The last rally

 


Look what I found. 

This is a kind of follow up to the robot essay "Better than panpsychism". Rupert Sheldrake and Mark Vernon discusses the strange phenomenon of terminal lucidity in humans *and animals*. It seems dogs and cats also experience "the last rally". The commentary section is worth reading. 

At the end of the video, Sheldrake and Vernon try to wrap everything up by discussing the resurrection of Christ from a somewhat heterodox perspective. 

Actually quite interesting. Thank you, guys, you may have saved my faith!

Better than panpsychism? (Part 2)

 


Part 2 of the bonus midnight essay...

Can you tell me more about how reduced brain activity leads to richer (!) experiences?

Yes! The idea that reduced brain activity can lead to richer or more intense experiences is one of the most surprising and intriguing findings in recent neuroscience—and it has profound implications for theories of consciousness, including cosmopsychism and the “brain-as-filter” model.

Let’s explore how this works, and why it matters.


🧠 The Standard View: Brain Produces Consciousness

Traditionally, neuroscience assumes:

  • More brain activity = more consciousness

  • Consciousness is a byproduct or emergent effect of complex information processing in the brain (especially in the cortex).

  • So, intense or vivid experiences should require more neural firing, not less.

But some empirical findings challenge this.


🔬 The Counterintuitive Finding: Less Activity, More Experience

🌈 1. Psychedelics and Brain Entropy

Study Example: Carhart-Harris et al. (2012–2016)

  • Participants took psilocybinLSD, or DMT.

  • fMRI and MEG scans showed:

    • Decreased activity in key brain regions, especially:

      • Default Mode Network (DMN): associated with ego, self-reflection

      • Thalamus: a relay/filter station for sensory input

But Subjective Reports Said:

“I experienced infinite space, timelessness, union with the universe, profound love and understanding…”

So: richer experience came with reduced neural activity.


🧘 2. Meditative and Mystical States

  • Deep meditation and advanced nondual awareness (as in Zen, Vedanta, Dzogchen) show quieted or synchronized brain states.

  • EEGs often show low-frequency oscillations (alpha/theta) and reduced cortical noise.

  • Yet practitioners report:

    “Boundless awareness, deep clarity, unity with all existence.”

This again supports the idea that less internal noise → more clarity or access to deeper forms of experience.


⚰️ 3. Near-Death Experiences (NDEs)

  • In cardiac arrest or clinical death, the brain often loses activity very quickly.

  • But some NDE reports describe:

    “Hyper-real clarity, panoramic life reviews, feeling of oneness, immense peace…”

There’s debate over whether these happen during or after the brain shuts down—but they challenge the assumption that full consciousness requires normal brain function.


🧠🪞 The Brain-as-Filter Hypothesis

These findings support the old but radical idea (endorsed by cosmopsychism and thinkers like William James, Aldous Huxley, and Henri Bergson):

The brain does not create consciousness—it filters, restricts, or shapes it.

Analogy: Light through a Prism

  • Consciousness is like white light.

  • The brain acts like a prism: it breaks the light into limited bands, filtering what we perceive.

  • When the prism is altered (by psychedelics, meditation, or NDEs), we see more of the light.

This fits well with cosmopsychism, where:

  • The cosmic consciousness is already present.

  • The brain narrows and localizes that vast field into a functional self-model.

  • Shut off or suppress that filter—and more of the original field "shines through".


🧬 Neuroscience Models That Support This

1. REBUS Model (Relaxed Beliefs Under Psychedelics)

  • Developed by Robin Carhart-Harris.

  • Suggests psychedelics “loosen” top-down control by the DMN and allow bottom-up sensory and emotional flow to rise.

  • This increases entropy in brain activity (more variability, more openness).

2. Entropic Brain Theory

  • Consciousness is linked to complexity and variability of brain states.

  • Psychedelics increase entropy, while anesthesia and coma reduce it.

So organized suppression, not chaos, may be what normally creates the narrow bandwidth of "ordinary waking consciousness."


🔚 Summary: When Less Is More

Brain ConditionNeural ActivityReported Experience
PsychedelicsDecreased DMN activityEgo dissolution, cosmic unity
Deep meditationReduced cortical chatterStillness, pure awareness, nonduality
Near-death experiencesSharply reduced activityHyper-real visions, timelessness

All of this challenges the “brain-as-generator” model and points toward:

  • Consciousness as primary, not secondary.

  • The brain as a tuner or limiter, not a producer.


Would you like to explore:

  • Historical roots of the brain-as-filter idea?

  • How this supports cosmopsychism vs. panpsychism?

  • Or criticisms of the neuroscience interpretations?

Let’s go wherever your curiosity leads.

What about "terminal lucidity"?

