what is type identity
all mental states are identical to brain states although brain states and mental states are not synonymous (not an analytical reduction)
what is the c-fibres and pain example
for someone to say that c-fibres are firing is just a technical term for feeling pain. so a type identity theorist would say that they are identical, in the same way lightning is identical to electrical discharge
JCC SMART-sensations and brain processes.
correlations
water is h20 example
mental states and brain states are contingently identical.
mental states ontologically reduce to brain states.
one ontological reduction- water=h20. they are not correlations. not analytical as its not a logical contradiction to say water is not h20
what is ockhams razor
the simplest answer is the best option, one with the least .
if two theories make the same prediction, then the one with the fewest entities is often the best
the location problem
example c-fibers
pain doesn’t appear to be in the same place as the c-fibres, if you locate my c-fibres it doesn’t seem like you’ve located my subjective mental sensation of pain.
therefore they are not the same.
