Which Alice?

ALICE IN PUZZLE-LAND
Alice thought about this for a moment. "No," she answered, "of
course not!"
"Ah, I've caught you!" exclaimed Humpty Dumpty proudly.
"How so?" asked Alice.
"Look, child, you answered no, did you not?"
"Of course I did!" replied Alice.
"And did you answer correctly?" asked Humpty Dumpty.
"Certainly," replied Alice, "why not?"
"Ah, that's where I have you!" he replied. "Since you answered no
and you answered correctly, then no is the correct answer to the
question!"
"That's what I'm saying!" said Alice.
"Well, if No is the correct answer, then when I asked you whether
it was, you should have said yes, not no!"
Alice thought about this for a while and suddenly saw the point.
"Of course!" said Alice. "You're absolutely right! I should have said
yes, not no!"
"Ah, I've caught you again!" replied Humpty Dumpty triumphantly.
"What!" said Alice in amazement.
"Of course I have, child! Yes can't possibly be the right answer!"
"Why not?" asked Alice, more puzzled than ever.
"To answer yes is to affirm that No is the correct answer, but if no
is the correct answer, you should give it rather than the incorrect
answer Yes!"
"Oh!" said Alice, more bewildered than ever. "So I guess I was
right the first time; I should have answered no after all."
"No, you shouldn't have," said Humpty Dumpty sharply. "I've
already proven that!"
"I give up!" said Alice wearily. "What is the correct answer?"
"Why, there is no correct answer," he replied in a tone of
complete triumph, "and that's the beautiful part of it!"
"Where did you ever get that baffling question?" asked Alice.
"I thought it up myself!" replied Humpty Dumpty proudly. "And
wasn't I right?"
"Right about what?" asked Alice.
"Didn't the question make you think?"
