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.
Dennett’s IllusionismDaniel Dennett argues that qualia, conceived as intrinsic, ineffable, private, and immediately known properties of experience, do not exist; they are philosophers’ inventions. Experience is real, but it is not what it seems from the inside: the brain’s unconscious processes produce a benign ‘user illusion’, and there is nothing to consciousness beyond the functions and dispositions involved.
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).
Dennett’s IllusionismConsciousness is the functional activity of the brain, which presents itself to us as a user illusion. ‘There are no qualia.’

Big questions

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.
Dennett’s IllusionismPossibleSince consciousness is nothing beyond functions and dispositions, a machine with the right functional organization could have it; Dennett does not take this up here.
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').
Dennett’s IllusionismNoSince consciousness is a product of the brain’s processes, it ends when they end.
BuddhismNot neededThe theory already provides a mechanism for persistence (the eighth consciousness) or transcendence (ninth consciousness), making artificial, digital duplication (virtual immortality) philosophically moot.
Dennett’s IllusionismNo position
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.
Dennett’s IllusionismHumanistic onlyDennett’s materialism, and his place among the New Atheists, leave no room for cosmic purpose.

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.
Dennett’s IllusionismPhysicalism (illusionist)
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.
Dennett’s IllusionismConsciousness is wholly a product of the brain’s unconscious processes. Dennett rejects any inner, non-physical domain of felt properties.
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.
Dennett’s IllusionismEmergent
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.
Dennett’s IllusionismThere are no qualia in the traditional sense. Dennett calls the supposed intrinsic, ineffable, private properties ‘nothing but philosophers’ inventions’.

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.
Dennett’s IllusionismThe user illusion. As a computer’s desktop icons stand in for complex underlying processes, the brain presents itself to us in a simplified form we mistake for an inner world of qualities.
Where it is
BuddhismNon-localized. Consciousness is often understood relationally. The ninth consciousness (Buddha nature) is the fundamental, purest core.
Dennett’s IllusionismIn the brain’s unconscious processes, with no inner theater.
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.
Dennett’s IllusionismThe user illusion is benign: it lets us manage ourselves without access to the brain’s underlying complexity.

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).
Dennett’s IllusionismConceptually testable
Tests so far
BuddhismStudy of high meditative states (nirodha-samāpatti) showing reduced overall brain synchronization.
Dennett’s IllusionismNot stated
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.
Dennett’s IllusionismDennett is often read as denying that experience exists, and critics reply that an illusion of experience would itself be an experience. Dennett resisted the eliminativist label, though many philosophers apply it to his rejection of qualia.
