19. Consciousness Thinking

• So where's consciousness in my loopy tale?
• Consciousness Dance of symbols in the cranium.
• External events trigger symbol retrieval from
  dormancy.
• Neural signals must be perceived at level of
  symbols.

9
19.2. Enter the Skeptics.

• What matters is to spot the gist.
• Symbols trigger more symbols.
• Jilting of DRH's research group promising grad
  student applicant.
• The central loop of cognition
• Categorize, find precedents, analogies.
• Simplify without letting essence slip away.

10
20. Courteous Crossing of Words.

• Dramatis personae
• Strange loop 641 There may be several Is.
  (Hofstadter).
• Strange loop 642 There is but one I.
  (Skeptic).

11
20. Location of I.

• I Mostly housed in that person's brain.
• Partially localized outside one's body.
• The marble illusion feels like a marble, but
  isn't.
• I Created out of nothing.
• I Hallucination, perceived by a hallucination.

12
Perception.

• I can and does watch itself.
• One can't turn off one's perception machinery.
• I set of very high-abstractions.
• Requires referential stability.
• Example Gödel self-referential sentences.
• Example DNA blueprint.
• Example Sadegh-zadehs quasi-self-reproducing
  systems.

13
21. Brief Brush with Cartesian Egos.

• Well-told stories pluck powerful chords.
• Star-Trek-style teleporter.
• What if the teleporter makes TWO copies?
• What pushovers we are!
• Which copy is the real I?

14
21.4. Murky Whereabouts of Cartesian
Egos.

• Am I on Venus, or am I on Mars?
• Personal identity is an indeterminate notion.
• Today's I is different from yesterday's I.
• The radical nature of Parfit's views.
• Self-confidence, humility, and self-doubt.

15
21.8 Morphing Parfit into
Bonaparte.

• Radical redesign of Douglas R. Hofstadter.
• John Searle's Chinese Room Experiment.
• On who and on how.
• There is something it is like to be a machine.
• CompareAvrupalilastirilamiyanlardansiniz.
• Double or nothing Cartesian I is a
  hallucination.

16
21.12. Trains Who Roll.

• Which future person is the true I?
• Train from Milano east to Venice North to
  Bolzano.
• Which train is the REAL train?
• The Glow of the Soular Corona
• Teachers make many partial copies of their I.

17
BILL MOORES CRITIQUE.

• I am a Strange Loop expansion of GEB concepts.
• Self-referential systems are complex
• Gödel's sentence Escher drawings Bach fugues.
• Self-referential systems have perception.
• Self-referential systems can reproduce and
  quasi-reproduce.

18
Todays I is different from
Yesterdays I.

• Time flies like an arrow, f(t).
• Time as a landscape the entire function f over
  t.
• F as a math relation F(t) with multiple values
  for some values of t.

19
Bill Moore has a Cartesian Ego.

• There is only one known Ego.
• Parfit's fantasy teleportation
• NOT supported by observational data.
• NOT on the same level as Einstein!
• N.N. Taleb's Ludic Fallacy.

20
Bioteleportation Identical
Twins.

• Identical twins a congenital anomaly, 1240
  live births.
• Non-identical twins environmental, e.g.,
  fertility drugs, 1160 live births.
• Incomplete identical twins conjoined twins.
• Types thoracopagus, omphalopagus, xiphopagus,
  ischiopagus, parasitic, ..., acardius amorphus.
• In theory, EVERY live birth has an identical
  twin.

21
Comparison Parfit to Einstein.

• Overblown.
• Einstein made experimental predictions.
• Parfit no such predictions.

22
Trains Who Roll

• Compare Sadegh-zadeh's Pe-Kawe (car).
• First-level self-representation
• Internal representation of itself.
• Current speed in the tachometer,
• Current gasoline consumption on gauge,
• Cooling water temperature gauge,
• Motor revolution count, etc.

23
Sadegh-zadehs
Pe-Kawe (Car).

• First-level self-representation.
• Second-level self-representation.
• Third-level self-representation....
• ... Geist (consciousness, mind, spirit...).

24
Sadegh-zadehs Global Machine.

• System.
• Cyclic causal system.
• Distributed system.
• Autonomous system.
• Quasi-self-reproductive system.
• Darwinian evolutionary system.
• Hypercyclically organized system.

25
Darwinian Machines.

• Biosphere-Technosphere-Network.
• Biosphere-Technosphere-Hypercycle.
• The Global-Machine.
• The Global-Machine is a Life-form.
