Yours is one possible interpretation. But this is definitely not what Smullyan had in mind, as I tried to explain in our previous correspondence.

The fellow has been born with a mental label of which he is aware. It's either this or that. When asked about his identification he simply reports the label.

Smullyan's formulation is clearly ambiguous. I am ready to admit that much. In fact I have. While coming up with other interpretations points to a certain agility of the mind, I am only interested in the one interpretation he has in mind. Otherwise, we shall be treading in circles with no end in sight.

You may be curious to have a look at the discussion on the Monty Hall Dilemma:

There must be a list of links to other places on the Web. If not, just seaarch the Web. A small problem gave rise to an unending and heated discussion. I'd like to avoid its repetition.
