What quotes are used to convince and enlarge Brutus' ego?

And be not jealous on me, gentle Brutus.
Were I a common laugher, or did use
To stale with ordinary oaths my love
To every new protester; if you know
That I do fawn on men and hug them hard
And after scandal them, or if you know
That I profess myself in banqueting
To all the rout, then hold me dangerous. (act 1 sc 2)
