The claim
In brief
BuddhismThis theory suggests that the sense of phenomenal consciousness or 'what-it-is-like-ness' is an instance of cognitive illusion, rejecting the existence of a permanent, inner 'self' or 'soul'. It posits that consciousness, like all phenomena, is ultimately empty of intrinsic nature, and is better understood as a network of relational processes.
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.
What consciousness is
BuddhismConsciousness (in the phenomenal sense) is identified as a cognitive illusion or conventional reality constituted by a network of processes/relations (Madhyamaka) or as an inner subjective substrate of representations (Yogācāra).
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).
Big questions
Can AI be conscious?Differ
BuddhismUncertainIf consciousness is fundamentally an illusion arising from a network of processes, it is unclear whether advanced computation (AI) can replicate the complex conventional reality or the specific non-self processes that generate this illusion, even though computation is not fundamentally ruled out.
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.
BuddhismYesThe eighth (store-house) consciousness persists after death, carrying karmic energy through cycles of reincarnation. However, survival often entails expansion back into cosmic consciousness, blurring or banishing individual first-person identity ('being sugar').
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.
BuddhismNot neededThe theory already provides a mechanism for persistence (the eighth consciousness) or transcendence (ninth consciousness), making artificial, digital duplication (virtual immortality) philosophically moot.
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.
BuddhismCosmic/UltimateThe ultimate goal is spiritual attainment (reaching the ninth consciousness or Buddha nature), which serves as the core source of energy and ultimate fulfillment, moving beyond merely humanistic purpose.
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.
Nature of mind
Ontology
BuddhismIdealism (specifically the Yogācāra school) or Deflationary Relationalism (specifically the Madhyamaka school), where all things are conventionally real but ultimately empty of intrinsic nature.
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.
Mind and body
BuddhismThe relationship is understood as interdependent and relational, lacking intrinsic self/substance. The illusion of a centralized mind or self is rejected.
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.
Fundamental or emergent
BuddhismConventional reality constituted by relations. It is neither a primitive substance nor an emergent property in the typical Western sense, as the phenomenal self it describes is fundamentally illusory.
Integrated Information TheoryConsciousness is defined by intrinsic existence and characterized as belonging to the basic description of reality. The theory rejects emergence.
Qualia
BuddhismQualia ('what-it-is-like-ness') are rejected as real, intrinsic properties and are instead viewed as illusory, dissolving away in favor of a network of underlying processes.
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.
How it works
Mechanism
BuddhismThe principle of emptiness (lack of intrinsic nature) applied to all phenomena, resulting in the realization that phenomenal consciousness is a cognitive illusion.
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.
Where it is
BuddhismNon-localized. Consciousness is often understood relationally. The ninth consciousness (Buddha nature) is the fundamental, purest core.
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.
What it does
BuddhismThe inward-directed seventh consciousness causes the concept of self, which is the source of deception. The eighth consciousness stores karmic energy and persists across death, thus enabling rebirth.
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).
Evidence and criticism
Testability
BuddhismLargely conceptual, based on internal philosophical coherence and phenomenological insights gained via meditative practices. Empirical studies sometimes correlate high-level meditation states (nirodha-samāpatti) with measurable brain changes (reduced synchronization).
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.
Tests so far
BuddhismStudy of high meditative states (nirodha-samāpatti) showing reduced overall brain synchronization.
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.
Criticisms
BuddhismWestern philosophers often find the core claim—that phenomenal consciousness is illusory—counter-intuitive and untenable. Internally, tension exists between the idealistic Yogācāra school and the relational Madhyamaka school.
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.
