How can you really narrow the range of thought by narrowing vocabulary, as the Party seeks to do? and are there any counterexamples to the Party’s proposition?

Hey, your earlier questions were way too long. This is why they are not gtting through. You need to shorten them. The party knew that narrowing range of thought would not happen instantly. The narrowing of expression would happen over generations through, among other things, the shortening of language. People would gradually lose the words to express themselves and over generations would cease to express themselves. That was the idea. As to your other query, I suppose if we believe in the inherent human need to express themselves, they would find other ways besides language to do this.
