Study Notes

  • Consciousness encompasses both physical and intangible aspects.

Dualism

  • Aspects of consciousness exist outside the physical or material realm, suggesting something "more".
  • Substance Dualism posits a material world (brain) and an immaterial world (memories, feelings).
  • René Descartes believed in substance dualism, with the pineal gland facilitating interaction between the tangible and intangible.
  • A challenge to dualism is the Problem of Interaction, where physical changes (e.g., hormones) affect consciousness.
  • Response to the Problem of Interaction, René Descartes proposed interaction can be accounted for by the pineal gland.
  • The dualistic paradigm suggests the conscious cannot be fully explained by the material.

Materialism (or Physicalism)

  • All aspects of consciousness are within the physical or material realm.
  • Materialism contends that everything can be explained by physical processes.
  • The Problem of Emergence questions how the material accounts for the "self".

The "Easy" vs. The "Hard" Problem

  • The "easy" problem involves identifying the neural correlates of consciousness and specific conscious experiences, such as relating brain functions to subjective experiences.
  • The "hard" problem addresses how an objective physical body/brain gives rise to subjective conscious experience.

Case Studies

  • A woman's itch disappearing after neural sensitivity removal suggests habitual scratching can create false perceptions.
  • Individuals with a condition causing them to not see the left side of an image still unconsciously chose a safe house, despite not consciously seeing the burning one.
  • This suggests that people may still have a degree of functionality without the need for conscious action or perception.

"Philosophical Zombie" Thought Experiment

  • Challenges physicalism by asking if a perfect human replica, whether silicone or flesh, necessarily has consciousness.
  • Dualists argue such creations may lack consciousness, while physicalists would say they do.

Mary's Room Thought Experiment

  • Addresses a person has all the information about colour perception, yet has never experienced it, to consider physicalist or dualist.
  • Qualia are the subjective, ineffable qualities of experience, like the personal experience of colour.

Deflationary Arguments

  • These defend physicalism by arguing we overstate the mystery and power of consciousness.
  • By resisting the mystification of consciousness, it becomes explainable in physical terms.
  • Deflationary arguments deny the existence of a "hard problem" or "zombies”.

"Conscious Awareness"

  • Can be limited, where focusing on one thing causes us to miss others that may be very obvious.

Recap

  • Dualist vs Physicalist theories
  • Challenges to physicalism
  • Conceivability of the Philosophical Zombie
  • The "something more" of qualia
  • The "hard problem"
  • "Deflationary" defenses of physicalism

Analogous Argument

  • Consciousness is not more than can be explained by physical brain processes.

What is Conscious

  • It is debated how to decide what is conscious, even if definitive "knowing" is impossible.

Dogmas

  • There are existing beliefs that mechanical creations cannot be conscious.

Neural Replacement Thought Experiment

  • Considers if replacing parts of the brain with artificial implants affects consciousness.

Ship of Theseus Thought Experiment

  • Explores whether an object remains the same if its components are gradually replaced.

Biological Organism Thought Experiment

  • Considers if organisms are still the same when all their cells are replaced.

“Substance-Independency” of Consciousness

  • Posits that consciousness does not depend on specific materials as long as internal causal relations are correct.

“Thinking” versus “Consciousness”

  • “Thinking” / “Intelligence” can be measured using tests like the "Turing Test" instead of "Consciousness"

Turing Test

  • Turing believed if AI was indistinguishable from human response, then it would be Strong AI.
  • Turing Test employs a behavioral or functional metric, aiming to measure imitation.
  • The Chinese Room argument posits, despite syntactic sophistication it is no measure of genuine understanding.

Homeostasis

  • Homeostasis (equilibrium) and need-based conception of “like to be-ness”
  • Designing an artifical intelligence with conflicting needs, so that it may plan how to solve its conflicts.
