Crash Course Philosophy: Mind-Body Problem

Introduction

• Lecture sponsored by Squarespace.
• Story of Phineas Gage who survived an iron rod passing through his skull.
• Incident led to significant personality changes, linking physical brain changes to personality shifts.

Main Philosophical Question

• Where does our mind reside?

Reductive Physicalism

• Definition: The view that the world is only made of physical stuff.
  • Bodies, brains, hormones, neurotransmitters explain all human features.
• Incident with Phineas Gage supports this view.
• Similar to psychiatric treatment: Change in brain chemistry affects mood.

Substance Dualism

• Origin: Rene Descartes - Cogito ergo sum (I think, therefore, I am).
• Belief in two types of substances: physical (matter) and mental (mind).
• Interactionism: Mind and body interact within us.
  • Mental states can affect physical states and vice versa.
• Challenge: Known as the Mind-Body Problem.
  • How can mind and body interact if they are different substances?

The Mind-Body Problem

• Question of interaction between mental and physical substances.
• Descartes’ solution was the pineal gland as a portal.
• Modern philosophers struggle to solve this problem.

Epiphenomenalism

• View: Physical states give rise to mental states; mental states don't affect physical states.

Mysterianism

• Proponent: Colin McGinn.
• Claim: Consciousness is unsolvable by human minds.
  • Brains are compartmentalized, unable to integrate subjective and objective knowledge.

Flash Philosophy: The Mary Thought Experiment

• Proponent: Frank Jackson.
• Scenario: Mary, a scientist, learns everything about color in a black and white room.
• Question: Does she learn something new upon seeing color?
• Argument Against Physicalism: Qualitative experience or qualia cannot be fully explained physically.
• Physicalists counter that if physicalism is true, she learns nothing new.

Conclusion

• The mind-body problem remains unsolved.
• Physicalism hasn’t been definitively proven.
• Open questions to consider:
  • Is the mind a separate substance?
  • Can human complexity be purely physical?
