Rather than being overwhelmed with emotion by her death, Brutus controls his emotions in typical stoic fashion and continues planning his military strategy against Octavius.

When informed of Portia's suicide (who killed herself by swallowing hot coals), Brutus reacts in a very measured, controlled way. He is not overwhelmed with emotion.

This is a response typical of the philosophical ideas of stoicism.
