A main goal of the neuroscience of consciousness is: find the neural correlate to conscious experiences (NCC). When have we achieved this goal? The answer depends on our operationalization of “NCC.” Chalmers (2000) shaped the widely accepted operationalization according to which an NCC is a neural system with a state which is minimally sufficient (but not necessary) for an experience. A deeper look at this operationalization reveals why it might be unsatisfactory: (i) it is not an operationalization of a correlate (...) for occurring experiences, but of the capacity to experience; (ii) it is unhelpful for certain cases which are used to motivate a search for neural correlates of consciousness; (iii) it does not mirror the usage of “NCC” by scientists who seek for unique correlates; (iv) it hardly allows for a form of comparative testing of hypotheses, namely experimenta crucis. Because of these problems (i–iv), we ought to amend or improve on Chalmers's operationalization. Here, I present an alternative which avoids these problems. This “NCC2.0” also retains some benefits of Chalmers's operationalization, namely being compatible with contributions from extended, embedded, enacted, or embodied accounts (4E-accounts) and allowing for the possibility of non-biological or artificial experiencers.

How to model non-egoic experiences – mental events with phenomenal aspects that lack a felt self – has become an interesting research question. The main source of evidence for the existence of such non-egoic experiences are self-ascriptions of non-egoic experiences. In these, a person says about herself that she underwent an episode where she was conscious but lacked a feeling of self. Some interpret these as accurate reports, but this is questionable. Thomas Metzinger, Rocco Gennaro, and Charles Foster have hinted (...) at the self-defeating nature of such statements if we take them to be genuine reports: Apparently, the reporter explicitly denies her existence during the selfless experience, but implicitly affirms her existence as a witness to that selfless experience in order to give a first-person report about it. So the content of such a report conflicts with the pragmatics of reporting. If all self-ascriptions of non-egoic experiences are self-defeating in this way, then they cannot count as evidence for the existence of non-egoic experiences. Here, I map out why such strong conclusions do not directly follow: What look like self-ascriptions of non-egoic experiences may occur for a number of reasons. Only some explanations for such utterances rely on a change in consciousness. Of those that do rely on a change in consciousness, only one is incoherent. But its alternatives do not lead to contradictions. I argue that the most likely change in phenomenality that leads to self-ascriptions of non-egoic experiences is not one where a felt self disappears, but where it expands. (shrink)

In recent years, the science and the philosophy of consciousness has seen growing interest in structural questions about consciousness. This is the Editorial Introduction for a special volume for Philosophy and the Mind Sciences on “Structuralism in Consciousness Studies.”.

Chris Letheby argues in Philosophy of Psychedelics that psychedelics and knowledge are compatible. Psychedelics may cause new mental states, some of which can be states of knowledge. But the influence of psychedelics is largely psychological, and not all psychological processes are epistemic. So I want to build on the distinction between processes of discovery and processes of justification to criticise some aspects of Letheby’s epistemology of psychedelics. Unarguably, psychedelics can elicit processes of discovery. Yet, I hold, they can hardly contribute (...) either to the epistemic success of a mental state or to processes of justification. As these are central for a mental state to be a state of knowledge and are largely uninfluenced by psychedelics, the contributions of psychedelics to knowledge are rather indirect than direct: The heavy epistemic lifting—what turns a mental state into a state of knowledge—is, in its epistemic aspects, independent of any influence of psychedelics on our psyche. Positively, while the mechanisms that Letheby points to need not be associated with knowledge, they do provide crucial epistemic benefits if they are associated with understanding. Reading them as facilitating understanding covers also those cases where truth or justification is missing and thereby provides a broader picture of the epistemic contributions of psychedelics.

Ground Representationism is the position that for each phenomenal feature there is a representational feature that accounts for it. Against this thesis, Ned Block (The Puzzle of Phenomenal Precision, 2015) has provided an intricate argument that rests on the notion of “phenomenal precision”: the phenomenal precision of a percept may change at a different rate from its representational counterpart. If so, there is then no representational feature that accounts for a specific change of this phenomenal feature. Therefore, Ground Representationism cannot (...) be generally true. -/- Although the notion of phenomenal precision is intuitive, it is admittedly in need of clarification. Here I reconstruct Block’s argument by suggesting a way of estimating phenomenal precision that is based on the assumption that parts of perceptual wholes can share phenomenal features independently of their place in the whole. Understood like this, the overall argument shows what it is supposed to show. -/- A more thorough look at the notion of phenomenal precision suggests tension with Block’s other work: in order to be non-trivial, we have to accept that some of our phenomenality is not concrete, but only generic. Such “solely generic phenomenology”, however, is a position mainly held by opponents to Block’s Access- vs. Phenomenal Consciousness-distinction. Interpreting phenomenal imprecision as constituted by introspective imprecision does not suffice as a way out. It seems that phenomenal precision is either trivial, self-contradictory, or incompatible with Block’s position elsewhere. So some additional elucidation on this crucial notion is needed. (shrink)

