What is a fallacy?

Attacking Fallacies in Argumentation

  1. Standard Form of Arguments: When analyzing arguments, reconstruct them in standard form to expose implicit assumptions and questionable premises. For example:

    • Premise: Teachers are not currently engaging in collective bargaining.

    • Implicit Premise: Whatever is now a practice should continue to be the practice.

    • Conclusion: Therefore, teachers should not engage in collective bargaining.

  2. Absurd Counterexample Method: This method involves creating a parallel argument with an obviously absurd conclusion to demonstrate the flaw in reasoning.

    • Example:

    • Argument: All Marxists are atheists; Dan is an atheist; therefore, Dan must be a Marxist.

    • Counterexample: All library books are made of paper; Dan's kite is made of paper; therefore, Dan's kite is a library book.

  3. Common Fallacies:

    • Undistributed Middle Term: This fallacy creates invalid conclusions based on premises that do not connect logically.

    • Fallacy of the Continuum: This fallacy assumes no clear distinctions exist between gradual differences. For instance, one might argue that since a fetus is a human at birth, it must also be considered human at conception without recognizing stages of development.

  4. Sportsmanship in Argumentation: To maintain friendly discourse, adhere to these guidelines:

    • Don’t be a fallacy monger: Avoid obsessively pointing out every logical flaw in casual conversations.

    • Confront when necessary: Engage an opponent's reasoning only after careful consideration of significant flaws.

    • Admit your own mistakes: When caught in a fallacy, acknowledge it without making excuses.

    • Avoid the term 'fallacy': Use respectful and constructive language when critiquing others' reasoning.
