It seems that the paradigm to investigate aesthetic phenomena along with perceptual dimensions is useful to bridge the gap between experimental phenomenology and experimental aesthetics. (shrink)

One especially interesting response is a development of the so-called ‘skill theory’, according to which there is no illusion after all. Instead, so the theory goes, we establish the required visual contact with our world by an ongoing process of active exploration, in which the world acts as a kind of reliable, interrogable, external memory (Noe, Pessoa and.

Wegner’s argument on the illusory nature of conscious will, as developed in The Illusion of Conscious Will ( 2002 ) and other publications, has had major impact. Based on empirical data, he develops a theory of apparent mental causation in order to explain the occurrence of the illusion of conscious will. Part of the evidence for his argument is derived from a specific interpretation of the phenomenon of auditory verbal hallucinations as they may occur in schizophrenia. The aim (...) of this paper is to evaluate the validity of the evidence on auditory verbal hallucinations as employed by Wegner. I conclude that auditory hallucinations do not provide solid evidence for Wegner’s theory. Moreover, the phenomena in schizophrenia provide, in fact, an argument against part of Wegner’s theory of apparent mental causation. (shrink)
Founding our analysis on the Geneva-Brussels approach to quantum mechanics, we use conventional macroscopic objects as guiding examples to clarify the content of two important results of the beginning of twentieth century: Einstein–Podolsky–Rosen’s reality criterion and Heisenberg’s uncertainty principle. We then use them in combination to show that our widespread belief in the existence of microscopic particles is only the result of a cognitive illusion, as microscopic particles are not particles, but are instead the ephemeral spatial and local manifestations (...) of non-spatial and non-local entities.

There is a popular view on depiction which holds that convincingly realistic paintings depict their subjects through evoking in the spectator the illusion of seeing these very subjects face to face. There is, as it were, an exact 'match' between the visual experience of seeing something in a picture and the corresponding visual experience one would entertain if one were to stand in front of the real thing. This view, which we shall call 'illusionism', supports the widespread assumption that (...) some kinds of pictures -- notably post-Renaissance perspective paintings -- provide the correct, 'natural' way to depict physical space because they capture the way the visual system enables one to see the world. The most notable defence of illusionism has been offered by Ernst Gombrich. In his Art and Illusion, Gombrich (1960) argues that the development of Western art consists in a series of discoveries about the nature of visual perception that eventually lead to pictorial techniques that are able to elicit illusionary visual experiences on part of the spectator and thus reach the perfection of naturalistic representation.

Wegner's monograph presents the view that conscious will is a feeling that we experience when we perform an action through a mechanistic process of the brain, rather than a mental force that causes the action. The view is supported by several lines of evidence in which conscious will is dissociated from the actual performance of voluntary movements, as in automatism. The book further extends an insightful analysis of the mental system behind the illusion of conscious will and inspires neuroscientists (...) to reflect on its neural substrates. (shrink)
Patrick Suppes'' set-theoretical approach to the analysis of theories, and Joseph D. Sneed''s metatheory are briefly outlined. The notions of observation, illusion and hallucination are reconstructed according to these approaches. It is argued that the terms perception and truth are theoretical with respect to observation but nontheoretical with respect to illusion and hallucination. Hallucination is construed as a special kind of illusion.
Ever since Berkeley discussed the problem at length in his Essay Toward a New Theory of Vision, theorists of vision have attempted to explain why the moon appears larger on the horizon than it does at the zenith. Prevailing opinion has it that the contemporary perceptual psychologists Kaufman and Rock have finally explained the illusion. This paper argues that Kaufman and Rock have not refuted a Berkeleyan account of the illusion, and have over-interpreted their own experimental results. The (...) moon illusion remains unexplained, and a Berkeleyan account is still a contender. (shrink)
Experiments on scene perception and change blindness suggest that the visual system does not construct detailed internal models of a scene. These experiments therefore call into doubt the traditional view that vision is a process in which detailed representations of the environment must be constructed. The non-existence of such detailed representations, however, does not entail that we do not perceive the detailed environment. The “grand illusion hypothesis” that our visual world is an illusion rests on (1) a problematic (...) “reconstructionist” conception of vision, and (2) a misconception about the character of perceptual experience.

