The critic in the audience can’t always help that they may actually conceive of the notes which would make a performance better. It is quite often the case that the critic does not themself possess the ability to make the prudent changes in their own performance. Or, perhaps, to become an expert in public critique is their performance— their true character’s role. It is precisely for this reason why they find their appropriate seat in the auditorium and not on the stage. It is also the reason why one should never allow personal emotions to cause reactions of resentment or hostility toward the critic, but instead applaud them for knowing their own role, and committing to it.
“Theater” is, after all, never just a stage— the presumed singular site of spectacle, but a whole unit, consisting of many dynamic and performative spaces. This holistic unit includes a stage, yes, but at a larger scale, it also includes an auditorium, filled in abundance with viable seats.