Terminal lucidity is a fascinating—and often deeply moving—phenomenon that poses real challenges to mainstream neuroscience and adds weight to alternative theories of consciousness, including cosmopsychism and the brain-as-filter hypothesis.

Let’s break it down:


🧠 What Is Terminal Lucidity?

Terminal lucidity refers to the sudden, unexpected return of mental clarity in people who are:

  • In the final stages of life

  • Often suffering from severe dementiabrain tumorsschizophrenia, or delirium

  • And sometimes non-verbal or unresponsive for weeks, months, or years

Then, just before death—sometimes hours, sometimes minutes—they:

  • Speak coherently

  • Recognize family

  • Express love, forgiveness, even insights

  • Show uncharacteristic lucidity and personality

And then… they die.


🧪 Notable Features of Terminal Lucidity

FeatureDescription
Sudden return of cognitionPerson speaks, remembers, or reasons clearly
Happens before deathUsually within hours or a day
Not explained by medicationNot due to stimulants or sedatives wearing off
Seen across conditionsDocumented in Alzheimer’s, schizophrenia, coma
Cross-cultural reportsFound worldwide, from ancient to modern times

🧩 Why It’s a Problem for Mainstream Neuroscience

❗ Severe brain damage + high cognition = paradox

People in advanced Alzheimer’s, for instance, can show:

  • Severe cortical atrophy

  • Virtually no short-term memory

  • Little language ability

According to reductionist brain models, these abilities should be permanently lost—yet in terminal lucidity, they briefly return.

How does a dying, heavily damaged brain suddenly "reboot" complex cognition?

There’s no accepted neurophysiological mechanism to explain this.


🧘 Interpretations That Fit the Phenomenon

1. 🔎 Brain-as-Filter Hypothesis

  • Consciousness is always present (e.g., cosmic or transpersonal)

  • The brain limits access to that consciousness

  • As the brain deteriorates or shuts down, the filter breaks, allowing “wider” consciousness to shine through

So terminal lucidity isn't paradoxical—it's what happens when the filter fades away.

This fits well with:

  • Cosmopsychism (consciousness as cosmic field)

  • Spiritual traditions (e.g., Vedānta, where the Self is eternal)

  • Some parapsychological models (survivalist theories of consciousness)


2. 🧬 Quantum or Field-Based Theories of Mind

Some researchers speculate that:

  • Consciousness may not reside in the brain, but interact with it non-locally

  • As the brain "dies", it releases the constraints that limited consciousness

This ties into quantum mind theories and proposals like:

  • Orch-OR (Penrose & Hameroff)

  • Field consciousness models

  • Holographic brain theories

These are controversial and not widely accepted, but terminal lucidity gives such models an empirical puzzle to address.


📚 Documented Cases

Some well-known examples (from case reports and hospice staff accounts):

  • An elderly woman with Alzheimer’s for 10 years, unable to speak, suddenly recognizes her daughter, has a clear conversation, then dies that night.

  • A man with schizophrenia and catatonia for years suddenly becomes lucid, apologizes to family, and passes peacefully.

  • A patient in a non-responsive coma suddenly opens his eyes, speaks a few sentences with clarity, then flatlines.

These are not miracles—they are documented patterns, though under-studied.


🧪 Why It's Hard to Study

  • Terminal lucidity is often unexpected and brief

  • Happens in palliative or hospice settings, with no real-time brain scans

  • Ethical and logistical issues limit controlled observation

  • Medical science still lacks models to predict or explain it

But it's increasingly being systematically reported, especially by hospice workers and end-of-life researchers (e.g., Peter FenwickMichael Nahm).


🧭 Philosophical and Metaphysical Implications

Terminal lucidity suggests that:

  • Consciousness may not fully depend on the structural integrity of the brain

  • The relationship between brain and mind is not one-way

  • Cognitive functions may be recoverable or accessible from a non-local source

This supports:

  • Cosmopsychism (consciousness is not produced, but channeled)

  • Survivalist views (consciousness can outlive the brain)

  • Spiritual perspectives (e.g., soul returns briefly before departing)


✨ Summary

ModelHow It Explains Terminal Lucidity
Mainstream neuroscienceStruggles to explain; lacks mechanism
Brain-as-filter theoryAs brain dies, filtering weakens; wider mind emerges
CosmopsychismCosmic mind reclaims local identity at death
Dualist / spiritual viewsSoul briefly reasserts itself before departing

Better than panpsychism? (Part 1)

 


Tonight´s second ChatGPT essay cuz why not. Overlaps with some previous stuff, but who cares? ;-)  

What are the arguments in favor of cosmopsychism?

Cosmopsychism is the philosophical view that the universe as a whole has a form of consciousness, and that individual minds (like yours and mine) are derivative aspects or fragments of that cosmic consciousness.