In "The Illusion of Conscious Will," Daniel Wegner (2002) argues that our commonsense belief that our conscious choices cause our voluntary actions is mistaken. Wegner cites experimental results that suggest that brain processes initiate our actions before we become consciously aware of our choices, showing that we are systematically wrong in thinking that we consciously cause our actions. Wegner's view leads him to conclude, among other things, that moral responsibility does not exist. In this article I propose some ways (...) that traditional philosophical defenders of moral responsibility, both compatibilists and libertarians, might accept Wegner's empirical premise regarding the will but amend their theories so that they may reject his conclusion regarding moral responsibility.

Here, we assess the usefulness of first-person methods for the study of embodiment during the rubber hand illusion (RHI). Participants observed a rubber hand being stroked synchronously and asynchronously with their concealed hand after which they made proprioceptive judgments about the location of their hand and completed a self-report questionnaire. A randomly selected cohort was further interviewed during the illusion and their transcripts analyzed using interpretative phenomenological analysis (IPA). Results showed that the IPA group experienced a more intense (...) embodied experience during the RHI, measured by proprioceptive distortion and self-report. IPA revealed four main themes of embodied experience: recalibration of the body schema ; violation of the body schema ; multisensory integration ; and illusory experience over time . The report of agency was a significant predictor of proprioceptive distortion. This study shows how first-person methodologies can be empirically rigorous and how the introspective interview provides a rich, detailed account of embodied experience. (shrink)
In this paper I argue that any adequate evolutionary ethical theory needs to account for moral belief as well as for dispositions to behave altruistically. It also needs to be clear whether it is offering us an account of the motivating reasons behind human behaviour or whether it is giving justifying reasons for a particular set of behaviours or, if both, to distinguish them clearly. I also argue that, unless there are some objective moral truths, the evolutionary ethicist cannot offer (...) justifying reasons for a set of behaviours. I use these points to refute Waller's claims that the illusion of objectivity plays a dispensable role in Ruse's theory, that my critique of Ruse's Darwinian metaethics is built on a false dilemma, that there is nothing to be distressed about if morality is not objective, and that ethical beliefs are subject to a kind of causal explanation that undermines their objectivity in a way that scientific beliefs are not.

This introductory chapter discusses the philosophical and scientific arguments for free will skepticism and their implications--including the debate between Saul Smilansky's "illusionism," Thomas Nadelhoffer's "disillusionism," Shaun Nichols' "anti-revolution," and the "optimistic skepticism" of Derk Pereboom, Bruce Waller, Tamler Sommers, and others.
A distinction between the self and its superstructure, the ego, supports Mele's conclusions. The dynamics of the limbic system generates the self through behavior that is subject to societal observation. The rest of the brain contributes awareness that, by ingenious back-dating and rationalization, gives the ultimate in self-deception: the illusion of control of the self by its own derivative.
Hobbes is commonly taken as arguing that individuals are primarily motivated by a fear of violent death. In this paper, I argue that, for Hobbes, people come with a wide range of fears and desires; analyzing how to redirect these into the politically stabilizing fear of death is a central preoccupation of Leviathan. One of the main problems is managing what I call the “ontological illusion,” the constitutive human tendency to take presentations of the imagination as entities in the (...) world. I first assess the textual evidence for and against the violent death reading. I then offer a reading of Hobbes’s psychology that underscores the diversity of human affective states. In the third section, I assess Hobbes’s neglected chapter on demonology – theories of witchcraft – as demonstrating both the need to manage the ontological illusion and the Hobbesian strategy for doing so.

Examples of sensory illusion show the failure of the attempt of traditional sense-datum theory to account for something's phenomenally appearing to be F by postulating the existence of a sense-datum that is actually F. the Muller-Lyer Illusion cannot be explained by postulating two sensibly presented lines that actually have the lengths the physical lines appear to have. Illusions due to color contrast cannot be explained by postulating sense-data that actually have the colors the physical samples appear to have.
My aim in this article is to ascertain whether any of the interesting phenomena that Daniel Wegner discusses in The Illusion of Conscious Will (2002) falsify a certain hypothesis about intentional actions. Here is a rough, preliminary statement of the hypothesis: Whenever human agents perform an overt, intentional action, A, some intention of theirs is a cause of A. The hypothesis is refined in section 1. In section 2, I turn to this article's main question.
This commentary argues that the “illusion” to which Wegner refers in The Illusion of Conscious Will is actually the illusion that our conscious experience of mentally causing certain behaviors explains the behavior in question: It is not the subjective experience itself that is illusory, but the implied causal explanation. The experience of “mental effort” is cited as another example of this sort of illusion. Another significant example is the experience that properties of the representation of our (...) mental images are responsible for certain patterns of behavior observed in mental imagery experiments. Examples include the increase in reaction time found when details are reported from smaller images or when attention is switched between different places and features (imagined as further apart than they are) within a single image. These examples illustrate the nature of the “illusion” involved: It is the illusion that certain observed regularities occur because of the content of the experience, as opposed to the converse – that experience has the content it does because of what the person figures out would happen in the imagined situation.

