Alice and Boolean Logic

"I quite agree with you," said the Duchess; "and the moral of that is-- 'Be what you would seem to be'-- or if you'd like it put more simply-- 'Never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise."'
-Alice in Wonderland

This would appear to be some form of negation. It reminds me of Boolean Logic only including not only logical negation, but also linguistic tense negation. I have not actually checked the statements to see if they actually say the same thing, but I sure found it funny.
