the discussion we've been having in class

fresh from the new york times: can science explain consciousness?

We trust science because its claims are based on experience. But experience itself is a subjective reality that seems to elude the objectivity of scientific understanding. We know that our experiences—of seeing red, feeling pain, falling in love and so forth—depend on physical systems like the brain that science can, in principle, exhaustively explain. But it’s hard to make sense of the idea that experiences themselves could be physical. No doubt experiences correlate with objective physical facts, but, as subjective phenomena, how could they be such facts? When I feel intense pain, scientists may be able to observe brain-events that cause my pain, but they cannot observe the very pain that I feel. What science can observe is public and objective; what I feel is private and subjective.

then, there's the speculative question, What’s to say that future scientific developments won’t allow us to understand how experiences can be entirely physical?
