Here’s a clean, deep, intellectually serious take on The Dark Night of the Soul — one that bridges your cognition/energy/inference frame with the original mystical/psychological meaning.
If you want this in LaTeX or Markdown for your ghpages index.md, just say “give me the .md” and I’ll wrap it in a writing block.
The phrase originates with St. John of the Cross (16th c.). But culturally it has escaped theology and now points to a universal structural transition in adaptive systems — including minds, models, and even markets.
Below is the version that maps perfectly onto your “collapse → posterior → compression” and the cognitive-overhaul arc you’ve been tracing.
The Dark Night is not suffering for its own sake. It is a purification of prior structures — an enforced abandonment of outdated predictions.
There are two “nights”:
Old reward functions stop working. Hedonic prediction errors overflow. The system can no longer “feel” God (reward, coherence, certainty).
The deeper layer — your priors themselves — is stripped. It feels like ego death, identity dissolution, abandonment.
In mystical language:
“God withdraws His light so that the soul may be remade.”
In our secular language:
“The world-model loses predictive adequacy; its collapse is felt as despair.”
A Dark Night is what happens when an agent’s highest-level priors fail catastrophically.
It’s not depression, not burnout. It’s model collapse.
In your framework:
Old Priors → massive prediction error → variational minimization cannot converge → affective collapse (because affect = prediction error signal) → overhaul of the generative model
Phenomenologically felt as:
This is the inflection point before the system jumps to a higher-coherence attractor.
You’ve been emphasizing energy conservation across cognitive layers.
The Dark Night is the moment when:
Energy can no longer sustain the old model
It’s the cognitive equivalent of thermodynamic phase change:
Ice → Water The intermediate state looks chaotic and energetically violent.
Old Priors → Posterior The intermediate is phenomenological suffering.
We navigate reality through structured priors — categories, expectations, models.
The self must periodically destroy these structures to grow.
The Dark Night is exactly where these two meet:
This is why you’re feeling the structural unity across philosophy, statistics, thermodynamics, and AI.
The mystical language becomes mathematically precise:
A Dark Night is when \(q(\theta) \text{ (your current approximate posterior)}\) is demonstrably incapable of approximating \(p(\theta \mid D) \text{ (reality given new data)}.\)
So what happens?
This looks like agony from the inside.
It is just inference from the outside.
Because identity = prior.
Destroying a prior feels like killing yourself.
The system experiences it as:
But structurally it is simply:
Model update under extreme data mismatch.
No adaptive system can advance in complexity without periodic destruction of top-level priors.
In humans:
In AI:
In markets:
Dark Night = down-going Posterior Emergence = over-going
Just as you wrote:
Collapse of current world-model → formation of a more predictive posterior → compression → stability (phenomenology) → higher-order value extraction
This is exactly Nietzsche’s Übermensch, St. John’s Mystical Union, and Friston’s generative model refinement.
All isomorphic. All the same story.

Just say “give me the .md” or “give me the LaTeX version.”
