Aristotle: Poetics, Tragedy and Catharsis Explained for English Literature Exams

Which Greek philosopher called poetry an imitation of an imitation, two steps away from the truth? Students write “Aristotle” for this every year, and every year it is wrong. It was Plato, in Book X of the Republic. Aristotle, his pupil for about twenty years, wrote the Poetics partly as a reply: imitation is natural to human beings, we learn through it, and a well-made tragedy does something useful with the emotions Plato wanted to keep out of the city.

The site’s own literary criticism question set puts this exact trap to students, with Aristotle sitting as option 1 and Plato as the answer. Another item from the same set asks you to judge two statements on how Aristotle differs from Plato. If you can keep the two philosophers apart, a good third of the classical criticism questions become easy marks.

Why examiners keep coming back to the Poetics

The Poetics is short, about 26 chapters in modern editions, and it reads like lecture notes because it probably was one. That makes it easy to set questions on. Almost every phrase in the definition of tragedy has turned into a question at some point: which chapter, which six parts, which emotions, what “magnitude” means.

There is a second reason. Every later critic in the syllabus argues with Aristotle. Horace adapts him, Sidney and Dryden quote him, Dr Johnson defends Shakespeare against rules that were blamed on him, and Arthur Miller writes against him in 1949. So Aristotle appears in questions that are nominally about someone else. In the site’s papers he turns up in match-the-following lists, chronology items and statement-pair questions, far more often than in direct “who wrote” items.

My advice on priorities: learn chapters 1 to 15 properly and know the gist of chapters 23 to 26 on epic. You do not need the long sections on diction and grammar (roughly chapters 19 to 22) beyond knowing they exist.

The texts and the dates that get asked

Ancient dates are approximate, and you will see slightly different years in different books. The later dates trace how the Poetics reached English criticism, which is where several chronology questions come from.

The concepts, one at a time

Each concept below gives the term, what Aristotle means by it, where it sits in the Poetics, and a one-line example. Chapter numbers follow the standard modern division.

Mimesis (imitation): chapters 1 to 4

All poetry, music and dance are forms of imitation. Aristotle sorts them by three things: the medium (rhythm, language, melody), the objects (people better than us, worse, or the same) and the manner (narrating or acting out). In chapter 4 he gives two natural causes of poetry: the human instinct to imitate, from which we learn our first lessons, and the pleasure we take in imitations, even of things that are painful to look at in life. Example: we enjoy a precise picture of a corpse that we would not want to see in reality.

This is the core of his answer to Plato. For Plato, imitation copies a copy. For Aristotle, imitation is a way of knowing.

The definition of tragedy: chapter 6

In Butcher’s 1895 translation: “Tragedy, then, is an imitation of an action that is serious, complete, and of a certain magnitude; in language embellished with each kind of artistic ornament… in the form of action, not of narrative; through pity and fear effecting the proper purgation of these emotions.” Learn the four building blocks: serious action, complete, of a certain magnitude, and the effect through pity and fear. The word catharsis appears here, in chapter 6, which is a direct question on the site.

The six parts of tragedy: chapter 6

In Aristotle’s order of importance: plot (mythos), character (ethos), thought (dianoia), diction (lexis), song (melos) and spectacle (opsis). Plot is “the first principle, and, as it were, the soul of a tragedy.” Spectacle comes last because it depends more on the stage designer than on the poet. Example: a tragedy can work without much character study, Aristotle says, but not without a plot.

Plot structure: chapters 7 to 11

A whole “has a beginning, a middle, and an end” (chapter 7). It needs a magnitude that the memory can hold at once. Unity of plot does not come from having one hero (chapter 8): a life of Heracles contains many unconnected actions. Plots are simple or complex (chapter 10); a complex plot contains peripeteia (reversal of the situation) and anagnorisis (recognition, a change from ignorance to knowledge). The third part of plot is pathos, the scene of suffering. Example: in Oedipus the King the messenger who comes to cheer Oedipus produces the reversal, and recognition arrives at the same moment, which Aristotle calls the finest kind.

Probability, necessity and history: chapter 9

The poet tells not what has happened but what may happen, according to probability or necessity. Hence “Poetry, therefore, is a more philosophical and a higher thing than history: for poetry tends to express the universal, history the particular.” Example: Sidney borrows this argument in An Apology for Poetry when he sets the poet above the historian.

Hamartia and the tragic hero: chapter 13

The best tragedy shows a change from good fortune to bad. The hero should be neither a villain nor a perfectly good man, but someone in between, who falls through some hamartia, an error or mistake of judgement, rather than through vice. Aristotle’s examples are Oedipus and Thyestes. A good man falling for no reason is shocking, not tragic; a villain falling satisfies our moral sense but stirs neither pity nor fear.

