The claim
In brief
Advaita VedantaThis theory posits that consciousness is the singular, nondual fundamental reality (Brahman) that constitutes all existence. Individual human consciousness is ultimately non-different from this pervasive Cosmic Consciousness, which generates first-person inner experiences (qualia). The physical world, including the body-mind complex, is considered derivative or illusionary.
Sam HarrisThis perspective, offered as a challenge rather than a prescriptive theory, frames consciousness as an unbridgeable mystery that cannot be solved by purely physical means. Harris argues that physical descriptions are 'mute' regarding subjective experience; the only thing attesting to sentience is consciousness itself, creating a fundamental explanatory gap. He remains pessimistic that science can dispel this mystery.
What consciousness is
Advaita VedantaConsciousness (Brahman/Cit) is the one nondual reality. Individual consciousness is identified as the all-pervading Cosmic Consciousness expressing itself through the body-mind complex.
Sam HarrisConsciousness is identified as subjectivity or sentience, which is fundamentally mysterious and unexplainable by purely physical processes.
Big questions
Can AI be conscious?Differ
Advaita VedantaConditionalIf consciousness is fundamental and pervasive throughout reality, then artificial systems could potentially instantiate or participate in cosmic consciousness, provided they meet the structural/complexity requirements for manifestation, though some idealists reject conscious AI based on current computer models.
Sam HarrisNoIf consciousness is irreducible subjectivity missing from physical descriptions, then advanced computation (AI, which is purely physical complexity) will fail to generate genuine sentience.
Advaita VedantaYesSurvival is a fundamental doctrine in Indian traditions (e.g., reincarnation). However, survival often means the eventual loss of current first-person awareness as consciousness is re-absorbed into the ultimate Cosmic Consciousness.
Sam HarrisNoAs a naturalist, Harris implicitly aligns with the view that consciousness is tied to the physical organism, meaning its termination results in permanent non-existence, despite the mystery of its nature while alive.
Advaita VedantaNot neededIf consciousness is already fundamental and eternal (Idealism), traditional concepts of survival or eternal life are already theoretically available, making technological virtual immortality moot.
Sam HarrisNoIf consciousness cannot be explained by purely physical processes, then duplication or uploading of the physical substrate will fail to capture or recreate the essential subjective self.
Advaita VedantaCosmic/UltimateBy positing consciousness as the ground of all being and ultimate reality, the theory inherently provides cosmic meaning and purpose. Evolutionary Idealist views also see the evolution of consciousness as a primary feature of world meaning.
Sam HarrisHumanistic onlyThe mystery does not imply cosmic purpose, but Harris advocates finding personal truths through introspection, aligning with self-discovered (naturalized) spirituality and meaning.
Nature of mind
Ontology
Advaita VedantaIdealism (Ontological Idealism/Nondualism).
Sam HarrisSkeptical/Mysterianism (Justified: The view asserts the philosophical intractability and unbridgeable nature of the mind-body problem, aligning with core tenets of mysterianism, though without adopting a specific alternative ontology.)
Mind and body
Advaita VedantaThe mind and physical world are derivative or illusionary manifestations of the fundamental consciousness. The consciousness shines through the body-mind complex, but is not the body or mind itself.
Sam HarrisUnbridgeable Gap / Non-reductive Correlation (Justified: Harris asserts that while physical processes correlate with consciousness, no analysis of these processes can logically yield a picture of consciousness, leaving an unbridgeable gap.)
Fundamental or emergent
Advaita VedantaPrimitive (Fundamental). Consciousness is defined as the singular fundamental existent.
Sam HarrisMystery (Justified: Harris declines to fully endorse emergence, stating that while consciousness may be the lawful product of unconscious processing, he does not find that sentence meaningful in explaining sentience.)
Qualia
Advaita VedantaQualia (first-person inner experiences) are generated by the all-pervading cosmic consciousness. Experience is categorized into intransitive awareness (pure consciousness, devoid of content) and transitive awareness (phenomenal consciousness, which is a reflection or semblance of real consciousness).
Sam HarrisQualia (what it is 'like something' to be) are the phenomenon that physical events are 'mute' about, thus creating the unbridgeable mystery.
How it works
Mechanism
Advaita VedantaNon-duality, where the infinite, ultimate consciousness limits or expresses itself in manifold, seemingly diverse forms to create individual subjects of experience.
Sam HarrisNone (Justified: The core premise is the failure of all current and foreseeable physical/mechanistic principles to explain subjectivity.)
Where it is
Advaita VedantaOmnipresent and pervasive throughout reality. Consciousness is universalized as Soul.
Sam HarrisUnknown/Mysterious (Justified: While consciousness correlates with the brain, the theory explicitly rejects confining the explanation of consciousness to physical location or distribution because the physical world yields no evidence of consciousness.)
What it does
Advaita VedantaConsciousness is the ultimate source and ground of all being. It governs causation and creates energy and matter. The existence of consciousness is its own explanation, needing no outside cause.
Sam HarrisUnknown/Irreducible (Justified: Causal power is not explained by unconscious complexity. The presence of sentience is an ultimate mystery rather than a functional adaptation that can be described reductively.)
Evidence and criticism
Testability
Advaita VedantaSpeculative/Conceptual/Spiritual. The theory focuses on ultimate ontological reality, which is not typically subject to the scientific method.
Sam HarrisConceptually Untestable (Justified: If the gap is unbridgeable, as Harris claims, the mystery cannot be dispelled by empirical science as currently practiced.)
Tests so far
Advaita VedantaNot stated
Sam HarrisNone (Justified: The framework is a diagnosis of science's failure to address the hard problem and does not propose empirical tests for the mystery itself.)
Criticisms
Advaita VedantaCriticized for being anti-physicalist and relying on religious tradition. It faces the challenge of explaining how the physical world emerges or is derived from fundamental consciousness, an odd idea alien to common life experiences. It is contrasted with other Indian schools like GV Vedanta, which has differences regarding the ontological reality of matter and individual selves.
Sam HarrisIt functions primarily as a critique against reductionism and scientific optimism regarding consciousness, classifying the issue as an ultimate mystery, which reductionists reject as pessimism (mysterianism).
