What is a fallacy?
These begin with an assumption, so they fail to establish their claim.
Fallacies of Presumption
A fallacy is, basically, an error in reasoning. Some of the most common ones will be discussed today.

Fallacies are a big issue in argument because they provide distractions from the truth.
Begging the Question
- the argument assumes exactly what it attempts to prove. (The Bible is never wrong. Whatever the Bible says is true. So, the Bible is never wrong.)

(Either-or Reasoning)- Presents an issue in only two ways. For example, "Either vote for the school bond or destroy the lives of many American children."

Hasty generalization
- someone jumps to a broad conclusion based on too little evidence (like stereotyping.)

Post hoc fallacy
- incorrectly attributing a cause and effect relationship. Ex. After Brock became a vegetarian, he lost his muscle tone.

Slippery Slope
- a false appeal to fear suggesting tat a single event will lead to a series of catastrophic events
