A philosophical zombie [1] is essentially a mobile, autonomous human body devoid of consciousness. Critically, still giving all of the external cues that it has in fact consciousness. It is supposed to prove that physicalism doesn't work. "The sense of consciousness" is used like a "soul, with extra steps".
In my humble opinion, which I have no way to prove or disprove, consciousness ("as a soul with extra steps") does not exist, and we are all philosophical zombies. Consciousness "as an amalgamation of complex biological signals and neural interactions that has evolved through millions of years as a successful survival strategy" does exist, and that is all that is needed.
>For example, if a philosophical zombie were poked with a sharp object, it would not feel any pain, but it would react exactly the way any conscious human would.
in the Wikipedia article because I don't get on well with the sharp poking. On the basis of Occam's razor I assume all other humans and higher animals are similar. It would be odd if evolution had made me different from all the others.
What I am denying is that there's anything metaphysical about the whole process.
The opponents of physicalism like Chalmers start from the axiom that consciousness is, in fact, separated from the physical world. Then they use the zombie to "demonstrate" (using circular logic, in my opinion) that physicalism is not possible.
I do believe that your (our) feelings, emotions, and our sense of self all emanate from the physical world. So in that sense "we are all the zombies that Chalmers talks about".
"but it would react exactly the way any conscious human would"
So the pain would be registered, and reacted to.
The only difference is in how the world "feel" is interpreted.
For Chalmers, the difference between a "zombie" and a "regular human", according to Chalmers, is that for the "zombie" is just "meat reacting to things". The "human" on the other hand is "meat somehow connected to something outside of the meat called consciousness that is the only thing that really feels".
I (and the author of the article) disagree. Consciousness can be "just meat". No need to add an "external thing".
Serves me well for answering a comment before reading the article. This is basically what the author says, even pointing to the Philosophical zombie and all. Shame on me.
