When President Bush delivers his State of the Union message, he's expected to emphasize the ideals of freedom and liberty, as he did in his Inaugural address. But what does freedom mean today -- and what did it used to mean?
We look at two perspectives on President Bush's use of the word "freedom" -- and we talk with an American historian who has investigated how the use of "freedom" and "liberty" has changed and evolved since our country's earliest days.
