This is a quite relevant short essay by George Orwell, the author of 1984. We are now at the point in our political degeneration where words are literally being redefined in an attempt to manipulate the perception of reality itself. Our thoughts are composed of words, therefore our world views are dependent on their definitions. 1984 was not supposed to be a manual, but unfortunately he was even more prophetic than most people ever imagined. Just don't forget, 2 + 2 = 5. Your life may soon depend on it.
