Study Notes
Introduction
- A fallacy is an error in reasoning.
- These are flawed statements that often sound true.
- Logical fallacies are used to strengthen arguments, but can backfire if the reader detects them.
- The word "fallacy" comes from the Latin word "fallere" meaning "to deceive, to trip, to lead into error or to trick".
- It also derives from the Greek "phelos", meaning "deceitful".
- Most fallacies have their origin in Aristotle.
Why Study Logical Fallacies?
- Develop logical fallacy detection skills in your own writing, as well as others.
- Think of it as "intellectual kung-fu: the art of intellectual self-defense."
Types of Logical Fallacies
- Linguistic Fallacies
- Accent: Shifts emphasis or punctuation in a statement, altering its meaning (e.g., "Pardon impossible to be executed").
- Amphibology (Amphiboly): A statement with multiple interpretations due to ambiguous wording (e.g., "For sale: convertible car by a teacher with a damaged top").
- Equivocation: Uses the same term with different meanings in an argument (e.g., "Feathers are light, Light comes from the sun, Therefore, feathers come from the sun").
- Emotive Language and Ambiguity: Uses ill-defined or meaningless terms to incite emotional response (e.g., "Theft was not a criminal act in Sparta; consequently they did not encourage crime").
- Fallacies of Irrelevance (Argumentum ad Rem)
- Accident (dicto simpliciter or secundum quid): Applies a general rule to a specific case where it doesn't apply (e.g., "He who kills another person is a murderer... Therefore, a surgeon is a murderer").
- Fallacy of Irrelevance (ignoration elenchi): Proves or disproves the wrong point, ultimately avoiding the main issue (e.g., Instead of proving A, B is proved).
- Non Sequitor (Does Not Follow): The conclusion does not logically follow from the premises (e.g., Roses are red. Violets are blue. I love my teacher. My father has a horse.).
- False Cause (Post Hoc ergo propter hoc): Assumes that because one event precedes another, it is the cause (e.g., "It is evident that women should be elected to political office since government is similar to national housekeeping; and in this respect it is obvious that women have much more experience than men.").
- Special Pleading (Neglected Aspect): Presents only one side of the story to neglect facts that might favor the opposition (e.g., "Organized religion should be abolished on the grounds that it has incorporated masses of fables and superstitions...").
- Genetic Error: Assumes an argument is either proved or disproved based on its source (e.g., George Fox founded a religion. He became insane. The religion he founded must be false).
- Misplaced Authority: Cites an authority figure in a field where they are not competent (e.g., An individual who argues that God exists on the premise that Albert Einstein believed in God).
- Circular Reasoning or Begging the Question (Petitio Principi): Uses the conclusion to support the premise (e.g., Doorman: 'May I see your invitation?' Smith: 'I am very sorry, I mislaid mine; but Mr.Jones, who is standing beside me will vouch for me.').
More Fallacies
- Slippery Slope: Assumes a small step will lead to a chain of negative events (e.g., "If you don’t stop smoking, then you are going to start shooting heroin").
- Begging the question: A is true because A is true (e.g., "chocolate is healthy because it is good for you")
- Straw Man: Distorts or misrepresents an opponent's argument to make it easier to attack (e.g., "How could he possibly cheat on his taxes? He’s such a great father!").
- Guilt by association: Creates a false correlation between two events (e.g., 9/11- Sandy Hook shooting).
- Faulty Cause/effect: Mistakenly assumes a causal relationship between events (e.g., "we’ve been in business 50 years – That makes us the best!).
- False needs: Creates a false sense of need to persuade (e.g., "If parents want intelligent children, they must buy Baby Mozart!").
- Either/Or fallacy – aka False Dilemma: Presents only two options when there are others (e.g., "You’re either part of the solution or part of the problem").
- Poisoning the Well: Presenting negative information about a person before they speak to discredit their argument (e.g., Do not trust him, he will just hurt you).
