Consciousness and qualia are intrinsically linked in the philosophy of mind, where qualia are defined as the subjective, phenomenal character or 'qualitative feels' of conscious states {fact:16, fact:23, fact:24, fact:28}. This relationship is central to the 'Hard Problem of Consciousness,' which explores whether physical brain states can account for these subjective experiences {fact:4, fact:18, fact:21, fact:27}.

claimDavid Chalmers defines consciousness as the phenomenal character of conscious states or qualia, which are aspects of reality that cannot be described in terms of physical properties.
claimDavid Chalmers argues that awareness is necessary to explain human knowledge of qualities, meaning the awareness problem is fundamentally linked to the subject problem of how consciousness or qualia result from a collective of smaller entities.
claimDavid Chalmers defines phenomenal qualities, or "qualia," as the qualitative feels or associated qualities of experience that make a mental state conscious.
quote“We can say that a being is conscious if there is something it is like to be that being, to use a phrase made famous by Thomas Nagel. Similarly, a mental state is conscious if it has a qualitative feel—an associated quality of experience. These qualitative feels are also known as phenomenal qualities, or qualia for short. The problem of explaining these phenomenal qualities is just the problem of explaining consciousness. This is the really hard part of the mind–body problem”

Consciousness (Stanford Encyclopedia of Philosophy/Fall 2025 ... plato.stanford.edu 3 facts
perspectiveThe Multiple Drafts Model (MDM) is representationalist because it analyzes consciousness in terms of content relations, and it rejects the existence of qualia as a means to distinguish conscious from nonconscious states.
perspectiveProponents of representationalism, including Dennett (1990), Lycan (1996), and Carruthers (2000), are motivated by the goal of accommodating facts about consciousness within a physicalist framework without requiring the existence of qualia or non-representational mental properties.
perspectiveModest eliminativists, such as Dennett (1990, 1992) and Carruthers (2000), do not reject the notion of consciousness entirely but take issue with specific features like qualia, the conscious self, or the 'Cartesian Theater' where the temporal sequence of conscious experience is internally projected.

perspectiveJG argues that spatial perception is a prerequisite for qualia, and therefore artificial intelligence, which lacks spatial existence, is inherently incapable of consciousness.
referenceMaurice Merleau-Ponty (1962) posited that space is not a neutral stage for physical events, but rather a perceptual construct within consciousness, analogous to the qualia of redness.
referenceThomas Nagel (1974) identified that discussions on consciousness have traditionally focused on the emergence of qualia within the brain's neural architecture, a phenomenon often referred to as the alchemy of qualia.
The function(s) of consciousness: an evolutionary perspective frontiersin.org 3 facts
perspectiveLacalli conjectures that a key function of consciousness, related to both memory and distinguishable qualia, is to assign meaning to sensory inputs.
claimFor consciousness to be adaptive in influencing behavioral decision-making, it must convey information about reality, which necessitates that the qualia of experience be distinguishable in a meaningful way.
claimConsciousness allows information related to hazards of the real world to be encoded in the genome within the assembly instructions for neural circuits responsible for phenomenal experience, or qualia.

claimThe 'psychion' is a subatomic particle of the absolute vacuum that possesses phenomenal properties (qualia), informational content of recycled consciousness, mass, charge, and spin.
claimA 'psychion' is defined as the elementary particle of consciousness, representing the resonating channel or frequency wavelength of individuated consciousness with emergent qualia.

claimProposals made in the 2020s suggest that a cognitively inspired form of representationalism can reconcile neuroscience and the philosophy of mind by bridging gaps regarding concepts such as intentionality, emergence, consciousness, and qualia.
quoteWolfgang Fasching stated: 'Today there is a strong tendency to simply equate consciousness with the qualia. Yet there is clearly something not quite right about this. The "itchiness of itches" and the "hurtfulness of pain" are qualities we are conscious of. So philosophy of mind tends to treat consciousness as if it consisted simply of the contents of consciousness (the phenomenal qualities), while it really is precisely consciousness of contents, the very givenness of whatever is subjectively given. And therefore the problem of consciousness does not pertain so much to some alleged "mysterious, nonpublic objects", i.e. objects that seem to be only "visible" to the respective subject, but rather to the nature of "seeing" itself (and in today's philosophy of mind astonishingly little is said about the latter).'

claimThomas Nagel's expression 'what it is like to be' is widely accepted in the literature as capturing the essential nature of subjectivity, consciousness, qualia, and experience.
quoteJohn Searle remarked on the limitations of materialist theories of mind: "[the philosopher] encounters difficulties. It always seems that he is leaving something out… [and] underlying the technical objections is a much deeper objection… [that] can be put quite simply: The theory in question has left out the mind; it has left out some essential feature of the mind, such as consciousness or qualia or semantic content… [Thus] if we were to think of the philosophy of mind as a single individual we would say of that person that he is compulsive neurotic, and his neurosis takes the form of repeating the same pattern of behavior over and over."
