  1. The Toulmin Model, developed by British philospher Stephen Toulmin, identified a 6-step process of logical argumentation which employs both inductive (general/specific) and deductive logic (specific/general) . • The method describes a powerful way to shape and understand argument in a convincing and reasonable arguments. Toulmin Argument

  2. Claim • Grounds • Warrant • Backing • Reservation/Rebuttal • Qualifier 6 Steps to Analyzing Argument

  3. A claim is a debatable and controversial statement or assertion you hope to prove. This includes information you are asking them to accept as true or actions you want them to accept and enact. Sometimes, the claim involves a question of definition (It’s raining. No, it’s not; that’s sleet) • A claim is just a lonely statement, waiting the company of evidence and good reasons. • For example, Claim

  4. Scenario: Lately you keep having to repeat everything to your grandfather. What is an example of a claim you might make to him? • CLAIM: Grandfather needs a hearing aid Why isn’t a claim enough? Family members will not simply agree. Family will ask why, and you will need to prove your claim. This is where …. You need reasons (grounds) to support your claim Evidence & Reasons So CLAIM You need Grounds

  5. Claim: Grandfather needs a hearing aid • Grounds: Over 70% of all people over 65 years have a hearing difficulty Toulmin Argument

  6. Grounds are the evidence that proves the claim. • The grounds are the evidence, data and reasoning behind the claim. It is the “truth” on which the claim is based, may include proof of expertise, and the basic premises on which the rest of the argument is built. Grounds

  7. It is critical to the argument that the grounds are not challenged because if they are, they may become a claim, which you will need to prove with even deeper information and further argument. • What addition grounds can we add to the claim? • Claim: Grandfather needs a hearing aid • Grounds: • Over 70% of all people over 65 years have a hearing difficulty • He constantly replies, “What I can’t hear you.” • We constantly repeat ourselves to him Grounds (contd.)

  8. Your audience will begin to question your statement. • Anticipate the challenges to your claims. • Anticipate the assumptions your audience will make. • Know core values of audience and or common assumptions you share. Anticipate Counterclaim

  9. This is the inference or assumption that makes the connection between the claim and the grounds. It legitimizes the claim by showing the grounds to be relevant. • It is often unstated and is based on assumptions that make the claim seem plausible. It’s often a value or principle you share with audience. Therefore, “knowing” your audience is important. Warrant

  10. Warrants answers the unspoken audience questions: • “Why does that data mean your claim is true?” Or, • “How did you arrive at that claim based upon the grounds?” • What might be a warrant you could offer in the claim with grandfather? Warrant (contd.)

  11. Claim: Grandfather needs a hearing aid • Grounds: • Over 70% of all people over 65 years have a hearing difficulty • He constantly replies, “What? I can’t hear you.” • We constantly repeat ourselves to him • Warrant: A hearing aid helps most people to hear better. What other warrants can we add? Toulmin Argument

  12. Warrants may be based on logos, ethos, or pathos, or values that are assumed to be shared with the listener. • You try it! Complete the statement. Since most people believe _warrant___ and _evidence___ is a fact, _claim. . Reason(s) So Claim Since Warrant

  13. Now, let’s try analyze “The Declaration of Independence.” Identify the following the: • Audience • Claim • Grounds • Warrants The Declaration of Independence

  14. A warrant can be classified according to purpose and type: • Authoritative warrants – rely on expert testimony to verify a claim; generically state that “qualified sources conclude that based on this data the following conclusion is justified;” dependent on backing offered in terms of expert testimony. What is an example of an authoritative warrant does Jefferson use? • Motivational warrants – rely on appeals to the audience’s convictions, virtues, and values to support the claim. Speakers must rely on precise audience analysis in order to understand what motivational appeals would be effective. Identify an example of a motivational warrant? Warrant (contd.)

  15. Claim • Grounds • Warrant • Backing • Reservation/Rebuttal • Qualifier Backing

  16. Backing is the supportfor an argument and gives additional support to the warrant byanswering different questions. • helpsaudience understand the reasoning used in the warrant. • justifies the warrant. • helpsaudience understand the reasoning used in the warrant. • With backing, the argument (and the speaker) seems more credible. • Without backing, audience only has a skeleton of the argument (claims and warrants). Therefore the audience may question the reasoning in the argument. Backing

  17. Have you ever listened to a debate or talk radio? • Have you ever noticed the people - who hold a conversation with the host, flesh out the basic claims with facts, personal experience, and evidence – present a convincing argument? • Have you noticed weaker callers who offer a claim, then repeat themselves as if saying the claim repeatedly proves the point? • There’s no point defending a claim until you’ve satisfied the audience that any questionable warrants the claim is based on are, in fact, defensible.

  18. The evidence you offer to support a warrant (core value or assumption) is called backing. • It can include any type of support material: statistics, examples, testimony. Backing and Statistics

  19. Statistics use numbers to quantify things, but they can create an illusion of “truth” (“There are lies, damn lies, and statistics.”).

