"believe me for mine honour, and have respect to mine honour..." (3. 2 61). This line establishes Brutus's credibility because he is saying that he is honorable.
"Had you rather Caesar were living and die all slaves, than that Caesar were dead, to live all free men?" (3.2 61). This appeals to the citizens emotion by predicting that the people would be slaves to Caesar if he was alive.
"...as he was ambitious, I slew him" (3.2 61). This shows logos because it is Brutus's truth. He killed Caesar for his ambition.
