How does Shakespeare explore the theme of love throughout the play?I need quotes from the play and I have to analyze it so could you please give me guidance on how to write the essay?
As with nearly all Shakespearean comedies, one of the main themes of Much Ado About Nothing is love and can be explored on many levels. There is familial love--such as that between Beatrice & Hero, Hero & Leonato, and Antonio & Hero. The best way to explore the theme from this perspective is to look at quotes after scene 1 of Act IV--the reactions of the characters to the accusal of Hero.
Romantic love is also thoroughly explored throughout the play. The most obvious is between Benedick and Beatrice. As the play's two dynamic characters, they both exclaim to never love or marry in the beginning, but characteristically fall in love and pledge faithfulness by the end of the play. At the very end of the play, the love of these two characters is best noted through the sonnets they attempt to write for one another. Shakespeare jokes about writing in the sonnet writing, for many of his sonnets pertain to love--he is claiming that the pen and heart are one entity even while the tongue opposes. The second most obvious is Claudio and Hero, though their love goes through obvious tribulations, as Claudio's name means "lame," he is often easily persuaded to believe the worst in others.
Finally, you can explore the love of "brothers." You could explore the beginning of Act V, when Leonato and Antonio discuss family life and how Antonio will challenge Claudio to the duel because Leonato is too old. You could also explore how Don Pedro will woo Hero for Claudio in Act II, and how Don Pedro stands by Claudio's side when Claudio decides to shame Hero publically in Act IV.
