" It means the story of the play, its facts, events, epoch, time and place of action, conditions of life, the actors’ and regisseur’s interpretation, the mise-en-scene, the production, the sets, the costumes, properties, lighting and sound effects,—all the circumstances that are given to an actor to take into account as he creates his role. ‘If is the starting point, the given circumstances, the development. The one cannot exist without the other, if it is to possess a necessary stimulating quality. However, their functions differ somewhat: if gives the push to dormant imagination, whereas the given circumstances build the basis for if itself. And they both, together and separately, help to create an inner stimulus. "

― Konstantin Stanislavski , An Actor Prepares
