Relationalism is the view that perception is partly constituted by external objects (McDowell 1994; Campbell 2002; Martin 2004). Faced with the hallucination argument, and unsatisfied with the standard disjunctivist reply, some ‘new wave’ relationalists explain away the possibility of hallucinations as mere illusions (Alston 1999; Watzl 2010; Ali 2018; Masrour 2020). In this paper, I argue that some of these illusions (as in Chalmers 2005; Ali 2018) are perceptions of internal objects which appear as external ones. Then, in response to (...) the obvious screening-off objection, I argue for a novel reply called ‘intrameralism’: roughly, external objects are ordinarily perceived because they gain internal parts—they ‘grow into the head’. The preceding hallucinations are thus ultimately explained away as a kind of perceptual synecdoche, in which internal parts appear as their (ordinarily perceived) external wholes. The paper concludes by addressing some objections. (shrink)

Experiential imagination consists in an imaginative projection that aims at simulating the experiences one would undergo in different circumstances. It has been traditionally thought to play a role in how we build our lives, engage with other agents, and appreciate art. Although some philosophers have recently expressed doubts over the capacity of experiential imagination to offer insight into the perspective of someone other than our present-selves, experiential imagination remains a much sought-after tool. This paper substantiates pessimism about the epistemological value (...) of these uses of experiential imagination by developing an embodied approach. Our thesis is that experiential imagination is _robustly embodied_ because the _sociohistorically situated_ body makes an irreducible contribution to the imaginative project, and that, as such, it is constrained by who we are as _concrete_ agents. We argue that experiential imagination is an embodied, virtual exploration of imagined scenarios that depends on our situated history of sensorimotor and affective interactions. We conclude that experiential imagination is much more limited than commonly acknowledged, as it can hardly be divorced from who we are and where we have been. (shrink)

Relationalism maintains that mind-independent objects are essential constituents of veridical perceptual experiences. According to the argument from hallucination, relationalism is undermined by perfect hallucinations, experiences that are introspectively indistinguishable from veridical perceptual experiences but lack an object. Recently, a new wave of relationalists have responded by questioning whether perfect hallucinations are possible: what seem to be perfect hallucinations may really be something else, such as illusions, veridical experiences of non-obvious objects, or experiences that are not genuinely possible. This paper argues (...) that however well new wave relationalism may handle brains in vats, drug users “seeing” pink elephants, and other extraordinary hallucinations, it struggles to accommodate mundane hallucinations, such as “hearing” your child cry out from the room down the hall when she is actually sound asleep or “feeling” vibrations on your thigh even when your phone isn't in your pocket. Mundane hallucinations are best explained as byproducts of noise in the perceptual system, and noise-induced hallucinations are resistant to the strategies that new wave relationalists deploy to explain away other hallucinations. Mundane hallucinations can thus underpin an especially powerful version of the argument from hallucination. (shrink)

The intuitive view that memories are characterized by a feeling of pastness, perceptions by a feeling of presence, while imagination lacks either faces challenges from two sides. Some researchers complain that the “feeling of pastness” is either unclear, irrelevant or isn’t a real feature. Others point out that there are cases of memory without the feeling of pastness, perception without presence, and other cross-cutting cases. Here we argue that the feeling of pastness is indeed a real, useful feature, and although (...) this feeling does not define memory ontologically, it is a characteristic marker which helps us easily categorise a mental state first-personally. We outline several cognitive features that underlie this experience, including the feeling of past accessibility, ergonomic significance, immersion, objectivity and mental strength. Our account is distinctly phenomenal, rather than doxastic, although our web of beliefs may contribute to this experience. (shrink)

For some, the states and processes involved in the realisation of phenomenal consciousness are not confined to within the organismic boundaries of the experiencing subject. Instead, the sub-personal basis of perceptual experience can, and does, extend beyond the brain and body to implicate environmental elements through one’s interaction with the world. These claims are met by proponents of predictive processing, who propose that perception and imagination should be understood as a product of the same internal mechanisms. On this view, as (...) visually imagining is not considered to be world-involving, it is assumed that world-involvement must not be essential for perception, and thus internalism about the sub-personal basis is true. However, the argument for internalism from the unity of perception and imagination relies for its strength on a questionable conception of the relationship between the two experiential states. I argue that proponents of the predictive approach are guilty of harbouring an implicit commitment to the common kind assumption which does not follow trivially from their framework. That is, the assumption that perception and imagination are of the same fundamental kind of mental event. I will argue that there are plausible alternative ways of conceiving of this relationship without drawing internalist metaphysical conclusions from their psychological theory. Thus, the internalist owes the debate clarification of this relationship and further argumentation to secure their position. (shrink)

