"Bergman’s procedure, with the beginning and end of Persona and with this terrifying caesura in the middle, is more complex than the Brechtian strategy of alienating the audience by supplying continual reminders that what they are watching is theatre (i.e., artifice rather than reality). Rather, It is a statement about the complexity of what can be seen and the way in which, in the end, the deep, unflinching knowledge of anything is destructive. To know (perceive) something intensely is eventually to consume what is known, to use it up, to be forced to move on to other things."
