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

The claim
In brief
Recurrent Processing TheoryLamme's Recurrent Processing Theory (RPT) posits that consciousness is both necessary and sufficient when reciprocal (recurrent) feedback connections occur among neural areas, particularly in sensory systems. This processing, which happens locally in sensory and post-sensory areas (Stage 3), generates phenomenal experience without requiring global broadcast 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
Recurrent Processing TheoryConsciousness is identified as a specific recurrent processing state holding within relevant neural circuitry, such as the visual system.
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
Recurrent Processing TheoryLikelyAs a Materialism Theory, AI consciousness must, in principle, be possible if the requisite pattern of recurrent processing could be artificially duplicated in a non-biological substrate.
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.
Recurrent Processing TheoryNoConsciousness is tied to physical brain activity and specific neural circuitry (recurrent processing states), suggesting cessation upon bodily 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.
Recurrent Processing TheoryYesSince consciousness is the recurrent processing state itself, a perfect duplication of that process onto a new medium (upload) would generate the first-person self, enabling virtual immortality.
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.
Recurrent Processing TheoryHumanistic onlyThe theory focuses on a purely physicalist, neurobiological explanation of phenomenal experience and does not support any ultimate cosmic meaning or purpose.
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
Recurrent Processing TheoryPhysicalism
Spira’s Non-DualityOntological Idealism. The theory posits consciousness as the ultimate, singular, fundamental existent.
Mind and body
Recurrent Processing TheoryIdentity/Reductionist approach, arguing that the notion of mind must move toward that of the brain, and consciousness is identical to a recurrent processing state in physical circuitry.
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
Recurrent Processing TheoryEmergent
Spira’s Non-DualityPrimitive/Fundamental
Qualia
Recurrent Processing TheoryQualia are generated when a certain recurrent processing state holds of the relevant visual circuitry, making the visual state conscious.
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
Recurrent Processing TheoryRecurrent processing (feedback connections) in sensory and post-sensory areas (Stage 3) is considered sufficient for consciousness.
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
Recurrent Processing TheoryLocalized in sensory and post-sensory areas, specifically recurrent activations in the 'back of the head'.
Spira’s Non-DualityUbiquitous/Cosmic. Consciousness is the underlying reality (single, infinite, indivisible) that pervades and underpins all existence.
What it does
Recurrent Processing TheoryConsciousness is the specific recurrent processing state itself. The underlying purpose is implied to move the understanding of mind toward the brain.
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
Recurrent Processing 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.

Criticisms
Recurrent Processing TheoryCritiques Global Workspace Theory (GWT) as being 'all about access but not about seeing'. Is itself criticized by Ned Block as a 'truncated form of the global workspace account'.
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.
