Newspeak

The language of Oceania from 1984. It's stated purpose is to eliminate non oceanic thought. Basically if you remove a word like freedom from the language and include it's synonyms, there won't be a word to describe that particular concept and therefor it will be that much more difficult to formulate. Even more difficult would be conveying the concept to someone else. In relation to modern society we can also draw upon the similarity of redefining such concepts. Take the quote, "they hate us because we're free" and look at some of the direct outcomes from that statement the USA patriot act for example. Something that truly does directly limit our freedoms.
