Aristotle defines rhetoric as the power of observing, in any given case, the available means of persuasion (Rhetoric I.2, 1355b25-26). It trains you to say a true thing so that a particular audience can follow it, and to meet the strongest objection instead of avoiding it. Every proposal, report and advertisement you meet is also an attempt to persuade you, so the art is as useful for hearing as for speaking.
The guiding questionHow can I persuade honestly, and how can I tell when I am being persuaded?
Round 1 opens soon
The spiral
Three strands, three rounds
Each strand comes back in every round, a level deeper. Finish Round 1 across the arts before Round 2: breadth first, then depth.
Round I Foundations
- Ethos, pathos and logosMark the three appeals in a short speechI can mark ethos, pathos and logos in a short persuasive text and say which does most of the work.
- Plain styleSay one idea plainly to one readerI can explain one idea in about 150 words to a stated kind of reader, using concrete words, and get them to restate my main point.
- Objection and stasisState the strongest objection to your own claimI can state a claim, and then the strongest objection to it in words its holder would accept.
Round II Practice
- Ethos, pathos and logosMake a case that uses all three appeals honestlyI can write a 300-word case for a position that uses character, feeling and reasoning, and check that each claim in it is true and sourced.
- Plain styleExplain the same idea to two audiencesI can explain one idea to an expert and to a non-specialist, keeping the claims the same and changing only what each reader needs.
- Objection and stasisFind the point at issueI can classify the point at issue in a dispute as a question of fact, definition, quality or procedure, and write a reply aimed at that point.
Round III Mastery
- Ethos, pathos and logosTell persuasion from manipulationI can tell honest persuasion from manipulation in a real text, using the test of whether it works by giving the hearer reasons they can check.
- Plain styleKeep the uncertainty when you cutI can shorten a hedged technical statement without turning uncertainty into false certainty, and defend each cut.
- Objection and stasisDefend a thesis against its best objection in an essayI can write an essay of 600 to 1,000 words that states the strongest objection fairly, answers it, and says what would change my mind.

Rhetoric · Round 1
- Gorgias, Encomium of Helen, sections 6 to 10, with the summary at section 15 (Diels-Kranz 82 B11)LaRue Van Hook's 1913 translation (Classical Weekly 6, no. 16), public domain in the United States, but partial: it gives sections 1 to 10, 15 and 19 to 21, so sections 11 to 14 are not on the page. Section 6 lists the four possible causes of Helen's flight; section 8 begins the account of the power of speech.
- Plato, Gorgias, 447a-466aW. R. M. Lamb's Loeb translation with the Greek, on Perseus. Socrates asks Gorgias what rhetoric is from 447c; belief and knowledge are separated at 454c-455a; rhetoric is called a knack and a part of flattery at 462b-466a.
Gorgias says that speech is a powerful lord that can end fear and stir pity, and he uses that power to excuse Helen. Plato's Socrates says the same craft is a knack for flattering people who do not know. Is the power of speech a reason to trust the speaker or to distrust him?
- Socrates separates persuasion that produces belief from persuasion that produces knowledge (454c-455a). Which kind does the Helen produce in its hearer?
- Gorgias sums up that if Helen was won over by persuasion she deserves pity, not blame (section 15). Is a listener ever responsible for being persuaded?
- At 462b-466a Socrates compares rhetoric with cookery. What would rhetoric need to have in order to count as a craft in his sense, and does the Helen have it?
Rhetoric · Round 2
- Aristotle, Rhetoric, I.1-2 (Bekker 1354a1 to 1358a35)J. H. Freese's Loeb translation (1926) on Perseus; the Greek text on the same site can be browsed by Bekker page. Chapter 1 argues that rhetoric is the counterpart of dialectic and defends its use; chapter 2 defines it at 1355b25-26 and gives the three kinds of proof at 1356a1-20.
Aristotle calls rhetoric the counterpart of dialectic, and says it is useful because the true and the just are by nature stronger than their opposites (1355a21). If that is so, why are true and just causes ever lost, and what does skill in speaking add that the truth does not already supply?
- He names three kinds of proof: the character of the speaker, the state of mind of the hearer, and the argument itself (1356a1-20). Which of these can be separated from the other two, and which cannot?
- He answers the charge that rhetoric can do harm by saying that the same objection applies to every good thing except virtue (1355b2-7). Is that a good defence?
- Aristotle says rhetoric has no subject of its own but observes the means of persuasion in any given case (1355b25-34). How does this differ from a craft such as medicine, and is it a strength or a weakness?
Rhetoric · Round 3
- Plato, Phaedrus, 257b-279cH. N. Fowler's Loeb translation with the Greek, on Perseus. Key places: the speaker must know the truth (259e-262c); rhetoric as leading the soul by words (261a, 270b-272b); Theuth and Thamus on writing (274c-275b); writing cannot defend itself (275d-e); the farmer and the seeds (276b-277a); the speaker is better called a lover of wisdom (278d).
Socrates says that no one can be a true rhetorician without knowing the truth about his subject and the kinds of soul he addresses (259e-262c, 270b-272b), and that writing, which cannot answer questions or defend itself, is only a reminder (275d-278a). What should we make of a written argument meant to persuade, including a book?
- Theuth offers writing as a cure for forgetting and Thamus replies that it will produce forgetfulness (274e-275b). Name a technology that has its own Theuth and Thamus, and say what each would claim.
- Socrates says the art of speaking must resemble medicine and know the nature of the whole it treats (270b-d). Is such a rhetoric possible for a speaker addressing a crowd he cannot know one by one?
- At the end Socrates says 'lover of wisdom' suits such a speaker better than 'wise' (278d). What does that change about the demand at 259e that the speaker must know the truth?
