What is toulmin

  1. 1. What is the Toulmin method of argumentation? Claim – Data - Warrant
  2. 2. Types of arguments <ul><li>The Toulmin Model </li></ul><ul><li>Claim, Data, Because </li></ul>
  3. 3. Who is Stephen Toulmin? <ul><li>He was a British philosopher who wrote a book called The Uses of Argument (1958). Toulmin was looking for a method that accurately described the way people make convincing and reasonable argument. Because Toulmin argument takes into account the complications in life— all those situations when people have to qualify their thoughts with words such as sometimes , often , presumably , unless , and almost — his method isn’t as airtight as formal logic. But for exactly that reason, Toulmin logic has become a powerful and, for the most part, practical tool for understanding and shaping argument. </li></ul>
  4. 4. Making Claims <ul><li>In the Toulmin model, arguments begin with claims, which are debatable and controversial statements or assertions you hope to prove. </li></ul><ul><li>Notice in this model the arguments depend on conditions set by others— your audience or readers. </li></ul><ul><li>It’s raining might be an innocent statement of fact in one situation; in another, it might provoke a debate: No, it’s not. That’s sleet. </li></ul><ul><li>And so argument begins, involving a question of definition. </li></ul>
  5. 5. The Toulmin Model <ul><li>Claim : the proposition that the arguer is supporting. It must be an opinion and cannot be a fact. </li></ul><ul><li>Data : the specific evidence or reason used to support the claim (often introduced with the word “because” or “since”; sometimes this is the claim of another argument) </li></ul><ul><li>Warrant : the inference that allows you to move from the grounds to the claim (often only implied in the argument) </li></ul>
  6. 6. Other Elements <ul><li>Backing – Support for the warrant, backing the reason given </li></ul><ul><li>Grounds – Facts, statistics, expert testimony, observations </li></ul><ul><li>Qualifier – Degree of certainty </li></ul>
  7. 7. Syllogism and Toulmin model compared <ul><li>Claims  Conclusion </li></ul><ul><li>Data  Minor premise </li></ul><ul><li>Warrant  Major premise </li></ul>
  8. 8. Toulmin Model Diagram <ul><li>Data  ---------------  Claim </li></ul><ul><li>Warrant </li></ul>
  9. 9. A sentence symbolizing the Toulmin model <ul><li>Because ______________________, therefore__________________, since__________________________. </li></ul><ul><li>In analyzing an argument, you would fill in the first blank with the data or support. The second with the assertion or claim, and the third with the warrant, the unspoken assumption. </li></ul>
  10. 10. Imagine someone looking over your shoulder <ul><li>As you use Toulmin, image a crowd of “prospective readers” hovering over your shoulder, asking questions. </li></ul><ul><li>At every stage in Toulmin argument— making a claim, offering a reason, or studying a warrant— you might converse with those nosy readers, imagining them as skeptical , demanding, even a bit testy. </li></ul>
  11. 11. Rebuttal <ul><li>They may get on your nerves, but they’ll likely help you foresee the objections and reservations real readers will have regarding your arguments. </li></ul><ul><li>In the Toulmin system, potential objections to a claim are called conditions of rebuttal . </li></ul><ul><li>Understanding and reacting to these conditions are essential to back up your claim where it is weak, but also to understand the reasonable objections of people who see the world differently. </li></ul>
  12. 12. Example <ul><li>Data: Because independent research has shown that 70% of students who take one A.P. class are more likely to graduate college than students who take no A.P. class. </li></ul><ul><li>Claim – Therefore all students who are academically prepared should have access to A.P. classes in high school. </li></ul><ul><li>Warrant- Since high school should prepare students for college success, students should have access to A.P. classes. </li></ul>
  13. 13. The Data-Claim-Because Model <ul><li>Data : the specific evidence or reason used to support the claim </li></ul><ul><li>Claim : The argument, contention, premise, central idea, proposition. </li></ul><ul><li>Because : the inference that the author assumes his audience thinks and believes about the claim. How do these assumptions play in the construction of his argument? </li></ul>
