Mary has lived her entire life in a black and white room. In that room, she learned everything there is to know about the neurophysiology of perception. She knows everything that happens in the brain when a person sees a blue sky. One day, Mary leaves the black and white room and sees the blue sky. Has Mary learned something new?

Frank Jackson posed this famous thought experiment as a challenge to physicalists, such as David Papineau, who argue that qualitative experiences are identical to brain states. If this is really so, the argument goes, Mary isn’t learning anything new, since she already knew everything about the relevant brain states. But she does seem to learn something new: what it’s actually like to see blue. In this interview, Papineau addresses this challenge and explains why he thinks that, despite our intuitions to the contrary, qualitative experiences are simply neural states under a different description.

Be sure to listen to the first half of this interview, where David explains Russellian monism and the causal argument.