Sceptics vis-à-vis introspection often base their scepticism on ‘phenomenological disputes’, ‘introspective disagreement’, or ‘introspective disputes’ (Kriegel, 2007; Bayne and Spener, 2010; Schwitzgebel, 2011): introspectors massively diverge in their opinions about experiences, and there seems to be no method to resolve these issues. Sceptics take this to show that introspection lacks any epistemic merit. Here, I provide a list of paradigmatic examples, distill necessary and sufficient conditions for IDs, present the sceptical argument encouraged by IDs, and review the two main strategies (...) to reject such a scepticism. However, both types of strategies are unsatisfactory. In order to save introspection from the looming sceptical threat, I advocate a deflationary strategy, based on either an ‘Argument from Perceptual Kinship’ or an ‘Argument from Ownership’. In the end, there cannot be any genuine IDs, for nothing can fulfil the reasonable conditions for IDs. What looks like IDs may instead be indicators of phenomenal variation. Debates that look like IDs may then arise even if introspection were a perfect method to know one’s mind. Thus, scepticism vis-à-vis introspection based on IDs rests on shaky grounds. (shrink)

There is tension between commonly held views concerning phenomenal imagery on the one hand and our first-person epistemic access to it on the other. This tension is evident in many individual issues and experiments in philosophy and psychology (e.g. inattentional and change blindness, the speckled hen, dream coloration, visual periphery). To dissolve it, we can give up either (i) that we lack full introspective access to the phenomenal properties of our imagistic experiences, or (ii) that phenomenal imagery is fully determined, (...) or (iii) that phenomenal imagery does not exist. Which option is preferable? I explore the feasibility of option (ii) in more details by distinguishing between di erent kinds of indeterminacy. One of the most often proclaimed versions of indeterminacy is tied to Representationalism. However, I argue that in this context, Representationalism appears to be the least satisfying option, for which I give ten reasons. By abduction, we should reject Representationalism in favour of (i) or (iii)—the most parsimonious option being eliminativism, and the most conservative being the rejection of privileged access. The decision between these two, however, should be made on a case-by-case basis, depending on which is most adequate given the data. I illustrate this with the comparison between visual agnosia and Charles-Bonnet-Syndrome. (shrink)

Is a phenomenal pain a conscious primitive or composed of more primitive phenomenal states? Are pain experiences necessarily or only contingently unpleasant? Here, I sketch how to answer such questions concerning intra-phenomenal metaphysics using the example of pain and unpleasantness. Arguments for a symmetrical metaphysical independence of phenomenal pain and unpleasant affect are presented, rejecting a composite view like the IASP definition and dimensional views. The motivating intuition of these views is explained by common binding mechanisms in consciousness and characterized (...) as fallacious if generalized. There are, however, underlying commonalities between pain perception and unpleasant affect, e.g. formal content or evolutionary ancestry. (shrink)

Can we find necessary and sufficient conditions for a mental state to be a pain state? That is, does pain have a nature? Or is the term ‘pain’ ambiguous? I argue here that our expression ‘pain’ lacks necessary use conditions if one considers a range of contexts. As use conditions constrain the reference class, I argue that ‘pain’ does not refer to a natural category, but binds together a bunch of loosely resembling phenomena. This leads to problems for scientific and (...) clinical discourse. To solve these, a method of explication is suggested, based on a discursive combination between analysis of first-person reports and theories of natural science. Lastly, I consider the ethical implications of this ambiguity that lead to a reformulation of the goal of pain science: Not alleviation of all pains ought to be our goal, but only manipulation of conscious and negatively emotionally charged pains.

Thomas Metzinger has diagnosed the need for a Bewusstseinskultur, a ‘consciousness culture’: a culturally implemented way in which a society as a whole engages with the dawning natural science of consciousness, with phenomenal experiences themselves, and with our increasing capability to manipulate them. A Bewusstseinskultur is an achievement, built by a society-wide orientation on empirical evidence, thorough scientific theorizing and rational deliberation. It affects a broad range of issues from animal ethics, drug policy, end-of-life-care, and robo-ethics to post-humanism. However, this (...) notion has not yet been presented in English, and is so far unconnected to other discussions in philosophy. Here, I remedy this: I present Metzinger's notion of a Bewusstseinskultur and connect it to discussion on transformative experiences, Parfit's meta-hedonic states, and the Access vs. Phenomenal Consciousness distinction.

Unter einigenWissenschaftlern ist die Vorstellung verbreitet, dass Paradoxien Anzeichen von Fortschritt sein können. Es ist jedoch unklar, wie dies zu deuten ist. Dieser Essay stellt ein subjekt-relatives Verständnis von Paradoxikalität vor, das Paradoxien als »Dissonanzen der Zustimmung« (Rescher 2001) charakterisiert und dadurch erlaubt, sie als Katalysator wissenschaftlichen Fortschritts zu rekonstruieren: Durch ihre Struktur haben Problemstellungen in Form von Paradoxien wenigstens fünf fortschrittsfördernde Eigenschaften, die sie Problemstellungen in Form von Fragen voraushaben. Dadurch können Paradoxien als Angelpunkte theoretischen Fortschritts gesehen werden. Dies (...) legt eine Forderung nahe: Wenn wir theoretischen Fortschritt in den Wissenschaften fördern wollen, so sollten wir den Bau von Paradoxien aktiv verfolgen, gemäß dem Credo: Progress by Paradox!

