The claim

In brief
Seth’s Beast Machine TheoryThis theory posits that conscious experiences, including perceptions of the world and the self, are forms of brain-based perceptual prediction, metaphorically termed 'controlled hallucinations' . It roots the mechanism of consciousness in the fundamental biological imperative to regulate bodily physiology in order to stay alive .
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
Seth’s Beast Machine TheoryConsciousness is identified as forms of brain-based perceptual prediction, where phenomenological properties are explained by the computational aspects of different forms of prediction .
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
Seth’s Beast Machine TheoryLikelyAs a materialist theory focusing on computational and information-processing mechanisms (perceptual prediction) , AI systems that instantiate similar complex mechanisms should be capable of achieving consciousness .
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.
Does consciousness survive death?Differ
Seth’s Beast Machine TheoryNoConsciousness is a product of biological brains and complex, physically instantiated predictive machinery . The death of the brain leads to the irrevocable and permanent non-existence of personal consciousness .
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.
Could a mind be uploaded?Differ
Seth’s Beast Machine TheoryYesIf consciousness is entirely explicable by the computational processes of the brain , then, in principle, the first-person mental self could be duplicated and instantiated in a non-biological substrate, 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.
Does it give life meaning?Differ
Seth’s Beast Machine TheoryHumanistic onlyCategorized as a Materialism Theory, it implies no ultimate or cosmic meaning or purpose, although it supports human-created meaning and value derived from individual agency and experience .
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
Seth’s Beast Machine TheoryPhysicalism / Materialism (Justified by its classification under Materialism Theories and its reliance on biological and computational explanations) .
Spira’s Non-DualityOntological Idealism. The theory posits consciousness as the ultimate, singular, fundamental existent.
Mind and body
Seth’s Beast Machine TheoryConscious experiences are entirely brain-based and physically instantiated . The model supports a strong correlation or identity theory, where conscious properties arise from the physiological and computational architecture geared toward bodily regulation .
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
Seth’s Beast Machine TheoryEmergent
Spira’s Non-DualityPrimitive/Fundamental
Qualia
Seth’s Beast Machine TheoryThe phenomenological properties of conscious experiences are explained by the computational aspects of the different forms of perceptual prediction utilized by the brain .
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
Seth’s Beast Machine TheoryConsciousness is explained through predictive processing, where the brain generates a constant 'best guess' (prediction) of the causes of its sensory inputs . This mechanism is intrinsically tied to the regulation of bodily physiology .
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
Seth’s Beast Machine TheoryLocated in the biological brain, tied to the predictive machinery that regulates bodily physiology .
Spira’s Non-DualityUbiquitous/Cosmic. Consciousness is the underlying reality (single, infinite, indivisible) that pervades and underpins all existence.
What it does
Seth’s Beast Machine TheoryConsciousness has a functional role tied to survival . It facilitates the regulation of bodily physiology and allows the organism to model, predict, and simulate the causes of sensory inputs .
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
Seth’s Beast Machine TheoryEmpirically testable (Inferred, as the theory relies on concepts within the neurobiological and computational fields which emphasize development, testing, and comparison of theories) .
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
Seth’s Beast Machine TheoryTests involving predictive processing accounts of brain perception, cognition, and action (Justified: Specific named tests are not provided, but the theory is explicitly positioned within the predictive processing framework) .
Spira’s Non-DualityNot stated
Criticisms
Seth’s Beast Machine TheoryNot explicitly detailed in the source, but generally subject to the tension inherent in deflationary accounts 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.