  20. Examples are concrete instances or situations that illustrate the warrant. • Clearer because they provide a “real world” illustration of what is being said. • There is a danger in generalizing an example to be true in all situations. Backing and Examples

  21. Testimony involves use of expert opinion or personal experience, both of which can add credibility. • Example of Backing: Claim – The government should tax companies for the pollution they produce. Warrant – Pollution harms the health of citizens. Possible Backing – statistics from scientific studies on effects of air pollution. Backing and Testimony

  22. Another example: • Claim – Handguns should be banned. • Grounds – Handguns were involved in 20,000 deaths last year. • Warrant – Handguns cause needless deaths. • Backing – a quote from James Brady, former Reagan press secretary, who was shot and permanently injured by John Hinckley. • What might be a backing you could offer in the argument with your grandfather? Example o f Backing

  23. Claim: Grandfather needs a hearing aid • Grounds: Over 70% of all people over 65 years have a hearing difficulty • Warrant: • A hearing aid helps most people to hear better. • Hearing aids are expensive • Backing: Hearing aids are available locally. What other backing can you offer? How does backing justify or strengthen the warrant? Toulmin Argument

  24. In Toulmin’s model, arguments are not universally true. • Despite the careful construction of the argument, there may still be counter-arguments or exceptionsto the claim. • The rebuttal refutes the opposing view or counterargument. • Or it anticipates the counter-argument by giving the rebuttal during the initial presentation of the argument. Reservation/Rebuttal

  25. Imagine a crowd of “prospective audience members” hovering over your shoulder asking hard questions. • Imagine the skeptic, demanding, testy member who will question EVERYTHING! • Imagining these audience members, can help you foresee the objections and reservations. Potential objections are counterclaims (aka. conditions of rebuttal, opposing views, counterpoints, reservations, etc.). • Counterclaims are a natural part of argument. • But how do you defuse counterclaims? • How do you point out strengths and limitations of counterclaims in a manner that neutralizes concerns and possible biases? Rebuttal

  26. Predict the counterargument this statement rebuts: • Claim: Grandfather needs a hearing aid • Grounds: Over 70% of all people over 65 years have a hearing difficulty • Warrant: A hearing aid helps most people to hear better. • Backing: Hearing aids are available locally. • Rebuttal: There is a support desk that deals with technical problems if your hearing aid does not work properly. Rebuttal

  27. Claim • Grounds • Warrant • Backing • Reservation/Rebuttal • Qualifier Qualifiers

  28. Qualifiers verbalize the relative strength of an argument. • Toulmin’s system works so well because it does acknowledge the limits of a claim with words such as most, usually, presumably, almost, in some cases, possibly, for the most part, few, routinely, always or sometimes. • Qualifiers and reservations are often used by advertisers who are constrained not to lie. Thus they slip 'usually', 'virtually', 'unless' and so on into their claims. Just listen the little voice at the end of a commercial that rapidly covers the conditions and side effects of a new drug. Qualifier

  29. Example: If you were arguing that a certain film is one people would enjoy, you might say people “will probably” enjoy it since you cannot predict with certainty the subjective experience of others. • Another example: Claim – Handguns are leading to the destruction of the school system. Qualifier – Handguns are “likely” one of the key factors leading to the erosion of American schools. • What is an example of a qualifier for the claim about your grandfather’s hearing? Qualifier (contd.)

  30. Claim: Grandfather needs a hearing aid • Grounds: Over 70% of all people over 65 years have a hearing difficulty • Warrant: A hearing aid helps most people to hear better. • Backing: Hearing aids are available locally. • Reservations: Grandfather won’t know how to use it properly. • Rebuttal: There is a support desk that deals with technical problems • Qualifiers: Hearing aids help most people. Or, unless there is evidence to the contrary, hearing aids do no harm to ears. Toulmin Argument

  31. Now, let’s finish analyzing “The Declaration of Independence.” Identify the following the: • Audience • Claim • Grounds • Warrants • Counterclaim/Reservations • Rebuttal • Qualifiers The Declaration of Independence

  32. Toulmin Model

  33. Create a visual representation of Toulmin’s argument for: 1.

  34. Toulmin

  35. Now that you are ‘familiar’ with the Toulmin model, this sentence should be easy to complete: Because _______, therefore _______ since _________. In analyzing an argument, fill in the • first blank with the data or support (grounds) • second with the assertion, or claim, • and, third with the unstated assumptions warrant. A warrant — usually tacit or unspoken — is the assumption necessarily shared by the speaker, or writer, and the audience; it establishes the logical connection between the data and the claim. With this formula, a claim seems not merely an assertion but rather the logical conclusion that must be reached after testing evidence that supports a belief. Becausesuch an approach helps students understand the elements of an argument, it is thereforea valuable pedagogical technique, since greater understanding among our students is a desirable quality. Did you will notice the Toulmin model at work in that last sentence?