When you hallucinate an object, you are not in the normal sort of concurrent causal sensory interaction with that object. It's standardly further inferred that the hallucinated object does not actually exist. But the lack of normal concurrent causal sensory interaction does not imply that there does not exist an object that is hallucinated. It might be a past‐perceived object. In this paper, I argue that this claim holds for at least some interesting cases of hallucination. Hallucinations generated by misleading (...) cues (e.g. ‘seeing’ Kanizsa triangles), hallucinations of Charles Bonnet Syndrome patients, and dreams are experiences of past‐perceived objects.

It has been pointed out that Sensorimotor Enactivism, a theory that claims that perception is enacted and brought about by movement, says very little about the neural mechanisms that enable perception. For the proponents of the predictive approach to Sensorimotor Enactivism, this is a challenge that can be met by introducing predictive processing into the picture. However, the compatibility between these theories is not straightforward. Firstly, because they seem to differ in their stand towards representations: while Sensorimotor Enactivism is said (...) to belong to the non-representational wing of cognitive science, predictive processing has a representational profile. And secondly, because they exhibit different explanatory strategies: while Sensorimotor Enactivism prioritizes the interactions of the embodied agent, predictive processing has internalist commitments. The aim of this paper is to address these concerns and show that a predictive approach to Sensorimotor Enactivism is viable. More specifically, I focus on the Free-Energy approach, a theory that falls within the ballpark of predictive processing. In this paper I argue for the following claims. I argue that both Sensorimotor Enactivism and the Free-Energy approach may be understood for some systems in representational terms. The non-representational reading of Sensorimotor Enactivism is not mandatory and neither is the representational reading of the Free-Energy approach. Sensorimotor Enactivism is, in this respect, compatible with both representational and non-representational interpretations of the FEA. So, the position towards representations of these frameworks should not stand in the way of a predictive approach to Sensorimotor Enactivism. I also show that the Free-Energy approach allows for an account that prioritizes the interaction of the embodied agent with the environment. This is the explanatory strategy followed by Sensorimotor Enactivism. To justify this strategy and following other proponents of Sensorimotor Enactivism, I argue that by referring to the interactions of the embodied agent a better account of the phenomena in question is provided. On this basis, I claim that Sensorimotor Enactivism and the Free-Energy approach are compatible in what concerns their explanatory strategy as well. Thus, making the case for the viability of the predictive approach to Sensorimotor Enactivism. (shrink)

According to a variety of recent ‘enactivist’ proposals, the material basis of conscious experience might extend beyond the boundaries of the brain and nervous system and into the environment. Clark (2009) surveys several such arguments and finds them wanting. Here I respond on behalf of the enactivist. Clarifying the commitments of enactivism at the personal and subpersonal levels and considering how those levels relate lets us see where Clark’s analysis of enactivism goes wrong. Clark understands the enactivists as attempting to (...) provide hypotheses about the subpersonal mechanisms underlying experience according to which those mechanisms contingently include portions of the environment. But understanding enactivism instead as involving a relational conception of experience at the personal level, with apparent implications for the location of the subpersonal mechanisms of experience, allows us to make better sense of the enactivist arguments, and make the case for conscious externalism.

We observe that approaches to intersubjectivity, involving mirror neurons and involving emulation and prediction, have eclipsed discussion of those same mechanisms for achieving coordination between the two hemispheres of the human brain. We explore some of the implications of the suggestion that the mutual modelling of the two situated hemispheres is a productive place to start in understanding the phylogenetic and ontogenetic development of cognition and of intersubjectivity.

