Aristotle's work on aesthetics consists of the Poetics, Politics (Bk VIII) and Rhetoric. The Poetics is specifically concerned with drama. At some point, Aristotle's original work was divided in two, each "book" written on a separate roll of papyrus. Only the first part – that which focuses on tragedy and epic (as a quasi-dramatic art, given its definition in Ch 23) – survives. The lost second part addressed comedy. Some scholars speculate that the Tractatus coislinianus summarises the contents of the lost second book. Some other scholars indicate that "tragedy" is a very misleading translation for the Greek tragoidos, which seems to have meant "goat-song" originally. The reason is that Aristotle says three times in the treatise that the protagonist can go from fortune to misfortune or misfortune to fortune; also in Chapter 14 the best type of tragoidos is that which ends happily, like Cresphontes and Iphigenia (presumably "in Tauris")!
The table of contents page of the Poetics found in Modern Library's Basic Works of Aristotle (2001) identifies five basic parts within it.
- A. Preliminary discourse on tragedy, epic poetry, and comedy, as the chief forms of imitative poetry.
- B. Definition of a tragedy, and the rules for its construction. Definition and analysis into qualitative parts.
- C. Rules for the construction of a tragedy: Tragic pleasure, or catharsis experienced by fear and pity should be produced in the spectator. The characters must be four things: good, appropriate, realistic, and consistent. Discovery must occur within the plot. Narratives, stories, structures and poetics overlap. It is important for the poet to visualize all of the scenes when creating the plot. The poet should incorporate complication and dénouement within the story, as well as combine all of the elements of tragedy. The poet must express thought through the characters' words and actions, while paying close attention to diction and how a character's spoken words express a specific idea. Aristotle believed that all of these different elements had to be present in order for the poetry to be well-done. However, starting in 1948 with a Macedonian classicist, M.D. Petruševski, some scholars have rejected that Aristotle himself could have written the word katharsis in the definition of tragedy, because unlike all of the other words in the definition, it is not discussed either before or after the definition.
- D. Possible criticisms of an epic or tragedy, and the answers to them.
- E. Tragedy as artistically superior to epic poetry: Tragedy has everything that the epic has, even the epic meter being admissible. The reality of presentation is felt in the play as read, as well as in the play as acted. The tragic imitation requires less space for the attainment of its end. If it has more concentrated effect, it is more pleasurable than one with a large admixture of time to dilute it. There is less unity in the imitation of the epic poets (plurality of actions) and this is proved by the fact that an epic poem can supply enough material for several tragedies.
Aristotle distinguishes between the genres of "poetry" in three ways:
- language, rhythm, and melody, for Aristotle, make up the matter of poetic creation. Where the epic poem makes use of language alone, the playing of the lyre involves rhythm and melody. Some poetic forms include a blending of all materials; for example, Greek tragic drama included a singing chorus, and so music and language were all part of the performance. These points also convey the standard view. Recent work, though, argues that translating rhuthmos here as "rhythm" is absurd: melody already has its own inherent musical rhythm, and the Greek can mean what Plato says it means in Laws II, 665a: "(the name of) ordered body movement," or dance. This correctly conveys what dramatic musical creation, the topic of the Poetics, in ancient Greece had: music, dance, and language. Also, the musical instrument cited in Ch 1 is not the lyre but the kithara, which was played in the drama while the kithara-player was dancing (in the chorus), even if that meant just walking in an appropriate way. Moreover, epic might have had only literary exponents, but as Plato's Ion and Aristotle's Ch 26 of the Poetics help prove, for Plato and Aristotle at least some epic rhapsodes used all three means of mimesis: language, dance (as pantomimic gesture), and music (if only by chanting the words).
- Also "agents" in some translations. Aristotle differentiates between tragedy and comedy throughout the work by distinguishing between the nature of the human characters that populate either form. Aristotle finds that tragedy treats of serious, important, and virtuous people. Comedy, on the other hand, treats of less virtuous people and focuses on human "weaknesses and foibles". Aristotle introduces here the influential tripartite division of characters in superior (βελτίονας) to the audience, inferior (χείρονας), or at the same level (τοιούτους).
- One may imitate the agents through use of a narrator throughout, or only occasionally (using direct speech in parts and a narrator in parts, as Homer does), or only through direct speech (without a narrator), using actors to speak the lines directly. This latter is the method of tragedy (and comedy): without use of any narrator.
