Like many a great speaker, Marc Antony does not overestimate his audience. He speaks to the crowd, rather than above it as Brutus does in his lofty speech of honor and other abstract ideas. Antony appeals to the baser desires of the plebeians such as greed and envy.
In addition, Antony manipulates words better, making use of several rhetorical devices. such as repetition and the use of emotional words.
The "proof is in the putting" in this case. Antony's speech was the one that created its desired outcome. Brutus' speech was well-received but did not achieve its aims.
I agree with the above post. Antony's speech was more effective. He did have the last word which offered him the opportunity to recap on Brutus's comments. His use of rhetoric outweighed Brutus's use of rhetoric. Antony played up Brutus's use of honorable. In the end, Antony's speech stirred up the people until they were determined to kill Brutus and his conspirators. Brutus should have listened to Cassius and killed Antony as well.
Antony's was more effective, partly because he went after Brutus, and was able to have the last word, if you will. But it was also because he knew the right buttons to push. He appealed to the emotions of the crowd in a very provocative way that made Brutus's appeals to virtue and to duty ring hollow.
Most people would say Mark Antony's speech was more effective. And it was. But what people fail to mention is that Brutus' speech was equally great.
Brutus might come off as a traitor, and he is, but he had a point to prove. He killed Julius Caesar for the sake of Rome, as he put it. And his speech was effective as he stirred up a commotion among the people. But the reason that Marc Antony's speech is branded most effective is because while Brutus called on people's logic, Marc Antony played with the crowd's feelings and emotion.
His speech had a greater effect as the human mind is most often dominated by the heart, and the logic is killed.
In my opinion, while Antony sought Justice, he also didn't play fair.
It's as the saying goes "Listen to your mind. Your heart is stupid." And that is exactly what the people of Rome failed to do.
Antony is able to mobilize the mob with his speech.He tries to gain respect and is successful in grabbing the attention of the angry mob.
Antony 's speech is more effectrive as he in the beginning praises those conspirators saying Julius was selfish and their conspiracy was for the good for Romans..
But as he proceeds , he slowly tries to say all the good whatever Julius had done.
Hence People changed their minds.
