The claim
In brief
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.
Tegmark’s State of MatterTegmark proposes that consciousness can be understood as a specific state of matter, coined 'perceptronium,' which is defined by distinctive information-processing abilities. Starting from the premise that all existence is physical, the theory seeks principles that distinguish conscious, complex information processing from non-conscious processing.
What consciousness is
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.
Tegmark’s State of MatterConsciousness is identified as the subjective experience or 'feeling' that arises when information is being processed in certain complex ways, constituting the state of matter termed 'perceptronium'.
Big questions
Can AI be conscious?Differ
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.
Tegmark’s State of MatterYesThe theory is strictly physicalist ('It's all physics') and defines consciousness as a state of matter achievable through complex information processing. Therefore, artificial systems can achieve this state in principle.
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.
Tegmark’s State of MatterNoConsciousness is an emergent state of matter (perceptronium) of the physical brain. The irreversible death and dissolution of the physical substrate would entail the cessation of consciousness.
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.
Tegmark’s State of MatterLikelyIf consciousness is a specific informational state of matter defined by mathematical/physical principles, that state could potentially be perfectly duplicated or uploaded into a non-biological medium by advanced technology.
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.
Tegmark’s State of MatterHumanistic onlyThe foundation in physics and mathematical structure typically suggests no ultimate cosmic purpose, consistent with deflationary physicalist views. The theory does not explicitly propose cosmic teleology.
Nature of mind
Ontology
Spira’s Non-DualityOntological Idealism. The theory posits consciousness as the ultimate, singular, fundamental existent.
Tegmark’s State of MatterPhysicalism / Monism
Mind and body
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.
Tegmark’s State of MatterAn identity relationship is implied, where subjective experience (mind) is identified as a specific physical state (a state of matter/information processing).
Fundamental or emergent
Spira’s Non-DualityPrimitive/Fundamental
Tegmark’s State of MatterEmergent
Qualia
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.
Tegmark’s State of MatterQualia are implicitly the 'feeling' (subjective experience) associated with perceptronium's specific information processing configurations, formalized through four principles: information, integration, independence, and dynamics.
How it works
Mechanism
Spira’s Non-DualityNon-Duality, defined by the ultimate identity between the essence of the self and the ultimate reality (pure consciousness).
Tegmark’s State of MatterThe definition of perceptronium via the application of four distinct principles (information, integration, independence, and dynamics) to information processing in physical systems.
Where it is
Spira’s Non-DualityUbiquitous/Cosmic. Consciousness is the underlying reality (single, infinite, indivisible) that pervades and underpins all existence.
Tegmark’s State of MatterLocalized to physical systems (e.g., neural networks or arbitrary quantum systems) that achieve the specific information-processing criteria defining perceptronium.
What it does
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.
Tegmark’s State of MatterConsciousness is crucial for information assessment and is viewed as functionally important for critical needs like caring for comatose patients or communicating with advanced AI. Causation is strictly physical.
Evidence and criticism
Testability
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.
Tegmark’s State of MatterEmpirically testable
Tests so far
Spira’s Non-DualityNot stated
Tegmark’s State of MatterThe generalization of Integrated Information Theory implies relevance to IIT's measurement function (quantifying degrees of consciousness). The theory is intended to address concrete problems like assessing comatose patients and advanced AI.
Criticisms
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.
Tegmark’s State of MatterAs a generalization of IIT, it inherits existing critiques, such as the difficulty in explaining subjective feeling purely through physical and informational principles.
