Sure, mental states are physical configurations of the brain, which is a piece of matter, so the question of whether a certain piece of matter in the universe is or was in a certain physical configuration is in principle amenable to scientific enquiry.
My question is, what is the point? I mean, in some circumstances it may certainly useful to determine whether somebody is lying or telling the truth, but in general, if somebody beliefs are epistemically correct, does it matter what specific subjective experiences are associated to them?
