Aristotle considered it important that there be a certain distance between the work of art on the one hand and life on the other; we draw knowledge and consolation from tragedies only because they do not happen to us. Without this distance, tragedy could not give rise to
catharsis. However, it is equally important that the text causes the audience to identify with the characters and the events in the text, and unless this identification occurs, it does not touch us as an audience. Aristotle holds that it is through "simulated representation," mimesis, that we respond to the acting on the stage, which is conveying to us what the characters feel, so that we may
empathise with them in this way through the mimetic form of dramatic roleplay. It is the task of the dramatist to produce the tragic enactment to accomplish this empathy by means of what is taking place on stage.
In short, catharsis can be achieved only if we see something that is both recognisable and distant. Aristotle argued that literature is more interesting as a means of learning than history, because history deals with specific facts that have happened, and which are contingent, whereas literature, although sometimes based on history, deals with events that could have taken place or ought to have taken place.
