Facing up to the problem of consciousness
Abstract
To make progress on the problem of consciousness, we have to confront it directly. In this paper, I first isolate the truly hard part of the problem, separating it from more tractable parts and giving an account of why it is so difficult to explain. I critique some recent work that uses reductive methods to address consciousness, and argue that such methods inevitably fail to come to grips with the hardest part of the problem. Once this failure is recognized, the door to further progress is opened. In the second half of the paper, I argue that if we move to a new kind of nonreductive explanation, a naturalistic account of consciousness can be given. I put forward my own candidate for such an account: a nonreductive theory based on principles of structural coherence and organizational invariance, and a double-aspect theory of information.

In contrast to GNWT, IIT, RPT, and PP/NREP all primarily try to address the Hard Problem.
“Thus, in contrast to GNWT, the other theories (IIT, RPT, and PP/NREP; for dendritic integration theory (DIT), see below) all primarily try to address the ''Hard Problem, 1 ''”

To truly explain consciousness would require solving what Chalmers calls the hard problem of consciousness.

Classical frameworks have not resolved how subjective, unified, first-person experience emerges from distributed biological computation.
“Classical frameworks have elucidated the mechanisms by which neurons communicate, networks oscillate, and cognitive processes unfold, yet these accounts have not resolved how subjective, unified, first-person experience emerges from distributed biological computation.”

The mathematical structures underlying quantum physics possess an expressive power well suited to modelling cognition at levels of complexity where classical architectures saturate [1].
“They do not imply that the brain literally implements tensor contractions, but they demonstrate that the mathematical structures underlying quantum physics possess an expressive power well suited to modelling cognition at levels of complexity where classical architectures saturate [1].”

This provides good evidence that consciousness is complex, with complex causes, and is not simply caused by one fundamental, or psychic, force of nature.
“This provides good evidence that consciousness is complex, with complex causes, and is not simply caused by one fundamental, or psychic, force of nature as some have claimed (Chalmers, 1996; Velmans, 2008; Skrbina, 2009; Goff et al., 2017).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
