I think the premise of total control through language is in itself silly, though that can be excused by the book being satire. But Orwell, for good or ill, was undeniably a linguistic purist, as one can gather from a close reading of "Politics and the English Language".

I said earlier that the decadence of our language is probably curable. Those who deny this would argue, if they produced an argument at all, that language merely reflects existing social conditions, and that we cannot influence its development by any direct tinkering with words and constructions. So far as the general tone or spirit of a language goes, this may be true, but it is not true in detail. Silly words and expressions have often disappeared, not through any evolutionary process but owing to the conscious action of a minority. Two recent examples were explore every avenue and leave no stone unturned, which were killed by the jeers of a few journalists. There is a long list of fly-blown metaphors which could similarly be got rid of if enough people would interest themselves in the job; and it should also be possible to laugh the not un- formation out of existence, to reduce the amount of Latin and Greek in the average sentence, to drive out foreign phrases and strayed scientific words, and, in general, to make pretentiousness unfashionable.
