Key components of argumentation[2]
1. Understanding and identifying arguments, either explicit or implied, and the goals of the participants in the different types of dialogue.
2. Identifying the premises from which conclusions are derived.
3. Establishing the "burden of proof" — determining who made the initial claim and is thus responsible for providing evidence why his/her position merits acceptance.
4. For the one carrying the "burden of proof", the advocate, to marshal evidence for his/her position in order to convince or force the opponent's acceptance. The method by which this is accomplished is producing valid, sound, and cogent arguments, devoid of weaknesses, and not easily attacked.
5. In a debate, fulfillment of the burden of proof creates a burden of rejoinder. One must try to identify faulty reasoning in the opponent’s argument, to attack the reasons/premises of the argument, to provide counterexamples if possible, to identify any logical fallacies, and to show why a valid conclusion cannot be derived from the reasons provided for his/her argument.
Components of Argument[3]
In The Uses of Argument (1958), Stephen Toulmin proposed a layout containing six interrelated components for analyzing arguments:
1. Claim - Conclusions whose merit must be established. 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)
2. Data - The facts we appeal 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)
3. Warrant - The statement authorizing our movement from the data to the claim. In order to move from the data 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 & 2 with the statement “A man born in Bermuda will legally be a British Citizen.” (3)
4. 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.”
5. Rebuttal - Statements recognizing the restrictions to which the claim may legitimately be applied. 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.”
6. Qualifier - Words or phrases expressing the speaker’s degree of force or certainty concerning the claim. Such words or phrases include “possible,” “probably,” “impossible,” “certainly,” “presumably,” “as far as the evidence goes,” or “necessarily.” The claim “I am definitely a British citizen” has a greater degree of force than the claim “I am a British citizen, presumably.”
The first three elements “claim,” “data,” and “warrant” are considered as the essential components of practical arguments, while the second triad “qualifier,” “backing,” and “rebuttal” may not be needed in some arguments.