Character: chapter 15

Four aims: characters should be good, appropriate (true to type), like (true to life) and consistent, even if consistently inconsistent. The same chapter says the unravelling should come out of the plot itself, not from the deus ex machina. Example: Aristotle objects to the dragon chariot that rescues Medea.

Catharsis

Aristotle never explains the word in the surviving Poetics. That gap produced three main readings: purgation (a medical release of excess pity and fear), purification (a moral refining of those emotions) and clarification (an intellectual understanding of them). Examiners usually want “purgation” when the options give only one, and the site’s PYQ phrases the idea as a “safe outlet” for intense emotions.

Tragedy, epic and comedy: chapters 5 and 26

Comedy imitates people worse than average, and the ludicrous is a kind of the ugly that causes no pain. Tragedy tries to stay “within a single revolution of the sun, or but slightly to exceed this limit”; epic has no fixed time. In chapter 26 Aristotle ranks tragedy above epic, because it reaches its effect in a shorter space and with more unity.

Who said it: quotation table

These lines are the usual raw material for “identify the critic” items. The trick is that Plato and Horace sit right next to Aristotle in the options.

Asked in exams: real questions from the site

Every row below is taken from a previous year question page on this site. Where the page shows the paper and year, it is given; the two literary criticism sets mark their items as previous year questions without listing each paper. For more, see the topic-wise previous year questions and the full question paper archive.

Look at the pattern. Only two of these eleven ask “who wrote the Poetics” in any form. The rest test whether you know the text from inside: chapter numbers, the order of ideas, and the line between Aristotle and his neighbours. The chronology item from June 2025 is the clearest sign of where questions are heading. For extra practice on the same ground, try the Plato and Aristotle MCQs.

Afterlife: how Aristotle reached English criticism

The Poetics was nearly lost to Western Europe for centuries. It came back first through an Arabic commentary by Averroes, put into Latin in 1256, then through Valla’s Latin translation (1498) and the printed Greek text (1508). Italian Renaissance commentators then turned it into a rulebook.

• Castelvetro (1570) fixed the three unities of action, time and place. Aristotle insists only on unity of action; he notes the one-day habit of tragedy and never mentions unity of place.
• Sidney, in An Apology for Poetry, uses Aristotle to defend poetry and attacks English plays that mix kings and clowns.
• Milton opens Samson Agonistes (1671) with a preface citing Aristotle on pity, fear and purging the mind.
• Dryden‘s An Essay of Dramatic Poesy (1668) stages a debate on whether the French, who keep the unities, beat the English, who do not.
• Dr Johnson‘s Preface to Shakespeare (1765) throws out the unities of time and place and keeps only action. The site has asked this.
• Arthur Miller‘s essay “Tragedy and the Common Man” (1949) argues that an ordinary man can be a tragic hero, against the high-born hero of Greek tragedy. See the Arthur Miller guide for Willy Loman.

If you are also preparing the Renaissance and Victorian critics, the Matthew Arnold guide shows the same habit of going back to the Greeks, and the Shakespeare guide covers the plays the unities debate was fought over.

Firsts, and one thing he did not do

A few “credited with” points come up in statement questions. Use the safe wording below.

• The Poetics is the earliest surviving work in the West devoted to the theory of poetry as an art.
• It gives the earliest surviving formal definition of tragedy.
• It is the source of the terms peripeteia, anagnorisis and hamartia as critical terms, and of the plot-first ranking of the six parts.
• Not Aristotle: the three unities as a rule. That is Renaissance work, chiefly Castelvetro’s.

FAQ

For the full text in English, Butcher’s translation is the one most textbooks quote; for life dates, see Britannica’s summary of Aristotle.

What should I study first in Aristotle’s Poetics for exams?

Chapter 6 (the definition of tragedy and its six parts), chapters 7 to 11 on plot, chapter 9 on poetry and history, and chapter 13 on the tragic hero and hamartia. These carry most of the questions.

What is the difference between Plato and Aristotle on poetry?

Plato, in Republic Book X, calls poetry an imitation of an imitation that feeds the emotions. Aristotle treats imitation as natural and instructive, and argues that tragedy uses pity and fear to bring about catharsis.

Did Aristotle invent the three unities?

No. He requires unity of action and notes that tragedy tends to keep within one day. The three unities as a fixed rule come from Renaissance critics, chiefly Castelvetro in 1570.

What does catharsis mean?

Aristotle does not define it in the surviving Poetics. The main readings are purgation, purification and clarification of pity and fear. Exams usually accept purgation.
