By 2050—earlier, probably—all real knowledge of Oldspeak will have disappeared. 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 of thought 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.
As language devolves?
Just as some people are creating their own languages for use in their own social circles, I too am now creating my own language to reflect how I perceive what others are saying, regardless of what they actually mean by their words.
From now on, anyone telling me to speak or behave according to their definitions will be perceived by me to be threatening me and insulting me, and should immediately begin self-flagellation actions so that they might become better human beings in my eyes.
