Lesson 5, “Arrangement: The Second of the Five Canons.” pp. 33-35
Arrangement of arguments is based on the weight, or relative importance, of arguments. The overall arrangement of arguments is very important in accomplishing goals.
Wilson also looks at overall plans. “The basic arrangement of the entire talk looks like this: you have an exordium, a narratio, proofs, and peroration” (Wilson 2011, p. 33). In the exordium the topic is introduced. The narratio lays out facts, while the proofs make the actual arguments. The peroration is a conclusion.
On p. 34 Wilson lays out a speech in more detail, using all the Latin terms: exordium, narratio, partitio, confirmatio, refutatio, peroratio. He will discuss all the portions in greater detail later in his book. Of note for now is that the confirmatio makes arguments for the thesis while in the refutatio the arguments against the thesis are brought up and rejected.
