All 26 chapters — from the definition of mimesis to the verdict on tragedy versus epic.
The Poetics divides into three main movements. Chapters 1–5 define imitation and survey its kinds. Chapter 6 gives the gravitational definition of tragedy; chapters 7–18 unpack its parts — plot at greatest length, then character, thought, diction. Chapters 19–22 cover language and style. Chapters 23–26 turn to epic and close with the comparison. The book is short enough to read in a single sitting and rewards continuous attention.
Poetry as imitation. The arts compared. The origins of tragedy and comedy.
The foundational claim: all the arts are modes of imitation, differing in medium, object, and manner. Aristotle surveys flute, lyre, dance, and poetry to establish the framework the rest of the treatise builds on.
The objects of imitation are always people in action — but of higher or lower moral type. Tragedy imitates the better; comedy the worse. A two-paragraph chapter that establishes the axis everything else runs on.
The third dimension of difference: narrative versus dramatic manner. Homer narrates; Sophocles presents characters directly in action. Three paragraphs closing the introductory taxonomy before the history of poetry begins.
Two instincts — imitation and harmony — gave rise to all poetry. Aristotle traces the historical development from improvisation to Homer, from Homer to the split between comedy and tragedy, and from the dithyramb to Aeschylus and Sophocles.
Comedy imitates inferior but non-wicked types; the ludicrous is the painless ugly. Epic agrees with tragedy in elevated characters but differs in meter and length. The ground cleared for the definition to follow.
The six parts of tragedy. Plot as the soul.
The famous definition: tragedy is the imitation of a serious, complete action of a certain magnitude, accomplishing through pity and fear the catharsis of such emotions. Six parts follow, in order: plot, character, thought, diction, song, spectacle. Plot is the soul.
Magnitude, unity, reversal, recognition, hamartia, pity and fear.
A plot must be a complete whole with beginning, middle, and end — and of a certain magnitude: not so small it cannot be perceived, not so large it cannot be grasped as a whole. The chapter defines the structural logic of tragic action.
One paragraph, a single correction: unity of plot is not unity of hero. Homer told not the life of Achilles but one action within it. Remove or rearrange any part of a unified plot and the whole is damaged.
Poetry is more philosophical than history because it tells not what happened but what could happen — the universal rather than the particular. The worst plots are episodic; the best produce surprise through causal necessity.
Plots are either simple — continuous change without reversal or recognition — or complex, where the change is accompanied by reversal, recognition, or both. Both must arise from the internal structure of the plot. The complex is the higher kind.
Reversal: the action veers to its opposite. Recognition: ignorance gives way to knowledge. In Oedipus both happen in the same scene. A third element, the scene of suffering, involves destructive or painful action. These are the technical heart of the treatise.
The quantitative parts of a tragedy: prologue, parode, episode, stasimon, exode, and (sometimes) kommos. A technical anatomy of the formal structure of Greek drama.
The tragic protagonist must be intermediate — not wholly good, not wicked — falling through hamartia (error or misjudgment) rather than vice. A good person falling merely revolts; a wicked person falling merely satisfies. Oedipus is the model.
Pity and fear produced from the plot itself are better than those produced by spectacle. The worst deeds involve enemies harming enemies; the best involve bonds of friendship or kinship. Ignorance followed by discovery is the highest form.
What character must be. Forms of recognition. How to build a plot.
Four rules for tragic character: good, appropriate to type, realistic, consistent. Character, like plot, must follow necessity or probability. The deus ex machina is a failure of construction. Sophocles drew men as they ought to be.
Six forms of recognition, from recognition by tokens (least artistic) to recognition arising from the incidents themselves (best). The hierarchy is clear: the closer recognition is to plot necessity, the more truly it belongs to the art of tragedy.
Three practical rules: visualise the scene before writing; work with gesture as you compose; sketch the general outline before filling in episodes. Aristotle illustrates how a complex plot can be reduced to a brief general statement, then expanded.
Every tragedy has complication and unraveling. Four kinds of tragedy: complex, pathetic, ethical, spectacular. A tragedy should not have epic multiplicity of plots. The Chorus should be integral to the action — an actor, not a musical interpolation.
Thought, diction, the parts of language, and the command of metaphor.
Two paragraphs pointing toward what remains. Thought (the ability to say what is pertinent and possible in given circumstances) is covered by rhetoric. Diction (the expression of meaning in words) is covered by the next three chapters.
The elements of language from letter to sentence: letter, syllable, connecting word, noun, verb, inflexion, sentence. The most granular and grammatical chapter in the treatise.
The taxonomy of poetic words: current, strange, metaphorical, coined, lengthened, contracted, altered. Metaphor receives the fullest treatment — the application of an alien name by transference, including the proportional metaphor A:B::C:D.
Clear without being mean: the standard for poetic diction. Strange words, metaphors, and compound words provide elevation; current words provide clarity. The command of metaphor is the mark of genius and cannot be taught.
Epic structure, epic versus tragedy, the final ranking.
Epic must have a single action — whole, complete, unified — not the whole Trojan War but one action within it. Homer grasped this; other epic poets have not. A one-paragraph statement of the most important principle for epic construction.
Epic's special capacity: simultaneous actions and more room for the wonderful. Homer alone understood the epic poet's proper role — minimal first-person narration, maximal dramatic imitation. The heroic meter is the only suitable one.
Five sources of critical objection to poetry — the impossible, the irrational, the morally harmful, the contradictory, the inartistic — and their appropriate defences. The longest chapter in the Poetics; a practical manual for reading difficult passages.
The final verdict: tragedy is the superior form. It has all the elements of epic plus music and spectacle; it is more unified and concentrated; and it achieves its proper pleasure more fully than epic can. The Poetics closes.
