I've been reading Richard Wilbur lately, but that's not exactly the opposite I was thinking of. In The Practice of Poetry: Writing Exercises From Poets Who Teach, Stuart Dischell writes about The Attraction of Titles.
(1) Choose a pair of words with opposite or nearly opposite meanings. Primary choices such as "hot and cold" or "good and evil" might be avoided, although sometimes the obvious can be a good place to begin. Try instead to find a more suggestive or playful pairing such as "calm and calamity." (2) Write a poem titled and based upon the word you have chosen.So, that's it. Your challenge is to write a poem that uses opposites in poem and title. Leave me a comment about your piece and I'll post the results here later this week.
