Works are also useful in analyzing rhetorical arguments
Pursued practical argumentation

3. Toulmin believed that…
Practical arguments should focus on the justificatory function as opposed to the inferential function of theoretical arguments
Theoretical arguments= make inferences on principles to arrive at claim (NOT his belief…)
Practical arguments= first find a claim of interest and then provide justification
Reasoning should not be an activity of inference but more a process of testing and sifting through already existing ideas

4. Toulmin’s structure Claim: the arguments you wish to prove
Qualifiers: any limits you place on your claim
Fact/ evidence: support for your claim
Warrants: underlying assumptions that support your claim
Backing: evidence for warrant
Rebuttal: “nodding your head” to the opposition

5. So Claim Reasons/Evidence “The mushroom is poisonous.”
“So don’t eat it!”
Since
Warrant
“Since eating poisonous things is dangerous.”

6. The optional pieces…
Backing: Support for claim, done after argument is outlined
Qualifier: acknowledges limitations
Few, it is possible, more or less, in some cases, many, typically, some, rarely, routinely, often
Rebuttal: potential objections
“unless”

7. So Claim Reasons/Evidence “Your LSAT scores are 98th percentile”
“So it is likely that you will get into
Law school.”
Since
Warrant
(qualifier)
“Since high LSAT scores are an important
factor in law school admissions.”

15. Toulmin Model of Argumentation: Required Elements
Claim (Conclusion)
A conclusion whose merit must be established. In argumentative essays, it may be called the thesis.
For example, if a person tries to convince a listener that he is a British citizen, the claim would be "I am a British citizen." (1)
Ground (Fact, Evidence, Data)
A fact one appeals to as a foundation for the claim.
For example, the person introduced in 1 can support his claim with the supporting data "I was born in Bermuda." (2)
Warrant
A statement authorizing movement from the ground to the claim.
In order to move from the ground established in 2, "I was born in Bermuda," to the claim in 1, "I am a British citizen," the person must supply a warrant to bridge the gap between 1 and 2 with the statement "A man born in Bermuda will legally be a British citizen." (3)
Toulmin believed that for a good argument to succeed, it needs to provide good justification for a claim. This, he believed, will ensure it stands up to criticism and earns a favourable verdict. In The Uses of Argument (1958), Toulmin proposed a layout containing six interrelated components for analyzing arguments:

16. Toulmin Model of Argumentation: “optional elements”
Backing
Credentials designed to certify the statement expressed in the warrant; backing must be introduced when the warrant itself is not convincing enough to the readers or the listeners.
For example, if the listener does not deem the warrant in 3 as credible, the speaker will supply the legal provisions as backing statement to show that it is true that "A man born in Bermuda will legally be a British citizen."
Rebuttal
Statements recognizing the restrictions which may legitimately be applied to the claim.
The rebuttal is exemplified as follows: "A man born in Bermuda will legally be a British citizen, unless he has betrayed Britain and has become a spy of another country."
Qualifier
Words or phrases expressing the speaker's degree of force or certainty concerning the claim. Such words or phrases include "probably," "possible," "impossible," "certainly," "presumably," "as far as the evidence goes," and "necessarily."
The claim "I am definitely a British citizen" has a greater degree of force than the claim "I am a British citizen, presumably."
