Rhetorical Invention & Persuasive Memory

← Back to Domain-Specific Families

Abstractions about forensic rhetoric, invention, memory, topical resources, and moral or psychological effects that shape persuasive argument.

5 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Forensic Rhetoric — The Aristotelian speech genre whose subject is past action under judgment — what happened, who is responsible, what remedy follows — fixed by a five-element apparatus (backward time orientation, judging audience, rules of evidence, explanation and exculpation topoi, verdict-form output) that recurs across every institutionalized judgment forum.
• Invention (Rhetorical Canon) — Systematically canvass the arguments available in a case by visiting a fixed catalogue of topoi in turn, treating coverage of that space — not the quality of any one argument — as the standard of adequacy, before any choice of what to advance begins.
• Lady Macbeth effect — A proposed and replication-contested pattern in which contemplating one's own wrongdoing increases the desire for physical cleansing, and cleansing after a transgression reduces the felt need for moral repair — as if the brain conflates moral and physical purity through a shared schema.
• Memory (Rhetorical Canon) — The fourth classical rhetorical canon: the orator's living, indexed archive of arguments, examples, and passages — acquired before performance, organized for retrieval, and reachable under the pressure of a live occasion, not rote recall of a fixed script.
• Topoi — The pre-formed argument templates of rhetorical invention — a finite catalogue of move-forms (definition, a fortiori, cause-and-effect, sign, precedent) whose form is fixed and content variable — so finding arguments becomes an auditable search through a known library rather than creation ex nihilo.
