What happens
Coriolanus refuses to apologize to the tribunes, insisting his nature cannot be changed. Volumnia and Menenius urge him to perform humility and control his anger for Rome's sake. After fierce resistance, Coriolanus agrees to return to the marketplace and use flattery, though he despises the performance. He departs, reluctantly accepting what he calls a role he has never played.
Why it matters
This scene crystallizes the play's central conflict: the impossibility of forcing Coriolanus to become someone he is not. Volumnia argues that controlling one's nature in politics is no different than adapting tactics in war—a reasonable appeal to a military man. But Coriolanus sees performance as dishonor, a betrayal of truth itself. His declaration 'I cannot / bring / My tongue to such a pace' is not mere stubbornness; it reflects a genuine gap between his nature (direct, violent, contemptuous) and what politics requires (calculated speech, false humility, flattery). Volumnia's wisdom is real—she understands survival—yet it asks him to commit what he experiences as a kind of self-annihilation.
What emerges is not compromise but capitulation wrapped in performance. Coriolanus agrees to 'mountebank their loves' and 'come home beloved,' but his language reveals the cost: he must 'possess me some harlot's spirit' and teach his mind 'a most inherent baseness.' He goes not because he is convinced but because his mother demands it, and he loves her more than he loves his own integrity. This submission to maternal pressure, disguised as political necessity, is the tragedy in miniature. He will go to the marketplace and lie, but the play has shown us that this performance will fail—not because he cannot execute it, but because something in him will betray it. His nature, as Menenius later observes, is 'too noble for the world.'
