The hard problem of consciousness has been a perennially vexing issue for the study of consciousness, particularly in giving a scientific and naturalized account of phenomenal experience. At the heart of the hard problem is an often-overlooked argument, which is at the core of the hard problem, and that is the structure and dynamics (S&D) argument. In this essay, I will argue that we have good reason to suspect that the S&D argument given by David Chalmers rests on a limited conception of S&D properties, what in this essay I’m calling extrinsic structure and dynamics. I argue that if we take recent insights from the complexity sciences and from recent developments in Integrated Information Theory (IIT) of Consciousness, that we get a more nuanced picture of S&D, specifically, a class of properties I’m calling intrinsic structure and dynamics. This I think opens the door to a broader class of properties with which we might naturally and scientifically explain phenomenal experience, as well as the relationship between syntactic, semantic, and intrinsic notions of information. I argue that Chalmers’ characterization of structure and dynamics in his S&D argument paints them with too broad a brush and fails to account for important nuances, especially when considering accounting for a system’s intrinsic properties. Ultimately, my hope is to vindicate a certain species of explanation from the S&D argument, and by extension dissolve the hard problem of consciousness at its core, by showing that not all structure and dynamics are equal.

Malcolm Riddoch investigates the relationship between the auditory imagination and our perception of sound. He states that, from a physical perspective, both imaginary and externally stimulated sound would seem to be the product of neurological processes. From a phenomenological perspective, however, phenomenal sound is fundamentally something that is heard. This apparent paradox leads Riddoch, via the “hard problem of consciousness,” to present and discuss a number of different forms and understandings of “sound” and to eventually posit that the sounds themselves—imagined or externally stimulated—are “nonphysical phenomena disclosed in the lived experience of hearkening to the meaningful sounds one hears in the world.”

This chapter shows that global-workspace theory can be developed into a satisfying, fully reductive explanation of phenomenal consciousness. It shows how globally broadcast nonconceptual content enables higher-order thoughts about that content, where those thoughts can lack conceptual connections with physical, functional, or representational facts. As a result, zombies are conceivable and an (epistemic) explanatory gap is opened up. But the thoughts in question can themselves be given a fully naturalistic explanation. Hence all of the facts involved in consciousness can be fully explained. The chapter defends the reality of the phenomenal concepts needed to make this account work, and replies to a dilemma for the account proposed by David Chalmers.

Coronary computed tomography angiography (CCTA) has been recently evaluated for its ability to assess coronary plaque characteristics, including plaque composition. Identification of the relationship between plaque composition by CCTA and patient clinical presentations may provide insight into the pathophysiology of coronary artery plaque, thus assisting identification of vulnerable plaques which are associated with the development of acute coronary syndrome. CCTA-generated 3D visualizations allow evaluation of both coronary lesions and lumen changes, which are considered to enhance the diagnostic performance of CCTA. The purpose of this review is to discuss the recent developments that have occurred in the field of CCTA with regard to its diagnostic accuracy in the quantitative assessment of coronary plaques, with a focus on the characterization of plaque components and identification of vulnerable plaques.

In his bookThe Conscious MindDavid Chalmers introduced a now-familiar distinction between the hard problem and the easy problems of consciousness. The easy problems are those concerned with the question of how the mind can process information, react to environmental stimuli, and exhibit such capacities as discrimination, categorization, and introspection (Chalmers 1996, 4; 1995, 200). All of these abilities are impressive, but they are, according to Chalmers, not metaphysically baffling, since they can all be tackled by means of the standard repertoire of cognitive science and explained in terms of computational or neural mechanisms. This task might still be difficult, but it is within reach. In contrast, the hard problem — also known astheproblem of consciousness (Chalmers 1995, 201) — is the problem of explaining why mental states have phenomenal or experiential qualities. Why is it like something to ‘taste coffee,’ to ‘touch an ice cube,’ to ‘look at a sunset,’ etc.? Why does it feel the way it does? Why does it feel like anything at all?

