The claim
In brief
Integrated Information TheoryIIT is an original, radical model that proposes a definition for conscious experience and specifies which physical systems can possess it, starting from the phenomenology of consciousness (axioms). It translates these axioms into physical postulates based on intrinsic cause-effect power, featuring a mathematical measure Φ(Phi) to quantify a system's capacity for informational integration, which correlates with the degree of consciousness.
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
Integrated Information TheoryConsciousness is identified as a Φ-structure, a maximally reduced conceptual structure existing in 'qualia space'. An experience is identical to this conceptual structure, meaning its phenomenal properties correspond precisely to the physical properties of the cause-effect structure unfolded from the physical substrate of consciousness (PSC).
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
Can AI be conscious?Differ
Integrated Information TheoryNoKoch, a proponent, argues that consciousness is not computable. Digital computers have negligible integrated information (Φ(Phi)) due to hardware structure, meaning they can never be sentient, regardless of intelligence.
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.
Integrated Information TheoryUncertainIf phenomenal consciousness requires a radically new structure (like IIT's postulates), the potential permanence of these 'inscrutable things' cannot be rejected, leaving the possibility of survival open, even though IIT does not explicitly espouse life after 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.
Integrated Information TheoryNoIf consciousness is a fundamental property tied to real cause-effect power, a digital simulation (uploading) would only create a 'perfect zombie'—an entity that acts like the original but lacks subjective consciousness—because the simulation is virtual, lacking the required real cause-effect power.
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.
Integrated Information TheoryUncertainWhile the measurement and analysis of consciousness do not convey ultimate meaning, the speculative nature and novelty of the innumerable nth dimensional conceptual structures (conscious percepts) warrants suspending judgment on ultimate meaning/purpose/value.
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
Integrated Information TheoryIIT's fundamental ontology is the ontological primacy of phenomenal existence, based on an intrinsic powers view where what truly exists in physical terms are intrinsic entities capable of cause and effect. Koch notes that the theory insists consciousness must be incorporated into the basic description of reality at the rock-bottom level.
Advaita VedantaIdealism (Ontological Idealism/Nondualism).
Mind and body
Integrated Information TheoryIIT asserts an explanatory identity: an experience is identical to a Φ-structure. It contends that the conscious entity is the Φ-structure expressing its causal powers, not the neural substrate itself. This framework leaves no room for emergence or dualism.
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
Integrated Information TheoryConsciousness is defined by intrinsic existence and characterized as belonging to the basic description of reality. The theory rejects emergence.
Advaita VedantaPrimitive (Fundamental). Consciousness is defined as the singular fundamental existent.
Qualia
Integrated Information TheoryDistinct conscious experiences are conceptual structures in a 'qualia space'. The qualitative feel (phenomenal properties) corresponds one-to-one to the physical properties of the maximally irreducible cause-effect structure, which is also called a quale.
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
Integrated Information TheoryThe core principle is Integrated Information (Φ(Phi)), which quantifies the system's irreducibility. The Exclusion Postulate ensures that only the maximally irreducible cause-effect structure (the Φ-structure) exists intrinsically, defining the boundaries and grain of consciousness.
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
Integrated Information TheoryConsciousness is not limited to biological brains. IIT predicts the conscious structure resides in the posterior cortex (occipital, parietal, and temporal cortices). Systems with maximally irreducible intrinsic cause-effect power possess consciousness.
Advaita VedantaOmnipresent and pervasive throughout reality. Consciousness is universalized as Soul.
What it does
Integrated Information TheoryConsciousness is identified as unfolded intrinsic causal power, which is the ability to effect change. Only this intrinsic entity (the Φ-structure) can cause, supporting the claim that true free will exists for systems with high Φ(Phi).
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
Integrated Information TheoryIIT claims scientific testability, employing quantitative measurement. However, critics argue that the theory is not truly empirically tested, and its core predictions may be idiosyncratic.
Advaita VedantaSpeculative/Conceptual/Spiritual. The theory focuses on ultimate ontological reality, which is not typically subject to the scientific method.
Tests so far
Integrated Information TheoryCalculating Φ(Phi) for specific neural networks (e.g., visual cortex).,Monitoring brain activity as subjects slip into anesthesia.,Adversarial collaboration experiments testing predictions about sustained activity in the posterior cortex.
Advaita VedantaNot stated
Criticisms
Integrated Information TheoryThe theory faces criticism for anti-common sense predictions (imputing consciousness to simple objects). A public letter characterized IIT as 'pseudoscience'. Critics challenge that experiments test only idiosyncratic predictions and not the core metaphysical ideas. Chalmers noted the 'pseudoscience' label was disproportionate and caused vast collateral damage.
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.
