This study is concerned with the dramaturgic use of the fools of five of Shakespeare's plays. After the Introduction, Chapter II investigates the fool as a historical figure and establishes his credibility. Chapter III examines the comic methods and techniques of the fools. Chapter IV is an investigation of the use of the fool in his capacity as choric voice to present a particular viewpoint on the play. Chapter V is a study of how the fool fits into the action as a character, and Chapter VI investigates the ways in which he may be used in structural duties. The study concludes that the Shakespearean fool is an effective device due to his historical credibility and his recognized position as an entertainer.
