What is Cassius suggesting and how does he build his argument?

Cassius believes Caesar is not capable of ruling Rome. He believes Brutus would be a much better leader than a man who is weak and inferior. Cassius asks if Brutus sees himself as a person, but he says he cannot, to which Cassius replies, “That you have no such mirrors as will turn/ Your hidden worthiness into your eye” (I ii 56-57). He tells Brutus that he will be his personal mirror so that he can see what kind of a man he is. Cassius says that the people of Rome believe Brutus is worthy and honorable, but it is just him that does not believe so. He tries to build up his argument and convince Brutus he is capable of being a leader, by comparing themselves to Caesar. He says, “I had as life not be, as live to be/ In awe of such a thing as I myself” (I ii 95-96). Cassius says that he “was born free as Caesar; so were you:/ We both have fed as well, and we can both/ Endure the winter’s cold as well as he” (I ii 97-99). He believes even he himself and Brutus are the same as Caesar, there is nothing special about this man. If Caesar was so amazing, he would be different from everyone else. Cassius builds up his argument by telling the stories of the times where Caesar was weak and vulnerable, and that rulers should not be like this. He tells the story of when Caesar was swimming in Tiber River and he was too weak and started sinking as he cried for help. He does not understand how he can save Caesar, who is weak, but now he has become a god in the eyes of others. And the other time when Caesar had a fever in Spain, he started to shake. Cassius questions if god’s shake or even manage to get sick with sickness commoners get. Cassius adds on by saying, “Men at some time are masters of their fates:/ The fault, dear Brustus, is not in our stars,/ But in ourselves” (I ii 139-142). He believes men should decide their fate and take action. He then questions what the difference is with the names Brutus and Casear. “What should be in that “Caesar”?. Why should that name be sounded more than yours?” He compares the names constantly as he adds in the word “as” to everything Brutus and Caesar have equally. Cassius is able to sway his thoughts and consider what he is saying.
