Study Notes

  • Irrelevant premises are fallacies where the reasons offered don't logically support the conclusion

Equivocation

  • This involves misusing a word that has multiple meanings
  • Example: God is love; love is blind; therefore, God is blind

Composition

  • This fallacy attributes a characteristic of the parts to the whole
  • Example: Standing at a concert improves individual viewing, therefore, everyone standing will see better

Division

  • This is the opposite of composition, attributing a characteristic of the whole to its parts
  • Example: A sculpture is expensive; therefore, it must be made of jewels

Genetic Fallacy

  • Judges a claim based on its source rather than its content
  • Example: Disregarding information solely because it comes from Wikipedia

Appeal to the Person (Ad Hominem)

  • Attacks the person making the argument instead of the argument itself
  • Example: Dismissing someone's argument because they spread rumors about their ex

Appeal to Emotion

  • Relies on strong, but irrelevant, emotions instead of logical reasoning
  • Example: Claiming one's wife will leave if the other person rejects them

Appeal to Popularity (Ad Populum)

  • Asserts something is true because the majority approves of it
  • Example: Suggesting an unknown film is better than a highly-ranked one

Appeal to Tradition

  • Argues something is true because it's been traditionally or culturally accepted
  • Example: Claiming eating meat is moral as humans have done it for years

Appeal to Ignorance

  • Claims something is false because it hasn't been proven true
  • Example: Assuming news is false simply because it is not rejected

Red Herring

  • Introduces a misleading claim to distract from the main argument
  • Example: Recounting good memories of military service to defend mandatory service

Straw Man

  • Distorts or weakens an opponent's position to make it easier to attack

  • Example: Presenting military service opponents as enemies of the country

  • Unacceptable Premises refer to logical fallacies where the premises themselves are flawed

Begging the Question

  • Concludes a claim by simply repeating the premise in different words
  • Example: Cheating on taxes is immoral because it violates moral principles

False Dilemma (False Dichotomy)

  • Presents only two options when more exist
  • Example: Claiming you must get a degree today or you won't find a job

Slippery Slope

  • Argues that one step will inevitably lead to undesirable consequences without sufficient evidence
  • Example: Not getting a degree leads to a bad CV, unemployment, and a dead-end job

Hasty Generalization

  • Draws a conclusion about a group based on insufficient evidence
  • Example: Claiming all male Gender Studies professors are sexist based on one instance

Faulty Analogy

  • Assumes that if two things are similar in some ways, they must be similar in others
