Power of words

"The narrative becomes an argument, and argument is designed to exert a compulsive force on the reader, evoking such responses in both writer and reader as "I am forced to think,""I am compelled to accept," and the like"..."A question is thus raised which is implicit in the title of this book: the relation of words to power." (pg 9 of Frye) Words, if written/spoken/expressed in the right way ("The difference between the right word and the wrong word is that between lightening and a lightening bug." Mark Twain) have the power to cause us to change, or at least consider a change in the way we think. After all, Harriet Beecher Stowe's book Uncle Tom's Cabin sparked the Civil War.
