What we are left with are three types of thought experiments in philosophy of mind: (i) Those that do establish what their authors think (Chinese Room), even though this is a more limited conclusion than what its detractors think (the room doesn’t understand Chinese, in the sense of being conscious of what it is doing; but it does behave intelligently, in proportion to its computational speed and the progammer’s ability). (ii) Those that do not establish what their authors think (Mary and the bats), but nonetheless are useful (they make clear that third person description and first person experience are different kinds of “knowledge,” and that it makes no sense to somehow subsume one into the other). (iii) Those that are, in fact, useless, or worse, pernicious (p-zombies) because they distract us from the real problem (what are the physical bases of consciousness?) by moving the discussion into a realm that simply doesn’t add anything to it (what is or is not logically conceivable about consciousness?).
You can read the details of these famous thought experiments here. I feel certain that Pigliucci is right about types (i) and (ii). I am sure that there are thought experiments of type (iii), but I will have to think it over whether Chalmers’ p-zombie example is apt.
