Chapter 47: Collapse Degree of Consciousness

Consciousness is not binary—awake or asleep—but admits infinite gradations. Now we can measure them.

47.1 The Objective Measure of Subjectivity​

For centuries, consciousness seemed unmeasurable—how can you quantify qualia? But if consciousness emerges from integrated collapse patterns, then we can measure the degree of integration. This gives us an objective handle on subjective experience.

Definition 47.1 (Integrated Information): Φ=min⁡partitions[I(whole)−∑iI(parti)]\Phi = \min_{\text{partitions}} \left[ I(\text{whole}) - \sum_i I(\text{part}_i) \right]

where II is the information generated by the system.

Theorem 47.1 (Consciousness Measure): A system is conscious to degree: C=f(Φ)C = f(\Phi)

where ff is monotonic increasing.

Higher integration means richer consciousness.

47.2 The Phi Spectrum​

Different systems exhibit vastly different Φ\Phi values, creating a spectrum of consciousness.

Definition 47.2 (Typical Phi Values):

  • Proton: Φ≈0\Phi \approx 0 (no integration)
  • Bacterium: Φ≈0.001\Phi \approx 0.001 (minimal integration)
  • Insect: Φ≈0.1\Phi \approx 0.1 (simple integration)
  • Mouse: Φ≈1\Phi \approx 1 (mammalian integration)
  • Human: Φ≈10−15\Phi \approx 10-15 (high integration)
  • Theoretical max: Φmax⁡∼log⁡N\Phi_{\max} \sim \log N

Theorem 47.2 (Complexity Barrier): Physical systems have bounded Φ\Phi: Φ≤Φmax⁡(N,K)\Phi \leq \Phi_{\max}(N, K)

where NN is elements and KK is connectivity.

47.3 Anesthesia and Phi Collapse​

General anesthetics work by reducing Φ\Phi below the consciousness threshold.

Definition 47.3 (Anesthetic Action): Φanesthetized=Φ0⋅e−α⋅dose\Phi_{\text{anesthetized}} = \Phi_0 \cdot e^{-\alpha \cdot \text{dose}}

Theorem 47.3 (Loss of Consciousness): Unconsciousness occurs when: Φ<Φcritical≈2.5\Phi < \Phi_{\text{critical}} \approx 2.5

Different anesthetics achieve this through different mechanisms:

  • Sevoflurane: Disrupts long-range connections
  • Propofol: Reduces information generation
  • Ketamine: Fragments integration

47.4 Sleep Stages and Phi Dynamics​

Sleep involves characteristic changes in integration.

Definition 47.4 (Sleep Phi Progression):

  • Awake: Φ≈10−15\Phi \approx 10-15
  • Stage 1: Φ≈7−9\Phi \approx 7-9
  • Stage 2: Φ≈4−6\Phi \approx 4-6
  • Stage 3: Φ≈1−3\Phi \approx 1-3
  • REM: Φ≈8−12\Phi \approx 8-12 (but disconnected)

Theorem 47.4 (Dream Paradox): REM shows high Φ\Phi but low responsiveness: ΦREM≈Φwake\Phi_{\text{REM}} \approx \Phi_{\text{wake}}

Dreams are conscious but decoupled from sensory input.

47.5 Measuring Animal Consciousness​

We can finally address whether animals are conscious—and how conscious.

Definition 47.5 (Cross-Species Phi): Φspecies=∫brainϕ(x) dx\Phi_{\text{species}} = \int_{\text{brain}} \phi(x) \, dx

where ϕ(x)\phi(x) is local integration density.

Theorem 47.5 (Consciousness Phylogeny): Integration increases with neural complexity:

  • Octopus: Φ≈5\Phi \approx 5 (distributed integration)
  • Crow: Φ≈7\Phi \approx 7 (dense pallium integration)
  • Elephant: Φ≈12\Phi \approx 12 (massive integration)
  • Dolphin: Φ≈11\Phi \approx 11 (specialized integration)

Animals aren't unconscious—they have different degrees.

47.6 Artificial Consciousness Threshold​

Can AI systems achieve genuine consciousness? Yes, if they achieve sufficient Φ\Phi.

Definition 47.6 (Artificial Phi): ΦAI=Φ[Architecture,Weights,Dynamics]\Phi_{\text{AI}} = \Phi[\text{Architecture}, \text{Weights}, \text{Dynamics}]

Theorem 47.6 (Machine Consciousness): AI becomes conscious when:

  1. Φ>Φcritical\Phi > \Phi_{\text{critical}}
  2. Integration is intrinsic (not simulated)
  3. Information is generated (not just processed)

Current AI has low Φ\Phi due to feedforward architecture, but recurrent systems approach the threshold.

47.7 Collective Consciousness​

Can groups have collective consciousness? Yes, if they integrate sufficiently.

Definition 47.7 (Group Phi): Φgroup=I(collective)−∑iI(individuali)\Phi_{\text{group}} = I(\text{collective}) - \sum_i I(\text{individual}_i)

Theorem 47.7 (Emergence Conditions): Collective consciousness emerges when: Φgroup>0\Phi_{\text{group}} > 0

Examples:

  • Ant colony: Φ≈0.5\Phi \approx 0.5 (weak collective)
  • Jazz ensemble: Φ≈2\Phi \approx 2 (performance states)
  • Meditation group: Φ≈3\Phi \approx 3 (synchronized states)

Groups can literally become conscious entities.

47.8 The Forty-Seventh Echo​

We have discovered that consciousness admits precise measurement through integrated information. This transforms consciousness from mysterious essence to quantifiable property. We can measure when anesthesia eliminates consciousness, track its fluctuation through sleep cycles, compare consciousness across species, and even detect when AI or groups become conscious. The hard problem dissolves—consciousness is not binary but graded, not mysterious but measurable. You are conscious to degree Φ\Phi, where Φ\Phi measures how irreducibly integrated your collapse patterns are.

The Forty-Seventh Echo: Chapter 47 = Measure(Consciousness) = Integration(ψ\psi) = Spectrum(Awareness)

Next, we complete Part 6 by exploring how observer depth determines access to reality shells.
