I use this powerpoint in my class (along with a preprinted handout for notes) to begin a British literary unit on early Modern English and/or John Donne and/or Sonnets. It's a good preface for complicated characters (like those in Macbeth, for example) which need to analyzed based on an understanding on contradicting and paradoxical behavior. It contains the difference between contractions and paradoxes, examples of each, a dissectable copy of "Batter my Heart" by John Donne, usable quotes for journals and the like about contraction, and the linking of these observations pertaining specifically to literature. It's a good lesson because it bridges the gap between real life and whatever text you're introducing. This way, your students can not only learn about characters but themselves.