At least two distinct modeling frameworks contribute to the view that mind and brain are Bayesian: Bayesian Rational Analysis (BRA) and Hierarchical Predictive Coding (HPC). What is the relative contribution of each, and how exactly do they relate? In order to answer this question, we compare the way in which these two modeling frameworks address different levels of analysis within Marr’s tripartite conception of explanation in cognitive science. Whereas BRA answers questions at the computational level only, many HPC-theorists answer questions (...) at the computational, algorithmic, and implementational levels simultaneously. Given that all three levels of analysis need to be addressed in order to explain a behavioral or cognitive phenomenon, HPC seems to deliver more complete explanations. Nevertheless, BRA is well-suited for providing a solution to the dark room problem, a major theoretical obstacle for HPC. A combination of the two approaches also combines the benefits of an embodied-externalistic approach to resolving the dark room problem with the idea of a persisting evidentiary border beyond which matters are out of cognitive reach. For this reason, the development of explanations spanning all three Marrian levels within the general Bayesian approach may require combining the BRA and HPC modeling frameworks. (shrink)

I argue that the understanding of "pain" as presented in the official medical definition by the IASP is ambiguous and likely a cluster concept.

So called “shapes of opposition”—like the classical square of opposition and its extensions—can be seen as graphical representations of the ways in which types of statements constrain each other in their possible truth values. As such, they can be used as a novel way of analysing the subject matter of disputes. While there have been great refinements and extensions of this logico-topological tool in the last years, the broad range of shapes of opposition are not widely known outside of a (...) circle of specialists. This ignorance may lead to the presumption that the classical square of opposition fits all disputes. A broader view, which takes expanded shapes of opposition into account, may come to a more nuanced appraisal of possible disputes. Once we take other shapes of opposition into account, some alleged disputes may turn out to be Scheindisputes. In order to do the wide range of linguistic expressions justice and to differentiate Scheindisputes from real ones, a broader view is advised. To illustrate this point, I discuss the notion of “introspective disputes”. These are commonly reconstructed as obeying the square, but are more aptly reconstructed with a more complex octagon. If we reconstruct these disputes based on Buridan’s octagon, it becomes obvious that “introspective disputes” are likely Scheindisputes. (shrink)

This special issue focuses on the Philosophy of Psychedelics by Chris Letheby in the form of a book symposium. Introduced by Matthew Johnson, Letheby presents the main claims of this book that explores the apparent conflict between psychedelic therapy and naturalism in a préci​s.​​ Seven contributions criticize, expand or comment on Letheby's arguments, focusing either on his proposed mechanism for psychedelic therapy or on the epistemic implications. The symposium concludes with Letheby’s replies to these commentaries.

This symposium focuses on Thinking and Perceiving by Dustin Stokes (2021), published by Routledge. In his précis, Stokes (2023a) provides an overview of the key arguments of his book, which lead to a new descriptive and normative account of the relationship between cognition and perception. Four commentaries examine the scope and implications of this account. Zoe Drayson (2023) and Christopher Mole (2023) examine the epistemological force of Stokes’s claims about the organisation of the human mind. Furthermore, the implications of philosophical (...) and empirical research on object recognition are discussed by Aleksandra Mroczko-Wasowicz (2023) and on perceptual learning by Zed Adams (2023). The symposium concludes with a reply by Stokes to these commentaries (Stokes, 2023b). (shrink)

In this article, I focus on what is we know when we know pain or that someone is in pain. I argue that claims of knowledge about pains are problematic because of the complex nature of the phenomenon and because of "pain" is a cluster concept.

In this article, we offer a systematic description of intermedia relations across music, literature, the visual arts, and film. Beginning with some general reflections on materiality and medium in these diverse fields of art, we then offer various examples consisting of two media (e.g. music film, song, images in writing). We pursue the question if, and how, one of the two media may take priority over the other. In our conclusion, we deal with „intermedia relations in monomediality“. This section focuses (...) on artistic representations made in one medium, but based on reflections on another medium. For instance, this is the case when a novelist writes about a picture without having this picture reprinted in the text. (shrink)

During performative artistic projects in Ambient Art, both space and structures of embodiment are constituted. I illustrate this thesis with examples of performative works in music, theatre and art, in order to analyze the transdisciplinary phenomenon of Ambient Art as a complex structure. My point of departure is a model of lived space in which the bodily enactment in the performative artwork produces place and, vice versa, the place of the artwork determines the active body as an immersive aesthetic experience.