When we dream, it is often assumed, we are isolated from the external environment. It is also commonly believed that dreams can be, at times, accurate, convincing replicas of waking experience. Here I analyse some of the implications of this view for an enactive theory of conscious experience. If dreams are, as described by the received view, “inactive”, or “cranially envatted” whilst replicating the experience of being awake, this would be problematic for certain extended conscious mind theories. Focusing specifically on (...) Alva Noë’s enactive view, according to which the vehicles of perceptual experience extend beyond the brain, I argue that dreams are a quandary. Noë’s view is that dreaming is consistent with enactivism because even if dreams are inactive and shut off from the external environment, they are not “full-blown” perceptual consciousness, and also, there is some reason to reject the inactive claim. However, this view rests on an unjustified and reductive account of dreams which is not supported... (shrink)

Dreams provide a compelling problem for sensorimotor enactivists like Alva Noë: they seem to replicate our perceptual experiences without sensorimotor interaction with distal sensory stimuli. Noë has responded by saying that dreams actually fail to replicate perceptual experiences in virtue of their lack of detail and stability. Noë's opponents have replied by pointing out that some dreams are richly detailed and stable, and that instability and a lack of detail in dreams can anyway be explained in terms of the underlying (...) neural activity. In this paper, I develop how the sensorimotor enactivist should respond: dreams fail to replicate perceptual experiences because they are exhausted by what shows up at a given moment in phenomenal consciousness, while perceptual experiences go beyond this to include everything accessible via sensorimotor exploration. This difference permeates all levels of experience, so that dreams can't even replicate perceptual experiences of simple shapes and colors. Further, unlike detail and stability, there are not obvious neural explanations of this phenomenal difference. (shrink)

What’s presented in our normal waking perceptual visual experiences feels present to us, while what we “see” in pictures and imagine does not. What about dreams? Does what we “see” in a dream feel present? Jennifer Windt has argued for an affirmative answer, for all dreams. But the dreams which flow from the brain’s registration of myoclonic twitches present a challenge to this answer. During these dreams motion-guiding vision is shut off, and, as Mohan Matthen has argued, motion-guiding vision seems (...) to be a key mechanism underlying the feeling of presence. I propose that the feeling of presence in fact involves two components: the feeling of immersion, and the feeling of availability for action. I suggest that only the feeling of availability for action derives from motion-guiding vision, and, hence, hypothesize that body-driven dreams lack this component to the feeling of presence. Finally, the distinction between these two varieties of presence has implications for measures of presence in virtual environments, as these measures can diverge over which of the two varieties they track.

In the extended mind literature, one sometimes finds the claim that there is no neural correlate of consciousness. Instead, there is a biological or ecological correlate of consciousness. Consciousness, it is claimed, supervenes on an entire organism in action. Alva Noë is one of the leading proponents of such a view. This paper resists Noë's view. First, it challenges the evidence he offers from neuroplasticity. Second, it presses a problem with paralysis. Third, it draws attention to a challenge from the (...) existence of metamers and visual illusions. (shrink)

Our eyes, bodies, and perspectives are constantly shifting as we observe the world. Despite this, we are very good at distinguishing between self-caused visual changes and changes in the environment: the world appears mostly stable despite our visual field moving around. This, it seems, also occurs when we are dreaming. As we visually investigate the dream environment, we track moving objects with our dream eyes, examine objects, and shift focus. These movements, research suggests, are reflected in the rapid movements or (...) saccades of our sleeping eyes. Do we really see the dream world in the same way that we see the real world? If we do, how could dreaming, usually assumed to be mind-generated hallucinations, replicate such an experience? This problem would be deflated if dreams are not hallucinations at all, but rather imagination, illusion or simply unrealistic. I argue that imagination and illusion views do not satisfactorily explain away the problem of vision and action in sleep. The imagination model is not a complete description of dreaming that is consistent with empirical research, and it is unlikely that the visual dream world is an illusion. Given that the dreaming visual experience is most likely active, hallucinatory, and at times a realistic world simulation, there are important implications for our understanding of visual perception and its relationship to movement. Evidence suggests that our dream eyes investigate the dream world as our waking eyes investigate the waking world. If changes to the unconsciously generated dream environment are perceived as external and unintentional while dream body movements are perceived as self-generated and intentional, current theory of visual perception may have to be expanded to account for how the dreaming mind generates a stable world in which we track and visually explore mind-generated objects.

