It gives a test for whether a story holds together: each incident should seem to grow from what came before.
A complete work has a beginning, middle, and end, and a size that can be embraced in a single view or held in memory.
It offers a standard for unity and length, treating a work like an organism whose parts must be ordered and proportioned.
Poetry shows how a certain type of person would probably or necessarily speak or act, rather than recording specific facts.
It clarifies what fiction is for: to reveal general truths of human action rather than to report what merely happened.
Summary
Poetics is a working analysis of how poetry is made and why it affects us. Aristotle begins from a single idea: epic, tragedy, comedy, dithyramb, and instrumental music are all forms of imitation. They differ in the medium they use, the objects they represent, and the manner in which they represent them. This framework lets him classify the arts and then concentrate on tragedy.
His definition of tragedy is the center of the work. Tragedy is the imitation of an action that is serious, complete, and of a certain magnitude, presented in heightened language, performed rather than narrated, and working through pity and fear to bring about the purgation of those emotions. From this definition he derives the six parts of tragedy: plot, character, thought, diction, song, and spectacle.
Aristotle ranks these parts. The structure of the incidents, the plot, is the first principle and the soul of the tragedy, because tragedy imitates action and life rather than men in the abstract. Character holds second place, thought third, and spectacle least, since the power of tragedy can be felt even apart from performance. This ordering is the book's most influential claim about dramatic art.
He then sets out what makes a plot good. It must form a whole with a beginning, a middle, and an end, where each part follows by causal necessity rather than chance. The most powerful effects, reversal of fortune and recognition, belong to the plot itself. The best tragic plot turns a person who is neither wholly good nor wicked from prosperity to misfortune through some great error or frailty rather than through vice.
Across the work Aristotle distinguishes poetry from history. The poet relates not what has happened but what may happen according to probability or necessity, which is why poetry tends toward the universal while history records the particular. He extends the same standards of unity, magnitude, and probability to epic, and closes by comparing epic and tragedy and judging tragedy the higher form.

Selected Quotes
The Plot, then, is the first principle, and, as it were, the soul of a tragedy: Character holds the second place.
Poetry, therefore, is a more philosophical and a higher thing than history: for poetry tends to express the universal, history the particular.
whose misfortune is brought about not by vice or depravity, but by some error or frailty.
