Logical Fallacy

No Description

PRESENTATION OUTLINE

LOGICAL FALLACY

CIRCULAR ARGUMENT

  • Begins with what you want to end up with
  • Logically valid because premise is true, so conclusion has to be true too.
  • Circular logic can't be proven
  • God says the bible is true, the bible says God is true

SLIPPERY SLOPE

  • It is showing that some event must invevitable
  • follow from another without any argument
  • for the inevitability of the event in question
  • Example:" we have to stop tuition increase! The next thing
  • you know, they'll be charging 40,000 a semester

STRAW MAN

  • Straw man fallacy happens when someone makes a suggestion
  • and another person substitutes an exaggerated and distorted version of the suggestion
  • Example: Jill: "We should clean out the closets. They are getting a bit messy."
  • Bill: "Why, we just went through those closets last year. Do we have to clean them out everyday?"
  • Jill: "I never said anything about cleaning them out every day. You just want too keep all your junk forever, which is just ridiculous."

POST HOC ERGO PROPTER HOC

  • "After this, therefore because of this"
  • Since event B happened after event A, event A has to be the cause for B
  • Comes to a conclusion based only on the order of events
  • I wore my favorite jersey for the game and we won, therefore I'm going to wear it for every game.
