Global Workspace Theory vs Spira’s Non-Duality
Baars’s and Dehaene’s Global Workspace Theory and Spira’s Non-Duality, compared field by field from their entries in the Atlas.
At a glance
- Global Workspace Theory belongs to the Materialism family in Kuhn's Landscape of Consciousness, Spira’s Non-Duality to Idealism.
- Global Workspace Theory treats consciousness as emergent; Spira’s Non-Duality treats it as fundamental.
- On AI consciousness, Global Workspace Theory says “Yes” and Spira’s Non-Duality says “No”.
- On life after death, Global Workspace Theory says “No” and Spira’s Non-Duality says “Yes”.
- On mind uploading, Global Workspace Theory says “Yes” and Spira’s Non-Duality says “Not needed”.
- On meaning and purpose, Global Workspace Theory says “Humanistic only” and Spira’s Non-Duality says “Cosmic/Ultimate”.

The claim
In brief
Global Workspace TheoryThis theory posits that conscious awareness is constituted by specific multi-sensory, multi-cognitive information that achieves brain-wide presence and broad accessibility. It conceptualizes consciousness as an inner 'theater' where this information is globally broadcast, reconciling the limited capacity of momentary conscious content with vast long-term memory access.
Spira’s Non-DualityThis theory proposes that ultimate reality is a single, infinite, and indivisible pure consciousness (non-duality), from which all objects and individual selves derive their apparently independent existence. It asserts that our essential nature, which is this pure consciousness, transcends the limits and destiny of the physical body and mind.
What consciousness is
Global Workspace TheoryConsciousness is identified as the instantaneous global availability and broad accessibility of specific, integrated information across numerous specialized modular systems in the brain.
Spira’s Non-DualityConsciousness is identified as the single, infinite, and indivisible reality (pure consciousness) from which all apparent objects and individual selves derive their existence.
Big questions
Can AI be conscious?Differ
Global Workspace TheoryYesSince the theory defines consciousness in terms of information-processing computations and architectures, and proponents suggest novel machine architectures could be based on these computations, AI consciousness is possible in principle.
Spira’s Non-DualityNoIf consciousness is the singular, non-material ultimate reality, artificial systems (being derived/material objects) cannot achieve true consciousness, only a functional imitation or borrowing of existence from the ultimate reality.
Global Workspace TheoryNoConsciousness is understood as being entirely dependent on specific, complex biological brain processes, which cease upon biological death.
Spira’s Non-DualityYesThe theory explicitly states that our essential nature, being pure consciousness, does not share the limits or destiny of the body and mind, implying survival or continuity beyond biological dissolution.
Global Workspace TheoryYesIf consciousness is wholly explained by the computational organization and information flow of the brain, a perfect duplication or uploading of these mechanisms into a non-biological substrate should preserve the first-person mental self.
Spira’s Non-DualityNot neededSince the essential self is fundamentally non-physical, infinite consciousness, digital duplication of the body/mind is unnecessary for the persistence of the essential self.
Global Workspace TheoryHumanistic onlyAs a Materialist/Neurobiological theory, it does not mandate ultimate cosmic meaning or purpose, but consciousness provides essential functions (like memory reconciliation and integrated awareness) that underpin human agency and self-created value.
Spira’s Non-DualityCosmic/UltimateConsciousness is the foundation of reality ('the nature of reality') and understanding this non-dual essence is the key to achieving ultimate peace and happiness, providing inherent cosmic purpose.
Nature of mind
Ontology
Global Workspace TheoryPhysicalism
Spira’s Non-DualityOntological Idealism. The theory posits consciousness as the ultimate, singular, fundamental existent.
Mind and body
Global Workspace TheoryIdentity/Correlation. The mind (conscious awareness) is identified as, or strongly correlates with, the specific, biologically realized processes of global information broadcasting in the brain.
Spira’s Non-DualityThe essential nature of the self (consciousness) is held to be independent of the physical body and mind. Physical existence, and all experience, is mediated through the mind, which is derived from the fundamental consciousness.
Fundamental or emergent
Global Workspace TheoryEmergent
Spira’s Non-DualityPrimitive/Fundamental
Qualia
Global Workspace TheoryPhenomenal experience (qualia) is accounted for by proposing a strictly biological mechanism for conscious awareness. Qualia correspond to the content of the integrated, reportable multi-sensory information that is broadly accessible within the global workspace.
Spira’s Non-DualityQualia (multiplicity and diversity of experience) are seen as manifestations or derivations of the underlying singular pure consciousness, borrowing their apparent independent existence from it.
How it works
Mechanism
Global Workspace TheoryGlobal broadcasting and accessibility of information, allowing a single coherent content to be made available to many specialized, unconscious modules simultaneously.
Spira’s Non-DualityNon-Duality, defined by the ultimate identity between the essence of the self and the ultimate reality (pure consciousness).
Where it is
Global Workspace TheoryBrain-wide, encompassing widespread areas, particularly associated with frontal and parietal regions (often characterized as a 'front of the head' theory in contrast to 'back of the head' theories like IIT).
Spira’s Non-DualityUbiquitous/Cosmic. Consciousness is the underlying reality (single, infinite, indivisible) that pervades and underpins all existence.
What it does
Global Workspace TheoryGlobal broadcasting constitutes consciousness. Functionally, it allows for flexible control and reconciliation between limited momentary conscious content and long-term memory resources.
Spira’s Non-DualityConsciousness functions as the ontological source of all existence. Achieving the recognition of this pure consciousness is tied to the ultimate goal of finding lasting peace and happiness.
Evidence and criticism
Testability
Global Workspace TheoryEmpirically testable
Spira’s Non-DualitySpeculative/Conceptual. The theory relies on philosophical and spiritual recognition of ultimate reality rather than empirical methods based on third-person observation.
Tests so far
Global Workspace TheoryNeuroimaging and computer modeling studies used to investigate its claims. It is implicitly subject to the 'neurogeographic' debate contrasting 'front of the head' theories with posterior theories.
Spira’s Non-DualityNot stated
Criticisms
Global Workspace TheoryCriticized for focusing on 'access' rather than genuine phenomenal experience, exemplified by the critique that the theory is 'all about access but not about seeing'. It faces tension regarding whether global broadcasting is necessary or merely a consequence of consciousness.
Spira’s Non-DualityLike other Idealist theories, it faces the challenge of explaining precisely how the fundamental, non-material consciousness generates or interacts with the apparent physical world and matter.
