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.
Searle’s Biological NaturalismBiological Naturalism posits that consciousness is a real, irreducible, subjective biological feature of the brain, entirely caused by lower-level neurobiological processes and realized as higher-level system features. This approach seeks to solve the mind-body problem by accepting the scientific worldview while acknowledging the first-person ontology of conscious experience.
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.
Searle’s Biological NaturalismConscious states are identified as real parts of the real world that are higher-level, system features of the brain, defined as states of awareness, sentience, or feeling that persist during wakefulness.

Big questions

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.
Searle’s Biological NaturalismConditionalSearle rejects consciousness via simulation (Chinese Room Argument) but argues that if the causally sufficient biological mechanism is known, an artificial machine that implements that same mechanism could be conscious, as consciousness does not strictly require biological neurons, only sufficient causal power.
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.
Searle’s Biological NaturalismNoConsciousness is entirely physical and solely the product of biological brains; therefore, death of the brain and body means irrevocable, permanent non-existence.
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.
Searle’s Biological NaturalismYesIf consciousness is entirely explainable by physical/biological states, then duplicating those states (and their causal relations) in a non-biological medium would, in principle, allow for the uploading and continuation of the first-person mental 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.
Searle’s Biological NaturalismHumanistic onlyAs a materialist theory, Biological Naturalism struggles to rationalize ultimate cosmic meaning or purpose, though humanistic meaning created by ourselves remains possible.

Nature of mind

Ontology
Advaita VedantaIdealism (Ontological Idealism/Nondualism).
Searle’s Biological NaturalismPhysicalism (Biological Naturalism). It holds that consciousness is part of nature as a subjective, qualitative biological property, rejecting attempts to 'naturalize' it by denying its subjective 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.
Searle’s Biological NaturalismConscious states are causally reduced to lower-level brain processes (causal reducibility), but are ontologically irreducible to these processes because consciousness has a subjective (first-person) ontology while its basis has an objective (third-person) ontology.
Fundamental or emergent
Advaita VedantaPrimitive (Fundamental). Consciousness is defined as the singular fundamental existent.
Searle’s Biological NaturalismEmergent
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).
Searle’s Biological NaturalismConscious states are inherently qualitative, in the sense that there is a distinct qualitative feel to being in any particular conscious state, and this qualitative feel is a real and irreducible part of the world.

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.
Searle’s Biological NaturalismThe principle is that all conscious states are reliably and universally caused by lower-level brain processes and realized as system features, functioning as a real biological machine.
Where it is
Advaita VedantaOmnipresent and pervasive throughout reality. Consciousness is universalized as Soul.
Searle’s Biological NaturalismLocalized in the biological brain, specifically realized in the brain as higher-level or system features.
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.
Searle’s Biological NaturalismConscious states function causally (causal efficacy) as real parts of the real world, providing a basis for intentional action and interaction with the environment.

Evidence and criticism

Testability
Advaita VedantaSpeculative/Conceptual/Spiritual. The theory focuses on ultimate ontological reality, which is not typically subject to the scientific method.
Searle’s Biological NaturalismEmpirically testable in principle, as the theory requires finding the exact causal details of how lower-level brain processes cause consciousness.
Tests so far
Advaita VedantaNot stated
Searle’s Biological NaturalismThe theory is generally supported by empirical evidence from neuroscience showing the link between consciousness and brain activity (e.g., brain impairment, brain stimulation).
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.
Searle’s Biological NaturalismCritics dispute the claim that the causal connection between brain states and consciousness is fully established. Tension exists in maintaining materialism while arguing consciousness is ontologically subjective and irreducible to objective physical processes.
