Episode notes
Mind-Body Interaction Revisited
- William Lane Craig argues Descartes' dualism was mischaracterized by Carroll and that the mind can be spatially located and interact with the body.
- He contends phenomenology and first-person awareness provide strong reasons to posit a distinct mind or self.
Pianist And Piano Analogy
- Sir John Eccles compared the relationship of the mind and brain to a pianist and a piano, illustrating dualist interactionism.
- William Lane Craig uses this analogy to show the self uses the brain as an instrument and is impaired when the brain is damaged.
Unmoved Mover And Inertia
- Craig explains that Aristotelian physics undergirded Thomas Aquinas' unmoved mover argument, which Newtonian inertia later undermined.
- He notes other theistic arguments like contingency, design, and the Kalam remain unaffected by the physics shift.
