"Believe me for mine honour, and have respect to mine honour, that you may believe; censure me in your wisdom, and awake your sense, that you may better the truth." (2.2.61.) This represents credibility because it shows what Brutus believes in.
"As Caesar loved me, I weep for him; as he was fortunate, I rejoice at it;" (2.2.61). This mode of persuasion was present because it shows Brutus using emotion such as, "I weep for him." "There is tears for his love; joy for his fortune; honour for his valour; and death for his ambition. (2.2.61)
"Not that I loved Caesar less, but that I loved Rome more."(2.2.61) This shows pathos because it is Brutus explaining exactly his views.
