Classical Rhetoric

The five canons

Inventio — finding material

Orators found arguments by walking a fixed list of topoi — places to look: definition, cause, comparison, circumstance. That list survives in the nine question families: origin, stakes, method, choice, influence, distinction, reversal, counterfactual, threshold. The Guest Dossier and opening forms prepare invention by finding the live edge before the table.

Half of invention, however, happens live. The listening channels work from the guest’s last sentence — a charged noun, a skipped year, a metaphor doing the thinking. The answer is the material describes real-time inventio. The stockpile does not carry over: a host who arrives with a prepared argument is no longer asking.

Dispositio — arrangement

Classical orations followed a fixed order: exordium, narratio, confirmatio, refutatio, peroratio. The Profile spine descends directly from it: Entry, Origin, Work, Tension, Close. A conversation needs several spines; debates, symposia, inquiries, testimonies, and craft sessions order the hour differently.

Fixity does not carry over. An oration is ordered before the speaker stands; a conversation reorders itself as it unfolds. The transitions, Inventory, and Returning are live dispositio, ideally unseen.

Elocutio — style

Rhetoric named four virtues of style: correctness, clarity, propriety, and ornament. The host keeps the first three and mostly rejects the fourth. The question repairs and Question Workbench enforce them by cutting permission theater and double-barreled questions. Shortest question, largest space is a creed of plain style.

Figures survive sparingly: the echo, antithesis, professed puzzlement, and their kin appear in Figures, each tied to a palette move. Eloquence that draws attention to the speaker does not carry over. The host’s best sentence is the one nobody remembers as the host’s.

Memoria — memory

The ancients memorized speeches by placing vivid images in imagined rooms. A two- or three-word cue card does the same on paper: one image stands for a territory. The Thread Ledger records promises and parked topics once carried in the head.

The host’s real memoria looks backward, not forward: it commands what has been said, not what will be. Returning, Connecting Threads, and Amplifying spend recall of an earlier sentence — “an hour ago you used the word ‘debt.’ I kept it” — while Restoring the Floor preserves someone else’s thread. The memorized script does not carry over. A host who recites fails in a way the orator never could.

Actio — delivery

For the ancients, delivery — voice, face, gesture, bearing — was often the decisive canon. The host uses a narrower range: register — the voice drops before the question does — tempo, and silence held with a still face. Hold the Silence and the Silence Meter drill what a browser can time.

Much of actio turns outward. Naming the Shift and the affect channel treat the guest’s delivery — a doubled pace, a first hesitation — as material. Rehearsed gesture does not carry over; physical practice belongs at real tables. The Prompt Creator supplies a spoken practice table when none is available.

The second-person canons

Classical rhetoric is monological: one speaker controls all five canons. Hosting distributes them. Many palette moves activate a canon in the guest: the host prompts the example, summary, or plain phrasing instead of supplying it. That transfer is this site’s main departure from tradition.

What does not carry over

• Persuasion as the aim. Rhetoric seeks assent. Hosting seeks elicitation: a conversation that would not otherwise happen. A host with a thesis is a guest in the wrong chair.
• The audience as judge. The orator seeks a verdict. At the table, the audience participates; the harvest replaces the verdict.
• Ornament for display. Figures survive only when they serve the table. Eloquence noticed as eloquence is a cost.
• The memorized speech. Preparation survives; recitation does not.
• The single voice. Every canon here works with, and often through, other people.
