In Julius Caesar, How are the characters more impacted or motivated by actions and not words? The play is known for it's rhetorical influence, but actions have more influence on the characters. Brutus is one of the characters that is driven by actions.
Marc Antony is, indeed, more effective with the plebians because of his actions. The uncovering of Caesar's body, as so cogently mentioned above, is extremely effective. Combined with his producing of Caesar's will, Antony ignites a civil war.
Portia's suicide that is not mentioned by Brutus indicates the fatal direction he heads along with his ignoring of Cassius's counsel to remain in Sardis and not march to Philippi.
This question becomes a little more complex when you think about Antony's "honorable men" speech. Yes, it's a rhetorical masterpiece, and the simple Roman citizens are no match for his powers of persuasion. But, what does Antony do at the very beginning of his speech? He uncovers Caesar's body for the people to see--this is an action.
Brutus did not speak loudly enough with his actions in that he allowed Antony to live. Brutus should have listened to Cassius and killed Antony. Antony destroyed Brutus with his rhetoric. Clearly, Antony and his speech made Brutus's actions not as effective.
I would have to agree with the third post here and suggest that the rhetorical power of Antony's speech is more compelling and effective than any action. The murder of Caesar does not seem to have riled up the mob nearly as much as the speech Antony gave to characterize the men behind the murder.
In a way, the play is a good example of the power of words versus actions. Caesar and Antony use words, Brutus and company use actions. It should be noted that Brutus also uses words to trick Caesar into thinking he is a loyal friend. Ultimately, I suppose actions win out in terms of Caesar’s assassination, but Antony fights back with his speech about “honorable men” for sure!
Of course, Brutus is the leader of the action that the entire play revolves around, i.e. the assassination of Caesar. So in a way, he and his co-conspirators used action, not words, to rescue the Republic, in their own minds. But on the other hand, I do think Shakespeare is more interested in the power of rhetoric to move the masses, as the example of Antony's speech clearly shows.
