Final answer:
Portia uses pathos, an appeal to emotions, to persuade Brutus to share his secrets with her in Shakespeare's 'Julius Caesar'.
Step-by-step explanation:
In William Shakespeare's play Julius Caesar, Portia uses pathos to convince Brutus to tell her his secrets. When Portia makes her plea, she appeals to Brutus's emotions and sense of duty as her husband.
Pathos is the rhetorical appeal that targets the audience's emotions, trying to inspire feelings like sympathy, love, or guilt, to influence someone's decision or perspective.
In her speech to Brutus, Portia evokes the strength of their marital bond and her loyalty to him, and thereby, she seeks to make him feel morally compelled to confide in her.
