Phenomenal Consciousness: A Naturalistic Theory
Abstract
How can phenomenal consciousness exist as an integral part of a physical universe? How can the technicolour phenomenology of our inner lives be created out of the complex neural activities of our brains? Many have despaired of finding answers to these questions; and many have claimed that human consciousness is inherently mysterious. Peter Carruthers argues, on the contrary, that the subjective feel of our experience is fully explicable in naturalistic (scientifically acceptable) terms. Drawing on a variety of interdisciplinary resources, he develops and defends a novel account in terms of higher-order thought. He shows that this can explain away some of the more extravagant claims made about phenomenal consciousness, while substantively explaining the key subjectivity of our experience. Written with characteristic clarity and directness, and surveying a wide range of extant theories, this book is essential reading for all those within philosophy and psychology interested in the problem of consciousness.

The UAL approach is not compatible with higher-order thought (HOT) theories of the type defended by Carruthers (2000), Rosenthal (2005) and LeDoux (2019).
“First, the UAL approach, while compatible with many specific theories about the nature of consciousness, is not compatible with higher-order thought (HOT) theories of the type defended by Carruthers (2000), Rosenthal (2005) and LeDoux (2019).”

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.
