Extrinsic Proofs:
Arguments in the Rhetorical Situation

2. Intrinsic Proofs Ethos Pathos Logos
All of these must be invented by the speaker or writer! You have to « discover » them.

3. Extrinsic Proofs Evidence, facts, data, testimony—
All are already in the rhetorical situation…do not have to be invented.
But, we need invention to “use” them!

4. Extrinsic Proofs We moderns place a high value on them:
Police fact gathering
Legal case—facts of the case
Scientific Method
If we see it, hear it, taste it, touch it, understand it, we believe it and trust it!
In Ancient world, they put less trust in them.
Rhetors need merely to gather data, arrange it, present it with emotion and good will.
Use example here of cross-examination debate and parliamentary debate

5. Extrinsic Proofs
Ancients thought that it took skills and training to wield and invent intrinsic proofs—the art of argument.
We understand that even the gathering and collection of data and evidence requires careful training—CSI, Corner’s office, Police and detective training, scientific training.

6. What parts of a trial are intrinsic & extrinsic?
Testimony of witnesses
Testimony of experts
Testimony of accused
Physical evidence
Facts of the law
Oaths
Maxims, beliefs, community held ideas
Documents
Intrinsic?
Opening remarks
Closing remarks
Arguments made after each bit of evidence
Argumentative sayings, “If it doesn’t fit, you must acquit.”

7. Ancients knew Documents need interpretation Facts need interpretation
Evidence needs interpretation
Extrinsic Proofs alone are not always convincing
Needs the orator’s skill!!

8. Evaluating Authority & Testimony
Community authorities
People who are trusted and whose opinions and knowledge is valued in community.
What are motives and ideologies?
Proximate Authorities
(modern authority—not wise, just there)
Eye witnesses
Could they see it really?
Where there obstructions?
Are they sane?

9. Evaluating Data Don’t accept on face value! Can be partial or twisted.
Look who put out the data—can they be trusted to be even handed and fair and accurate?
Could it be skewed?
Can you think of data skewed for various purposes?
