Aristotle's work on aesthetics consists of the Poetics 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–survives. The lost second part addressed comedy. Scholars speculate that the Tractatus coislinianus summarises the contents of the lost second book.
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 an epic: 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. 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.
- 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 any work of their supplies matter for several tragedies. Considers tragedy a higher form of art.
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.
- 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).
Tragedy consists of six parts, which Aristotle enumerates in order of importance, beginning with the most essential and ending with the least: Aristotle considers Tragedy superior to Epics and considers them higher forms of art. Tragedies are said to be an "imitation of an action that is serious." Tragedies are written in a dramatic form with dialogue between multiple character, and not in traditional narrative form. Tragedy should make the viewer feel fear and pity. Tragedy arouses the emotions of pity and fear in order to purge away their excess, to reduce these passions to a healthy level. Aristotle also talks about “pleasure” that is proper to tragedy, apparently meaning the aesthetic pleasure one gets from contemplating the pity and fear that are aroused through the play. Tragedy is rooted in the fundamental order of the universe; it creates a cause-and-effect chain that clearly reveals what may happen at any time or place because that is the way the world operates.
- plot (mythos)
- Refers to the "structure of incidents" (actions). Key elements of the plot are reversals, recognition, and suffering. The best plot should be "complex" (i.e. involve a change of fortune). It should imitate actions arousing fear and pity. Thus it should proceed from good fortune to bad and involve a high degree of suffering for the protagonist, usually involving physical harm or death.
- Actions should be logical and follow naturally from actions that precede them. They will be more satisfying to the audience if they come about by surprise or seeming coincidence and are only afterward seen as plausible, even necessary.
- When a character is unfortunate by reversal(s) of fortune (peripeteia known today in pop culture as a plot twist), at first he suffers (pathos) and then he can realize (anagnorisis) the cause of his misery or a way to be released from the misery.
- character (ethos)
- It is much better if a tragical accident happens to a hero because of a mistake he makes (hamartia) instead of things that might happen anyway. That is because the audience is more likely to be "moved" by it. A hero may have made it knowingly (in Medea) or unknowingly (Oedipus). A hero may leave a deed undone (due to timely discovery, knowledge present at the point of doing deed). Character is the moral or ethical character in tragic play. In a perfect tragedy, the character will support the plot, which means personal motivations 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)
- 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)
- 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". Spectacle is like a suspenseful horror film.
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)
