Christian Soul Theory and Tegmark’s State of Matter, 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, Tegmark’s State of Matter to Neutral Monism.
- Christian Soul Theory treats consciousness as fundamental; Tegmark’s State of Matter treats it as emergent.
- On AI consciousness, Christian Soul Theory says “Unlikely” and Tegmark’s State of Matter says “Yes”.
- On life after death, Christian Soul Theory says “Yes” and Tegmark’s State of Matter says “No”.
- On mind uploading, Christian Soul Theory says “No” and Tegmark’s State of Matter says “Likely”.
- On meaning and purpose, Christian Soul Theory says “Cosmic/Ultimate” and Tegmark’s State of Matter 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.
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
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.
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
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.
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.
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.
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.
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.
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.
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.
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
Christian Soul TheorySubstance Dualism. Reality consists of at least two ontological categories: physical (brain/body) and nonphysical (soul).
Tegmark’s State of MatterPhysicalism / Monism
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.
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
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.
Tegmark’s State of MatterEmergent
Qualia
Christian Soul TheoryQualia (qualitative feel) are phenomenal properties borne by the immaterial soul, which provides the single, unitary awareness of complex experiences.
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
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.
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
Christian Soul TheoryThe non-extended soul is associated with the body, being fully 'present' at each point within it.
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
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.
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
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.
Tegmark’s State of MatterEmpirically 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.
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
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.
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.