: Vasubandhu, an advocate of the idealist Yogācāra school of Buddhism, argues that the nonexistence of external objects can be inferred from the appearance of nonexistent things in perceptual illusion. The idealist view and the argument from illusion are criticized by proponents of the realist Nyāya school on the grounds that illusory experience is parasitic upon veridical experience. The parasitism objection successfully defeats Vasubandhu's argument from illusion but fails to decisively disprove the idealist view because it remains (...) possible that each illusory experience gets its content from a previous illusory experience in an infinite chain.

On the one hand, it is often assumed that the Rubber Hand Illusion (RHI) is constrained by a structural body model so that one cannot implement supernumerary limbs. On the other hand, several recent studies reported illusory duplication of the right hand in subjects exposed to two adjacent rubber hands. The present study tested whether spatial constraints may affect the possibility of inducing the sense of ownership to two rubber hands located side by side to the left of the (...) subject's hand. We found that only the closest rubber hand appeared both objectively (proprioceptive drift) and subjectively (ownership rating) embodied. Crucially, synchronous touch of a second, but farther, rubber hand disrupted the objective measure of the RHI, but not the subjective one. We concluded that, in order to elicit a genuine RHI for multiple rubber hands, the two rubber hands must be at the same distance from the subject's hand/body. (shrink)
In the absence of an objective contingency, psychological studies have shown that people nevertheless attribute outcomes to their own actions. Thus, by wrongly inferring control in chance situations people appear to hold false beliefs concerning their agency, and are said to succumb to an illusion of control (IoC). In the current article, we challenge traditional conceptualizations of the illusion by examining the thesis that the IoC reflects rational and adaptive decision making. Firstly, we propose that the IoC is (...) a by-product of a rational uncertain judgment (“the likelihood that I have control over a particular outcome”). We adopt a Bayesian perspective to demonstrate that, given their past experience, people should be prone to ascribing skill to chance outcomes in certain situations where objectively control does not exist. Moreover, existing empirical evidence from the IoC literature is shown to support such an account. Secondly, from a decision-theoretic perspective, in many consequential situations, underestimating the chance of controlling a situation carries more costs than overestimating that chance. Thus, situations will arise in which people will incorrectly assign control to events in which outcomes result from chance, but the attribution is based on rational processes. (shrink)
In this commentary we discuss a predictive sensorimotor illusion, the size-weight illusion, in which the smaller of two objects of equal weight is perceived as heavier. We suggest that Grush's emulation theory can explain this illusion as a mismatch between predicted and actual sensorimotor feedback, and present preliminary data suggesting that the cerebellum may be critical for implementing the emulator.
Wegner's The Illusion of Conscious Will (2002) ignores an important aspect of the history of the concept: the determinism of Jonathan Edwards (1754) and the later response to this determinism by William James and others. We argue that Edwards's formulation, and James's resolution of the resulting dilemma, are superior to Wegner's.
Peter Woolcock, in Ruse's Darwinian Meta-Ethics: A Critique, argues that the subjectivist (nonobjectivist) Darwinian metaethics proposed by Michael Ruse (in Taking Darwin Seriously) cannot work, because the illusion of objectivity that Ruse claims is essential to morality breaks down when it is recognized as illusion, and there then remain no good reasons for acknowledging or following moral obligations. Woolcock, however, is mistaken in supposing that moral behaviour requires rational motivation. Ruse's Darwinian metaethical analysis shows why such objective support (...) for morality is neither plausible nor necessary; and when that is recognized, it can also be seen that Ruse's proposed illusion of moral objectivity is superfluous.

Berkeley and Helmholtz proposed different indirect mechanisms for size perception: Berkeley, that size was conditioned to various cues, independently of perceived distance; Helmholtz, that it was unconsciously calculated from angular size and perceived distance. The geometrical approach cannot explain size-distance paradoxes (e.g., moon illusion). The dorsal/ventral solution is dubious for close displays and untestable for far displays.
