Argumentation Notes

Introduction to Argumentation

• Argumentation involves presenting reasons to persuade others that an action or idea is right or wrong.

Debate Structure

• Affirmative Side: Delivers the opening statement.

• Negative Side: Follows with their opening statement.

• Rebuttals:

  • The affirmative side gives their rebuttal.

  • The negative side gives their rebuttal.

• This process continues based on time and structured arguments.

• Closing Statements:

  • Affirmative side delivers closing statement.

  • Negative side delivers closing statement.

• End of debate.

Persuasion Modes

• Ethos (Credibility): Establishing trust and authority.

• Logos (Logic): Using logical reasoning, facts, and evidence.

• Pathos (Emotion): Appeal to emotions for effective communication.

Constructing Effective Arguments

• Use good premises that are true and relevant.

• Ensure premises support conclusions effectively.

• Avoid overly sweeping claims that lack support.

Supporting Arguments

• Effective arguments defend positions with appropriate evidence, which may include:

  • Facts

  • Opinions

  • Inferences

  • Statistics

• Combine rational appeals with emotional appeals for better delivery.

Logical Fallacies

• Definition: Errors in reasoning that undermine arguments, often misleading.

List of Common Logical Fallacies:

• Hasty Generalization: Making assumptions about a whole group based on inadequate evidence.

  • Example: "All philosophy classes are hard because mine is."

• Slippery Slope: Arguing that one action will lead to extreme consequences.

  • Example: "If we unlock the door, our child will be kidnapped."

• Non-Sequitor: Conclusions that do not logically follow.

  • Example: "Because drunk driving is serious, the penalty should be death."

• Stereotyping: Assuming general beliefs are true for all instances.

  • Example: "All atheists are morally bankrupt."

• Card Stacking: Presenting only partial evidence.

  • Example: "My candidate is honest because he volunteers."

• False Dichotomy: Presenting two choices when more exist.

  • Example: "We must tear down the building or risk student safety."

• Begging the Question: Assuming the truth of an unproven statement.

  • Example: "Paranormal activity is real because I experienced it."

• Circular Argument: Restating the argument without proof.

  • Example: "Bush is a good communicator because he communicates well."

• Red Herring: Diverting attention from relevant issues.

  • Example: "The mercury levels are unsafe, but what will fishers do?"

• Ad Hominem: Attacking the person instead of the argument.

  • Example: "Green Peace's strategies are ineffective because they are lazy."

• Post Hoc Ergo Propter Hoc: Assuming causation from correlation.

  • Example: "I got sick after drinking bottled water; therefore the water made me sick."

• Bandwagon Appeal: Arguing something is true because many people believe it.

  • Example: "70% of Americans think gay marriage is immoral!"

• Strawman: Misrepresenting an argument to make it easier to attack.

  • Example: "Feminists want to ban pornography; thus they are wrong."

• Appeal to False Authority: Citing a non-expert's opinion as evidence.

  • Example: "My mom says chocolate causes acne; she’s always right."

• Proof Surrogate: Suggesting evidence exists but not providing it.

  • Example: "The death penalty is needed due to rising crime rates."

Group Activity Overview

• Class will be divided into 5 groups.

• Each group assigns 3 logical fallacies to report on.

• Tasks:

  • Prepare a PPT presentation and written report.

  • Presentations span from March 24-28.

Group Roles

• Leader: Facilitates tasks and deadlines.

• Researchers: Collect varied information.

• Writers: Structurally compile information into reports.

• Presentation Designer: Create PowerPoint slides.

• Reporters: Present group's findings in class.

Logical Fallacies Assignments

• Group 1: Hasty Generalization, Slippery Slope, Non-Sequitor

• Group 2: Stereotyping, Card Stacking, False Dichotomy

• Group 3: Begging the Question, Circular Argument, Red Herring

• Group 4: Ad Hominem, Post Hoc Ergo Propter Hoc, Bandwagon Appeal

• Group 5: Strawman, Appeal to False Authority, Proof Surrogate

Conclusion

• Understanding these elements of argumentation will enhance communication and critical thinking skills in debates and discussions.
