Analyse de Roméo et Juliette : métaphore et identité

Read the following famous lines from Act $2$, Scene $2$: 'What's in a name? That which we call a rose / By any other name would smell as sweet; / So Romeo would, were he not Romeo call'd, / Retain that dear perfection which he owes / Without that title.'

Task: Analyze how Juliet uses this botanical metaphor to challenge the social constraints of Verona. Discuss the conflict between personal identity, represented by the variable $I$, and the social obligation of the family name, represented by the variable $F$. Explain how the tension between $I$ and $F$ drives the tragic arc of the play.
