David Chalmers is a prominent philosopher who has dedicated his career to analyzing the nature of conscious experience, most notably by defining the 'hard problem' of consciousness {fact:2, fact:9}. He argues that conscious experience is irreducible to physical facts {fact:3, fact:7, fact:13} and explores its relationship with functional organization and neural processes {fact:4, fact:10, fact:22}.

Moving Forward on the Problem of Consciousness - David Chalmers consc.net 15 facts
claimDavid Chalmers asserts that if neurons in a human brain were replaced with identically-functioning silicon chips, the subject would report that their qualia (conscious experience) remained unchanged.
claimDavid Chalmers argues that if conscious experience cannot be explained in terms of more basic entities, it must be considered irreducible, similar to the fundamental categories of space and time.
claimDavid Chalmers argues that the conditional assertion—if a functional isomorph of a human brain is possible, then it will have the same sort of conscious experience—is a safe bet.
claimDavid Chalmers predicts that early consciousness research will focus on isolating correlations between complex neuro/cognitive processes and familiar characteristics of conscious experience.
claimDavid Chalmers argues that any account of physical processing leaves a 'further question' regarding why structure and function are accompanied by conscious experience, necessitating a move beyond purely reductive explanation.
claimDavid Chalmers identifies the ultimate goal of consciousness research as the development of a fundamental psychophysical theory that explains the deep structure underlying high-level connections between neuro/cognitive processes and conscious experience.
claimDavid Chalmers and Warner agree that there exists a limited class of beliefs about conscious experience that cannot be wrong.
perspectiveBenjamin Libet critiques David Chalmers by stating that Chalmers relies on a 'behavioral' criterion for conscious experience rather than more convincing criteria like a subject's verbal report.
perspectiveDavid Chalmers proposes that the intrinsic properties underlying physical dispositions might be experiential properties or proto-experiential properties that constitute conscious experience.
perspectiveDavid Chalmers asserts that conscious experience is a phenomenon to be explained in its own right, rather than a concept postulated to explain other phenomena.
claimDavid Chalmers posits that the aspects of functional organization related to verbal reports, discrimination, and motor action may be among the primary determinants of conscious experience.
claimDavid Chalmers suspects that the residual non-structural properties of conscious experience will pose special problems for developing a formal language to describe them.
claimDavid Chalmers posits that moving from facts about physical structure and function to facts about conscious experience requires an extra step and a substantial principle to bridge the explanatory gap.
claimDavid Chalmers identifies the 'combination problem' (also known as the 'constitution problem') as the most difficult challenge in panpsychism, defined as the problem of how low-level proto-experiential properties constitute complex, unified conscious experiences.
claimDavid Chalmers defines the 'hard problem' of consciousness as the question of why the performance of a function is associated with conscious experience, noting that this remains a nontrivial question even after the function itself is explained.
The Conscious Mind - Wikipedia en.wikipedia.org 3 facts
perspectiveDavid Chalmers believes that an adequate theory of consciousness requires solving both the hard and easy problems, meaning science must discover not only brain states associated with conscious experience but also why and how those brain states are accompanied by experience.
claimDavid Chalmers argues that the 'hard problem' of consciousness is difficult because conscious experience is irreducible to lower-order physical facts.
claimDavid Chalmers supports the irreducibility of conscious experience by appealing to conceivability, arguing that conscious experience can always be 'abstracted away' from reductive explanations, as evidenced by the logical possibility of philosophical zombies, which are exact replicas of a person that lack conscious experience.
Hard problem of consciousness - Wikipedia en.wikipedia.org 3 facts
claimDavid Chalmers discussed Global workspace theory in his original paper on the hard problem of consciousness, arguing that while it provides a promising account of how information becomes globally accessible in the brain, it fails to answer why global accessibility gives rise to conscious experience.
claimDavid Chalmers argues that facts about neural mechanisms and behaviors do not lead to facts about conscious experience, as conscious experience constitutes further facts that are not derivable from facts about the brain.
claimDavid Chalmers posits that it is logically possible for a perfect physical replica of a human to exist without having any conscious experience, or to have a different set of experiences, such as an inverted visible spectrum.
David Chalmers - Wikipedia en.wikipedia.org 2 facts
claimDavid Chalmers argues that systems with the same functional organization at a fine enough grain (functionally isomorphic systems) will possess qualitatively identical conscious experiences.
claimDavid Chalmers proposed the 'dancing qualia' thought experiment, which concludes that a robotic brain functionally isomorphic to a biological one would possess the same conscious experiences, such as the same perception of color when seeing an object.

claimDavid Chalmers argues that while neuroscience suggests a lawful relationship between physical processes and conscious experience, these represent two irreducible ontic categories, meaning the responsible natural law cannot be entailed by physical law alone.
claimDavid Chalmers suggests that microphysical properties and their causal roles might be instantiations of protophenomenal 'quiddities', implying that the physical realm and its causal determination may supervene on or be constituted by the same protophenomenal properties that form conscious experience.
Consciousness and Cognitive Sciences journal-psychoanalysis.eu 1 fact
perspectiveThe authors of 'Consciousness and Cognitive Sciences' argue that explaining conscious experience requires a non-reductive explanation, a position they believe is heavier than most people, including David Chalmers, are willing to concede.
Panpsychism - Wikipedia en.wikipedia.org 1 fact
claimDavid Chalmers suggests that information which is physically realized is simultaneously phenomenally realized, implying that both regularities in nature and conscious experience are expressions of information's underlying character.
