Comedy and Tragedy--Collected here in one binding are All's Well That Ends Well Measure for Measure and The History of Troilus and Cressida. Collectively they are known as Shakespeare's Problem Plays. While the first two are usually placed with the comedies and the later with the tragedies none of them fit neatly into either classification. Their structure subject matter and resolutions create problems for those who want simple classifications. The term was coined by critic F. S. Boas who believed that these plays each explored a moral dilemma and social problem through their main characters giving the term a layered meaning. O it is excellentTo have a giant's strength;But it is tyrannousTo use it like a giant.
