Warrants in an Argument

Introduction to Warrants in Argumentation

Understanding the Concept of Warrants

• Mark Sutton introduces the concept of warrants, which are integral to argumentation as developed by Stephen Toulmin.

• A claim is defined as the main point an argument seeks to prove, while reasons provide support for that claim and must be backed by evidence.

• The connection between claims and reasons is established through warrants, which serve as a bridge illustrating the validity of the argument.

Types of Warrants

Warrant by Sign

• An example illustrates a warrant by sign: "The building is on fire because I see smoke," where smoke indicates fire.

• Another example shows that having a fever implies sickness, linking high temperature with health assumptions.

Warrant by Generalization

• This type draws from general truths about groups; for instance, being over 18 suggests Joe may be a college student due to common age norms.

• Another example states "I am a good writer because I'm an English major," relying on generalizations about English majors' writing skills.

Warrant by Analogy

• Analogies emphasize similarities; for instance, wearing a lucky shirt at games connects past success with future expectations.

• A second analogy example links today's expected coolness to yesterday's weather patterns.

Causal Relationships and Authority in Warrants

Causal Warrant

• Causal warrants assume one part causes another; e.g., "I studied hard, therefore I will pass the test," where studying leads to passing.

Authority-Based Warrant

• This warrant relies on authority figures; for instance, claiming something is bad based on parental advice assumes their expertise in behavior.

Principle-Based Warrants and Conclusion

Principle-Based Warrant

• These draw upon shared beliefs or values; arguing against harmful traps uses ethical principles regarding animal treatment.

Summary of Key Concepts

• A warrant connects reasons to claims and can be stated or implied. Six types were discussed: sign, generalization, analogy, causal relationships, authority, and principle-based warrants.
