The claim
In brief
Eliminative MaterialismPaul and Patricia Churchland hold that common-sense psychology, our everyday talk of beliefs, desires, and experiences, is a radically false theory that a completed neuroscience will displace rather than smoothly reduce. Consciousness as we ordinarily conceive it is a brain-generated picture shaped by evolution, and our self-understanding, introspection included, will be rebuilt in neuroscientific terms.
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.
What consciousness is
Eliminative MaterialismWhat we call consciousness, as folk psychology describes it, does not exist in that form. The real phenomena are neural processes, which only a mature neuroscience will describe correctly.
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.
Big questions
Eliminative MaterialismNo position
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.
Eliminative MaterialismNoSince the mind is the brain, nothing mental survives the brain’s death.
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.
Eliminative MaterialismNo position
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.
Eliminative MaterialismHumanistic onlyPatricia Churchland urges us to see ourselves as organisms in nature, understood by scientific methods, with no cosmic purpose.
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.
Nature of mind
Ontology
Eliminative MaterialismPhysicalism (eliminative)
Advaita VedantaIdealism (Ontological Idealism/Nondualism).
Mind and body
Eliminative MaterialismThe mind is the brain. Patricia Churchland calls her program a ‘unified theory of the mind-brain’ and treats claims that mind goes beyond brain as the residue of folk myths.
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.
Fundamental or emergent
Eliminative MaterialismNeither
Advaita VedantaPrimitive (Fundamental). Consciousness is defined as the singular fundamental existent.
Qualia
Eliminative MaterialismQualia as folk psychology and philosophers conceive them are expected to give way to neuroscientific description; the view treats consciousness as a kind of illusion generated by the brain.
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).
How it works
Mechanism
Eliminative MaterialismTheory displacement. Folk psychology will be replaced the way outdated scientific theories were, its principles and ontology discarded rather than mapped onto brain states.
Advaita VedantaNon-duality, where the infinite, ultimate consciousness limits or expresses itself in manifold, seemingly diverse forms to create individual subjects of experience.
Where it is
Eliminative MaterialismIn the brain.
Advaita VedantaOmnipresent and pervasive throughout reality. Consciousness is universalized as Soul.
What it does
Eliminative MaterialismBehavior is caused by neural processes; neuroscience is expected to explain it better than folk psychology 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.
Evidence and criticism
Testability
Eliminative MaterialismConceptually testable
Advaita VedantaSpeculative/Conceptual/Spiritual. The theory focuses on ultimate ontological reality, which is not typically subject to the scientific method.
Tests so far
Eliminative MaterialismThe view stakes its claim on the future course of neuroscience; whether folk categories survive in mature brain science is the long-run test.
Advaita VedantaNot stated
Criticisms
Eliminative MaterialismCritics say denying subjective experience defies both intuition and direct evidence; Galen Strawson calls the denial of experience ‘the strangest thing that has ever happened in the whole history of human thought’. There is also tension between Patricia Churchland’s talk of reduction to neurobiology and the eliminativist claim that folk psychology will be displaced rather than reduced.
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.
