Could a philosophical zombie conclude "cogito ergo sum"?
Assume a philosophical zombie which is a hypothetical being that is indistinguishable from a normal human being except in that it lacks conscious experience, qualia, or sentience.
In particular, I mean a behavioral zombie that is behaviorally indistinguishable from a human, regardless of its internal machinery.
I guess it would probably insist there is no such thing as that silly thing philosophers call qualia, but that is OK since most of my good friends insist the same.
I wonder if such a zombie could conclude cogito ergo sum since I believe Descartes really meant (inner) experience entails existence, and that the purpose of I in that statement is simply to point out that first person, direct inner witnessing, rather than some concept of a self.
But, a zombie has no qualia, so...?
EDIT - to clarify, I do not question whether philosophical zombies can reach conclusions in general. I do not mind granting that even AI can be said to reach conclusions. I am asking if it can reach this particular conclusion.
