Classical rhetoric in the context of "Art (skill)"

Inventio, one of the five canons of rhetoric, is the method used for the discovery of arguments in Western rhetoric and comes from the Latin word, meaning "invention" or "discovery". Inventio is the central, indispensable canon of rhetoric, and traditionally means a systematic search for arguments.

Speakers use inventio when they begin the thought process of forming and developing an effective argument. Often, the invention phase can be seen as the first step in an attempt to generate ideas or create an argument that is convincing and compelling. The other four canons of classical rhetoric (namely dispositio, elocutio, memoria, and pronuntiatio) rely on their interrelationship with invention.

Doxa (Ancient Greek: δόξα; from verb δοκεῖν, dokein, 'to appear, to seem, to think, to accept') is a common belief or popular opinion. In classical rhetoric, doxa is contrasted with episteme ('knowledge').

In classical rhetoric, figures of speech are classified as one of the four fundamental rhetorical operations or quadripartita ratio: addition (adiectio), omission (detractio), substitution (substitutio) and transposition (transmutatio).

The consolatio or consolatory oration is a type of ceremonial oratory, typically used rhetorically to comfort mourners at funerals. It was one of the most popular classical rhetoric topics, and received new impetus under Renaissance humanism.