The article presents an overview of the key arguments of Terrence Deacon's theory of how mind emerged from matter. Deacon’s emergentism is analyzed as a way of refocusing the «hard problem» of consciousness. He suggests considering the phenomenon of consciousness as a dynamic coupling of mutually constraining processes. Such coupling is the defining feature of the subjective self and other teleodynamic phenomena. So self cannot be found as something embodied in existing material substrates. Consciousness is not present in such substrates themselves, but in the way different processes unfolding in these substrates constrain each other. Deacon shows that even looking at the simplest forms of life (autogens) one can observe that in them each part, interacting with other parts, creates the whole, and the whole as a synergetic complex makes possible the reproduction of its parts. The same principle underlies the organization of subjective consciousness, as subjective consciousness is hierarchically entangled with other levels of sentience. Thus, Deacon's emergentism is an attempt to take seriously the problem of the interrelation of spirit and matter by not simply to disregarding explanations that refer to the spiritual substance, but by offering the models of consciousness, sentience and purposiveness that could convincingly solve fundamental questions about the nature of consciousness in an alternative way. It is also an attempt to avoid the «naturalistic dualism» of David Chalmers, which involves splitting material information into physical and phenomenal aspects. According to Deacon, in explaining subjective self, one can do without both Cartesian spiritual substance and Chalmers' phenomenal information, but then what is necessary is to acknowledge the significance of absential phenomena (the phenomena that are intrinsically existing in relation to something missing, separate or nonexistent).

Emotions are important cognitive faculties that enable animals to behave intelligently in real time. The author argues that many important current and future applications of autonomous robots will require them to have a rich emotional repertoire, but this raises the question of whether it is possible for robots to experience their emotions consciously, as people do. Under what conditions would phenomenal experience of emotions be possible for robots? This is, in effect, the “hard problem” of robot emotions. This paper outlines a scientific approach to the question grounded in experimental neurophenomenology.

Abstract For the materialist, the hard problem is fundamentally an explanatory problem. Solving it requires explaining why the relationship between brain and experience is the way it is and not some other way. We use the tools of the interventionist theory of explanation to show how a systematic experimental project could help move beyond the hard problem. Key to this project is the development of second-order interventions and invariant generalizations. Such interventions played a crucial scientific role in untangling other scientific mysteries, and we suggest that the same will be true of consciousness. We further suggest that the capacity for safe and reliable self-intervention will play a key role in overcoming both the hard and meta-problems of consciousness. Finally, we evaluate current strategies for intervention, with an eye to how they might be improved.

What is consciousness? What does it do? Could we have evolved without it? ‘Why the mystery?’ considers the definition of consciousness and how psychologists, neuroscientists, and philosophers have tried to explain it. From the Cartesian dualism of René Descartes to the ‘hard problem’ of consciousness, a phrase coined in 1994 by the Australian philosopher David Chalmers, and the question ‘What is it like to be a bat?’ of American philosopher Thomas Nagel, it is shown that there is no generally agreed definition of consciousness. Subjectivity (or phenomenality), qualia, and the ideas of philosopher Daniel Dennett are also discussed.

Abstract In this article, we look at the hard problem of consciousness from the perspective of process metaphysics. We thereby identify three problematic premises of the problem that pertain to the constitution of consciousness and its causal relation to the world. We argue for the necessity of re-thinking the corresponding phenomena in terms of internally-structured processes. The hard problem would then cease to be an insurmountable obstacle to a science of consciousness. Furthermore, this line of reasoning is shown to be continuous with philosophical projects from the early 20th century that preceded the contemporary philosophy of mind. Specifically, we investigate the relationship of parts and wholes, and translate metaphysical problems of consciousness into mereological language. Despite this being a philosophical project, we frequently note and discuss links to the empirical sciences, in particular those of quantum mechanics, systems theory and the embodied cognition framework.
