Scientific concepts, discoveries, nature phenomena

“Assemblage point” (Don Juan / Castaneda framework)

  • The assemblage point “collects” or organizes the world we perceive, without revealing reality as it is directly.
  • It has many possible positions.
  • An ordinary person keeps it fixed in one position, yielding a stable perceived world composed of:
    • Objects
    • Time
    • Causality
    • The self
  • Shifting the assemblage point does not mean physical travel; it means re-assembling another perceived world from the same raw material of reality.
  • The degree of shift corresponds to:
    • Minimal shift → figment of imagination
    • Significant shift → hallucination

ReMAP / “Rebus” predictive coding style model (neuroscience)

  • The brain is described as a prediction machine, not a passive receiver.
  • It continuously generates a pre-model of the world and compares it to incoming sensory signals.
  • These pre-models are prior beliefs (“priors”).
  • Hierarchy of priors:
    • Higher-level priors are more stable, associated with durable beliefs about:
      • Self
      • Causality
      • Nature
      • Reality
  • Normal perception is attributed to the influence of these high-level priors.

Psychedelics and changes in perception

  • Psychedelics temporarily weaken the accuracy/weight of high-level priors.
  • A key high-level prior is the “narrative self” / ego (belief in a specific personality, traits, and viewpoints).
  • With reduced ego/self-prior weighting:
    • Raw sensory information that is usually suppressed can flow upward
    • Limbic system data flow increases
    • Brain activity becomes more entropic (increased entropy)
    • The brain is less constrained by rigid habitual thinking
    • This allows another interpretation/assembly of reality from the same sensory inputs
  • This is framed as corresponding to Don Juan’s “shift of the assemblage point.”

List / methodology (outline)

Predictive-model perception mechanism (Rebus / predictive coding-style)

  • Generate a model of the world in advance.
  • Receive incoming sensory signals.
  • Compare signals against the model.
  • Use priors (especially high-level, stable ones) to shape perception.
  • Under psychedelics:
    • Weaken high-level priors
    • Allow more bottom-up sensory (including limbic) information
    • Increase entropy
    • Break habitual rigid patterns
    • Permit an alternate “assembly” of experience from the same sensory data

Researchers / sources featured

  • Don Juan (as presented through Carlos Castaneda’s reported conversations)
  • Robin Carhart-Harris (neuroscientist; subtitles spell variants like “Robin Carhartharis”)
  • Karl Friston (Imperial College London)
  • Imperial College London (institution mentioned via Friston / Carhart-Harris)
