I suspect you are faking faking doubts, but of course I cannot provide
any argument.
I mean it is hard for me to believe that you are a zombie, still less
a zombie conscious to be a zombie!

  I don't know if you do this to please me, but you illustrate quite
well the Löbian "consciousness" theory.
Indeed the theory says that "consciousness" can be very well
approximated logically by "consistency".
So a human (you are human, all right?) who says "I am a zombie", means
"I am not conscious", which can mean "I am not consistent".
By Gödel's second theorem, you remain consistent(*), but you loose
arithmetical soundness, which is quite coherent with your
ultrafinitism. If I remember well, you don't believe that there is an
infinity of natural numbers, right?

We knew already you are not arithmetically sound. Nevertheless it is
amazing that you pretend that you are a zombie. This confirms, in the
lobian frame, that you are a zombie. I doubt all ultrafinitists are
zombie, though.

It is coherent with what I tell you before: I don't think a real
ultrafinitist can know he/she is an ultrafinitist. No more than a
zombie can know he is a zombie, nor even give any meaning to a word
like "zombie".

My diagnostic: you are a consistent, but arithmetically unsound,
Löbian machine. No problem.

There are not many zombies around me, still fewer argue that they are
zombie, so I have some questions for you, if I may.

1) Do you still answer yes to the doctor if he proposes to substitute
your brain by a sponge?
2) Do humans have the right to torture zombie?
3) Do you have any "sort-of" feeling, insight, dreams, impression,
sensations, subjective or mental life, ... ?
4) Does the word "pain" have a meaning for you? In particular, what if
the doctor, who does not know that you are a zombie, proposes to you a
cheaper artificial brain, but warning you that it produces often
unpleasant hard migraine? Still saying yes?

(*) For example: Peano Arithmetic + "Peano Arithmetic is inconsistent"
gives a consistent theory. If not, Peano Arithmetic + "Peano
Arithmetic is inconsistent" would prove "0=1", and thus PA would prove
~(provable "Peano Arithmetic is inconsistent" ), and thus PA would
prove its own consistency, contradicting Gödel II.
