Orwell's Rules

I would say that for the most part that the six solutions for fixing the English language are pretty good, however, I would have to disagree with rule number 5. I believe that sometimes it is okay and acceptable to use a foreign phrase, a scientific word, or a jargon word in a paper. It makes the paper more interesting at times, and there is sometimes a "everyday English equilvalent" that works, but makes the paper more boring.
