Doublespeak (cont.)
Logical Fallacies, Propaganda
Devices, and Language Misuse
To know and not to know, to be conscious of
complete truthfulness while telling carefully
constructed lies, to hold simultaneously two
opinions which cancelled out, knowing them to be
contradictory and believing in both of them, to use
logic against logic, to repudiate morality while
laying claim to it, to believe that democracy was
impossible and that the Party was the guardian of
democracy, to forget, whatever it was necessary to
forget, then to draw it back into memory again at
the moment when it was needed, and then
promptly to forget it again, and above all, to apply
the same process to the process itself--that was the
ultimate subtlety; consciously to induce
unconsciousness, and then, once again, to become
unconscious of the act of hypnosis you had just
performed. Even to understand the word
"doublethink" involved the use of doublethink.

Weasel Words
"A weasel word is a modifier that practically negates the claim that follows. The
expression 'weasel word' is aptly named after the egg-eating habits of weasels. A
weasel will suck out the inside of an egg, leaving it appear intact to the casual
observer. Upon examination, the egg is discovered to be hollow. Words or claims
that appear substantial upon first look but disintegrate into hollow
meaninglessness on analysis are weasels" (Jeffrey Schrenk).
