I think you really you mean nomologically possible. I'm not uncomfortable with them, I just maintain a little skepticism. For one thing what is nomologically possible or impossible is often reassessed. Less than a century ago the experimental results Elizer, Vaidman, Zeilenger, et al, on delayed choice, non-interaction measurement, and other QM phenomena would all have been dismissed in advance as "logically" impossible. >I think that's understandable, but ultimately, I'm on the > philosopher's side.

My puzzlement about how to answer Bruno's question comes from the ambiguity as to what we mean by a philosophical zombie. Do we mean its outward actions are the same as a conscious person? For how long? Under what circumstances? I can easily make a robot that acts just like a sleeping person. I think Dennett changes the question by referring to neurophysiological "actions". Does he suppose wetware can't be replaced by hardware? In general when I'm asked if I believe in philosophical zombies, I say no, because I'm thinking that the zombie must outwardly behave like a conscious person in all circumstances over an indefinite period of time, yet have no inner experience. I rule out an accidental zombie accomplishing this as to improbable - not impossible. In other words if I were constructing a robot that had to act as a conscious person would over a long period of time in a wide variety of circumstances, I would have to build into the robot some kind of inner attention module that selected what was important to remember, compressed into short representation, linked it to other memories. And this would be an inner narrative. Similary for the other "inner" processes. I don't know if that's really what it takes to build a conscious robot, but I'm pretty sure it's something like that. And I think once we understand how to do this, we'll stop worrying about "the hard problem of consciousness". Instead we'll talk about how efficient the inner narration module is or the memory confabulation module or the visual imagination module. Talk about consciousness will seem as quaint as talk about the elan vital does now.
