Scene-by-Scene Overview

Act 3 begins with the famous 'To be, or not to be' soliloquy, where Hamlet contemplates the nature of existence and the fear of the unknown. This is followed by the intense 'nunnery' scene with Ophelia, which highlights Hamlet's growing disillusionment. In Scene 2, the 'play-within-a-play' succeeds in provoking King Claudius, providing the 'proof' Hamlet sought. Scene 3 shows Hamlet passing up a chance to kill Claudius while he is praying, fearing he would send his uncle's soul to heaven. Finally, Scene 4 concludes with the confrontation between Hamlet and Gertrude, resulting in the accidental death of Polonius.

Key Themes: Action vs. Inaction

The central theme of Act 3 is the struggle between thought and action. While students often compare these notes to summaries found on sites like SparkNotes, it is essential to focus on why Hamlet hesitates. His decision not to kill Claudius during prayer is a pivotal moment of inaction that leads to the tragic deaths in the final acts. This act demonstrates that while Hamlet is intellectually ready for revenge, his moral and spiritual concerns create a paralyzing delay.

Analysis of the Closet Scene

The confrontation in Gertrude’s private chamber is a turning point. Hamlet’s aggressive behavior toward his mother reveals his deep-seated resentment regarding her marriage. The sudden death of Polonius, whom Hamlet kills while he is hiding behind the tapestry, marks Hamlet's transition from a victim of circumstances to an active perpetrator of violence. This shift is critical for any essay regarding Hamlet’s character arc and the inevitability of the play’s tragic ending.

Study Tips for Exams and Essays

To prepare for a quiz or class discussion, focus on the dramatic irony in Scene 3: Hamlet thinks Claudius is repenting, but the audience knows Claudius's prayer is unsuccessful. For essays, analyze how the Ghost’s reappearance in Scene 4 serves to redirect Hamlet’s focus. Practice identifying the shift in tone from the philosophical melancholy of the early scenes to the frantic, bloody action at the end of the act.

Why does Hamlet choose not to kill Claudius in Act 3, Scene 3?

What is the significance of the play 'The Mousetrap'?
