Frank Jackson's "Mary the Neuroscientist" thought experiment, from his "Epiphenomenal Qualia" paper, has been continually debated since its publication in 1982, and appears to be a significant motivation for believing physical science alone will never explain consciousness (the 'explanatory gap') and in seeking non- or extra-materialist explanations of consciousness.
Recently, panpsychism, in some form or another, has been gaining some acceptance as a viable counter to materialism in matters of the mind (if not beyond!) This raises an obvious follow-on question to that posed by Jackson (and does so regardless of whether you are much influenced by the original): If we substitute Panpsychist Mary, who knows all of the knowledge that panpsychism could ever reveal, for Jackson's Neuroscientist Mary, will she be surprised (or have her curiosity answered) by what it is like to see colors when she first does so? In particular, for those who feel that her curiosity could be entirely satisfied by the knowledge gained through her studies, do you feel that this knowledge would be outside of the scope of that available to Neuroscientist Mary, and if so, why?
I find it difficult to select one particular answer here, as none seem to encompass all the possible responses being given collectively. Nevertheless, I feel obliged by the Stack Exchange format to make a choice.
Most of the replies approach the question from a physicalist point of view. Given that physicalists of all stripes reject the claim that the Knowledge Argument succeeds, it does not seem surprising when they find the Panpsychist Mary variant to be uninformative. No single reply considers both panpsychist and physicalist viewpoints, but Dcleve's reply covers a range of possible panpsychist replies, and I have selected it on that basis. In doing so, I am most definitely not adopting any of them as my own or advocating that anyone should do so, and nor am I rejecting those made in the other replies. I urge anyone who is interested in the question to look at all of them.
