 Incidentally this argument turns on an assumption that Plato asserts without discussion, that mimêsis is the presentation or representation of characters (e.g. 603c; 605a, c). Although Book 10 sometimes speaks of mimêsis in other terms (mimêsis of virtues: 600e), the argument about fostering passions requires that objects of poetic representation be humans. When what we call literary works practice what we call representation, Plato claims that they represent human beings. For him as for Aristotle drama presents prattontas “people doing things,” but where Aristotle emphasizes the things done, for Plato it is the people. Character is the essence of epic and drama. (Halliwell 1988 argues otherwise.)
