CASSIUS
I did not think you could have been so angry.
BRUTUS
O Cassius, I am sick of many griefs.
CASSIUS
Of your philosophy you make no use
If you give place to accidental evils.
BRUTUS
No man bears sorrow better. Portia is dead. (4.3.164-168)
Brutus exercises another type of humility here: stoicism, or the realization that life is a burden that each man has to bear. He figures he might as well bear suffering nobly rather than getting worked up over every little thing, like his wife dying or murdering his best friend.
