4. The Toulmin Model
Developed by British philosopher Stephen Toulmin in the 1950’s
Emphasizes that logic often based on probability rather than certainty
Focuses on claims
Informal logic: based on probability. Gives good reasons, persuasive arguments. Does not attempt to prove….
Acknowledges reasonable arguments of both sides
Seven components

5. Toulmin Model: Three Components
Claim = statement of the main point or position Data = the evidence supporting the claim, aka the reasons Warrant = an underlying/unstated assumption or basic principle that connects data and claim; as said before, perhaps implied rather than explicit

6. Toulmin Model: Other Components
Grounds: provide actual evidence in support of the reasons.
Examples, statistics, citations, facts
Backing: supports warrant, if needed.
Conditions of Rebuttal: bring up and address counter- arguments. Attacks grounds and/or the warrant and backing.
Qualifier: limits a claim. Gets rid of absolutes. Can prove a claim is faulty if given absolutes like always, never…..can find exceptions to such broad statements.

8. Toulmin Model: An Example
Claim = My parents should allow me to go to my friend’s party on Friday night. Data = The parents of nearly all of the seniors at CHS have given their children permission to attend this party. Warrant = My parents should act in accordance with the other parents of juniors at CHS.

9. Uh-oh, a potential snag…
What if my parents don’t “buy” my warrant? What if they don’t think they should necessarily do what other parents are doing? How can I still get permission to attend the party? Or at least have a better chance of getting permission?

10. Try new data and a new warrant.
What might be more convincing data for an audience of parents? What might be a warrant that most parents will share?

11. Rogerian Model
Developed by psychologist Carl Rogers (also in the ’50s)
Emphasizes problem-solving and/or coming to consensus
Mutually acceptable solutions to problems
Allows the author to appear open-minded or even objective
Appropriate in contexts where you need to convince a resistant opponent to at least respect your views

12. Rogerian Model Seeks common ground Builds trust Reduces threat
Avoids confrontation/attack
Gives credit to counterarguments

13. Rogerian Arguments: Structure
Introduction: statement of problem to be solved or question to be answered
Summary of Opposing Views: described using a seemingly objective persona
Statement of Understanding: concedes circumstances under which opposing views might be valid
Statement of Your Position
Statement of Contexts: describes contexts in which your position applies/works well
Statement of Benefits: appeals to self-interest of readers who may not yet agree with you; demonstrates how your position benefits them