Having examined briefly the field of "poetry" in general, Aristotle proceeds to his definition of tragedy:
Tragedy is a representation of a serious, complete action which has magnitude, in embellished speech, with each of its elements [used] separately in the [various] parts [of the play] and [represented] by people acting and not by narration, accomplishing by means of pity and terror the catharsis of such emotions.
By "embellished speech", I mean that which has rhythm and melody, i.e. song. By "with its elements separately", I mean that some [parts of it] are accomplished only by means of spoken verses, and others again by means of song (1449b25-30).
He then identifies the "parts" of tragedy:
- plot (mythos)
- Refers to the "organization of incidents". It should imitate an action evoking pity and fear. The plot involves a change from bad towards good, or good towards bad. Complex plots have reversals and recognitions. These and suffering (or violence) are used to evoke the tragic emotions. The most tragic plot pushes a good character towards undeserved misfortune because of a mistake (hamartia). Plots revolving around such a mistake are more tragic than plots with two sides and an opposite outcome for the good and the bad. Violent situations are most tragic if they are between friends and family. Threats can be resolved (best last) by being done in knowledge, done in ignorance and then discovered, almost be done in ignorance but be discovered in the last moment.
- Actions should be follow logically from the situation created by what has happened before, and from the character of the agent. This goes for recognitions and reversals as well, as even surprises are more satisfying to the audience if they afterwards are seen as a plausible or necessary consequence.
- character (ethos)
- Character is the moral or ethical character of the agents. It is revealed when the agent makes moral choices. In a perfect tragedy, the character will support the plot, which means personal motivations and traits will somehow connect parts of the cause-and-effect chain of actions producing pity and fear.
- Main character should be
- good—Aristotle explains that audiences do not like, for example, villains "making fortune from misery" in the end. It might happen though, and might make the play interesting. Nevertheless, the moral is at stake here and morals are important to make people happy (people can, for example, see tragedy because they want to release their anger)
- appropriate—if a character is supposed to be wise, it is unlikely he is young (supposing wisdom is gained with age)
- consistent—if a person is a soldier, he is unlikely to be scared of blood (if this soldier is scared of blood it must be explained and play some role in the story to avoid confusing the audience); it is also "good" if a character doesn't change opinion "that much" if the play is not "driven" by who characters are, but by what they do (audience is confused in case of unexpected shifts in behaviour [and its reasons and morals] of characters)
- "consistently inconsistent"—if a character always behaves foolishly it is strange if he suddenly becomes smart. In this case it would be good to explain such change, otherwise the audience may be confused. If character changes opinion a lot it should be clear he is a character who has this trait, not a real life person - this is also to avoid confusion
- thought (dianoia)—spoken (usually) reasoning of human characters can explain the characters or story background
- diction (lexis) Lexis is better translated according to some as "speech" or "language." Otherwise, the relevant necessary condition stemming from logos in the definition (language) has no followup: mythos (plot) could be done by dancers or pantomime artists, given Chs 1, 2 and 4, if the actions are structured (on stage, as drama was usually done), just like plot for us can be given in film or in a story-ballet with no words.
- Refers to the quality of speech in tragedy. Speeches should reflect character, the moral qualities of those on the stage. The expression of the meaning of the words.
- melody (melos) "Melos" can also mean "music-dance" as some musicologists recognize, especially given that its primary meaning in ancient Greek is "limb" (an arm or a leg). This is arguably more sensible because then Aristotle is conveying what the chorus actually did.
- The Chorus too should be regarded as one of the actors. It should be an integral part of the whole, and share in the action. Should be contributed to the unity of the plot. It is a very real factor in the pleasure of the drama.
- spectacle (opsis)
- Refers to the visual apparatus of the play, including set, costumes and props (anything you can see). Aristotle calls spectacle the "least artistic" element of tragedy, and the "least connected with the work of the poet (playwright). For example: if the play has "beautiful" costumes and "bad" acting and "bad" story, there is "something wrong" with it. Even though that "beauty" may save the play it is "not a nice thing".
He offers the earliest-surviving explanation for the origins of tragedy and comedy:
Anyway, arising from an improvisatory beginning (both tragedy and comedy—tragedy from the leaders of the dithyramb, and comedy from the leaders of the phallic processions which even now continue as a custom in many of our cities) [...] (1449a10-13)
