In Poetics chapter 9, Aristotle famously claims that poetry is more philosophical than history. What does this mean? I argue that he is talking about the metaphysics of events. Poets seek causal coherence among the events in their stories. Historians must report what happened whether or not the events of history exhibit causal coherence. This makes the poet's job more philosophical than the historian's, for the poet is seeking a unified plot -- an action-type -- that serves as the backbone (...) of the story he is trying to tell. The poet's final script is a token of an Aristotelian universal, the universal being an action-type that could have been fleshed out in many different ways, although with similar characters. Hence, the poet shows us what he thinks it is likely or necessary for agents of different types to do in the circumstances that confront them. Aristotelian mimesis, on this account, is the poetic representation of "one action," that is, of one action-type. (shrink)
