Christian Soul Theory vs Attention Schema Theory
Christian Soul Theory and Attention Schema Theory, compared field by field from their entries in the Atlas.
At a glance
- Christian Soul Theory belongs to the Dualism family in Kuhn's Landscape of Consciousness, Attention Schema Theory to Materialism.
- Christian Soul Theory treats consciousness as fundamental; Attention Schema Theory treats it as emergent.
- On AI consciousness, Christian Soul Theory says “Unlikely” and Attention Schema Theory says “Likely”.
- On life after death, Christian Soul Theory says “Yes” and Attention Schema Theory says “No”.
- On mind uploading, Christian Soul Theory says “No” and Attention Schema Theory says “Possible”.
- On meaning and purpose, Christian Soul Theory says “Cosmic/Ultimate” and Attention Schema Theory says “Humanistic only”.

The claim
In brief
Christian Soul TheoryThis theory posits that the human person is composed of two fundamentally distinct substances: a wholly immaterial, substantial soul (the self) and a physical body or brain. The soul is the locus of consciousness, provides personal identity, and interacts with the body in a cause-and-effect manner.
Attention Schema TheoryThis theory posits that consciousness arises when the brain constructs a quick, simplified, internal model—an attention schema—of its own process of attention. The brain mistakenly interprets and reports this internal representation as a subjective, non-physical essence or a 'self-caricature,' even though it is fundamentally a computational product.
What consciousness is
Christian Soul TheoryConsciousness and the mind are grounded in the substantial, unified, wholly immaterial soul, which is the entity that has experiences and grounds personal identity.
Attention Schema TheoryConsciousness is identified as the brain’s internal representation or simplified model of its own mechanism of attention (the attention schema), which is a specific example of higher-order thought.
Big questions
Can AI be conscious?Differ
Christian Soul TheoryUnlikelyIf consciousness requires a radically separate, nonphysical substance (soul) that is divinely created or allocated, non-biological intelligences could not generate this necessary component, making AI consciousness impossible.
Attention Schema TheoryLikelySince consciousness is defined as a computational process (the creation of an attention schema), in principle, artificial systems that implement the necessary computational architecture could become conscious. Furthermore, observers will inevitably make the social attribution of consciousness to sufficiently complex AI systems that act like they are conscious.
Christian Soul TheoryYesThe soul is the ‘real you,’ existing independently of the body and providing the clearest mechanism for the persistence of individual consciousness post-mortem, fulfilling the core tenet of Abrahamic religions.
Attention Schema TheoryNoAs a Materialist/Neurobiological theory, consciousness is tied to the physical substrate (the biological, information-processing machine), precluding survival beyond the decay of the body.
Christian Soul TheoryNoUploading neural patterns and pathways would only duplicate the physical basis of consciousness. Since the necessary nonphysical substance (the soul) would be absent from the duplicate, first-person mental self-preservation would be impossible.
Attention Schema TheoryPossibleIf the consciousness is realized as a computational structure (the attention schema), and if this structure and the relevant information processing systems can be accurately uploaded to a non-biological medium, virtual immortality is theoretically possible.
Christian Soul TheoryCosmic/UltimateAs a theological theory, it provides ultimate meaning, purpose, and value tied to divine creation, destiny, and the spiritual nature of human existence.
Attention Schema TheoryHumanistic onlyConsciousness provides an adaptive, evolutionary purpose (monitoring and regulating attention for action control), but does not imply any ultimate or cosmic meaning, consistent with Materialism.
Nature of mind
Ontology
Christian Soul TheorySubstance Dualism. Reality consists of at least two ontological categories: physical (brain/body) and nonphysical (soul).
Attention Schema TheoryPhysicalism
Mind and body
Christian Soul TheoryInteractionist: The immaterial soul relates to the physical body/brain in an informing and cause-effect way, meaning physical states cause phenomenal states, and phenomenal states cause physical states.
Attention Schema TheoryConsciousness is the report generated by a biological, information processing machine (the brain) through the assessment of its internal data, meaning mental states are computational and wholly physical.
Fundamental or emergent
Christian Soul TheoryPrimitive. The soul is a substantial, nonphysical substance, often held to be created and allocated by God (Creationism) rather than arising from material processes.
Attention Schema TheoryEmergent
Qualia
Christian Soul TheoryQualia (qualitative feel) are phenomenal properties borne by the immaterial soul, which provides the single, unitary awareness of complex experiences.
Attention Schema TheoryConsciousness is described as a 'self-caricature' or an illusory report of a non-physical essence, suggesting a deflationary or illusionist account of qualia, akin to Daniel Dennett’s view.
How it works
Mechanism
Christian Soul TheoryInteractionism, which requires that the physical world is not causally closed, allowing the nonphysical soul to exert causal power over the physical brain and vice versa.
Attention Schema TheoryThe construction and maintenance of a simplified internal model (the attention schema) of the process of attention, rooted in principles from control engineering.
Where it is
Christian Soul TheoryThe non-extended soul is associated with the body, being fully 'present' at each point within it.
Attention Schema TheoryLocated within the biological, information-processing system of the brain.
What it does
Christian Soul TheoryThe soul's main functional role is providing causal efficacy for mental states (especially in relation to libertarian free will) and grounding personal identity. It also gives form to and animates the body.
Attention Schema TheoryThe functional role of the attention schema is to monitor and regulate the brain's attention in order to control actions in the world. The resulting capacity allows the system to claim consciousness.
Evidence and criticism
Testability
Christian Soul TheorySpeculative/Philosophical. Direct empirical testing is impossible due to the soul’s nonphysical nature. It is argued that empirical evidence for survival beyond death (like NDEs/OBEs) would instantaneously falsify materialism and support dualism.
Attention Schema TheoryEmpirically testable
Tests so far
Christian Soul TheoryReported observations such as near-death experiences (NDEs) and out-of-body experiences (OBEs) are cited by adherents as phenomena requiring a nonphysical explanation, which the soul provides.
Attention Schema TheoryNot stated
Criticisms
Christian Soul TheoryThe primary tension is the problem of mental causation (how an immaterial soul can causally interact with the physical body/brain) and the conflict with the widely accepted scientific principle of the causal closure of the physical world. Critics often attribute persistence in this view to 'folk myths' or persistent traditions.
Attention Schema TheoryThe theory explains how a system can *claim* consciousness but faces the general limitation, shared by similar functionalist models, of conclusively proving or explaining the actual subjective feel (the 'anybody home' problem) which remains eternally uncertain, even by the proponent's admission.
