"High thoughts must have high language"
                                              Aristophanes 405 BC

"The whole literature of the past will have been destroyed. Chaucer, Shakespeare, Milton, Byron – they’ll exist only in Newspeak versions, not merely changed into something different, but actually changed into something contradictory of what they used to be. Even the literature of the Party will change. Even the slogans will change. How could you have a slogan like “freedom is slavery” when the concept of freedom has been abolished? The whole climate will be different. In fact there will be no thought as we understand it now. Orthodoxy means not thinking – not needing to think. Orthodoxy is unconsciousness." (54) 

Duckspeak is a form of Newspeak language in which the Party continuously changes its position on issues, or simple facts, and treats the practice as normal and good as long as it's in keeping with Party orthodoxy. Party leaders must speak without thinking and the audience must listen without thinking and take pride in doing so. The purpose of this is to disengage the mind from the ability to think critically and thereby unquestioningly accept contradictory instructions and statements, as well as an ever-changing world view, based soley upon the authority of the Party leadership.

Failure to adopt this mindset is characterized as "thoughtcrime," or "crimethink" which Rachel Maddow is guilty of commiting in this video by pointing out the contradictory statements of the Republican Party. At the end of the video she is publicly denounced at CPAC for doing this very thing. Interestingly, the right-wing reactionary who denounces her wishes that she was never born, something Orwell covers in his novel by describing how thought criminals were erased not only physically but historically, with all traces of their existence being eliminated as if they'd never been born.

"The word free still existed in Newspeak, but it could only be used in such statements as “This dog is free from lice” or “This field is free from weeds.” It could not be used in its old sense of “politically free” or “intellectually free,” since political and intellectual freedom no longer existed even as concepts, and were therefore of necessity nameless."
