i) It is conceivable that P & not-Q.
ii) If it is conceivable that P & not-Q, then it is metaphysically possible that P and not-Q.
iii) If it is metaphysically possible that P & not-Q, then materialism is false.
iv) So materialism is false.
i) If there are more than physical facts
ii) and that these things can't be deduced from physical facts
iii) then materialism must be false.
P ⊃ Q
- There is an epistemic gap between physical and phenomenal truths.
- If there is an epistemic gap between physical and phenomenal truths, then there is an ontological gap, and materialism is false.
- Materialism is false.
The obvious point to make here is the slide from the epistemic gap to an ontological gap. What does that mean?