It’s a modern revival and refinement of ancient ideas like the World Soul (anima mundi) from Platonism and Stoicism, but it has gained serious traction in contemporary philosophy of mind and metaphysics as an alternative to both materialism and dualism.


🧠 What Cosmopsychism Proposes (in brief):

  • The cosmos is fundamental and conscious.

  • Human minds are localized manifestations or divisions of this universal consciousness.

  • This reverses the usual materialist view, which sees consciousness as arising from tiny physical pieces (like neurons).

  • Instead, it says consciousness is holistic and prior, and matter arises from or within it.


🔍 Arguments in Favor of Cosmopsychism

1. 🧩 It Solves the Combination Problem Better than Panpsychism

  • Panpsychism claims that all matter has some form of consciousness, and human minds emerge by combining these "tiny minds."

  • But this leads to the combination problem: how do trillions of micro-consciousnesses combine into one unified experience?

Cosmopsychism's answer:

There’s one unified cosmic consciousness already, and individual minds are divisions or derivations from that whole—not combinations.

This avoids needing to explain how little bits of awareness add up.


2. 🪞 It Aligns with the Unity of Consciousness

Human experience is unified—we don’t feel like a collection of smaller minds.

  • Cosmopsychism grounds this in the prior unity of the cosmos itself, which is ontologically fundamental.

  • Individual consciousness is a partial localization, not a bundle of parts.


3. 🌌 It Explains the Fine-Tuning of the Universe

  • Cosmopsychism suggests that the laws of physics are expressions of an underlying conscious mind.

  • This could explain why the universe seems finely tuned for life and awareness.

This is an alternative to:

  • Random chance (which seems implausible),

  • The multiverse (which is speculative and unfalsifiable),

  • Theism (which introduces a separate creator outside the cosmos).

Instead, the cosmos itself is the conscious ground of all that exists.


4. 🔄 It Provides a Non-Dualist Framework

  • Unlike substance dualism, it doesn’t split mind and matter into separate substances.

  • Unlike reductive materialism, it doesn’t eliminate consciousness or reduce it to neural patterns.

Instead, it suggests mind and matter are two aspects of the same cosmic entity.

This is a monist position: the universe is one thing, and that thing is both mental and physical.


5. 🧘 It Resonates with Mystical and Phenomenological Experience

  • Mystics across traditions (Vedanta, Sufism, Christian mysticism, Zen) describe a sense of union with a cosmic or divine mind.

  • Cosmopsychism provides a philosophical framework for these experiences without appealing to supernaturalism.


6. 🧠 It’s Compatible with Certain Interpretations of Physics

Some physicists and philosophers have suggested:

  • The non-locality in quantum mechanics (e.g., entanglement) reflects a kind of underlying wholeness in reality.

  • The observer problem (e.g., in the measurement of quantum states) might suggest that consciousness and the cosmos are deeply entangled.

Cosmopsychism sees the universe not as a mechanical machine with consciousness as an add-on, but as a unified conscious whole in which physical processes unfold.


🧾 Summary Table

Argument for CosmopsychismWhat It Addresses
Solves the combination problemPanpsychism’s biggest issue
Accounts for unity of consciousnessPhenomenological coherence
Explains fine-tuning without theism or multiverseOrigin of life-friendly laws
Non-dualist, monistic ontologyAvoids both dualism and reductionism

🧠 Philosophers Who Defend or Explore Cosmopsychism

  • Philip Goff – One of the leading voices in contemporary analytic philosophy defending cosmopsychism.

  • Galen Strawson – Open to panpsychist and cosmopsychist implications.

  • Itay Shani and Hedda Hassel Mørch – Developed sophisticated models of cosmopsychist ontology.

  • David Chalmers – Not a cosmopsychist himself, but sees it as a serious contender.

Let me know how deep you want to go—this is a rich and fast-growing field of thought.

What are the objections and challenges to cosmopsychism? How might cosmopsychism be empirically or conceptually tested?

Great questions—cosmopsychism is elegant, but it's not without serious philosophical challenges and epistemological hurdles. Let’s break this into two parts:


❗ Objections and Challenges to Cosmopsychism

Despite its appeal, cosmopsychism faces a number of critical objections. Some overlap with panpsychism, while others are unique.


1. 🧠 The Derivation Problem (Reverse of the Combination Problem)

How do individual, limited minds arise from a unified, cosmic mind?

In panpsychism, the challenge is to combine micro-consciousnesses into a unified self.
In cosmopsychism, the problem flips:

How does unity become multiplicity?
How does the one cosmic subject give rise to many seemingly separate minds?

This is sometimes called the "decombination problem" or "derivation problem," and it's notoriously difficult.


