What Is Rhetoric? The Craft of Making an Argument Land
By the BrainSnail editorial team. How these articles are written and checked, and how to tell us when one is wrong.
Rhetoric is now mostly used as an accusation, meaning empty words as opposed to substance. For two thousand years it meant something else: the systematic study of how to make a case effectively to a particular audience in a particular situation, taught as a core subject because a citizen who could not argue in public could not participate in public life.
The three appeals
Aristotle's analysis, written in the fourth century BCE, identified three means of persuasion, and the framework has survived because it is genuinely exhaustive of what a speaker has to work with. Ethos is the credibility of the speaker, which comes from demonstrated competence, evident good character and visible goodwill towards the audience, and is largely established before the argument begins. Pathos is the emotional response the argument evokes, which Aristotle treated as legitimate rather than as manipulation, on the reasoning that people feel differently about things that genuinely differ and that a speaker who describes a situation accurately will produce the feeling appropriate to it. Logos is the reasoning itself, the evidence and inference offered. The important claim is that all three are always operating, so a speaker who presents impeccable reasoning with no credibility and no emotional register is not being neutral but is simply using one channel badly, which is why technically correct arguments frequently fail to persuade anyone.
The classical system
Roman teaching organised the whole discipline into five stages of producing a speech, which remain a usable structure for any piece of persuasive work:
- •Invention, finding the available arguments, which used systematic prompts called topics to generate lines of approach rather than waiting for inspiration
- •Arrangement, ordering the material, conventionally through an introduction, a statement of facts, a division of the issues, proof, refutation of opposing arguments and a conclusion
- •Style, choosing the language, including the figures of speech that carry emphasis and rhythm
- •Memory, holding the speech without notes, which produced the method of loci, the memory palace technique still taught today
- •Delivery, meaning voice, pace, pause and gesture, which Demosthenes reportedly named as the first, second and third most important parts of oratory
- •Three broad settings were distinguished: forensic speech about past events in a court, deliberative speech about future action in an assembly, and ceremonial speech praising or blaming in the present
The figures and what they do
Rhetorical figures are frequently taught as ornament and are better understood as devices that do specific work on attention and memory. Repetition at the start of successive clauses builds momentum and makes a passage quotable, which is why it appears in almost every famous speech. Tricolon, grouping in threes, feels complete in a way that pairs and fours do not, and is the reason so many slogans have three parts. Antithesis sets two ideas against each other in parallel structure, which makes a contrast feel logically inevitable. A rhetorical question recruits the listener into supplying the answer, which is more persuasive than being told it. Chiasmus reverses a structure to produce an apparent insight from a symmetry. The reason these are worth recognising is defensive as well as productive: a passage that feels compelling for reasons the listener cannot identify is frequently using a figure, and noticing the device allows the underlying claim to be assessed separately from the pleasure of the construction.
Why it became a term of abuse
The suspicion is as old as the subject. Plato attacked rhetoric in the Gorgias as a knack for flattery that produces belief without knowledge, comparable to cookery as against medicine, and the charge that it teaches people to make the weaker argument appear stronger was levelled at the sophists who taught it for pay. Aristotle's response was that rhetoric is a neutral capacity like any skill, that the truth has a natural advantage if argued competently, and that someone who refuses to learn persuasion simply loses to those who have. The modern collapse of the word into empty words tracks a broader shift, since rhetoric was removed from general education over the nineteenth and twentieth centuries, leaving the techniques in continuous use by advertisers, campaigners and politicians while the public analysis of them largely disappeared from schooling. The argument for restoring it is defensive: the techniques work whether or not an audience can name them, and naming them is the only reliable protection.
The takeaway
Rhetoric is the systematic study of persuasion, organised by Aristotle around credibility, emotion and reasoning, all three of which operate whether a speaker attends to them or not. Roman teaching divided the work into invention, arrangement, style, memory and delivery, and distinguished court, assembly and ceremonial settings. Figures such as repetition, grouping in threes and antithesis act on attention and memory rather than decorating. Plato's charge that it produces belief without knowledge is why the word became an insult.
