How we cite our quotes:
I did not think you could have been so angry.
O Cassius, I am sick of many griefs.
Of your philosophy you make no use,
If you give place to accidental evils.
No man bears sorrow better. Portia is dead. (4.3.30)
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.
