Invention

Invention
One of the five canons of rhetoric, Invention is "the art of discovering all of the arguments and evidence available for a particular rhetorical situation."



Commonplace
A commonplace is any statement, idea, or piece of knowledge that is shared by an audience or a community. For example, Jesus Christ and his crucifixation is a commonplace in the Christian community, and Pastors/Priests use ths to connect with their audience.

Stasis Theory
Statis Theory is a systematic way of asking questions about rhetorical situations. It is one of the means of invention in rhetoric. Stasis Theory involves a system of questions that assist rhetoricians while they attempt to determine exactly what the disagreement is between themselves and their audience.

Kairos
A means of invention that refers to a situation or time that gives the rhetorician an advantage. "Under the doctrine of kairos, the truth depends on a careful consideration of all factors sorrounding an event, including time, opportunity, and circumstances." Learning when to use certain appeals and tropes depends on many factors. The time, place, audience, and issue at hand are all tied with kairos.