2. 🧩 Lack of Mechanism or Process

How does the cosmic consciousness "produce" brains, matter, or laws of physics?

Critics ask: if the universe is a conscious being, why does it produce matter, and why does this matter behave in a way that follows precise, mathematical laws?

  • Is the brain a kind of filter for the cosmic mind?

  • Is it a local modulation, like a whirlpool in a river?

These metaphors help, but they aren't yet formalized into clear models.


3. 🔒 The Privacy of Consciousness

Cosmopsychism depends on attributing consciousness to the entire universe.

But we can't observe or interact with such a global mind.

This parallels the "problem of other minds" in philosophy: we infer other people are conscious, but we can't prove it.
Now extend that to the entire cosmos, and the evidentiary gap widens.


4. 🧪 Apparent Causal Closure of Physics

According to mainstream physics:

  • The brain’s activity seems explainable by physical causes alone.

  • There’s no obvious role for a cosmic consciousness in neuronal firing or cognition.

So: why invoke cosmopsychism if the local physics seems causally sufficient?

Defenders might argue that consciousness is not a causal force, but a ground or field in which physicality unfolds—yet this raises further metaphysical complications.


5. 📏 Vagueness and Lack of Predictive Power

  • Cosmopsychism doesn’t yet lead to testable predictions.

  • Its terms (“cosmic mind”, “localization”) are metaphorical unless formalized.

Skeptics say that unless the theory makes clear conceptual distinctions or predicts phenomena, it risks being poetic metaphysics, not science or analytic philosophy.


6. 🧍 Persistence of Personal Identity

If we are just local expressions of the one cosmic mind, then:

  • Why do we have stable, bounded identities?

  • Why don’t we all feel we are the universe?

Cosmopsychism must explain the illusion (or reality) of individuation, suffering, moral responsibility, and memory.


🔬 Can Cosmopsychism Be Empirically or Conceptually Tested?

Testing cosmopsychism is tricky—but not impossible. There are indirect and conceptual approaches that could lend it support (or disconfirm it):


1. 🧠 Neuroscience: Limits of Brain-Based Models

If neuroscience fails to explain consciousness fully, especially:

  • Why it feels like anything to be a brain, or

  • How unified experience arises from distributed processes,
    then alternative frameworks like cosmopsychism may gain plausibility.

Think of it as a theory of last resort—if materialist models fail, the field may look upward to the cosmos.


2. 🔄 Brain-as-Filter Hypothesis

Cosmopsychism could predict that:

  • Brains don’t generate consciousness but filter, localize, or shape it.

This leads to empirical hypotheses:

  • Reduced brain activity correlates with more consciousness (e.g., in psychedelic states, NDEs, or meditation).

  • Some studies (e.g., with psilocybin or DMT) show this counterintuitive pattern.

This supports the idea that consciousness is fundamental, and the brain is not a generator but a modulator.


3. ⚛️ Quantum Physics & Non-Locality

Some interpretations of quantum mechanics (e.g., Bohm’s implicate order, or the observer problem) suggest a holistic, non-local reality.

Cosmopsychism could provide a metaphysical basis for:

  • Quantum entanglement

  • Observer-dependence of reality

These aren’t proofs, but theoretical coherence is a kind of weak confirmation.


4. 🤯 Phenomenology and Mystical Reports

Many mystical, meditative, or psychedelic experiences report:

  • Loss of ego boundaries

  • Union with the cosmos

  • Experience of an infinite mind or field of awareness

Cosmopsychism offers a naturalist interpretation of these states, unlike dualist or supernatural ones.

If large populations report similar structure to such experiences, this might count as empirical phenomenology that supports the model.


5. 📐 Formalization via Mathematics or Physics

Some physicists and philosophers (e.g., Michael Levin, Giulio Tononi, and Philip Goff) are working toward formalizing consciousness into physical models.

If someone successfully:

  • Integrates consciousness into fundamental physics

  • Or proposes a holistic, field-based theory of consciousness

…then cosmopsychism could emerge as the simplest interpretation.


✅ Summary Table

Objection / ChallengeResponse / Potential Solution
Derivation problem (unity to many)Needs better formal modeling
No causal role for cosmic mindMay be a non-causal ground, not an agent
Vagueness of conceptsNeeds conceptual rigor and definitions
No testable predictionsIndirect support via neuroscience, phenomenology
Apparent success of brain-only modelsThose may still fail to explain subjectivity

🔚 Final Thought

Cosmopsychism is a bold, elegant metaphysical hypothesis.

  • It sits between mysticism and metaphysics, but with increasing philosophical legitimacy.

  • Whether it’s testable, true, or merely poetically resonant depends on whether it can be refined into a precise framework with empirical handles.