The experience of skilled action occurs in dreams if we take dream reports at face value. However, what these reports indicate requires nuanced analysis. It is uncertain what it means to perform any action in a dream whatsoever. If skilled actions do occur in dreams, this has important implications for both theory of action and theory of dreaming. Here, it is argued that since some dreams generate a convincing, hallucinated world where we have virtual bodies that interact with virtual objects, (...) there is a sense in which we can perform virtual actions. Further, we can also perform skilfully, although not all apparent skilful performance is as it seems. Since the dream world is generated by the dreamer’s own mind, it can be difficult to determine whether the dream world simply allows goals to be achieved without the abilities that would be required in a similar waking scenario. Because of this, individual dream reports alone are insufficient to determine what skills are demonstrated in a particular dream. However, taken with evidence from REM sleep behaviour disorder, incompetent dreams, lucid dreams and motor-skill practise, it is likely that skilled virtual dream performance at times involves both opportunity for virtual behaviour and the display of competence. Evidence from cognitive science suggests that dreamers can also lose competence through forgetting and other cognitive incapacities but, more surprisingly, it is possible to gain abilities in a robust sense, consistent with the idea that some dreams, at least, are virtual realities rather than imagination.

This paper explores the possibility of a neuroscientific explanation of consciousness, and what such an explanation might look like. More specifically, I will be concerned with the claim that for any given experience there is neural representational system that constitutes the minimal supervenience base of that experience. I will call this hypothesis the minimal supervenience thesis. I argue that the minimal supervenience thesis is subject to two readings, which I call the localist and holist readings. Localist theories seek to identify (...) the minimal supervenience base for specific experiences. They sideline questions about the nature of creature consciousness, treating the neural basis of creature consciousness as merely a causally necessary background condition for a particular conscious experience. Holists on the other hand prioritise creature consciousness and argue that we can only account for particular states of consciousness in the context of an account of creature consciousness. I argue that any scientific explanation of consciousness must account for what I will call a minimal sense of self that is intrinsic to every conscious state. Holist theories are best able to accommodate this feature. I end by arguing that the Dynamic Sensorimotor account of consciousness can be combined with a holist account of the neural basis of consciousness. Such a combination of views corrects for the opposition to the minimal supervenience thesis found in some prominent defenders of the DSM account . It also provides a framework for developing a neuroscientific account of the minimal sense of self. (shrink)

Dieser Artikel macht von der Möglichkeit Gebrauch, das Phänomen des Bewusstseins neurowissenschaftlich zu erklären, und geht der Frage nach, wie eine solche Erklärung wohl auszusehen hätte. Der Verfasser widmet sich konkret der These, dass jeder Erfahrung ein repräsentatives neurales System zugrunde liegt, das als Supervenienzgrundlage dieser Erfahrung dient. Diese Hypothese wird im weiteren Verlauf als minimale Supervenienz-These bezeichnet. Nach Meinung des Autors kann diese These auf zweierlei Weisen verstanden werden; dementsprechend ist von einer lokalistischen und einer holistischen Lesart die Rede. (...) Lokalistische Theorien versuchen, die minimale Supervenienzgrundlage einer spezifischen Erfahrung zu ermitteln, während sie Fragen über die Natur des Bewusstseins von Lebewesen beiseite lassen und die Neuralbasis des Bewusstseins lediglich als kausal-notwendige Hintergrundvoraussetzung für eine partikuläre Bewusstseinserfahrung werten. Holisten hingegen räumen dem Bewusstsein von Lebewesen Vorrang ein und behaupten, dass partikuläre Bewusstseinszustände nur im Rahmen von Deutungen ebendieses Bewusstseins erklärt werden können. Nach Meinung des Autors muss jegliche wissenschaftliche Deutung des Bewusstseins jenem Faktor Rechnung tragen, den er als minimale Wahrnehmung des Selbst bezeichnet und das jedem Bewusstseinszustand intrinsisch ist. Holistische Theorien sind am besten geeignet, diesen Umstand zu verändern. Der Artikel schließt mit der These, dass die sog. Dynamisch-Sensomotorische Deutung des Bewusstseins mit der holistischen Erklärung der Neuralbasis des Bewusstseins kombiniert werden kann. Eine solchermaßen kombinierte Sichtweise korrigiert den Widerspruch bezüglich der These von der minimalen Supervenienz, die bei einigen prominenten Befürwortern der DSM These zu finden ist. Sie ermöglicht ebenfalls einen Rahmen für die Entwicklung einer neurowissenschaftlichen Deutung der These von der minimalen Wahrnehmung des Selbst. (shrink)
