Document Summary
Physicalism: the cluster of views that all mental states are physical states: corollary: the actual world is entirely physical, conjecture: complete physical knowledge is complete knowledge, mind brain identity, functionalism, enactivism, reductionism, supervenience, non-reductionism: Objection to physicalism: the knowledge argument: It seems, however, that mary does not know all there is to know. For when she is let out of the black-and-white room or given color television, she will learn what it is like to see something red, say. This is rightly described as learning she will not say ho, hum (291). All along their experiences (of many of them, those got from tomatoes, the sky ) had feature conspicuous to them but until now hidden from her (292-293) The knowledge operator: kxy = x knows that y: kxy is not identity preserving (referential opacity) If you want to know all the physical facts, then you know all the identity statements too.
